[security] Adding a NO DATA negative cache entry failed to clear any matching RRSIG records. A subsequent lookup of of NO DATA cache entry could trigger a INSIST when the unexpected RRSIG was also returned with the NO DATA cache entry. CVE-2010-3613, VU#706148. [RT #22288] 2969.

[func] Check that named successfully skips NSEC3 records that fail to match the NSEC3PARAM record currently in use. [RT# 21868] 2937. [bug] Worked around an apparent race condition in over memory conditions. Without this fix a DNS cache DB or ADB could incorrectly stay in an over memory state, effectively refusing further caching, which subsequently made a BIND 9 caching server unworkable. This fix prevents this problem from happening by polling the state of the memory context, rather than making a copy of the state, which appeared to cause a race. This is a "workaround" in that it doesn't solve the possible race per se, but several experiments proved this change solves the symptom. Also, the polling overhead hasn't been reported to be an issue. This bug should only affect a caching server that specifies a finite max-cache-size. It's also quite likely that the bug happens only when enabling threads, but it's not confirmed yet. [RT #21818] 2925. [bug] Named failed to accept uncachable negative responses from insecure zones.

[func] The default locations for named.pid and lwresd.pid are now /var/run/named/named.pid and /var/run/lwresd/lwresd.pid respectively. This allows the owner of the containing directory to be set, for "named -u" support, and allows there to be a permanent symbolic link in the path, for "named -t" support. [RT #18306] 2485. [bug] Change update's the handling of obscured RRSIG records. Not all orphaned DS records were being removed. [RT #18828] 2484. [bug] It was possible to trigger a REQUIRE failure when adding NSEC3 proofs to the response in query_addwildcardproof(). [RT #18828] 2483. [port] win32: chroot() is not supported. [RT #18805] 2482. [port] libxml2: support versions 2.7.* in addition to 2.6.*. [RT #18806] --- 9.6.0b1 released --- 2481. [bug] rbtdb.c:matchparams() failed to handle NSEC3 chain collisions. [RT #18812] 2480. [bug] named could fail to emit all the required NSEC3 records. [RT #18812] 2479. [bug] xfrout:covers was not properly initialized. [RT #18801] 2478. [bug] 'addresses' could be used uninitialized in configure_forward(). [RT #18800] 2477. [bug] dig: the global option to print the command line is +cmd not print_cmd. Update the output to reflect this. [RT #17008] 2476. [doc] ARM: improve documentation for max-journal-size and ixfr-from-differences. [RT #15909] [RT #18541] 2475. [bug] LRU cache cleanup under overmem condition could purge particular entries more aggressively. [RT #17628] 2474. [bug] ACL structures could be allocated with insufficient space, causing an array overrun. [RT #18765] 2473. [port] linux: raise the limit on open files to the possible maximum value before spawning threads; 'files' specified in named.conf doesn't seem to work with threads as expected. [RT #18784] 2472. [port] linux: check the number of available cpu's before calling chroot as it depends on "/proc". [RT #16923] 2471. [bug] named-checkzone was not reporting missing mandatory glue when sibling checks were disabled. [RT #18768] 2470. [bug] Elements of the isc_radix_node_t could be incorrectly overwritten. [RT# 18719] 2469. [port] solaris: Work around Solaris's select() limitations. [RT #18769] 2468. [bug] Resolver could try unreachable servers multiple times. [RT #18739] 2467. [bug] Failure of fcntl(F_DUPFD) wasn't logged. [RT #18740] 2466. [doc] ARM: explain max-cache-ttl 0 SERVFAIL issue. [RT #18302] 2465. [bug] Adb's handling of lame addresses was different for IPv4 and IPv6. [RT #18738] 2464. [port] linux: check that a capability is present before trying to set it. [RT #18135] 2463. [port] linux: POSIX doesn't include the IPv6 Advanced Socket API and glibc hides parts of the IPv6 Advanced Socket API as a result. This is stupid as it breaks how the two halves (Basic and Advanced) of the IPv6 Socket API were designed to be used but we have to live with it. Define _GNU_SOURCE to pull in the IPv6 Advanced Socket API. [RT #18388] 2462. [doc] Document -m (enable memory usage debugging) option for dig. [RT #18757] 2461. [port] sunos: Change #2363 was not complete. [RT #17513] --- 9.6.0a1 released --- 2460. [bug] Don't call dns_db_getnsec3parameters() on the cache. [RT #18697] 2459. [contrib] Import dnssec-zkt to contrib/zkt. [RT #18448] 2458. [doc] ARM: update and correction for max-cache-size. [RT #18294] 2457. [tuning] max-cache-size is reverted to 0, the previous default. It should be safe because expired cache entries are also purged. [RT #18684] 2456. [bug] In ACLs, ::/0 and 0.0.0.0/0 would both match any address, regardless of family. They now correctly distinguish IPv4 from IPv6. [RT #18559] 2455. [bug] Stop metadata being transferred via axfr/ixfr. [RT #18639] 2454. [func] nsupdate: you can now set a default ttl. [RT #18317] 2453. [bug] Remove NULL pointer dereference in dns_journal_print(). [RT #18316] 2452. [func] Improve bin/test/journalprint. [RT #18316] 2451.

[cleanup] libbind has been split out as a separate product. 2446. [func] Add a new log message about build options on startup. A new command-line option '-V' for named is also provided to show this information. [RT# 18645] 2445. [doc] ARM out-of-date on empty reverse zones (list includes RFC1918 address, but these are not yet compiled in). [RT #18578] 2444. [port] Linux, FreeBSD, AIX: Turn off path mtu discovery (clear DF) for UDP responses and requests. 2443. [bug] win32: UDP connect() would not generate an event, and so connected UDP sockets would never clean up. Fix this by doing an immediate WSAConnect() rather than an io completion port type for UDP. 2442. [bug] A lock could be destroyed twice. [RT# 18626] 2441. [bug] isc_radix_insert() could copy radix tree nodes incompletely. [RT #18573] 2440. [bug] named-checkconf used an incorrect test to determine if an ACL was set to none. 2439. [bug] Potential NULL dereference in dns_acl_isanyornone(). [RT #18559] 2438. [bug] Timeouts could be logged incorrectly under win32. 2437. [bug] Sockets could be closed too early, leading to inconsistent states in the socket module. [RT #18298] 2436. [security] win32: UDP client handler can be shutdown. [RT #18576] 2435. [bug] Fixed an ACL memory leak affecting win32. 2434. [bug] Fixed a minor error-reporting bug in lib/isc/win32/socket.c. 2433. [tuning] Set initial timeout to 800ms. 2432. [bug] More Windows socket handling improvements. Stop using I/O events and use IO Completion Ports throughout. Rewrite the receive path logic to make it easier to support multiple simultaneous requesters in the future. Add stricter consistency checking as a compile-time option (define ISC_SOCKET_CONSISTENCY_CHECKS; defaults to off). 2431. [bug] Acl processing could leak memory. [RT #18323] 2430. [bug] win32: isc_interval_set() could round down to zero if the input was less than NS_INTERVAL nanoseconds. Round up instead. [RT #18549] 2429. [doc] nsupdate should be in section 1 of the man pages. [RT #18283] 2428. [bug] dns_iptable_merge() mishandled merges of negative tables. [RT #18409] 2427. [func] Treat DNSKEY queries as if "minimal-response yes;" was set. [RT #18528] 2426. [bug] libbind: inet_net_pton() can sometimes return the wrong value if excessively large net masks are supplied. [RT #18512] 2425. [bug] named didn't detect unavailable query source addresses at load time. [RT #18536] 2424. [port] configure now probes for a working epoll implementation. Allow the use of kqueue, epoll and /dev/poll to be selected at compile time. [RT #18277] 2423. [security] Randomize server selection on queries, so as to make forgery a little more difficult. Instead of always preferring the server with the lowest RTT, pick a server with RTT within the same 128 millisecond band. [RT #18441] 2422. [bug] Handle the special return value of a empty node as if it was a NXRRSET in the validator. [RT #18447] 2421. [func] Add new command line option '-S' for named to specify the max number of sockets. [RT #18493] Use caution: this option may not work for some operating systems without rebuilding named. 2420. [bug] Windows socket handling cleanup. Let the io completion event send out canceled read/write done events, which keeps us from writing to memory we no longer have ownership of. Add debugging socket_log() function. Rework TCP socket handling to not leak sockets. 2419. [cleanup] Document that isc_socket_create() and isc_socket_open() should not be used for isc_sockettype_fdwatch sockets. [RT #18521] 2418. [bug] AXFR request on a DLZ could trigger a REQUIRE failure [RT #18430] 2417. [bug] Connecting UDP sockets for outgoing queries could unexpectedly fail with an 'address already in use' error. [RT #18411] 2416. [func] Log file descriptors that cause exceeding the internal maximum. [RT #18460] 2415. [bug] 'rndc dumpdb' could trigger various assertion failures in rbtdb.c. [RT #18455] 2414.

[bug] Fixed an unreachable code path in socket.c. [RT #18442] 2412. [bug] win32: address a resource leak. [RT #18374] 2411. [bug] Allow using a larger number of sockets than FD_SETSIZE for select(). To enable this, set ISC_SOCKET_MAXSOCKETS at compilation time. [RT #18433] Note: with changes #2469 and #2421 above, there is no need to tweak ISC_SOCKET_MAXSOCKETS at compilation time any more. 2410. [bug] Correctly delete m_versionInfo. [RT #18432] 2409. [bug] Only log that we disabled EDNS processing if we were subsequently successful. [RT #18029] 2408.

[bug] Multiple listen-on-v6 options with different ports were not accepted. [RT #1875] 1039. [bug] Negative responses with CNAMEs in the answer section were cached incorrectly. [RT #1862] 1038. [bug] In servers configured with a tkey-domain option, TKEY queries with an owner name other than the root could cause an assertion failure. [RT #1866, #1869] 1037. [bug] Negative responses whose authority section contain SOA or NS records whose owner names are not equal equal to or parents of the query name should be rejected. [RT #1862] 1036. [func] Silently drop requests received via multicast as long as there is no final multicast DNS standard. 1035. [bug] If we respond to multicast queries (which we currently do not), respond from a unicast address as specified in RFC 1123. [RT #137] 1034. [bug] Ignore the RD bit on multicast queries as specified in RFC 1123. [RT #137] 1033. [bug] Always respond to requests with an unsupported opcode with NOTIMP, even if we don't have a matching view or cannot determine the class. 1032. [func] hostname.bind/txt/chaos now returns the name of the machine hosting the nameserver. This is useful in diagnosing problems with anycast servers. 1031. [bug] libbind.a: isc__gettimeofday() infinite recursion. [RT #1858] 1030. [bug] On systems with no resolv.conf file, nsupdate exited with an error rather than defaulting to using the loopback address. [RT #1836] 1029. [bug] Some named.conf errors did not cause the loading of the configuration file to return a failure status even though they were logged. [RT #1847] 1028. [bug] On Win32, dig/host/nslookup looked for resolv.conf in the wrong directory. [RT #1833] 1027. [bug] RRs having the reserved type 0 should be rejected. [RT #1471] 1026. [placeholder] 1025. [bug] Don't use multicast addresses to resolve iterative queries. [RT #101] 1024. [port] Compilation failed on HP-UX 11.11 due to incompatible use of the SIOCGLIFCONF macro name. [RT #1831] 1023. [func] Accept hints without TTLs. 1022. [bug] Don't report empty root hints as "extra data". [RT #1802] 1021. [bug] On Win32, log message timestamps were one month later than they should have been, and the server would exhibit unspecified behavior in December. 1020. [bug] IXFR log messages did not distinguish between true IXFRs, AXFR-style IXFRs, and mere version polls. [RT #1811] 1019. [bug] The value of the lame-ttl option was limited to 18000 seconds, not 1800 seconds as documented. [RT #1803] 1018. [bug] The default log channel was not always initialized correctly. [RT #1813] 1017. [bug] When specifying TSIG keys to dig and nsupdate using the -k option, they must be HMAC-MD5 keys. [RT #1810] 1016. [bug] Slave zones with no backup file were re-transferred on every server reload. 1015. [bug] Log channels that had a "versions" option but no "size" option failed to create numbered log files. [RT #1783] 1014. [bug] Some queries would cause statistics counters to increment more than once or not at all. [RT #1321] 1013. [bug] It was possible to cancel a query twice when marking a server as bogus or by having a blackhole acl. [RT #1776] 1012. [bug] The -p option to named did not behave as documented. 1011. [cleanup] Removed isc_dir_current(). 1010. [bug] The server could attempt to execute a command channel command after initiating server shutdown, causing an assertion failure. [RT #1766] 1009. [port] OpenUNIX 8 support. [RT #1728] 1008. [port] libtool.m4, ltmain.sh from libtool-1.4.2. 1007. [port] config.guess, config.sub from autoconf-2.52. 1006. [bug] If a KEY RR was found missing during DNSSEC validation, an assertion failure could subsequently be triggered in the resolver. [RT #1763] 1005. [bug] Don't copy nonzero RCODEs from request to response. [RT #1765] 1004. [port] Deal with recvfrom() returning EHOSTDOWN. [RT #1770] 1003. [func] Add the +retry option to dig. 1002. [bug] When reporting an unknown class name in named.conf, including the file name and line number. [RT #1759] 1001. [bug] win32 socket code doio_recv was not catching a WSACONNRESET error when a client was timing out the request and closing its socket. [RT #1745] 1000. [bug] BIND 8 compatibility: accept "HESIOD" as an alias for class "HS". [RT #1759] 999. [func] "rndc retransfer zone [class [view]]" added. [RT #1752] 998. [func] named-checkzone now has arguments to specify the chroot directory (-t) and working directory (-w). [RT #1755] 997. [func] Add support for RSA-SHA1 keys (RFC3110). 996. [func] Issue warning if the configuration filename contains the chroot path. 995. [bug] dig, host, nslookup: using a raw IPv6 address as a target address should be fatal on a IPv4 only system. 994. [func] Treat non-authoritative responses to queries for type NS as referrals even if the NS records are in the answer section, because BIND 8 servers incorrectly send them that way. This is necessary for DNSSEC validation of the NS records of a secure zone to succeed when the parent is a BIND 8 server. [RT #1706] 993. [func] dig: -v now reports the version. 992. [doc] dig: ~/.digrc is now documented. 991. [func] Lower UDP refresh timeout messages to level debug 1. 990. [bug] The rndc-confgen man page was not installed. 989. [bug] Report filename if $INCLUDE fails for file related errors. [RT #1736] 988. [bug] 'additional-from-auth no;' did not work reliably in the case of queries answered from the cache. [RT #1436] 987. [bug] "dig -help" didn't show "+[no]stats". 986. [bug] "dig +noall" failed to clear stats and command printing. 985. [func] Consider network interfaces to be up iff they have a nonzero IP address rather than based on the IFF_UP flag. [RT #1160] 984. [bug] Multi-threading should be enabled by default on Solaris 2.7 and newer, but it wasn't. 983. [func] The server now supports generating IXFR difference sequences for non-dynamic zones by comparing zone versions, when enabled using the new config option "ixfr-from-differences". [RT #1727] 982. [func] If "memstatistics-file" is set in options the memory statistics will be written to it. 981. [func] The dnssec tools can now take multiple '-r randomfile' arguments. 980. [bug] Incoming zone transfers restarting after an error could trigger an assertion failure. [RT #1692] 979. [func] Incremental master file dumping. dns_master_dumpinc(), dns_master_dumptostreaminc(), dns_dumpctx_attach(), dns_dumpctx_detach(), dns_dumpctx_cancel(), dns_dumpctx_db() and dns_dumpctx_version(). 978. [bug] dns_db_attachversion() had an invalid REQUIRE() condition. 977. [bug] Improve "not at top of zone" error message. 976. [func] named-checkconf can now test load master zones (named-checkconf -z). [RT #1468] 975. [bug] "max-cache-size default;" as a view option caused an assertion failure. 974. [bug] "max-cache-size unlimited;" as a global option was not accepted. 973. [bug] Failed to log the question name when logging: "bad zone transfer request: non-authoritative zone (NOTAUTH)". 972. [bug] The file modification time code in zone.c was using the wrong epoch. [RT #1667] 971. [placeholder] 970. [func] 'max-journal-size' can now be used to set a target size for a journal. 969. [func] dig now supports the undocumented dig 8 feature of allowing arbitrary labels, not just dotted decimal quads, with the -x option. This can be used to conveniently look up RFC2317 names as in "dig -x 10.0.0.0-127". [RT #827, #1576, #1598] 968. [bug] On win32, the isc_time_now() function was unnecessarily calling strtime(). [RT #1671] 967. [bug] On win32, the link for bindevt was not including the required resource file to enable the event viewer to interpret the error messages in the event log, [RT #1668] 966. [placeholder] 965. [bug] Including data other than root server NS and A records in the root hint file could cause a rbtdb node reference leak. [RT #1581, #1618] 964. [func] Warn if data other than root server NS and A records are found in the root hint file. [RT #1581, #1618] 963. [bug] Bad ISC_LANG_ENDDECLS. [RT #1645] 962. [bug] libbind: bad "#undef", don't attempt to install non-existent nlist.h. [RT #1640] 961. [bug] Tried to use a IPV6 feature when ISC_PLATFORM_HAVEIPV6 was not defined. [RT #1482] 960. [port] liblwres failed to build on systems with support for getrrsetbyname() in the OS. [RT #1592] 959. [port] On FreeBSD, determine the number of CPUs by calling sysctlbyname(). [RT #1584] 958. [port] ssize_t is not available on all platforms. [RT #1607] 957. [bug] sys/select.h inclusion was broken on older platforms. [RT #1607] 956. [bug] ns_g_autorndcfile changed to ns_g_keyfile in named/win32/os.c due to code changes in change #953. win32 .make file for rndc-confgen updated to add include path for os.h header. --- 9.2.0rc1 released --- 955. [bug] When using views, the zone's class was not being inherited from the view's class. [RT #1583] 954. [bug] When requesting AXFRs or IXFRs using dig, host, or nslookup, the RD bit should not be set as zone transfers are inherently non-recursive. [RT #1575] 953. [func] The /var/run/named.key file from change #843 has been replaced by /etc/rndc.key. Both named and rndc will look for this file and use it to configure a default control channel key if not already configured using a different method (rndc.conf / controls). Unlike named.key, rndc.key is not created automatically; it must be created by manually running "rndc-confgen -a". 952. [bug] The server required manual intervention to serve the affected zones if it died between creating a journal and committing the first change to it. 951. [bug] CFLAGS was not passed to the linker when linking some of the test programs under bin/tests. [RT #1555]. 950. [bug] Explicit TTLs did not properly override $TTL due to a bug in change 834. [RT #1558] 949. [bug] host was unable to print records larger than 512 bytes. [RT #1557] --- 9.2.0b2 released --- 948. [port] Integrated support for building on Windows NT / Windows 2000. 947. [bug] dns_rdata_soa_t had a badly named element "mname" which was really the RNAME field from RFC1035. To avoid confusion and silent errors that would occur it the "origin" and "mname" elements were given their correct names "mname" and "rname" respectively, the "mname" element is renamed to "contact". 946. [cleanup] doc/misc/options is now machine-generated from the configuration parser syntax tables, and therefore more likely to be correct. 945. [func] Add the new view-specific options "match-destinations" and "match-recursive-only". 944. [func] Check for expired signatures on load. 943. [bug] The server could crash when receiving a command via rndc if the configuration file listed only nonexistent keys in the controls statement. [RT #1530] 942. [port] libbind: GETNETBYADDR_ADDR_T was not correctly defined on some platforms. 941. [bug] The configuration checker crashed if a slave zone didn't contain a masters statement. [RT #1514] 940. [bug] Double zone locking failure on error path. [RT #1510] --- 9.2.0b1 released --- 939. [port] Add the --disable-linux-caps option to configure for systems that manage capabilities outside of named. [RT #1503] 938. [placeholder] 937. [bug] A race when shutting down a zone could trigger a INSIST() failure. [RT #1034] 936. [func] Warn about IPv4 addresses that are not complete dotted quads. [RT #1084] 935. [bug] inet_pton failed to reject leading zeros. 934. [port] Deal with systems where accept() spuriously returns ECONNRESET. 933. [bug] configure failed doing libbind on platforms not supported by BIND 8. [RT #1496] --- 9.2.0a3 released --- 932. [bug] Use INSTALL_SCRIPT, not INSTALL_PROGRAM, when installing isc-config.sh. [RT #198, #1466] 931. [bug] The controls statement only attempted to verify messages using the first key in the key list. (9.2.0a1/a2 only). 930. [func] Query performance testing tool added as contrib/queryperf. 929. [placeholder] 928. [bug] nsupdate would send empty update packets if the send (or empty line) command was run after another send but before any new updates or prerequisites were specified. It should simply ignore this command. 927. [bug] Don't hold the zone lock for the entire dump to disk. [RT #1423] 926. [bug] The resolver could deadlock with the ADB when shutting down (multi-threaded builds only). [RT #1324] 925. [cleanup] Remove openssl from the distribution; require that --with-openssl be specified if DNSSEC is needed. 924. [port] Extend support for pre-RFC2133 IPv6 implementation. [RT #987] 923. [bug] Multiline TSIG secrets (and other multiline strings) were not accepted in named.conf. [RT #1469] 922. [func] Added two new lwres_getrrsetbyname() result codes, ERR_NONAME and ERR_NODATA. 921. [bug] lwres returned an incorrect error code if it received a truncated message. 920. [func] Increase the lwres receive buffer size to 16K. [RT #1451] 919. [placeholder] 918. [func] In nsupdate, TSIG errors are no longer treated as fatal errors. 917. [func] New nsupdate command 'key', allowing TSIG keys to be specified in the nsupdate command stream rather than the command line. 916. [bug] Specifying type ixfr to dig without specifying a serial number failed in unexpected ways. 915. [func] The named-checkconf and named-checkzone programs now have a '-v' option for printing their version. [RT #1151] 914. [bug] Global 'server' statements were rejected when using views, even though they were accepted in 9.1. [RT #1368] 913. [bug] Cache cleaning was not sufficiently aggressive. [RT #1441, #1444] 912. [bug] Attempts to set the 'additional-from-cache' or 'additional-from-auth' option to 'no' in a server with recursion enabled will now be ignored and cause a warning message. [RT #1145] 911. [placeholder] 910. [port] Some pre-RFC2133 IPv6 implementations do not define IN6ADDR_ANY_INIT. [RT #1416] 909. [placeholder] 908. [func] New program, rndc-confgen, to simplify setting up rndc. 907. [func] The ability to get entropy from either the random device, a user-provided file or from the keyboard was migrated from the DNSSEC tools to libisc as isc_entropy_usebestsource(). 906. [port] Separated the system independent portion of lib/isc/unix/entropy.c into lib/isc/entropy.c and added lib/isc/win32/entropy.c. 905. [bug] Configuring a forward "zone" for the root domain did not work. [RT #1418] 904. [bug] The server would leak memory if attempting to use an expired TSIG key. [RT #1406] 903. [bug] dig should not crash when receiving a TCP packet of length 0. 902. [bug] The -d option was ignored if both -t and -g were also specified. 901. [placeholder] 900. [bug] A config.guess update changed the system identification string of FreeBSD systems; configure and bin/tests/system/ifconfig.sh now recognize the new string. --- 9.2.0a2 released --- 899. [bug] lib/dns/soa.c failed to compile on many platforms due to inappropriate use of a void value. [RT #1372, #1373, #1386, #1387, #1395] 898. [bug] "dig" failed to set a nonzero exit status on UDP query timeout. [RT #1323] 897. [bug] A config.guess update changed the system identification string of UnixWare systems; configure now recognizes the new string. 896. [bug] If a configuration file is set on named's command line and it has a relative pathname, the current directory (after any possible jailing resulting from named -t) will be prepended to it so that reloading works properly even when a directory option is present. 895. [func] New function, isc_dir_current(), akin to POSIX's getcwd(). 894. [bug] When using the DNSSEC tools, a message intended to warn when the keyboard was being used because of the lack of a suitable random device was not being printed. 893. [func] Removed isc_file_test() and added isc_file_exists() for the basic functionality that was being added with isc_file_test(). 892. [placeholder] 891. [bug] Return an error when a SIG(0) signed response to an unsigned query is seen. This should actually do the verification, but it's not currently possible. [RT #1391] 890. [cleanup] The man pages no longer require the mandoc macros and should now format cleanly using most versions of nroff, and HTML versions of the man pages have been added. Both are generated from DocBook source. 889. [port] Eliminated blank lines before .TH in nroff man pages since they cause problems with some versions of nroff. [RT #1390] 888. [bug] Don't die when using TKEY to delete a nonexistent TSIG key. [RT #1392] 887. [port] Detect broken compilers that can't call static functions from inline functions. [RT #1212] 886. [placeholder] 885. [placeholder] 884. [placeholder] 883. [placeholder] 882. [placeholder] 881. [placeholder] 880. [placeholder] 879. [placeholder] 878. [placeholder] 877. [placeholder] 876. [placeholder] 875. [placeholder] 874. [placeholder] 873. [placeholder] 872. [placeholder] 871. [placeholder] 870. [placeholder] 869. [placeholder] 868. [placeholder] 867. [placeholder] 866. [func] Close debug only file channels when debug is set to zero. [RT #1246] 865. [bug] The new configuration parser did not allow the optional debug level in a "severity debug" clause of a logging channel to be omitted. This is now allowed and treated as "severity debug 1;" like it does in BIND 8.2.4, not as "severity debug 0;" like it did in BIND 9.1. [RT #1367] 864. [cleanup] Multi-threading is now enabled by default on OSF1, Solaris 2.7 and newer, AIX, IRIX, and HP-UX. 863. [bug] If an error occurred while an outgoing zone transfer was starting up, the server could access a domain name that had already been freed when logging a message saying that the transfer was starting. [RT #1383] 862. [bug] Use after realloc(), non portable pointer arithmetic in grmerge(). 861. [port] Add support for Mac OS X, by making it equivalent to Darwin. This was derived from the config.guess file shipped with Mac OS X. [RT #1355] 860. [func] Drop cross class glue in zone transfers. 859. [bug] Cache cleaning now won't swamp the CPU if there is a persistent over limit condition. 858. [func] isc_mem_setwater() no longer requires that when the callback function is non-NULL then its hi_water argument must be greater than its lo_water argument (they can now be equal) or that they be non-zero. 857. [cleanup] Use ISC_MAGIC() to define all magic numbers for structs, for our friends in EBCDIC-land. 856. [func] Allow partial rdatasets to be returned in answer and authority sections to help non-TCP capable clients recover from truncation. [RT #1301] 855. [bug] Stop spurious "using RFC 1035 TTL semantics" warnings. 854. [bug] The config parser didn't properly handle config options that were specified in units of time other than seconds. [RT #1372] 853. [bug] configure_view_acl() failed to detach existing acls. [RT #1374] 852. [bug] Handle responses from servers which do not know about IXFR. 851. [cleanup] The obsolete support-ixfr option was not properly ignored. --- 9.2.0a1 released --- 850. [bug] dns_rbt_findnode() would not find nodes that were split on a bitstring label somewhere other than in the last label of the node. [RT #1351] 849. [func] will ensure INADDR_LOOPBACK is defined. 848. [func] A minimum max-cache-size of two megabytes is enforced by the cache cleaner. 847. [func] Added isc_file_test(), which currently only has some very basic functionality to test for the existence of a file, whether a pathname is absolute, or whether a pathname is the fundamental representation of the current directory. It is intended that this function can be expanded to test other things a programmer might want to know about a file. 846. [func] A non-zero 'param' to dst_key_generate() when making an hmac-md5 key means that good entropy is not required. 845. [bug] The access rights on the public file of a symmetric key are now restricted as soon as the file is opened, rather than after it has been written and closed. 844. [func] will ensure INADDR_LOOPBACK is defined, just as does. 843. [func] If no controls statement is present in named.conf, or if any inet phrase of a controls statement is lacking a keys clause, then a key will be automatically generated by named and an rndc.conf-style file named named.key will be written that uses it. rndc will use this file only if its normal configuration file, or one provided on the command line, does not exist. 842. [func] 'rndc flush' now takes an optional view. 841. [bug] When sdb modules were not declared threadsafe, their create and destroy functions were not serialized. 840. [bug] The config file parser could print the wrong file name if an error was detected after an included file was parsed. [RT #1353] 839. [func] Dump packets for which there was no view or that the class could not be determined to category "unmatched". 838. [port] UnixWare 7.x.x is now suported by bin/tests/system/ifconfig.sh. 837. [cleanup] Multi-threading is now enabled by default only on OSF1, Solaris 2.7 and newer, and AIX. 836. [func] Upgraded libtool to 1.4. 835. [bug] The dispatcher could enter a busy loop if it got an I/O error receiving on a UDP socket. [RT #1293] 834. [func] Accept (but warn about) master files beginning with an SOA record without an explicit TTL field and lacking a $TTL directive, by using the SOA MINTTL as a default TTL. This is for backwards compatibility with old versions of BIND 8, which accepted such files without warning although they are illegal according to RFC1035. 833. [cleanup] Moved dns_soa_*() from to , and extended them to support all the integer-valued fields of the SOA RR. 832. [bug] The default location for named.conf in named-checkconf should depend on --sysconfdir like it does in named. [RT #1258] 831. [placeholder] 830. [func] Implement 'rndc status'. 829. [bug] The DNS_R_ZONECUT result code should only be returned when an ANY query is made with DNS_DBFIND_GLUEOK set. In all other ANY query cases, returning the delegation is better. 828. [bug] The errno value from recvfrom() could be overwritten by logging code. [RT #1293] 827. [bug] When an IXFR protocol error occurs, the slave should retry with AXFR. 826. [bug] Some IXFR protocol errors were not detected. 825. [bug] zone.c:ns_query() detached from the wrong zone reference. [RT #1264] 824. [bug] Correct line numbers reported by dns_master_load(). [RT #1263] 823. [func] The output of "dig -h" now goes to stdout so that it can easily be piped through "more". [RT #1254] 822. [bug] Sending nxrrset prerequisites would crash nsupdate. [RT #1248] 821. [bug] The program name used when logging to syslog should be stripped of leading path components. [RT #1178, #1232] 820. [bug] Name server address lookups failed to follow A6 chains into the glue of local authoritative zones. 819. [bug] In certain cases, the resolver's attempts to restart an address lookup at the root could cause the fetch to deadlock (with itself) instead of restarting. [RT #1225] 818. [bug] Certain pathological responses to ANY queries could cause an assertion failure. [RT #1218] 817. [func] Adjust timeouts for dialup zone queries. 816. [bug] Report potential problems with log file accessibility at configuration time, since such problems can't reliably be reported at the time they actually occur. 815. [bug] If a log file was specified with a path separator character (i.e. "/") in its name and the directory did not exist, the log file's name was treated as though it were the directory name. [RT #1189] 814. [bug] Socket objects left over from accept() failures were incorrectly destroyed, causing corruption of socket manager data structures. 813. [bug] File descriptors exceeding FD_SETSIZE were handled badly. [RT #1192] 812. [bug] dig sometimes printed incomplete IXFR responses due to an uninitialized variable. [RT #1188] 811. [bug] Parentheses were not quoted in zone dumps. [RT #1194] 810. [bug] The signer name in SIG records was not properly down-cased when signing/verifying records. [RT #1186] 809. [bug] Configuring a non-local address as a transfer-source could cause an assertion failure during load. 808. [func] Add 'rndc flush' to flush the server's cache. 807. [bug] When setting up TCP connections for incoming zone transfers, the transfer-source port was not ignored like it should be. 806. [bug] DNS_R_SEENINCLUDE was failing to propagate back up the calling stack to the zone maintenance level, causing zones to not reload when an included file was touched but the top-level zone file was not. 805. [bug] When using "forward only", missing root hints should not cause queries to fail. [RT #1143] 804. [bug] Attempting to obtain entropy could fail in some situations. This would be most common on systems with user-space threads. [RT #1131] 803. [bug] Treat all SIG queries as if they have the CD bit set, otherwise no data will be returned [RT #749] 802. [bug] DNSSEC key tags were computed incorrectly in almost all cases. [RT #1146] 801. [bug] nsupdate should treat lines beginning with ';' as comments. [RT #1139] 800. [bug] dnssec-signzone produced incorrect statistics for large zones. [RT #1133] 799. [bug] The ADB didn't find AAAA glue in a zone unless A6 glue was also present. 798. [bug] nsupdate should be able to reject bad input lines and continue. [RT #1130] 797. [func] Issue a warning if the 'directory' option contains a relative path. [RT #269] 796.

[bug] The command channel now works over IPv6. 790. [bug] Wildcards created using dynamic update or IXFR could fail to match. [RT #1111] 789. [bug] The "localhost" and "localnets" ACLs did not match when used as the second element of a two-element sortlist item. 788. [func] Add the "match-mapped-addresses" option, which causes IPv6 v4mapped addresses to be treated as IPv4 addresses for the purpose of acl matching. 787. [bug] The DNSSEC tools failed to downcase domain names when mapping them into file names. 786. [bug] When DNSSEC signing/verifying data, owner names were not properly down-cased. 785.

[func] Avoid error packet loops by dropping duplicate FORMERR responses. [RT #1006] 780. [bug] Error handling code dealing with out of memory or other rare errors could lead to assertion failures by calling functions on uninitialized names. [RT #1065] 779. [func] Added the "minimal-responses" option. 778. [bug] When starting cache cleaning, cleaning_timer_action() returned without first pausing the iterator, which could cause deadlock. [RT #998] 777.

[bug] The server did not emit an SOA when a CNAME or DNAME chain ended in NXDOMAIN in an authoritative zone. 767. [placeholder] 766. [bug] A few cases in query_find() could leak fname. This would trigger the mpctx->allocated == 0 assertion when the server exited. [RT #739, #776, #798, #812, #818, #821, #845, #892, #935, #966] 765. [func] ACL names are once again case insensitive, like in BIND 8. [RT #252] 764. [func] Configuration files now allow "include" directives in more places, such as inside the "view" statement. [RT #377, #728, #860] 763. [func] Configuration files no longer have reserved words. [RT #731, #753] 762. [cleanup] The named.conf and rndc.conf file parsers have been completely rewritten. 761. [bug] _REENTRANT was still defined when building with --disable-threads. 760. [contrib] Significant enhancements to the pgsql sdb driver. 759. [bug] The resolver didn't turn off "avoid fetches" mode when restarting, possibly causing resolution to fail when it should not. This bug only affected platforms which support both IPv4 and IPv6. [RT #927] 758. [bug] The "avoid fetches" code did not treat negative cache entries correctly, causing fetches that would be useful to be avoided. This bug only affected platforms which support both IPv4 and IPv6. [RT #927] 757. [func] Log zone transfers. 756. [bug] dns_zone_load() could "return" success when no master file was configured. 755. [bug] Fix incorrectly formatted log messages in zone.c. 754. [bug] Certain failure conditions sending UDP packets could cause the server to retry the transmission indefinitely. [RT #902] 753.

[func] Correct bad tv_usec elements returned by gettimeofday(). 751. [func] Log successful zone loads / transfers. [RT #898] 750. [bug] A query should not match a DNAME whose trust level is pending. [RT #916] 749. [bug] When a query matched a DNAME in a secure zone, the server did not return the signature of the DNAME. [RT #915] 748. [doc] List supported RFCs in doc/misc/rfc-compliance. [RT #781] 747. [bug] The code to determine whether an IXFR was possible did not properly check for a database that could not have a journal. [RT #865, #908] 746. [bug] The sdb didn't clone rdatasets properly, causing a crash when the server followed delegations. [RT #905] 745. [func] Report the owner name of records that fail semantic checks while loading. 744. [bug] When returning DNS_R_CNAME or DNS_R_DNAME as the result of an ANY or SIG query, the resolver failed to setup the return event's rdatasets, causing an assertion failure in the query code. [RT #881] 743. [bug] Receiving a large number of certain malformed answers could cause named to stop responding. [RT #861] 742. [placeholder] 741. [port] Support openssl-engine. [RT #709] 740. [port] Handle openssl library mismatches slightly better. 739. [port] Look for /dev/random in configure, rather than assuming it will be there for only a predefined set of OSes. 738. [bug] If a non-threadsafe sdb driver supported AXFR and received an AXFR request, it would deadlock or die with an assertion failure. [RT #852] 737.

[func] The forwarders statement now takes an optional port. [RT #418] 709. [bug] ANY or SIG queries for data with a TTL of 0 would return SERVFAIL. [RT #620] 708. [bug] When building with --with-openssl, the openssl headers included with BIND 9 should not be used. [RT #702] 707. [func] The "filename" argument to named-checkzone is no longer optional, to reduce confusion. [RT #612] 706. [bug] Zones with an explicit "allow-update { none; };" were considered dynamic and therefore not reloaded on SIGHUP or "rndc reload". 705. [port] Work out resource limit type for use where rlim_t is not available. [RT #695] 704. [port] RLIMIT_NOFILE is not available on all platforms. [RT #695] 703. [port] sys/select.h is needed on older platforms. [RT #695] 702. [func] If the address 0.0.0.0 is seen in resolv.conf, use 127.0.0.1 instead. [RT #693] 701. [func] Root hints are now fully optional. Class IN views use compiled-in hints by default, as before. Non-IN views with no root hints now provide authoritative service but not recursion. A warning is logged if a view has neither root hints nor authoritative data for the root. [RT #696] 700. [bug] $GENERATE range check was wrong. [RT #688] 699. [bug] The lexer mishandled empty quoted strings. [RT #694] 698. [bug] Aborting nsupdate with ^C would lead to several race conditions. 697. [bug] nsupdate was not compatible with the undocumented BIND 8 behavior of ignoring TTLs in "update delete" commands. [RT #693] 696. [bug] lwresd would die with an assertion failure when passed a zero-length name. [RT #692] 695. [bug] If the resolver attempted to query a blackholed or bogus server, the resolution would fail immediately. 694. [bug] $GENERATE did not produce the last entry. [RT #682, #683] 693.

[bug] dnssec-signzone would occasionally use the wrong ttl for database operations and fail. [RT #643] 676. [bug] Log messages about lame servers to category 'lame-servers' rather than 'resolver', so as not to be gratuitously incompatible with BIND 8. 675. [bug] TKEY queries could cause the server to leak memory. 674. [func] Allow messages to be TSIG signed / verified using a offset from the current time. 673. [func] The server can now convert RFC1886-style recursive lookup requests into RFC2874-style lookups, when enabled using the new option "allow-v6-synthesis". 672. [bug] The wrong time was in the "time signed" field when replying with BADTIME error. 671. [bug] The message code was failing to parse a message with no question section and a TSIG record. [RT #628] 670. [bug] The lwres replacements for getaddrinfo and getipnodebyname didn't properly check for the existence of the sockaddr sa_len field. 669. [bug] dnssec-keygen now makes the public key file non-world-readable for symmetric keys. [RT #403] 668. [func] named-checkzone now reports multiple errors in master files. 667. [bug] On Linux, running named with the -u option and a non-world-readable configuration file didn't work. [RT #626] 666. [bug] If a request sent by dig is longer than 512 bytes, use TCP. 665. [bug] Signed responses were not sent when the size of the TSIG + question exceeded the maximum message size. [RT #628] 664. [bug] The t_tasks and t_timers module tests are now skipped when building without threads, since they require threads. 663. [func] Accept a size_spec, not just an integer, in the (unimplemented and ignored) max-ixfr-log-size option for compatibility with recent versions of BIND 8. [RT #613] 662. [bug] dns_rdata_fromtext() failed to log certain errors. 661. [bug] Certain UDP IXFR requests caused an assertion failure (mpctx->allocated == 0). [RT #355, #394, #623] 660.

[bug] Improve error reporting on unexpected eof when loading zones. [RT #611] 654. [bug] Origin was being forgotten in TCP retries in dig. [RT #574] 653. [bug] +defname option in dig was reversed in sense. [RT #549] 652. [bug] zone_saveunique() did not report the new name. 651. [func] The AD bit in responses now has the meaning specified in . 650. [bug] SIG(0) records were being generated and verified incorrectly. [RT #606] 649. [bug] It was possible to join to an already running fctx after it had "cloned" its events, but before it sent them. In this case, the event of the newly joined fetch would not contain the answer, and would trigger the INSIST() in fctx_sendevents(). In BIND 9.0, this bug did not trigger an INSIST(), but caused the fetch to fail with a SERVFAIL result. [RT #588, #597, #605, #607] 648. [port] Add support for pre-RFC2133 IPv6 implementations. 647. [bug] Resolver queries sent after following multiple referrals had excessively long retransmission timeouts due to incorrectly counting the referrals as "restarts". 646.

[RT #584] 639. [bug] Reading entropy from the keyboard would sometimes fail. [RT #591] 638. [port] lib/isc/random.c needed to explicitly include time.h to get a prototype for time() when pthreads was not being used. [RT #592] 637. [port] Use isc_u?int64_t instead of (unsigned) long long in lib/isc/print.c. Also allow lib/isc/print.c to be compiled even if the platform does not need it. [RT #592] 636.

[bug] 9.1.0b1 dereferenced a null pointer and crashed when responding to a UDP IXFR request. 628. [bug] If the root hints contained only AAAA addresses, named would be unable to perform resolution. 627. [bug] The EDNS0 blackhole detection code of change 324 waited for three retransmissions to each server, which takes much too long when a domain has many name servers and all of them drop EDNS0 queries. Now we retry without EDNS0 after three consecutive timeouts, even if they are all from different servers. [RT #143] 626. [bug] The lightweight resolver daemon no longer crashes when asked for a SIG rrset. [RT #558] 625. [func] Zones now inherit their class from the enclosing view. 624. [bug] The zone object could get timer events after it had been destroyed, causing a server crash. [RT #571] 623. [func] Added "named-checkconf" and "named-checkzone" program for syntax checking named.conf files and zone files, respectively. 622. [bug] A canceled request could be destroyed before dns_request_destroy() was called. [RT #562] 621. [port] Disable IPv6 at runtime if IPv6 sockets are unusable.

Also 'done' will not be called if dns_master_load*inc() fails immediately. [RT #565] 619. [placeholder] 618. [bug] Queries to a signed zone could sometimes cause an assertion failure. 617. [bug] When using dynamic update to add a new RR to an existing RRset with a different TTL, the journal entries generated from the update did not include explicit deletions and re-additions of the existing RRs to update their TTL to the new value. 616. [func] dnssec-signzone -t output now includes performance statistics. 615. [bug] dnssec-signzone did not like child keysets signed by multiple keys. 614. [bug] Checks for uninitialized link fields were prone to false positives, causing assertion failures. The checks are now disabled by default and may be re-enabled by defining ISC_LIST_CHECKINIT. 613. [bug] "rndc reload zone" now reloads primary zones. It previously only updated slave and stub zones, if an SOA query indicated an out of date serial. 612. [cleanup] Shutup a ridiculously noisy HP-UX compiler that complains relentlessly about how its treatment of 'const' has changed as well as how casting sometimes tightens alignment constraints. 611. [func] allow-notify can be used to permit processing of notify messages from hosts other than a slave's masters. 610. [func] rndc dumpdb is now supported. 609.

[bug] If a secure zone was missing all its NXTs and a dynamic update was attempted, the server entered an infinite loop. 592. [bug] The sig-validity-interval option now specifies a number of days, not seconds. This matches the documentation. [RT #529] --- 9.1.0b1 released --- 591. [bug] Work around non-reentrancy in openssl by disabling pre-computation in keys. 590. [doc] There are now man pages for the lwres library in doc/man/lwres. 589. [bug] The server could deadlock if a zone was updated while being transferred out. 588. [bug] ctx->in_use was not being correctly initialized when when pushing a file for $INCLUDE. [RT #523] 587. [func] A warning is now printed if the "allow-update" option allows updates based on the source IP address, to alert users to the fact that this is insecure and becoming increasingly so as servers capable of update forwarding are being deployed. 586. [bug] multiple views with the same name were fatal. [RT #516] 585. [func] dns_db_addrdataset() and and dns_rdataslab_merge() now support 'exact' additions in a similar manner to dns_db_subtractrdataset() and dns_rdataslab_subtract(). 584. [func] You can now say 'notify explicit'; to suppress notification of the servers listed in NS records and notify only those servers listed in the 'also-notify' option. 583.

[func] Log illegal RDATA combinations. e.g. multiple singleton types, cname and other data. 576. [doc] isc_log_create() description did not match reality. 575. [bug] isc_log_create() was not setting internal state correctly to reflect the default channels created. 574. [bug] TSIG signed queries sent by the resolver would fail to have their responses validated and would leak memory. 573. [bug] The journal files of IXFRed slave zones were inadvertently discarded on server reload, causing "journal out of sync with zone" errors on subsequent reloads. [RT #482] 572. [bug] Quoted strings were not accepted as key names in address match lists. 571. [bug] It was possible to create an rdataset of singleton type which had more than one rdata. [RT #154] [RT #279] 570.

[bug] In some cases, not all of the dnssec tools were properly installed. 553. [bug] Incoming zone transfers deferred due to quota were not started when quota was increased but only when a transfer in progress finished. [RT #456] 552.

[func] Add statistics option, enable statistics-file option, add RNDC option "dump-statistics" to write out a query statistics file. 543. [doc] The 'port' option is now documented. 542. [func] Add support for update forwarding as required for full compliance with RFC2136. It is turned off by default and can be enabled using the 'allow-update-forwarding' option. 541. [func] Add bogus server support. 540. [func] Add dialup support. 539. [func] Support the blackhole option. 538. [bug] fix buffer overruns by 1 in lwres_getnameinfo(). 537. [placeholder] 536. [func] Use transfer-source{-v6} when sending refresh queries. Transfer-source{-v6} now take a optional port parameter for setting the UDP source port. The port parameter is ignored for TCP. 535. [func] Use transfer-source{-v6} when forwarding update requests. 534. [func] Ancestors have been removed from RBT chains. Ancestor information can be discerned via node parent pointers. 533. [func] Incorporated name hashing into the RBT database to improve search speed. 532. [func] Implement DNS UPDATE pseudo records using DNS_RDATA_UPDATE flag. 531. [func] Rdata really should be initialized before being assigned to (dns_rdata_fromwire(), dns_rdata_fromtext(), dns_rdata_clone(), dns_rdata_fromregion()), check that it is. 530. [func] New function dns_rdata_invalidate(). 529. [bug] 521 contained a bug which caused zones to always reload. [RT #410] 528. [func] The ISC_LIST_XXXX macros now perform sanity checks on their arguments. ISC_LIST_XXXXUNSAFE can be use to skip the checks however use with caution. 527. [func] New function dns_rdata_clone(). 526. [bug] nsupdate incorrectly refused to add RRs with a TTL of 0. 525. [func] New arguments 'options' for dns_db_subtractrdataset(), and 'flags' for dns_rdataslab_subtract() allowing you to request that the RR's must exist prior to deletion. DNS_R_NOTEXACT is returned if the condition is not met. 524. [func] The 'forward' and 'forwarders' statement in non-forward zones should work now. 523. [doc] The source to the Administrator Reference Manual is now an XML file using the DocBook DTD, and is included in the distribution. The plain text version of the ARM is temporarily unavailable while we figure out how to generate readable plain text from the XML. 522. [func] The lightweight resolver daemon can now use a real configuration file, and its functionality can be provided by a name server. Also, the -p and -P options to lwresd have been reversed. 521. [bug] Detect master files which contain $INCLUDE and always reload. [RT #196] 520. [bug] Upgraded libtool to 1.3.5, which makes shared library builds almost work on AIX (and possibly others). 519. [bug] dns_name_split() would improperly split some bitstring labels, zeroing a few of the least significant bits in the prefix part. When such an improperly created prefix was returned to the RBT database, the bogus label was dutifully stored, corrupting the tree. [RT #369] 518. [bug] The resolver did not realize that a DNAME which was "the answer" to the client's query was "the answer", and such queries would fail. [RT #399] 517. [bug] The resolver's DNAME code would trigger an assertion if there was more than one DNAME in the chain. [RT #399] 516. [bug] Cache lookups which had a NULL node pointer, e.g. those by dns_view_find(), and which would match a DNAME, would trigger an INSIST(!search.need_cleanup) assertion. [RT #399] 515. [bug] The ssu table was not being attached / detached by dns_zone_[sg]etssutable. [RT#397] 514. [func] Retry refresh and notify queries if they timeout. [RT #388] 513. [func] New functionality added to rdnc and server to allow individual zones to be refreshed or reloaded. 512. [bug] The zone transfer code could throw an exception with an invalid IXFR stream. 511. [bug] The message code could throw an assertion on an out of memory failure. [RT #392] 510. [bug] Remove spurious view notify warning. [RT #376] 509. [func] Add support for write of zone files on shutdown. 508. [func] dns_message_parse() can now do a best-effort attempt, which should allow dig to print more invalid messages. 507. [func] New functions dns_zone_flush(), dns_zt_flushanddetach() and dns_view_flushanddetach(). 506. [func] Do not fail to start on errors in zone files. 505. [bug] nsupdate was printing "unknown result code". [RT #373] 504. [bug] The zone was not being marked as dirty when updated via IXFR. 503. [bug] dumptime was not being set along with DNS_ZONEFLG_NEEDDUMP. 502. [func] On a SERVFAIL reply, DiG will now try the next server in the list, unless the +fail option is specified. 501. [bug] Incorrect port numbers were being displayed by nslookup. [RT #352] 500. [func] Nearly useless +details option removed from DiG. 499. [func] In DiG, specifying a class with -c or type with -t changes command-line parsing so that classes and types are only recognized if following -c or -t. This allows hosts with the same name as a class or type to be looked up. 498. [doc] There is now a man page for "dig" in doc/man/bin/dig.1. 497. [bug] The error messages printed when an IP match list contained a network address with a nonzero host part where not sufficiently detailed. [RT #365] 496. [bug] named didn't sanity check numeric parameters. [RT #361] 495. [bug] nsupdate was unable to handle large records. [RT #368] 494. [func] Do not cache NXDOMAIN responses for SOA queries. 493. [func] Return non-cachable (ttl = 0) NXDOMAIN responses for SOA queries. This makes it easier to locate the containing zone without polluting intermediate caches. 492. [bug] attempting to reload a zone caused the server fail to shutdown cleanly. [RT #360] 491. [bug] nsupdate would segfault when sending certain prerequisites with empty RDATA. [RT #356] 490. [func] When a slave/stub zone has not yet successfully obtained an SOA containing the zone's configured retry time, perform the SOA query retries using exponential backoff. [RT #337] 489. [func] The zone manager now has a "i/o" queue. 488. [bug] Locks weren't properly destroyed in some cases. 487. [port] flockfile() is not defined on all systems. 486. [bug] nslookup: "set all" and "server" commands showed the incorrect port number if a port other than 53 was specified. [RT #352] 485. [func] When dig had more than one server to query, it would send all of the messages at the same time. Add rate limiting of the transmitted messages. 484. [bug] When the server was reloaded after removing addresses from the named.conf "listen-on" statement, sockets were still listening on the removed addresses due to reference count loops. [RT #325] 483. [bug] nslookup: "set all" showed a "search" option but it was not settable. 482. [bug] nslookup: a plain "server" or "lserver" should be treated as a lookup. 481. [bug] nslookup:get_next_command() stack size could exceed per thread limit. 480. [bug] strtok() is not thread safe. [RT #349] 479. [func] The test suite can now be run by typing "make check" or "make test" at the top level. 478. [bug] "make install" failed if the directory specified with --prefix did not already exist. 477. [bug] The the isc-config.sh script could be installed before its directory was created. [RT #324] 476. [bug] A zone could expire while a zone transfer was in progress triggering a INSIST failure. [RT #329] 475. [bug] query_getzonedb() sometimes returned a non-null version on failure. This caused assertion failures when generating query responses where names subject to additional section processing pointed to a zone to which access had been denied by means of the allow-query option. [RT #336] 474. [bug] The mnemonic of the CHAOS class is CH according to RFC1035, but it was printed and read only as CHAOS. We now accept both forms as input, and print it as CH. [RT #305] 473. [bug] nsupdate overran the end of the list of name servers when no servers could be reached, typically causing it to print the error message "dns_request_create: not implemented". 472. [bug] Off-by-one error caused isc_time_add() to sometimes produce invalid time values. 471. [bug] nsupdate didn't compile on HP/UX 10.20 470. [func] $GENERATE is now supported. See also doc/misc/migration. 469. [bug] "query-source address * port 53;" now works. 468. [bug] dns_master_load*() failed to report file and line number in certain error conditions. 467. [bug] dns_master_load*() failed to log an error if pushfile() failed. 466. [bug] dns_master_load*() could return success when it failed. 465. [cleanup] Allow 0 to be set as an omapi_value_t value by omapi_value_storeint(). 464. [cleanup] Build with openssl's RSA code instead of dnssafe. 463. [bug] nsupdate sent malformed SOA queries to the second and subsequent name servers in resolv.conf if the query sent to the first one failed. 462. [bug] --disable-ipv6 should work now. 461. [bug] Specifying an unknown key in the "keys" clause of the "controls" statement caused a NULL pointer dereference. [RT #316] 460. [bug] Much of the DNSSEC code only worked with class IN. 459. [bug] Nslookup processed the "set" command incorrectly. 458. [bug] Nslookup didn't properly check class and type values. [RT #305] 457. [bug] Dig/host/hslookup didn't properly handle connect timeouts in certain situations, causing an unnecessary warning message to be printed. 456. [bug] Stub zones were not resetting the refresh and expire counters, loadtime or clearing the DNS_ZONE_REFRESH (refresh in progress) flag upon successful update. This disabled further refreshing of the stub zone, causing it to eventually expire. [RT #300] 455. [doc] Document IPv4 prefix notation does not require a dotted decimal quad but may be just dotted decimal. 454. [bug] Enforce dotted decimal and dotted decimal quad where documented as such in named.conf. [RT #304, RT #311] 453. [bug] Warn if the obsolete option "maintain-ixfr-base" is specified in named.conf. [RT #306] 452. [bug] Warn if the unimplemented option "statistics-file" is specified in named.conf. [RT #301] 451. [func] Update forwarding implemented. 450. [func] New function ns_client_sendraw(). 449. [bug] isc_bitstring_copy() only works correctly if the two bitstrings have the same lsb0 value, but this requirement was not documented, nor was there a REQUIRE for it. 448. [bug] Host output formatting change, to match v8. [RT #255] 447. [bug] Dig didn't properly retry in TCP mode after a truncated reply. [RT #277] 446. [bug] Confusing notify log message. [RT #298] 445. [bug] Doing a 0 bit isc_bitstring_copy() of an lsb0 bitstring triggered a REQUIRE statement. The REQUIRE statement was incorrect. [RT #297] 444. [func] "recursion denied" messages are always logged at debug level 1, now, rather than sometimes at ERROR. This silences these warnings in the usual case, where some clients set the RD bit in all queries. 443. [bug] When loading a master file failed because of an unrecognized RR type name, the error message did not include the file name and line number. [RT #285] 442. [bug] TSIG signed messages that did not match any view crashed the server. [RT #290] 441. [bug] Nodes obscured by a DNAME were inaccessible even when DNS_DBFIND_GLUEOK was set. 440. [func] New function dns_zone_forwardupdate(). 439. [func] New function dns_request_createraw(). 438. [func] New function dns_message_getrawmessage(). 437. [func] Log NOTIFY activity to the notify channel. 436. [bug] If recvmsg() returned EHOSTUNREACH or ENETUNREACH, which sometimes happens on Linux, named would enter a busy loop. Also, unexpected socket errors were not logged at a high enough logging level to be useful in diagnosing this situation. [RT #275] 435. [bug] dns_zone_dump() overwrote existing zone files rather than writing to a temporary file and renaming. This could lead to empty or partial zone files being left around in certain error conditions involving the initial transfer of a slave zone, interfering with subsequent server startup. [RT #282] 434. [func] New function isc_file_isabsolute(). 433. [func] isc_base64_decodestring() now accepts newlines within the base64 data. This makes it possible to break up the key data in a "trusted-keys" statement into multiple lines. [RT #284] 432. [func] Added refresh/retry jitter. The actual refresh/ retry time is now a random value between 75% and 100% of the configured value. 431. [func] Log at ISC_LOG_INFO when a zone is successfully loaded. 430. [bug] Rewrote the lightweight resolver client management code to handle shutdown correctly and general cleanup. 429. [bug] The space reserved for a TSIG record in a response was 2 bytes too short, leading to message generation failures. 428. [bug] rbtdb.c:find_closest_nxt() erroneously returned DNS_R_BADDB for nodes which had neither NXT nor SIG NXT (e.g. glue). This could cause SERVFAILs when generating negative responses in a secure zone. 427. [bug] Avoid going into an infinite loop when the validator gets a negative response to a key query where the records are signed by the missing key. 426. [bug] Attempting to generate an oversized RSA key could cause dnssec-keygen to dump core. 425. [bug] Warn about the auth-nxdomain default value change if there is no auth-nxdomain statement in the config file. [RT #287] 424. [bug] notify_createmessage() could trigger an assertion failure when creating the notify message failed, e.g. due to corrupt zones with multiple SOA records. [RT #279] 423. [bug] When responding to a recursive query, errors that occur after following a CNAME should cause the query to fail. [RT #274] 422. [func] get rid of isc_random_t, and make isc_random_get() and isc_random_jitter() use rand() internally instead of local state. Note that isc_random_*() functions are only for weak, non-critical "randomness" such as timing jitter and such. 421. [bug] nslookup would exit when given a blank line as input. 420. [bug] nslookup failed to implement the "exit" command. 419. [bug] The certificate type PKIX was misspelled as SKIX. 418. [bug] At debug levels >= 10, getting an unexpected socket receive error would crash the server while trying to log the error message. 417. [func] Add isc_app_block() and isc_app_unblock(), which allow an application to handle signals while blocking. 416. [bug] Slave zones with no master file tried to use a NULL pointer for a journal file name when they received an IXFR. [RT #273] 415. [bug] The logging code leaked file descriptors. 414. [bug] Server did not shut down until all incoming zone transfers were finished. 413. [bug] Notify could attempt to use the zone database after it had been unloaded. [RT#267] 412. [bug] named -v didn't print the version. 411. [bug] A typo in the HS A code caused an assertion failure. 410. [bug] lwres_gethostbyname() and company set lwres_h_errno to a random value on success. 409. [bug] If named was shut down early in the startup process, ns_omapi_shutdown() would attempt to lock an uninitialized mutex. [RT #262] 408. [bug] stub zones could leak memory and reference counts if all the masters were unreachable. 407. [bug] isc_rwlock_lock() would needlessly block readers when it reached the read quota even if no writers were waiting. 406. [bug] Log messages were occasionally lost or corrupted due to a race condition in isc_log_doit(). 405. [func] Add support for selective forwarding (forward zones) 404. [bug] The request library didn't completely work with IPv6. 403. [bug] "host" did not use the search list. 402. [bug] Treat undefined acls as errors, rather than warning and then later throwing an assertion. [RT #252] 401. [func] Added simple database API. 400. [bug] SIG(0) signing and verifying was done incorrectly. [RT #249] 399. [bug] When reloading the server with a config file containing a syntax error, it could catch an assertion failure trying to perform zone maintenance on, or sending notifies from, tentatively created zones whose views were never fully configured and lacked an address database and request manager. 398. [bug] "dig" sometimes caught an assertion failure when using TSIG, depending on the key length. 397. [func] Added utility functions dns_view_gettsig() and dns_view_getpeertsig(). 396. [doc] There is now a man page for "nsupdate" in doc/man/bin/nsupdate.8. 395. [bug] nslookup printed incorrect RR type mnemonics for RRs of type >= 21 [RT #237]. 394. [bug] Current name was not propagated via $INCLUDE. 393. [func] Initial answer while loading (awl) support. Entry points: dns_master_loadfileinc(), dns_master_loadstreaminc(), dns_master_loadbufferinc(). Note: calls to dns_master_load*inc() should be rate be rate limited so as to not use up all file descriptors. 392. [func] Add ISC_R_FAMILYNOSUPPORT. Returned when OS does not support the given address family requested. 391. [clarity] ISC_R_FAMILY -> ISC_R_FAMILYMISMATCH. 390. [func] The function dns_zone_setdbtype() now takes an argc/argv style vector of words and sets both the zone database type and its arguments, making the functions dns_zone_adddbarg() and dns_zone_cleardbargs() unnecessary. 389. [bug] Attempting to send a request over IPv6 using dns_request_create() on a system without IPv6 support caused an assertion failure [RT #235]. 388. [func] dig and host can now do reverse ipv6 lookups. 387. [func] Add dns_byaddr_createptrname(), which converts an address into the name used by a PTR query. 386. [bug] Missing strdup() of ACL name caused random ACL matching failures [RT #228]. 385. [cleanup] Removed functions dns_zone_equal(), dns_zone_print(), and dns_zt_print(). 384. [bug] nsupdate was incorrectly limiting TTLs to 65535 instead of 2147483647. 383. [func] When writing a master file, print the SOA and NS records (and their SIGs) before other records. 382. [bug] named -u failed on many Linux systems where the libc provided kernel headers do not match the current kernel. 381. [bug] Check for IPV6_RECVPKTINFO and use it instead of IPV6_PKTINFO if found. [RT #229] 380. [bug] nsupdate didn't work with IPv6. 379. [func] New library function isc_sockaddr_anyofpf(). 378. [func] named and lwresd will log the command line arguments they were started with in the "starting ..." message. 377. [bug] When additional data lookups were refused due to "allow-query", the databases were still being attached causing reference leaks. 376. [bug] The server should always use good entropy when performing cryptographic functions needing entropy. 375. [bug] Per-zone "allow-query" did not properly override the view/global one for CNAME targets and additional data [RT #220]. 374. [bug] SOA in authoritative negative responses had wrong TTL. 373. [func] nslookup is now installed by "make install". 372. [bug] Deal with Microsoft DNS servers appending two bytes of garbage to zone transfer requests. 371. [bug] At high debug levels, doing an outgoing zone transfer of a very large RRset could cause an assertion failure during logging. 370. [bug] The error messages for roll-forward failures were overly terse. 369. [func] Support new named.conf options, view and zone statements: max-retry-time, min-retry-time, max-refresh-time, min-refresh-time. 368. [func] Restructure the internal ".bind" view so that more zones can be added to it. 367. [bug] Allow proper selection of server on nslookup command line. 366. [func] Allow use of '-' batch file in dig for stdin. 365. [bug] nsupdate -k leaked memory. 364. [func] Added additional-from-{cache,auth} 363. [placeholder] 362. [bug] rndc no longer aborts if the configuration file is missing an options statement. [RT #209] 361. [func] When the RBT find or chain functions set the name and origin for a node that stores the root label the name is now set to an empty name, instead of ".", to simplify later use of the name and origin by dns_name_concatenate(), dns_name_totext() or dns_name_format(). 360. [func] dns_name_totext() and dns_name_format() now allow an empty name to be passed, which is formatted as "@". 359. [bug] dnssec-signzone occasionally signed glue records. 358. [cleanup] Rename the intermediate files used by the dnssec programs. 357. [bug] The zone file parser crashed if the argument to $INCLUDE was a quoted string. 356. [cleanup] isc_task_send no longer requires event->sender to be non-null. 355. [func] Added isc_dir_createunique(), similar to mkdtemp(). 354. [doc] Man pages for the dnssec tools are now included in the distribution, in doc/man/dnssec. 353. [bug] double increment in lwres/gethost.c:copytobuf(). [RT# 187] 352. [bug] Race condition in dns_client_t startup could cause an assertion failure. 351. [bug] Constructing a response with rcode SERVFAIL to a TSIG signed query could crash the server. 350. [bug] Also-notify lists specified in the global options block were not correctly reference counted, causing a memory leak. 349. [bug] Processing a query with the CD bit set now works as expected. 348. [func] New boolean named.conf options 'additional-from-auth' and 'additional-from-cache' now supported in view and global options statement. 347. [bug] Don't crash if an argument is left off options in dig. 346. [placeholder] 345. [bug] Large-scale changes/cleanups to dig: * Significantly improve structure handling * Don't pre-load entire batch files * Add name/rr counting/limiting * Fix SIGINT handling * Shorten timeouts to match v8's behavior 344. [bug] When shutting down, lwresd sometimes tried to shut down its client tasks twice, triggering an assertion. 343. [bug] Although zone maintenance SOA queries and notify requests were signed with TSIG keys when configured for the server in case, the TSIG was not verified on the response. 342. [bug] The wrong name was being passed to dns_name_dup() when generating a TSIG key using TKEY. 341. [func] Support 'key' clause in named.conf zone masters statement to allow authentication via TSIG keys: masters { 10.0.0.1 port 5353 key "foo"; 10.0.0.2 ; }; 340. [bug] The top-level COPYRIGHT file was missing from the distribution. 339. [bug] DNSSEC validation of the response to an ANY query at a name with a CNAME RR in a secure zone triggered an assertion failure. 338. [bug] lwresd logged to syslog as named, not lwresd. 337. [bug] "dig" did not recognize "nsap-ptr" as an RR type on the command line. 336. [bug] "dig -f" used 64 k of memory for each line in the file. It now uses much less, though still proportionally to the file size. 335. [bug] named would occasionally attempt recursion when it was disallowed or undesired. 334. [func] Added hmac-md5 to libisc. 333. [bug] The resolver incorrectly accepted referrals to domains that were not parents of the query name, causing assertion failures. 332. [func] New function dns_name_reset(). 331. [bug] Only log "recursion denied" if RD is set. [RT #178] 330. [bug] Many debugging messages were partially formatted even when debugging was turned off, causing a significant decrease in query performance. 329. [func] omapi_auth_register() now takes a size_t argument for the length of a key's secret data. Previously OMAPI only stored secrets up to the first NUL byte. 328. [func] Added isc_base64_decodestring(). 327. [bug] rndc.conf parser wasn't correctly recognizing an IP address where a host specification was required. 326. [func] 'keys' in an 'inet' control statement is now required and must have at least one item in it. A "not supported" warning is now issued if a 'unix' control channel is defined. 325. [bug] isc_lex_gettoken was processing octal strings when ISC_LEXOPT_CNUMBER was not set. 324. [func] In the resolver, turn EDNS0 off if there is no response after a number of retransmissions. This is to allow queries some chance of succeeding even if all the authoritative servers of a zone silently discard EDNS0 requests instead of sending an error response like they ought to. 323. [bug] dns_rbt_findname() did not ignore empty rbt nodes. Because of this, servers authoritative for a parent and grandchild zone but not authoritative for the intervening child zone did not correctly issue referrals to the servers of the child zone. 322. [bug] Queries for KEY RRs are now sent to the parent server before the authoritative one, making DNSSEC insecurity proofs work in many cases where they previously didn't. 321. [bug] When synthesizing a CNAME RR for a DNAME response, query_addcname() failed to initialize the type and class of the CNAME dns_rdata_t, causing random failures. 320. [func] Multiple rndc changes: parses an rndc.conf file, uses authentication to talk to named, command line syntax changed. This will all be described in the ARM. 319. [func] The named.conf "controls" statement is now used to configure the OMAPI command channel. 318. [func] dns_c_ndcctx_destroy() could never return anything except ISC_R_SUCCESS; made it have void return instead. 317. [func] Use callbacks from libomapi to determine if a new connection is valid, and if a key requested to be used with that connection is valid. 316. [bug] Generate a warning if we detect an unexpected but treat as . 315. [bug] Handle non-empty blanks lines. [RT #163] 314. [func] The named.conf controls statement can now have more than one key specified for the inet clause. 313. [bug] When parsing resolv.conf, don't terminate on an error. Instead, parse as much as possible, but still return an error if one was found. 312. [bug] Increase the number of allowed elements in the resolv.conf search path from 6 to 8. If there are more than this, ignore the remainder rather than returning a failure in lwres_conf_parse. 311. [bug] lwres_conf_parse failed when the first line of resolv.conf was empty or a comment. 310. [func] Changes to named.conf "controls" statement (inet subtype only) - support "keys" clause controls { inet * port 1024 allow { any; } keys { "foo"; } } - allow "port xxx" to be left out of statement, in which case it defaults to omapi's default port of 953. 309. [bug] When sending a referral, the server did not look for name server addresses as glue in the zone holding the NS RRset in the case where this zone was not the same as the one where it looked for name server addresses as authoritative data. 308. [bug] Treat a SOA record not at top of zone as an error when loading a zone. [RT #154] 307. [bug] When canceling a query, the resolver didn't check for isc_socket_sendto() calls that did not yet have their completion events posted, so it could (rarely) end up destroying the query context and then want to use it again when the send event posted, triggering an assertion as it tried to cancel an already-canceled query. [RT #77] 306. [bug] Reading HMAC-MD5 private key files didn't work. 305. [bug] When reloading the server with a config file containing a syntax error, it could catch an assertion failure trying to perform zone maintenance on tentatively created zones whose views were never fully configured and lacked an address database. 304. [bug] If more than LWRES_CONFMAXNAMESERVERS servers are listed in resolv.conf, silently ignore them instead of returning failure. 303. [bug] Add additional sanity checks to differentiate a AXFR response vs a IXFR response. [RT #157] 302. [bug] In dig, host, and nslookup, MXNAME should be large enough to hold any legal domain name in presentation format + terminating NULL. 301. [bug] Uninitialized pointer in host:printmessage(). [RT #159] 300. [bug] Using both and didn't work on platforms lacking IPv6 because each included their own ipv6 header file for the missing definitions. Now each library's ipv6.h defines the wrapper symbol of the other (ISC_IPV6_H and LWRES_IPV6_H). 299. [cleanup] Get the user and group information before changing the root directory, so the administrator does not need to keep a copy of the user and group databases in the chroot'ed environment. Suggested by Hakan Olsson. 298. [bug] A mutex deadlock occurred during shutdown of the interface manager under certain conditions. Digital Unix systems were the most affected. 297. [bug] Specifying a key name that wasn't fully qualified in certain parts of the config file could cause an assertion failure. 296. [bug] "make install" from a separate build directory failed unless configure had been run in the source directory, too. 295. [bug] When invoked with type==CNAME and a message not constructed by dns_message_parse(), dns_message_findname() failed to find anything due to checking for attribute bits that are set only in dns_message_parse(). This caused an infinite loop when constructing the response to an ANY query at a CNAME in a secure zone. 294. [bug] If we run out of space in while processing glue when reading a master file and commit "current name" reverts to "name_current" instead of staying as "name_glue". 293. [port] Add support for FreeBSD 4.0 system tests. 292. [bug] Due to problems with the way some operating systems handle simultaneous listening on IPv4 and IPv6 addresses, the server no longer listens on IPv6 addresses by default. To revert to the previous behavior, specify "listen-on-v6 { any; };" in the config file. 291. [func] Caching servers no longer send outgoing queries over TCP just because the incoming recursive query was a TCP one. 290. [cleanup] +twiddle option to dig (for testing only) removed. 289. [cleanup] dig is now installed in $bindir instead of $sbindir. host is now installed in $bindir. (Be sure to remove any $sbindir/dig from a previous release.) 288. [func] rndc is now installed by "make install" into $sbindir. 287. [bug] rndc now works again as "rndc 127.1 reload" (for only that task). Parsing its configuration file and using digital signatures for authentication has been disabled until named supports the "controls" statement, post-9.0.0. 286. [bug] On Solaris 2, when named inherited a signal state where SIGHUP had the SIG_IGN action, SIGHUP would be ignored rather than causing the server to reload its configuration. 285. [bug] A change made to the dst API for beta4 inadvertently broke OMAPI's creation of a dst key from an incoming message, causing an assertion to be triggered. Fixed. 284. [func] The DNSSEC key generation and signing tools now generate randomness from keyboard input on systems that lack /dev/random. 283. [cleanup] The 'lwresd' program is now a link to 'named'. 282. [bug] The lexer now returns ISC_R_RANGE if parsed integer is too big for an unsigned long. 281. [bug] Fixed list of recognized config file category names. 280. [func] Add isc-config.sh, which can be used to more easily build applications that link with our libraries. 279. [bug] Private omapi function symbols shared between two or more files in libomapi.a were not namespace protected using the ISC convention of starting with the library name and two underscores ("omapi__"...) 278. [bug] bin/named/logconf.c:category_fromconf() didn't take note of when isc_log_categorybyname() wasn't able to find the category name and would then apply the channel list of the unknown category to all categories. 277. [bug] isc_log_categorybyname() and isc_log_modulebyname() would fail to find the first member of any category or module array apart from the internal defaults. Thus, for example, the "notify" category was improperly configured by named. 276. [bug] dig now supports maximum sized TCP messages. 275. [bug] The definition of lwres_gai_strerror() was missing the lwres_ prefix. 274. [bug] TSIG AXFR verify failed when talking to a BIND 8 server. 273. [func] The default for the 'transfer-format' option is now 'many-answers'. This will break zone transfers to BIND 4.9.5 and older unless there is an explicit 'one-answer' configuration. 272. [bug] The sending of large TCP responses was canceled in mid-transmission due to a race condition caused by the failure to set the client object's "newstate" variable correctly when transitioning to the "working" state. 271. [func] Attempt to probe the number of cpus in named if unspecified rather than defaulting to 1. 270. [func] Allow maximum sized TCP answers. 269. [bug] Failed DNSSEC validations could cause an assertion failure by causing clone_results() to be called with with hevent->node == NULL. 268. [doc] A plain text version of the Administrator Reference Manual is now included in the distribution, as doc/arm/Bv9ARM.txt. 267. [func] Nsupdate is now provided in the distribution. 266. [bug] zone.c:save_nsrrset() node was not initialized. 265. [bug] dns_request_create() now works for TCP. 264. [func] Dispatch can not take TCP sockets in connecting state. Set DNS_DISPATCHATTR_CONNECTED when calling dns_dispatch_createtcp() for connected TCP sockets or call dns_dispatch_starttcp() when the socket is connected. 263. [func] New logging channel type 'stderr' channel some-name { stderr; severity error; } 262. [bug] 'master' was not initialized in zone.c:stub_callback(). 261. [func] Add dns_zone_markdirty(). 260. [bug] Running named as a non-root user failed on Linux kernels new enough to support retaining capabilities after setuid(). 259. [func] New random-device and random-seed-file statements for global options block of named.conf. Both accept a single string argument. 258. [bug] Fixed printing of lwres_addr_t.address field. 257. [bug] The server detached the last zone manager reference too early, while it could still be in use by queries. This manifested itself as assertion failures during the shutdown process for busy name servers. [RT #133] 256. [func] isc_ratelimiter_t now has attach/detach semantics, and isc_ratelimiter_shutdown guarantees that the rate limiter is detached from its task. 255. [func] New function dns_zonemgr_attach(). 254. [bug] Suppress "query denied" messages on additional data lookups. --- 9.0.0b4 released --- 253. [func] resolv.conf parser now recognizes ';' and '#' as comments (anywhere in line, not just as the beginning). 252. [bug] resolv.conf parser mishandled masks on sortlists. It also aborted when an unrecognized keyword was seen, now it silently ignores the entire line. 251. [bug] lwresd caught an assertion failure on startup. 250. [bug] fixed handling of size+unit when value would be too large for internal representation. 249. [cleanup] max-cache-size config option now takes a size-spec like 'datasize', except 'default' is not allowed. 248. [bug] global lame-ttl option was not being printed when config structures were written out. 247. [cleanup] Rename cache-size config option to max-cache-size. 246. [func] Rename global option cachesize to cache-size and add corresponding option to view statement. 245. [bug] If an uncompressed name will take more than 255 bytes and the buffer is sufficiently long, dns_name_fromwire should return DNS_R_FORMERR, not ISC_R_NOSPACE. This bug caused cause the server to catch an assertion failure when it received a query for a name longer than 255 bytes. 244. [bug] empty named.conf file and empty options statement are now parsed properly. 243. [func] new cachesize option for named.conf 242. [cleanup] fixed incorrect warning about auth-nxdomain usage. 241. [cleanup] nscount and soacount have been removed from the dns_master_*() argument lists. 240. [func] databases now come in three flavours: zone, cache and stub. 239. [func] If ISC_MEM_DEBUG is enabled, the variable isc_mem_debugging controls whether messages are printed or not. 238. [cleanup] A few more compilation warnings have been quieted: + missing sigwait prototype on BSD/OS 4.0/4.0.1. + PTHREAD_ONCE_INIT unbraced initializer warnings on Solaris 2.8. + IN6ADDR_ANY_INIT unbraced initializer warnings on BSD/OS 4.*, Linux and Solaris 2.8. 237. [bug] If connect() returned ENOBUFS when the resolver was initiating a TCP query, the socket didn't get destroyed, and the server did not shut down cleanly. 236. [func] Added new listen-on-v6 config file statement. 235. [func] Consider it a config file error if a listen-on statement has an IPv6 address in it, or a listen-on-v6 statement has an IPv4 address in it. 234. [bug] Allow a trusted-key's first field (domain-name) be either a quoted or an unquoted string, instead of requiring a quoted string. 233. [cleanup] Convert all config structure integer values to unsigned integer (isc_uint32_t) to match grammar. 232. [bug] Allow slave zones to not have a file. 231. [func] Support new 'port' clause in config file options section. Causes 'listen-on', 'masters' and 'also-notify' statements to use its value instead of default (53). 230. [func] Replace the dst sign/verify API with a cleaner one. 229. [func] Support config file sig-validity-interval statement in options, views and zone statements (master zones only). 228. [cleanup] Logging messages in config module stripped of trailing period. 227. [cleanup] The enumerated identifiers dns_rdataclass_*, dns_rcode_*, dns_opcode_*, and dns_trust_* are also now cast to their appropriate types, as with dns_rdatatype_* in item number 225 below. 226. [func] dns_name_totext() now always prints the root name as '.', even when omit_final_dot is true. 225. [cleanup] The enumerated dns_rdatatype_* identifiers are now cast to dns_rdatatype_t via macros of their same name so that they are of the proper integral type wherever a dns_rdatatype_t is needed. 224. [cleanup] The entire project builds cleanly with gcc's -Wcast-qual and -Wwrite-strings warnings enabled, which is now the default when using gcc. (Warnings from confparser.c, because of yacc's code, are unfortunately to be expected.) 223. [func] Several functions were re-prototyped to qualify one or more of their arguments with "const". Similarly, several functions that return pointers now have those pointers qualified with const. 222. [bug] The global 'also-notify' option was ignored. 221. [bug] An uninitialized variable was sometimes passed to dns_rdata_freestruct() when loading a zone, causing an assertion failure. 220. [cleanup] Set the default outgoing port in the view, and set it in sockaddrs returned from the ADB. [31-May-2000 explorer] 219. [bug] Signed truncated messages more correctly follow the respective specs. 218. [func] When an rdataset is signed, its ttl is normalized based on the signature validity period. 217. [func] Also-notify and trusted-keys can now be used in the 'view' statement. 216. [func] The 'max-cache-ttl' and 'max-ncache-ttl' options now work. 215. [bug] Failures at certain points in request processing could cause the assertion INSIST(client->lockview == NULL) to be triggered. 214. [func] New public function isc_netaddr_format(), for formatting network addresses in log messages. 213. [bug] Don't leak memory when reloading the zone if an update-policy clause was present in the old zone. 212. [func] Added dns_message_get/settsigkey, to make TSIG key management reasonable. 211. [func] The 'key' and 'server' statements can now occur inside 'view' statements. 210. [bug] The 'allow-transfer' option was ignored for slave zones, and the 'transfers-per-ns' option was was ignored for all zones. 209. [cleanup] Upgraded openssl files to new version 0.9.5a 208. [func] Added ISC_OFFSET_MAXIMUM for the maximum value of an isc_offset_t. 207. [func] The dnssec tools properly use the logging subsystem. 206. [cleanup] dst now stores the key name as a dns_name_t, not a char *. 205. [cleanup] On IRIX, turn off the mostly harmless warnings 1692 ("prototyped function redeclared without prototype") and 1552 ("variable ... set but not used") when compiling in the lib/dns/sec/{dnssafe,openssl} directories, which contain code imported from outside sources. 204. [cleanup] On HP/UX, pass +vnocompatwarnings to the linker to quiet the warnings that "The linked output may not run on a PA 1.x system." 203. [func] notify and zone soa queries are now tsig signed when appropriate. 202. [func] isc_lex_getsourceline() changed from returning int to returning unsigned long, the type of its underlying counter. 201. [cleanup] Removed the test/sdig program, it has been replaced by bin/dig/dig. --- 9.0.0b3 released --- 200. [bug] Failures in sending query responses to clients (e.g., running out of network buffers) were not logged. 199. [bug] isc_heap_delete() sometimes violated the heap invariant, causing timer events not to be posted when due. 198. [func] Dispatch managers hold memory pools which any managed dispatcher may use. This allows us to avoid dipping into the memory context for most allocations. [19-May-2000 explorer] 197. [bug] When an incoming AXFR or IXFR completes, the zone's internal state is refreshed from the SOA data. [19-May-2000 explorer] 196. [func] Dispatchers can be shared easily between views and/or interfaces. [19-May-2000 explorer] 195. [bug] Including the NXT record of the root domain in a negative response caused an assertion failure. 194. [doc] The PDF version of the Administrator's Reference Manual is no longer included in the ISC BIND9 distribution. 193. [func] changed dst_key_free() prototype. 192. [bug] Zone configuration validation is now done at end of config file parsing, and before loading callbacks. 191. [func] Patched to compile on UnixWare 7.x. This platform is not directly supported by the ISC. 190. [cleanup] The DNSSEC tools have been moved to a separate directory dnssec/ and given the following new, more descriptive names: dnssec-keygen dnssec-signzone dnssec-signkey dnssec-makekeyset Their command line arguments have also been changed to be more consistent. dnssec-keygen now prints the name of the generated key files (sans extension) on standard output to simplify its use in automated scripts. 189. [func] isc_time_secondsastimet(), a new function, will ensure that the number of seconds in an isc_time_t does not exceed the range of a time_t, or return ISC_R_RANGE. Similarly, isc_time_now(), isc_time_nowplusinterval(), isc_time_add() and isc_time_subtract() now check the range for overflow/underflow. In the case of isc_time_subtract, this changed a calling requirement (ie, something that could generate an assertion) into merely a condition that returns an error result. isc_time_add() and isc_time_subtract() were void- valued before but now return isc_result_t. 188. [func] Log a warning message when an incoming zone transfer contains out-of-zone data. 187. [func] isc_ratelimiter_enqueue() has an additional argument 'task'. 186. [func] dns_request_getresponse() has an additional argument 'preserve_order'. 185. [bug] Fixed up handling of ISC_MEMCLUSTER_LEGACY. Several public functions did not have an isc__ prefix, and referred to functions that had previously been renamed. 184. [cleanup] Variables/functions which began with two leading underscores were made to conform to the ANSI/ISO standard, which says that such names are reserved. 183. [func] ISC_LOG_PRINTTAG option for log channels. Useful for logging the program name or other identifier. 182. [cleanup] New command-line parameters for dnssec tools 181. [func] Added dst_key_buildfilename and dst_key_parsefilename 180. [func] New isc_result_t ISC_R_RANGE. Supersedes DNS_R_RANGE. 179. [func] options named.conf statement *must* now come before any zone or view statements. 178. [func] Post-load of named.conf check verifies a slave zone has non-empty list of masters defined. 177. [func] New per-zone boolean: enable-zone yes | no ; intended to let a zone be disabled without having to comment out the entire zone statement. 176. [func] New global and per-view option: max-cache-ttl number 175. [func] New global and per-view option: additional-data internal | minimal | maximal; 174. [func] New public function isc_sockaddr_format(), for formatting socket addresses in log messages. 173. [func] Keep a queue of zones waiting for zone transfer quota so that a new transfer can be dispatched immediately whenever quota becomes available. 172. [bug] $TTL directive was sometimes missing from dumped master files because totext_ctx_init() failed to initialize ctx->current_ttl_valid. 171. [cleanup] On NetBSD systems, the mit-pthreads or unproven-pthreads library is now always used unless --with-ptl2 is explicitly specified on the configure command line. The --with-mit-pthreads option is no longer needed and has been removed. 170. [cleanup] Remove inter server consistency checks from zone, these should return as a separate module in 9.1. dns_zone_checkservers(), dns_zone_checkparents(), dns_zone_checkchildren(), dns_zone_checkglue(). Remove dns_zone_setadb(), dns_zone_setresolver(), dns_zone_setrequestmgr() these should now be found via the view. 169. [func] ratelimiter can now process N events per interval. 168. [bug] include statements in named.conf caused syntax errors due to not consuming the semicolon ending the include statement before switching input streams. 167. [bug] Make lack of masters for a slave zone a soft error. 166. [bug] Keygen was overwriting existing keys if key_id conflicted, now it will retry, and non-null keys with key_id == 0 are not generated anymore. Key was not able to generate NOAUTHCONF DSA key, increased RSA key size to 2048 bits. 165. [cleanup] Silence "end-of-loop condition not reached" warnings from Solaris compiler. 164. [func] Added functions isc_stdio_open(), isc_stdio_close(), isc_stdio_seek(), isc_stdio_read(), isc_stdio_write(), isc_stdio_flush(), isc_stdio_sync(), isc_file_remove() to encapsulate nonportable usage of errno and sync. 163. [func] Added result codes ISC_R_FILENOTFOUND and ISC_R_FILEEXISTS. 162. [bug] Ensure proper range for arguments to ctype.h functions. 161. [cleanup] error in yyparse prototype that only HPUX caught. 160. [cleanup] getnet*() are not going to be implemented at this stage. 159. [func] Redefinition of config file elements is now an error (instead of a warning). 158. [bug] Log channel and category list copy routines weren't assigning properly to output parameter. 157. [port] Fix missing prototype for getopt(). 156. [func] Support new 'database' statement in zone. database "quoted-string"; 155. [bug] ns_notify_start() was not detaching the found zone. 154. [func] The signer now logs libdns warnings to stderr even when not verbose, and in a nicer format. 153. [func] dns_rdata_tostruct() 'mctx' is now optional. If 'mctx' is NULL then you need to preserve the 'rdata' until you have finished using the structure as there may be references to the associated memory. If 'mctx' is non-NULL it is guaranteed that there are no references to memory associated with 'rdata'. dns_rdata_freestruct() must be called if 'mctx' was non-NULL and may safely be called if 'mctx' was NULL. 152. [bug] keygen dumped core if domain name argument was omitted from command line. 151. [func] Support 'disabled' statement in zone config (causes zone to be parsed and then ignored). Currently must come after the 'type' clause. 150. [func] Support optional ports in masters and also-notify statements: masters [ port xxx ] { y.y.y.y [ port zzz ] ; } 149. [cleanup] Removed unused argument 'olist' from dns_c_view_unsetordering(). 148. [cleanup] Stop issuing some warnings about some configuration file statements that were not implemented, but now are. 147. [bug] Changed yacc union size to be smaller for yaccs that put yacc-stack on the real stack. 146. [cleanup] More general redundant header file cleanup. Rather than continuing to itemize every header which changed, this changelog entry just notes that if a header file did not need another header file that it was including in order to provide its advertised functionality, the inclusion of the other header file was removed. See util/check-includes for how this was tested. 145. [cleanup] Added and ISC_LANG_BEGINDECLS/ ISC_LANG_ENDDECLS to header files that had function prototypes, and removed it from those that did not. 144. [cleanup] libdns header files too numerous to name were made to conform to the same style for multiple inclusion protection. 143. [func] Added function dns_rdatatype_isknown(). 142. [cleanup] does not need or . 141. [bug] Corrupt requests with multiple questions could cause an assertion failure. 140. [cleanup] does not need or . 139. [cleanup] now includes instead of and . 138. [cleanup] isc_strtouq moved from str.[ch] to string.[ch] and renamed isc_string_touint64. isc_strsep moved from strsep.c to string.c and renamed isc_string_separate. 137. [cleanup] , , , and made to conform to the same style for multiple inclusion protection. 136. [cleanup] , , and Win32's needed ISC_LANG_BEGINDECLS/ISC_LANG_ENDDECLS. 135. [cleanup] Win32's did not need or , now uses in place of , and needed ISC_LANG_BEGINDECLS and ISC_LANG_ENDDECLS. 134. [cleanup] does not need . 133. [cleanup] needs . 132. [cleanup] does not need , but does need . 131. [cleanup] and need for ISC_R_* codes used in macros. 130. [cleanup] does not need or , and now includes instead of . 129. [bug] The 'default_debug' log channel was not set up when 'category default' was present in the config file 128. [cleanup] had ISC_LANG_BEGINDECLS instead of ISC_LANG_ENDDECLS at end of header. 127. [cleanup] The contracts for the comparison routines dns_name_fullcompare(), dns_name_compare(), dns_name_rdatacompare(), and dns_rdata_compare() now specify that the order value returned is < 0, 0, or > 0 instead of -1, 0, or 1. 126. [cleanup] and need . 125. [cleanup] , , , , , , and do not need . 124. [func] signer now imports parent's zone key signature and creates null keys/sets zone status bit for children when necessary 123. [cleanup] does not need . 122. [cleanup] does not need or . 121. [cleanup] does not need or . Multiple inclusion protection symbol fixed from ISC_SYMBOL_H to ISC_SYMTAB_H. isc_symtab_t moved to . 120. [cleanup] does not need , , , or . 119. [cleanup] structure definitions for generic rdata structures do not have _generic_ in their names. 118. [cleanup] libdns.a is now namespace-clean, on NetBSD, excepting YACC crust (yyparse, etc) [2000-apr-27 explorer] 117. [cleanup] libdns.a changes: dns_zone_clearnotify() and dns_zone_addnotify() are replaced by dns_zone_setnotifyalso(). dns_zone_clearmasters() and dns_zone_addmaster() are replaced by dns_zone_setmasters(). 116. [func] Added for isc_offset_t (aka off_t on Unix systems). 115. [port] Shut up the -Wmissing-declarations warning about 's __sputaux on BSD/OS pre-4.1. 114. [cleanup] does not need or . 113. [func] Utility programs dig and host added. 112. [cleanup] does not need . 111. [cleanup] does not need or . 110. [cleanup] does not need or . 109. [bug] "make depend" did nothing for bin/tests/{db,mem,sockaddr,tasks,timers}/. 108. [cleanup] DNS_SETBIT/DNS_GETBIT/DNS_CLEARBIT moved from to and renamed to DNS_BIT_SET/DNS_BIT_GET/DNS_BIT_CLEAR. 107. [func] Add keysigner and keysettool. 106. [func] Allow dnssec verifications to ignore the validity period. Used by several of the dnssec tools. 105. [doc] doc/dev/coding.html expanded with other implicit conventions the developers have used. 104. [bug] Made compress_add and compress_find static to lib/dns/compress.c. 103. [func] libisc buffer API changes for : Added: isc_buffer_base(b) (pointer) isc_buffer_current(b) (pointer) isc_buffer_active(b) (pointer) isc_buffer_used(b) (pointer) isc_buffer_length(b) (int) isc_buffer_usedlength(b) (int) isc_buffer_consumedlength(b) (int) isc_buffer_remaininglength(b) (int) isc_buffer_activelength(b) (int) isc_buffer_availablelength(b) (int) Removed: ISC_BUFFER_USEDCOUNT(b) ISC_BUFFER_AVAILABLECOUNT(b) isc_buffer_type(b) Changed names: isc_buffer_used(b, r) -> isc_buffer_usedregion(b, r) isc_buffer_available(b, r) -> isc_buffer_available_region(b, r) isc_buffer_consumed(b, r) -> isc_buffer_consumedregion(b, r) isc_buffer_active(b, r) -> isc_buffer_activeregion(b, r) isc_buffer_remaining(b, r) -> isc_buffer_remainingregion(b, r) Buffer types were removed, so the ISC_BUFFERTYPE_* macros are no more, and the type argument to isc_buffer_init and isc_buffer_allocate were removed. isc_buffer_putstr is now void (instead of isc_result_t) and requires that the caller ensure that there is enough available buffer space for the string. 102. [port] Correctly detect inet_aton, inet_pton and inet_ptop on BSD/OS 4.1. 101. [cleanup] Quieted EGCS warnings from lib/isc/print.c. 100. [cleanup] does not need or . isc_random_t moved to . 99. [cleanup] Rate limiter now has separate shutdown() and destroy() functions, and it guarantees that all queued events are delivered even in the shutdown case. 98. [cleanup] does not need or unless ISC_PLATFORM_NEEDVSNPRINTF is defined. 97. [cleanup] does not need or . 96. [cleanup] does not need . 95. [cleanup] does not need . 94. [cleanup] Some installed header files did not compile as C++. 93. [cleanup] does not need . 92. [cleanup] does not need , , or . 91. [cleanup] does not need or . 90. [cleanup] Removed unneeded ISC_LANG_BEGINDECLS/ISC_LANG_ENDDECLS from . 89. [cleanup] does not need . 88. [cleanup] does not need or . isc_interface_t and isc_interfaceiter_t moved to . 87. [cleanup] does not need , or . 86. [cleanup] isc_bufferlist_t moved from to . 85. [cleanup] does not need , , , or . 84. [func] allow-query ACL checks now apply to all data added to a response. 83. [func] If the server is authoritative for both a delegating zone and its (nonsecure) delegatee, and a query is made for a KEY RR at the top of the delegatee, then the server will look for a KEY in the delegator if it is not found in the delegatee. 82. [cleanup] does not need . 81. [cleanup] and do not need . 80. [cleanup] does not need or . 79. [cleanup] does not need . 78. [cleanup] lwres_conftest renamed to lwresconf_test for consistency with other *_test programs. 77. [cleanup] typedef of isc_time_t and isc_interval_t moved from to . 76. [cleanup] Rewrote keygen. 75. [func] Don't load a zone if its database file is older than the last time the zone was loaded. 74. [cleanup] Removed mktemplate.o and ufile.o from libisc.a, subsumed by file.o. 73. [func] New "file" API in libisc, including new function isc_file_getmodtime, isc_mktemplate renamed to isc_file_mktemplate and isc_ufile renamed to isc_file_openunique. By no means an exhaustive API, it is just what's needed for now. 72. [func] DNS_RBTFIND_NOPREDECESSOR and DNS_RBTFIND_NOOPTIONS added for dns_rbt_findnode, the former to disable the setting of the chain to the predecessor, and the latter to make clear when no options are set. 71. [cleanup] Made explicit the implicit REQUIREs of isc_time_seconds, isc_time_nanoseconds, and isc_time_subtract. 70. [func] isc_time_set() added. 69. [bug] The zone object's master and also-notify lists grew longer with each server reload. 68. [func] Partial support for SIG(0) on incoming messages. 67. [performance] Allow use of alternate (compile-time supplied) OpenSSL libraries/headers. 66. [func] Data in authoritative zones should have a trust level beyond secure. 65. [cleanup] Removed obsolete typedef of dns_zone_callbackarg_t from . 64. [func] The RBT, DB, and zone table APIs now allow the caller find the most-enclosing superdomain of a name. 63. [func] Generate NOTIFY messages. 62. [func] Add UDP refresh support. 61. [cleanup] Use single quotes consistently in log messages. 60. [func] Catch and disallow singleton types on message parse. 59. [bug] Cause net/host unreachable to be a hard error when sending and receiving. 58. [bug] bin/named/query.c could sometimes trigger the (client->query.attributes & NS_QUERYATTR_NAMEBUFUSED) == 0 assertion in query_newname(). 57. [func] Added dns_nxt_typepresent() 56. [bug] SIG records were not properly returned in cached negative answers. 55. [bug] Responses containing multiple names in the authority section were not negatively cached. 54. [bug] If a fetch with sigrdataset==NULL joined one with sigrdataset!=NULL or vice versa, the resolver could catch an assertion or lose signature data, respectively. 53. [port] freebsd 4.0: lib/isc/unix/socket.c requires . 52. [bug] rndc: taskmgr and socketmgr were not initialized to NULL. 51. [cleanup] dns/compress.h and dns/zt.h did not need to include dns/rbt.h; it was needed only by compress.c and zt.c. 50. [func] RBT deletion no longer requires a valid chain to work, and dns_rbt_deletenode was added. 49. [func] Each cache now has its own mctx. 48. [func] isc_task_create() no longer takes an mctx. isc_task_mem() has been eliminated. 47. [func] A number of modules now use memory context reference counting. 46. [func] Memory contexts are now reference counted. Added isc_mem_inuse() and isc_mem_preallocate(). Renamed isc_mem_destroy_check() to isc_mem_setdestroycheck(). 45. [bug] The trusted-key statement incorrectly loaded keys. 44. [bug] Don't include authority data if it would force us to unset the AD bit in the message. 43. [bug] DNSSEC verification of cached rdatasets was failing. 42. [cleanup] Simplified logging of messages with embedded domain names by introducing a new convenience function dns_name_format(). 41. [func] Use PR_SET_KEEPCAPS on Linux 2.3.99-pre3 and later to allow 'named' to run as a non-root user while retaining the ability to bind() to privileged ports. 40. [func] Introduced new logging category "dnssec" and logging module "dns/validator". 39. [cleanup] Moved the typedefs for isc_region_t, isc_textregion_t, and isc_lex_t to . 38. [bug] TSIG signed incoming zone transfers work now. 37. [bug] If the first RR in an incoming zone transfer was not an SOA, the server died with an assertion failure instead of just reporting an error. 36. [cleanup] Change DNS_R_SUCCESS (and others) to ISC_R_SUCCESS 35. [performance] Log messages which are of a level too high to be logged by any channel in the logging configuration will not cause the log mutex to be locked. 34. [bug] Recursion was allowed even with 'recursion no'. 33. [func] The RBT now maintains a parent pointer at each node. 32. [cleanup] bin/lwresd/client.c needs for memset() prototype. 31. [bug] Use ${LIBTOOL} to compile bin/named/main.@O@. 30. [func] config file grammar change to support optional class type for a view. 29. [func] support new config file view options: auth-nxdomain recursion query-source query-source-v6 transfer-source transfer-source-v6 max-transfer-time-out max-transfer-idle-out transfer-format request-ixfr provide-ixfr cleaning-interval fetch-glue notify rfc2308-type1 lame-ttl max-ncache-ttl min-roots 28. [func] support lame-ttl, min-roots and serial-queries config global options. 27. [bug] Only include on BSD/OS 4.[01]*. Including it on other platforms (eg, NetBSD) can cause a forced #error from the C preprocessor. 26. [func] new match-clients statement in config file view. 25. [bug] make install failed to install and . 24. [cleanup] Eliminate some unnecessary #includes of header files from header files. 23. [cleanup] Provide more context in log messages about client requests, using a new function ns_client_log(). 22. [bug] SIGs weren't returned in the answer section when the query resulted in a fetch. 21. [port] Look at STD_CINCLUDES after CINCLUDES during compilation, so additional system include directories can be searched but header files in the bind9 source tree with conflicting names take precedence. This avoids issues with installed versions of dnssafe and openssl. 20. [func] Configuration file post-load validation of zones failed if there were no zones. 19. [bug] dns_zone_notifyreceive() failed to unlock the zone lock in certain error cases. 18. [bug] Use AC_TRY_LINK rather than AC_TRY_COMPILE in configure.in to check for presence of in6addr_any. 17. [func] Do configuration file post-load validation of zones. 16. [bug] put quotes around key names on config file output to avoid possible keyword clashes. 15. [func] Add dns_name_dupwithoffsets(). This function is improves comparison performance for duped names. 14. [bug] free_rbtdb() could have 'put' unallocated memory in an unlikely error path. 13. [bug] lib/dns/master.c and lib/dns/xfrin.c didn't ignore out-of-zone data. 12. [bug] Fixed possible uninitialized variable error. 11. [bug] axfr_rrstream_first() didn't check the result code of db_rr_iterator_first(), possibly causing an assertion to be triggered later. 10. [bug] A bug in the code which makes EDNS0 OPT records in bin/named/client.c and lib/dns/resolver.c could trigger an assertion. 9. [cleanup] replaced bit-setting code in confctx.c and replaced repeated code with macro calls. 8. [bug] Shutdown of incoming zone transfer accessed freed memory. 7. [cleanup] removed 'listen-on' from view statement. 6. [bug] quote RR names when generating config file to prevent possible clash with config file keywords (such as 'key'). 5. [func] syntax change to named.conf file: new ssu grant/deny statements must now be enclosed by an 'update-policy' block. 4. [port] bin/named/unix/os.c didn't compile on systems with linux 2.3 kernel includes due to conflicts between C library includes and the kernel includes. We now get only what we need from , and avoid pulling in other linux kernel .h files. 3. [bug] TKEYs go in the answer section of responses, not the additional section. 2. [bug] Generating cryptographic randomness failed on systems without /dev/random. 1. [bug] The installdirs rule in lib/isc/unix/include/isc/Makefile.in had a typo which prevented the isc directory from being created if it didn't exist. --- 9.0.0b2 released --- # This tells Emacs to use hard tabs in this file. # Local Variables: # indent-tabs-mode: t # End: bind-9.6-ESV-R6/COPYRIGHT000644 024064 023255 00000062563 11734112744 014633 0ustar00eachsweng000000 000000 Copyright (C) 2004-2012 Internet Systems Consortium, Inc.

("ISC") Copyright © 2000-2003 Internet Software Consortium. ----------------------------------------------------------------------- 1. Compilation and Installation Questions Q: I'm trying to compile BIND 9, and "make" is failing due to files not being found. Why? A: Using a parallel or distributed "make" to build BIND 9 is not supported, and doesn't work. If you are using one of these, use normal make or gmake instead. Q: Isn't "make install" supposed to generate a default named.conf? A: Short Answer: No. Long Answer: There really isn't a default configuration which fits any site perfectly. There are lots of decisions that need to be made and there is no consensus on what the defaults should be. For example FreeBSD uses /etc/namedb as the location where the configuration files for named are stored. Others use /var/named. What addresses to listen on? For a laptop on the move a lot you may only want to listen on the loop back interfaces. Who do you offer recursive service to? Is there are firewall to consider? If so is it stateless or stateful. Are you directly on the Internet? Are you on a private network? Are you on a NAT'd network? The answers to all these questions change how you configure even a caching name server. 2. Configuration and Setup Questions Q: Why does named log the warning message "no TTL specified - using SOA MINTTL instead"? A: Your zone file is illegal according to RFC1035. It must either have a line like: $TTL 86400 at the beginning, or the first record in it must have a TTL field, like the "84600" in this example: example.com. 86400 IN SOA ns hostmaster ( 1 3600 1800 1814400 3600 ) Q: Why do I get errors like "dns_zone_load: zone foo/IN: loading master file bar: ran out of space"? A: This is often caused by TXT records with missing close quotes. Check that all TXT records containing quoted strings have both open and close quotes. Q: How do I restrict people from looking up the server version? A: Put a "version" option containing something other than the real version in the "options" section of named.conf. Note doing this will not prevent attacks and may impede people trying to diagnose problems with your server. Also it is possible to "fingerprint" nameservers to determine their version. Q: How do I restrict only remote users from looking up the server version? A: The following view statement will intercept lookups as the internal view that holds the version information will be matched last. The caveats of the previous answer still apply, of course. view "chaos" chaos { match-clients { ; }; allow-query { none; }; zone "." { type hint; file "/dev/null"; // or any empty file }; }; Q: What do "no source of entropy found" or "could not open entropy source foo" mean? A: The server requires a source of entropy to perform certain operations, mostly DNSSEC related. These messages indicate that you have no source of entropy. On systems with /dev/random or an equivalent, it is used by default. A source of entropy can also be defined using the random-device option in named.conf. Q: I'm trying to use TSIG to authenticate dynamic updates or zone transfers. I'm sure I have the keys set up correctly, but the server is rejecting the TSIG. Why? A: This may be a clock skew problem. Check that the the clocks on the client and server are properly synchronised (e.g., using ntp). Q: I see a log message like the following. Why? couldn't open pid file '/var/run/named.pid': Permission denied A: You are most likely running named as a non-root user, and that user does not have permission to write in /var/run. The common ways of fixing this are to create a /var/run/named directory owned by the named user and set pid-file to "/var/run/named/named.pid", or set pid-file to "named.pid", which will put the file in the directory specified by the directory option (which, in this case, must be writable by the named user). Q: I can query the nameserver from the nameserver but not from other machines. Why? A: This is usually the result of the firewall configuration stopping the queries and / or the replies. Q: How can I make a server a slave for both an internal and an external view at the same time? When I tried, both views on the slave were transferred from the same view on the master. A: You will need to give the master and slave multiple IP addresses and use those to make sure you reach the correct view on the other machine. Master: 10.0.1.1 (internal), 10.0.1.2 (external, IP alias) internal: match-clients { !10.0.1.2; !10.0.1.4; 10.0.1/24; }; notify-source 10.0.1.1; transfer-source 10.0.1.1; query-source address 10.0.1.1; external: match-clients { any; }; recursion no; // don't offer recursion to the world notify-source 10.0.1.2; transfer-source 10.0.1.2; query-source address 10.0.1.2; Slave: 10.0.1.3 (internal), 10.0.1.4 (external, IP alias) internal: match-clients { !10.0.1.2; !10.0.1.4; 10.0.1/24; }; notify-source 10.0.1.3; transfer-source 10.0.1.3; query-source address 10.0.1.3; external: match-clients { any; }; recursion no; // don't offer recursion to the world notify-source 10.0.1.4; transfer-source 10.0.1.4; query-source address 10.0.1.4; You put the external address on the alias so that all the other dns clients on these boxes see the internal view by default. A: BIND 9.3 and later: Use TSIG to select the appropriate view. Master 10.0.1.1: key "external" { algorithm hmac-sha256; secret "xxxxxxxxxxxxxxxxxxxxxxxx"; }; view "internal" { match-clients { !key external; // reject message ment for the // external view. 10.0.1/24; }; // accept from these addresses. ... }; view "external" { match-clients { key external; any; }; server 10.0.1.2 { keys external; }; // tag messages from the // external view to the // other servers for the // view. recursion no; ... }; Slave 10.0.1.2: key "external" { algorithm hmac-sha256; secret "xxxxxxxxxxxxxxxxxxxxxxxx"; }; view "internal" { match-clients { !key external; 10.0.1/24; }; ... }; view "external" { match-clients { key external; any; }; server 10.0.1.1 { keys external; }; recursion no; ... }; Q: I get error messages like "multiple RRs of singleton type" and "CNAME and other data" when transferring a zone. What does this mean? A: These indicate a malformed master zone. You can identify the exact records involved by transferring the zone using dig then running named-checkzone on it. dig axfr example.com @master-server > tmp named-checkzone example.com tmp A CNAME record cannot exist with the same name as another record except for the DNSSEC records which prove its existence (NSEC). RFC 1034, Section 3.6.2: "If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types." Q: I get error messages like "named.conf:99: unexpected end of input" where 99 is the last line of named.conf. A: There are unbalanced quotes in named.conf. A: Some text editors (notepad and wordpad) fail to put a line title indication (e.g. CR/LF) on the last line of a text file. This can be fixed by "adding" a blank line to the end of the file. Named expects to see EOF immediately after EOL and treats text files where this is not met as truncated. Q: How do I share a dynamic zone between multiple views? A: You choose one view to be master and the second a slave and transfer the zone between views. Master 10.0.1.1: key "external" { algorithm hmac-sha256; secret "xxxxxxxxxxxxxxxxxxxxxxxx"; }; key "mykey" { algorithm hmac-sha256; secret "yyyyyyyyyyyyyyyyyyyyyyyy"; }; view "internal" { match-clients { !key external; 10.0.1/24; }; server 10.0.1.1 { /* Deliver notify messages to external view. */ keys { external; }; }; zone "example.com" { type master; file "internal/example.db"; allow-update { key mykey; }; also-notify { 10.0.1.1; }; }; }; view "external" { match-clients { key external; any; }; zone "example.com" { type slave; file "external/example.db"; masters { 10.0.1.1; }; transfer-source 10.0.1.1; // allow-update-forwarding { any; }; // allow-notify { ... }; }; }; Q: I get a error message like "zone wireless.ietf56.ietf.org/IN: loading master file primaries/wireless.ietf56.ietf.org: no owner". A: This error is produced when a line in the master file contains leading white space (tab/space) but the is no current record owner name to inherit the name from. Usually this is the result of putting white space before a comment, forgetting the "@" for the SOA record, or indenting the master file. Q: Why are my logs in GMT (UTC). A: You are running chrooted (-t) and have not supplied local timezone information in the chroot area. FreeBSD: /etc/localtime Solaris: /etc/TIMEZONE and /usr/share/lib/zoneinfo OSF: /etc/zoneinfo/localtime See also tzset(3) and zic(8). Q: I get "rndc: connect failed: connection refused" when I try to run rndc. A: This is usually a configuration error. First ensure that named is running and no errors are being reported at startup (/var/log/messages or equivalent). Running "named -g " from a title can help at this point. Secondly ensure that named is configured to use rndc either by "rndc-confgen -a", rndc-confgen or manually. The Administrators Reference manual has details on how to do this. Old versions of rndc-confgen used localhost rather than 127.0.0.1 in / etc/rndc.conf for the default server. Update /etc/rndc.conf if necessary so that the default server listed in /etc/rndc.conf matches the addresses used in named.conf. "localhost" has two address (127.0.0.1 and ::1). If you use "rndc-confgen -a" and named is running with -t or -u ensure that /etc/rndc.conf has the correct ownership and that a copy is in the chroot area. You can do this by re-running "rndc-confgen -a" with appropriate -t and -u arguments. Q: I get "transfer of 'example.net/IN' from 192.168.4.12#53: failed while receiving responses: permission denied" error messages. A: These indicate a filesystem permission error preventing named creating / renaming the temporary file. These will usually also have other associated error messages like "dumping master file: sl/tmp-XXXX5il3sQ: open: permission denied" Named needs write permission on the directory containing the file. Named writes the new cache file to a temporary file then renames it to the name specified in named.conf to ensure that the contents are always complete. This is to prevent named loading a partial zone in the event of power failure or similar interrupting the write of the master file. Note file names are relative to the directory specified in options and any chroot directory ([/][]). If named is invoked as "named -t /chroot/DNS" with the following named.conf then "/chroot/DNS/var/named/sl" needs to be writable by the user named is running as. options { directory "/var/named"; }; zone "example.net" { type slave; file "sl/example.net"; masters { 192.168.4.12; }; }; Q: I want to forward all DNS queries from my caching nameserver to another server. But there are some domains which have to be served locally, via rbldnsd. How do I achieve this ? A: options { forward only; forwarders { ; }; }; zone "sbl-xbl.spamhaus.org" { type forward; forward only; forwarders { port 530; }; }; zone "list.dsbl.org" { type forward; forward only; forwarders { port 530; }; }; Q: Can you help me understand how BIND 9 uses memory to store DNS zones? Some times it seems to take several times the amount of memory it needs to store the zone. A: When reloading a zone named my have multiple copies of the zone in memory at one time. The zone it is serving and the one it is loading. If reloads are ultra fast it can have more still. e.g. Ones that are transferring out, the one that it is serving and the one that is loading. BIND 8 destroyed the zone before loading and also killed off outgoing transfers of the zone. The new strategy allows slaves to get copies of the new zone regardless of how often the master is loaded compared to the transfer time. The slave might skip some intermediate versions but the transfers will complete and it will keep reasonably in sync with the master. The new strategy also allows the master to recover from syntax and other errors in the master file as it still has an in-core copy of the old contents. Q: I want to use IPv6 locally but I don't have a external IPv6 connection. External lookups are slow. A: You can use server clauses to stop named making external lookups over IPv6. server fd81:ec6c:bd62::/48 { bogus no; }; // site ULA prefix server ::/0 { bogus yes; }; 3. Operations Questions Q: How to change the nameservers for a zone? A: Step 1: Ensure all nameservers, new and old, are serving the same zone content. Step 2: Work out the maximum TTL of the NS RRset in the parent and child zones. This is the time it will take caches to be clear of a particular version of the NS RRset. If you are just removing nameservers you can skip to Step 6. Step 3: Add new nameservers to the NS RRset for the zone and wait until all the servers for the zone are answering with this new NS RRset. Step 4: Inform the parent zone of the new NS RRset then wait for all the parent servers to be answering with the new NS RRset. Step 5: Wait for cache to be clear of the old NS RRset. See Step 2 for how long. If you are just adding nameservers you are done. Step 6: Remove any old nameservers from the zones NS RRset and wait for all the servers for the zone to be serving the new NS RRset. Step 7: Inform the parent zone of the new NS RRset then wait for all the parent servers to be answering with the new NS RRset. Step 8: Wait for cache to be clear of the old NS RRset. See Step 2 for how long. Step 9: Turn off the old nameservers or remove the zone entry from the configuration of the old nameservers. Step 10: Increment the serial number and wait for the change to be visible in all nameservers for the zone. This ensures that zone transfers are still working after the old servers are decommissioned. Note: the above procedure is designed to be transparent to dns clients. Decommissioning the old servers too early will result in some clients not being able to look up answers in the zone. Note: while it is possible to run the addition and removal stages together it is not recommended. 4. General Questions Q: I keep getting log messages like the following. Why? Dec 4 23:47:59 client 10.0.0.1#1355: updating zone 'example.com/IN': update failed: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) A: DNS updates allow the update request to test to see if certain conditions are met prior to proceeding with the update. The message above is saying that conditions were not met and the update is not proceeding. See doc/rfc/rfc2136.txt for more details on prerequisites. Q: I keep getting log messages like the following. Why? Jun 21 12:00:00.000 client 10.0.0.1#1234: update denied A: Someone is trying to update your DNS data using the RFC2136 Dynamic Update protocol. Windows 2000 machines have a habit of sending dynamic update requests to DNS servers without being specifically configured to do so. If the update requests are coming from a Windows 2000 machine, see for information about how to turn them off. Q: When I do a "dig . ns", many of the A records for the root servers are missing. Why? A: This is normal and harmless. It is a somewhat confusing side effect of the way BIND 9 does RFC2181 trust ranking and of the efforts BIND 9 makes to avoid promoting glue into answers. When BIND 9 first starts up and primes its cache, it receives the root server addresses as additional data in an authoritative response from a root server, and these records are eligible for inclusion as additional data in responses. Subsequently it receives a subset of the root server addresses as additional data in a non-authoritative (referral) response from a root server. This causes the addresses to now be considered non-authoritative (glue) data, which is not eligible for inclusion in responses. The server does have a complete set of root server addresses cached at all times, it just may not include all of them as additional data, depending on whether they were last received as answers or as glue. You can always look up the addresses with explicit queries like "dig a.root-servers.net A". Q: Why don't my zones reload when I do an "rndc reload" or SIGHUP? A: A zone can be updated either by editing zone files and reloading the server or by dynamic update, but not both. If you have enabled dynamic update for a zone using the "allow-update" option, you are not supposed to edit the zone file by hand, and the server will not attempt to reload it. Q: Why is named listening on UDP port other than 53? A: Named uses a system selected port to make queries of other nameservers. This behaviour can be overridden by using query-source to lock down the port and/or address. See also notify-source and transfer-source. Q: I get warning messages like "zone example.com/IN: refresh: failure trying master 1.2.3.4#53: timed out". A: Check that you can make UDP queries from the slave to the master dig +norec example.com soa @1.2.3.4 You could be generating queries faster than the slave can cope with. Lower the serial query rate. serial-query-rate 5; // default 20 Q: I don't get RRSIG's returned when I use "dig +dnssec". A: You need to ensure DNSSEC is enabled (dnssec-enable yes;). Q: Can a NS record refer to a CNAME. A: No. The rules for glue (copies of the *address* records in the parent zones) and additional section processing do not allow it to work. You would have to add both the CNAME and address records (A/AAAA) as glue to the parent zone and have CNAMEs be followed when doing additional section processing to make it work. No nameserver implementation supports either of these requirements. Q: What does "RFC 1918 response from Internet for 0.0.0.10.IN-ADDR.ARPA" mean? A: If the IN-ADDR.ARPA name covered refers to a internal address space you are using then you have failed to follow RFC 1918 usage rules and are leaking queries to the Internet. You should establish your own zones for these addresses to prevent you querying the Internet's name servers for these addresses. Please see for details of the problems you are causing and the counter measures that have had to be deployed. If you are not using these private addresses then a client has queried for them. You can just ignore the messages, get the offending client to stop sending you these messages as they are most probably leaking them or setup your own zones empty zones to serve answers to these queries. zone "10.IN-ADDR.ARPA" { type master; file "empty"; }; zone "16.172.IN-ADDR.ARPA" { type master; file "empty"; }; ... zone "31.172.IN-ADDR.ARPA" { type master; file "empty"; }; zone "168.192.IN-ADDR.ARPA" { type master; file "empty"; }; empty: @ 10800 IN SOA . . ( 1 3600 1200 604800 10800 ) @ 10800 IN NS . Note Future versions of named are likely to do this automatically. Q: Will named be affected by the 2007 changes to daylight savings rules in the US. A: No, so long as the machines internal clock (as reported by "date -u") remains at UTC. The only visible change if you fail to upgrade your OS, if you are in a affected area, will be that log messages will be a hour out during the period where the old rules do not match the new rules. For most OS's this change just means that you need to update the conversion rules from UTC to local time. Normally this involves updating a file in /etc (which sets the default timezone for the machine) and possibly a directory which has all the conversion rules for the world (e.g. /usr/share/zoneinfo). When updating the OS do not forget to update any chroot areas as well. See your OS's documentation for more details. The local timezone conversion rules can also be done on a individual basis by setting the TZ environment variable appropriately. See your OS's documentation for more details. Q: Is there a bugzilla (or other tool) database that mere mortals can have (read-only) access to for bind? A: No. The BIND 9 bug database is kept closed for a number of reasons. These include, but are not limited to, that the database contains proprietory information from people reporting bugs. The database has in the past and may in future contain unfixed bugs which are capable of bringing down most of the Internet's DNS infrastructure. The release pages for each version contain up to date lists of bugs that have been fixed post release. That is as close as we can get to providing a bug database. Q: Why do queries for NSEC3 records fail to return the NSEC3 record? A: NSEC3 records are strictly meta data and can only be returned in the authority section. This is done so that signing the zone using NSEC3 records does not bring names into existence that do not exist in the unsigned version of the zone. 5. Operating-System Specific Questions 5.1. HPUX Q: I get the following error trying to configure BIND: checking if unistd.h or sys/types.h defines fd_set... no configure: error: need either working unistd.h or sys/select.h A: You have attempted to configure BIND with the bundled C compiler. This compiler does not meet the minimum compiler requirements to for building BIND. You need to install a ANSI C compiler and / or teach configure how to find the ANSI C compiler. The later can be done by adjusting the PATH environment variable and / or specifying the compiler via CC. ./configure CC= ... 5.2. Linux Q: Why do I get the following errors: general: errno2result.c:109: unexpected error: general: unable to convert errno to isc_result: 14: Bad address client: UDP client handler shutting down due to fatal receive error: unexpected error A: This is the result of a Linux kernel bug. See: Q: Why does named lock up when it attempts to connect over IPSEC tunnels? A: This is due to a kernel bug where the fact that a socket is marked non-blocking is ignored. It is reported that setting xfrm_larval_drop to 1 helps but this may have negative side effects. See: and . xfrm_larval_drop can be set to 1 by the following procedure: echo "1" > proc/sys/net/core/xfrm_larval_drop Q: Why do I see 5 (or more) copies of named on Linux? A: Linux threads each show up as a process under ps. The approximate number of threads running is n+4, where n is the number of CPUs. Note that the amount of memory used is not cumulative; if each process is using 10M of memory, only a total of 10M is used. Newer versions of Linux's ps command hide the individual threads and require -L to display them. Q: Why does BIND 9 log "permission denied" errors accessing its configuration files or zones on my Linux system even though it is running as root? A: On Linux, BIND 9 drops most of its root privileges on startup. This including the privilege to open files owned by other users. Therefore, if the server is running as root, the configuration files and zone files should also be owned by root. Q: I get the error message "named: capset failed: Operation not permitted" when starting named. A: The capability module, part of "Linux Security Modules/LSM", has not been loaded into the kernel. See insmod(8), modprobe(8). The relevant modules can be loaded by running: modprobe commoncap modprobe capability Q: I'm running BIND on Red Hat Enterprise Linux or Fedora Core - Why can't named update slave zone database files? Why can't named create DDNS journal files or update the master zones from journals? Why can't named create custom log files? A: Red Hat Security Enhanced Linux (SELinux) policy security protections : Red Hat have adopted the National Security Agency's SELinux security policy (see ) and recommendations for BIND security , which are more secure than running named in a chroot and make use of the bind-chroot environment unnecessary . By default, named is not allowed by the SELinux policy to write, create or delete any files EXCEPT in these directories: $ROOTDIR/var/named/slaves $ROOTDIR/var/named/data $ROOTDIR/var/tmp where $ROOTDIR may be set in /etc/sysconfig/named if bind-chroot is installed. The SELinux policy particularly does NOT allow named to modify the $ROOTDIR/var/named directory, the default location for master zone database files. SELinux policy overrules file access permissions - so even if all the files under /var/named have ownership named:named and mode rw-rw-r--, named will still not be able to write or create files except in the directories above, with SELinux in Enforcing mode. So, to allow named to update slave or DDNS zone files, it is best to locate them in $ROOTDIR/var/named/slaves, with named.conf zone statements such as: zone "slave.zone." IN { type slave; file "slaves/slave.zone.db"; ... }; zone "ddns.zone." IN { type master; allow-updates {...}; file "slaves/ddns.zone.db"; }; To allow named to create its cache dump and statistics files, for example, you could use named.conf options statements such as: options { ... dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; ... }; You can also tell SELinux to allow named to update any zone database files, by setting the SELinux tunable boolean parameter 'named_write_master_zones=1', using the system-config-securitylevel GUI, using the 'setsebool' command, or in /etc/selinux/targeted/ booleans. You can disable SELinux protection for named entirely by setting the 'named_disable_trans=1' SELinux tunable boolean parameter. The SELinux named policy defines these SELinux contexts for named: named_zone_t : for zone database files - $ROOTDIR/var/named/* named_conf_t : for named configuration files - $ROOTDIR/etc/{named,rndc}.* named_cache_t: for files modifiable by named - $ROOTDIR/var/{tmp,named/{slaves,data}} If you want to retain use of the SELinux policy for named, and put named files in different locations, you can do so by changing the context of the custom file locations . To create a custom configuration file location, e.g. '/root/ named.conf', to use with the 'named -c' option, do: # chcon system_u:object_r:named_conf_t /root/named.conf To create a custom modifiable named data location, e.g. '/var/log/ named' for a log file, do: # chcon system_u:object_r:named_cache_t /var/log/named To create a custom zone file location, e.g. /root/zones/, do: # chcon system_u:object_r:named_zone_t /root/zones/{.,*} See these man-pages for more information : selinux(8), named_selinux (8), chcon(1), setsebool(8) Q: I'm running BIND on Ubuntu - Why can't named update slave zone database files? Why can't named create DDNS journal files or update the master zones from journals? Why can't named create custom log files? A: Ubuntu uses AppArmor in addition to normal file system permissions to protect the system. Adjust the paths to use those specified in /etc/apparmor.d/ usr.sbin.named or adjust /etc/apparmor.d/usr.sbin.named to allow named to write at the location specified in named.conf. Q: Listening on individual IPv6 interfaces does not work. A: This is usually due to "/proc/net/if_inet6" not being available in the chroot file system. Mount another instance of "proc" in the chroot file system. This can be be made permanent by adding a second instance to /etc/ fstab. proc /proc proc defaults 0 0 proc /var/named/proc proc defaults 0 0 5.3. Windows Q: Zone transfers from my BIND 9 master to my Windows 2000 slave fail. Why? A: This may be caused by a bug in the Windows 2000 DNS server where DNS messages larger than 16K are not handled properly. This can be worked around by setting the option "transfer-format one-answer;". Also check whether your zone contains domain names with embedded spaces or other special characters, like "John\032Doe\213s\032Computer", since such names have been known to cause Windows 2000 slaves to incorrectly reject the zone. Q: I get "Error 1067" when starting named under Windows. A: This is the service manager saying that named exited. You need to examine the Application log in the EventViewer to find out why. Common causes are that you failed to create "named.conf" (usually "C:\ windows\dns\etc\named.conf") or failed to specify the directory in named.conf. options { Directory "C:\windows\dns\etc"; }; 5.4. FreeBSD Q: I have FreeBSD 4.x and "rndc-confgen -a" just sits there. A: /dev/random is not configured. Use rndcontrol(8) to tell the kernel to use certain interrupts as a source of random events. You can make this permanent by setting rand_irqs in /etc/rc.conf. rand_irqs="3 14 15" See also . 5.5. Solaris Q: How do I integrate BIND 9 and Solaris SMF A: Sun has a blog entry describing how to do this. 5.6. Apple Mac OS X Q: How do I run BIND 9 on Apple Mac OS X? A: If you run Tiger(Mac OS 10.4) or later then this is all you need to do: % sudo rndc-confgen > /etc/rndc.conf Copy the key statement from /etc/rndc.conf into /etc/rndc.key, e.g.: key "rndc-key" { algorithm hmac-md5; secret "uvceheVuqf17ZwIcTydddw=="; }; Then start the relevant service: % sudo service org.isc.named start This is persistent upon a reboot, so you will have to do it only once. A: Alternatively you can just generate /etc/rndc.key by running: % sudo rndc-confgen -a Then start the relevant service: % sudo service org.isc.named start Named will look for /etc/rndc.key when it starts if it doesn't have a controls section or the existing controls are missing keys sub-clauses. This is persistent upon a reboot, so you will have to do it only once. bind-9.6-ESV-R6/FAQ.xml000644 024064 023255 00000131177 11734112744 014467 0ustar00eachsweng000000 000000
Frequently Asked Questions about BIND 9 2004 2005 2006 2007 2008 2009 2010 2012 Internet Systems Consortium, Inc. ("ISC") 2000 2001 2002 2003 Internet Software Consortium. Compilation and Installation Questions I'm trying to compile BIND 9, and "make" is failing due to files not being found. Why? Using a parallel or distributed "make" to build BIND 9 is not supported, and doesn't work. If you are using one of these, use normal make or gmake instead. Isn't "make install" supposed to generate a default named.conf? Short Answer: No. Long Answer: There really isn't a default configuration which fits any site perfectly. There are lots of decisions that need to be made and there is no consensus on what the defaults should be. For example FreeBSD uses /etc/namedb as the location where the configuration files for named are stored. Others use /var/named. What addresses to listen on? For a laptop on the move a lot you may only want to listen on the loop back interfaces. Who do you offer recursive service to? Is there are firewall to consider? If so is it stateless or stateful. Are you directly on the Internet? Are you on a private network? Are you on a NAT'd network? The answers to all these questions change how you configure even a caching name server. Configuration and Setup Questions Why does named log the warning message no TTL specified - using SOA MINTTL instead? Your zone file is illegal according to RFC1035. It must either have a line like: $TTL 86400 at the beginning, or the first record in it must have a TTL field, like the "84600" in this example: example.com. 86400 IN SOA ns hostmaster ( 1 3600 1800 1814400 3600 ) Why do I get errors like dns_zone_load: zone foo/IN: loading master file bar: ran out of space? This is often caused by TXT records with missing close quotes. Check that all TXT records containing quoted strings have both open and close quotes. How do I restrict people from looking up the server version? Put a "version" option containing something other than the real version in the "options" section of named.conf. Note doing this will not prevent attacks and may impede people trying to diagnose problems with your server. Also it is possible to "fingerprint" nameservers to determine their version. How do I restrict only remote users from looking up the server version? The following view statement will intercept lookups as the internal view that holds the version information will be matched last. The caveats of the previous answer still apply, of course. view "chaos" chaos { match-clients { <those to be refused>; }; allow-query { none; }; zone "." { type hint; file "/dev/null"; // or any empty file }; }; What do no source of entropy found or could not open entropy source foo mean? The server requires a source of entropy to perform certain operations, mostly DNSSEC related. These messages indicate that you have no source of entropy. On systems with /dev/random or an equivalent, it is used by default. A source of entropy can also be defined using the random-device option in named.conf. I'm trying to use TSIG to authenticate dynamic updates or zone transfers. I'm sure I have the keys set up correctly, but the server is rejecting the TSIG. Why? This may be a clock skew problem. Check that the the clocks on the client and server are properly synchronised (e.g., using ntp). I see a log message like the following. Why? couldn't open pid file '/var/run/named.pid': Permission denied You are most likely running named as a non-root user, and that user does not have permission to write in /var/run. The common ways of fixing this are to create a /var/run/named directory owned by the named user and set pid-file to "/var/run/named/named.pid", or set pid-file to "named.pid", which will put the file in the directory specified by the directory option (which, in this case, must be writable by the named user). I can query the nameserver from the nameserver but not from other machines. Why? This is usually the result of the firewall configuration stopping the queries and / or the replies. How can I make a server a slave for both an internal and an external view at the same time? When I tried, both views on the slave were transferred from the same view on the master. You will need to give the master and slave multiple IP addresses and use those to make sure you reach the correct view on the other machine. Master: 10.0.1.1 (internal), 10.0.1.2 (external, IP alias) internal: match-clients { !10.0.1.2; !10.0.1.4; 10.0.1/24; }; notify-source 10.0.1.1; transfer-source 10.0.1.1; query-source address 10.0.1.1; external: match-clients { any; }; recursion no; // don't offer recursion to the world notify-source 10.0.1.2; transfer-source 10.0.1.2; query-source address 10.0.1.2; Slave: 10.0.1.3 (internal), 10.0.1.4 (external, IP alias) internal: match-clients { !10.0.1.2; !10.0.1.4; 10.0.1/24; }; notify-source 10.0.1.3; transfer-source 10.0.1.3; query-source address 10.0.1.3; external: match-clients { any; }; recursion no; // don't offer recursion to the world notify-source 10.0.1.4; transfer-source 10.0.1.4; query-source address 10.0.1.4; You put the external address on the alias so that all the other dns clients on these boxes see the internal view by default. BIND 9.3 and later: Use TSIG to select the appropriate view. Master 10.0.1.1: key "external" { algorithm hmac-sha256; secret "xxxxxxxxxxxxxxxxxxxxxxxx"; }; view "internal" { match-clients { !key external; // reject message ment for the // external view. 10.0.1/24; }; // accept from these addresses. ... }; view "external" { match-clients { key external; any; }; server 10.0.1.2 { keys external; }; // tag messages from the // external view to the // other servers for the // view. recursion no; ... }; Slave 10.0.1.2: key "external" { algorithm hmac-sha256; secret "xxxxxxxxxxxxxxxxxxxxxxxx"; }; view "internal" { match-clients { !key external; 10.0.1/24; }; ... }; view "external" { match-clients { key external; any; }; server 10.0.1.1 { keys external; }; recursion no; ... }; I get error messages like multiple RRs of singleton type and CNAME and other data when transferring a zone. What does this mean? These indicate a malformed master zone. You can identify the exact records involved by transferring the zone using dig then running named-checkzone on it. dig axfr example.com @master-server > tmp named-checkzone example.com tmp A CNAME record cannot exist with the same name as another record except for the DNSSEC records which prove its existence (NSEC). RFC 1034, Section 3.6.2: If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types. I get error messages like named.conf:99: unexpected end of input where 99 is the last line of named.conf. There are unbalanced quotes in named.conf. Some text editors (notepad and wordpad) fail to put a line title indication (e.g. CR/LF) on the last line of a text file. This can be fixed by "adding" a blank line to the end of the file. Named expects to see EOF immediately after EOL and treats text files where this is not met as truncated. How do I share a dynamic zone between multiple views? You choose one view to be master and the second a slave and transfer the zone between views. Master 10.0.1.1: key "external" { algorithm hmac-sha256; secret "xxxxxxxxxxxxxxxxxxxxxxxx"; }; key "mykey" { algorithm hmac-sha256; secret "yyyyyyyyyyyyyyyyyyyyyyyy"; }; view "internal" { match-clients { !key external; 10.0.1/24; }; server 10.0.1.1 { /* Deliver notify messages to external view. */ keys { external; }; }; zone "example.com" { type master; file "internal/example.db"; allow-update { key mykey; }; also-notify { 10.0.1.1; }; }; }; view "external" { match-clients { key external; any; }; zone "example.com" { type slave; file "external/example.db"; masters { 10.0.1.1; }; transfer-source 10.0.1.1; // allow-update-forwarding { any; }; // allow-notify { ... }; }; }; I get a error message like zone wireless.ietf56.ietf.org/IN: loading master file primaries/wireless.ietf56.ietf.org: no owner. This error is produced when a line in the master file contains leading white space (tab/space) but the is no current record owner name to inherit the name from. Usually this is the result of putting white space before a comment, forgetting the "@" for the SOA record, or indenting the master file. Why are my logs in GMT (UTC). You are running chrooted (-t) and have not supplied local timezone information in the chroot area. FreeBSD: /etc/localtime Solaris: /etc/TIMEZONE and /usr/share/lib/zoneinfo OSF: /etc/zoneinfo/localtime See also tzset(3) and zic(8). I get rndc: connect failed: connection refused when I try to run rndc. This is usually a configuration error. First ensure that named is running and no errors are being reported at startup (/var/log/messages or equivalent). Running "named -g <usual arguments>" from a title can help at this point. Secondly ensure that named is configured to use rndc either by "rndc-confgen -a", rndc-confgen or manually. The Administrators Reference manual has details on how to do this. Old versions of rndc-confgen used localhost rather than 127.0.0.1 in /etc/rndc.conf for the default server. Update /etc/rndc.conf if necessary so that the default server listed in /etc/rndc.conf matches the addresses used in named.conf. "localhost" has two address (127.0.0.1 and ::1). If you use "rndc-confgen -a" and named is running with -t or -u ensure that /etc/rndc.conf has the correct ownership and that a copy is in the chroot area. You can do this by re-running "rndc-confgen -a" with appropriate -t and -u arguments. I get transfer of 'example.net/IN' from 192.168.4.12#53: failed while receiving responses: permission denied error messages. These indicate a filesystem permission error preventing named creating / renaming the temporary file. These will usually also have other associated error messages like "dumping master file: sl/tmp-XXXX5il3sQ: open: permission denied" Named needs write permission on the directory containing the file. Named writes the new cache file to a temporary file then renames it to the name specified in named.conf to ensure that the contents are always complete. This is to prevent named loading a partial zone in the event of power failure or similar interrupting the write of the master file. Note file names are relative to the directory specified in options and any chroot directory ([<chroot dir>/][<options dir>]). If named is invoked as "named -t /chroot/DNS" with the following named.conf then "/chroot/DNS/var/named/sl" needs to be writable by the user named is running as. options { directory "/var/named"; }; zone "example.net" { type slave; file "sl/example.net"; masters { 192.168.4.12; }; }; I want to forward all DNS queries from my caching nameserver to another server. But there are some domains which have to be served locally, via rbldnsd. How do I achieve this ? options { forward only; forwarders { <ip.of.primary.nameserver>; }; }; zone "sbl-xbl.spamhaus.org" { type forward; forward only; forwarders { <ip.of.rbldns.server> port 530; }; }; zone "list.dsbl.org" { type forward; forward only; forwarders { <ip.of.rbldns.server> port 530; }; }; Can you help me understand how BIND 9 uses memory to store DNS zones? Some times it seems to take several times the amount of memory it needs to store the zone. When reloading a zone named my have multiple copies of the zone in memory at one time. The zone it is serving and the one it is loading. If reloads are ultra fast it can have more still. e.g. Ones that are transferring out, the one that it is serving and the one that is loading. BIND 8 destroyed the zone before loading and also killed off outgoing transfers of the zone. The new strategy allows slaves to get copies of the new zone regardless of how often the master is loaded compared to the transfer time. The slave might skip some intermediate versions but the transfers will complete and it will keep reasonably in sync with the master. The new strategy also allows the master to recover from syntax and other errors in the master file as it still has an in-core copy of the old contents. I want to use IPv6 locally but I don't have a external IPv6 connection. External lookups are slow. You can use server clauses to stop named making external lookups over IPv6. server fd81:ec6c:bd62::/48 { bogus no; }; // site ULA prefix server ::/0 { bogus yes; }; Operations Questions How to change the nameservers for a zone? Step 1: Ensure all nameservers, new and old, are serving the same zone content. Step 2: Work out the maximum TTL of the NS RRset in the parent and child zones. This is the time it will take caches to be clear of a particular version of the NS RRset. If you are just removing nameservers you can skip to Step 6. Step 3: Add new nameservers to the NS RRset for the zone and wait until all the servers for the zone are answering with this new NS RRset. Step 4: Inform the parent zone of the new NS RRset then wait for all the parent servers to be answering with the new NS RRset. Step 5: Wait for cache to be clear of the old NS RRset. See Step 2 for how long. If you are just adding nameservers you are done. Step 6: Remove any old nameservers from the zones NS RRset and wait for all the servers for the zone to be serving the new NS RRset. Step 7: Inform the parent zone of the new NS RRset then wait for all the parent servers to be answering with the new NS RRset. Step 8: Wait for cache to be clear of the old NS RRset. See Step 2 for how long. Step 9: Turn off the old nameservers or remove the zone entry from the configuration of the old nameservers. Step 10: Increment the serial number and wait for the change to be visible in all nameservers for the zone. This ensures that zone transfers are still working after the old servers are decommissioned. Note: the above procedure is designed to be transparent to dns clients. Decommissioning the old servers too early will result in some clients not being able to look up answers in the zone. Note: while it is possible to run the addition and removal stages together it is not recommended. General Questions I keep getting log messages like the following. Why? Dec 4 23:47:59 client 10.0.0.1#1355: updating zone 'example.com/IN': update failed: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) DNS updates allow the update request to test to see if certain conditions are met prior to proceeding with the update. The message above is saying that conditions were not met and the update is not proceeding. See doc/rfc/rfc2136.txt for more details on prerequisites. I keep getting log messages like the following. Why? Jun 21 12:00:00.000 client 10.0.0.1#1234: update denied Someone is trying to update your DNS data using the RFC2136 Dynamic Update protocol. Windows 2000 machines have a habit of sending dynamic update requests to DNS servers without being specifically configured to do so. If the update requests are coming from a Windows 2000 machine, see <http://support.microsoft.com/support/kb/articles/q246/8/04.asp> for information about how to turn them off. When I do a "dig . ns", many of the A records for the root servers are missing. Why? This is normal and harmless. It is a somewhat confusing side effect of the way BIND 9 does RFC2181 trust ranking and of the efforts BIND 9 makes to avoid promoting glue into answers. When BIND 9 first starts up and primes its cache, it receives the root server addresses as additional data in an authoritative response from a root server, and these records are eligible for inclusion as additional data in responses. Subsequently it receives a subset of the root server addresses as additional data in a non-authoritative (referral) response from a root server. This causes the addresses to now be considered non-authoritative (glue) data, which is not eligible for inclusion in responses. The server does have a complete set of root server addresses cached at all times, it just may not include all of them as additional data, depending on whether they were last received as answers or as glue. You can always look up the addresses with explicit queries like "dig a.root-servers.net A". Why don't my zones reload when I do an "rndc reload" or SIGHUP? A zone can be updated either by editing zone files and reloading the server or by dynamic update, but not both. If you have enabled dynamic update for a zone using the "allow-update" option, you are not supposed to edit the zone file by hand, and the server will not attempt to reload it. Why is named listening on UDP port other than 53? Named uses a system selected port to make queries of other nameservers. This behaviour can be overridden by using query-source to lock down the port and/or address. See also notify-source and transfer-source. I get warning messages like zone example.com/IN: refresh: failure trying master 1.2.3.4#53: timed out. Check that you can make UDP queries from the slave to the master dig +norec example.com soa @1.2.3.4 You could be generating queries faster than the slave can cope with. Lower the serial query rate. serial-query-rate 5; // default 20 I don't get RRSIG's returned when I use "dig +dnssec". You need to ensure DNSSEC is enabled (dnssec-enable yes;). Can a NS record refer to a CNAME. No. The rules for glue (copies of the *address* records in the parent zones) and additional section processing do not allow it to work. You would have to add both the CNAME and address records (A/AAAA) as glue to the parent zone and have CNAMEs be followed when doing additional section processing to make it work. No nameserver implementation supports either of these requirements. What does RFC 1918 response from Internet for 0.0.0.10.IN-ADDR.ARPA mean? If the IN-ADDR.ARPA name covered refers to a internal address space you are using then you have failed to follow RFC 1918 usage rules and are leaking queries to the Internet. You should establish your own zones for these addresses to prevent you querying the Internet's name servers for these addresses. Please see <http://as112.net/> for details of the problems you are causing and the counter measures that have had to be deployed. If you are not using these private addresses then a client has queried for them. You can just ignore the messages, get the offending client to stop sending you these messages as they are most probably leaking them or setup your own zones empty zones to serve answers to these queries. zone "10.IN-ADDR.ARPA" { type master; file "empty"; }; zone "16.172.IN-ADDR.ARPA" { type master; file "empty"; }; ... zone "31.172.IN-ADDR.ARPA" { type master; file "empty"; }; zone "168.192.IN-ADDR.ARPA" { type master; file "empty"; }; empty: @ 10800 IN SOA <name-of-server>. <contact-email>. ( 1 3600 1200 604800 10800 ) @ 10800 IN NS <name-of-server>. Future versions of named are likely to do this automatically. Will named be affected by the 2007 changes to daylight savings rules in the US. No, so long as the machines internal clock (as reported by "date -u") remains at UTC. The only visible change if you fail to upgrade your OS, if you are in a affected area, will be that log messages will be a hour out during the period where the old rules do not match the new rules. For most OS's this change just means that you need to update the conversion rules from UTC to local time. Normally this involves updating a file in /etc (which sets the default timezone for the machine) and possibly a directory which has all the conversion rules for the world (e.g. /usr/share/zoneinfo). When updating the OS do not forget to update any chroot areas as well. See your OS's documentation for more details. The local timezone conversion rules can also be done on a individual basis by setting the TZ environment variable appropriately. See your OS's documentation for more details. Is there a bugzilla (or other tool) database that mere mortals can have (read-only) access to for bind? No. The BIND 9 bug database is kept closed for a number of reasons. These include, but are not limited to, that the database contains proprietory information from people reporting bugs. The database has in the past and may in future contain unfixed bugs which are capable of bringing down most of the Internet's DNS infrastructure. The release pages for each version contain up to date lists of bugs that have been fixed post release. That is as close as we can get to providing a bug database. Why do queries for NSEC3 records fail to return the NSEC3 record? NSEC3 records are strictly meta data and can only be returned in the authority section. This is done so that signing the zone using NSEC3 records does not bring names into existence that do not exist in the unsigned version of the zone. Operating-System Specific Questions HPUX I get the following error trying to configure BIND: checking if unistd.h or sys/types.h defines fd_set... no configure: error: need either working unistd.h or sys/select.h You have attempted to configure BIND with the bundled C compiler. This compiler does not meet the minimum compiler requirements to for building BIND. You need to install a ANSI C compiler and / or teach configure how to find the ANSI C compiler. The later can be done by adjusting the PATH environment variable and / or specifying the compiler via CC. ./configure CC=<compiler> ... Linux Why do I get the following errors: general: errno2result.c:109: unexpected error: general: unable to convert errno to isc_result: 14: Bad address client: UDP client handler shutting down due to fatal receive error: unexpected error This is the result of a Linux kernel bug. See: <http://marc.theaimsgroup.com/?l=linux-netdev&m=113081708031466&w=2> Why does named lock up when it attempts to connect over IPSEC tunnels? This is due to a kernel bug where the fact that a socket is marked non-blocking is ignored. It is reported that setting xfrm_larval_drop to 1 helps but this may have negative side effects. See: <https://bugzilla.redhat.com/show_bug.cgi?id=427629> and <http://lkml.org/lkml/2007/12/4/260>. xfrm_larval_drop can be set to 1 by the following procedure: echo "1" > proc/sys/net/core/xfrm_larval_drop Why do I see 5 (or more) copies of named on Linux? Linux threads each show up as a process under ps. The approximate number of threads running is n+4, where n is the number of CPUs. Note that the amount of memory used is not cumulative; if each process is using 10M of memory, only a total of 10M is used. Newer versions of Linux's ps command hide the individual threads and require -L to display them. Why does BIND 9 log permission denied errors accessing its configuration files or zones on my Linux system even though it is running as root? On Linux, BIND 9 drops most of its root privileges on startup. This including the privilege to open files owned by other users. Therefore, if the server is running as root, the configuration files and zone files should also be owned by root. I get the error message named: capset failed: Operation not permitted when starting named. The capability module, part of "Linux Security Modules/LSM", has not been loaded into the kernel. See insmod(8), modprobe(8). The relevant modules can be loaded by running: modprobe commoncap modprobe capability I'm running BIND on Red Hat Enterprise Linux or Fedora Core - Why can't named update slave zone database files? Why can't named create DDNS journal files or update the master zones from journals? Why can't named create custom log files? Red Hat Security Enhanced Linux (SELinux) policy security protections : Red Hat have adopted the National Security Agency's SELinux security policy (see <http://www.nsa.gov/selinux>) and recommendations for BIND security , which are more secure than running named in a chroot and make use of the bind-chroot environment unnecessary . By default, named is not allowed by the SELinux policy to write, create or delete any files EXCEPT in these directories: $ROOTDIR/var/named/slaves $ROOTDIR/var/named/data $ROOTDIR/var/tmp where $ROOTDIR may be set in /etc/sysconfig/named if bind-chroot is installed. The SELinux policy particularly does NOT allow named to modify the $ROOTDIR/var/named directory, the default location for master zone database files. SELinux policy overrules file access permissions - so even if all the files under /var/named have ownership named:named and mode rw-rw-r--, named will still not be able to write or create files except in the directories above, with SELinux in Enforcing mode. So, to allow named to update slave or DDNS zone files, it is best to locate them in $ROOTDIR/var/named/slaves, with named.conf zone statements such as: zone "slave.zone." IN { type slave; file "slaves/slave.zone.db"; ... }; zone "ddns.zone." IN { type master; allow-updates {...}; file "slaves/ddns.zone.db"; }; To allow named to create its cache dump and statistics files, for example, you could use named.conf options statements such as: options { ... dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; ... }; You can also tell SELinux to allow named to update any zone database files, by setting the SELinux tunable boolean parameter 'named_write_master_zones=1', using the system-config-securitylevel GUI, using the 'setsebool' command, or in /etc/selinux/targeted/booleans. You can disable SELinux protection for named entirely by setting the 'named_disable_trans=1' SELinux tunable boolean parameter. The SELinux named policy defines these SELinux contexts for named: named_zone_t : for zone database files - $ROOTDIR/var/named/* named_conf_t : for named configuration files - $ROOTDIR/etc/{named,rndc}.* named_cache_t: for files modifiable by named - $ROOTDIR/var/{tmp,named/{slaves,data}} If you want to retain use of the SELinux policy for named, and put named files in different locations, you can do so by changing the context of the custom file locations . To create a custom configuration file location, e.g. '/root/named.conf', to use with the 'named -c' option, do: # chcon system_u:object_r:named_conf_t /root/named.conf To create a custom modifiable named data location, e.g. '/var/log/named' for a log file, do: # chcon system_u:object_r:named_cache_t /var/log/named To create a custom zone file location, e.g. /root/zones/, do: # chcon system_u:object_r:named_zone_t /root/zones/{.,*} See these man-pages for more information : selinux(8), named_selinux(8), chcon(1), setsebool(8) I'm running BIND on Ubuntu - Why can't named update slave zone database files? Why can't named create DDNS journal files or update the master zones from journals? Why can't named create custom log files? Ubuntu uses AppArmor <http://en.wikipedia.org/wiki/AppArmor> in addition to normal file system permissions to protect the system. Adjust the paths to use those specified in /etc/apparmor.d/usr.sbin.named or adjust /etc/apparmor.d/usr.sbin.named to allow named to write at the location specified in named.conf. Listening on individual IPv6 interfaces does not work. This is usually due to "/proc/net/if_inet6" not being available in the chroot file system. Mount another instance of "proc" in the chroot file system. This can be be made permanent by adding a second instance to /etc/fstab. proc /proc proc defaults 0 0 proc /var/named/proc proc defaults 0 0 Windows Zone transfers from my BIND 9 master to my Windows 2000 slave fail. Why? This may be caused by a bug in the Windows 2000 DNS server where DNS messages larger than 16K are not handled properly. This can be worked around by setting the option "transfer-format one-answer;". Also check whether your zone contains domain names with embedded spaces or other special characters, like "John\032Doe\213s\032Computer", since such names have been known to cause Windows 2000 slaves to incorrectly reject the zone. I get Error 1067 when starting named under Windows. This is the service manager saying that named exited. You need to examine the Application log in the EventViewer to find out why. Common causes are that you failed to create "named.conf" (usually "C:\windows\dns\etc\named.conf") or failed to specify the directory in named.conf. options { Directory "C:\windows\dns\etc"; }; FreeBSD I have FreeBSD 4.x and "rndc-confgen -a" just sits there. /dev/random is not configured. Use rndcontrol(8) to tell the kernel to use certain interrupts as a source of random events. You can make this permanent by setting rand_irqs in /etc/rc.conf. rand_irqs="3 14 15" See also <http://people.freebsd.org/~dougb/randomness.html>. Solaris How do I integrate BIND 9 and Solaris SMF Sun has a blog entry describing how to do this. <http://blogs.sun.com/roller/page/anay/Weblog?catname=%2FSolaris> Apple Mac OS X How do I run BIND 9 on Apple Mac OS X? If you run Tiger(Mac OS 10.4) or later then this is all you need to do: % sudo rndc-confgen > /etc/rndc.conf Copy the key statement from /etc/rndc.conf into /etc/rndc.key, e.g.: key "rndc-key" { algorithm hmac-md5; secret "uvceheVuqf17ZwIcTydddw=="; }; Then start the relevant service: % sudo service org.isc.named start This is persistent upon a reboot, so you will have to do it only once. Alternatively you can just generate /etc/rndc.key by running: % sudo rndc-confgen -a Then start the relevant service: % sudo service org.isc.named start Named will look for /etc/rndc.key when it starts if it doesn't have a controls section or the existing controls are missing keys sub-clauses. This is persistent upon a reboot, so you will have to do it only once.
bind-9.6-ESV-R6/KNOWN-DEFECTS000644 024064 023255 00000001516 11734112744 015221 0ustar00eachsweng000000 000000 dnssec-signzone was designed so that it could sign a zone partially, using only a subset of the DNSSEC keys needed to produce a fully-signed zone. This permits a zone administrator, for example, to sign a zone with one key on one machine, move the resulting partially-signed zone to a second machine, and sign it again with a second key. An unfortunate side-effect of this flexibility is that dnssec-signzone does not check to make sure it's signing a zone with any valid keys at all. An attempt to sign a zone without any keys will appear to succeed, producing a "signed" zone with no signatures. There is no warning issued when a zone is not signed. This will be corrected in a future release. In the meantime, ISC recommends examining the output of dnssec-signzone to confirm that the zone is properly signed by all keys before using it. bind-9.6-ESV-R6/Makefile.in000644 024064 023255 00000004256 11734112744 015400 0ustar00eachsweng000000 000000 # Copyright (C) 2004-2009, 2011, 2012 Internet Systems Consortium, Inc.

A secure zone can be using NSEC or NSEC3. To move a zone from insecure to secure you need to configure named so that it can see the K* files which contain the public and private parts of the keys that will be used to sign the zone. These files will have been generated by dnssec-keygen. You can do this by placing them in the key-directory as specified in named.conf. zone example.net { type master; allow-update { .... }; file "dynamic/example.net/example.net"; key-directory "dynamic/example.net"; }; Assuming one KSK and one ZSK DNSKEY key have been generated. Then this will cause the zone to be signed with the ZSK and the DNSKEY RRset to be signed with the KSK DNSKEY. A NSEC chain will also be generated as part of the initial signing process. % nsupdate > ttl 3600 > update add example.net DNSKEY 256 3 7 AwEAAZn17pUF0KpbPA2c7Gz76Vb18v0teKT3EyAGfBfL8eQ8al35zz3Y I1m/SAQBxIqMfLtIwqWPdgthsu36azGQAX8= > update add example.net DNSKEY 257 3 7 AwEAAd/7odU/64o2LGsifbLtQmtO8dFDtTAZXSX2+X3e/UNlq9IHq3Y0 XtC0Iuawl/qkaKVxXe2lo8Ct+dM6UehyCqk= > send While the update request will complete almost immediately the zone will not be completely signed until named has had time to walk the zone and generate the NSEC and RRSIG records. Initially the NSEC record at the zone apex will have the OPT bit set. When the NSEC chain is complete the OPT bit will be cleared. Additionally when the zone is fully signed the private type (default TYPE65534) records will have a non zero value for the final octet. The private type record has 5 octets. algorithm (octet 1) key id in network order (octet 2 and 3) removal flag (octet 4) complete flag (octet 5) If you wish to go straight to a secure zone using NSEC3 you should also add a NSEC3PARAM record to the update request with the flags field set to indicate whether the NSEC3 chain will have the OPTOUT bit set or not. % nsupdate > ttl 3600 > update add example.net DNSKEY 256 3 7 AwEAAZn17pUF0KpbPA2c7Gz76Vb18v0teKT3EyAGfBfL8eQ8al35zz3Y I1m/SAQBxIqMfLtIwqWPdgthsu36azGQAX8= > update add example.net DNSKEY 257 3 7 AwEAAd/7odU/64o2LGsifbLtQmtO8dFDtTAZXSX2+X3e/UNlq9IHq3Y0 XtC0Iuawl/qkaKVxXe2lo8Ct+dM6UehyCqk= > update add example.net NSEC3PARAM 1 1 100 1234567890 > send Again the update request will complete almost immediately however the NSEC3PARAM record will have additional flag bits set indicating that the NSEC3 chain is under construction. When the NSEC3 chain is complete the flags field will be set to zero. While the initial signing and NSEC/NSEC3 chain generation is happening other updates are possible. DNSKEY roll overs via UPDATE It is possible to perform key rollovers via update. You need to add the K* files for the new keys so that named can find them. You can then add the new DNSKEY RRs via update. Named will then cause the zone to be signed with the new keys. When the signing is complete the private type records will be updated so that the last octet is non zero. If this is for a KSK you need to inform the parent and any trust anchor repositories of the new KSK. You should then wait for the maximum TLL in the zone before removing the old DNSKEY. If it is a KSK that is being updated you also need to wait for the DS RRset in the parent to be updated and its TTL to expire. This ensures that all clients will be able to verify at least a signature when you remove the old DNSKEY. The old DNSKEY can be removed via UPDATE. Take care to specify the correct key. Named will clean out any signatures generated by the old key after the update completes. NSEC3PARAM rollovers via UPDATE. Add the new NSEC3PARAM record via update. When the new NSEC3 chain has been generated the NSEC3PARAM flag field will be zero. At this point you can remove the old NSEC3PARAM record. The old chain will be removed after the update request completes. Converting from NSEC to NSEC3 To do this you just need to add a NSEC3PARAM record. When the conversion is complete the NSEC chain will have been removed and the NSEC3PARAM record will have a zero flag field. The NSEC3 chain will be generated before the NSEC chain is destroyed. Converting from NSEC3 to NSEC To do this remove all NSEC3PARAM records with a zero flag field. The NSEC chain will be generated before the NSEC3 chain is removed. Converting from secure to insecure To do this remove all the DNSKEY records. Any NSEC or NSEC3 chains will be removed as well as associated NSEC3PARAM records. This will take place after the update requests completes. Periodic re-signing. Named will periodically re-sign RRsets which have not been re-signed as a result of some update action. The signature lifetimes will be adjusted so as to spread the re-sign load over time rather than all at once. NSEC3 and OPTOUT Named only supports creating new NSEC3 chains where all the NSEC3 records in the zone have the same OPTOUT state. Named supports UPDATES to zones where the NSEC3 records in the chain have mixed OPTOUT state. Named does not support changing the OPTOUT state of an individual NSEC3 record, the entire chain needs to be changed if the OPTOUT state of an individual NSEC3 needs to be changed. bind-9.6-ESV-R6/README000644 024064 023255 00000050116 11734112744 014207 0ustar00eachsweng000000 000000 BIND 9 BIND version 9 is a major rewrite of nearly all aspects of the underlying BIND architecture. Some of the important features of BIND 9 are: - DNS Security DNSSEC (signed zones) TSIG (signed DNS requests) - IP version 6 Answers DNS queries on IPv6 sockets IPv6 resource records (AAAA) Experimental IPv6 Resolver Library - DNS Protocol Enhancements IXFR, DDNS, Notify, EDNS0 Improved standards conformance - Views One server process can provide multiple "views" of the DNS namespace, e.g. an "inside" view to certain clients, and an "outside" view to others. - Multiprocessor Support - Improved Portability Architecture BIND version 9 development has been underwritten by the following organizations: Sun Microsystems, Inc. Hewlett Packard Compaq Computer Corporation IBM Process Software Corporation Silicon Graphics, Inc. Network Associates, Inc. U.S. Defense Information Systems Agency USENIX Association Stichting NLnet - NLnet Foundation Nominum, Inc. For a detailed list of user-visible changes from previous releases, see the CHANGES file. For up-to-date release notes and errata, see http://www.isc.org/software/bind9/releasenotes BIND 9.6-ESV-R6 (Extended Support Version) BIND 9.6-ESV-R6 includes a number of bug fixes and prevents a security problem described in CVE-2011-4313 BIND 9.6-ESV-R5 (Extended Support Version) BIND 9.4-ESV-R5 is a maintenance release, fixing bugs in BIND 9.6-ESV-R4. BIND 9.6.3/BIND 9.6-ESV-R4 BIND 9.6.3/BIND 9.6-ESV-R4 is a maintenance release, fixing bugs in 9.6.2. BIND 9.6.2 BIND 9.6.2 is a maintenance release, fixing bugs in 9.6.1. It also introduces support for the SHA-2 DNSSEC algorithms, RSASHA256 and RSASHA512. Known issues in this release: - A validating resolver that has been incorrectly configured with an invalid trust anchor will be unable to resolve names covered by that trust anchor. In all current versions of BIND 9, such a resolver will also generate significant unnecessary DNS traffic while trying to validate. The latter problem will be addressed in future BIND 9 releases. In the meantime, to avoid these problems, exercise caution when configuring "trusted-keys": make sure all keys are correct and current when you add them, and update your configuration in a timely manner when keys roll over. BIND 9.6.1 BIND 9.6.1 is a maintenance release, fixing bugs in 9.6.0. BIND 9.6.0 BIND 9.6.0 includes a number of changes from BIND 9.5 and earlier releases, including: Full NSEC3 support Automatic zone re-signing New update-policy methods tcp-self and 6to4-self The BIND 8 resolver library, libbind, has been removed from the BIND 9 distribution and is now available as a separate download. Change the default pid file location from /var/run to /var/run/{named,lwresd} for improved chroot/setuid support. BIND 9.5.0 BIND 9.5.0 has a number of new features over 9.4, including: GSS-TSIG support (RFC 3645). DHCID support. Experimental http server and statistics support for named via xml. More detailed statistics counters including those supported in BIND 8. Faster ACL processing. Use Doxygen to generate internal documentation. Efficient LRU cache-cleaning mechanism. NSID support. BIND 9.4.0 BIND 9.4.0 has a number of new features over 9.3, including: Implemented "additional section caching (or acache)", an internal cache framework for additional section content to improve response performance. Several configuration options were provided to control the behavior. New notify type 'master-only'. Enable notify for master zones only. Accept 'notify-source' style syntax for query-source. rndc now allows addresses to be set in the server clauses. New option "allow-query-cache". This lets "allow-query" be used to specify the default zone access level rather than having to have every zone override the global value. "allow-query-cache" can be set at both the options and view levels. If "allow-query-cache" is not set then "allow-recursion" is used if set, otherwise "allow-query" is used if set unless "recursion no;" is set in which case "none;" is used, otherwise the default (localhost; localnets;) is used. rndc: the source address can now be specified. ixfr-from-differences now takes master and slave in addition to yes and no at the options and view levels. Allow the journal's name to be changed via named.conf. 'rndc notify zone [class [view]]' resend the NOTIFY messages for the specified zone. 'dig +trace' now randomly selects the next servers to try. Report if there is a bad delegation. Improve check-names error messages. Make public the function to read a key file, dst_key_read_public(). dig now returns the byte count for axfr/ixfr. allow-update is now settable at the options / view level. named-checkconf now checks the logging configuration. host now can turn on memory debugging flags with '-m'. Don't send notify messages to self. Perform sanity checks on NS records which refer to 'in zone' names. New zone option "notify-delay". Specify a minimum delay between sets of NOTIFY messages. Extend adjusting TTL warning messages. Named and named-checkzone can now both check for non-terminal wildcard records. "rndc freeze/thaw" now freezes/thaws all zones. named-checkconf now check acls to verify that they only refer to existing acls. The server syntax has been extended to support a range of servers. Report differences between hints and real NS rrset and associated address records. Preserve the case of domain names in rdata during zone transfers. Restructured the data locking framework using architecture dependent atomic operations (when available), improving response performance on multi-processor machines significantly. x86, x86_64, alpha, powerpc, and mips are currently supported. UNIX domain controls are now supported. Add support for additional zone file formats for improving loading performance. The masterfile-format option in named.conf can be used to specify a non-default format. A separate command named-compilezone was provided to generate zone files in the new format. Additionally, the -I and -O options for dnssec-signzone specify the input and output formats. dnssec-signzone can now randomize signature end times (dnssec-signzone -j jitter). Add support for CH A record. Add additional zone data constancy checks. named-checkzone has extended checking of NS, MX and SRV record and the hosts they reference. named has extended post zone load checks. New zone options: check-mx and integrity-check. edns-udp-size can now be overridden on a per server basis. dig can now specify the EDNS version when making a query. Added framework for handling multiple EDNS versions. Additional memory debugging support to track size and mctx arguments. Detect duplicates of UDP queries we are recursing on and drop them. New stats category "duplicates". "USE INTERNAL MALLOC" is now runtime selectable. The lame cache is now done on a basis as some servers only appear to be lame for certain query types. Limit the number of recursive clients that can be waiting for a single query () to resolve. New options clients-per-query and max-clients-per-query. dig: report the number of extra bytes still left in the packet after processing all the records. Support for IPSECKEY rdata type. Raise the UDP recieve buffer size to 32k if it is less than 32k. x86 and x86_64 now have seperate atomic locking implementations. named-checkconf now validates update-policy entries. Attempt to make the amount of work performed in a iteration self tuning. The covers nodes clean from the cache per iteration, nodes written to disk when rewriting a master file and nodes destroyed per iteration when destroying a zone or a cache. ISC string copy API. Automatic empty zone creation for D.F.IP6.ARPA and friends. Note: RFC 1918 zones are not yet covered by this but are likely to be in a future release. New options: empty-server, empty-contact, empty-zones-enable and disable-empty-zone. dig now has a '-q queryname' and '+showsearch' options. host/nslookup now continue (default)/fail on SERVFAIL. dig now warns if 'RA' is not set in the answer when 'RD' was set in the query. host/nslookup skip servers that fail to set 'RA' when 'RD' is set unless a server is explicitly set. Integrate contibuted DLZ code into named. Integrate contibuted IDN code from JPNIC. libbind: corresponds to that from BIND 8.4.7. BIND 9.3.0 BIND 9.3.0 has a number of new features over 9.2, including: DNSSEC is now DS based (RFC 3658). See also RFC 3845, doc/draft/draft-ietf-dnsext-dnssec-*. DNSSEC lookaside validation. check-names is now implemented. rrset-order in more complete. IPv4/IPv6 transition support, dual-stack-servers. IXFR deltas can now be generated when loading master files, ixfr-from-differences. It is now possible to specify the size of a journal, max-journal-size. It is now possible to define a named set of master servers to be used in masters clause, masters. The advertised EDNS UDP size can now be set, edns-udp-size. allow-v6-synthesis has been obsoleted. NOTE: * Zones containing MD and MF will now be rejected. * dig, nslookup name. now report "Not Implemented" as NOTIMP rather than NOTIMPL. This will have impact on scripts that are looking for NOTIMPL. libbind: corresponds to that from BIND 8.4.5. BIND 9.2.0 BIND 9.2.0 has a number of new features over 9.1, including: - The size of the cache can now be limited using the "max-cache-size" option. - The server can now automatically convert RFC1886-style recursive lookup requests into RFC2874-style lookups, when enabled using the new option "allow-v6-synthesis". This allows stub resolvers that support AAAA records but not A6 record chains or binary labels to perform lookups in domains that make use of these IPv6 DNS features. - Performance has been improved. - The man pages now use the more portable "man" macros rather than the "mandoc" macros, and are installed by "make install". - The named.conf parser has been completely rewritten. It now supports "include" directives in more places such as inside "view" statements, and it no longer has any reserved words. - The "rndc status" command is now implemented. - rndc can now be configured automatically. - A BIND 8 compatible stub resolver library is now included in lib/bind. - OpenSSL has been removed from the distribution. This means that to use DNSSEC, OpenSSL must be installed and the --with-openssl option must be supplied to configure. This does not apply to the use of TSIG, which does not require OpenSSL. - The source distribution now builds on Windows. See win32utils/readme1.txt and win32utils/win32-build.txt for details. This distribution also includes a new lightweight stub resolver library and associated resolver daemon that fully support forward and reverse lookups of both IPv4 and IPv6 addresses. This library is considered experimental and is not a complete replacement for the BIND 8 resolver library. Applications that use the BIND 8 res_* functions to perform DNS lookups or dynamic updates still need to be linked against the BIND 8 libraries. For DNS lookups, they can also use the new "getrrsetbyname()" API. BIND 9.2 is capable of acting as an authoritative server for DNSSEC secured zones. This functionality is believed to be stable and complete except for lacking support for verifications involving wildcard records in secure zones. When acting as a caching server, BIND 9.2 can be configured to perform DNSSEC secure resolution on behalf of its clients. This part of the DNSSEC implementation is still considered experimental. For detailed information about the state of the DNSSEC implementation, see the file doc/misc/dnssec. There are a few known bugs: On some systems, IPv6 and IPv4 sockets interact in unexpected ways. For details, see doc/misc/ipv6. To reduce the impact of these problems, the server no longer listens for requests on IPv6 addresses by default. If you need to accept DNS queries over IPv6, you must specify "listen-on-v6 { any; };" in the named.conf options statement. FreeBSD prior to 4.2 (and 4.2 if running as non-root) and OpenBSD prior to 2.8 log messages like "fcntl(8, F_SETFL, 4): Inappropriate ioctl for device". This is due to a bug in "/dev/random" and impacts the server's DNSSEC support. OS X 10.1.4 (Darwin 5.4), OS X 10.1.5 (Darwin 5.5) and OS X 10.2 (Darwin 6.0) reports errors like "fcntl(3, F_SETFL, 4): Operation not supported by device". This is due to a bug in "/dev/random" and impacts the server's DNSSEC support. --with-libtool does not work on AIX. A bug in some versions of the Microsoft DNS server can cause zone transfers from a BIND 9 server to a W2K server to fail. For details, see the "Zone Transfers" section in doc/misc/migration. Building BIND 9 currently requires a UNIX system with an ANSI C compiler, basic POSIX support, and a 64 bit integer type. We've had successful builds and tests on the following systems: COMPAQ Tru64 UNIX 5.1B Fedora Core 6 FreeBSD 4.10, 5.2.1, 6.2 HP-UX 11.11 Mac OS X 10.5 NetBSD 3.x and 4.0-beta OpenBSD 3.3 and up Solaris 8, 9, 9 (x86), 10 Ubuntu 7.04, 7.10 Windows XP/2003/2008 NOTE: As of BIND 9.5.1, 9.4.3, and 9.3.6, older versions of Windows, including Windows NT and Windows 2000, are no longer supported. We have recent reports from the user community that a supported version of BIND will build and run on the following systems: AIX 4.3, 5L CentOS 4, 4.5, 5 Darwin 9.0.0d1/ARM Debian 4 Fedora Core 5, 7 FreeBSD 6.1 HP-UX 11.23 PA MacOS X 10.4, 10.5 Red Hat Enterprise Linux 4, 5 SCO OpenServer 5.0.6 Slackware 9, 10 SuSE 9, 10 To build, just ./configure make Do not use a parallel "make". Several environment variables that can be set before running configure will affect compilation: CC The C compiler to use. configure tries to figure out the right one for supported systems. CFLAGS C compiler flags. Defaults to include -g and/or -O2 as supported by the compiler. STD_CINCLUDES System header file directories. Can be used to specify where add-on thread or IPv6 support is, for example. Defaults to empty string. STD_CDEFINES Any additional preprocessor symbols you want defined. Defaults to empty string. Possible settings: Change the default syslog facility of named/lwresd. -DISC_FACILITY=LOG_LOCAL0 Enable DNSSEC signature chasing support in dig. -DDIG_SIGCHASE=1 (sets -DDIG_SIGCHASE_TD=1 and -DDIG_SIGCHASE_BU=1) Disable dropping queries from particular well known ports. -DNS_CLIENT_DROPPORT=0 Sibling glue checking in named-checkzone is enabled by default. To disable the default check set. -DCHECK_SIBLING=0 named-checkzone checks out-of-zone addresses by default. To disable this default set. -DCHECK_LOCAL=0 To create the default pid files in ${localstatedir}/run rather than ${localstatedir}/run/{named,lwresd}/ set. -DNS_RUN_PID_DIR=0 Enable workaround for Solaris kernel bug about /dev/poll -DISC_SOCKET_USE_POLLWATCH=1 The watch timeout is also configurable, e.g., -DISC_SOCKET_POLLWATCH_TIMEOUT=20 LDFLAGS Linker flags. Defaults to empty string. The following need to be set when cross compiling. BUILD_CC The native C compiler. BUILD_CFLAGS (optional) BUILD_CPPFLAGS (optional) Possible Settings: -DNEED_OPTARG=1 (optarg is not declared in ) BUILD_LDFLAGS (optional) BUILD_LIBS (optional) To build shared libraries, specify "--with-libtool" on the configure command line. For the server to support DNSSEC, you need to build it with crypto support. You must have OpenSSL 0.9.5a or newer installed and specify "--with-openssl" on the configure command line. If OpenSSL is installed under a nonstandard prefix, you can tell configure where to look for it using "--with-openssl=/prefix". On some platforms it is necessary to explictly request large file support to handle files bigger than 2GB. This can be done by "--enable-largefile" on the configure command line. On some platforms, BIND 9 can be built with multithreading support, allowing it to take advantage of multiple CPUs. You can specify whether to build a multithreaded BIND 9 by specifying "--enable-threads" or "--disable-threads" on the configure command line. The default is operating system dependent. Support for the "fixed" rrset-order option can be enabled or disabled by specifying "--enable-fixed-rrset" or "--disable-fixed-rrset" on the configure command line. The default is "disabled", to reduce memory footprint. If your operating system has integrated support for IPv6, it will be used automatically. If you have installed KAME IPv6 separately, use "--with-kame[=PATH]" to specify its location. "make install" will install "named" and the various BIND 9 libraries. By default, installation is into /usr/local, but this can be changed with the "--prefix" option when running "configure". You may specify the option "--sysconfdir" to set the directory where configuration files like "named.conf" go by default, and "--localstatedir" to set the default parent directory of "run/named.pid". For backwards compatibility with BIND 8, --sysconfdir defaults to "/etc" and --localstatedir defaults to "/var" if no --prefix option is given. If there is a --prefix option, sysconfdir defaults to "$prefix/etc" and localstatedir defaults to "$prefix/var". To see additional configure options, run "configure --help". Note that the help message does not reflect the BIND 8 compatibility defaults for sysconfdir and localstatedir. If you're planning on making changes to the BIND 9 source, you should also "make depend". If you're using Emacs, you might find "make tags" helpful. If you need to re-run configure please run "make distclean" first. This will ensure that all the option changes take. Building with gcc is not supported, unless gcc is the vendor's usual compiler (e.g. the various BSD systems, Linux). Known compiler issues: * gcc-3.2.1 and gcc-3.1.1 is known to cause problems with solaris-x86. * gcc prior to gcc-3.2.3 ultrasparc generates incorrect code at -02. * gcc-3.3.5 powerpc generates incorrect code at -02. * Irix, MipsPRO 7.4.1m is known to cause problems. A limited test suite can be run with "make test". Many of the tests require you to configure a set of virtual IP addresses on your system, and some require Perl; see bin/tests/system/README for details. SunOS 4 requires "printf" to be installed to make the shared libraries. sh-utils-1.16 provides a "printf" which compiles on SunOS 4. Documentation The BIND 9 Administrator Reference Manual is included with the source distribution in DocBook XML and HTML format, in the doc/arm directory. Some of the programs in the BIND 9 distribution have man pages in their directories. In particular, the command line options of "named" are documented in /bin/named/named.8. There is now also a set of man pages for the lwres library. If you are upgrading from BIND 8, please read the migration notes in doc/misc/migration. If you are upgrading from BIND 4, read doc/misc/migration-4to9. Frequently asked questions and their answers can be found in FAQ. Bug Reports and Mailing Lists Bugs reports should be sent to bind9-bugs@isc.org To join the BIND Users mailing list, send mail to bind-users-request@isc.org archives of which can be found via http://www.isc.org/ops/lists/ If you're planning on making changes to the BIND 9 source code, you might want to join the BIND Workers mailing list. Send mail to bind-workers-request@isc.org bind-9.6-ESV-R6/README.idnkit000644 024064 023255 00000007217 11734112744 015474 0ustar00eachsweng000000 000000 BIND-9 IDN patch Japan Network Information Center (JPNIC) * What is this patch for? This patch adds internationalized domain name (IDN) support to BIND-9. You'll get internationalized version of dig/host/nslookup commands. + internationalized dig/host/nslookup dig/host/nslookup accepts non-ASCII domain names in the local codeset (such as Shift JIS, Big5 or ISO8859-1) determined by the locale information. The domain names are normalized and converted to the encoding on the DNS protocol, and sent to DNS servers. The replies are converted back to the local codeset and displayed. * Compilation & installation 0. Prerequisite You have to build and install idnkit before building this patched version of bind-9. 1. Running configure script Run `configure' in the top directory. See `README' for the configuration options. This patch adds the following 4 options to `configure'. You should at least specify `--with-idn' option to enable IDN support. --with-idn[=IDN_PREFIX] To enable IDN support, you have to specify `--with-idn' option. The argument IDN_PREFIX is the install prefix of idnkit. If IDN_PREFIX is omitted, PREFIX (derived from `--prefix=PREFIX') is assumed. --with-libiconv[=LIBICONV_PREFIX] Specify this option if idnkit you have installed links GNU libiconv. The argument LIBICONV_PREFIX is install prefix of GNU libiconv. If the argument is omitted, PREFIX (derived from `--prefix=PREFIX') is assumed. `--with-libiconv' is shorthand option for GNU libiconv. --with-libiconv=/usr/local This is equivalent to: --with-iconv='-L/usr/local/lib -R/usr/local/lib -liconv' `--with-libiconv' assumes that your C compiler has `-R' option, and that the option adds the specified run-time path to an executable binary. If `-R' option of your compiler has different meaning, or your compiler lacks the option, you should use `--with-iconv' option instead. Binary command without run-time path information might be unexecutable. In that case, you would see an error message like: error in loading shared libraries: libiconv.so.2: cannot open shared object file If both `--with-libiconv' and `--with-iconv' options are specified, `--with-iconv' is prior to `--with-libiconv'. --with-iconv=ICONV_LIBSPEC If your libc doesn't provide iconv(), you need to specify the library containing iconv() with this option. `ICONV_LIBSPEC' is the argument(s) to `cc' or `ld' to link the library, for example, `--with-iconv="-L/usr/local/lib -liconv"'. You don't need to specify the header file directory for "iconv.h" to the compiler, as it isn't included directly by bind-9 with this patch. --with-idnlib=IDN_LIBSPEC With this option, you can explicitly specify the argument(s) to `cc' or `ld' to link the idnkit's library, `libidnkit'. If this option is not specified, `-L${PREFIX}/lib -lidnkit' is assumed, where ${PREFIX} is the installation prefix specified with `--with-idn' option above. You may need to use this option to specify extra arguments, for example, `--with-idnlib="-L/usr/local/lib -R/usr/local/lib -lidnkit"'. Please consult `README' for other configuration options. Note that if you want to specify some extra header file directories, you should use the environment variable STD_CINCLUDES instead of CFLAGS, as described in README. 2. Compilation and installation After running "configure", just do make make install for compiling and installing. * Contact information Please see http//www.nic.ad.jp/en/idn/ for the latest news about idnkit and this patch. Bug reports and comments on this kit should be sent to mdnkit-bugs@nic.ad.jp and idn-cmt@nic.ad.jp, respectively. ; $Id$ bind-9.6-ESV-R6/README.pkcs11000644 024064 023255 00000003540 11734112744 015307 0ustar00eachsweng000000 000000 BIND-9 PKCS#11 support Prerequisite The PKCS#11 support needs a PKCS#11 OpenSSL engine based on the Solaris one, released the 2007-11-21 for OpenSSL 0.9.8g, with a bug fix (call to free) and some improvements, including user friendly PIN management. Compilation "configure --with-pkcs11 ..." PKCS#11 Libraries Tested with Solaris one with a SCA board and with openCryptoki with the software token. OpenSSL Engines With PKCS#11 support the PKCS#11 engine is statically loaded but at its initialization it dynamically loads the PKCS#11 objects. Even the pre commands are therefore unused they are defined with: SO_PATH: define: PKCS11_SO_PATH default: /usr/local/lib/engines/engine_pkcs11.so MODULE_PATH: define: PKCS11_MODULE_PATH default: /usr/lib/libpkcs11.so Without PKCS#11 support, a specific OpenSSL engine can be still used by defining ENGINE_ID at compile time. PKCS#11 tools The contrib/pkcs11-keygen directory contains a set of experimental tools to handle keys stored in a Hardware Security Module at the benefit of BIND. The patch for OpenSSL 0.9.8g is in this directory. Read its README.pkcs11 for the way to use it (these are the original notes so with the original path, etc. Define OPENCRYPTOKI to use it with openCryptoki.) PIN management With the just fixed PKCS#11 OpenSSL engine, the PIN should be entered each time it is required. With the improved engine, the PIN should be entered the first time it is required or can be configured in the OpenSSL configuration file (aka. openssl.cnf) by adding in it: - at the beginning: openssl_conf = openssl_def - at any place these sections: [ openssl_def ] engines = engine_section [ engine_section ] pkcs11 = pkcs11_section [ pkcs11_section ] PIN = put__your__pin__value__here Note Some names here are registered trademarks, at least Solaris is a trademark of Sun Microsystems Inc... bind-9.6-ESV-R6/acconfig.h000644 024064 023255 00000010064 11734112744 015247 0ustar00eachsweng000000 000000 /* * Copyright (C) 2004, 2005, 2007, 2009, 2012 Internet Systems Consortium, Inc.

Synopsis

isc-config.sh [--cflags] [--exec-prefix] [--libs] [--prefix] [--version] [libraries...]

DESCRIPTION

isc-config.sh prints information related to the installed version of ISC BIND, such as the compiler and linker flags required to compile and link programs that use ISC BIND libraries.

The optional libraries are used to report specific details for compiling and linking for the listed libraries. The allowed choices are: isc, isccc, isccfg, dns, lwres, and bind9. Multiple libraries may be listed on the command line. (Some libraries require other libraries, so are implied.)

OPTIONS

--cflags

Prints the compiler command line options required to compile files that use ISC BIND. Use the libraries command line argument(s) to print additional specific flags to pass to the C compiler.

--exec-prefix

Prints the directory prefix used in the ISC BIND installation for architecture dependent files to standard output.

--libs

This is a release of BIND 9.6 for Windows XP and later. Important Kit Installation Information As of release 9.3.0, BINDInstall requires that you install it under a account with restricted privileges. The installer will prompt you for an account name, the default is "named", and a password for that account. It will also check for the existence of that account. If it does not exist is will create it with only the privileges required to run BIND. If the account does exist it will check that it has only the one privilege required: "Log on as a service". If it has too many privileges it will prompt you if you want to continue. With BIND running under an account name it is necessary for all files and directories that BIND uses to have permissions set up for the named account if the files are on an NTFS disk. BIND requires that the account have read and write access to the directory for the pid file, any files that are maintained either for slave zones or for master zones supporting dynamic updates. The account will also need read access to the named.conf and any other file that it needs to read. "NT AUTHORITY\LocalService" is also an acceptable account. This account is built into Windows and no password is required. Appropriate file permissions will also need to be set for "NT AUTHORITY\LocalService" similar to those that would have been required for the "named" account. It is important that on Windows the directory directive is used in the options section to tell BIND where to find the files used in named.conf (default %WINDOWS%\system32\dns\etc\named.conf). e.g. options { directory "C:\WINDOWS\system32\dns\etc"; }; If you have previously installed BIND 8 or BIND 4 on the system that you wish to install this kit, you MUST use the BIND 8 or BIND 4 installer to uninstall the previous kit. For BIND 8.2.x, you can use the BINDInstall that comes with the BIND 8 kit to uninstall it. The BIND 9 installer will NOT uninstall the BIND 8 binaries. That will be fixed in a future release. Unpack the kit into any convenient directory and run the BINDInstall program. This will install the named and associated programs into the correct directories and set up the required registry keys. Messages are logged to the Application log in the EventViewer. Controlling BIND Windows uses the same rndc program as is used on Unix systems. The rndc.conf file must be configured for your system in order to work. You will need to generate a key for this. To do this use the rndc-confgen program. The program will be installed in the same directory as named: dns/bin/. From the DOS prompt, use the command this way: rndc-confgen -a which will create a rndc.key file in the dns/etc directory. This will allow you to run rndc without an explicit rndc.conf file or key and control entry in named.conf file. See section 3.4.1.2 of the ARM for details of this. An rndc.conf can also be generated by running: rndc-confgen > rndc.conf which will create the rndc.conf file in the current directory, but not copy it to the dns/etc directory where it needs to reside. If you create rndc.conf this way you will need to copy the same key statement into named.conf. The additions look like the following: key "rndc-key" { algorithm hmac-md5; secret "xxxxxxxxx=="; }; controls { inet 127.0.0.1 port 953 allow { localhost; } keys { "rndc-key"; }; }; Note that the value of the secret must come from the key generated above for rndc and must be the same key value for both. Details of this may be found in section 3.4.1.2 of the ARM. If you have rndc on a Unix box you can use it to control BIND on the Windows box as well as using the Windows version of rndc to control a BIND 9 daemon on a Unix box. However you must have key statements valid for the servers you wish to control, specifically the IP address and key in both named.conf and rndc.conf. Again see section 3.4.1.2 of the ARM for details. In order to you rndc from a different system it is important to ensure that the clocks are synchronized. The clocks must be kept within 5 minutes of each other or the rndc commands will fail authentication. Use NTP or other time synchronization software to keep your clocks accurate. NTP can be found at http://www.ntp.org/. In addition BIND is installed as a win32 system service, can be started and stopped in the same way as any other service and automatically starts whenever the system is booted. Signals are not supported and are in fact ignored. Note: Unlike most Windows applications, named does not, change its working directory when started as a service. If you wish to use relative files in named.conf you will need to specify a working directory using the directory directive options. Documentation This kit includes Documentation in HTML format. The documentation is not copied during the installation process so you should move it to any convenient location for later reference. Of particular importance is the BIND 9 Administrator's Reference Manual (Bv9ARM*.html) which provides detailed information on BIND 9. In addition, there are HTML pages for each of the BIND 9 applications. DNS Tools The following tools have been built for Windows: dig, nslookup, host, nsupdate, rndc, rndc-confgen, named-checkconf, named-checkzone, dnssec-keygen, dnssec-signzone, dnssec-dsfromkey and dnssec-keyfromlabel. The latter tools are for use with DNSSEC. All tools are installed in the dns/bin directory. IMPORTANT NOTE ON USING THE TOOLS: It is no longer necessary to create a resolv.conf file on Windows as the tools will look in the registry for the required nameserver information. However if you wish to create a resolv.conf file as follows it will use it in preference to the registry nameserver entries. To create a resolv.conf you need to place it in the System32\Drivers\etc directory and it needs to contain a list of nameserver addresses to use to find the nameserver authoritative for the zone. The format of this file is: nameserver 1.2.3.4 nameserver 5.6.7.8 Replace the IP addresses with your real addresses. 127.0.0.1 is a valid address if you are running a nameserver on the localhost. Problems Please report all problems to bind9-bugs@isc.org and not to me. All other questions should go to the bind-users@isc.org mailing list or the comp.protocol.dns.bind news group.

See COPYRIGHT in the source root or http://isc.org/copyright.html for terms. $Id$ BIND 9.4 for Win32 Source Build Instructions. 28-May-2005 Building BIND 9.4 on Windows NT/2000 has the following prerequisites: 1) You need to install Perl for Windows NT/2000. ActiveState (http://www.activestate.com/) is the one most people install and use; 2) OpenSSL (http://www.openssl.org) needs to be downloaded and built on the system on which you are building BIND. 3) If you want to build using Visual C++ 6.0, you'll need some extra files that are to be found in the Platform SDK (which you will need to install), namely: iphlpapi.h iptypes.h ipexport.h iphlpapi.lib You'll also need an updated Iprtrmib.h - using the VC++6.0 one will get you some compilation errors. You can just overwrite the old one if you're not using it for any purposes, and maybe keep a backup of it. You can copy the header files under VC98\INCLUDE and the library file under VC98\LIB. I think you can also put them in a separate directory and add it to the include search list, but I don't know if that can be made persistent. For building on VC++ 7.0 no extra files are required. The instructions assume a Visual C++ 6.0 compiler with Visual Studio and Visual Studio Service Pack 3 or later. It may build and work with earlier versions but it has not been tested. The binaries may be built and run on any of the following platforms: NT 4.0 Workstation (SP3 or later), NT 4.0 Server (SP3 or later), Windows 2000 Professional (SP1 or later), Windows 2000 Server or any kind (SP1 or later), Windows XP, Windows 2003 Server. It will NOT build or run on Windows 95, Windows 98, etc. platforms. Step 1: Download and Build OpenSSL Download and untar the OpenSSL sources from http://www.openssl.org/. if you have place the BIND sources in /BIND9 you should place the OpenSSL sources in /openssl-0.9.7c or the appropriate directory name created when you untarred the openssl tarball. Note: Building OpenSSL also requires that you install Perl as it uses it during its build process. Follow the instructions for NT given in the INSTALL.W32 file to build the kit. This will produce libeay32.lib and libeay32.dll in the out32dll subdirectory. Step 2 Building BIND You must build openssl first. From the command prompt cd to the win32utils under the BIND root. Execute the BuildAll.bat file. This will do the following: 1) copy config.h.win32 to config.h in the root. 2) create the versions.h file in the root. 3) Build the gen application in the lib/dns directory. 4) Run the gen application and build the required lib/dns header files. 5) Create the Build/Release subdirectory under the root of the BIND source tree which will hold the binaries being built. 6) Build the libraries, named, application tools like dig, rndc dnssec tools, installer, checkconf and checkzones programs, BIND 9 Installer. 7) Copies the release notes and the OpenSSL DLL to the BUILD/Release directory. 8) Copies the BIND 9 ARM HTML files and the application HTML files to the Build\Release area. If you wish to use Visual Studio for building, you can just run the BuildSetup.bat file which will create all the necessary files and you can then use the BINDBuild.dsw to open the workspace for all of the libraries and applications. These files reside in the same win32utils directory as this file. The following files are built: libbind9.dll libisc.dll libdns.dll libisccc.dll libisccfg.dll liblwres.dll named.exe bindevt.dll BINDInstall.exe rndc.exe dig.exe host.exe nslookup.exe nsupdate.exe named-checkconf.exe named-checkzone.exe dnssec-keygen.exe dnssec-signzone.exe dnssec-dsfromkey.exe dnssec-keyfromlabel.exe If you are building with VS.NET (aka VC++ V7) you will need additional system DLL's: mfc71.dll msvcr71.dll or mfc70.dll msvcr70.dll depending on your version of the compiler. You should end up with 18-20 binaries in the bind9/Build/Release directory. The Install instructions Readme1st.txt from win32utils and libeay32.dll from the openssl/out32dll/ directory are also copied into the Build area. In addition you should have 22 HTML files and a number of text files. The set of files in the directory bind9/Build/Release form the installation kit which can then be zipped and distributed to any suitable Windows NT 4.0 or Windows 2000 platform. Installation is accomplished by running the BINDInstall program. All DLL's are copied to the system32 area and all applications (including BINDInstall which may be necessary for uninstalling BIND 9) to the dns/bin directory. If BIND 8 has previously been installed on the system it must be uninstalled first by running it's own BINDInstall program. The BIND 9 installer does not yet do this. All bugs found, whether in the process of building the application or running BIND or the tools should be reported to the bind9 bugs email account at bind9-bugs@isc.org.

These are used only when compiling the application from the source code package. If you want to install ATF from a binary package, you do not need to read this document. For the impatient: $ ./configure $ make Gain root privileges # make install Drop root privileges $ make installcheck Or alternatively, install as a regular user into your home directory: $ ./configure --prefix ~/local $ make $ make install $ make installcheck Dependencies ************ To build and use ATF successfully you need: * A standards-compliant C/C++ complier. For example, GNU GCC 2.95 will not work. * A POSIX shell interpreter. * A make(1) utility. If you are building ATF from the code on the repository, you will also need the following tools. The versions listed here are the ones used to build the files bundled in the last formal release, but these are not strictly required. Newer ones will most likely work and, maybe, some slightly older ones: * GNU autoconf 2.68 * GNU automake 1.11.1 * GNU libtool 2.2.6b Regenerating the build system ***************************** If you are building ATF from code extracted from the repository, you must first regenerate the files used by the build system. You will also need to do this if you modify configure.ac, Makefile.am or any of the other build system files. To do this, simply run: $ autoreconf -i -s For formal releases, no extra steps are needed. General build procedure *********************** To build and install the source package, you must follow these steps: 1. Configure the sources to adapt to your operating system. This is done using the 'configure' script located on the sources' top directory, and it is usually invoked without arguments unless you want to change the installation prefix. More details on this procedure are given on a later section. 2. Build the sources to generate the binaries and scripts. Simply run 'make' on the sources' top directory after configuring them. No problems should arise. 3. Install the program by running 'make install'. You may need to become root to issue this step. 4. Issue any manual installation steps that may be required. These are described later in their own section. 5. Check that the installed programs work by running 'make installcheck'. You do not need to be root to do this, even though some checks will not be run otherwise. Configuration flags ******************* The most common, standard flags given to 'configure' are: * --prefix=directory Possible values: Any path Default: /usr/local Specifies where the program (binaries and all associated files) will be installed. * --sysconfdir=directory Possible values: Any path Default: /usr/local/etc Specifies where the installed programs will look for configuration files. '/atf' will be appended to the given path unless ATF_CONFSUBDIR is redefined as explained later on. * --help Shows information about all available flags and exits immediately, without running any configuration tasks. The following environment variables are specific to ATF's 'configure' script: * ATF_BUILD_CC Possible values: empty, a absolute or relative path to a C compiler. Default: the value of CC as detected by the configure script. Specifies the C compiler that ATF will use at run time whenever the build-time-specific checks are used. * ATF_BUILD_CFLAGS Possible values: empty, a list of valid C compiler flags. Default: the value of CFLAGS as detected by the configure script. Specifies the C compiler flags that ATF will use at run time whenever the build-time-specific checks are used. * ATF_BUILD_CPP Possible values: empty, a absolute or relative path to a C/C++ preprocessor. Default: the value of CPP as detected by the configure script. Specifies the C/C++ preprocessor that ATF will use at run time whenever the build-time-specific checks are used. * ATF_BUILD_CPPFLAGS Possible values: empty, a list of valid C/C++ preprocessor flags. Default: the value of CPPFLAGS as detected by the configure script. Specifies the C/C++ preprocessor flags that ATF will use at run time whenever the build-time-specific checks are used. * ATF_BUILD_CXX Possible values: empty, a absolute or relative path to a C++ compiler. Default: the value of CXX as detected by the configure script. Specifies the C++ compiler that ATF will use at run time whenever the build-time-specific checks are used. * ATF_BUILD_CXXFLAGS Possible values: empty, a list of valid C++ compiler flags. Default: the value of CXXFLAGS as detected by the configure script. Specifies the C++ compiler flags that ATF will use at run time whenever the build-time-specific checks are used. * ATF_CONFSUBDIR Possible values: empty, a relative path. Default: atf. Specifies the subdirectory of the configuration directory (given by the --sysconfdir argument) under which ATF will search for its configuration files. * ATF_SHELL Possible values: empty, absolute path to a POSIX shell interpreter. Default: empty. Specifies the POSIX shell interpreter that ATF will use at run time to execute its scripts and the test programs written using the atf-sh library. If empty, the configure script will try to find a suitable interpreter for you. * ATF_WORKDIR Possible values: empty, an absolute path. Default: /tmp or /var/tmp, depending on availability. Specifies the directory that ATF will use to place its temporary files and work directories for test cases. This is just a default and can be overriden at run time. The following flags are specific to ATF's 'configure' script: * --enable-developer Possible values: yes, no Default: Depends on the version number. Stable versions define this to 'no' while all others have it set to 'yes'. Enables several features useful for development, such as the inclusion of debugging symbols in all objects or the enabling of warnings during compilation. * --enable-unstable-shared Possible values: yes, no Default: no. Forces the building of shared libraries in addition to static ones. The build of shared libraries is currently disabled because their ABIs and APIs are unstable and subject to change. This flag is provided for development purposes only and will be removed once the libraries are stable enough. Post-installation steps *********************** After installing ATF, you have to register the DTDs it provides into the system-wide XML catalog. See the comments at the top of the files in ${datadir}/share/xml/atf to see the correct public identifiers. This directory will typically be /usr/local/share/xml/atf or /usr/share/xml/atf. Failure to do so will lead to further errors when processing the XML files generated by atf-report. =========================================================================== vim: filetype=text:textwidth=75:expandtab:shiftwidth=2:softtabstop=2 bind-9.6-ESV-R6/unit/atf-src/Makefile.am000644 024064 023255 00000006642 11734112744 017706 0ustar00eachsweng000000 000000 # # Automated Testing Framework (atf) # # Copyright (c) 2007, 2008, 2009, 2010 The NetBSD Foundation, Inc. # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.

0ustar00eachsweng000000 000000 Major changes between releases Automated Testing Framework =========================================================================== Changes in version 0.12 *********************** Experimental version released on November 7th, 2010. * Added the ATF_REQUIRE_THROW_RE to atf-c++, which is the same as ATF_REQUIRE_THROW but allows checking for the validity of the exception's error message by means of a regular expression. * Added the ATF_REQUIRE_MATCH to atf-c++, which allows checking for a regular expression match in a string. * Changed the default timeout for test cases from 5 minutes to 30 seconds. 30 seconds is long enough for virtually all tests to complete, and 5 minutes is a way too long pause in a test suite where a single test case stalls. * Deprecated the use.fs property. While this seemed like a good idea in the first place to impose more control on what test cases can do, it turns out to be bad. First, use.fs=false prevents bogus test cases from dumping core so after-the-fact debugging is harder. Second, supporting use.fs adds a lot of unnecessary complexity. atf-run will now ignore any value provided to use.fs and will allow test cases to freely access the file system if they wish to. * Added the atf_tc_get_config_var_as_{bool,long}{,_wd} functions to the atf-c library. The 'text' module became private in 0.11 but was being used externally to simplify the parsing of configuration variables. * Made atf-run recognize the 'unprivileged-user' configuration variable and automatically drop root privileges when a test case sets require.user=unprivileged. Note that this is, by no means, done for security purposes; this is just for user convenience; tests should, in general, not be blindly run as root in the first place. Changes in version 0.11 *********************** Experimental version released on October 20th, 2010. * The ATF_CHECK* macros in atf-c++ were renamed to ATF_REQUIRE* to match their counterparts in atf-c. * Clearly separated the modules in atf-c that are supposed to be public from those that are implementation details. The header files for the internal modules are not installed any more. * Made the atf-check tool private. It is only required by atf-sh and being public has the danger of causing confusion. Also, making it private simplifies the public API of atf. * Changed atf-sh to enable per-command error checking (set -e) by default. This catches many cases in which a test case is broken but it is not reported as such because execution continues. * Fixed the XSTL and CSS stylesheets to support expected failures. Changes in version 0.10 *********************** Experimental version released on July 2nd, 2010. Miscellaneous features * Added expected failures support to test cases and atf-run. These include, for example, expected clean exits, expected reception of fatal signals, expected timeouts and expected errors in condition checks. These statuses can be used to denote test cases that are known to fail due to a bug in the code they are testing. atf-report reports these tests separately but they do not count towards the failed test cases amount. * Added the ATF_CHECK_ERRNO and ATF_REQUIRE_ERRNO to the C library to allow easy checking of call failures that update errno. * Added the has.cleanup meta-data property to test caes that specifies whether the test case has a cleanup routine or not; its value is automatically set. This property is read by atf-run to know if it has to run the cleanup routine; skipping this run for every test case significantly speeds up the run time of test suites. * Reversed the order of the ATF_CHECK_THROW macro in the C++ binding to take the expected exception as the first argument and the statement to execute as the second argument. Changes in atf-check * Changed atf-check to support negating the status and output checks by prefixing them with not- and added support to specify multiple checkers for stdout and stderr, not only one. * Added the match output checker to atf-check to look for regular expressions in the stdout and stderr of commands. * Modified the exit checks in atf-check to support checking for the reception of signals. Code simplifications and cleanups * Removed usage messages from test programs to simplify the implementation of every binding by a significant amount. They just now refer the user to the appropriate manual page and do not attempt to wrap lines on terminal boundaries. Test programs are not supposed to be run by users directly so this minor interface regression is not important. * Removed the atf-format internal utility, which is unused after the change documented above. * Removed the atf-cleanup internal utility. It has been unused since the test case isolation was moved to atf-run in 0.8 * Splitted the Makefile.am into smaller files for easier maintenance and dropped the use of M4. Only affects users building from the repository sources. * Intermixed tests with the source files in the source tree to provide them more visibility and easier access. The tests directory is gone from the source tree and tests are now suffixed by _test, not prefixed by t_. * Simplifications to the atf-c library: removed the io, tcr and ui modules as they had become unnecessary after all simplifications introduced since the 0.8 release. * Removed the application/X-atf-tcr format introduced in 0.8 release. Tests now print a much simplified format that is easy to parse and nicer to read by end users. As a side effect, the default for test cases is now to print their results to stdout unless otherwise stated by providing the -r flag. * Removed XML distribution documents and replaced them with plain-text documents. They provided little value and introduced a lot of complexity to the build system. * Simplified the output of atf-version by not attempting to print a revision number when building form a distfile. Makes the build system easier to maintain. Changes in version 0.9 ********************** Experimental version released on June 3rd, 2010. * Added atf-sh, an interpreter to process test programs written using the shell API. This is not really a shell interpreter by itself though: it is just a wrapper around the system shell that eases the loading of the necessary ATF libraries. * Removed atf-compile in favour of atf-sh. * Added the use.fs metadata property to test case, which is used to specify which test cases require file system access. This is to highlight dependencies on external resources more clearly and to speed up the execution of test suites by skipping the creation of many unnecessary work directories. * Fixed test programs to get a sane default value for their source directory. This means that it should not be necessary any more to pass -s when running test programs that do not live in the current directory. * Defining test case headers became optional. This is trivial to achieve in shell-based tests but a bit ugly in C and C++. In C, use the new ATF_TC_WITHOUT_HEAD macro to define the test case, and in C++ use ATF_TEST_CASE_WITHOUT_HEAD. Changes in version 0.8 ********************** Experimental version released on May 7th, 2010. * Test programs no longer run several test cases in a row. The execution of a test program now requires a test case name, and that single test case is executed. To execute several test cases, use the atf-run utility as usual. * Test programs no longer fork a subprocess to isolate the execution of test cases. They run the test case code in-process, and a crash of the test case will result in a crash of the test program. This is to ease debugging of faulty test cases. * Test programs no longer isolate their test cases. This means that they will not create temporary directories nor sanitize the environment any more. Yes: running a test case that depends on system state by hand will most likely yield different results depending on where (machine, directory, user environment, etc.) it is run. Isolation has been moved to atf-run. * Test programs no longer print a cryptic format (application/X-atf-tcs) on a special file channel. They can now print whatever they want on the screen. Because test programs can now only run one test case every time, providing controlled output is not necessary any more. * Test programs no longer write their status into a special file descriptor. Instead, they create a file with the results, which is later parsed by atf-run. This changes the semantics of the -r flag. * atf-run has been adjusted to perform the test case isolation. As a result, there is now a single canonical place that implements the isolation of test caes. In previous releases, the three language bindings (C, C++ and shell) had to be kept in sync with each other (read: not a nice thing to do at all). As a side effect of this change, writing bindings for other languages will be much, much easier from now on. * atf-run forks test programs on a test case basis, instead of on a test program basis as it did before. This is to provide the test case isolation that was before implemented by the test programs themselves. * Removed the atf-exec tool. This was used to implement test case isolation in atf-sh, but it is now unnecessary. * It is now optional to define the descr meta-data property. It has been proven to be mostly useless, because test cases often carry a descriptive name of their own. Changes in version 0.7 ********************** Experimental version released on December 22nd, 2009. * Added build-time checks to atf-c and atf-c++. A binding for atf-sh will come later. * Migrated all build-time checks for header files to proper ATF tests. This demonstrates the use of the new feature described above. * Added an internal API for child process management. * Converted all plain-text distribution documents to a Docbook canonical version, and include pre-generated plain text and HTML copies in the distribution file. * Simplified the contents of the Makefile.am by regenerating it from a canonical Makefile.am.m4 source. As a side-effect, some dependency specifications were fixed. * Migrated all checks from the check target to installcheck, as these require ATF to be installed. * Fixed sign comparison mismatches triggered by the now-enabled -Wsign-compare. * Fixed many memory and object leaks. Changes in version 0.6 ********************** Experimental version released on January 18th, 2009. * Make atf-exec be able to kill its child process after a certain period of time; this is controlled through the new -t option. * Change atf-sh to use atf-exec's -t option to control the test case's timeouts, instead of doing it internally. Same behavior as before, but noticeably faster. * atf-exec's -g option and atf-killpg are gone due to the previous change. * Added the atf-check(1) tool, a program that executes a given command and checks its exit code against a known value and allows the management of stdout and stderr in multiple ways. This replaces the previous atf_check function in the atf-sh library and exposes this functionality to both atf-c and atf-c++. * Added the ATF_REQUIRE family of macros to the C interface. These help in checking for fatal test conditions. The old ATF_CHECK macros now perform non-fatal checks only. I.e. by using ATF_CHECK, the test case can now continue its execution and the failures will not be reported until the end of the whole run. * Extended the amount of ATF_CHECK_* C macros with new ones to provide more features to the developer. These also have their corresponding counterparts in the ATF_REQUIRE_* family. The new macros (listing the suffixes only) are: _EQ (replaces _EQUAL), _EQ_MSG, _STREQ and _STREQ_MSG. Changes in version 0.5 ********************** Experimental version released on May 1st, 2008. * Clauses 3 and 4 of the BSD license used by the project were dropped. All the code is now under a 2-clause BSD license compatible with the GNU General Public License (GPL). * Added a C-only binding so that binary test programs do not need to be tied to C++ at all. This binding is now known as the atf-c library. * Renamed the C++ binding to atf-c++ for consistency with the new atf-c. * Renamed the POSIX shell binding to atf-sh for consistency with the new atf-c and atf-c++. * Added a -w flag to test programs through which it is possible to specify the work directory to be used. This was possible in prior releases by defining the workdir configuration variable (-v workdir=...), but was a conceptually incorrect mechanism. * Test programs now preserve the execution order of test cases when they are given in the command line. Even those mentioned more than once are executed multiple times to comply with the user's requests. Changes in version 0.4 ********************** Experimental version released on February 4th, 2008. * Added two new manual pages, atf-c++-api and atf-sh-api, describing the C++ and POSIX shell interfaces used to write test programs. * Added a pkg-config file, useful to get the flags to build against the C++ library or to easily detect the presence of ATF. * Added a way for test cases to require a specific architecture and/or machine type through the new 'require.arch' and 'require.machine' meta-data properties, respectively. * Added the 'timeout' property to test cases, useful to set an upper-bound limit for the test's run time and thus prevent global test program stalls due to the test case's misbehavior. * Added the atf-exec(1) internal utility, used to execute a command after changing the process group it belongs to. * Added the atf-killpg(1) internal utility, used to kill process groups. * Multiple portability fixes. Of special interest, full support for SunOS (Solaris Express Developer Edition 2007/09) using the Sun Studio 12 C++ compiler. * Fixed a serious bug that prevented atf-run(1) from working at all under Fedora 8 x86_64. Due to the nature of the bug, other platforms were likely affected too. Changes in version 0.3 ********************** Experimental version released on November 11th, 2007. * Added XML output support to atf-report. This is accompanied by a DTD for the format's structure and sample XSLT/CSS files to post-process this output and convert it to a plain HTML report. * Changed atf-run to add system information to the report it generates. This is currently used by atf-report's XML output only, and is later printed in the HTML reports in a nice and useful summary table. The user and system administrator are allowed to tune this feature by means of hooks. * Removed the test cases' 'isolated' property. This was intended to avoid touching the file system at all when running the related test case, but this has not been true for a long while: some control files are unconditionally required for several purposes, and we cannot easily get rid of them. This way we remove several critical and delicate pieces of code. * Improved atf-report's CSV output format to include information about test programs too. * Fixed the tests that used atf-compile to not require this tool as a helper. Avoids systems without build-time utilities to skip many tests that could otherwise be run. (E.g. NetBSD without the comp.tgz set installed.) * Many general cleanups: Fixed many pieces of code marked as ugly and/or incomplete. Changes in version 0.2 ********************** Experimental version released on September 20th, 2007. * Test cases now get a known umask on entry. * atf-run now detects many unexpected failures caused by test programs and reports them as bogus tests. atf-report is able to handle these new errors and nicely reports them to the user. * All the data formats read and written by the tools have been documented and cleaned up. These include those grammars that define how the different components communicate with each other as well as the format of files written by the developers and users: the Atffiles and the configuration files. * Added the atf-version tool, a utility that displays information about the currently installed version of ATF. * Test cases can now define an optional cleanup routine to undo their actions regardless of their exit status. * atf-report now summarizes the list of failed (bogus) test programs when using the ticker output format. * Test programs now capture some termination signals and clean up any temporary files before exiting the program. * Multiple bug fixes and improvements all around. Changes in version 0.1 ********************** Experimental version released on August 20th, 2007. * First public version. This was released coinciding with the end of the Google Summer of Code 2007 program. =========================================================================== vim: filetype=text:textwidth=75:expandtab:shiftwidth=2:softtabstop=2 bind-9.6-ESV-R6/unit/atf-src/README000644 024064 023255 00000003017 11734112744 016523 0ustar00eachsweng000000 000000 Introductory information Automated Testing Framework =========================================================================== Introduction ************ The Automated Testing Framework (ATF) is a collection of libraries and utilities designed to ease unattended application testing in the hands of developers and end users of a specific piece of software. As regards developers, ATF provides the necessary means to easily create test suites composed of multiple test programs, which in turn are a collection of test cases. It also attempts to simplify the debugging of problems when these test cases detect an error by providing as much information as possible about the failure. As regards users, it simplifies the process of running the test suites and, in special, encourages end users to run them often: they do not need to have source trees around nor any other development tools installed to be able to certify that a given piece of software works on their machine as advertised.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

These formats affect configuration files, control files and any data that is externalized or internalized by the tools. .Pp Data files are always organized as follows: .Bd -literal -offset indent Header1: Value1 \\ ... | head HeaderN: ValueN / mandatory blank line Free-form text contents \\ ... | body ... / .Ed .Pp A file must always contain a .Sq Content-Type header and must always separate that header from the body with a blank line, even if the body is empty. .Pp The .Sq Content-Type is always of the form: .Bd -literal -offset indent Content-Type: application/X-atf-; version="" .Ed .Pp where .Sq subtype indicates the specific file format and .Sq version its format version. This header must be the first one of the file. .Pp The main purpose of the .Sq Content-Type header, aside from determining the format used in the file, is to allow future changes to a given format. Whenever an incompatible change is made, the version is bumped by one. By keeping the header in the first line, future versions may even remove the need for such a header -- e.g. if some format was replaced by XML files, which have their own mandatory header. .Pp The rest of this document details the different format types. .Ss Format: application/X-atf-atffile, version: 1 Atffiles are logically divided into three sections: .Bl -bullet .It Test programs: the list of test programs that define the test suite described by the Atffile. .It Meta-data properties: these define some constant values applicable to all the test programs defined in the file. In some sense they define the properties that describe the test suite. .It Configuration variables: defaults for configuration variables that can be overridden through configuration files or the command line. .El .Pp The grammar for Atffiles is the following: .Bd -literal -offset indent DATA ::= ( ( CONF | PROP | TP )? COMMENT? NEWLINE )* EOF CONF ::= 'conf:' WORD EQUAL STRING PROP ::= 'prop:' WORD EQUAL STRING TP ::= TPFILE | TPGLOB TPFILE ::= 'tp: ' STRING TPGLOB ::= 'tp-glob: ' STRING STRING ::= WORD | '"' WORD* '"' .Ed .Pp The meaning of the constructions above is: .Bl -tag -width TPGLOBXX .It CONF Definition of a configuration variable. .It PROP Definition of a meta-data property. .It TPFILE Addition of a test program into the test suite. The string is taken literally as the program's name, and this program must exist. .It TPGLOB Addition of multiple test programs into the test suite. The string is taken as a glob pattern, which may have or not have any matches in the current directory. .El .Pp An example: .Bd -literal -offset indent prop: test-suite = utilities conf: unprivileged-user = nobody tp: t_cp tp: t_mv tp: t_df tp-glob: t_dir_* .Ed .Ss Format: application/X-atf-config, version: 1 Configuration files are very simple: they only contain a list of variable name/variable value pairs. Their grammar is: .Bd -literal -offset indent DATA ::= ( VAR? COMMENT? NEWLINE )* EOF VAR ::= WORD EQUAL STRING COMMENT ::= HASH WORD* STRING ::= WORD | '"' WORD* '"' .Ed .Pp An example: .Bd -literal -offset indent # This is the system-wide configuration file for ATF. # The above and this line are comments placed on their own line. var1 = this is a variable value var2 = this is another one # Optional comment at the end. .Ed .Ss Format: application/X-atf-tps, version: 2 The .Sq application/X-atf-tps format multiplexes the standard output, standard error and results output streams from multiple test programs into a single data file. This format is used by .Xr atf-run 1 to report the execution of several test programs and is later parsed by .Xr atf-report 1 to inform the user of this process. It has the following grammar: .Bd -literal -offset indent DATA ::= INFO* TPS-COUNT TP-STANZA* INFO* EOF INFO ::= 'info' COLON STRING COMMA STRING NEWLINE TPS-COUNT ::= 'tps-count' COLON POSITIVE-NUMBER NEWLINE TP-STANZA ::= TP-START TC-STANZA* TC-END TP-START ::= 'tp-start' COLON STRING COMMA POSITIVE-NUMBER NEWLINE TP-END ::= 'tc-end' COLON STRING (COMMA STRING)? TC-STANZA ::= TC-START (TC-SO | TC-SE)* TC-END TC-START ::= 'tc-start' COLON STRING NEWLINE TC-SO ::= 'tc-so' COLON STRING NEWLINE TC-SE ::= 'tc-se' COLON STRING NEWLINE TC-END ::= 'tc-end' COLON STRING COMMA TCR NEWLINE TCR ::= 'passed' | ('failed' | 'skipped') COMMA STRING .Ed .Pp The meaning of the constructions above is: .Bl -tag -width TPSXCOUNTXX .It TPS-COUNT Indicates the number of test programs that will be executed. There will be this exact amount of .Sq TP-STANZA constructions following it. .It TP-START Indicates the beginning of a test program. This includes the program's name and the amount of test cases that will follow. .It TP-END Indicates the completion of a test program. This is followed by the program's name and, if the program ended prematurely, an error message indicating the reason of its failure. A successful execution of a test program (regardless of the status of its test cases) must not be accompanied by any reason. .It TC-START Indicates the beginning of a test case. This is accompanied by the test case's name. .It TC-SO Contains a text line sent to the standard output stream during the execution of the test case. Leading and trailing space is preserved. .It TC-SE Contains a text line sent to the standard error stream during the execution of the test case. Leading and trailing space is preserved. .It TC-END Indicates the completion of a test case. This is accompanied by the test case's name, its result and the reason associated with this result (if applicable). .El .Pp An example: .Bd -literal -offset indent tps-count: 2 tp-start: calculator, 2 tc-start: add tc-end: add, passed tc-start: subtract tc-so: 3-2 expected to return 1 but got 0 tc-end: subtract, failed, Calculated an unexpected value tp-end: calculator tp-start: files, 1 tc-start: copy tc-se: could not find the cp(1) utility tc-end: copy, skipped tp-end: files .Ed .Sh SEE ALSO .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/doc/atf-test-case.4000644 024064 023255 00000023451 11734112744 021141 0ustar00eachsweng000000 000000 .\" .\" Automated Testing Framework (atf) .\" .\" Copyright (c) 2007, 2008, 2010 The NetBSD Foundation, Inc. .\" All rights reserved. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.

This feature is typically self-contained enough, either in the amount of code that implements it or in the general idea that describes it, to warrant its independent testing. Given this, test cases are very fine-grained, but they attempt to group similar smaller tests which are semantically related. .Pp A test case is defined by three components regardless of the language it is implemented in: a header, a body and a cleanup routine. The .Em header is, basically, a declarative piece of code that defines several properties to describe what the test case does and how it behaves. In other words: it defines the test case's .Em meta-data , further described in the .Sx Meta-data section. The .Em body is the test case itself. It executes all actions needed to reproduce the test, and checks for failures. This body is only executed if the abstract conditions specified by the header are met. The .Em cleanup routine routine is a piece of code always executed after the body, regardless of the exit status of the test case. It can be used to undo side-effects of the test case. Note that almost all side-effects of a test case are automatically cleaned up by the library; this is explained in more detail in the rest of this document. .Pp It is extremely important to keep the separation between a test case's header and body well-defined, because the header is .Em always parsed, whereas the body is only executed when the conditions defined in the header are met and when the user specifies that test case. .Pp At last, test cases are always contained into test programs. The test programs act as a front-end to them, providing a consistent interface to the user and several APIs to ease their implementation. .Ss Results Upon termination, a test case reports a status and, optionally, a textual reason describing why the test reported such status. The caller must ensure that the test case really performed the task that its status describes, as the test program may be bogus and therefore providing a misleading result (e.g. providing a result that indicates success but the error code of the program says otherwise). .Pp The possible exit status of a test case are one of the following: .Bl -tag -width expectedXfailureXX .It expected_death The test case expects to terminate abruptly. .It expected_exit The test case expects to exit cleanly. .It expected_failure The test case expects to exit with a controller fatal/non-fatal failure. If this happens, the test program exits with a success error code. .It expected_signal The test case expects to receive a signal that makes it terminate. .It expected_timeout The test case expects to execute for longer than its timeout. .It passed The test case was executed successfully. The test program exits with a success error code. .It skipped The test case could not be executed because some preconditions were not met. This is not a failure because it can typically be resolved by adjusting the system to meet the necessary conditions. This is always accompanied by a .Em reason , a message describing why the test was skipped. The test program exits with a success error code. .It failed An error appeared during the execution of the test case. This is always accompanied by a .Em reason , a message describing why the test failed. The test program exits with a failure error code. .El .Pp The usefulness of the .Sq expected_* results comes when writing test cases that verify known failures caused, in general, due to programming errors (aka bugs). Whenever the faulty condition that the expectation is trying to convery is fixed, then the test case will be reported as .Sq failed and the developer will have to adjust it to match its new condition. .Pp It is important to note that all .Sq expected_* results are only provided as a .Em hint to the caller; the caller must verify that the test case did actually terminate as the expected condition says. .Ss Input/output Test cases are free to print whatever they want to their .Xr stdout 4 and .Xr stderr 4 file descriptors. They are, in fact, encouraged to print status information as they execute to keep the user informed of their actions. This is specially important for long test cases. .Pp Test cases will log their results to an auxiliary file, which is then collected by the test program they are contained in. The developer need not care about this as long as he uses the correct APIs to implement the test cases. .Ss Meta-data The following list describes all meta-data properties interpreted internally by ATF. You are free to define new properties in your test cases and use them as you wish, but non-standard properties must be prefixed by .Sq X- . .Bl -tag -width requireXmachineXX .It descr Type: textual. Required. .Pp A brief textual description of the test case's purpose. Will be shown to the user in reports. Also good for documentation purposes. .It has.cleanup Type: boolean. Optional. .Pp If set to true, specifies that the test case has a cleanup routine that has to be executed by .Xr atf-run 1 during the cleanup phase of the execution. This property is automatically set by the framework when defining a test case with a cleanup routine, so it should never be set by hand. .It ident Type: textual. Required. .Pp The test case's identifier. Must be unique inside the test program and should be short but descriptive. .It require.arch Type textual. Optional. .Pp A whitespace separated list of architectures that the test case can be run under without causing errors due to an architecture mismatch. .It require.config Type: textual. Optional. .Pp A whitespace separated list of configuration variables that must be defined to execute the test case. If any of the required variables is not defined, the test case is .Em skipped . .It require.machine Type textual. Optional. .Pp A whitespace separated list of machine types that the test case can be run under without causing errors due to a machine type mismatch. .It require.progs Type: textual. Optional. .Pp A whitespace separated list of programs that must be present to execute the test case. These can be given as plain names, in which case they are looked in the user's .Ev PATH , or as absolute paths. If any of the required programs is not found, the test case is .Em skipped . .It require.user Type: textual. Optional. .Pp The required privileges to execute the test case. Can be one of .Sq root or .Sq unprivileged . If the requested privileges do not match the current user, the test case is .Em skipped . .Pp .Em NOTE : In the future, it is expected that the test case will attempt to gain the necessary privileges on its own before failing. At the very least, lowering the privileges from the super-user to an unprivileged user will be supported. .It timeout Type: integral. Optional; defaults to .Sq 30 . .Pp Specifies the maximum amount of time the test case can run. This is particularly useful because some tests can stall either because they are incorrectly coded or because they trigger an anomalous behavior of the program. It is not acceptable for these tests to stall the whole execution of the test program. .Pp Can optionally be set to zero, in which case the test case has no run-time limit. This is discouraged. .El .Ss Environment Every time a test case is executed, several environment variables are cleared or reseted to sane values to ensure they do not make the test fail due to unexpected conditions. These variables are: .Bl -tag -width LCXMESSAGESXX .It Ev HOME Set to the work directory's path. .It Ev LANG Undefined. .It Ev LC_ALL Undefined. .It Ev LC_COLLATE Undefined. .It Ev LC_CTYPE Undefined. .It Ev LC_MESSAGES Undefined. .It Ev LC_MONETARY Undefined. .It Ev LC_NUMERIC Undefined. .It Ev LC_TIME Undefined. .It Ev TZ Undefined. .El .Ss Work directories The test program always creates a temporary directory and switches to it before running the test case's body. This way the test case is free to modify its current directory as it wishes, and the test program will be able to clean it up later on in a safe way, removing any traces of its execution from the system. .Ss File creation mode mask (umask) Test cases are always executed with a file creation mode mask (umask) of .Sq 0022 . The test case's code is free to change this during execution. .Sh SEE ALSO .Xr atf-test-program 1 , .Xr atf-formats 5 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/doc/atf-test-program.1000644 024064 023255 00000007314 11734112744 021672 0ustar00eachsweng000000 000000 .\" .\" Automated Testing Framework (atf) .\" .\" Copyright (c) 2007, 2008, 2010 The NetBSD Foundation, Inc. .\" All rights reserved. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.

Fl v Ar varN=valueN .Ar test_case .Nm .Fl l .Sh DESCRIPTION Test programs written using the ATF libraries all share a common user interface, which is what this manual page describes. .Pp In the first synopsis form, the test program will execute the provided test case and print its results to the standard output, unless otherwise stated by the .Fl r flag. Optionally, the test case name can be suffixed by .Sq :cleanup , in which case the cleanup routine of the test case will be executed instead of the test case body; see .Xr atf-test-case 4 . Note that the test case is .Em executed without isolation , so it can and probably will create and modify files in the current directory. To execute test cases in a controller manner, refer to .Xr atf-run 1 , which is the preferred way to run test cases. You should only execute test cases by hand for debugging purposes. .Pp In the second synopsis form, the test program will list all available test cases alongside their meta-data properties in a format that is machine parseable. This list is processed by .Xr atf-run 1 to know how to execute the test cases of a given test program. .Pp The following options are available: .Bl -tag -width XvXvarXvalueXX .It Fl l Lists available test cases alongside a brief description for each of them. .It Fl r Ar resfile Specifies the file that will receive the test case result. If not specified, the test case prints its results to stdout. If the result of a test case needs to be parsed by another program, you must use this option to redirect the result to a file and then read the resulting file from the other program. Note: .Em do not try to process the stdout of the test case because your program may break in the future. .It Fl s Ar srcdir The path to the directory where the test program is located. This is needed in all cases, except when the test program is being executed from the current directory. The test program will use this path to locate any helper data files or utilities. .It Fl v Ar var=value Sets the configuration variable .Ar var to the value .Ar value . .El .Sh SEE ALSO .Xr atf-run 1 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/doc/atf.7.in000644 024064 023255 00000013174 11734112744 017664 0ustar00eachsweng000000 000000 .\" .\" Automated Testing Framework (atf) .\" .\" Copyright (c) 2007, 2008, 2009, 2010 The NetBSD Foundation, Inc. .\" All rights reserved. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.

It also attempts to simplify the debugging of problems when these test cases detect an error by providing as much information as possible about the failure. .Pp As regards users, it simplifies the process of running the test suites and, in special, encourages end users to run them often: they do not need to have source trees around nor any other development tools installed to be able to certify that a given piece of software works on their machine as advertised. .Pp If your operating systems distributes .Nm , it is possible that it provides an introductory .Xr tests 7 manual page. You are encouraged to read it now. .Ss License .Nm is distributed under the terms of the TNF License, a 2-clause BSD license. For more details please see: .Bd -literal -offset indent .Pa __DOCDIR__/COPYING .Ed .Ss Components .Nm is a highly modular piece of software. It provides a couple of libraries to ease the implementation of test programs: one for the C and C++ languages and another one for shell scripts. It also includes multiple small utilities that follow the principle of doing a single thing but doing it right. This section outlines which these components are. .Pp Public utilities: .Bl -tag -width atfXtestXprogramXXXXX .It Xr atf-check 1 Executes a command and checks that its exit code, its standard output and its standard error output match pre-specified expected values. .It Xr atf-config 1 Queries static configuration information. .It Xr atf-report 1 Converts the output of .Nm atf-run to user-friendly and/or machine-parseable reports. .It Xr atf-run 1 Automates the execution of a series of test programs and collects their results in a unified report. .It Xr atf-sh 1 Shell interpreter for shell-based test programs. .El .Pp Programming interfaces: .Bl -tag -width atfXtestXprogramXXXXX .It Xr atf-c-api 3 C programming interface for test programs. .It Xr atf-c++-api 3 C++ programming interface for test programs. .It Xr atf-sh-api 3 POSIX shell programming interface for test programs. .El .Pp Other: .Bl -tag -width atfXtestXprogramXXXXX .It Xr atf-formats 5 Description of the machine-parseable data formats used by the tools. .It Xr atf-test-case 4 Generic description of test cases, independent of the language they are implemented in. .It Xr atf-test-program 1 Common interface provided by the test programs written using the .Nm libraries. .El .Ss Recommended reading order For end users wishing to run tests: .Bl -enum -compact .It .Xr tests 7 (only if provided by your operating system). .It .Xr atf-test-program 1 .It .Xr atf-run 1 .It .Xr atf-report 1 .It .Xr atf-config 1 .El .Pp For developers wanting to write their own tests: .Bl -enum -compact .It Everything recommended to users. .It .Xr atf-test-case 4 .It .Xr atf-c-api 3 .It .Xr atf-c++-api 3 .It .Xr atf-sh-api 3 .It .Xr atf-sh 1 .It .Xr atf-check 1 .El .Pp For those interested in .Nm internals: .Bl -enum -compact .It Everything recommended to users. .It Everything recommended to developers. .It .Xr atf-formats 5 .El .Sh SEE ALSO .Xr tests 7 .Sh HISTORY .Nm started as a Google Summer of Code 2007 project mentored by The NetBSD Foundation. Its original goal was to provide a testing framework for The NetBSD Operating System, but it grew as an independent project because the framework itself did not need to be tied to a specific operating system. .Pp For more details on this subject, please see: .Bd -literal -offset indent .Pa __DOCDIR__/NEWS .Pa __DOCDIR__/ROADMAP .Ed .Sh AUTHORS For more details on the people that made .Nm possible, please see: .Bd -literal -offset indent .Pa __DOCDIR__/AUTHORS .Ed bind-9.6-ESV-R6/unit/atf-src/bootstrap/Makefile.am.inc000644 024064 023255 00000011377 11734112744 022474 0ustar00eachsweng000000 000000 # # Automated Testing Framework (atf) # # Copyright (c) 2007, 2008, 2009, 2010 The NetBSD Foundation, Inc. # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.

By default it will act as if it was run with .Fl s .Ar exit:0 .Fl o .Ar empty .Fl e .Ar empty . Multiple checks for the same output channel are allowed and, if specified, their results will be combined as a logical and (meaning that the output must match all the provided checks). .Pp In the second synopsis form, .Nm will print information about all supported options and their purpose. .Pp The following options are available: .Bl -tag -width XqualXvalueXX .It Fl h Shows a short summary of all available options and their purpose. .It Fl s Ar qual:value Analyzes termination status. Must be one of: .Bl -tag -width signal: -compact .It Ar exit: checks that the program exited cleanly and that its exit status is equal to .Va value . The exit code can be omitted altogether, in which case any clean exit is accepted. .It Ar ignore ignores the exit check. .It Ar signal: checks that the program exited due to a signal and that the signal that terminated it is .Va value . The signal can be specified both as a number or as a name, or it can also be omitted altogether, in which case any signal is accepted. .El .Pp Most of these checkers can be prefixed by the .Sq not- string, which effectively reverses the check. .It Fl o Ar action:arg Analyzes standard output. Must be one of: .Bl -tag -width inline: -compact .It Ar empty checks that stdout is empty .It Ar ignore ignores stdout .It Ar file: compares stdout with given file .It Ar inline: compares stdout with inline value .It Ar match: looks for a regular expression in stdout .It Ar save: saves stdout to given file .El .Pp Most of these checkers can be prefixed by the .Sq not- string, which effectively reverses the check. .It Fl e Ar action:arg Analyzes standard error (syntax identical to above) .It Fl x Executes .Ar command as a shell command line, executing it with the system shell defined by .Va ATF_SHELL in .Xr atf-config 1 . You should avoid using this flag if at all possible to prevent shell quoting issues. .El .Sh EXIT STATUS .Nm exits 0 on success, and other (unspecified) value on failure. .Sh EXAMPLES .Bd -literal -offset indent # Exit code 0, nothing on stdout/stderr atf-check 'true' # Typical usage if failure is expected atf-check -s not-exit:0 'false' # Checking stdout/stderr echo foobar >expout atf-check -o file:expout -e inline:"xx\etyy\en" \e 'echo foobar ; printf "xx\etyy\en" >&2' # Checking for a crash atf-check -s signal:sigsegv my_program # Combined checks atf-check -o match:foo -o not-match:bar echo foo baz .Ed .Sh SEE ALSO .Xr atf-config 1 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-sh/atf-check.cpp000644 024064 023255 00000055051 11734112744 021363 0ustar00eachsweng000000 000000 // // Automated Testing Framework (atf) // // Copyright (c) 2008, 2009, 2010 The NetBSD Foundation, Inc. // All rights reserved. // // Redistribution and use in source and binary forms, with or without // modification, are permitted provided that the following conditions // are met: // 1.

These are extremely helpful given that they are trivial to write due to the language simplicity and the great deal of available external tools, so they are often ideal to test other applications at the user level. .Pp Test programs written using this library must be run using the .Xr atf-sh 1 interpreter by putting the following on their very first line: .Bd -literal -offset indent #! /usr/bin/env atf-sh .Ed .Pp Shell-based test programs always follow this template: .Bd -literal -offset indent atf_test_case tc1 tc1_head() { ... first test case's header ... } tc1_body() { ... first test case's body ... } atf_test_case tc2 cleanup tc2_head() { ... second test case's header ... } tc2_body() { ... second test case's body ... } tc2_cleanup() { ... second test case's cleanup ... } .Ns ... additional test cases ... atf_init_test_cases() { atf_add_test_case tc1 atf_add_test_case tc2 ... add additional test cases ... } .Ed .Ss Definition of test cases Test cases have an identifier and are composed of three different parts: the header, the body and an optional cleanup routine, all of which are described in .Xr atf-test-case 4 . To define test cases, one can use the .Fn atf_test_case function, which takes a first parameter specifiying the test case's name and instructs the library to set things up to accept it as a valid test case. The second parameter is optional and, if provided, must be .Sq cleanup ; providing this parameter allows defining a cleanup routine for the test case. It is important to note that this function .Em does not set the test case up for execution when the program is run. In order to do so, a later registration is needed through the .Fn atf_add_test_case function detailed in .Sx Program initialization . .Pp Later on, one must define the three parts of the body by providing two or three functions (remember that the cleanup routine is optional). These functions are named after the test case's identifier, and are .Fn _head , .Fn _body and .Fn _cleanup. None of these take parameters when executed. .Ss Program initialization The test program must define an .Fn atf_init_test_cases function, which is in charge of registering the test cases that will be executed at run time by using the .Fn atf_add_test_case function, which takes the name of a test case as its single parameter. This main function should not do anything else, except maybe sourcing auxiliary source files that define extra variables and functions. .Ss Configuration variables The test case has read-only access to the current configuration variables through the .Fn atf_config_has and .Fn atf_config_get methods. The former takes a single parameter specifying a variable name and returns a boolean indicating whether the variable is defined or not. The latter can take one or two parameters. If it takes only one, it specifies the variable from which to get the value, and this variable must be defined. If it takes two, the second one specifies a default value to be returned if the variable is not available. .Ss Access to the source directory It is possible to get the path to the test case's source directory from anywhere in the test program by using the .Fn atf_get_srcdir function. It is interesting to note that this can be used inside .Fn atf_init_test_cases to silently include additional helper files from the source directory. .Ss Requiring programs Aside from the .Va require.progs meta-data variable available in the header only, one can also check for additional programs in the test case's body by using the .Fn atf_require_prog function, which takes the base name or full path of a single binary. Relative paths are forbidden. If it is not found, the test case will be automatically skipped. .Ss Test case finalization The test case finalizes either when the body reaches its end, at which point the test is assumed to have .Em passed , or at any explicit call to .Fn atf_pass , .Fn atf_fail or .Fn atf_skip . These three functions terminate the execution of the test case immediately. The cleanup routine will be processed afterwards in a completely automated way, regardless of the test case's termination reason. .Pp .Fn atf_pass does not take any parameters. .Fn atf_fail and .Fn atf_skip take a single string parameter that describes why the test case failed or was skipped, respectively. It is very important to provide a clear error message in both cases so that the user can quickly know why the test did not pass. .Ss Expectations Everything explained in the previous section changes when the test case expectations are redefined by the programmer. .Pp Each test case has an internal state called .Sq expect that describes what the test case expectations are at any point in time. The value of this property can change during execution by any of: .Bl -tag -width indent .It Fn atf_expect_death "reason" "..." Expects the test case to exit prematurely regardless of the nature of the exit. .It Fn atf_expect_exit "exitcode" "reason" "..." Expects the test case to exit cleanly. If .Va exitcode is not .Sq -1 , .Xr atf-run 1 will validate that the exit code of the test case matches the one provided in this call. Otherwise, the exact value will be ignored. .It Fn atf_expect_fail "reason" Any failure raised in this mode is recorded, but such failures do not report the test case as failed; instead, the test case finalizes cleanly and is reported as .Sq expected failure ; this report includes the provided .Fa reason as part of it. If no error is raised while running in this mode, then the test case is reported as .Sq failed . .Pp This mode is useful to reproduce actual known bugs in tests. Whenever the developer fixes the bug later on, the test case will start reporting a failure, signaling the developer that the test case must be adjusted to the new conditions. In this situation, it is useful, for example, to set .Fa reason as the bug number for tracking purposes. .It Fn atf_expect_pass This is the normal mode of execution. In this mode, any failure is reported as such to the user and the test case is marked as .Sq failed . .It Fn atf_expect_signal "signo" "reason" "..." Expects the test case to terminate due to the reception of a signal. If .Va signo is not .Sq -1 , .Xr atf-run 1 will validate that the signal that terminated the test case matches the one provided in this call. Otherwise, the exact value will be ignored. .It Fn atf_expect_timeout "reason" "..." Expects the test case to execute for longer than its timeout. .El .Ss Helper functions for common checks .Fn atf_check [options] command [args] .Pp This function wraps the execution of the .Nm atf-check tool and makes the test case fail if the tool reports failure. You should always use this function instead of the tool in your scripts. For more details on the parameters of this function, refer to .Xr atf-check 1 . .Pp .Fn atf_check_equal expr1 expr2 .Pp This function takes two expressions, evaluates them and, if their results differ, aborts the test case with an appropriate failure message. .Sh EXAMPLES The following shows a complete test program with a single test case that validates the addition operator: .Bd -literal -offset indent atf_test_case addition addition_head() { atf_set "descr" "Sample tests for the addition operator" } addition_body() { atf_check_equal $((0 + 0)) 0 atf_check_equal $((0 + 1)) 1 atf_check_equal $((1 + 0)) 0 atf_check_equal $((1 + 1)) 2 atf_check_equal $((100 + 200)) 300 } atf_init_test_cases() { atf_add_test_case addition } .Ed .Pp This other example shows how to include a file with extra helper functions in the test program: .Bd -literal -offset indent .Ns ... definition of test cases ... atf_init_test_cases() { . $(atf_get_srcdir)/helper_functions.sh atf_add_test_case foo1 atf_add_test_case foo2 } .Ed .Pp This example demonstrates the use of the very useful .Fn atf_check function: .Bd -literal -offset indent # Check for silent output atf_check 'true' 0 null null # Check for silent output and failure atf_check 'false' 1 null null # Check for known stdout and silent stderr echo foo >expout atf_check 'echo foo' 0 expout null # Generate a file for later inspection atf_check 'ls' 0 stdout null grep foo ls || atf_fail "foo file not found in listing" .Ed .Sh SEE ALSO .Xr atf-sh 1 , .Xr atf-test-program 1 , .Xr atf-test-case 4 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-sh/atf-sh.1000644 024064 023255 00000004560 11734112744 020275 0ustar00eachsweng000000 000000 .\" .\" Automated Testing Framework (atf) .\" .\" Copyright (c) 2010 The NetBSD Foundation, Inc. .\" All rights reserved. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.

For those formats that write to a single file, specifying a .Sq - as the path will redirect the report to the standard output. .El .Sh SEE ALSO .Xr atf-config 1 , .Xr atf-sh-api 3 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-sh/atf-sh.cpp000644 024064 023255 00000011202 11734112744 020706 0ustar00eachsweng000000 000000 // // Automated Testing Framework (atf) // // Copyright (c) 2010 The NetBSD Foundation, Inc. // All rights reserved. // // Redistribution and use in source and binary forms, with or without // modification, are permitted provided that the following conditions // are met: // 1.

Fl o Ar fmtN:pathN .Nm .Fl h .Sh DESCRIPTION .Nm reads the output of .Nm atf-run and transforms it to different formats. Some of these are user-friendly and others are machine-parseable, which opens a wide range of possibilities to analyze the results of a test suite's execution. See .Sx Output formats below for more details on which these formats are. .Pp In the first synopsis form, .Nm reads the output of .Nm atf-run through its standard input and, if no .Fl o options are given, prints a user-friendly report on its standard output using the .Sq ticker format. If .Fl o options are provided (more than one are allowed), they specify the complete list of reports to generate. They are all generated simultaneously, and for obvious reasons, two reports cannot be written to the same file. Note that the default output is suppressed when .Fl o is provided. .Pp In the second synopsis form, .Nm will print information about all supported options and their purpose. .Pp The following options are available: .Bl -tag -width XoXfmtXpathXX .It Fl h Shows a short summary of all available options and their purpose. .It Fl o Ar fmt:path Adds a new output format. .Ar fmt is one of the formats described later on in .Sx Output formats . .Ar path specifies where the report will be written to. Depending on the chosen format, this may refer to a single file or to a directory. For those formats that write to a single file, specifying a .Sq - as the path will redirect the report to the standard output. .El .Ss Output formats The following output formats are allowed: .Bl -tag -width tickerXX .It csv A machine-parseable Comma-Separated Values (CSV) file. This file contains the results for all test cases and test programs. Test cases are logged using the following syntax: .Bd -literal -offset indent tc, test-program, test-case, result[, reason] .Ed .Pp The .Sq result field for test cases is always one of .Sq passed , .Sq skipped or .Sq failed . The last two are always followed by a reason. .Pp Test programs are logged with the following syntax: .Bd -literal -offset indent tp, test-program, result[, reason] .Ed .Pp In this case, the .Sq result can be one of: .Sq passed , which denotes test programs that ran without any failure; .Sq failed , which refers to test programs in which one or more test cases failed; or .Sq bogus , which mentions those test programs that failed to execute by some reason. The reason file is only available in the last case. .Pp You should not rely on the order of the entries in the resulting output. .It ticker A user-friendly report that shows the progress of the test suite's execution as it operates. This type of report should always be redirected to a virtual terminal, not a file, as it may use control sequences that will make the output unreadable in regular files. .It xml A report contained in a single XML file. Ideal for later processing with .Xr xsltproc 1 to generate nice HTML reports. .El .Sh EXAMPLES The most simple way of running a test suite is to pipe the output of .Nm atf-run through .Nm without any additional flags. This will use the default output format, which is suitable to most users: .Bd -literal -offset indent atf-run | atf-report .Ed .Pp In some situations, it may be interesting to get a machine-parseable file aside from the standard report. This can be done as follows: .Bd -literal -offset indent atf-run | atf-report -o csv:testsuite.csv -o ticker:- .Ed .Pp Or if the standard report is not desired, thus achieving completely silent operation: atf-run | atf-report -o csv:testsuite.csv .Sh SEE ALSO .Xr atf-run 1 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-report/atf-report.cpp000644 024064 023255 00000047460 11734112744 022527 0ustar00eachsweng000000 000000 // // Automated Testing Framework (atf) // // Copyright (c) 2007, 2008 The NetBSD Foundation, Inc. // All rights reserved. // // Redistribution and use in source and binary forms, with or without // modification, are permitted provided that the following conditions // are met: // 1.

Static configuration refers to all those values for settings that were built into the ATF binaries at build time. .Pp In the first synopsis form, .Nm will print variable-value pairs for all built-in static variables if no variable names are provided as arguments. If any is provided, it will only print the variable-value pairs for those variables. The output of the utility does not use the .Sq = symbol to separate the variable name from its corresponding value in an attempt to avoid sourcing the output in shell scripts or Makefiles. If you need to do that, the .Fl t flag allows you to query the value of individual variables without any surrounding text. .Pp In the second synopsis form, .Nm will print information about all supported options and their purpose. .Pp The following options are available: .Bl -tag -width flag .It Fl h Shows a short summary of all available options and their purpose. .It Fl t Changes the output of the utility to show the variable values, one per line, without the variable names. .El .Ss Static configuration variables The following list describes all the variables that are part of ATF's static configuration: .Bl -tag -width atfXbuildXcppflagsXX .It Va atf_arch The architecture name detected by ATF. This is derived from .Va atf_machine because it is a subset of it. Given that this name might be misdetected, it is provided to the user as a configuration variable so that he can fix its value temporarily until a real fix is incorporated into mainstream sources. .It Va atf_build_cc The C compiler used by the ATF checks that provide build-time tests. .It Va atf_build_cflags The C compiler flags used by the ATF checks that provide build-time tests. .It Va atf_build_cpp The C/C++ preprocessor used by the ATF checks that provide build-time tests. .It Va atf_build_cppflags The C/C++ preprocessor flags used by the ATF checks that provide build-time tests. .It Va atf_build_cxx The C++ compiler used by the ATF checks that provide build-time tests. .It Va atf_build_cxxflags The C++ compiler flags used by the ATF checks that provide build-time tests. .It Va atf_confdir The path to the directory that contains the system-wide configuration files for ATF. .It Va atf_includedir The path to the directory that contains the ATF header files. .It Va atf_libdir The path to the directory that contains the ATF libraries. .It Va atf_libexecdir The path to the directory that contains the auxiliary utilities of ATF, used internally by the public tools. .It Va atf_machine The machine type name detected by ATF. This should not be tunable but is provided for symmetry with .Va atf_arch . .It Va atf_pkgdatadir The path to the directory that contains the files that form the ATF's shell-scripting library. .It Va atf_shell The path to the shell interpreter that will be used by ATF. .It Va atf_workdir The path to the temporary directory that the utilities and the test programs will use to store temporary files in. .El .Sh ENVIRONMENT Every variable that is part of the static configuration can be overridden at run-time by defining an environment variable. This environment variable has the exact same name as the one shown by .Nm except that the name is all composed of uppercase letters. .Pp In general, empty values in the environment will be ignored unless otherwise noted below. .Pp The recognized environment variables are: .Bl -tag -width ATFXBUILDXCPPFLAGSXX .It Ev ATF_ARCH Overrides the built-in value of .Va atf_arch . .It Ev ATF_BUILD_CC Overrides the built-in value of .Va atf_build_cc . .It Ev ATF_BUILD_CFLAGS Overrides the built-in value of .Va atf_build_cflags .

Empty values are allowed. .It Ev ATF_BUILD_CXX Overrides the built-in value of .Va atf_build_cxx . .It Ev ATF_BUILD_CXXFLAGS Overrides the built-in value of .Va atf_build_cxxflags . Empty values are allowed. .It Ev ATF_CONFDIR Overrides the built-in value of .Va atf_confdir . .It Ev ATF_INCLUDEDIR Overrides the built-in value of .Va atf_includedir . .It Ev ATF_LIBDIR Overrides the built-in value of .Va atf_libdir . .It Ev ATF_LIBEXECDIR Overrides the built-in value of .Va atf_libexecdir . .It Ev ATF_MACHINE Overrides the built-in value of .Va atf_machine . .It Ev ATF_PKGDATADIR Overrides the built-in value of .Va atf_pkgdatadir . .It Ev ATF_SHELL Overrides the built-in value of .Va atf_shell . .It Ev ATF_WORKDIR Overrides the built-in value of .Va atf_workdir . .El .Sh SEE ALSO .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-config/atf-config.cpp000644 024064 023255 00000007503 11734112744 022405 0ustar00eachsweng000000 000000 // // Automated Testing Framework (atf) // // Copyright (c) 2007, 2008 The NetBSD Foundation, Inc. // All rights reserved. // // Redistribution and use in source and binary forms, with or without // modification, are permitted provided that the following conditions // are met: // 1.

To define test cases, one can use the .Fn ATF_TC , .Fn ATF_TC_WITH_CLEANUP or the .Fn ATF_TC_WITHOUT_HEAD macros, which take a single parameter specifiying the test case's name. .Fn ATF_TC , requires to define a head and a body for the test case, .Fn ATF_TC_WITH_CLEANUP requires to define a head, a body and a cleanup for the test case and .Fn ATF_TC_WITHOUT_HEAD requires only a body for the test case. It is important to note that these .Em do not set the test case up for execution when the program is run. In order to do so, a later registration is needed with the .Fn ATF_TP_ADD_TC macro detailed in .Sx Program initialization . .Pp Later on, one must define the three parts of the body by means of three functions. Their headers are given by the .Fn ATF_TC_HEAD , .Fn ATF_TC_BODY and .Fn ATF_TC_CLEANUP macros, all of which take the test case name provided to the .Fn ATF_TC .Fn ATF_TC_WITH_CLEANUP , or .Fn ATF_TC_WITHOUT_HEAD macros and the name of the variable that will hold a pointer to the test case data. Following each of these, a block of code is expected, surrounded by the opening and closing brackets. .Ss Program initialization The library provides a way to easily define the test program's .Fn main function. You should never define one on your own, but rely on the library to do it for you. This is done by using the .Fn ATF_TP_ADD_TCS macro, which is passed the name of the object that will hold the test cases; i.e. the test program instance. This name can be whatever you want as long as it is a valid variable identifier. .Pp After the macro, you are supposed to provide the body of a function, which should only use the .Fn ATF_TP_ADD_TC macro to register the test cases the test program will execute and return a success error code. The first parameter of this macro matches the name you provided in the former call. The success status can be returned using the .Fn atf_no_error function. .Ss Header definitions The test case's header can define the meta-data by using the .Fn atf_tc_set_md_var method, which takes three parameters: the first one points to the test case data, the second one specifies the meta-data variable to be set and the third one specifies its value. Both of them are strings. .Ss Configuration variables The test case has read-only access to the current configuration variables by means of the .Ft bool .Fn atf_tc_has_config_var , .Ft const char * .Fn atf_tc_get_config_var , .Ft const char * .Fn atf_tc_get_config_var_wd , .Ft bool .Fn atf_tc_get_config_var_as_bool , .Ft bool .Fn atf_tc_get_config_var_as_bool_wd , .Ft long .Fn atf_tc_get_config_var_as_long , and the .Ft long .Fn atf_tc_get_config_var_as_long_wd functions, which can be called in any of the three parts of a test case. .Ss Access to the source directory It is possible to get the path to the test case's source directory from any of its three components by querying the .Sq srcdir configuration variable. .Ss Requiring programs Aside from the .Va require.progs meta-data variable available in the header only, one can also check for additional programs in the test case's body by using the .Fn atf_tc_require_prog function, which takes the base name or full path of a single binary. Relative paths are forbidden. If it is not found, the test case will be automatically skipped. .Ss Test case finalization The test case finalizes either when the body reaches its end, at which point the test is assumed to have .Em passed , unless any non-fatal errors were raised using .Fn atf_tc_fail_nonfatal , or at any explicit call to .Fn atf_tc_pass , .Fn atf_tc_fail or .Fn atf_tc_skip . These three functions terminate the execution of the test case immediately. The cleanup routine will be processed afterwards in a completely automated way, regardless of the test case's termination reason. .Pp .Fn atf_tc_pass does not take any parameters. .Fn atf_tc_fail , .Fn atf_tc_fail_nonfatal and .Fn atf_tc_skip take a format string and a variable list of parameters, which describe, in a user-friendly manner, why the test case failed or was skipped, respectively. It is very important to provide a clear error message in both cases so that the user can quickly know why the test did not pass. .Ss Expectations Everything explained in the previous section changes when the test case expectations are redefined by the programmer. .Pp Each test case has an internal state called .Sq expect that describes what the test case expectations are at any point in time. The value of this property can change during execution by any of: .Bl -tag -width indent .It Fn atf_tc_expect_death "reason" "..." Expects the test case to exit prematurely regardless of the nature of the exit. .It Fn atf_tc_expect_exit "exitcode" "reason" "..." Expects the test case to exit cleanly. If .Va exitcode is not .Sq -1 , .Xr atf-run 1 will validate that the exit code of the test case matches the one provided in this call. Otherwise, the exact value will be ignored. .It Fn atf_tc_expect_fail "reason" "..." Any failure (be it fatal or non-fatal) raised in this mode is recorded. However, such failures do not report the test case as failed; instead, the test case finalizes cleanly and is reported as .Sq expected failure ; this report includes the provided .Fa reason as part of it. If no error is raised while running in this mode, then the test case is reported as .Sq failed . .Pp This mode is useful to reproduce actual known bugs in tests. Whenever the developer fixes the bug later on, the test case will start reporting a failure, signaling the developer that the test case must be adjusted to the new conditions. In this situation, it is useful, for example, to set .Fa reason as the bug number for tracking purposes. .It Fn atf_tc_expect_pass This is the normal mode of execution. In this mode, any failure is reported as such to the user and the test case is marked as .Sq failed . .It Fn atf_tc_expect_signal "signo" "reason" "..." Expects the test case to terminate due to the reception of a signal. If .Va signo is not .Sq -1 , .Xr atf-run 1 will validate that the signal that terminated the test case matches the one provided in this call. Otherwise, the exact value will be ignored. .It Fn atf_tc_expect_timeout "reason" "..." Expects the test case to execute for longer than its timeout. .El .Ss Helper macros for common checks The library provides several macros that are very handy in multiple situations. These basically check some condition after executing a given statement or processing a given expression and, if the condition is not met, they report the test case as failed. .Pp The .Sq REQUIRE variant of the macros immediately abort the test case as soon as an error condition is detected by calling the .Fn atf_tc_fail function. Use this variant whenever it makes now sense to continue the execution of a test case when the checked condition is not met. The .Sq CHECK variant, on the other hand, reports a failure as soon as it is encountered using the .Fn atf_tc_fail_nonfatal function, but the execution of the test case continues as if nothing had happened. Use this variant whenever the checked condition is important as a result of the test case, but there are other conditions that can be subsequently checked on the same run without aborting. .Pp Additionally, the .Sq MSG variants take an extra set of parameters to explicitly specify the failure message. This failure message is formatted according to the .Xr printf 3 formatters. .Pp .Fn ATF_CHECK , .Fn ATF_CHECK_MSG , .Fn ATF_REQUIRE and .Fn ATF_REQUIRE_MSG take an expression and fail if the expression evaluates to false. .Pp .Fn ATF_CHECK_EQ , .Fn ATF_CHECK_EQ_MSG , .Fn ATF_REQUIRE_EQ and .Fn ATF_REQUIRE_EQ_MSG take two expressions and fail if the two evaluated values are not equal. .Pp .Fn ATF_CHECK_STREQ , .Fn ATF_CHECK_STREQ_MSG , .Fn ATF_REQUIRE_STREQ and .Fn ATF_REQUIRE_STREQ_MSG take two strings and fail if the two are not equal character by character. .Pp .Fn ATF_CHECK_ERRNO and .Fn ATF_REQUIRE_ERRNO take, first, the error code that the check is expecting to find in the .Va errno variable and, second, a boolean expression that, if evaluates to true, means that a call failed and .Va errno has to be checked against the first value. .Sh EXAMPLES The following shows a complete test program with a single test case that validates the addition operator: .Bd -literal -offset indent #include ATF_TC(addition); ATF_TC_HEAD(addition, tc) { atf_tc_set_md_var(tc, "descr", "Sample tests for the addition operator"); } ATF_TC_BODY(addition, tc) { ATF_CHECK_EQ(0 + 0, 0); ATF_CHECK_EQ(0 + 1, 1); ATF_CHECK_EQ(1 + 0, 1); ATF_CHECK_EQ(1 + 1, 2); ATF_CHECK_EQ(100 + 200, 300); } ATF_TC(string_formatting); ATF_TC_HEAD(string_formatting, tc) { atf_tc_set_md_var(tc, "descr", "Sample tests for the snprintf"); } ATF_TC_BODY(string_formatting, tc) { char buf[1024]; snprintf(buf, sizeof(buf), "a %s", "string"); ATF_CHECK_STREQ_MSG("a string", buf, "%s is not working"); } ATF_TC(open_failure); ATF_TC_HEAD(open_failure, tc) { atf_tc_set_md_var(tc, "descr", "Sample tests for the open function"); } ATF_TC_BODY(open_failure, tc) { ATF_CHECK_ERRNO(ENOENT, open("non-existent", O_RDONLY) == -1); } ATF_TC(known_bug); ATF_TC_HEAD(known_bug, tc) { atf_tc_set_md_var(tc, "descr", "Reproduces a known bug"); } ATF_TC_BODY(known_bug, tc) { atf_tc_expect_fail("See bug number foo/bar"); ATF_CHECK_EQ(3, 1 + 1); atf_tc_expect_pass(); ATF_CHECK_EQ(3, 1 + 2); } ATF_TP_ADD_TCS(tp) { ATF_TP_ADD_TC(tp, addition); ATF_TP_ADD_TC(tp, string_formatting); ATF_TP_ADD_TC(tp, open_failure); ATF_TP_ADD_TC(tp, known_bug); return atf_no_error(); } .Ed .Sh SEE ALSO .Xr atf-test-program 1 , .Xr atf-test-case 4 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-c/atf-c.pc.in000644 024064 023255 00000000332 11734112744 020555 0ustar00eachsweng000000 000000 # ATF pkg-config file cc=__CC__ includedir=__INCLUDEDIR__ libdir=__LIBDIR__ Name: atf-c Description: Automated Testing Framework (C binding) Version: __ATF_VERSION__ Cflags: -I${includedir} Libs: -L${libdir} -latf-c bind-9.6-ESV-R6/unit/atf-src/atf-c/atf_c_test.c000644 024064 023255 00000003722 11734112744 021117 0ustar00eachsweng000000 000000 /* * Automated Testing Framework (atf) * * Copyright (c) 2008, 2009 The NetBSD Foundation, Inc. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

This interface is backed by a C++ implementation, but this fact is hidden from the developer as much as possible through the use of macros to simplify programming. However, the use of C++ is not hidden everywhere and while you can implement test cases without knowing anything at all about the object model underneath the provided calls, you might need some minimum notions of the language in very specific circumstances. .Pp C++-based test programs always follow this template: .Bd -literal -offset indent extern "C" { .Ns ... C-specific includes go here ... } .Ns ... C++-specific includes go here ... #include ATF_TEST_CASE(tc1); ATF_TEST_CASE_HEAD(tc1) { ... first test case's header ... } ATF_TEST_CASE_BODY(tc1) { ... first test case's body ... } ATF_TEST_CASE_WITH_CLEANUP(tc2); ATF_TEST_CASE_HEAD(tc2) { ... second test case's header ... } ATF_TEST_CASE_BODY(tc2) { ... second test case's body ... } ATF_TEST_CASE_CLEANUP(tc2) { ... second test case's cleanup ... } ATF_TEST_CASE(tc3); ATF_TEST_CASE_BODY(tc3) { ... third test case's body ... } .Ns ... additional test cases ... ATF_INIT_TEST_CASES(tcs) { ATF_ADD_TEST_CASE(tcs, tc1); ATF_ADD_TEST_CASE(tcs, tc2); ATF_ADD_TEST_CASE(tcs, tc3); ... add additional test cases ... } .Ed .Ss Definition of test cases Test cases have an identifier and are composed of three different parts: the header, the body and an optional cleanup routine, all of which are described in .Xr atf-test-case 4 . To define test cases, one can use the .Fn ATF_TEST_CASE , .Fn ATF_TEST_CASE_WITH_CLEANUP or the .Fn ATF_TEST_CASE_WITHOUT_HEAD macros, which take a single parameter specifiying the test case's name. .Fn ATF_TEST_CASE , requires to define a head and a body for the test case, .Fn ATF_TEST_CASE_WITH_CLEANUP requires to define a head, a body and a cleanup for the test case and .Fn ATF_TEST_CASE_WITHOUT_HEAD requires only a body for the test case. It is important to note that these .Em do not set the test case up for execution when the program is run. In order to do so, a later registration is needed through the .Fn ATF_ADD_TEST_CASE macro detailed in .Sx Program initialization . .Pp Later on, one must define the three parts of the body by means of three functions. Their headers are given by the .Fn ATF_TEST_CASE_HEAD , .Fn ATF_TEST_CASE_BODY and .Fn ATF_TEST_CASE_CLEANUP macros, all of which take the test case's name. Following each of these, a block of code is expected, surrounded by the opening and closing brackets. .Ss Program initialization The library provides a way to easily define the test program's .Fn main function. You should never define one on your own, but rely on the library to do it for you. This is done by using the .Fn ATF_INIT_TEST_CASES macro, which is passed the name of the list that will hold the test cases. This name can be whatever you want as long as it is a valid variable value. .Pp After the macro, you are supposed to provide the body of a function, which should only use the .Fn ATF_ADD_TEST_CASE macro to register the test cases the test program will execute. The first parameter of this macro matches the name you provided in the former call. .Ss Header definitions The test case's header can define the meta-data by using the .Fn set method, which takes two parameters: the first one specifies the meta-data variable to be set and the second one specifies its value. Both of them are strings. .Ss Configuration variables The test case has read-only access to the current configuration variables by means of the .Ft bool .Fn has_config_var and the .Ft std::string .Fn get_config_var methods, which can be called in any of the three parts of a test case. .Ss Access to the source directory It is possible to get the path to the test case's source directory from any of its three components by querying the .Sq srcdir configuration variable. .Ss Requiring programs Aside from the .Va require.progs meta-data variable available in the header only, one can also check for additional programs in the test case's body by using the .Fn require_prog function, which takes the base name or full path of a single binary. Relative paths are forbidden. If it is not found, the test case will be automatically skipped. .Ss Test case finalization The test case finalizes either when the body reaches its end, at which point the test is assumed to have .Em passed , or at any explicit call to .Fn ATF_PASS , .Fn ATF_FAIL or .Fn ATF_SKIP . These three macros terminate the execution of the test case immediately. The cleanup routine will be processed afterwards in a completely automated way, regardless of the test case's termination reason. .Pp .Fn ATF_PASS does not take any parameters. .Fn ATF_FAIL and .Fn ATF_SKIP take a single string that describes why the test case failed or was skipped, respectively. It is very important to provide a clear error message in both cases so that the user can quickly know why the test did not pass. .Ss Expectations Everything explained in the previous section changes when the test case expectations are redefined by the programmer. .Pp Each test case has an internal state called .Sq expect that describes what the test case expectations are at any point in time. The value of this property can change during execution by any of: .Bl -tag -width indent .It Fn expect_death "reason" Expects the test case to exit prematurely regardless of the nature of the exit. .It Fn expect_exit "exitcode" "reason" Expects the test case to exit cleanly. If .Va exitcode is not .Sq -1 , .Xr atf-run 1 will validate that the exit code of the test case matches the one provided in this call. Otherwise, the exact value will be ignored. .It Fn expect_fail "reason" Any failure (be it fatal or non-fatal) raised in this mode is recorded. However, such failures do not report the test case as failed; instead, the test case finalizes cleanly and is reported as .Sq expected failure ; this report includes the provided .Fa reason as part of it. If no error is raised while running in this mode, then the test case is reported as .Sq failed . .Pp This mode is useful to reproduce actual known bugs in tests. Whenever the developer fixes the bug later on, the test case will start reporting a failure, signaling the developer that the test case must be adjusted to the new conditions. In this situation, it is useful, for example, to set .Fa reason as the bug number for tracking purposes. .It Fn expect_pass This is the normal mode of execution. In this mode, any failure is reported as such to the user and the test case is marked as .Sq failed . .It Fn expect_race "reason" Any failure or timeout during the execution of the test case will be considered as if a race condition has been triggered and reported as such. If no problems arise, the test will continue execution as usual. .It Fn expect_signal "signo" "reason" Expects the test case to terminate due to the reception of a signal. If .Va signo is not .Sq -1 , .Xr atf-run 1 will validate that the signal that terminated the test case matches the one provided in this call. Otherwise, the exact value will be ignored. .It Fn expect_timeout "reason" Expects the test case to execute for longer than its timeout. .El .Ss Helper macros for common checks The library provides several macros that are very handy in multiple situations. These basically check some condition after executing a given statement or processing a given expression and, if the condition is not met, they automatically call .Fn ATF_FAIL with an appropriate error message. .Pp .Fn ATF_REQUIRE takes an expression and raises a failure if it evaluates to false. .Pp .Fn ATF_REQUIRE_EQ takes two expressions and raises a failure if the two do not evaluate to the same exact value. .Pp .Fn ATF_REQUIRE_MATCH takes a regular expression and a string and raises a failure if the regular expression does not match the string. .Pp .Fn ATF_REQUIRE_THROW takes the name of an exception and a statement and raises a failure if the statement does not throw the specified exception. .Fn ATF_REQUIRE_THROW_EQ takes the name of an exception, a regular expresion and a statement and raises a failure if the statement does not throw the specified exception and if the message of the exception does not match the regular expression. .Pp .Fn ATF_CHECK_ERRNO and .Fn ATF_REQUIRE_ERRNO take, first, the error code that the check is expecting to find in the .Va errno variable and, second, a boolean expression that, if evaluates to true, means that a call failed and .Va errno has to be checked against the first value. .Sh EXAMPLES The following shows a complete test program with a single test case that validates the addition operator: .Bd -literal -offset indent #include ATF_TEST_CASE(addition); ATF_TEST_CASE_HEAD(addition) { set("descr", "Sample tests for the addition operator"); } ATF_TEST_CASE_BODY(addition) { ATF_REQUIRE_EQ(0 + 0, 0); ATF_REQUIRE_EQ(0 + 1, 1); ATF_REQUIRE_EQ(1 + 0, 1); ATF_REQUIRE_EQ(1 + 1, 2); ATF_REQUIRE_EQ(100 + 200, 300); } ATF_TEST_CASE(open_failure); ATF_TEST_CASE_HEAD(open_failure) { set("descr", "Sample tests for the open function"); } ATF_TEST_CASE_BODY(open_failure) { ATF_REQUIRE_ERRNO(ENOENT, open("non-existent", O_RDONLY) == -1); } ATF_TEST_CASE(known_bug); ATF_TEST_CASE_HEAD(known_bug) { set("descr", "Reproduces a known bug"); } ATF_TEST_CASE_BODY(known_bug) { expect_fail("See bug number foo/bar"); ATF_REQUIRE_EQ(3, 1 + 1); expect_pass(); ATF_REQUIRE_EQ(3, 1 + 2); } ATF_INIT_TEST_CASES(tcs) { ATF_ADD_TEST_CASE(tcs, addition); ATF_ADD_TEST_CASE(tcs, open_failure); ATF_ADD_TEST_CASE(tcs, known_bug); } .Ed .Sh SEE ALSO .Xr atf-test-program 1 , .Xr atf-test-case 4 , .Xr atf 7 bind-9.6-ESV-R6/unit/atf-src/atf-c++/atf-c++.pc.in000644 024064 023255 00000000352 11734112744 021033 0ustar00eachsweng000000 000000 # ATF pkg-config file cxx=__CXX__ includedir=__INCLUDEDIR__ libdir=__LIBDIR__ Name: atf-c++ Description: Automated Testing Framework (C++ binding) Version: __ATF_VERSION__ Cflags: -I${includedir} Libs: -L${libdir} -latf-c++ -latf-c bind-9.6-ESV-R6/unit/atf-src/atf-c++/atf_c++_test.cpp000644 024064 023255 00000003706 11734112744 021735 0ustar00eachsweng000000 000000 // // Automated Testing Framework (atf) // // Copyright (c) 2009 The NetBSD Foundation, Inc. // All rights reserved. // // Redistribution and use in source and binary forms, with or without // modification, are permitted provided that the following conditions // are met: // 1.

It holds a socket and other data needed for communicating with a resolver daemon. The new lwres_context_t is returned through contextp, a pointer to a lwres_context_t pointer. This lwres_context_t pointer must initially be NULL, and is modified to point to the newly created lwres_context_t. When the lightweight resolver needs to perform dynamic memory allocation, it will call malloc_function to allocate memory and free_function to free it. If malloc_function and free_function are NULL, memory is allocated using malloc and free. It is not permitted to have a NULL malloc_function and a non-NULL free_function or vice versa. arg is passed as the first parameter to the memory allocation functions. If malloc_function and free_function are NULL, arg is unused and should be passed as NULL. Once memory for the structure has been allocated, it is initialized using lwres_conf_init() and returned via *contextp. lwres_context_destroy() destroys a #lwres_context_t, closing its socket. contextp is a pointer to a pointer to the context that is to be destroyed. The pointer will be set to NULL when the context has been destroyed. The context holds a serial number that is used to identify resolver request packets and associate responses with the corresponding requests. This serial number is controlled using lwres_context_initserial() and lwres_context_nextserial(). lwres_context_initserial() sets the serial number for context *ctx to serial. lwres_context_nextserial() increments the serial number and returns the previous value. Memory for a lightweight resolver context is allocated and freed using lwres_context_allocmem() and lwres_context_freemem(). These use whatever allocations were defined when the context was created with lwres_context_create(). lwres_context_allocmem() allocates len bytes of memory and if successful returns a pointer to the allocated storage. lwres_context_freemem() frees len bytes of space starting at location mem. lwres_context_sendrecv() performs I/O for the context ctx. Data are read and written from the context's socket. It writes data from sendbase -- typically a lightweight resolver query packet -- and waits for a reply which is copied to the receive buffer at recvbase. The number of bytes that were written to this receive buffer is returned in *recvd_len. \section context_return Return Values lwres_context_create() returns #LWRES_R_NOMEMORY if memory for the struct lwres_context could not be allocated, #LWRES_R_SUCCESS otherwise.

The function is the * lightweight resolver's implementation of getaddrinfo() as defined in * RFC2133. hostname and servname are pointers to null-terminated strings * or NULL. hostname is either a host name or a numeric host address * string: a dotted decimal IPv4 address or an IPv6 address. servname is * either a decimal port number or a service name as listed in * /etc/services. * * If the operating system does not provide a struct addrinfo, the * following structure is used: * * \code * struct addrinfo { * int ai_flags; // AI_PASSIVE, AI_CANONNAME * int ai_family; // PF_xxx * int ai_socktype; // SOCK_xxx * int ai_protocol; // 0 or IPPROTO_xxx for IPv4 and IPv6 * size_t ai_addrlen; // length of ai_addr * char *ai_canonname; // canonical name for hostname * struct sockaddr *ai_addr; // binary address * struct addrinfo *ai_next; // next structure in linked list * }; * \endcode * * * hints is an optional pointer to a struct addrinfo. This structure can * be used to provide hints concerning the type of socket that the caller * supports or wishes to use. The caller can supply the following * structure elements in *hints: * *
      *
    • ai_family: * The protocol family that should be used. When ai_family is set * to PF_UNSPEC, it means the caller will accept any protocol * family supported by the operating system.
      • * *
    • ai_socktype: * denotes the type of socket -- SOCK_STREAM, SOCK_DGRAM or * SOCK_RAW -- that is wanted. When ai_socktype is zero the caller * will accept any socket type.
      • * *
    • ai_protocol: * indicates which transport protocol is wanted: IPPROTO_UDP or * IPPROTO_TCP. If ai_protocol is zero the caller will accept any * protocol.
      • * *
    • ai_flags: * Flag bits. If the AI_CANONNAME bit is set, a successful call to * lwres_getaddrinfo() will return a null-terminated string * containing the canonical name of the specified hostname in * ai_canonname of the first addrinfo structure returned. Setting * the AI_PASSIVE bit indicates that the returned socket address * structure is intended for used in a call to bind(2). In this * case, if the hostname argument is a NULL pointer, then the IP * address portion of the socket address structure will be set to * INADDR_ANY for an IPv4 address or IN6ADDR_ANY_INIT for an IPv6 * address.

      * * When ai_flags does not set the AI_PASSIVE bit, the returned * socket address structure will be ready for use in a call to * connect(2) for a connection-oriented protocol or connect(2), * sendto(2), or sendmsg(2) if a connectionless protocol was * chosen. The IP address portion of the socket address structure * will be set to the loopback address if hostname is a NULL * pointer and AI_PASSIVE is not set in ai_flags.

      * * If ai_flags is set to AI_NUMERICHOST it indicates that hostname * should be treated as a numeric string defining an IPv4 or IPv6 * address and no name resolution should be attempted. *
    * * All other elements of the struct addrinfo passed via hints must be * zero. * * A hints of NULL is treated as if the caller provided a struct addrinfo * initialized to zero with ai_familyset to PF_UNSPEC. * * After a successful call to lwres_getaddrinfo(), *res is a pointer to a * linked list of one or more addrinfo structures. Each struct addrinfo * in this list cn be processed by following the ai_next pointer, until a * NULL pointer is encountered. The three members ai_family, ai_socktype, * and ai_protocol in each returned addrinfo structure contain the * corresponding arguments for a call to socket(2). For each addrinfo * structure in the list, the ai_addr member points to a filled-in socket * address structure of length ai_addrlen. * * All of the information returned by lwres_getaddrinfo() is dynamically * allocated: the addrinfo structures, and the socket address structures * and canonical host name strings pointed to by the addrinfostructures. * Memory allocated for the dynamically allocated structures created by a * successful call to lwres_getaddrinfo() is released by * lwres_freeaddrinfo(). ai is a pointer to a struct addrinfo created by * a call to lwres_getaddrinfo(). * * \section lwresreturn RETURN VALUES * * lwres_getaddrinfo() returns zero on success or one of the error codes * listed in gai_strerror() if an error occurs.

The hostname is of length * hostlen and is returned via *host. The maximum length of the hostname * is 1025 bytes: #NI_MAXHOST. * * The name of the service associated with the port number in sa is * returned in *serv. It is servlen bytes long. The maximum length of the * service name is #NI_MAXSERV - 32 bytes. * * The flags argument sets the following bits: * * \li #NI_NOFQDN: * A fully qualified domain name is not required for local hosts. * The local part of the fully qualified domain name is returned * instead. * * \li #NI_NUMERICHOST * Return the address in numeric form, as if calling inet_ntop(), * instead of a host name. * * \li #NI_NAMEREQD * A name is required. If the hostname cannot be found in the DNS * and this flag is set, a non-zero error code is returned. If the * hostname is not found and the flag is not set, the address is * returned in numeric form. * * \li #NI_NUMERICSERV * The service name is returned as a digit string representing the * port number. * * \li #NI_DGRAM * Specifies that the service being looked up is a datagram * service, and causes getservbyport() to be called with a second * argument of "udp" instead of its default of "tcp". This is * required for the few ports (512-514) that have different * services for UDP and TCP. * * \section getnameinfo_return Return Values * * lwres_getnameinfo() returns 0 on success or a non-zero error code if * an error occurs. * * \section getname_see See Also * * RFC2133, getservbyport(), * lwres_getnamebyaddr(). lwres_net_ntop(). * * \section getnameinfo_bugs Bugs * * RFC2133 fails to define what the nonzero return values of * getnameinfo() are. */ #include #include #include #include #include #include #include "print_p.h" #include "assert_p.h" #define SUCCESS 0 /*% afd structure definition */ static struct afd { int a_af; size_t a_addrlen; size_t a_socklen; } afdl [] = { /*! * First entry is linked last... */ { AF_INET, sizeof(struct in_addr), sizeof(struct sockaddr_in) }, { AF_INET6, sizeof(struct in6_addr), sizeof(struct sockaddr_in6) }, {0, 0, 0}, }; #define ENI_NOSERVNAME 1 #define ENI_NOHOSTNAME 2 #define ENI_MEMORY 3 #define ENI_SYSTEM 4 #define ENI_FAMILY 5 #define ENI_SALEN 6 #define ENI_NOSOCKET 7 /*! * The test against 0 is there to keep the Solaris compiler * from complaining about "end-of-loop code not reached". */ #define ERR(code) \ do { result = (code); \ if (result != 0) goto cleanup; \ } while (0) /*% lightweight resolver socket address structure to hostname and service name */ int lwres_getnameinfo(const struct sockaddr *sa, size_t salen, char *host, size_t hostlen, char *serv, size_t servlen, int flags) { struct afd *afd; struct servent *sp; unsigned short port; #ifdef LWRES_PLATFORM_HAVESALEN size_t len; #endif int family, i; const void *addr; char *p; #if 0 unsigned long v4a; unsigned char pfx; #endif char numserv[sizeof("65000")]; char numaddr[sizeof("abcd:abcd:abcd:abcd:abcd:abcd:255.255.255.255") + 1 + sizeof("4294967295")]; const char *proto; lwres_uint32_t lwf = 0; lwres_context_t *lwrctx = NULL; lwres_gnbaresponse_t *by = NULL; int result = SUCCESS; int n; if (sa == NULL) ERR(ENI_NOSOCKET); #ifdef LWRES_PLATFORM_HAVESALEN len = sa->sa_len; if (len != salen) ERR(ENI_SALEN); #endif family = sa->sa_family; for (i = 0; afdl[i].a_af; i++) if (afdl[i].a_af == family) { afd = &afdl[i]; goto found; } ERR(ENI_FAMILY); found: if (salen != afd->a_socklen) ERR(ENI_SALEN); switch (family) { case AF_INET: port = ((const struct sockaddr_in *)sa)->sin_port; addr = &((const struct sockaddr_in *)sa)->sin_addr.s_addr; break; case AF_INET6: port = ((const struct sockaddr_in6 *)sa)->sin6_port; addr = ((const struct sockaddr_in6 *)sa)->sin6_addr.s6_addr; break; default: port = 0; addr = NULL; POST(port); POST(addr); INSIST(0); } proto = (flags & NI_DGRAM) ?

They are based on, and similar * to, the isc_buffer_ functions in the ISC library. * * A buffer is a region of memory, together with a set of related * subregions. The used region and the available region are disjoint, and * their union is the buffer's region. The used region extends from the * beginning of the buffer region to the last used byte. The available * region extends from one byte greater than the last used byte to the * end of the buffer's region. The size of the used region can be changed * using various buffer commands. Initially, the used region is empty. * * The used region is further subdivided into two disjoint regions: the * consumed region and the remaining region. The union of these two * regions is the used region. The consumed region extends from the * beginning of the used region to the byte before the current offset (if * any). The remaining region the current pointer to the end of the used * region. The size of the consumed region can be changed using various * buffer commands. Initially, the consumed region is empty. * * The active region is an (optional) subregion of the remaining region. * It extends from the current offset to an offset in the remaining * region. Initially, the active region is empty. If the current offset * advances beyond the chosen offset, the active region will also be * empty. * * * \verbatim * /------------entire length---------------\\ * /----- used region -----\\/-- available --\\ * +----------------------------------------+ * | consumed | remaining | | * +----------------------------------------+ * a b c d e * * a == base of buffer. * b == current pointer.

Meaningful between b and d. * d == used pointer. * e == length of buffer. * * a-e == entire length of buffer. * a-d == used region. * a-b == consumed region. * b-d == remaining region. * b-c == optional active region. * \endverbatim * * lwres_buffer_init() initializes the lwres_buffer_t *b and assocates it * with the memory region of size length bytes starting at location base. * * lwres_buffer_invalidate() marks the buffer *b as invalid. Invalidating * a buffer after use is not required, but makes it possible to catch its * possible accidental use. * * The functions lwres_buffer_add() and lwres_buffer_subtract() * respectively increase and decrease the used space in buffer *b by n * bytes. lwres_buffer_add() checks for buffer overflow and * lwres_buffer_subtract() checks for underflow. These functions do not * allocate or deallocate memory. They just change the value of used. * * A buffer is re-initialised by lwres_buffer_clear(). The function sets * used , current and active to zero. * * lwres_buffer_first() makes the consumed region of buffer *p empty by * setting current to zero (the start of the buffer). * * lwres_buffer_forward() increases the consumed region of buffer *b by n * bytes, checking for overflow. Similarly, lwres_buffer_back() decreases * buffer b's consumed region by n bytes and checks for underflow. * * lwres_buffer_getuint8() reads an unsigned 8-bit integer from *b and * returns it. lwres_buffer_putuint8() writes the unsigned 8-bit integer * val to buffer *b. * * lwres_buffer_getuint16() and lwres_buffer_getuint32() are identical to * lwres_buffer_putuint8() except that they respectively read an unsigned * 16-bit or 32-bit integer in network byte order from b. Similarly, * lwres_buffer_putuint16() and lwres_buffer_putuint32() writes the * unsigned 16-bit or 32-bit integer val to buffer b, in network byte * order. * * Arbitrary amounts of data are read or written from a lightweight * resolver buffer with lwres_buffer_getmem() and lwres_buffer_putmem() * respectively. lwres_buffer_putmem() copies length bytes of memory at * base to b.

The opcode is intended * to allow a client to determine if the server is operational or not. * * There are four main functions for the no-op opcode. One render * function converts a no-op request structure -- lwres_nooprequest_t -- * to the lighweight resolver's canonical format. It is complemented by a * parse function that converts a packet in this canonical format to a * no-op request structure. Another render function converts the no-op * response structure -- lwres_noopresponse_t to the canonical format. * This is complemented by a parse function which converts a packet in * canonical format to a no-op response structure. * * These structures are defined in \link lwres.h \endlink They are shown below. * * \code * #define LWRES_OPCODE_NOOP 0x00000000U * * typedef struct { * lwres_uint16_t datalength; * unsigned char *data; * } lwres_nooprequest_t; * * typedef struct { * lwres_uint16_t datalength; * unsigned char *data; * } lwres_noopresponse_t; * \endcode * * Although the structures have different types, they are identical. This * is because the no-op opcode simply echos whatever data was sent: the * response is therefore identical to the request. * * lwres_nooprequest_render() uses resolver context ctx to convert no-op * request structure req to canonical format. The packet header structure * pkt is initialised and transferred to buffer b. The contents of *req * are then appended to the buffer in canonical format. * lwres_noopresponse_render() performs the same task, except it converts * a no-op response structure lwres_noopresponse_t to the lightweight * resolver's canonical format. * * lwres_nooprequest_parse() uses context ctx to convert the contents of * packet pkt to a lwres_nooprequest_t structure. Buffer b provides space * to be used for storing this structure. When the function succeeds, the * resulting lwres_nooprequest_t is made available through *structp. * lwres_noopresponse_parse() offers the same semantics as * lwres_nooprequest_parse() except it yields a lwres_noopresponse_t * structure. * * lwres_noopresponse_free() and lwres_nooprequest_free() release the * memory in resolver context ctx that was allocated to the * lwres_noopresponse_t or lwres_nooprequest_t structures referenced via * structp. * * \section lwres_noop_return Return Values * * The no-op opcode functions lwres_nooprequest_render(), * lwres_noopresponse_render() lwres_nooprequest_parse() and * lwres_noopresponse_parse() all return #LWRES_R_SUCCESS on success.

    Synopsis

    #include <lwres/lwres.h>

    DESCRIPTION

    The BIND 9 lightweight resolver library is a simple, name service independent stub resolver library. It provides hostname-to-address and address-to-hostname lookup services to applications by transmitting lookup requests to a resolver daemon lwresd running on the local host. The resover daemon performs the lookup using the DNS or possibly other name service protocols, and returns the results to the application through the library. The library and resolver daemon communicate using a simple UDP-based protocol.

    OVERVIEW

    The lwresd library implements multiple name service APIs. The standard gethostbyname(), gethostbyaddr(), gethostbyname_r(), gethostbyaddr_r(), getaddrinfo(), getipnodebyname(), and getipnodebyaddr() functions are all supported. To allow the lwres library to coexist with system libraries that define functions of the same name, the library defines these functions with names prefixed by lwres_. To define the standard names, applications must include the header file <lwres/netdb.h> which contains macro definitions mapping the standard function names into lwres_ prefixed ones. Operating system vendors who integrate the lwres library into their base distributions should rename the functions in the library proper so that the renaming macros are not needed.

    The library also provides a native API consisting of the functions lwres_getaddrsbyname() and lwres_getnamebyaddr(). These may be called by applications that require more detailed control over the lookup process than the standard functions provide.

    In addition to these name service independent address lookup functions, the library implements a new, experimental API for looking up arbitrary DNS resource records, using the lwres_getaddrsbyname() function.

    Finally, there is a low-level API for converting lookup requests and responses to and from raw lwres protocol packets. This API can be used by clients requiring nonblocking operation, and is also used when implementing the server side of the lwres protocol, for example in the lwresd resolver daemon. The use of this low-level API in clients and servers is outlined in the following sections.

    CLIENT-SIDE LOW-LEVEL API CALL FLOW

    When a client program wishes to make an lwres request using the native low-level API, it typically performs the following sequence of actions.

    (1) Allocate or use an existing lwres_packet_t, called pkt below.

    (2) Set pkt.recvlength to the maximum length we will accept. This is done so the receiver of our packets knows how large our receive buffer is. The "default" is a constant in lwres.h: LWRES_RECVLENGTH = 4096.

    (3) Set pkt.serial to a unique serial number. This value is echoed back to the application by the remote server.

    (4) Set pkt.pktflags. Usually this is set to 0.

    (5) Set pkt.result to 0.

    (6) Call lwres_*request_render(), or marshall in the data using the primitives such as lwres_packet_render() and storing the packet data.

    (7) Transmit the resulting buffer.

    (8) Call lwres_*response_parse() to parse any packets received.

    (9) Verify that the opcode and serial match a request, and process the packet specific information contained in the body.

    SERVER-SIDE LOW-LEVEL API CALL FLOW

    When implementing the server side of the lightweight resolver protocol using the lwres library, a sequence of actions like the following is typically involved in processing each request packet.

    Note that the same lwres_packet_t is used in both the _parse() and _render() calls, with only a few modifications made to the packet header's contents between uses. This method is recommended as it keeps the serial, opcode, and other fields correct.

    (1) When a packet is received, call lwres_*request_parse() to unmarshall it. This returns a lwres_packet_t (also called pkt, below) as well as a data specific type, such as lwres_gabnrequest_t.

    (2) Process the request in the data specific type.

    (3) Set the pkt.result, pkt.recvlength as above. All other fields can be left untouched since they were filled in by the *_parse() call above. If using lwres_*response_render(), pkt.pktflags will be set up properly. Otherwise, the LWRES_LWPACKETFLAG_RESPONSE bit should be set.

    (4) Call the data specific rendering function, such as lwres_gabnresponse_render().

    (5) Send the resulting packet to the client.

    DESCRIPTION

    These functions provide bounds checked access to a region of memory where data is being read or written. They are based on, and similar to, the isc_buffer_ functions in the ISC library.

    A buffer is a region of memory, together with a set of related subregions. The used region and the available region are disjoint, and their union is the buffer's region. The used region extends from the beginning of the buffer region to the last used byte. The available region extends from one byte greater than the last used byte to the end of the buffer's region. The size of the used region can be changed using various buffer commands. Initially, the used region is empty.

    The used region is further subdivided into two disjoint regions: the consumed region and the remaining region. The union of these two regions is the used region. The consumed region extends from the beginning of the used region to the byte before the current offset (if any). The remaining region the current pointer to the end of the used region. The size of the consumed region can be changed using various buffer commands. Initially, the consumed region is empty.

    The active region is an (optional) subregion of the remaining region. It extends from the current offset to an offset in the remaining region. Initially, the active region is empty. If the current offset advances beyond the chosen offset, the active region will also be empty.

      a == base of buffer.
  b == current pointer.  Can be anywhere between a and d.
  c == active pointer.  Meaningful between b and d.
  d == used pointer.
  e == length of buffer.
      

      a-e == entire length of buffer.
  a-d == used region.
  a-b == consumed region.
  b-d == remaining region.
  b-c == optional active region.

    lwres_buffer_init() initializes the lwres_buffer_t *b and assocates it with the memory region of size length bytes starting at location base.

    lwres_buffer_invalidate() marks the buffer *b as invalid. Invalidating a buffer after use is not required, but makes it possible to catch its possible accidental use.

    The functions lwres_buffer_add() and lwres_buffer_subtract() respectively increase and decrease the used space in buffer *b by n bytes. lwres_buffer_add() checks for buffer overflow and lwres_buffer_subtract() checks for underflow. These functions do not allocate or deallocate memory. They just change the value of used.

    A buffer is re-initialised by lwres_buffer_clear(). The function sets used, current and active to zero.

    lwres_buffer_first makes the consumed region of buffer *p empty by setting current to zero (the start of the buffer).

    lwres_buffer_forward() increases the consumed region of buffer *b by n bytes, checking for overflow. Similarly, lwres_buffer_back() decreases buffer b's consumed region by n bytes and checks for underflow.

    lwres_buffer_getuint8() reads an unsigned 8-bit integer from *b and returns it. lwres_buffer_putuint8() writes the unsigned 8-bit integer val to buffer *b.

    lwres_buffer_getuint16() and lwres_buffer_getuint32() are identical to lwres_buffer_putuint8() except that they respectively read an unsigned 16-bit or 32-bit integer in network byte order from b. Similarly, lwres_buffer_putuint16() and lwres_buffer_putuint32() writes the unsigned 16-bit or 32-bit integer val to buffer b, in network byte order.

    Arbitrary amounts of data are read or written from a lightweight resolver buffer with lwres_buffer_getmem() and lwres_buffer_putmem() respectively. lwres_buffer_putmem() copies length bytes of memory at base to b. Conversely, lwres_buffer_getmem() copies length bytes of memory from b to base.

    lwres_conf_parse() opens the file filename and parses it to initialise the resolver context ctx's lwres_conf_t structure.

    lwres_conf_print() prints the lwres_conf_t structure for resolver context ctx to the FILE fp.

    RETURN VALUES

    lwres_conf_parse() returns LWRES_R_SUCCESS if it successfully read and parsed filename. It returns LWRES_R_FAILURE if filename could not be opened or contained incorrect resolver statements.

    lwres_conf_print() returns LWRES_R_SUCCESS unless an error occurred when converting the network addresses to a numeric host address string. If this happens, the function returns LWRES_R_FAILURE.

    DESCRIPTION

    lwres_context_create() creates a lwres_context_t structure for use in lightweight resolver operations. It holds a socket and other data needed for communicating with a resolver daemon. The new lwres_context_t is returned through contextp, a pointer to a lwres_context_t pointer. This lwres_context_t pointer must initially be NULL, and is modified to point to the newly created lwres_context_t.

    When the lightweight resolver needs to perform dynamic memory allocation, it will call malloc_function to allocate memory and free_function to free it. If malloc_function and free_function are NULL, memory is allocated using malloc(3). and free(3). It is not permitted to have a NULL malloc_function and a non-NULL free_function or vice versa. arg is passed as the first parameter to the memory allocation functions. If malloc_function and free_function are NULL, arg is unused and should be passed as NULL.

    Once memory for the structure has been allocated, it is initialized using lwres_conf_init(3) and returned via *contextp.

    lwres_context_destroy() destroys a lwres_context_t, closing its socket. contextp is a pointer to a pointer to the context that is to be destroyed. The pointer will be set to NULL when the context has been destroyed.

    The context holds a serial number that is used to identify resolver request packets and associate responses with the corresponding requests. This serial number is controlled using lwres_context_initserial() and lwres_context_nextserial(). lwres_context_initserial() sets the serial number for context *ctx to serial. lwres_context_nextserial() increments the serial number and returns the previous value.

    Memory for a lightweight resolver context is allocated and freed using lwres_context_allocmem() and lwres_context_freemem(). These use whatever allocations were defined when the context was created with lwres_context_create(). lwres_context_allocmem() allocates len bytes of memory and if successful returns a pointer to the allocated storage. lwres_context_freemem() frees len bytes of space starting at location mem.

    lwres_context_sendrecv() performs I/O for the context ctx. Data are read and written from the context's socket. It writes data from sendbase — typically a lightweight resolver query packet — and waits for a reply which is copied to the receive buffer at recvbase. The number of bytes that were written to this receive buffer is returned in *recvd_len.

    RETURN VALUES

    lwres_context_create() returns LWRES_R_NOMEMORY if memory for the struct lwres_context could not be allocated, LWRES_R_SUCCESS otherwise.

    Successful calls to the memory allocator lwres_context_allocmem() return a pointer to the start of the allocated space. It returns NULL if memory could not be allocated.

    LWRES_R_SUCCESS is returned when lwres_context_sendrecv() completes successfully. LWRES_R_IOERROR is returned if an I/O error occurs and LWRES_R_TIMEOUT is returned if lwres_context_sendrecv() times out waiting for a response.

There are four main functions for the getaddrbyname opcode. One render function converts a getaddrbyname request structure — lwres_gabnrequest_t — to the lighweight resolver's canonical format. It is complemented by a parse function that converts a packet in this canonical format to a getaddrbyname request structure. Another render function converts the getaddrbyname response structure — lwres_gabnresponse_t — to the canonical format. This is complemented by a parse function which converts a packet in canonical format to a getaddrbyname response structure. These structures are defined in <lwres/lwres.h>. They are shown below. #define LWRES_OPCODE_GETADDRSBYNAME 0x00010001U typedef struct lwres_addr lwres_addr_t; typedef LWRES_LIST(lwres_addr_t) lwres_addrlist_t; typedef struct { lwres_uint32_t flags; lwres_uint32_t addrtypes; lwres_uint16_t namelen; char *name; } lwres_gabnrequest_t; typedef struct { lwres_uint32_t flags; lwres_uint16_t naliases; lwres_uint16_t naddrs; char *realname; char **aliases; lwres_uint16_t realnamelen; lwres_uint16_t *aliaslen; lwres_addrlist_t addrs; void *base; size_t baselen; } lwres_gabnresponse_t; lwres_gabnrequest_render() uses resolver context ctx to convert getaddrbyname request structure req to canonical format. The packet header structure pkt is initialised and transferred to buffer b. The contents of *req are then appended to the buffer in canonical format. lwres_gabnresponse_render() performs the same task, except it converts a getaddrbyname response structure lwres_gabnresponse_t to the lightweight resolver's canonical format. lwres_gabnrequest_parse() uses context ctx to convert the contents of packet pkt to a lwres_gabnrequest_t structure. Buffer b provides space to be used for storing this structure. When the function succeeds, the resulting lwres_gabnrequest_t is made available through *structp. lwres_gabnresponse_parse() offers the same semantics as lwres_gabnrequest_parse() except it yields a lwres_gabnresponse_t structure. lwres_gabnresponse_free() and lwres_gabnrequest_free() release the memory in resolver context ctx that was allocated to the lwres_gabnresponse_t or lwres_gabnrequest_t structures referenced via structp. Any memory associated with ancillary buffers and strings for those structures is also discarded. RETURN VALUES The getaddrbyname opcode functions lwres_gabnrequest_render(), lwres_gabnresponse_render() lwres_gabnrequest_parse() and lwres_gabnresponse_parse() all return LWRES_R_SUCCESS on success. They return LWRES_R_NOMEMORY if memory allocation fails.

    DESCRIPTION

    These are low-level routines for creating and parsing lightweight resolver name-to-address lookup request and response messages.

    There are four main functions for the getaddrbyname opcode. One render function converts a getaddrbyname request structure — lwres_gabnrequest_t — to the lighweight resolver's canonical format. It is complemented by a parse function that converts a packet in this canonical format to a getaddrbyname request structure. Another render function converts the getaddrbyname response structure — lwres_gabnresponse_t — to the canonical format. This is complemented by a parse function which converts a packet in canonical format to a getaddrbyname response structure.

    These structures are defined in <lwres/lwres.h>. They are shown below. 

    #define LWRES_OPCODE_GETADDRSBYNAME     0x00010001U


    typedef struct lwres_addr lwres_addr_t;
typedef LWRES_LIST(lwres_addr_t) lwres_addrlist_t;


    typedef struct {
        lwres_uint32_t  flags;
        lwres_uint32_t  addrtypes;
        lwres_uint16_t  namelen;
        char           *name;
} lwres_gabnrequest_t;


    typedef struct {
        lwres_uint32_t          flags;
        lwres_uint16_t          naliases;
        lwres_uint16_t          naddrs;
        char                   *realname;
        char                  **aliases;
        lwres_uint16_t          realnamelen;
        lwres_uint16_t         *aliaslen;
        lwres_addrlist_t        addrs;
        void                   *base;
        size_t                  baselen;
} lwres_gabnresponse_t;

    lwres_gabnrequest_render() uses resolver context ctx to convert getaddrbyname request structure req to canonical format. The packet header structure pkt is initialised and transferred to buffer b. The contents of *req are then appended to the buffer in canonical format. lwres_gabnresponse_render() performs the same task, except it converts a getaddrbyname response structure lwres_gabnresponse_t to the lightweight resolver's canonical format.

    lwres_gabnrequest_parse() uses context ctx to convert the contents of packet pkt to a lwres_gabnrequest_t structure. Buffer b provides space to be used for storing this structure. When the function succeeds, the resulting lwres_gabnrequest_t is made available through *structp. lwres_gabnresponse_parse() offers the same semantics as lwres_gabnrequest_parse() except it yields a lwres_gabnresponse_t structure.

    lwres_gabnresponse_free() and lwres_gabnrequest_free() release the memory in resolver context ctx that was allocated to the lwres_gabnresponse_t or lwres_gabnrequest_t structures referenced via structp. Any memory associated with ancillary buffers and strings for those structures is also discarded.

    RETURN VALUES

    The getaddrbyname opcode functions lwres_gabnrequest_render(), lwres_gabnresponse_render() lwres_gabnrequest_parse() and lwres_gabnresponse_parse() all return LWRES_R_SUCCESS on success. They return LWRES_R_NOMEMORY if memory allocation fails. LWRES_R_UNEXPECTEDEND is returned if the available space in the buffer b is too small to accommodate the packet header or the lwres_gabnrequest_t and lwres_gabnresponse_t structures. lwres_gabnrequest_parse() and lwres_gabnresponse_parse() will return LWRES_R_UNEXPECTEDEND if the buffer is not empty after decoding the received packet. These functions will return LWRES_R_FAILURE if pktflags in the packet header structure lwres_lwpacket_t indicate that the packet is not a response to an earlier query.

This structure can be used to provide hints concerning the type of socket that the caller supports or wishes to use. The caller can supply the following structure elements in *hints: ai_family The protocol family that should be used. When ai_family is set to PF_UNSPEC, it means the caller will accept any protocol family supported by the operating system. ai_socktype denotes the type of socket — SOCK_STREAM, SOCK_DGRAM or SOCK_RAW — that is wanted. When ai_socktype is zero the caller will accept any socket type. ai_protocol indicates which transport protocol is wanted: IPPROTO_UDP or IPPROTO_TCP. If ai_protocol is zero the caller will accept any protocol. ai_flags Flag bits. If the AI_CANONNAME bit is set, a successful call to lwres_getaddrinfo() will return a null-terminated string containing the canonical name of the specified hostname in ai_canonname of the first addrinfo structure returned. Setting the AI_PASSIVE bit indicates that the returned socket address structure is intended for used in a call to bind2 . In this case, if the hostname argument is a NULL pointer, then the IP address portion of the socket address structure will be set to INADDR_ANY for an IPv4 address or IN6ADDR_ANY_INIT for an IPv6 address.

The IP address portion of the socket address structure will be set to the loopback address if hostname is a NULL pointer and AI_PASSIVE is not set in ai_flags. If ai_flags is set to AI_NUMERICHOST it indicates that hostname should be treated as a numeric string defining an IPv4 or IPv6 address and no name resolution should be attempted. All other elements of the struct addrinfo passed via hints must be zero. A hints of NULL is treated as if the caller provided a struct addrinfo initialized to zero with ai_familyset to PF_UNSPEC. After a successful call to lwres_getaddrinfo(), *res is a pointer to a linked list of one or more addrinfo structures. Each struct addrinfo in this list cn be processed by following the ai_next pointer, until a NULL pointer is encountered.

    DESCRIPTION

    lwres_getaddrinfo() is used to get a list of IP addresses and port numbers for host hostname and service servname. The function is the lightweight resolver's implementation of getaddrinfo() as defined in RFC2133. hostname and servname are pointers to null-terminated strings or NULL. hostname is either a host name or a numeric host address string: a dotted decimal IPv4 address or an IPv6 address. servname is either a decimal port number or a service name as listed in /etc/services.

    hints is an optional pointer to a struct addrinfo. This structure can be used to provide hints concerning the type of socket that the caller supports or wishes to use. The caller can supply the following structure elements in *hints:

    ai_family

    The protocol family that should be used. When ai_family is set to PF_UNSPEC, it means the caller will accept any protocol family supported by the operating system.

    ai_socktype

    denotes the type of socket — SOCK_STREAM, SOCK_DGRAM or SOCK_RAW — that is wanted. When ai_socktype is zero the caller will accept any socket type.

    ai_protocol

    indicates which transport protocol is wanted: IPPROTO_UDP or IPPROTO_TCP. If ai_protocol is zero the caller will accept any protocol.

    ai_flags

    Flag bits. If the AI_CANONNAME bit is set, a successful call to lwres_getaddrinfo() will return a null-terminated string containing the canonical name of the specified hostname in ai_canonname of the first addrinfo structure returned. Setting the AI_PASSIVE bit indicates that the returned socket address structure is intended for used in a call to bind(2). In this case, if the hostname argument is a NULL pointer, then the IP address portion of the socket address structure will be set to INADDR_ANY for an IPv4 address or IN6ADDR_ANY_INIT for an IPv6 address.

    When ai_flags does not set the AI_PASSIVE bit, the returned socket address structure will be ready for use in a call to connect(2) for a connection-oriented protocol or connect(2), sendto(2), or sendmsg(2) if a connectionless protocol was chosen. The IP address portion of the socket address structure will be set to the loopback address if hostname is a NULL pointer and AI_PASSIVE is not set in ai_flags.

    If ai_flags is set to AI_NUMERICHOST it indicates that hostname should be treated as a numeric string defining an IPv4 or IPv6 address and no name resolution should be attempted.

    All other elements of the struct addrinfo passed via hints must be zero.

    A hints of NULL is treated as if the caller provided a struct addrinfo initialized to zero with ai_familyset to PF_UNSPEC.

    After a successful call to lwres_getaddrinfo(), *res is a pointer to a linked list of one or more addrinfo structures. Each struct addrinfo in this list cn be processed by following the ai_next pointer, until a NULL pointer is encountered. The three members ai_family, ai_socktype, and ai_protocol in each returned addrinfo structure contain the corresponding arguments for a call to socket(2). For each addrinfo structure in the list, the ai_addr member points to a filled-in socket address structure of length ai_addrlen.

    All of the information returned by lwres_getaddrinfo() is dynamically allocated: the addrinfo structures, and the socket address structures and canonical host name strings pointed to by the addrinfostructures. Memory allocated for the dynamically allocated structures created by a successful call to lwres_getaddrinfo() is released by lwres_freeaddrinfo(). ai is a pointer to a struct addrinfo created by a call to lwres_getaddrinfo().

    RETURN VALUES

    lwres_getaddrinfo() returns zero on success or one of the error codes listed in gai_strerror(3) if an error occurs. If both hostname and servname are NULL lwres_getaddrinfo() returns EAI_NONAME.

    DESCRIPTION

    These functions provide hostname-to-address and address-to-hostname lookups by means of the lightweight resolver. They are similar to the standard gethostent(3) functions provided by most operating systems. They use a struct hostent which is usually defined in <namedb.h>. 

    struct  hostent {
        char    *h_name;        /* official name of host */
        char    **h_aliases;    /* alias list */
        int     h_addrtype;     /* host address type */
        int     h_length;       /* length of address */
        char    **h_addr_list;  /* list of addresses from name server */
};
#define h_addr  h_addr_list[0]  /* address, for backward compatibility */

    The members of this structure are:

    h_name

    The official (canonical) name of the host.

    h_aliases

    A NULL-terminated array of alternate names (nicknames) for the host.

    h_addrtype

    The type of address being returned — PF_INET or PF_INET6.

    h_length

    The length of the address in bytes.

    h_addr_list

    A NULL terminated array of network addresses for the host. Host addresses are returned in network byte order.

    For backward compatibility with very old software, h_addr is the first address in h_addr_list.

    lwres_gethostent(), lwres_sethostent(), lwres_endhostent(), lwres_gethostent_r(), lwres_sethostent_r() and lwres_endhostent_r() provide iteration over the known host entries on systems that provide such functionality through facilities like /etc/hosts or NIS. The lightweight resolver does not currently implement these functions; it only provides them as stub functions that always return failure.

    lwres_gethostbyname() and lwres_gethostbyname2() look up the hostname name. lwres_gethostbyname() always looks for an IPv4 address while lwres_gethostbyname2() looks for an address of protocol family af: either PF_INET or PF_INET6 — IPv4 or IPV6 addresses respectively. Successful calls of the functions return a struct hostentfor the name that was looked up. NULL is returned if the lookups by lwres_gethostbyname() or lwres_gethostbyname2() fail.

    Reverse lookups of addresses are performed by lwres_gethostbyaddr(). addr is an address of length len bytes and protocol family type — PF_INET or PF_INET6. lwres_gethostbyname_r() is a thread-safe function for forward lookups. If an error occurs, an error code is returned in *error. resbuf is a pointer to a struct hostent which is initialised by a successful call to lwres_gethostbyname_r(). buf is a buffer of length len bytes which is used to store the h_name, h_aliases, and h_addr_list elements of the struct hostent returned in resbuf. Successful calls to lwres_gethostbyname_r() return resbuf, which is a pointer to the struct hostent it created.

    lwres_gethostbyaddr_r() is a thread-safe function that performs a reverse lookup of address addr which is len bytes long and is of protocol family type — PF_INET or PF_INET6. If an error occurs, the error code is returned in *error. The other function parameters are identical to those in lwres_gethostbyname_r(). resbuf is a pointer to a struct hostent which is initialised by a successful call to lwres_gethostbyaddr_r(). buf is a buffer of length len bytes which is used to store the h_name, h_aliases, and h_addr_list elements of the struct hostent returned in resbuf. Successful calls to lwres_gethostbyaddr_r() return resbuf, which is a pointer to the struct hostent() it created.

    RETURN VALUES

    The functions lwres_gethostbyname(), lwres_gethostbyname2(), lwres_gethostbyaddr(), and lwres_gethostent() return NULL to indicate an error. In this case the global variable lwres_h_errno will contain one of the following error codes defined in <lwres/netdb.h>:

    HOST_NOT_FOUND

    The host or address was not found.

    TRY_AGAIN

    A recoverable error occurred, e.g., a timeout. Retrying the lookup may succeed.

    NO_RECOVERY

    A non-recoverable error occurred.

    NO_DATA

    The name exists, but has no address information associated with it (or vice versa in the case of a reverse lookup). The code NO_ADDRESS is accepted as a synonym for NO_DATA for backwards compatibility.

    lwres_hstrerror(3) translates these error codes to suitable error messages.

    lwres_gethostent() and lwres_gethostent_r() always return NULL.

    Successful calls to lwres_gethostbyname_r() and lwres_gethostbyaddr_r() return resbuf, a pointer to the struct hostent that was initialised by these functions. They return NULL if the lookups fail or if buf was too small to hold the list of addresses and names referenced by the h_name, h_aliases, and h_addr_list elements of the struct hostent. If buf was too small, both lwres_gethostbyname_r() and lwres_gethostbyaddr_r() set the global variable errno to ERANGE.

    BUGS

    lwres_gethostbyname(), lwres_gethostbyname2(), lwres_gethostbyaddr() and lwres_endhostent() are not thread safe; they return pointers to static data and provide error codes through a global variable. Thread-safe versions for name and address lookup are provided by lwres_gethostbyname_r(), and lwres_gethostbyaddr_r() respectively.

    The resolver daemon does not currently support any non-DNS name services such as /etc/hosts or NIS, consequently the above functions don't, either.

    Synopsis

    #include <lwres/netdb.h>
    struct hostent * lwres_getipnodebyname( const char *  name,
      int   af,
      int   flags,
      int *  error_num);

    DESCRIPTION

    These functions perform thread safe, protocol independent nodename-to-address and address-to-nodename translation as defined in RFC2553.

    They use a struct hostent which is defined in namedb.h: 

    struct  hostent {
        char    *h_name;        /* official name of host */
        char    **h_aliases;    /* alias list */
        int     h_addrtype;     /* host address type */
        int     h_length;       /* length of address */
        char    **h_addr_list;  /* list of addresses from name server */
};
#define h_addr  h_addr_list[0]  /* address, for backward compatibility */

    The members of this structure are:

    h_name

    The official (canonical) name of the host.

    h_aliases

    A NULL-terminated array of alternate names (nicknames) for the host.

    h_addrtype

    The type of address being returned - usually PF_INET or PF_INET6.

    h_length

    The length of the address in bytes.

    h_addr_list

    A NULL terminated array of network addresses for the host. Host addresses are returned in network byte order.

    lwres_getipnodebyname() looks up addresses of protocol family af for the hostname name. The flags parameter contains ORed flag bits to specify the types of addresses that are searched for, and the types of addresses that are returned. The flag bits are:

    AI_V4MAPPED

    This is used with an af of AF_INET6, and causes IPv4 addresses to be returned as IPv4-mapped IPv6 addresses.

    AI_ALL

    This is used with an af of AF_INET6, and causes all known addresses (IPv6 and IPv4) to be returned. If AI_V4MAPPED is also set, the IPv4 addresses are return as mapped IPv6 addresses.

    AI_ADDRCONFIG

    Only return an IPv6 or IPv4 address if here is an active network interface of that type. This is not currently implemented in the BIND 9 lightweight resolver, and the flag is ignored.

    AI_DEFAULT

    This default sets the AI_V4MAPPED and AI_ADDRCONFIG flag bits.

    lwres_getipnodebyaddr() performs a reverse lookup of address src which is len bytes long. af denotes the protocol family, typically PF_INET or PF_INET6.

    lwres_freehostent() releases all the memory associated with the struct hostent pointer he. Any memory allocated for the h_name, h_addr_list and h_aliases is freed, as is the memory for the hostent structure itself.

    RETURN VALUES

    If an error occurs, lwres_getipnodebyname() and lwres_getipnodebyaddr() set *error_num to an appropriate error code and the function returns a NULL pointer. The error codes and their meanings are defined in <lwres/netdb.h>:

    HOST_NOT_FOUND

    No such host is known.

    NO_ADDRESS

    The server recognised the request and the name but no address is available. Another type of request to the name server for the domain might return an answer.

    TRY_AGAIN

    A temporary and possibly transient error occurred, such as a failure of a server to respond. The request may succeed if retried.

    NO_RECOVERY

    An unexpected failure occurred, and retrying the request is pointless.

    lwres_hstrerror(3) translates these error codes to suitable error messages.

    DESCRIPTION

    This function is equivalent to the getnameinfo(3) function defined in RFC2133. lwres_getnameinfo() returns the hostname for the struct sockaddr sa which is salen bytes long. The hostname is of length hostlen and is returned via *host. The maximum length of the hostname is 1025 bytes: NI_MAXHOST.

    The name of the service associated with the port number in sa is returned in *serv. It is servlen bytes long. The maximum length of the service name is NI_MAXSERV - 32 bytes.

    The flags argument sets the following bits:

    NI_NOFQDN

    A fully qualified domain name is not required for local hosts. The local part of the fully qualified domain name is returned instead.

    NI_NUMERICHOST

    Return the address in numeric form, as if calling inet_ntop(), instead of a host name.

    NI_NAMEREQD

    A name is required. If the hostname cannot be found in the DNS and this flag is set, a non-zero error code is returned. If the hostname is not found and the flag is not set, the address is returned in numeric form.

    NI_NUMERICSERV

    The service name is returned as a digit string representing the port number.

    NI_DGRAM

    Specifies that the service being looked up is a datagram service, and causes getservbyport() to be called with a second argument of "udp" instead of its default of "tcp". This is required for the few ports (512-514) that have different services for UDP and TCP.

    RETURN VALUES

    lwres_getnameinfo() returns 0 on success or a non-zero error code if an error occurs.

    SEE ALSO

    DESCRIPTION

    These are low-level routines for creating and parsing lightweight resolver address-to-name lookup request and response messages.

    There are four main functions for the getnamebyaddr opcode. One render function converts a getnamebyaddr request structure — lwres_gnbarequest_t — to the lightweight resolver's canonical format. It is complemented by a parse function that converts a packet in this canonical format to a getnamebyaddr request structure. Another render function converts the getnamebyaddr response structure — lwres_gnbaresponse_t to the canonical format. This is complemented by a parse function which converts a packet in canonical format to a getnamebyaddr response structure.

    These structures are defined in lwres/lwres.h. They are shown below. 

    #define LWRES_OPCODE_GETNAMEBYADDR      0x00010002U


    typedef struct {
        lwres_uint32_t  flags;
        lwres_addr_t    addr;
} lwres_gnbarequest_t;


    typedef struct {
        lwres_uint32_t  flags;
        lwres_uint16_t  naliases;
        char           *realname;
        char          **aliases;
        lwres_uint16_t  realnamelen;
        lwres_uint16_t *aliaslen;
        void           *base;
        size_t          baselen;
} lwres_gnbaresponse_t;

    lwres_gnbarequest_render() uses resolver context ctx to convert getnamebyaddr request structure req to canonical format. The packet header structure pkt is initialised and transferred to buffer b. The contents of *req are then appended to the buffer in canonical format. lwres_gnbaresponse_render() performs the same task, except it converts a getnamebyaddr response structure lwres_gnbaresponse_t to the lightweight resolver's canonical format.

    lwres_gnbarequest_parse() uses context ctx to convert the contents of packet pkt to a lwres_gnbarequest_t structure. Buffer b provides space to be used for storing this structure. When the function succeeds, the resulting lwres_gnbarequest_t is made available through *structp. lwres_gnbaresponse_parse() offers the same semantics as lwres_gnbarequest_parse() except it yields a lwres_gnbaresponse_t structure.

    lwres_gnbaresponse_free() and lwres_gnbarequest_free() release the memory in resolver context ctx that was allocated to the lwres_gnbaresponse_t or lwres_gnbarequest_t structures referenced via structp. Any memory associated with ancillary buffers and strings for those structures is also discarded.

    RETURN VALUES

    The getnamebyaddr opcode functions lwres_gnbarequest_render(), lwres_gnbaresponse_render() lwres_gnbarequest_parse() and lwres_gnbaresponse_parse() all return LWRES_R_SUCCESS on success. They return LWRES_R_NOMEMORY if memory allocation fails. LWRES_R_UNEXPECTEDEND is returned if the available space in the buffer b is too small to accommodate the packet header or the lwres_gnbarequest_t and lwres_gnbaresponse_t structures. lwres_gnbarequest_parse() and lwres_gnbaresponse_parse() will return LWRES_R_UNEXPECTEDEND if the buffer is not empty after decoding the received packet. These functions will return LWRES_R_FAILURE if pktflags in the packet header structure lwres_lwpacket_t indicate that the packet is not a response to an earlier query.

    DESCRIPTION

    These are low-level routines for creating and parsing lightweight resolver no-op request and response messages.

    The no-op message is analogous to a ping packet: a packet is sent to the resolver daemon and is simply echoed back. The opcode is intended to allow a client to determine if the server is operational or not.

    There are four main functions for the no-op opcode. One render function converts a no-op request structure — lwres_nooprequest_t — to the lighweight resolver's canonical format. It is complemented by a parse function that converts a packet in this canonical format to a no-op request structure. Another render function converts the no-op response structure — lwres_noopresponse_t to the canonical format. This is complemented by a parse function which converts a packet in canonical format to a no-op response structure.

    These structures are defined in lwres/lwres.h. They are shown below. 

    #define LWRES_OPCODE_NOOP       0x00000000U


    typedef struct {
        lwres_uint16_t  datalength;
        unsigned char   *data;
} lwres_nooprequest_t;


    typedef struct {
        lwres_uint16_t  datalength;
        unsigned char   *data;
} lwres_noopresponse_t;

    Although the structures have different types, they are identical. This is because the no-op opcode simply echos whatever data was sent: the response is therefore identical to the request.

    lwres_nooprequest_render() uses resolver context ctx to convert no-op request structure req to canonical format. The packet header structure pkt is initialised and transferred to buffer b. The contents of *req are then appended to the buffer in canonical format. lwres_noopresponse_render() performs the same task, except it converts a no-op response structure lwres_noopresponse_t to the lightweight resolver's canonical format.

    lwres_nooprequest_parse() uses context ctx to convert the contents of packet pkt to a lwres_nooprequest_t structure. Buffer b provides space to be used for storing this structure. When the function succeeds, the resulting lwres_nooprequest_t is made available through *structp. lwres_noopresponse_parse() offers the same semantics as lwres_nooprequest_parse() except it yields a lwres_noopresponse_t structure.

    lwres_noopresponse_free() and lwres_nooprequest_free() release the memory in resolver context ctx that was allocated to the lwres_noopresponse_t or lwres_nooprequest_t structures referenced via structp.

    RETURN VALUES

    The no-op opcode functions lwres_nooprequest_render(), lwres_noopresponse_render() lwres_nooprequest_parse() and lwres_noopresponse_parse() all return LWRES_R_SUCCESS on success. They return LWRES_R_NOMEMORY if memory allocation fails. LWRES_R_UNEXPECTEDEND is returned if the available space in the buffer b is too small to accommodate the packet header or the lwres_nooprequest_t and lwres_noopresponse_t structures. lwres_nooprequest_parse() and lwres_noopresponse_parse() will return LWRES_R_UNEXPECTEDEND if the buffer is not empty after decoding the received packet. These functions will return LWRES_R_FAILURE if pktflags in the packet header structure lwres_lwpacket_t indicate that the packet is not a response to an earlier query.

    DESCRIPTION

    These functions rely on a struct lwres_lwpacket which is defined in lwres/lwpacket.h. 

    typedef struct lwres_lwpacket lwres_lwpacket_t;
      

    struct lwres_lwpacket {
        lwres_uint32_t          length;
        lwres_uint16_t          version;
        lwres_uint16_t          pktflags;
        lwres_uint32_t          serial;
        lwres_uint32_t          opcode;
        lwres_uint32_t          result;
        lwres_uint32_t          recvlength;
        lwres_uint16_t          authtype;
        lwres_uint16_t          authlength;
};

    The elements of this structure are:

    length

    the overall packet length, including the entire packet header. This field is filled in by the lwres_gabn_*() and lwres_gnba_*() calls.

    version

    the header format. There is currently only one format, LWRES_LWPACKETVERSION_0. This field is filled in by the lwres_gabn_*() and lwres_gnba_*() calls.

    pktflags

    library-defined flags for this packet: for instance whether the packet is a request or a reply. Flag values can be set, but not defined by the caller. This field is filled in by the application wit the exception of the LWRES_LWPACKETFLAG_RESPONSE bit, which is set by the library in the lwres_gabn_*() and lwres_gnba_*() calls.

    serial

    is set by the requestor and is returned in all replies. If two or more packets from the same source have the same serial number and are from the same source, they are assumed to be duplicates and the latter ones may be dropped. This field must be set by the application.

    opcode

    indicates the operation. Opcodes between 0x00000000 and 0x03ffffff are reserved for use by the lightweight resolver library. Opcodes between 0x04000000 and 0xffffffff are application defined. This field is filled in by the lwres_gabn_*() and lwres_gnba_*() calls.

    result

    is only valid for replies. Results between 0x04000000 and 0xffffffff are application defined. Results between 0x00000000 and 0x03ffffff are reserved for library use. This field is filled in by the lwres_gabn_*() and lwres_gnba_*() calls.

    recvlength

    is the maximum buffer size that the receiver can handle on requests and the size of the buffer needed to satisfy a request when the buffer is too large for replies. This field is supplied by the application.

    authtype

    defines the packet level authentication that is used. Authorisation types between 0x1000 and 0xffff are application defined and types between 0x0000 and 0x0fff are reserved for library use. Currently these are not used and must be zero.

    authlen

    gives the length of the authentication data. Since packet authentication is currently not used, this must be zero.

    The following opcodes are currently defined:

    NOOP

    Success is always returned and the packet contents are echoed. The lwres_noop_*() functions should be used for this type.

    GETADDRSBYNAME

    returns all known addresses for a given name. The lwres_gabn_*() functions should be used for this type.

    GETNAMEBYADDR

    return the hostname for the given address. The lwres_gnba_*() functions should be used for this type.

    lwres_lwpacket_renderheader() transfers the contents of lightweight resolver packet structure lwres_lwpacket_t *pkt in network byte order to the lightweight resolver buffer, *b.

    lwres_lwpacket_parseheader() performs the converse operation. It transfers data in network byte order from buffer *b to resolver packet *pkt. The contents of the buffer b should correspond to a lwres_lwpacket_t.

    RETURN VALUES

    Successful calls to lwres_lwpacket_renderheader() and lwres_lwpacket_parseheader() return LWRES_R_SUCCESS. If there is insufficient space to copy data between the buffer *b and lightweight resolver packet *pkt both functions return LWRES_R_UNEXPECTEDEND.

    DESCRIPTION

    lwres_string_parse() retrieves a DNS-encoded string starting the current pointer of lightweight resolver buffer b: i.e. b->current. When the function returns, the address of the first byte of the encoded string is returned via *c and the length of that string is given by *len. The buffer's current pointer is advanced to point at the character following the string length, the encoded string, and the trailing NULL character.

    lwres_addr_parse() extracts an address from the buffer b. The buffer's current pointer b->current is presumed to point at an encoded address: the address preceded by a 32-bit protocol family identifier and a 16-bit length field. The encoded address is copied to addr->address and addr->length indicates the size in bytes of the address that was copied. b->current is advanced to point at the next byte of available data in the buffer following the encoded address.

    lwres_getaddrsbyname() and lwres_getnamebyaddr() use the lwres_gnbaresponse_t structure defined below: 

    typedef struct {
        lwres_uint32_t          flags;
        lwres_uint16_t          naliases;
        lwres_uint16_t          naddrs;
        char                   *realname;
        char                  **aliases;
        lwres_uint16_t          realnamelen;
        lwres_uint16_t         *aliaslen;
        lwres_addrlist_t        addrs;
        void                   *base;
        size_t                  baselen;
} lwres_gabnresponse_t;

    The contents of this structure are not manipulated directly but they are controlled through the lwres_gabn(3) functions.

    The lightweight resolver uses lwres_getaddrsbyname() to perform foward lookups. Hostname name is looked up using the resolver context ctx for memory allocation. addrtypes is a bitmask indicating which type of addresses are to be looked up. Current values for this bitmask are LWRES_ADDRTYPE_V4 for IPv4 addresses and LWRES_ADDRTYPE_V6 for IPv6 addresses. Results of the lookup are returned in *structp.

    lwres_getnamebyaddr() performs reverse lookups. Resolver context ctx is used for memory allocation. The address type is indicated by addrtype: LWRES_ADDRTYPE_V4 or LWRES_ADDRTYPE_V6. The address to be looked up is given by addr and its length is addrlen bytes. The result of the function call is made available through *structp.

    RETURN VALUES

    Successful calls to lwres_string_parse() and lwres_addr_parse() return LWRES_R_SUCCESS. Both functions return LWRES_R_FAILURE if the buffer is corrupt or LWRES_R_UNEXPECTEDEND if the buffer has less space than expected for the components of the encoded string or address.

    lwres_getaddrsbyname() returns LWRES_R_SUCCESS on success and it returns LWRES_R_NOTFOUND if the hostname name could not be found.

    LWRES_R_SUCCESS is returned by a successful call to lwres_getnamebyaddr().

    Both lwres_getaddrsbyname() and lwres_getnamebyaddr() return LWRES_R_NOMEMORY when memory allocation requests fail and LWRES_R_UNEXPECTEDEND if the buffers used for sending queries and receiving replies are too small.

The * undefine action (if provided) will be called * with the old tuple. *\li isccc_symexists_add Add the new tuple, leaving the old tuple in * the table. Subsequent lookups will retrieve * the most-recently-defined tuple. * * A lookup of a key using type 0 will return the most-recently * defined symbol with that key. An undefine of a key using type 0 * will undefine the most-recently defined symbol with that key. * Trying to define a key with type 0 is illegal. * * The symbol table library does not make a copy the key field, so the * caller must ensure that any key it passes to isccc_symtab_define() * will not change until it calls isccc_symtab_undefine() or * isccc_symtab_destroy(). * * A user-specified action will be called (if provided) when a symbol * is undefined.

Both variables begin with the initial * value of 0. When a new writer tries to get a write lock, it increments * write_requests and gets the previous value of the variable as a "ticket". * When write_completions reaches the ticket number, the new writer can start * writing. When the writer completes its work, it increments * write_completions so that another new writer can start working. If the * write_requests is not equal to write_completions, it means a writer is now * working or waiting. In this case, a new readers cannot start reading, or * in other words, this algorithm basically prefers writers. * * cnt_and_flag is a "lock" shared by all readers and writers. This integer * variable is a kind of structure with two members: writer_flag (1 bit) and * reader_count (31 bits). The writer_flag shows whether a writer is working, * and the reader_count shows the number of readers currently working or almost * ready for working. A writer who has the current "ticket" tries to get the * lock by exclusively setting the writer_flag to 1, provided that the whole * 32-bit is 0 (meaning no readers or writers working). On the other hand, * a new reader tries to increment the "reader_count" field provided that * the writer_flag is 0 (meaning there is no writer working). * * If some of the above operations fail, the reader or the writer sleeps * until the related condition changes. When a working reader or writer * completes its work, some readers or writers are sleeping, and the condition * that suspended the reader or writer has changed, it wakes up the sleeping * readers or writers. * * As already noted, this algorithm basically prefers writers. In order to * prevent readers from starving, however, the algorithm also introduces the * "writer quota" (Q). When Q consecutive writers have completed their work, * suspending readers, the last writer will wake up the readers, even if a new * writer is waiting. * * Implementation specific note: due to the combination of atomic operations * and a mutex lock, ordering between the atomic operation and locks can be * very sensitive in some cases. In particular, it is generally very important * to check the atomic variable that requires a reader or writer to sleep after * locking the mutex and before actually sleeping; otherwise, it could be very * likely to cause a deadlock. For example, assume "var" is a variable * atomically modified, then the corresponding code would be: * if (var == need_sleep) { * LOCK(lock); * if (var == need_sleep) * WAIT(cond, lock); * UNLOCK(lock); * } * The second check is important, since "var" is protected by the atomic * operation, not by the mutex, and can be changed just before sleeping. * (The first "if" could be omitted, but this is also important in order to * make the code efficient by avoiding the use of the mutex unless it is * really necessary.) */ #define WRITER_ACTIVE 0x1 #define READER_INCR 0x2 isc_result_t isc_rwlock_lock(isc_rwlock_t *rwl, isc_rwlocktype_t type) { isc_int32_t cntflag; REQUIRE(VALID_RWLOCK(rwl)); #ifdef ISC_RWLOCK_TRACE print_lock(isc_msgcat_get(isc_msgcat, ISC_MSGSET_RWLOCK, ISC_MSG_PRELOCK, "prelock"), rwl, type); #endif if (type == isc_rwlocktype_read) { if (rwl->write_requests != rwl->write_completions) { /* there is a waiting or active writer */ LOCK(&rwl->lock); if (rwl->write_requests != rwl->write_completions) { rwl->readers_waiting++; WAIT(&rwl->readable, &rwl->lock); rwl->readers_waiting--; } UNLOCK(&rwl->lock); } cntflag = isc_atomic_xadd(&rwl->cnt_and_flag, READER_INCR); POST(cntflag); while (1) { if ((rwl->cnt_and_flag & WRITER_ACTIVE) == 0) break; /* A writer is still working */ LOCK(&rwl->lock); rwl->readers_waiting++; if ((rwl->cnt_and_flag & WRITER_ACTIVE) != 0) WAIT(&rwl->readable, &rwl->lock); rwl->readers_waiting--; UNLOCK(&rwl->lock); /* * Typically, the reader should be able to get a lock * at this stage: * (1) there should have been no pending writer when * the reader was trying to increment the * counter; otherwise, the writer should be in * the waiting queue, preventing the reader from * proceeding to this point. * (2) once the reader increments the counter, no * more writer can get a lock. * Still, it is possible another writer can work at * this point, e.g. in the following scenario: * A previous writer unlocks the writer lock. * This reader proceeds to point (1). * A new writer appears, and gets a new lock before * the reader increments the counter. * The reader then increments the counter. * The previous writer notices there is a waiting * reader who is almost ready, and wakes it up. * So, the reader needs to confirm whether it can now * read explicitly (thus we loop).

This is also due to not yet really needing all * of the functionality of an NT system (or, for that matter, a POSIX system) * in BIND9, and so resolving how to handle the various incompatibilities has * been a purely theoretical exercise with no operational experience to * indicate how flawed the thinking may be. * * Some of the more notable dumbing down of NT for this API includes: * *\li Each of FILE_READ_DATA and FILE_READ_EA are set with #ISC_FSACCESS_READ. * * \li All of FILE_WRITE_DATA, FILE_WRITE_EA and FILE_APPEND_DATA are * set with #ISC_FSACCESS_WRITE. FILE_WRITE_ATTRIBUTES is not set * so as to be consistent with Unix, where only the owner of the file * or the superuser can change the attributes/mode of a file. * * \li Both of FILE_ADD_FILE and FILE_ADD_SUBDIRECTORY are set with * #ISC_FSACCESS_CREATECHILD. This is similar to setting the WRITE * permission on a Unix directory. * * \li SYNCHRONIZE is always set for files and directories, unless someone * can give me a reason why this is a bad idea. * * \li READ_CONTROL and FILE_READ_ATTRIBUTES are always set; this is * consistent with Unix, where any file or directory can be stat()'d * unless the directory path disallows complete access somewhere along * the way. * * \li WRITE_DAC is only set for the owner. This too is consistent with * Unix, and is tighter security than allowing anyone else to be * able to set permissions. * * \li DELETE is only set for the owner. On Unix the ability to delete * a file is controlled by the directory permissions, but it isn't * currently clear to me what happens on NT if the directory has * FILE_DELETE_CHILD set but a file within it does not have DELETE * set. Always setting DELETE on the file/directory for the owner * gives maximum flexibility to the owner without exposing the * file to deletion by others. * * \li WRITE_OWNER is never set. This too is consistent with Unix, * and is also tighter security than allowing anyone to change the * ownership of the file apart from the superu..ahem, Administrator. * * \li Inheritance is set to NO_INHERITANCE. * * Unix's dumbing down includes: * * \li The sticky bit cannot be set. * * \li setuid and setgid cannot be set. * * \li Only regular files and directories can be set. * * The rest of this comment discusses a few of the incompatibilities * between the two systems that need more thought if this API is to * be extended to accommodate them. * * The Windows standard access right "DELETE" doesn't have a direct * equivalent in the Unix world, so it isn't clear what should be done * with it. * * The Unix sticky bit is not supported. While NT does have a concept * of allowing users to create files in a directory but not delete or * rename them, it does not have a concept of allowing them to be deleted * if they are owned by the user trying to delete/rename. While it is * probable that something could be cobbled together in NT 5 with inheritance, * it can't really be done in NT 4 as a single property that you could * set on a directory. You'd need to coordinate something with file creation * so that every file created had DELETE set for the owner but noone else. * * On Unix systems, setting #ISC_FSACCESS_LISTDIRECTORY sets READ. * ... setting either #ISC_FSACCESS_CREATECHILD or #ISC_FSACCESS_DELETECHILD * sets WRITE. * ... setting #ISC_FSACCESS_ACCESSCHILD sets EXECUTE. * * On NT systems, setting #ISC_FSACCESS_LISTDIRECTORY sets FILE_LIST_DIRECTORY. * ... setting #ISC_FSACCESS_CREATECHILD sets FILE_CREATE_CHILD independently. * ... setting #ISC_FSACCESS_DELETECHILD sets FILE_DELETE_CHILD independently. * ... setting #ISC_FSACCESS_ACCESSCHILD sets FILE_TRAVERSE. * * Unresolved: XXXDCL * \li What NT access right controls the ability to rename a file? * \li How does DELETE work? If a directory has FILE_DELETE_CHILD but a * file or directory within it does not have DELETE, is that file * or directory deletable? * \li To implement isc_fsaccess_get(), mapping an existing Unix permission * mode_t back to an isc_fsaccess_t is pretty trivial; however, mapping * an NT DACL could be impossible to do in a responsible way. * \li Similarly, trying to implement the functionality of being able to * say "add group writability to whatever permissions already exist" * could be tricky on NT because of the order-of-entry issue combined * with possibly having one or more matching ACEs already explicitly * granting or denying access. Because this functionality is * not yet needed by the ISC, no code has been written to try to * solve this problem. */ #include #include /* * Trustees. */ #define ISC_FSACCESS_OWNER 0x1 /*%< User account. */ #define ISC_FSACCESS_GROUP 0x2 /*%< Primary group owner. */ #define ISC_FSACCESS_OTHER 0x4 /*%< Not the owner or the group owner. */ #define ISC_FSACCESS_WORLD 0x7 /*%< User, Group, Other. */ /* * Types of permission. */ #define ISC_FSACCESS_READ 0x00000001 /*%< File only. */ #define ISC_FSACCESS_WRITE 0x00000002 /*%< File only. */ #define ISC_FSACCESS_EXECUTE 0x00000004 /*%< File only. */ #define ISC_FSACCESS_CREATECHILD 0x00000008 /*%< Dir only. */ #define ISC_FSACCESS_DELETECHILD 0x00000010 /*%< Dir only. */ #define ISC_FSACCESS_LISTDIRECTORY 0x00000020 /*%< Dir only. */ #define ISC_FSACCESS_ACCESSCHILD 0x00000040 /*%< Dir only. */ /*% * Adding any permission bits beyond 0x200 would mean typedef'ing * isc_fsaccess_t as isc_uint64_t, and redefining this value to * reflect the new range of permission types, Probably to 21 for * maximum flexibility.

This is an unordered array of index entries * of type journal_rawpos_t giving the locations * of some arbitrary subset of the journal's addressable * transactions. The index entries are used as hints to * speed up the process of locating a transaction with a given * serial number. Unused index entries have an "offset" * field of zero. The size of the index can vary between * journal files, but does not change during the lifetime * of a file. The size can be zero. * * \li The journal data. This consists of one or more transactions. * Each transaction begins with a transaction header of type * journal_rawxhdr_t. The transaction header is followed by a * sequence of RRs, similar in structure to an IXFR difference * sequence (RFC1995). That is, the pre-transaction SOA, * zero or more other deleted RRs, the post-transaction SOA, * and zero or more other added RRs. Unlike in IXFR, each RR * is prefixed with a 32-bit length. * * The journal data part grows as new transactions are * appended to the file.

This implementation uses the RFC 4178 ASN.1 * module but is not a full implementation of the RFC 4178 protocol; * at the moment, we only support GSS-TSIG with Kerberos * authentication, so we only need enough of the SPNEGO protocol to * support that. * * The files that make up this portable SPNEGO implementation are: * \li spnego.c (this file) * \li spnego.h (API SPNEGO exports to the rest of lib/dns) * \li spnego.asn1 (SPNEGO ASN.1 module) * \li spnego_asn1.c (routines generated from spngo.asn1) * \li spnego_asn1.pl (perl script to generate spnego_asn1.c) * * Everything but the functions exported in spnego.h is static, to * avoid possible conflicts with other libraries (particularly Heimdal, * since much of this code comes from Heimdal by way of mod_auth_kerb). * * spnego_asn1.c is shipped as part of lib/dns because generating it * requires both Perl and the Heimdal ASN.1 compiler. See * spnego_asn1.pl for further details. We've tried to eliminate all * compiler warnings from the generated code, but you may see a few * when using a compiler version we haven't tested yet. */ /* * Portions of this code were derived from mod_auth_kerb and Heimdal. * These packages are available from: * * http://modauthkerb.sourceforge.net/ * http://www.pdc.kth.se/heimdal/ * * and were released under the following licenses: * * ---------------------------------------------------------------- * * Copyright (c) 2004 Masarykova universita * (Masaryk University, Brno, Czech Republic) * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions are met: * * 1.

An additional cache entry is expected to be (somehow) * attached to a particular RR in a particular DB node, and contains a set * of information of an additional data for the DB node. * * An additional cache object is intended to be created as a per-view * object, and manages all cache entries within the view. * * The intended usage of the additional caching is to provide a short cut * to additional glue RRs of an NS RR. For each NS RR, it is often * necessary to look for glue RRs to make a proper response. Once the * glue RRs are known, the additional caching allows the client to * associate the information to the original NS RR so that further * expensive lookups can be avoided for the NS RR. * * Each additional cache entry contains information to identify a * particular DB node and (optionally) an associated RRset. The * information consists of its zone, database, the version of the * database, database node, and RRset. * * A "negative" information can also be cached. For example, if a glue * RR does not exist as an authoritative data in the same zone as that * of the NS RR, this fact can be cached by specifying a NULL pointer * for the database, version, and node. (See the description for * dns_acache_getentry() below for more details.) * * Since each member stored in an additional cache entry holds a reference * to a corresponding object, a stale cache entry may cause unnecessary * memory consumption. For instance, when a zone is reloaded, additional * cache entries that have a reference to the zone (and its DB and/or * DB nodes) can delay the cleanup of the referred objects. In order to * minimize such a bad effect, this module provides several cleanup * mechanisms. * * The first one is a shutdown procedure called when the associated view * is shut down. In this case, dns_acache_shutdown() will be called and * all cache entries will be purged. This mechanism will help the * situation when the configuration is reloaded or the main server is * stopped. * * Per-DB cleanup mechanism is also provided. Each additional cache entry * is associated with related DB, which is expected to have been * registered when the DB was created by dns_acache_setdb(). If a * particular DB is going to be destroyed, the primary holder of the DB, * a typical example of which is a zone, will call dns_acache_putdb(). * Then this module will clean-up all cache entries associated with the * DB. This mechanism is effective when a secondary zone DB is going to * be stale after a zone transfer. * * Finally, this module supports for periodic clean-up of stale entries. * Each cache entry has a timestamp field, which is updated every time * the entry is referred. A periodically invoked cleaner checks the * timestamp of each entry, and purge entries that have not been referred * for a certain period. The cleaner interval can be specified by * dns_acache_setcleaninginterval(). If the periodic clean-up is not * enough, it is also possible to specify the upper limit of entries * in terms of the memory consumption. If the maximum value is * specified, the cleaner is invoked when the memory consumption reaches * the high watermark inferred from the maximum value. In this case, * the cleaner will use more aggressive algorithm to decide the "victim" * entries. The maximum value can be specified by * dns_acache_setcachesize(). * * When a cache entry is going to be purged within this module, the * callback function specified at the creation time will be called. * The callback function is expected to release all internal resources * related to the entry, which will typically be specific to DB * implementation, and to call dns_acache_detachentry(). The callback * mechanism is very important, since the holder of an additional cache * entry may not be able to initiate the clean-up of the entry, due to * the reference ordering. For example, as long as an additional cache * entry has a reference to a DB object, the DB cannot be freed, in which * a DB node may have a reference to the cache entry. * * Credits: * The basic idea of this kind of short-cut for frequently used * information is similar to the "pre-compiled answer" approach adopted * in nsd by NLnet LABS with RIPE NCC. Our work here is an independent * effort, but the success of nsd encouraged us to pursue this path. * * The design and implementation of the periodic memory management and * the upper limitation of memory consumption was derived from the cache * DB implementation of BIND9. * * MP: * There are two main locks in this module. One is for each entry, and * the other is for the additional cache object. * * Reliability: * The callback function for a cache entry is called with holding the * entry lock. Thus, it implicitly assumes the callback function does not * call a function that can require the lock. Typically, the only * function that can be called from the callback function safely is * dns_acache_detachentry(). The breakage of this implicit assumption * may cause a deadlock. * * Resources: * In a 32-bit architecture (such as i386), the following additional * memory is required comparing to the case that disables this module. * - 76 bytes for each additional cache entry * - if the entry has a DNS name and associated RRset, * * 44 bytes + size of the name (1-255 bytes) * * 52 bytes x number_of_RRs * - 28 bytes for each DB related to this module * * Using the additional cache also requires extra memory consumption in * the DB implementation. In the current implementation for rbtdb, we * need: * - two additional pointers for each DB node (8 bytes for a 32-bit * architecture * - for each RR associated to an RR in a DB node, we also need * a pointer and management objects to support the additional cache * function.

Various items are checked including the format * of the message (if counts are right, if counts consume the entire sections, * and if sections consume the entire message) and known pseudo-RRs in the * additional data section are analyzed and removed. * * TSIG checking is also done at this layer, and any DNSSEC transaction * signatures should also be checked here. * * Notes on using the gettemp*() and puttemp*() functions: * * These functions return items (names, rdatasets, etc) allocated from some * internal state of the dns_message_t. * * Names and rdatasets must be put back into the dns_message_t in * one of two ways. Assume a name was allocated via * dns_message_gettempname(): * *\li (1) insert it into a section, using dns_message_addname(). * *\li (2) return it to the message using dns_message_puttempname(). * * The same applies to rdatasets. * * On the other hand, offsets, rdatalists and rdatas allocated using * dns_message_gettemp*() will always be freed automatically * when the message is reset or destroyed; calling dns_message_puttemp*() * on rdatalists and rdatas is optional and serves only to enable the item * to be reused multiple times during the lifetime of the message; offsets * cannot be reused. * * Buffers allocated using isc_buffer_allocate() can be automatically freed * as well by giving the buffer to the message using dns_message_takebuffer(). * Doing this will cause the buffer to be freed using isc_buffer_free() * when the section lists are cleared, such as in a reset or in a destroy. * Since the buffer itself exists until the message is destroyed, this sort * of code can be written: * * \code * buffer = isc_buffer_allocate(mctx, 512); * name = NULL; * name = dns_message_gettempname(message, &name); * dns_name_init(name, NULL); * result = dns_name_fromtext(name, &source, dns_rootname, ISC_FALSE, * buffer); * dns_message_takebuffer(message, &buffer); * \endcode * * * TODO: * * XXX Needed: ways to set and retrieve EDNS information, add rdata to a * section, move rdata from one section to another, remove rdata, etc. */ #define DNS_MESSAGEFLAG_QR 0x8000U #define DNS_MESSAGEFLAG_AA 0x0400U #define DNS_MESSAGEFLAG_TC 0x0200U #define DNS_MESSAGEFLAG_RD 0x0100U #define DNS_MESSAGEFLAG_RA 0x0080U #define DNS_MESSAGEFLAG_AD 0x0020U #define DNS_MESSAGEFLAG_CD 0x0010U /*%< EDNS0 extended message flags */ #define DNS_MESSAGEEXTFLAG_DO 0x8000U /*%< EDNS0 extended OPT codes */ #define DNS_OPT_NSID 0x0003 /*%< NSID opt code */ #define DNS_MESSAGE_REPLYPRESERVE (DNS_MESSAGEFLAG_RD|DNS_MESSAGEFLAG_CD) #define DNS_MESSAGEEXTFLAG_REPLYPRESERVE (DNS_MESSAGEEXTFLAG_DO) #define DNS_MESSAGE_HEADERLEN 12 /*%< 6 isc_uint16_t's */ #define DNS_MESSAGE_MAGIC ISC_MAGIC('M','S','G','@') #define DNS_MESSAGE_VALID(msg) ISC_MAGIC_VALID(msg, DNS_MESSAGE_MAGIC) /* * Ordering here matters.

The decision was to store names in uncompressed wire format, * and not to make them fully abstracted objects; i.e. certain parts of the * server know names are stored that way.

Having much of the server know * the representation would be perilous, and we certainly don't want each * user of names to be manipulating such a low-level structure. This is * where the Names and Labels module comes in. The module allows name or * label handles to be created and attached to uncompressed wire format * regions. All name operations and conversions are done through these * handles. * * MP: *\li Clients of this module must impose any required synchronization. * * Reliability: *\li This module deals with low-level byte streams. Errors in any of * the functions are likely to crash the server or corrupt memory. * * Resources: *\li None. * * Security: * *\li *** WARNING *** * *\li dns_name_fromwire() deals with raw network data.

Originally nodes did not have parent * pointers in them (for memory usage reasons) so there was no way to find * the path back to the root from any given node. Now that nodes have parent * pointers, chains might be going away in a future release, though the * movement functionality would remain. * * In any event, parent information, whether via parent pointers or chains, is * necessary information for iterating through the tree or for basic internal * tree maintenance issues (ie, the rotations that are done to rebalance the * tree when a node is added). The obvious implication of this is that for a * chain to remain valid, the tree has to be locked down against writes for the * duration of the useful life of the chain, because additions or removals can * change the path from the root to the node the chain has targeted. * * The dns_rbtnodechain_ functions _first, _last, _prev and _next all take * dns_name_t parameters for the name and the origin, which can be NULL. If * non-NULL, 'name' will end up pointing to the name data and offsets that are * stored at the node (and thus it will be read-only), so it should be a * regular dns_name_t that has been initialized with dns_name_init. When * 'origin' is non-NULL, it will get the name of the origin stored in it, so it * needs to have its own buffer space and offsets, which is most easily * accomplished with a dns_fixedname_t. It is _not_ necessary to reinitialize * either 'name' or 'origin' between calls to the chain functions. * * NOTE WELL: even though the name data at the root of the tree of trees will * be absolute (typically just "."), it will will be made into a relative name * with an origin of "." -- an empty name when the node is ".". This is * because a common on operation on 'name' and 'origin' is to use * dns_name_concatenate() on them to generate the complete name. An empty name * can be detected when dns_name_countlabels == 0, and is printed by * dns_name_totext()/dns_name_format() as "@", consistent with RFC1035's * definition of "@" as the current origin. * * dns_rbtnodechain_current is similar to the _first, _last, _prev and _next * functions but additionally can provide the node to which the chain points. */ /*% * The number of level blocks to allocate at a time.

This saves a lot of memory, and * makes adding rdata to messages easy. Having much of the server know * the representation would be perilous, and we certainly don't want each * user of rdata to be manipulating such a low-level structure. This is * where the rdata module comes in. The module allows rdata handles to be * created and attached to uncompressed wire format regions. All rdata * operations and conversions are done through these handles. * * Implementation Notes: * *\li The routines in this module are expected to be synthesized by the * build process from a set of source files, one per rdata type. For * portability, it's probably best that the building be done by a C * program. Adding a new rdata type will be a simple matter of adding * a file to a directory and rebuilding the server. *All* knowledge of * the format of a particular rdata type is in this file. * * MP: *\li Clients of this module must impose any required synchronization. * * Reliability: *\li This module deals with low-level byte streams. Errors in any of * the functions are likely to crash the server or corrupt memory. * *\li Rdata is typed, and the caller must know what type of rdata it has. * A caller that gets this wrong could crash the server. * *\li The fromstruct() and tostruct() routines use a void * pointer to * represent the structure. The caller must ensure that it passes a * pointer to the appropriate type, or the server could crash or memory * could be corrupted. * * Resources: *\li None. * * Security: * *\li *** WARNING *** * dns_rdata_fromwire() deals with raw network data. An error in * this routine could result in the failure or hijacking of the server. * * Standards: *\li RFC1035 *\li Draft EDNS0 (0) *\li Draft EDNS1 (0) *\li Draft Binary Labels (2) *\li Draft Local Compression (1) *\li Various RFCs for particular types; these will be documented in the * sources files of the types. * */ /*** *** Imports ***/ #include #include #include ISC_LANG_BEGINDECLS /*** *** Types ***/ /*% ***** An 'rdata' is a handle to a binary region.

DNSSEC Release Notes This document summarizes the state of the DNSSEC implementation in this release of BIND9. OpenSSL Library Required To support DNSSEC, BIND 9 must be linked with version 0.9.6e or newer of the OpenSSL library. As of BIND 9.2, the library is no longer included in the distribution - it must be provided by the operating system or installed separately. To build BIND 9 with OpenSSL, use "configure --with-openssl". If the OpenSSL library is installed in a nonstandard location, you can specify a path as in "configure --with-openssl=/var". Key Generation and Signing The tools for generating DNSSEC keys and signatures are now in the bin/dnssec directory. Documentation for these programs can be found in doc/arm/Bv9ARM.4.html and the man pages. The random data used in generating DNSSEC keys and signatures comes from either /dev/random (if the OS supports it) or keyboard input. Alternatively, a device or file containing entropy/random data can be specified. Serving Secure Zones When acting as an authoritative name server, BIND9 includes KEY, SIG and NXT records in responses as specified in RFC2535 when the request has the DO flag set in the query. Secure Resolution Basic support for validation of DNSSEC signatures in responses has been implemented but should still be considered experimental. When acting as a caching name server, BIND9 is capable of performing basic DNSSEC validation of positive as well as nonexistence responses. This functionality is enabled by including a "trusted-keys" clause in the configuration file, containing the top-level zone key of the the DNSSEC tree. Validation of wildcard responses is not currently supported. In particular, a "name does not exist" response will validate successfully even if it does not contain the NXT records to prove the nonexistence of a matching wildcard. Proof of insecure status for insecure zones delegated from secure zones works when the zones are completely insecure. Privately secured zones delegated from secure zones will not work in all cases, such as when the privately secured zone is served by the same server as an ancestor (but not parent) zone. Handling of the CD bit in queries is now fully implemented. Validation is not attempted for recursive queries if CD is set. Secure Dynamic Update Dynamic update of secure zones has been implemented, but may not be complete. Affected NXT and SIG records are updated by the server when an update occurs. Advanced access control is possible using the "update-policy" statement in the zone definition. Secure Zone Transfers BIND 9 does not implement the zone transfer security mechanisms of RFC2535 section 5.6, and we have no plans to implement them in the future as we consider them inferior to the use of TSIG or SIG(0) to ensure the integrity of zone transfers. $Id: dnssec,v 1.19 2004/03/05 05:04:53 marka Exp $ bind-9.6-ESV-R6/doc/misc/format-options.pl000644 024064 023255 00000002740 11734112744 020345 0ustar00eachsweng000000 000000 #!/usr/bin/perl # # Copyright (C) 2004, 2007 Internet Systems Consortium, Inc.

Currently, there are multiple interesting problems with ipv6 implementations on various platforms. These problems range from not being able to use ipv6 with bind9 (or in particular the ISC socket library, contained in libisc) to listen-on lists not being respected, to strange warnings but seemingly correct behavior of named. COMPILE-TIME ISSUES ------------------- The socket library requires a certain level of support from the operating system. In particular, it must follow the advanced ipv6 socket API to be usable. The systems which do not follow this will currently not get any warnings or errors, but ipv6 will simply not function on them. These systems currently include, but are not limited to: AIX 3.4 (with ipv6 patches) RUN-TIME ISSUES --------------- In the original drafts of the ipv6 RFC documents, binding an ipv6 socket to the ipv6 wildcard address would also cause the socket to accept ipv4 connections and datagrams. When an ipv4 packet is received on these systems, it is mapped into an ipv6 address. For example, 1.2.3.4 would be mapped into ::ffff:1.2.3.4. The intent of this mapping was to make transition from an ipv4-only application into ipv6 easier, by only requiring one socket to be open on a given port. Later, it was discovered that this was generally a bad idea. For one, many firewalls will block connection to 1.2.3.4, but will let through ::ffff:1.2.3.4. This, of course, is bad. Also, access control lists written to accept only ipv4 addresses were suddenly ignored unless they were rewritten to handle the ipv6 mapped addresses as well. Partly because of these problems, the latest IPv6 API introduces an explicit knob (the "IPV6_V6ONLY" socket option ) to turn off the ipv6 mapped address usage. In bind9, we first check if both the advanced API and the IPV6_V6ONLY socket option are available. If both of them are available, bind9 named will bind to the ipv6 wildcard port for both TCP and UDP. Otherwise named will make a warning and try to bind to all available ipv6 addresses separately. In any case, bind9 named binds to specific addresses for ipv4 sockets. The followings are historical notes when we always bound to the ipv6 wildcard port regardless of the availability of the API support. These problems should not happen with the closer checks above. IPV6 Sockets Accept IPV4, Specific IPV4 Addresses Bindings Fail --------------------------------------------------------------- The only OS which seems to do this is (some kernel versions of) linux. If an ipv6 socket is bound to the ipv6 wildcard socket, and a specific ipv4 socket is later bound (say, to 1.2.3.4 port 53) the ipv4 binding will fail. What this means to bind9 is that the application will log warnings about being unable to bind to a socket because the address is already in use. Since the ipv6 socket will accept ipv4 packets and map them, however, the ipv4 addresses continue to function. The effect is that the config file listen-on directive will not be respected on these systems. IPV6 Sockets Accept IPV4, Specific IPV4 Address Bindings Succeed ---------------------------------------------------------------- In this case, the system allows opening an ipv6 wildcard address socket and then binding to a more specific ipv4 address later. An example of this type of system is Digital Unix with ipv6 patches applied. What this means to bind9 is that the application will respect listen-on in regards to ipv4 sockets, but it will use mapped ipv6 addresses for any that do not match the listen-on list. This, in effect, makes listen-on useless for these machines as well. IPV6 Sockets Do Not Accept IPV4 ------------------------------- On these systems, opening an IPV6 socket does not implicitly open any ipv4 sockets. An example of these systems are NetBSD-current with the latest KAME patch, and other systems which use the latest KAME patches as their ipv6 implementation. On these systems, listen-on is fully functional, as the ipv6 socket only accepts ipv6 packets, and the ipv4 sockets will handle the ipv4 packets.

BIND 8 to BIND 9 Migration Notes BIND 9 is designed to be mostly upwards compatible with BIND 8, but there is still a number of caveats you should be aware of when upgrading an existing BIND 8 installation to use BIND 9. 1. Configuration File Compatibility 1.1. Unimplemented Options and Changed Defaults BIND 9 supports most, but not all of the named.conf options of BIND 8. For a complete list of implemented options, see doc/misc/options. If your named.conf file uses an unimplemented option, named will log a warning message. A message is also logged about each option whose default has changed unless the option is set explicitly in named.conf. The default of the "transfer-format" option has changed from "one-answer" to "many-answers". If you have slave servers that do not understand the many-answers zone transfer format (e.g., BIND 4.9.5 or older) you need to explicitly specify "transfer-format one-answer;" in either the options block or a server statement. BIND 9.4 onwards implements "allow-query-cache". The "allow-query" option is no longer used to specify access to the cache. The "allow-query" option continues to specify which hosts are allowed to ask ordinary DNS questions. The new "allow-query-cache" option is used to specify which hosts are allowed to get answers from the cache. Since BIND 9.4.1, if "allow-query-cache" is not set then "allow-recursion" is used if it is set, otherwise "allow-query" is used if it is set, otherwise the default localnets and localhost is used. 1.2. Handling of Configuration File Errors In BIND 9, named refuses to start if it detects an error in named.conf. Earlier versions would start despite errors, causing the server to run with a partial configuration. Errors detected during subsequent reloads do not cause the server to exit. Errors in master files do not cause the server to exit, but they do cause the zone not to load. 1.3. Logging The set of logging categories in BIND 9 is different from that in BIND 8. If you have customised your logging on a per-category basis, you need to modify your logging statement to use the new categories. Another difference is that the "logging" statement only takes effect after the entire named.conf file has been read. This means that when the server starts up, any messages about errors in the configuration file are always logged to the default destination (syslog) when the server first starts up, regardless of the contents of the "logging" statement. In BIND 8, the new logging configuration took effect immediately after the "logging" statement was read. 1.4. Notify messages and Refresh queries The source address and port for these is now controlled by "notify-source" and "transfer-source", respectively, rather that query-source as in BIND 8. 1.5. Multiple Classes. Multiple classes have to be put into explicit views for each class. 2. Zone File Compatibility 2.1. Strict RFC1035 Interpretation of TTLs in Zone Files BIND 9 strictly complies with the RFC1035 and RFC2308 rules regarding omitted TTLs in zone files. Omitted TTLs are replaced by the value specified with the $TTL directive, or by the previous explicit TTL if there is no $TTL directive. If there is no $TTL directive and the first RR in the file does not have an explicit TTL field, the zone file is illegal according to RFC1035 since the TTL of the first RR is undefined. Unfortunately, BIND 4 and many versions of BIND 8 accept such files without warning and use the value of the SOA MINTTL field as a default for missing TTL values. BIND 9.0 and 9.1 completely refused to load such files. BIND 9.2 emulates the nonstandard BIND 4/8 SOA MINTTL behaviour and loads the files anyway (provided the SOA is the first record in the file), but will issue the warning message "no TTL specified; using SOA MINTTL instead". To avoid problems, we recommend that you use a $TTL directive in each zone file. 2.2. Periods in SOA Serial Numbers Deprecated Some versions of BIND allow SOA serial numbers with an embedded period, like "3.002", and convert them into integers in a rather unintuitive way. This feature is not supported by BIND 9; serial numbers must be integers. 2.3. Handling of Unbalanced Quotes TXT records with unbalanced quotes, like 'host TXT "foo', were not treated as errors in some versions of BIND. If your zone files contain such records, you will get potentially confusing error messages like "unexpected end of file" because BIND 9 will interpret everything up to the next quote character as a literal string. 2.4. Handling of Line Breaks Some versions of BIND accept RRs containing line breaks that are not properly quoted with parentheses, like the following SOA: @ IN SOA ns.example. hostmaster.example. ( 1 3600 1800 1814400 3600 ) This is not legal master file syntax and will be treated as an error by BIND 9. The fix is to move the opening parenthesis to the first line. 2.5. Unimplemented BIND 8 Extensions $GENERATE: The "$$" construct for getting a literal $ into a domain name is deprecated. Use \$ instead. 2.6. TXT records are no longer automatically split. Some versions of BIND accepted strings in TXT RDATA consisting of more than 255 characters and silently split them to be able to encode the strings in a protocol conformant way. You may now see errors like this dns_rdata_fromtext: local.db:119: ran out of space if you have TXT RRs with too longs strings. Make sure to split the string in the zone data file at or before a single one reaches 255 characters. 3. Interoperability Impact of New Protocol Features 3.1. EDNS0 BIND 9 uses EDNS0 (RFC2671) to advertise its receive buffer size. It also sets DO EDNS flag bit in queries to indicate that it wishes to receive DNSSEC responses. Most older servers that do not support EDNS0, including prior versions of BIND, will send a FORMERR or NOTIMP response to these queries. When this happens, BIND 9 will automatically retry the query without EDNS0. Unfortunately, there exists at least one non-BIND name server implementation that silently ignores these queries instead of sending an error response. Resolving names in zones where all or most authoritative servers use this server will be very slow or fail completely. We have contacted the manufacturer of the name server in case, and they are working on a solution. When BIND 9 communicates with a server that does support EDNS0, such as another BIND 9 server, responses of up to 4096 bytes may be transmitted as a single UDP datagram which is subject to fragmentation at the IP level. If a firewall incorrectly drops IP fragments, it can cause resolution to slow down dramatically or fail. 3.2. Zone Transfers Outgoing zone transfers now use the "many-answers" format by default. This format is not understood by certain old versions of BIND 4. You can work around this problem using the option "transfer-format one-answer;", but since these old versions all have known security problems, the correct fix is to upgrade the slave servers. Zone transfers to Windows 2000 DNS servers sometimes fail due to a bug in the Windows 2000 DNS server where DNS messages larger than 16K are not handled properly. Obtain the latest service pack for Windows 2000 from Microsoft to address this issue. In the meantime, the problem can be worked around by setting "transfer-format one-answer;". http://support.microsoft.com/default.aspx?scid=kb;en-us;297936 4. Unrestricted Character Set BIND 9.2 only BIND 9 does not restrict the character set of domain names - it is fully 8-bit clean in accordance with RFC2181 section 11. It is strongly recommended that hostnames published in the DNS follow the RFC952 rules, but BIND 9 will not enforce this restriction. Historically, some applications have suffered from security flaws where data originating from the network, such as names returned by gethostbyaddr(), are used with insufficient checking and may cause a breach of security when containing unexpected characters; see for details. Some earlier versions of BIND attempt to protect these flawed applications from attack by discarding data containing characters deemed inappropriate in host names or mail addresses, under the control of the "check-names" option in named.conf and/or "options no-check-names" in resolv.conf. BIND 9 provides no such protection; if applications with these flaws are still being used, they should be upgraded. BIND 9.3 onwards implements check-names. 5. Server Administration Tools 5.1 Ndc Replaced by Rndc The "ndc" program has been replaced by "rndc", which is capable of remote operation. Unlike ndc, rndc requires a configuration file. The easiest way to generate a configuration file is to run "rndc-confgen -a"; see the man pages for rndc(8), rndc-confgen(8), and rndc.conf(5) for details. 5.2. Nsupdate Differences The BIND 8 implementation of nsupdate had an undocumented feature where an update request would be broken down into multiple requests based upon the discovered zones that contained the records. This behaviour has not been implemented in BIND 9. Each update request must pertain to a single zone, but it is still possible to do multiple updates in a single invocation of nsupdate by terminating each update with an empty line or a "send" command. 6. No Information Leakage between Zones BIND 9 stores the authoritative data for each zone in a separate data structure, as recommended in RFC1035 and as required by DNSSEC and IXFR. When a BIND 9 server is authoritative for both a child zone and its parent, it will have two distinct sets of NS records at the delegation point: the authoritative NS records at the child's apex, and a set of glue NS records in the parent. BIND 8 was unable to properly distinguish between these two sets of NS records and would "leak" the child's NS records into the parent, effectively causing the parent zone to be silently modified: responses and zone transfers from the parent contained the child's NS records rather than the glue configured into the parent (if any). In the case of children of type "stub", this behaviour was documented as a feature, allowing the glue NS records to be omitted from the parent configuration. Sites that were relying on this BIND 8 behaviour need to add any omitted glue NS records, and any necessary glue A records, to the parent zone. Although stub zones can no longer be used as a mechanism for injecting NS records into their parent zones, they are still useful as a way of directing queries for a given domain to a particular set of name servers. 7. Umask not Modified The BIND 8 named unconditionally sets the umask to 022. BIND 9 does not; the umask inherited from the parent process remains in effect. This may cause files created by named, such as journal files, to be created with different file permissions than they did in BIND 8. If necessary, the umask should be set explicitly in the script used to start the named process. $Id: migration,v 1.49 2008/03/18 15:42:53 jreed Exp $ bind-9.6-ESV-R6/doc/misc/migration-4to9000644 024064 023255 00000004016 11734112744 017536 0ustar00eachsweng000000 000000 Copyright (C) 2004 Internet Systems Consortium, Inc.

There is a conversion tool in contrib/named-bootconf that allows you to do this. named-bootconf.sh < /etc/named.boot > /etc/named.conf BIND 9 uses a system assigned port for the UDP queries it makes rather than port 53 that BIND 4 uses. This may conflict with some firewalls. The following directives in /etc/named.conf allows you to specify a port to use. query-source address * port 53; transfer-source * port 53; notify-source * port 53; BIND 9 no longer uses the minimum field to specify the TTL of records without a explicit TTL. Use the $TTL directive to specify a default TTL before the first record without a explicit TTL. $TTL 3600 @ IN SOA ns1.example.com. hostmaster.example.com. ( 2001021100 7200 1200 3600000 7200 ) BIND 9 does not support multiple CNAMEs with the same owner name. Illegal: www.example.com. CNAME host1.example.com. www.example.com. CNAME host2.example.com. BIND 9 does not support "CNAMEs with other data" with the same owner name, ignoring the DNSSEC records (SIG, NXT, KEY) that BIND 4 did not support. Illegal: www.example.com. CNAME host1.example.com. www.example.com. MX 10 host2.example.com. BIND 9 is less tolerant of errors in master files, so check your logs and fix any errors reported. The named-checkzone program can also be to check master files. Outgoing zone transfers now use the "many-answers" format by default. This format is not understood by certain old versions of BIND 4. You can work around this problem using the option "transfer-format one-answer;", but since these old versions all have known security problems, the correct fix is to upgrade the slave servers. bind-9.6-ESV-R6/doc/misc/options000644 024064 023255 00000055776 11734112744 016466 0ustar00eachsweng000000 000000 This is a summary of the named.conf options supported by this version of BIND 9. acl { ;

Using the BIND 9 Simplified Database Interface This document describes the care and feeding of the BIND 9 Simplified Database Interface, which allows you to extend BIND 9 with new ways of obtaining the data that is published as DNS zones. The Original BIND 9 Database Interface BIND 9 has a well-defined "back-end database interface" that makes it possible to replace the component of the name server responsible for the storage and retrieval of zone data, called the "database", on a per-zone basis. The default database is an in-memory, red-black-tree data structure commonly referred to as "rbtdb", but it is possible to write drivers to support any number of alternative database technologies such as in-memory hash tables, application specific persistent on-disk databases, object databases, or relational databases. The original BIND 9 database interface defined in is designed to efficiently support the full set of database functionality needed by a name server that implements the complete DNS protocols, including features such as zone transfers, dynamic update, and DNSSEC. Each of these aspects of name server operations places its own set of demands on the data store, with the result that the database API is quite complex and contains operations that are highly specific to the DNS. For example, data are stored in a binary format, the name space is tree structured, and sets of data records are conceptually associated with DNSSEC signature sets. For these reasons, writing a driver using this interface is a highly nontrivial undertaking. The Simplified Database Interface Many BIND users wish to provide access to various data sources through the DNS, but are not necessarily interested in completely replacing the in-memory "rbt" database or in supporting features like dynamic update, DNSSEC, or even zone transfers. Often, all you want is limited, read-only DNS access to an existing system. For example, you may have an existing relational database containing hostname/address mappings and wish to provide forvard and reverse DNS lookups based on this information. Or perhaps you want to set up a simple DNS-based load balancing system where the name server answers queries about a single DNS name with a dynamically changing set of A records. BIND 9.1 introduced a new, simplified database interface, or "sdb", which greatly simplifies the writing of drivers for these kinds of applications. The sdb Driver An sdb driver is an object module, typically written in C, which is linked into the name server and registers itself with the sdb subsystem. It provides a set of callback functions, which also serve to advertise its capabilities. When the name server receives DNS queries, invokes the callback functions to obtain the data to respond with. Unlike the full database interface, the sdb interface represents all domain names and resource records as ASCII text. Writing an sdb Driver When a driver is registered, it specifies its name, a list of callback functions, and flags. The flags specify whether the driver wants to use relative domain names where possible. The callback functions are as follows. The only one that must be defined is lookup(). - create(zone, argc, argv, driverdata, dbdata) Create a database object for "zone". - destroy(zone, driverdata, dbdata) Destroy the database object for "zone". - lookup(zone, name, dbdata, lookup) Return all the records at the domain name "name". - authority(zone, dbdata, lookup) Return the SOA and NS records at the zone apex. - allnodes(zone, dbdata, allnodes) Return all data in the zone, for zone transfers. For more detail about these functions and their parameters, see bind9/lib/dns/include/dns/sdb.h. For example drivers, see bind9/contrib/sdb. Rebuilding the Server The driver module and header file must be copied to (or linked into) the bind9/bin/named and bind9/bin/named/include directories respectively, and must be added to the DBDRIVER_OBJS and DBDRIVER_SRCS lines in bin/named/Makefile.in (e.g. for the timedb sample sdb driver, add timedb.c to DBDRIVER_SRCS and timedb.@O@ to DBDRIVER_OBJS). If the driver needs additional header files or libraries in nonstandard places, the DBDRIVER_INCLUDES and DBDRIVER_LIBS lines should also be updated. Calls to dns_sdb_register() and dns_sdb_unregister() (or wrappers, e.g. timedb_init() and timedb_clear() for the timedb sample sdb driver) must be inserted into the server, in bind9/bin/named/main.c. Registration should be in setup(), before the call to ns_server_create(). Unregistration should be in cleanup(), after the call to ns_server_destroy(). A #include should be added corresponding to the driver header file. You should try doing this with one or more of the sample drivers before attempting to write a driver of your own. Configuring the Server To make a zone use a new database driver, specify a "database" option in its "zone" statement in named.conf. For example, if the driver registers itself under the name "acmedb", you might say zone "foo.com" { database "acmedb"; }; You can pass arbitrary arguments to the create() function of the driver by adding any number of whitespace-separated words after the driver name: zone "foo.com" { database "acmedb -mode sql -connect 10.0.0.1"; }; Hints for Driver Writers - If a driver is generating data on the fly, it probably should not implement the allnodes() function, since a zone transfer will not be meaningful. The allnodes() function is more relevant with data from a database. - The authority() function is necessary if and only if the lookup() function will not add SOA and NS records at the zone apex. If SOA and NS records are provided by the lookup() function, the authority() function should be NULL. - When a driver is registered, an opaque object can be provided. This object is passed into the database create() and destroy() functions. - When a database is created, an opaque object can be created that is associated with that database. This object is passed into the lookup(), authority(), and allnodes() functions, and is destroyed by the destroy() function. Future Directions A future release may support dynamic loading of sdb drivers. $Id: sdb,v 1.6 2004/03/05 05:04:54 marka Exp $ bind-9.6-ESV-R6/doc/misc/sort-options.pl000644 024064 023255 00000002544 11734112744 020046 0ustar00eachsweng000000 000000 #!/bin/perl # # Copyright (C) 2007 Internet Systems Consortium, Inc.

("ISC") 2000 2001 2002 2003 Internet Software Consortium. Introduction The Internet Domain Name System (DNS) consists of the syntax to specify the names of entities in the Internet in a hierarchical manner, the rules used for delegating authority over names, and the system implementation that actually maps names to Internet addresses. DNS data is maintained in a group of distributed hierarchical databases. Scope of Document The Berkeley Internet Name Domain (BIND) implements a domain name server for a number of operating systems. This document provides basic information about the installation and care of the Internet Systems Consortium (ISC) BIND version 9 software package for system administrators. This version of the manual corresponds to BIND version 9.6. Organization of This Document In this document, Chapter 1 introduces the basic DNS and BIND concepts. Chapter 2 describes resource requirements for running BIND in various environments. Information in Chapter 3 is task-oriented in its presentation and is organized functionally, to aid in the process of installing the BIND 9 software. The task-oriented section is followed by Chapter 4, which contains more advanced concepts that the system administrator may need for implementing certain options. Chapter 5 describes the BIND 9 lightweight resolver. The contents of Chapter 6 are organized as in a reference manual to aid in the ongoing maintenance of the software. Chapter 7 addresses security considerations, and Chapter 8 contains troubleshooting help. The main body of the document is followed by several appendices which contain useful reference information, such as a bibliography and historic information related to BIND and the Domain Name System. Conventions Used in This Document In this document, we use the following general typographic conventions: To describe: We use the style: a pathname, filename, URL, hostname, mailing list name, or new term or concept Fixed width literal user input Fixed Width Bold program output Fixed Width The following conventions are used in descriptions of the BIND configuration file: To describe: We use the style: keywords Fixed Width variables Fixed Width Optional input Text is enclosed in square brackets The Domain Name System (<acronym>DNS</acronym>) The purpose of this document is to explain the installation and upkeep of the BIND (Berkeley Internet Name Domain) software package, and we begin by reviewing the fundamentals of the Domain Name System (DNS) as they relate to BIND. DNS Fundamentals The Domain Name System (DNS) is a hierarchical, distributed database. It stores information for mapping Internet host names to IP addresses and vice versa, mail routing information, and other data used by Internet applications. Clients look up information in the DNS by calling a resolver library, which sends queries to one or more name servers and interprets the responses. The BIND 9 software distribution contains a name server, named, and a resolver library, liblwres. The older libbind resolver library is also available from ISC as a separate download. Domains and Domain Names The data stored in the DNS is identified by domain names that are organized as a tree according to organizational or administrative boundaries. Each node of the tree, called a domain, is given a label. The domain name of the node is the concatenation of all the labels on the path from the node to the root node. This is represented in written form as a string of labels listed from right to left and separated by dots. A label need only be unique within its parent domain. For example, a domain name for a host at the company Example, Inc. could be ourhost.example.com, where com is the top level domain to which ourhost.example.com belongs, example is a subdomain of com, and ourhost is the name of the host. For administrative purposes, the name space is partitioned into areas called zones, each starting at a node and extending down to the leaf nodes or to nodes where other zones start. The data for each zone is stored in a name server, which answers queries about the zone using the DNS protocol. The data associated with each domain name is stored in the form of resource records (RRs). Some of the supported resource record types are described in . For more detailed information about the design of the DNS and the DNS protocol, please refer to the standards documents listed in . Zones To properly operate a name server, it is important to understand the difference between a zone and a domain. As stated previously, a zone is a point of delegation in the DNS tree. A zone consists of those contiguous parts of the domain tree for which a name server has complete information and over which it has authority. It contains all domain names from a certain point downward in the domain tree except those which are delegated to other zones. A delegation point is marked by one or more NS records in the parent zone, which should be matched by equivalent NS records at the root of the delegated zone. For instance, consider the example.com domain which includes names such as host.aaa.example.com and host.bbb.example.com even though the example.com zone includes only delegations for the aaa.example.com and bbb.example.com zones. A zone can map exactly to a single domain, but could also include only part of a domain, the rest of which could be delegated to other name servers. Every name in the DNS tree is a domain, even if it is terminal, that is, has no subdomains. Every subdomain is a domain and every domain except the root is also a subdomain. The terminology is not intuitive and we suggest that you read RFCs 1033, 1034 and 1035 to gain a complete understanding of this difficult and subtle topic. Though BIND is called a "domain name server", it deals primarily in terms of zones. The master and slave declarations in the named.conf file specify zones, not domains. When you ask some other site if it is willing to be a slave server for your domain, you are actually asking for slave service for some collection of zones. Authoritative Name Servers Each zone is served by at least one authoritative name server, which contains the complete data for the zone. To make the DNS tolerant of server and network failures, most zones have two or more authoritative servers, on different networks. Responses from authoritative servers have the "authoritative answer" (AA) bit set in the response packets. This makes them easy to identify when debugging DNS configurations using tools like dig (). The Primary Master The authoritative server where the master copy of the zone data is maintained is called the primary master server, or simply the primary. Typically it loads the zone contents from some local file edited by humans or perhaps generated mechanically from some other local file which is edited by humans. This file is called the zone file or master file. In some cases, however, the master file may not be edited by humans at all, but may instead be the result of dynamic update operations. Slave Servers The other authoritative servers, the slave servers (also known as secondary servers) load the zone contents from another server using a replication process known as a zone transfer. Typically the data are transferred directly from the primary master, but it is also possible to transfer it from another slave. In other words, a slave server may itself act as a master to a subordinate slave server. Stealth Servers Usually all of the zone's authoritative servers are listed in NS records in the parent zone. These NS records constitute a delegation of the zone from the parent. The authoritative servers are also listed in the zone file itself, at the top level or apex of the zone. You can list servers in the zone's top-level NS records that are not in the parent's NS delegation, but you cannot list servers in the parent's delegation that are not present at the zone's top level. A stealth server is a server that is authoritative for a zone but is not listed in that zone's NS records. Stealth servers can be used for keeping a local copy of a zone to speed up access to the zone's records or to make sure that the zone is available even if all the "official" servers for the zone are inaccessible. A configuration where the primary master server itself is a stealth server is often referred to as a "hidden primary" configuration. One use for this configuration is when the primary master is behind a firewall and therefore unable to communicate directly with the outside world. Caching Name Servers The resolver libraries provided by most operating systems are stub resolvers, meaning that they are not capable of performing the full DNS resolution process by themselves by talking directly to the authoritative servers. Instead, they rely on a local name server to perform the resolution on their behalf. Such a server is called a recursive name server; it performs recursive lookups for local clients. To improve performance, recursive servers cache the results of the lookups they perform. Since the processes of recursion and caching are intimately connected, the terms recursive server and caching server are often used synonymously. The length of time for which a record may be retained in the cache of a caching name server is controlled by the Time To Live (TTL) field associated with each resource record. Forwarding Even a caching name server does not necessarily perform the complete recursive lookup itself. Instead, it can forward some or all of the queries that it cannot satisfy from its cache to another caching name server, commonly referred to as a forwarder. There may be one or more forwarders, and they are queried in turn until the list is exhausted or an answer is found. Forwarders are typically used when you do not wish all the servers at a given site to interact directly with the rest of the Internet servers. A typical scenario would involve a number of internal DNS servers and an Internet firewall. Servers unable to pass packets through the firewall would forward to the server that can do it, and that server would query the Internet DNS servers on the internal server's behalf. Name Servers in Multiple Roles The BIND name server can simultaneously act as a master for some zones, a slave for other zones, and as a caching (recursive) server for a set of local clients. However, since the functions of authoritative name service and caching/recursive name service are logically separate, it is often advantageous to run them on separate server machines. A server that only provides authoritative name service (an authoritative-only server) can run with recursion disabled, improving reliability and security. A server that is not authoritative for any zones and only provides recursive service to local clients (a caching-only server) does not need to be reachable from the Internet at large and can be placed inside a firewall. <acronym>BIND</acronym> Resource Requirements Hardware requirements DNS hardware requirements have traditionally been quite modest. For many installations, servers that have been pensioned off from active duty have performed admirably as DNS servers. The DNSSEC features of BIND 9 may prove to be quite CPU intensive however, so organizations that make heavy use of these features may wish to consider larger systems for these applications. BIND 9 is fully multithreaded, allowing full utilization of multiprocessor systems for installations that need it. CPU Requirements CPU requirements for BIND 9 range from i486-class machines for serving of static zones without caching, to enterprise-class machines if you intend to process many dynamic updates and DNSSEC signed zones, serving many thousands of queries per second. Memory Requirements The memory of the server has to be large enough to fit the cache and zones loaded off disk. The max-cache-size option can be used to limit the amount of memory used by the cache, at the expense of reducing cache hit rates and causing more DNS traffic. Additionally, if additional section caching () is enabled, the max-acache-size option can be used to limit the amount of memory used by the mechanism. It is still good practice to have enough memory to load all zone and cache data into memory — unfortunately, the best way to determine this for a given installation is to watch the name server in operation. After a few weeks the server process should reach a relatively stable size where entries are expiring from the cache as fast as they are being inserted. Name Server Intensive Environment Issues For name server intensive environments, there are two alternative configurations that may be used. The first is where clients and any second-level internal name servers query a main name server, which has enough memory to build a large cache. This approach minimizes the bandwidth used by external name lookups. The second alternative is to set up second-level internal name servers to make queries independently. In this configuration, none of the individual machines needs to have as much memory or CPU power as in the first alternative, but this has the disadvantage of making many more external queries, as none of the name servers share their cached data. Supported Operating Systems ISC BIND 9 compiles and runs on a large number of Unix-like operating systems and on NT-derived versions of Microsoft Windows such as Windows 2000 and Windows XP. For an up-to-date list of supported systems, see the README file in the top level directory of the BIND 9 source distribution. Name Server Configuration In this chapter we provide some suggested configurations along with guidelines for their use. We suggest reasonable values for certain option settings. Sample Configurations A Caching-only Name Server The following sample configuration is appropriate for a caching-only name server for use by clients internal to a corporation. All queries from outside clients are refused using the allow-query option. Alternatively, the same effect could be achieved using suitable firewall rules. // Two corporate subnets we wish to allow queries from. acl corpnets { 192.168.4.0/24; 192.168.7.0/24; }; options { directory "/etc/namedb"; // Working directory allow-query { corpnets; }; }; // Provide a reverse mapping for the loopback address 127.0.0.1 zone "0.0.127.in-addr.arpa" { type master; file "localhost.rev"; notify no; }; An Authoritative-only Name Server This sample configuration is for an authoritative-only server that is the master server for "example.com" and a slave for the subdomain "eng.example.com". options { directory "/etc/namedb"; // Working directory allow-query-cache { none; }; // Do not allow access to cache allow-query { any; }; // This is the default recursion no; // Do not provide recursive service }; // Provide a reverse mapping for the loopback address 127.0.0.1 zone "0.0.127.in-addr.arpa" { type master; file "localhost.rev"; notify no; }; // We are the master server for example.com zone "example.com" { type master; file "example.com.db"; // IP addresses of slave servers allowed to transfer example.com allow-transfer { 192.168.4.14; 192.168.5.53; }; }; // We are a slave server for eng.example.com zone "eng.example.com" { type slave; file "eng.example.com.bk"; // IP address of eng.example.com master server masters { 192.168.4.12; }; }; Load Balancing A primitive form of load balancing can be achieved in the DNS by using multiple records (such as multiple A records) for one name. For example, if you have three WWW servers with network addresses of 10.0.0.1, 10.0.0.2 and 10.0.0.3, a set of records such as the following means that clients will connect to each machine one third of the time: Name TTL CLASS TYPE Resource Record (RR) Data www 600 IN A 10.0.0.1 600 IN A 10.0.0.2 600 IN A 10.0.0.3 When a resolver queries for these records, BIND will rotate them and respond to the query with the records in a different order. In the example above, clients will randomly receive records in the order 1, 2, 3; 2, 3, 1; and 3, 1, 2. Most clients will use the first record returned and discard the rest. For more detail on ordering responses, check the rrset-order sub-statement in the options statement, see . Name Server Operations Tools for Use With the Name Server Daemon This section describes several indispensable diagnostic, administrative and monitoring tools available to the system administrator for controlling and debugging the name server daemon. Diagnostic Tools The dig, host, and nslookup programs are all command line tools for manually querying name servers. They differ in style and output format. dig The domain information groper (dig) is the most versatile and complete of these lookup tools. It has two modes: simple interactive mode for a single query, and batch mode which executes a query for each in a list of several query lines. All query options are accessible from the command line. dig @server domain query-type query-class +query-option -dig-option %comment The usual simple use of dig will take the form dig @server domain query-type query-class For more information and a list of available commands and options, see the dig man page. host The host utility emphasizes simplicity and ease of use. By default, it converts between host names and Internet addresses, but its functionality can be extended with the use of options. host -aCdlnrsTwv -c class -N ndots -t type -W timeout -R retries -m flag -4 -6 hostname server For more information and a list of available commands and options, see the host man page. nslookup nslookup has two modes: interactive and non-interactive. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. Non-interactive mode is used to print just the name and requested information for a host or domain. nslookup -option host-to-find - server Interactive mode is entered when no arguments are given (the default name server will be used) or when the first argument is a hyphen (`-') and the second argument is the host name or Internet address of a name server. Non-interactive mode is used when the name or Internet address of the host to be looked up is given as the first argument. The optional second argument specifies the host name or address of a name server. Due to its arcane user interface and frequently inconsistent behavior, we do not recommend the use of nslookup. Use dig instead. Administrative Tools Administrative tools play an integral part in the management of a server. named-checkconf The named-checkconf program checks the syntax of a named.conf file. named-checkconf -jvz -t directory filename named-checkzone The named-checkzone program checks a master file for syntax and consistency. named-checkzone -djqvD -c class -o output -t directory -w directory -k (ignore|warn|fail) -n (ignore|warn|fail) -W (ignore|warn) zone filename named-compilezone Similar to named-checkzone, but it always dumps the zone content to a specified file (typically in a different format). rndc The remote name daemon control (rndc) program allows the system administrator to control the operation of a name server. Since BIND 9.2, rndc supports all the commands of the BIND 8 ndc utility except ndc start and ndc restart, which were also not supported in ndc's channel mode. If you run rndc without any options it will display a usage message as follows: rndc -c config -s server -p port -y key command command The command is one of the following: reload Reload configuration file and zones. reload zone class view Reload the given zone. refresh zone class view Schedule zone maintenance for the given zone. retransfer zone class view Retransfer the given zone from the master. freeze zone class view Suspend updates to a dynamic zone. If no zone is specified, then all zones are suspended. This allows manual edits to be made to a zone normally updated by dynamic update. It also causes changes in the journal file to be synced into the master and the journal file to be removed. All dynamic update attempts will be refused while the zone is frozen. thaw zone class view Enable updates to a frozen dynamic zone. If no zone is specified, then all frozen zones are enabled. This causes the server to reload the zone from disk, and re-enables dynamic updates after the load has completed. After a zone is thawed, dynamic updates will no longer be refused. notify zone class view Resend NOTIFY messages for the zone. reconfig Reload the configuration file and load new zones, but do not reload existing zone files even if they have changed. This is faster than a full reload when there is a large number of zones because it avoids the need to examine the modification times of the zones files. stats Write server statistics to the statistics file. querylog Toggle query logging. Query logging can also be enabled by explicitly directing the queries category to a channel in the logging section of named.conf or by specifying querylog yes; in the options section of named.conf. dumpdb -all|-cache|-zone view ... Dump the server's caches (default) and/or zones to the dump file for the specified views. If no view is specified, all views are dumped. stop -p Stop the server, making sure any recent changes made through dynamic update or IXFR are first saved to the master files of the updated zones. If is specified named's process id is returned. This allows an external process to determine when named had completed stopping. halt -p Stop the server immediately. Recent changes made through dynamic update or IXFR are not saved to the master files, but will be rolled forward from the journal files when the server is restarted. If is specified named's process id is returned. This allows an external process to determine when named had completed halting. trace Increment the servers debugging level by one. trace level Sets the server's debugging level to an explicit value. notrace Sets the server's debugging level to 0. flush Flushes the server's cache. flushname name Flushes the given name from the server's cache. status Display status of the server. Note that the number of zones includes the internal bind/CH zone and the default ./IN hint zone if there is not an explicit root zone configured. tsig-list List the names of all TSIG keys currently configured for use by named in each view. The list both statically configured keys and dynamic TKEY-negotiated keys. tsig-delete keyname view Delete a given TKEY-negotated key from the server. (This does not apply to statically configured TSIG keys.) recursing Dump the list of queries named is currently recursing on. validation on|off view ... Enable or disable DNSSEC validation. Note dnssec-enable also needs to be set to yes to be effective. It defaults to enabled. A configuration file is required, since all communication with the server is authenticated with digital signatures that rely on a shared secret, and there is no way to provide that secret other than with a configuration file. The default location for the rndc configuration file is /etc/rndc.conf, but an alternate location can be specified with the option. If the configuration file is not found, rndc will also look in /etc/rndc.key (or whatever sysconfdir was defined when the BIND build was configured). The rndc.key file is generated by running rndc-confgen -a as described in . The format of the configuration file is similar to that of named.conf, but limited to only four statements, the options, key, server and include statements. These statements are what associate the secret keys to the servers with which they are meant to be shared. The order of statements is not significant. The options statement has three clauses: default-server, default-key, and default-port. default-server takes a host name or address argument and represents the server that will be contacted if no option is provided on the command line. default-key takes the name of a key as its argument, as defined by a key statement. default-port specifies the port to which rndc should connect if no port is given on the command line or in a server statement. The key statement defines a key to be used by rndc when authenticating with named. Its syntax is identical to the key statement in named.conf. The keyword key is followed by a key name, which must be a valid domain name, though it need not actually be hierarchical; thus, a string like "rndc_key" is a valid name. The key statement has two clauses: algorithm and secret. While the configuration parser will accept any string as the argument to algorithm, currently only the string "hmac-md5" has any meaning. The secret is a base-64 encoded string as specified in RFC 3548. The server statement associates a key defined using the key statement with a server. The keyword server is followed by a host name or address. The server statement has two clauses: key and port. The key clause specifies the name of the key to be used when communicating with this server, and the port clause can be used to specify the port rndc should connect to on the server. A sample minimal configuration file is as follows: key rndc_key { algorithm "hmac-md5"; secret "c3Ryb25nIGVub3VnaCBmb3IgYSBtYW4gYnV0IG1hZGUgZm9yIGEgd29tYW4K"; }; options { default-server 127.0.0.1; default-key rndc_key; }; This file, if installed as /etc/rndc.conf, would allow the command: $ rndc reload to connect to 127.0.0.1 port 953 and cause the name server to reload, if a name server on the local machine were running with following controls statements: controls { inet 127.0.0.1 allow { localhost; } keys { rndc_key; }; }; and it had an identical key statement for rndc_key. Running the rndc-confgen program will conveniently create a rndc.conf file for you, and also display the corresponding controls statement that you need to add to named.conf. Alternatively, you can run rndc-confgen -a to set up a rndc.key file and not modify named.conf at all. Signals Certain UNIX signals cause the name server to take specific actions, as described in the following table. These signals can be sent using the kill command. SIGHUP Causes the server to read named.conf and reload the database. SIGTERM Causes the server to clean up and exit. SIGINT Causes the server to clean up and exit. Advanced DNS Features Notify DNS NOTIFY is a mechanism that allows master servers to notify their slave servers of changes to a zone's data. In response to a NOTIFY from a master server, the slave will check to see that its version of the zone is the current version and, if not, initiate a zone transfer. For more information about DNS NOTIFY, see the description of the notify option in and the description of the zone option also-notify in . The NOTIFY protocol is specified in RFC 1996. As a slave zone can also be a master to other slaves, named, by default, sends NOTIFY messages for every zone it loads. Specifying notify master-only; will cause named to only send NOTIFY for master zones that it loads. Dynamic Update Dynamic Update is a method for adding, replacing or deleting records in a master server by sending it a special form of DNS messages. The format and meaning of these messages is specified in RFC 2136. Dynamic update is enabled by including an allow-update or update-policy clause in the zone statement. The tkey-gssapi-credential and tkey-domain clauses in the options statement enable the server to negotiate keys that can be matched against those in update-policy or allow-update. Updating of secure zones (zones using DNSSEC) follows RFC 3007: RRSIG, NSEC and NSEC3 records affected by updates are automatically regenerated by the server using an online zone key. Update authorization is based on transaction signatures and an explicit server policy. The journal file All changes made to a zone using dynamic update are stored in the zone's journal file. This file is automatically created by the server when the first dynamic update takes place. The name of the journal file is formed by appending the extension .jnl to the name of the corresponding zone file unless specifically overridden. The journal file is in a binary format and should not be edited manually. The server will also occasionally write ("dump") the complete contents of the updated zone to its zone file. This is not done immediately after each dynamic update, because that would be too slow when a large zone is updated frequently. Instead, the dump is delayed by up to 15 minutes, allowing additional updates to take place. During the dump process, transient files will be created with the extensions .jnw and .jbk; under ordinary circumstances, these will be removed when the dump is complete, and can be safely ignored. When a server is restarted after a shutdown or crash, it will replay the journal file to incorporate into the zone any updates that took place after the last zone dump. Changes that result from incoming incremental zone transfers are also journalled in a similar way. The zone files of dynamic zones cannot normally be edited by hand because they are not guaranteed to contain the most recent dynamic changes — those are only in the journal file. The only way to ensure that the zone file of a dynamic zone is up to date is to run rndc stop. If you have to make changes to a dynamic zone manually, the following procedure will work: Disable dynamic updates to the zone using rndc freeze zone. This will also remove the zone's .jnl file and update the master file. Edit the zone file. Run rndc thaw zone to reload the changed zone and re-enable dynamic updates. Incremental Zone Transfers (IXFR) The incremental zone transfer (IXFR) protocol is a way for slave servers to transfer only changed data, instead of having to transfer the entire zone. The IXFR protocol is specified in RFC 1995. See . When acting as a master, BIND 9 supports IXFR for those zones where the necessary change history information is available. These include master zones maintained by dynamic update and slave zones whose data was obtained by IXFR. For manually maintained master zones, and for slave zones obtained by performing a full zone transfer (AXFR), IXFR is supported only if the option ixfr-from-differences is set to yes. When acting as a slave, BIND 9 will attempt to use IXFR unless it is explicitly disabled via the request-ixfr option or the use of ixfr-from-differences. For more information about disabling IXFR, see the description of the request-ixfr clause of the server statement. Split DNS Setting up different views, or visibility, of the DNS space to internal and external resolvers is usually referred to as a Split DNS setup. There are several reasons an organization would want to set up its DNS this way. One common reason for setting up a DNS system this way is to hide "internal" DNS information from "external" clients on the Internet. There is some debate as to whether or not this is actually useful. Internal DNS information leaks out in many ways (via email headers, for example) and most savvy "attackers" can find the information they need using other means. However, since listing addresses of internal servers that external clients cannot possibly reach can result in connection delays and other annoyances, an organization may choose to use a Split DNS to present a consistent view of itself to the outside world. Another common reason for setting up a Split DNS system is to allow internal networks that are behind filters or in RFC 1918 space (reserved IP space, as documented in RFC 1918) to resolve DNS on the Internet. Split DNS can also be used to allow mail from outside back in to the internal network. Example split DNS setup Let's say a company named Example, Inc. (example.com) has several corporate sites that have an internal network with reserved Internet Protocol (IP) space and an external demilitarized zone (DMZ), or "outside" section of a network, that is available to the public. Example, Inc. wants its internal clients to be able to resolve external hostnames and to exchange mail with people on the outside. The company also wants its internal resolvers to have access to certain internal-only zones that are not available at all outside of the internal network. In order to accomplish this, the company will set up two sets of name servers. One set will be on the inside network (in the reserved IP space) and the other set will be on bastion hosts, which are "proxy" hosts that can talk to both sides of its network, in the DMZ. The internal servers will be configured to forward all queries, except queries for site1.internal, site2.internal, site1.example.com, and site2.example.com, to the servers in the DMZ. These internal servers will have complete sets of information for site1.example.com, site2.example.com, site1.internal, and site2.internal. To protect the site1.internal and site2.internal domains, the internal name servers must be configured to disallow all queries to these domains from any external hosts, including the bastion hosts. The external servers, which are on the bastion hosts, will be configured to serve the "public" version of the site1 and site2.example.com zones. This could include things such as the host records for public servers (www.example.com and ftp.example.com), and mail exchange (MX) records (a.mx.example.com and b.mx.example.com). In addition, the public site1 and site2.example.com zones should have special MX records that contain wildcard (`*') records pointing to the bastion hosts. This is needed because external mail servers do not have any other way of looking up how to deliver mail to those internal hosts. With the wildcard records, the mail will be delivered to the bastion host, which can then forward it on to internal hosts. Here's an example of a wildcard MX record: * IN MX 10 external1.example.com. Now that they accept mail on behalf of anything in the internal network, the bastion hosts will need to know how to deliver mail to internal hosts. In order for this to work properly, the resolvers on the bastion hosts will need to be configured to point to the internal name servers for DNS resolution. Queries for internal hostnames will be answered by the internal servers, and queries for external hostnames will be forwarded back out to the DNS servers on the bastion hosts. In order for all this to work properly, internal clients will need to be configured to query only the internal name servers for DNS queries. This could also be enforced via selective filtering on the network. If everything has been set properly, Example, Inc.'s internal clients will now be able to: Look up any hostnames in the site1 and site2.example.com zones. Look up any hostnames in the site1.internal and site2.internal domains. Look up any hostnames on the Internet. Exchange mail with both internal and external people. Hosts on the Internet will be able to: Look up any hostnames in the site1 and site2.example.com zones. Exchange mail with anyone in the site1 and site2.example.com zones. Here is an example configuration for the setup we just described above. Note that this is only configuration information; for information on how to configure your zone files, see . Internal DNS server config: acl internals { 172.16.72.0/24; 192.168.1.0/24; }; acl externals { bastion-ips-go-here; }; options { ... ... forward only; forwarders { // forward to external servers bastion-ips-go-here; }; allow-transfer { none; }; // sample allow-transfer (no one) allow-query { internals; externals; }; // restrict query access allow-recursion { internals; }; // restrict recursion ... ... }; zone "site1.example.com" { // sample master zone type master; file "m/site1.example.com"; forwarders { }; // do normal iterative // resolution (do not forward) allow-query { internals; externals; }; allow-transfer { internals; }; }; zone "site2.example.com" { // sample slave zone type slave; file "s/site2.example.com"; masters { 172.16.72.3; }; forwarders { }; allow-query { internals; externals; }; allow-transfer { internals; }; }; zone "site1.internal" { type master; file "m/site1.internal"; forwarders { }; allow-query { internals; }; allow-transfer { internals; } }; zone "site2.internal" { type slave; file "s/site2.internal"; masters { 172.16.72.3; }; forwarders { }; allow-query { internals }; allow-transfer { internals; } }; External (bastion host) DNS server config: acl internals { 172.16.72.0/24; 192.168.1.0/24; }; acl externals { bastion-ips-go-here; }; options { ... ... allow-transfer { none; }; // sample allow-transfer (no one) allow-query { any; }; // default query access allow-query-cache { internals; externals; }; // restrict cache access allow-recursion { internals; externals; }; // restrict recursion ... ... }; zone "site1.example.com" { // sample slave zone type master; file "m/site1.foo.com"; allow-transfer { internals; externals; }; }; zone "site2.example.com" { type slave; file "s/site2.foo.com"; masters { another_bastion_host_maybe; }; allow-transfer { internals; externals; } }; In the resolv.conf (or equivalent) on the bastion host(s): search ... nameserver 172.16.72.2 nameserver 172.16.72.3 nameserver 172.16.72.4 TSIG This is a short guide to setting up Transaction SIGnatures (TSIG) based transaction security in BIND. It describes changes to the configuration file as well as what changes are required for different features, including the process of creating transaction keys and using transaction signatures with BIND. BIND primarily supports TSIG for server to server communication. This includes zone transfer, notify, and recursive query messages. Resolvers based on newer versions of BIND 8 have limited support for TSIG. TSIG can also be useful for dynamic update. A primary server for a dynamic zone should control access to the dynamic update service, but IP-based access control is insufficient. The cryptographic access control provided by TSIG is far superior. The nsupdate program supports TSIG via the and command line options or inline by use of the key. Generate Shared Keys for Each Pair of Hosts A shared secret is generated to be shared between host1 and host2. An arbitrary key name is chosen: "host1-host2.". The key name must be the same on both hosts. Automatic Generation The following command will generate a 128-bit (16 byte) HMAC-SHA256 key as described above. Longer keys are better, but shorter keys are easier to read. Note that the maximum key length is the digest length, here 256 bits. dnssec-keygen -a hmac-sha256 -b 128 -n HOST host1-host2. The key is in the file Khost1-host2.+163+00000.private. Nothing directly uses this file, but the base-64 encoded string following "Key:" can be extracted from the file and used as a shared secret: Key: La/E5CjG9O+os1jq0a2jdA== The string "La/E5CjG9O+os1jq0a2jdA==" can be used as the shared secret. Manual Generation The shared secret is simply a random sequence of bits, encoded in base-64. Most ASCII strings are valid base-64 strings (assuming the length is a multiple of 4 and only valid characters are used), so the shared secret can be manually generated. Also, a known string can be run through mmencode or a similar program to generate base-64 encoded data. Copying the Shared Secret to Both Machines This is beyond the scope of DNS. A secure transport mechanism should be used. This could be secure FTP, ssh, telephone, etc. Informing the Servers of the Key's Existence Imagine host1 and host 2 are both servers. The following is added to each server's named.conf file: key host1-host2. { algorithm hmac-sha256; secret "La/E5CjG9O+os1jq0a2jdA=="; }; The secret is the one generated above. Since this is a secret, it is recommended that either named.conf be non-world readable, or the key directive be added to a non-world readable file that is included by named.conf. At this point, the key is recognized. This means that if the server receives a message signed by this key, it can verify the signature. If the signature is successfully verified, the response is signed by the same key. Instructing the Server to Use the Key Since keys are shared between two hosts only, the server must be told when keys are to be used. The following is added to the named.conf file for host1, if the IP address of host2 is 10.1.2.3: server 10.1.2.3 { keys { host1-host2. ;}; }; Multiple keys may be present, but only the first is used. This directive does not contain any secrets, so it may be in a world-readable file. If host1 sends a message that is a request to that address, the message will be signed with the specified key. host1 will expect any responses to signed messages to be signed with the same key. A similar statement must be present in host2's configuration file (with host1's address) for host2 to sign request messages to host1. TSIG Key Based Access Control BIND allows IP addresses and ranges to be specified in ACL definitions and allow-{ query | transfer | update } directives. This has been extended to allow TSIG keys also. The above key would be denoted key host1-host2. An example of an allow-update directive would be: allow-update { key host1-host2. ;}; This allows dynamic updates to succeed only if the request was signed by a key named "host1-host2.". You may want to read about the more powerful update-policy statement in . Errors The processing of TSIG signed messages can result in several errors. If a signed message is sent to a non-TSIG aware server, a FORMERR (format error) will be returned, since the server will not understand the record. This is a result of misconfiguration, since the server must be explicitly configured to send a TSIG signed message to a specific server. If a TSIG aware server receives a message signed by an unknown key, the response will be unsigned with the TSIG extended error code set to BADKEY. If a TSIG aware server receives a message with a signature that does not validate, the response will be unsigned with the TSIG extended error code set to BADSIG. If a TSIG aware server receives a message with a time outside of the allowed range, the response will be signed with the TSIG extended error code set to BADTIME, and the time values will be adjusted so that the response can be successfully verified. In any of these cases, the message's rcode (response code) is set to NOTAUTH (not authenticated). TKEY TKEY is a mechanism for automatically generating a shared secret between two hosts. There are several "modes" of TKEY that specify how the key is generated or assigned. BIND 9 implements only one of these modes, the Diffie-Hellman key exchange. Both hosts are required to have a Diffie-Hellman KEY record (although this record is not required to be present in a zone). The TKEY process must use signed messages, signed either by TSIG or SIG(0). The result of TKEY is a shared secret that can be used to sign messages with TSIG. TKEY can also be used to delete shared secrets that it had previously generated. The TKEY process is initiated by a client or server by sending a signed TKEY query (including any appropriate KEYs) to a TKEY-aware server. The server response, if it indicates success, will contain a TKEY record and any appropriate keys. After this exchange, both participants have enough information to determine the shared secret; the exact process depends on the TKEY mode. When using the Diffie-Hellman TKEY mode, Diffie-Hellman keys are exchanged, and the shared secret is derived by both participants. SIG(0) BIND 9 partially supports DNSSEC SIG(0) transaction signatures as specified in RFC 2535 and RFC 2931. SIG(0) uses public/private keys to authenticate messages. Access control is performed in the same manner as TSIG keys; privileges can be granted or denied based on the key name. When a SIG(0) signed message is received, it will only be verified if the key is known and trusted by the server; the server will not attempt to locate and/or validate the key. SIG(0) signing of multiple-message TCP streams is not supported. The only tool shipped with BIND 9 that generates SIG(0) signed messages is nsupdate. DNSSEC Cryptographic authentication of DNS information is possible through the DNS Security (DNSSEC-bis) extensions, defined in RFC 4033, RFC 4034, and RFC 4035. This section describes the creation and use of DNSSEC signed zones. In order to set up a DNSSEC secure zone, there are a series of steps which must be followed. BIND 9 ships with several tools that are used in this process, which are explained in more detail below. In all cases, the option prints a full list of parameters. Note that the DNSSEC tools require the keyset files to be in the working directory or the directory specified by the option, and that the tools shipped with BIND 9.2.x and earlier are not compatible with the current ones. There must also be communication with the administrators of the parent and/or child zone to transmit keys. A zone's security status must be indicated by the parent zone for a DNSSEC capable resolver to trust its data. This is done through the presence or absence of a DS record at the delegation point. For other servers to trust data in this zone, they must either be statically configured with this zone's zone key or the zone key of another zone above this one in the DNS tree. Generating Keys The dnssec-keygen program is used to generate keys. A secure zone must contain one or more zone keys. The zone keys will sign all other records in the zone, as well as the zone keys of any secure delegated zones. Zone keys must have the same name as the zone, a name type of ZONE, and must be usable for authentication. It is recommended that zone keys use a cryptographic algorithm designated as "mandatory to implement" by the IETF; currently the only one is RSASHA1. The following command will generate a 768-bit RSASHA1 key for the child.example zone: dnssec-keygen -a RSASHA1 -b 768 -n ZONE child.example. Two output files will be produced: Kchild.example.+005+12345.key and Kchild.example.+005+12345.private (where 12345 is an example of a key tag). The key filenames contain the key name (child.example.), algorithm (3 is DSA, 1 is RSAMD5, 5 is RSASHA1, etc.), and the key tag (12345 in this case). The private key (in the .private file) is used to generate signatures, and the public key (in the .key file) is used for signature verification. To generate another key with the same properties (but with a different key tag), repeat the above command. The dnssec-keyfromlabel program is used to get a key pair from a crypto hardware and build the key files. Its usage is similar to dnssec-keygen. The public keys should be inserted into the zone file by including the .key files using $INCLUDE statements. Signing the Zone The dnssec-signzone program is used to sign a zone. Any keyset files corresponding to secure subzones should be present. The zone signer will generate NSEC, NSEC3 and RRSIG records for the zone, as well as DS for the child zones if '-g' is specified. If '-g' is not specified, then DS RRsets for the secure child zones need to be added manually. The following command signs the zone, assuming it is in a file called zone.child.example. By default, all zone keys which have an available private key are used to generate signatures. dnssec-signzone -o child.example zone.child.example One output file is produced: zone.child.example.signed. This file should be referenced by named.conf as the input file for the zone. dnssec-signzone will also produce a keyset and dsset files and optionally a dlvset file. These are used to provide the parent zone administrators with the DNSKEYs (or their corresponding DS records) that are the secure entry point to the zone. Configuring Servers To enable named to respond appropriately to DNS requests from DNSSEC aware clients, dnssec-enable must be set to yes. (This is the default setting.) To enable named to validate answers from other servers, the dnssec-enable and dnssec-validation options must both be set to yes (the default setting in BIND 9.5 and later), and at least one trust anchor must be configured with a trusted-keys statement in named.conf. trusted-keys are copies of DNSKEY RRs for zones that are used to form the first link in the cryptographic chain of trust. All keys listed in trusted-keys (and corresponding zones) are deemed to exist and only the listed keys will be used to validated the DNSKEY RRset that they are from. trusted-keys are described in more detail later in this document. Unlike BIND 8, BIND 9 does not verify signatures on load, so zone keys for authoritative zones do not need to be specified in the configuration file. After DNSSEC gets established, a typical DNSSEC configuration will look something like the following. It has a one or more public keys for the root. This allows answers from outside the organization to be validated. It will also have several keys for parts of the namespace the organization controls. These are here to ensure that named is immune to compromises in the DNSSEC components of the security of parent zones. trusted-keys { /* Root Key */ "." 257 3 3 "BNY4wrWM1nCfJ+CXd0rVXyYmobt7sEEfK3clRbGaTwSJxrGkxJWoZu6I7PzJu/ E9gx4UC1zGAHlXKdE4zYIpRhaBKnvcC2U9mZhkdUpd1Vso/HAdjNe8LmMlnzY3 zy2Xy4klWOADTPzSv9eamj8V18PHGjBLaVtYvk/ln5ZApjYghf+6fElrmLkdaz MQ2OCnACR817DF4BBa7UR/beDHyp5iWTXWSi6XmoJLbG9Scqc7l70KDqlvXR3M /lUUVRbkeg1IPJSidmK3ZyCllh4XSKbje/45SKucHgnwU5jefMtq66gKodQj+M iA21AfUVe7u99WzTLzY3qlxDhxYQQ20FQ97S+LKUTpQcq27R7AT3/V5hRQxScI Nqwcz4jYqZD2fQdgxbcDTClU0CRBdiieyLMNzXG3"; /* Key for our organization's forward zone */ example.com. 257 3 5 "AwEAAaxPMcR2x0HbQV4WeZB6oEDX+r0QM65KbhTjrW1ZaARmPhEZZe 3Y9ifgEuq7vZ/zGZUdEGNWy+JZzus0lUptwgjGwhUS1558Hb4JKUbb OTcM8pwXlj0EiX3oDFVmjHO444gLkBO UKUf/mC7HvfwYH/Be22GnC lrinKJp1Og4ywzO9WglMk7jbfW33gUKvirTHr25GL7STQUzBb5Usxt 8lgnyTUHs1t3JwCY5hKZ6CqFxmAVZP20igTixin/1LcrgX/KMEGd/b iuvF4qJCyduieHukuY3H4XMAcR+xia2 nIUPvm/oyWR8BW/hWdzOvn SCThlHf3xiYleDbt/o1OTQ09A0="; /* Key for our reverse zone. */ 2.0.192.IN-ADDRPA.NET. 257 3 5 "AQOnS4xn/IgOUpBPJ3bogzwcxOdNax071L18QqZnQQQA VVr+iLhGTnNGp3HoWQLUIzKrJVZ3zggy3WwNT6kZo6c0 tszYqbtvchmgQC8CzKojM/W16i6MG/ea fGU3siaOdS0 yOI6BgPsw+YZdzlYMaIJGf4M4dyoKIhzdZyQ2bYQrjyQ 4LB0lC7aOnsMyYKHHYeRv PxjIQXmdqgOJGq+vsevG06 zW+1xgYJh9rCIfnm1GX/KMgxLPG2vXTD/RnLX+D3T3UL 7HJYHJhAZD5L59VvjSPsZJHeDCUyWYrvPZesZDIRvhDD 52SKvbheeTJUm6EhkzytNN2SN96QRk8j/iI8ib"; }; options { ... dnssec-enable yes; dnssec-validation yes; }; None of the keys listed in this example are valid. In particular, the root key is not valid. When DNSSEC validation is enabled and properly configured, the resolver will reject any answers from signed, secure zones which fail to validate, and will return SERVFAIL to the client. Responses may fail to validate for any of several reasons, including missing, expired, or invalid signatures, a key which does not match the DS RRset in the parent zone, or an insecure response from a zone which, according to its parent, should have been secure. When the validator receives a response from an unsigned zone that has a signed parent, it must confirm with the parent that the zone was intentionally left unsigned. It does this by verifying, via signed and validated NSEC/NSEC3 records, that the parent zone contains no DS records for the child. If the validator can prove that the zone is insecure, then the response is accepted. However, if it cannot, then it must assume an insecure response to be a forgery; it rejects the response and logs an error. The logged error reads "insecurity proof failed" and "got insecure response; parent indicates it should be secure". (Prior to BIND 9.7, the logged error was "not insecure". This referred to the zone, not the response.) IPv6 Support in <acronym>BIND</acronym> 9 BIND 9 fully supports all currently defined forms of IPv6 name to address and address to name lookups. It will also use IPv6 addresses to make queries when running on an IPv6 capable system. For forward lookups, BIND 9 supports only AAAA records. RFC 3363 deprecated the use of A6 records, and client-side support for A6 records was accordingly removed from BIND 9. However, authoritative BIND 9 name servers still load zone files containing A6 records correctly, answer queries for A6 records, and accept zone transfer for a zone containing A6 records. For IPv6 reverse lookups, BIND 9 supports the traditional "nibble" format used in the ip6.arpa domain, as well as the older, deprecated ip6.int domain. Older versions of BIND 9 supported the "binary label" (also known as "bitstring") format, but support of binary labels has been completely removed per RFC 3363. Many applications in BIND 9 do not understand the binary label format at all any more, and will return an error if given. In particular, an authoritative BIND 9 name server will not load a zone file containing binary labels. For an overview of the format and structure of IPv6 addresses, see . Address Lookups Using AAAA Records The IPv6 AAAA record is a parallel to the IPv4 A record, and, unlike the deprecated A6 record, specifies the entire IPv6 address in a single record. For example, $ORIGIN example.com. host 3600 IN AAAA 2001:db8::1 Use of IPv4-in-IPv6 mapped addresses is not recommended. If a host has an IPv4 address, use an A record, not a AAAA, with ::ffff:192.168.42.1 as the address. Address to Name Lookups Using Nibble Format When looking up an address in nibble format, the address components are simply reversed, just as in IPv4, and ip6.arpa. is appended to the resulting name. For example, the following would provide reverse name lookup for a host with address 2001:db8::1. $ORIGIN 0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa. 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 14400 IN PTR host.example.com. The <acronym>BIND</acronym> 9 Lightweight Resolver The Lightweight Resolver Library Traditionally applications have been linked with a stub resolver library that sends recursive DNS queries to a local caching name server. IPv6 once introduced new complexity into the resolution process, such as following A6 chains and DNAME records, and simultaneous lookup of IPv4 and IPv6 addresses. Though most of the complexity was then removed, these are hard or impossible to implement in a traditional stub resolver. BIND 9 therefore can also provide resolution services to local clients using a combination of a lightweight resolver library and a resolver daemon process running on the local host. These communicate using a simple UDP-based protocol, the "lightweight resolver protocol" that is distinct from and simpler than the full DNS protocol. Running a Resolver Daemon To use the lightweight resolver interface, the system must run the resolver daemon lwresd or a local name server configured with a lwres statement. By default, applications using the lightweight resolver library will make UDP requests to the IPv4 loopback address (127.0.0.1) on port 921. The address can be overridden by lwserver lines in /etc/resolv.conf. The daemon currently only looks in the DNS, but in the future it may use other sources such as /etc/hosts, NIS, etc. The lwresd daemon is essentially a caching-only name server that responds to requests using the lightweight resolver protocol rather than the DNS protocol. Because it needs to run on each host, it is designed to require no or minimal configuration. Unless configured otherwise, it uses the name servers listed on nameserver lines in /etc/resolv.conf as forwarders, but is also capable of doing the resolution autonomously if none are specified. The lwresd daemon may also be configured with a named.conf style configuration file, in /etc/lwresd.conf by default. A name server may also be configured to act as a lightweight resolver daemon using the lwres statement in named.conf. <acronym>BIND</acronym> 9 Configuration Reference BIND 9 configuration is broadly similar to BIND 8; however, there are a few new areas of configuration, such as views. BIND 8 configuration files should work with few alterations in BIND 9, although more complex configurations should be reviewed to check if they can be more efficiently implemented using the new features found in BIND 9. BIND 4 configuration files can be converted to the new format using the shell script contrib/named-bootconf/named-bootconf.sh. Configuration File Elements Following is a list of elements used throughout the BIND configuration file documentation: acl_name The name of an address_match_list as defined by the acl statement. address_match_list A list of one or more ip_addr, ip_prefix, key_id, or acl_name elements, see . masters_list A named list of one or more ip_addr with optional key_id and/or ip_port. A masters_list may include other masters_lists. domain_name A quoted string which will be used as a DNS name, for example "my.test.domain". dotted_decimal One to four integers valued 0 through 255 separated by dots (`.'), such as 123, 45.67 or 89.123.45.67. ip4_addr An IPv4 address with exactly four elements in dotted_decimal notation. ip6_addr An IPv6 address, such as 2001:db8::1234. IPv6 scoped addresses that have ambiguity on their scope zones must be disambiguated by an appropriate zone ID with the percent character (`%') as delimiter. It is strongly recommended to use string zone names rather than numeric identifiers, in order to be robust against system configuration changes. However, since there is no standard mapping for such names and identifier values, currently only interface names as link identifiers are supported, assuming one-to-one mapping between interfaces and links. For example, a link-local address fe80::1 on the link attached to the interface ne0 can be specified as fe80::1%ne0. Note that on most systems link-local addresses always have the ambiguity, and need to be disambiguated. ip_addr An ip4_addr or ip6_addr. ip_port An IP port number. The number is limited to 0 through 65535, with values below 1024 typically restricted to use by processes running as root. In some cases, an asterisk (`*') character can be used as a placeholder to select a random high-numbered port. ip_prefix An IP network specified as an ip_addr, followed by a slash (`/') and then the number of bits in the netmask. Trailing zeros in a ip_addr may omitted. For example, 127/8 is the network 127.0.0.0 with netmask 255.0.0.0 and 1.2.3.0/28 is network 1.2.3.0 with netmask 255.255.255.240. When specifying a prefix involving a IPv6 scoped address the scope may be omitted. In that case the prefix will match packets from any scope. key_id A domain_name representing the name of a shared key, to be used for transaction security. key_list A list of one or more key_ids, separated by semicolons and ending with a semicolon. number A non-negative 32-bit integer (i.e., a number between 0 and 4294967295, inclusive). Its acceptable value might further be limited by the context in which it is used. path_name A quoted string which will be used as a pathname, such as zones/master/my.test.domain. port_list A list of an ip_port or a port range. A port range is specified in the form of range followed by two ip_ports, port_low and port_high, which represents port numbers from port_low through port_high, inclusive. port_low must not be larger than port_high. For example, range 1024 65535 represents ports from 1024 through 65535. In either case an asterisk (`*') character is not allowed as a valid ip_port. size_spec A number, the word unlimited, or the word default. An unlimited size_spec requests unlimited use, or the maximum available amount. A default size_spec uses the limit that was in force when the server was started. A number can optionally be followed by a scaling factor: K or k for kilobytes, M or m for megabytes, and G or g for gigabytes, which scale by 1024, 1024*1024, and 1024*1024*1024 respectively. The value must be representable as a 64-bit unsigned integer (0 to 18446744073709551615, inclusive). Using unlimited is the best way to safely set a really large number. yes_or_no Either yes or no. The words true and false are also accepted, as are the numbers 1 and 0. dialup_option One of yes, no, notify, notify-passive, refresh or passive. When used in a zone, notify-passive, refresh, and passive are restricted to slave and stub zones. Address Match Lists Syntax address_match_list = address_match_list_element ; address_match_list_element; ... address_match_list_element = ! (ip_address /length | key key_id | acl_name | { address_match_list } ) Definition and Usage Address match lists are primarily used to determine access control for various server operations. They are also used in the listen-on and sortlist statements. The elements which constitute an address match list can be any of the following: an IP address (IPv4 or IPv6) an IP prefix (in `/' notation) a key ID, as defined by the key statement the name of an address match list defined with the acl statement a nested address match list enclosed in braces Elements can be negated with a leading exclamation mark (`!'), and the match list names "any", "none", "localhost", and "localnets" are predefined. More information on those names can be found in the description of the acl statement. The addition of the key clause made the name of this syntactic element something of a misnomer, since security keys can be used to validate access without regard to a host or network address. Nonetheless, the term "address match list" is still used throughout the documentation. When a given IP address or prefix is compared to an address match list, the comparison takes place in approximately O(1) time. However, key comparisons require that the list of keys be traversed until a matching key is found, and therefore may be somewhat slower. The interpretation of a match depends on whether the list is being used for access control, defining listen-on ports, or in a sortlist, and whether the element was negated. When used as an access control list, a non-negated match allows access and a negated match denies access. If there is no match, access is denied. The clauses allow-notify, allow-recursion, allow-recursion-on, allow-query, allow-query-on, allow-query-cache, allow-query-cache-on, allow-transfer, allow-update, allow-update-forwarding, and blackhole all use address match lists. Similarly, the listen-on option will cause the server to refuse queries on any of the machine's addresses which do not match the list. Order of insertion is significant. If more than one element in an ACL is found to match a given IP address or prefix, preference will be given to the one that came first in the ACL definition. Because of this first-match behavior, an element that defines a subset of another element in the list should come before the broader element, regardless of whether either is negated. For example, in 1.2.3/24; ! 1.2.3.13; the 1.2.3.13 element is completely useless because the algorithm will match any lookup for 1.2.3.13 to the 1.2.3/24 element. Using ! 1.2.3.13; 1.2.3/24 fixes that problem by having 1.2.3.13 blocked by the negation, but all other 1.2.3.* hosts fall through. Comment Syntax The BIND 9 comment syntax allows for comments to appear anywhere that whitespace may appear in a BIND configuration file. To appeal to programmers of all kinds, they can be written in the C, C++, or shell/perl style. Syntax /* This is a BIND comment as in C */ // This is a BIND comment as in C++ # This is a BIND comment as in common UNIX shells and perl Definition and Usage Comments may appear anywhere that whitespace may appear in a BIND configuration file. C-style comments start with the two characters /* (slash, star) and end with */ (star, slash). Because they are completely delimited with these characters, they can be used to comment only a portion of a line or to span multiple lines. C-style comments cannot be nested. For example, the following is not valid because the entire comment ends with the first */: /* This is the start of a comment. This is still part of the comment. /* This is an incorrect attempt at nesting a comment. */ This is no longer in any comment. */ C++-style comments start with the two characters // (slash, slash) and continue to the end of the physical line. They cannot be continued across multiple physical lines; to have one logical comment span multiple lines, each line must use the // pair. For example: // This is the start of a comment. The next line // is a new comment, even though it is logically // part of the previous comment. Shell-style (or perl-style, if you prefer) comments start with the character # (number sign) and continue to the end of the physical line, as in C++ comments. For example: # This is the start of a comment. The next line # is a new comment, even though it is logically # part of the previous comment. You cannot use the semicolon (`;') character to start a comment such as you would in a zone file. The semicolon indicates the end of a configuration statement. Configuration File Grammar A BIND 9 configuration consists of statements and comments. Statements end with a semicolon. Statements and comments are the only elements that can appear without enclosing braces. Many statements contain a block of sub-statements, which are also terminated with a semicolon. The following statements are supported: acl defines a named IP address matching list, for access control and other uses. controls declares control channels to be used by the rndc utility. include includes a file. key specifies key information for use in authentication and authorization using TSIG. logging specifies what the server logs, and where the log messages are sent. lwres configures named to also act as a light-weight resolver daemon (lwresd). masters defines a named masters list for inclusion in stub and slave zone masters clauses. options controls global server configuration options and sets defaults for other statements. server sets certain configuration options on a per-server basis. statistics-channels declares communication channels to get access to named statistics. trusted-keys defines trusted DNSSEC keys. view defines a view. zone defines a zone. The logging and options statements may only occur once per configuration. <command>acl</command> Statement Grammar acl acl-name { address_match_list }; <command>acl</command> Statement Definition and Usage The acl statement assigns a symbolic name to an address match list. It gets its name from a primary use of address match lists: Access Control Lists (ACLs). Note that an address match list's name must be defined with acl before it can be used elsewhere; no forward references are allowed. The following ACLs are built-in: any Matches all hosts. none Matches no hosts. localhost Matches the IPv4 and IPv6 addresses of all network interfaces on the system. localnets Matches any host on an IPv4 or IPv6 network for which the system has an interface. Some systems do not provide a way to determine the prefix lengths of local IPv6 addresses. In such a case, localnets only matches the local IPv6 addresses, just like localhost. <command>controls</command> Statement Grammar controls { [ inet ( ip_addr | * ) [ port ip_port ] allow { address_match_list } keys { key_list }; ] [ inet ...; ] [ unix path perm number owner number group number keys { key_list }; ] [ unix ...; ] }; <command>controls</command> Statement Definition and Usage The controls statement declares control channels to be used by system administrators to control the operation of the name server. These control channels are used by the rndc utility to send commands to and retrieve non-DNS results from a name server. An inet control channel is a TCP socket listening at the specified ip_port on the specified ip_addr, which can be an IPv4 or IPv6 address. An ip_addr of * (asterisk) is interpreted as the IPv4 wildcard address; connections will be accepted on any of the system's IPv4 addresses. To listen on the IPv6 wildcard address, use an ip_addr of ::. If you will only use rndc on the local host, using the loopback address (127.0.0.1 or ::1) is recommended for maximum security. If no port is specified, port 953 is used. The asterisk "*" cannot be used for ip_port. The ability to issue commands over the control channel is restricted by the allow and keys clauses. Connections to the control channel are permitted based on the address_match_list. This is for simple IP address based filtering only; any key_id elements of the address_match_list are ignored. A unix control channel is a UNIX domain socket listening at the specified path in the file system. Access to the socket is specified by the perm, owner and group clauses. Note on some platforms (SunOS and Solaris) the permissions (perm) are applied to the parent directory as the permissions on the socket itself are ignored. The primary authorization mechanism of the command channel is the key_list, which contains a list of key_ids. Each key_id in the key_list is authorized to execute commands over the control channel. See in ) for information about configuring keys in rndc. If no controls statement is present, named will set up a default control channel listening on the loopback address 127.0.0.1 and its IPv6 counterpart ::1. In this case, and also when the controls statement is present but does not have a keys clause, named will attempt to load the command channel key from the file rndc.key in /etc (or whatever sysconfdir was specified as when BIND was built). To create a rndc.key file, run rndc-confgen -a. The rndc.key feature was created to ease the transition of systems from BIND 8, which did not have digital signatures on its command channel messages and thus did not have a keys clause. It makes it possible to use an existing BIND 8 configuration file in BIND 9 unchanged, and still have rndc work the same way ndc worked in BIND 8, simply by executing the command rndc-confgen -a after BIND 9 is installed. Since the rndc.key feature is only intended to allow the backward-compatible usage of BIND 8 configuration files, this feature does not have a high degree of configurability. You cannot easily change the key name or the size of the secret, so you should make a rndc.conf with your own key if you wish to change those things. The rndc.key file also has its permissions set such that only the owner of the file (the user that named is running as) can access it. If you desire greater flexibility in allowing other users to access rndc commands, then you need to create a rndc.conf file and make it group readable by a group that contains the users who should have access. To disable the command channel, use an empty controls statement: controls { };. <command>include</command> Statement Grammar include filename; <command>include</command> Statement Definition and Usage The include statement inserts the specified file at the point where the include statement is encountered. The include statement facilitates the administration of configuration files by permitting the reading or writing of some things but not others. For example, the statement could include private keys that are readable only by the name server. <command>key</command> Statement Grammar key key_id { algorithm string; secret string; }; <command>key</command> Statement Definition and Usage The key statement defines a shared secret key for use with TSIG (see ) or the command channel (see ). The key statement can occur at the top level of the configuration file or inside a view statement. Keys defined in top-level key statements can be used in all views. Keys intended for use in a controls statement (see ) must be defined at the top level. The key_id, also known as the key name, is a domain name uniquely identifying the key. It can be used in a server statement to cause requests sent to that server to be signed with this key, or in address match lists to verify that incoming requests have been signed with a key matching this name, algorithm, and secret. The algorithm_id is a string that specifies a security/authentication algorithm. Named supports hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384 and hmac-sha512 TSIG authentication. Truncated hashes are supported by appending the minimum number of required bits preceded by a dash, e.g. hmac-sha1-80. The secret_string is the secret to be used by the algorithm, and is treated as a base-64 encoded string. <command>logging</command> Statement Grammar logging { [ channel channel_name { ( file path_name [ versions ( number | unlimited ) ] [ size size spec ] | syslog syslog_facility | stderr | null ); [ severity ( | | | | | [ level ] | ); ] [ print-category or ; ] [ print-severity or ; ] [ print-time or ; ] }; ] [ category category_name { channel_name ; [ channel_name ; ... ] }; ] ... }; <command>logging</command> Statement Definition and Usage The logging statement configures a wide variety of logging options for the name server. Its channel phrase associates output methods, format options and severity levels with a name that can then be used with the category phrase to select how various classes of messages are logged. Only one logging statement is used to define as many channels and categories as are wanted. If there is no logging statement, the logging configuration will be: logging { category default { default_syslog; default_debug; }; category unmatched { null; }; }; In BIND 9, the logging configuration is only established when the entire configuration file has been parsed. In BIND 8, it was established as soon as the logging statement was parsed. When the server is starting up, all logging messages regarding syntax errors in the configuration file go to the default channels, or to standard error if the "" option was specified. The <command>channel</command> Phrase All log output goes to one or more channels; you can make as many of them as you want. Every channel definition must include a destination clause that says whether messages selected for the channel go to a file, to a particular syslog facility, to the standard error stream, or are discarded. It can optionally also limit the message severity level that will be accepted by the channel (the default is info), and whether to include a named-generated time stamp, the category name and/or severity level (the default is not to include any). The null destination clause causes all messages sent to the channel to be discarded; in that case, other options for the channel are meaningless. The file destination clause directs the channel to a disk file. It can include limitations both on how large the file is allowed to become, and how many versions of the file will be saved each time the file is opened. If you use the versions log file option, then named will retain that many backup versions of the file by renaming them when opening. For example, if you choose to keep three old versions of the file lamers.log, then just before it is opened lamers.log.1 is renamed to lamers.log.2, lamers.log.0 is renamed to lamers.log.1, and lamers.log is renamed to lamers.log.0. You can say versions unlimited to not limit the number of versions. If a size option is associated with the log file, then renaming is only done when the file being opened exceeds the indicated size. No backup versions are kept by default; any existing log file is simply appended. The size option for files is used to limit log growth. If the file ever exceeds the size, then named will stop writing to the file unless it has a versions option associated with it. If backup versions are kept, the files are rolled as described above and a new one begun. If there is no versions option, no more data will be written to the log until some out-of-band mechanism removes or truncates the log to less than the maximum size. The default behavior is not to limit the size of the file. Example usage of the size and versions options: channel an_example_channel { file "example.log" versions 3 size 20m; print-time yes; print-category yes; }; The syslog destination clause directs the channel to the system log. Its argument is a syslog facility as described in the syslog man page. Known facilities are kern, user, mail, daemon, auth, syslog, lpr, news, uucp, cron, authpriv, ftp, local0, local1, local2, local3, local4, local5, local6 and local7, however not all facilities are supported on all operating systems. How syslog will handle messages sent to this facility is described in the syslog.conf man page. If you have a system which uses a very old version of syslog that only uses two arguments to the openlog() function, then this clause is silently ignored. The severity clause works like syslog's "priorities", except that they can also be used if you are writing straight to a file rather than using syslog. Messages which are not at least of the severity level given will not be selected for the channel; messages of higher severity levels will be accepted. If you are using syslog, then the syslog.conf priorities will also determine what eventually passes through. For example, defining a channel facility and severity as daemon and debug but only logging daemon.warning via syslog.conf will cause messages of severity info and notice to be dropped. If the situation were reversed, with named writing messages of only warning or higher, then syslogd would print all messages it received from the channel. The stderr destination clause directs the channel to the server's standard error stream. This is intended for use when the server is running as a foreground process, for example when debugging a configuration. The server can supply extensive debugging information when it is in debugging mode. If the server's global debug level is greater than zero, then debugging mode will be active. The global debug level is set either by starting the named server with the flag followed by a positive integer, or by running rndc trace. The global debug level can be set to zero, and debugging mode turned off, by running rndc notrace. All debugging messages in the server have a debug level, and higher debug levels give more detailed output. Channels that specify a specific debug severity, for example: channel specific_debug_level { file "foo"; severity debug 3; }; will get debugging output of level 3 or less any time the server is in debugging mode, regardless of the global debugging level. Channels with dynamic severity use the server's global debug level to determine what messages to print. If print-time has been turned on, then the date and time will be logged. print-time may be specified for a syslog channel, but is usually pointless since syslog also logs the date and time. If print-category is requested, then the category of the message will be logged as well. Finally, if print-severity is on, then the severity level of the message will be logged. The print- options may be used in any combination, and will always be printed in the following order: time, category, severity. Here is an example where all three print- options are on: 28-Feb-2000 15:05:32.863 general: notice: running There are four predefined channels that are used for named's default logging as follows. How they are used is described in . channel default_syslog { syslog daemon; // send to syslog's daemon // facility severity info; // only send priority info // and higher }; channel default_debug { file "named.run"; // write to named.run in // the working directory // Note: stderr is used instead // of "named.run" // if the server is started // with the '-f' option. severity dynamic; // log at the server's // current debug level }; channel default_stderr { stderr; // writes to stderr severity info; // only send priority info // and higher }; channel null { null; // toss anything sent to // this channel }; The default_debug channel has the special property that it only produces output when the server's debug level is nonzero. It normally writes to a file called named.run in the server's working directory. For security reasons, when the "" command line option is used, the named.run file is created only after named has changed to the new UID, and any debug output generated while named is starting up and still running as root is discarded. If you need to capture this output, you must run the server with the "" option and redirect standard error to a file. Once a channel is defined, it cannot be redefined. Thus you cannot alter the built-in channels directly, but you can modify the default logging by pointing categories at channels you have defined. The <command>category</command> Phrase There are many categories, so you can send the logs you want to see wherever you want, without seeing logs you don't want. If you don't specify a list of channels for a category, then log messages in that category will be sent to the default category instead. If you don't specify a default category, the following "default default" is used: category default { default_syslog; default_debug; }; As an example, let's say you want to log security events to a file, but you also want keep the default logging behavior. You'd specify the following: channel my_security_channel { file "my_security_file"; severity info; }; category security { my_security_channel; default_syslog; default_debug; }; To discard all messages in a category, specify the null channel: category xfer-out { null; }; category notify { null; }; Following are the available categories and brief descriptions of the types of log information they contain. More categories may be added in future BIND releases. default The default category defines the logging options for those categories where no specific configuration has been defined. general The catch-all. Many things still aren't classified into categories, and they all end up here. database Messages relating to the databases used internally by the name server to store zone and cache data. security Approval and denial of requests. config Configuration file parsing and processing. resolver DNS resolution, such as the recursive lookups performed on behalf of clients by a caching name server. xfer-in Zone transfers the server is receiving. xfer-out Zone transfers the server is sending. notify The NOTIFY protocol. client Processing of client requests. unmatched Messages that named was unable to determine the class of or for which there was no matching view. A one line summary is also logged to the client category. This category is best sent to a file or stderr, by default it is sent to the null channel. network Network operations. update Dynamic updates. update-security Approval and denial of update requests. queries Specify where queries should be logged to. At startup, specifying the category queries will also enable query logging unless querylog option has been specified. The query log entry reports the client's IP address and port number, and the query name, class and type. It also reports whether the Recursion Desired flag was set (+ if set, - if not set), if the query was signed (S), EDNS was in use (E), if DO (DNSSEC Ok) was set (D), or if CD (Checking Disabled) was set (C). client 127.0.0.1#62536: query: www.example.com IN AAAA +SE client ::1#62537: query: www.example.net IN AAAA -SE query-errors Information about queries that resulted in some failure. dispatch Dispatching of incoming packets to the server modules where they are to be processed. dnssec DNSSEC and TSIG protocol processing. lame-servers Lame servers. These are misconfigurations in remote servers, discovered by BIND 9 when trying to query those servers during resolution. delegation-only Delegation only. Logs queries that have been forced to NXDOMAIN as the result of a delegation-only zone or a delegation-only in a hint or stub zone declaration. edns-disabled Log queries that have been forced to use plain DNS due to timeouts. This is often due to the remote servers not being RFC 1034 compliant (not always returning FORMERR or similar to EDNS queries and other extensions to the DNS when they are not understood). In other words, this is targeted at servers that fail to respond to DNS queries that they don't understand. Note: the log message can also be due to packet loss. Before reporting servers for non-RFC 1034 compliance they should be re-tested to determine the nature of the non-compliance. This testing should prevent or reduce the number of false-positive reports. Note: eventually named will have to stop treating such timeouts as due to RFC 1034 non compliance and start treating it as plain packet loss. Falsely classifying packet loss as due to RFC 1034 non compliance impacts on DNSSEC validation which requires EDNS for the DNSSEC records to be returned. The <command>query-errors</command> Category The query-errors category is specifically intended for debugging purposes: To identify why and how specific queries result in responses which indicate an error. Messages of this category are therefore only logged with debug levels. At the debug levels of 1 or higher, each response with the rcode of SERVFAIL is logged as follows: client 127.0.0.1#61502: query failed (SERVFAIL) for www.example.com/IN/AAAA at query.c:3880 This means an error resulting in SERVFAIL was detected at line 3880 of source file query.c. Log messages of this level will particularly help identify the cause of SERVFAIL for an authoritative server. At the debug levels of 2 or higher, detailed context information of recursive resolutions that resulted in SERVFAIL is logged. The log message will look like as follows: fetch completed at resolver.c:2970 for www.example.com/A in 30.000183: timed out/success [domain:example.com,referral:2,restart:7,qrysent:8,timeout:5,lame:0,neterr:0,badresp:1,adberr:0,findfail:0,valfail:0] The first part before the colon shows that a recursive resolution for AAAA records of www.example.com completed in 30.000183 seconds and the final result that led to the SERVFAIL was determined at line 2970 of source file resolver.c. The following part shows the detected final result and the latest result of DNSSEC validation. The latter is always success when no validation attempt is made. In this example, this query resulted in SERVFAIL probably because all name servers are down or unreachable, leading to a timeout in 30 seconds. DNSSEC validation was probably not attempted. The last part enclosed in square brackets shows statistics information collected for this particular resolution attempt. The domain field shows the deepest zone that the resolver reached; it is the zone where the error was finally detected. The meaning of the other fields is summarized in the following table. referral The number of referrals the resolver received throughout the resolution process. In the above example this is 2, which are most likely com and example.com. restart The number of cycles that the resolver tried remote servers at the domain zone. In each cycle the resolver sends one query (possibly resending it, depending on the response) to each known name server of the domain zone. qrysent The number of queries the resolver sent at the domain zone. timeout The number of timeouts since the resolver received the last response. lame The number of lame servers the resolver detected at the domain zone. A server is detected to be lame either by an invalid response or as a result of lookup in BIND9's address database (ADB), where lame servers are cached. neterr The number of erroneous results that the resolver encountered in sending queries at the domain zone. One common case is the remote server is unreachable and the resolver receives an ICMP unreachable error message. badresp The number of unexpected responses (other than lame) to queries sent by the resolver at the domain zone. adberr Failures in finding remote server addresses of the domain zone in the ADB. One common case of this is that the remote server's name does not have any address records. findfail Failures of resolving remote server addresses. This is a total number of failures throughout the resolution process. valfail Failures of DNSSEC validation. Validation failures are counted throughout the resolution process (not limited to the domain zone), but should only happen in domain. At the debug levels of 3 or higher, the same messages as those at the debug 1 level are logged for other errors than SERVFAIL. Note that negative responses such as NXDOMAIN are not regarded as errors here. At the debug levels of 4 or higher, the same messages as those at the debug 2 level are logged for other errors than SERVFAIL. Unlike the above case of level 3, messages are logged for negative responses. This is because any unexpected results can be difficult to debug in the recursion case. <command>lwres</command> Statement Grammar This is the grammar of the lwres statement in the named.conf file: lwres { listen-on { ip_addr port ip_port ; ip_addr port ip_port ; ... }; view view_name; search { domain_name ; domain_name ; ... }; ndots number; }; <command>lwres</command> Statement Definition and Usage The lwres statement configures the name server to also act as a lightweight resolver server. (See .) There may be multiple lwres statements configuring lightweight resolver servers with different properties. The listen-on statement specifies a list of addresses (and ports) that this instance of a lightweight resolver daemon should accept requests on. If no port is specified, port 921 is used. If this statement is omitted, requests will be accepted on 127.0.0.1, port 921. The view statement binds this instance of a lightweight resolver daemon to a view in the DNS namespace, so that the response will be constructed in the same manner as a normal DNS query matching this view. If this statement is omitted, the default view is used, and if there is no default view, an error is triggered. The search statement is equivalent to the search statement in /etc/resolv.conf. It provides a list of domains which are appended to relative names in queries. The ndots statement is equivalent to the ndots statement in /etc/resolv.conf. It indicates the minimum number of dots in a relative domain name that should result in an exact match lookup before search path elements are appended. <command>masters</command> Statement Grammar masters name port ip_port { ( masters_list | ip_addr port ip_port key key ) ;

This statement may appear only once in a configuration file. If there is no options statement, an options block with each option set to its default will be used. directory The working directory of the server. Any non-absolute pathnames in the configuration file will be taken as relative to this directory. The default location for most server output files (e.g. named.run) is this directory. If a directory is not specified, the working directory defaults to `.', the directory from which the server was started. The directory specified should be an absolute path. key-directory When performing dynamic update of secure zones, the directory where the public and private DNSSEC key files should be found, if different than the current working directory. The directory specified must be an absolute path. (Note that this option has no effect on the paths for files containing non-DNSSEC keys such as the rndc.key. named-xfer This option is obsolete. It was used in BIND 8 to specify the pathname to the named-xfer program. In BIND 9, no separate named-xfer program is needed; its functionality is built into the name server. tkey-gssapi-credential The security credential with which the server should authenticate keys requested by the GSS-TSIG protocol. Currently only Kerberos 5 authentication is available and the credential is a Kerberos principal which the server can acquire through the default system key file, normally /etc/krb5.keytab. Normally this principal is of the form "DNS/server.domain". To use GSS-TSIG, tkey-domain must also be set. tkey-domain The domain appended to the names of all shared keys generated with TKEY. When a client requests a TKEY exchange, it may or may not specify the desired name for the key. If present, the name of the shared key will be client specified part + tkey-domain. Otherwise, the name of the shared key will be random hex digits + tkey-domain. In most cases, the domainname should be the server's domain name, or an otherwise non-existent subdomain like "_tkey.domainname". If you are using GSS-TSIG, this variable must be defined. tkey-dhkey The Diffie-Hellman key used by the server to generate shared keys with clients using the Diffie-Hellman mode of TKEY. The server must be able to load the public and private keys from files in the working directory. In most cases, the keyname should be the server's host name. cache-file This is for testing only. Do not use. dump-file The pathname of the file the server dumps the database to when instructed to do so with rndc dumpdb. If not specified, the default is named_dump.db. memstatistics-file The pathname of the file the server writes memory usage statistics to on exit. If not specified, the default is named.memstats. pid-file The pathname of the file the server writes its process ID in. If not specified, the default is /var/run/named/named.pid. The PID file is used by programs that want to send signals to the running name server. Specifying pid-file none disables the use of a PID file — no file will be written and any existing one will be removed. Note that none is a keyword, not a filename, and therefore is not enclosed in double quotes. recursing-file The pathname of the file the server dumps the queries that are currently recursing when instructed to do so with rndc recursing. If not specified, the default is named.recursing. statistics-file The pathname of the file the server appends statistics to when instructed to do so using rndc stats. If not specified, the default is named.stats in the server's current directory. The format of the file is described in . port The UDP/TCP port number the server uses for receiving and sending DNS protocol traffic. The default is 53. This option is mainly intended for server testing; a server using a port other than 53 will not be able to communicate with the global DNS. random-device The source of entropy to be used by the server. Entropy is primarily needed for DNSSEC operations, such as TKEY transactions and dynamic update of signed zones. This options specifies the device (or file) from which to read entropy. If this is a file, operations requiring entropy will fail when the file has been exhausted. If not specified, the default value is /dev/random (or equivalent) when present, and none otherwise. The random-device option takes effect during the initial configuration load at server startup time and is ignored on subsequent reloads. preferred-glue If specified, the listed type (A or AAAA) will be emitted before other glue in the additional section of a query response. The default is not to prefer any type (NONE). root-delegation-only Turn on enforcement of delegation-only in TLDs (top level domains) and root zones with an optional exclude list. DS queries are expected to be made to and be answered by delegation only zones. Such queries and responses are treated as a exception to delegation-only processing and are not converted to NXDOMAIN responses provided a CNAME is not discovered at the query name. If a delegation only zone server also serves a child zone it is not always possible to determine whether a answer comes from the delegation only zone or the child zone. SOA NS and DNSKEY records are apex only records and a matching response that contains these records or DS is treated as coming from a child zone. RRSIG records are also examined to see if they are signed by a child zone or not. The authority section is also examined to see if there is evidence that the answer is from the child zone. Answers that are determined to be from a child zone are not converted to NXDOMAIN responses. Despite all these checks there is still a possibility of false negatives when a child zone is being served. Similarly false positives can arise from empty nodes (no records at the name) in the delegation only zone when the query type is not ANY. Note some TLDs are not delegation only (e.g. "DE", "LV", "US" and "MUSEUM"). This list is not exhaustive. options { root-delegation-only exclude { "de"; "lv"; "us"; "museum"; }; }; disable-algorithms Disable the specified DNSSEC algorithms at and below the specified name. Multiple disable-algorithms statements are allowed. Only the most specific will be applied. dnssec-lookaside When set, dnssec-lookaside provides the validator with an alternate method to validate DNSKEY records at the top of a zone. When a DNSKEY is at or below a domain specified by the deepest dnssec-lookaside, and the normal DNSSEC validation has left the key untrusted, the trust-anchor will be append to the key name and a DLV record will be looked up to see if it can validate the key. If the DLV record validates a DNSKEY (similarly to the way a DS record does) the DNSKEY RRset is deemed to be trusted. dnssec-must-be-secure Specify hierarchies which must be or may not be secure (signed and validated). If yes, then named will only accept answers if they are secure. If no, then normal DNSSEC validation applies allowing for insecure answers to be accepted. The specified domain must be under a trusted-key or dnssec-lookaside must be active. Boolean Options auth-nxdomain If yes, then the AA bit is always set on NXDOMAIN responses, even if the server is not actually authoritative. The default is no; this is a change from BIND 8. If you are using very old DNS software, you may need to set it to yes. deallocate-on-exit This option was used in BIND 8 to enable checking for memory leaks on exit. BIND 9 ignores the option and always performs the checks. memstatistics Write memory statistics to the file specified by memstatistics-file at exit. The default is no unless '-m record' is specified on the command line in which case it is yes. dialup If yes, then the server treats all zones as if they are doing zone transfers across a dial-on-demand dialup link, which can be brought up by traffic originating from this server. This has different effects according to zone type and concentrates the zone maintenance so that it all happens in a short interval, once every heartbeat-interval and hopefully during the one call. It also suppresses some of the normal zone maintenance traffic. The default is no. The dialup option may also be specified in the view and zone statements, in which case it overrides the global dialup option. If the zone is a master zone, then the server will send out a NOTIFY request to all the slaves (default). This should trigger the zone serial number check in the slave (providing it supports NOTIFY) allowing the slave to verify the zone while the connection is active. The set of servers to which NOTIFY is sent can be controlled by notify and also-notify. If the zone is a slave or stub zone, then the server will suppress the regular "zone up to date" (refresh) queries and only perform them when the heartbeat-interval expires in addition to sending NOTIFY requests. Finer control can be achieved by using notify which only sends NOTIFY messages, notify-passive which sends NOTIFY messages and suppresses the normal refresh queries, refresh which suppresses normal refresh processing and sends refresh queries when the heartbeat-interval expires, and passive which just disables normal refresh processing. dialup mode normal refresh heart-beat refresh heart-beat notify no (default) yes no no yes no yes yes notify yes no yes refresh no yes no passive no no no notify-passive no no yes Note that normal NOTIFY processing is not affected by dialup. fake-iquery In BIND 8, this option enabled simulating the obsolete DNS query type IQUERY. BIND 9 never does IQUERY simulation. fetch-glue This option is obsolete. In BIND 8, fetch-glue yes caused the server to attempt to fetch glue resource records it didn't have when constructing the additional data section of a response. This is now considered a bad idea and BIND 9 never does it. flush-zones-on-shutdown When the nameserver exits due receiving SIGTERM, flush or do not flush any pending zone writes. The default is flush-zones-on-shutdown no. has-old-clients This option was incorrectly implemented in BIND 8, and is ignored by BIND 9. To achieve the intended effect of has-old-clients yes, specify the two separate options auth-nxdomain yes and rfc2308-type1 no instead. host-statistics In BIND 8, this enables keeping of statistics for every host that the name server interacts with. Not implemented in BIND 9. maintain-ixfr-base This option is obsolete. It was used in BIND 8 to determine whether a transaction log was kept for Incremental Zone Transfer. BIND 9 maintains a transaction log whenever possible. If you need to disable outgoing incremental zone transfers, use provide-ixfr no. minimal-responses If yes, then when generating responses the server will only add records to the authority and additional data sections when they are required (e.g. delegations, negative responses). This may improve the performance of the server. The default is no. multiple-cnames This option was used in BIND 8 to allow a domain name to have multiple CNAME records in violation of the DNS standards. BIND 9.2 onwards always strictly enforces the CNAME rules both in master files and dynamic updates. notify If yes (the default), DNS NOTIFY messages are sent when a zone the server is authoritative for changes, see . The messages are sent to the servers listed in the zone's NS records (except the master server identified in the SOA MNAME field), and to any servers listed in the also-notify option. If master-only, notifies are only sent for master zones. If explicit, notifies are sent only to servers explicitly listed using also-notify. If no, no notifies are sent. The notify option may also be specified in the zone statement, in which case it overrides the options notify statement. It would only be necessary to turn off this option if it caused slaves to crash. notify-to-soa If yes do not check the nameservers in the NS RRset against the SOA MNAME. Normally a NOTIFY message is not sent to the SOA MNAME (SOA ORIGIN) as it is supposed to contain the name of the ultimate master. Sometimes, however, a slave is listed as the SOA MNAME in hidden master configurations and in that case you would want the ultimate master to still send NOTIFY messages to all the nameservers listed in the NS RRset. recursion If yes, and a DNS query requests recursion, then the server will attempt to do all the work required to answer the query. If recursion is off and the server does not already know the answer, it will return a referral response. The default is yes. Note that setting recursion no does not prevent clients from getting data from the server's cache; it only prevents new data from being cached as an effect of client queries. Caching may still occur as an effect the server's internal operation, such as NOTIFY address lookups. See also fetch-glue above. rfc2308-type1 Setting this to yes will cause the server to send NS records along with the SOA record for negative answers. The default is no. Not yet implemented in BIND 9. use-id-pool This option is obsolete. BIND 9 always allocates query IDs from a pool. zone-statistics If yes, the server will collect statistical data on all zones (unless specifically turned off on a per-zone basis by specifying zone-statistics no in the zone statement). These statistics may be accessed using rndc stats, which will dump them to the file listed in the statistics-file. See also . use-ixfr This option is obsolete. If you need to disable IXFR to a particular server or servers, see the information on the provide-ixfr option in . See also . provide-ixfr See the description of provide-ixfr in . request-ixfr See the description of request-ixfr in . treat-cr-as-space This option was used in BIND 8 to make the server treat carriage return ("\r") characters the same way as a space or tab character, to facilitate loading of zone files on a UNIX system that were generated on an NT or DOS machine. In BIND 9, both UNIX "\n" and NT/DOS "\r\n" newlines are always accepted, and the option is ignored. additional-from-auth additional-from-cache These options control the behavior of an authoritative server when answering queries which have additional data, or when following CNAME and DNAME chains. When both of these options are set to yes (the default) and a query is being answered from authoritative data (a zone configured into the server), the additional data section of the reply will be filled in using data from other authoritative zones and from the cache. In some situations this is undesirable, such as when there is concern over the correctness of the cache, or in servers where slave zones may be added and modified by untrusted third parties. Also, avoiding the search for this additional data will speed up server operations at the possible expense of additional queries to resolve what would otherwise be provided in the additional section. For example, if a query asks for an MX record for host foo.example.com, and the record found is "MX 10 mail.example.net", normally the address records (A and AAAA) for mail.example.net will be provided as well, if known, even though they are not in the example.com zone. Setting these options to no disables this behavior and makes the server only search for additional data in the zone it answers from. These options are intended for use in authoritative-only servers, or in authoritative-only views. Attempts to set them to no without also specifying recursion no will cause the server to ignore the options and log a warning message. Specifying additional-from-cache no actually disables the use of the cache not only for additional data lookups but also when looking up the answer. This is usually the desired behavior in an authoritative-only server where the correctness of the cached data is an issue. When a name server is non-recursively queried for a name that is not below the apex of any served zone, it normally answers with an "upwards referral" to the root servers or the servers of some other known parent of the query name. Since the data in an upwards referral comes from the cache, the server will not be able to provide upwards referrals when additional-from-cache no has been specified. Instead, it will respond to such queries with REFUSED. This should not cause any problems since upwards referrals are not required for the resolution process. match-mapped-addresses If yes, then an IPv4-mapped IPv6 address will match any address match list entries that match the corresponding IPv4 address. This option was introduced to work around a kernel quirk in some operating systems that causes IPv4 TCP connections, such as zone transfers, to be accepted on an IPv6 socket using mapped addresses. This caused address match lists designed for IPv4 to fail to match. However, named now solves this problem internally. The use of this option is discouraged. ixfr-from-differences When yes and the server loads a new version of a master zone from its zone file or receives a new version of a slave file by a non-incremental zone transfer, it will compare the new version to the previous one and calculate a set of differences. The differences are then logged in the zone's journal file such that the changes can be transmitted to downstream slaves as an incremental zone transfer. By allowing incremental zone transfers to be used for non-dynamic zones, this option saves bandwidth at the expense of increased CPU and memory consumption at the master. In particular, if the new version of a zone is completely different from the previous one, the set of differences will be of a size comparable to the combined size of the old and new zone version, and the server will need to temporarily allocate memory to hold this complete difference set. ixfr-from-differences also accepts master and slave at the view and options levels which causes ixfr-from-differences to be enabled for all master or slave zones respectively. It is off by default. multi-master This should be set when you have multiple masters for a zone and the addresses refer to different machines. If yes, named will not log when the serial number on the master is less than what named currently has. The default is no. dnssec-enable Enable DNSSEC support in named. Unless set to yes, named behaves as if it does not support DNSSEC. The default is yes. dnssec-validation Enable DNSSEC validation in named. Note dnssec-enable also needs to be set to yes to be effective. The default is yes. dnssec-accept-expired Accept expired signatures when verifying DNSSEC signatures. The default is no. Setting this option to "yes" leaves named vulnerable to replay attacks. querylog Specify whether query logging should be started when named starts. If querylog is not specified, then the query logging is determined by the presence of the logging category queries. check-names This option is used to restrict the character set and syntax of certain domain names in master files and/or DNS responses received from the network. The default varies according to usage area. For master zones the default is fail. For slave zones the default is warn. For answers received from the network (response) the default is ignore. The rules for legal hostnames and mail domains are derived from RFC 952 and RFC 821 as modified by RFC 1123. check-names applies to the owner names of A, AAAA and MX records. It also applies to the domain names in the RDATA of NS, SOA, MX, and SRV records. It also applies to the RDATA of PTR records where the owner name indicated that it is a reverse lookup of a hostname (the owner name ends in IN-ADDR.ARPA, IP6.ARPA, or IP6.INT). check-mx Check whether the MX record appears to refer to a IP address. The default is to warn. Other possible values are fail and ignore. check-wildcard This option is used to check for non-terminal wildcards. The use of non-terminal wildcards is almost always as a result of a failure to understand the wildcard matching algorithm (RFC 1034). This option affects master zones. The default (yes) is to check for non-terminal wildcards and issue a warning. check-integrity Perform post load zone integrity checks on master zones. This checks that MX and SRV records refer to address (A or AAAA) records and that glue address records exist for delegated zones. For MX and SRV records only in-zone hostnames are checked (for out-of-zone hostnames use named-checkzone). For NS records only names below top of zone are checked (for out-of-zone names and glue consistency checks use named-checkzone). The default is yes. check-mx-cname If check-integrity is set then fail, warn or ignore MX records that refer to CNAMES. The default is to warn. check-srv-cname If check-integrity is set then fail, warn or ignore SRV records that refer to CNAMES. The default is to warn. check-sibling When performing integrity checks, also check that sibling glue exists. The default is yes. zero-no-soa-ttl When returning authoritative negative responses to SOA queries set the TTL of the SOA record returned in the authority section to zero. The default is yes. zero-no-soa-ttl-cache When caching a negative response to a SOA query set the TTL to zero. The default is no. update-check-ksk When regenerating the RRSIGs following a UPDATE request to a secure zone, check the KSK flag on the DNSKEY RR to determine if this key should be used to generate the RRSIG. This flag is ignored if there are not DNSKEY RRs both with and without a KSK. The default is yes. try-tcp-refresh Try to refresh the zone using TCP if UDP queries fail. For BIND 8 compatibility, the default is yes. Forwarding The forwarding facility can be used to create a large site-wide cache on a few servers, reducing traffic over links to external name servers. It can also be used to allow queries by servers that do not have direct access to the Internet, but wish to look up exterior names anyway. Forwarding occurs only on those queries for which the server is not authoritative and does not have the answer in its cache. forward This option is only meaningful if the forwarders list is not empty. A value of first, the default, causes the server to query the forwarders first — and if that doesn't answer the question, the server will then look for the answer itself. If only is specified, the server will only query the forwarders. forwarders Specifies the IP addresses to be used for forwarding. The default is the empty list (no forwarding). Forwarding can also be configured on a per-domain basis, allowing for the global forwarding options to be overridden in a variety of ways. You can set particular domains to use different forwarders, or have a different forward only/first behavior, or not forward at all, see . Dual-stack Servers Dual-stack servers are used as servers of last resort to work around problems in reachability due the lack of support for either IPv4 or IPv6 on the host machine. dual-stack-servers Specifies host names or addresses of machines with access to both IPv4 and IPv6 transports. If a hostname is used, the server must be able to resolve the name using only the transport it has. If the machine is dual stacked, then the dual-stack-servers have no effect unless access to a transport has been disabled on the command line (e.g. named -4). Access Control Access to the server can be restricted based on the IP address of the requesting system. See for details on how to specify IP address lists. allow-notify Specifies which hosts are allowed to notify this server, a slave, of zone changes in addition to the zone masters. allow-notify may also be specified in the zone statement, in which case it overrides the options allow-notify statement. It is only meaningful for a slave zone. If not specified, the default is to process notify messages only from a zone's master. allow-query Specifies which hosts are allowed to ask ordinary DNS questions. allow-query may also be specified in the zone statement, in which case it overrides the options allow-query statement. If not specified, the default is to allow queries from all hosts. allow-query-cache is now used to specify access to the cache. allow-query-on Specifies which local addresses can accept ordinary DNS questions. This makes it possible, for instance, to allow queries on internal-facing interfaces but disallow them on external-facing ones, without necessarily knowing the internal network's addresses. allow-query-on may also be specified in the zone statement, in which case it overrides the options allow-query-on statement. If not specified, the default is to allow queries on all addresses. allow-query-cache is used to specify access to the cache. allow-query-cache Specifies which hosts are allowed to get answers from the cache. If allow-query-cache is not set then allow-recursion is used if set, otherwise allow-query is used if set unless recursion no; is set in which case none; is used, otherwise the default (localnets; localhost;) is used. allow-query-cache-on Specifies which local addresses can give answers from the cache. If not specified, the default is to allow cache queries on any address, localnets and localhost. allow-recursion Specifies which hosts are allowed to make recursive queries through this server. If allow-recursion is not set then allow-query-cache is used if set, otherwise allow-query is used if set, otherwise the default (localnets; localhost;) is used. allow-recursion-on Specifies which local addresses can accept recursive queries. If not specified, the default is to allow recursive queries on all addresses. allow-update Specifies which hosts are allowed to submit Dynamic DNS updates for master zones. The default is to deny updates from all hosts. Note that allowing updates based on the requestor's IP address is insecure; see for details. allow-update-forwarding Specifies which hosts are allowed to submit Dynamic DNS updates to slave zones to be forwarded to the master. The default is { none; }, which means that no update forwarding will be performed. To enable update forwarding, specify allow-update-forwarding { any; };. Specifying values other than { none; } or { any; } is usually counterproductive, since the responsibility for update access control should rest with the master server, not the slaves. Note that enabling the update forwarding feature on a slave server may expose master servers relying on insecure IP address based access control to attacks; see for more details. allow-v6-synthesis This option was introduced for the smooth transition from AAAA to A6 and from "nibble labels" to binary labels. However, since both A6 and binary labels were then deprecated, this option was also deprecated. It is now ignored with some warning messages. allow-transfer Specifies which hosts are allowed to receive zone transfers from the server. allow-transfer may also be specified in the zone statement, in which case it overrides the options allow-transfer statement. If not specified, the default is to allow transfers to all hosts. blackhole Specifies a list of addresses that the server will not accept queries from or use to resolve a query. Queries from these addresses will not be responded to. The default is none. Interfaces The interfaces and ports that the server will answer queries from may be specified using the listen-on option. listen-on takes an optional port and an address_match_list. The server will listen on all interfaces allowed by the address match list. If a port is not specified, port 53 will be used. Multiple listen-on statements are allowed. For example, listen-on { 5.6.7.8; }; listen-on port 1234 { !1.2.3.4; 1.2/16; }; will enable the name server on port 53 for the IP address 5.6.7.8, and on port 1234 of an address on the machine in net 1.2 that is not 1.2.3.4. If no listen-on is specified, the server will listen on port 53 on all IPv4 interfaces. The listen-on-v6 option is used to specify the interfaces and the ports on which the server will listen for incoming queries sent using IPv6. When { any; } is specified as the address_match_list for the listen-on-v6 option, the server does not bind a separate socket to each IPv6 interface address as it does for IPv4 if the operating system has enough API support for IPv6 (specifically if it conforms to RFC 3493 and RFC 3542). Instead, it listens on the IPv6 wildcard address. If the system only has incomplete API support for IPv6, however, the behavior is the same as that for IPv4. A list of particular IPv6 addresses can also be specified, in which case the server listens on a separate socket for each specified address, regardless of whether the desired API is supported by the system. Multiple listen-on-v6 options can be used. For example, listen-on-v6 { any; }; listen-on-v6 port 1234 { !2001:db8::/32; any; }; will enable the name server on port 53 for any IPv6 addresses (with a single wildcard socket), and on port 1234 of IPv6 addresses that is not in the prefix 2001:db8::/32 (with separate sockets for each matched address.) To make the server not listen on any IPv6 address, use listen-on-v6 { none; }; If no listen-on-v6 option is specified, the server will not listen on any IPv6 address unless -6 is specified when named is invoked. If -6 is specified then named will listen on port 53 on all IPv6 interfaces by default. Query Address If the server doesn't know the answer to a question, it will query other name servers. query-source specifies the address and port used for such queries. For queries sent over IPv6, there is a separate query-source-v6 option. If address is * (asterisk) or is omitted, a wildcard IP address (INADDR_ANY) will be used. If port is * or is omitted, a random port number from a pre-configured range is picked up and will be used for each query. The port range(s) is that specified in the use-v4-udp-ports (for IPv4) and use-v6-udp-ports (for IPv6) options, excluding the ranges specified in the avoid-v4-udp-ports and avoid-v6-udp-ports options, respectively. The defaults of the query-source and query-source-v6 options are: query-source address * port *; query-source-v6 address * port *; If use-v4-udp-ports or use-v6-udp-ports is unspecified, named will check if the operating system provides a programming interface to retrieve the system's default range for ephemeral ports. If such an interface is available, named will use the corresponding system default range; otherwise, it will use its own defaults: use-v4-udp-ports { range 1024 65535; }; use-v6-udp-ports { range 1024 65535; }; Note: make sure the ranges be sufficiently large for security. A desirable size depends on various parameters, but we generally recommend it contain at least 16384 ports (14 bits of entropy). Note also that the system's default range when used may be too small for this purpose, and that the range may even be changed while named is running; the new range will automatically be applied when named is reloaded. It is encouraged to configure use-v4-udp-ports and use-v6-udp-ports explicitly so that the ranges are sufficiently large and are reasonably independent from the ranges used by other applications. Note: the operational configuration where named runs may prohibit the use of some ports. For example, UNIX systems will not allow named running without a root privilege to use ports less than 1024. If such ports are included in the specified (or detected) set of query ports, the corresponding query attempts will fail, resulting in resolution failures or delay. It is therefore important to configure the set of ports that can be safely used in the expected operational environment. The defaults of the avoid-v4-udp-ports and avoid-v6-udp-ports options are: avoid-v4-udp-ports {}; avoid-v6-udp-ports {}; Note: BIND 9.5.0 introduced the use-queryport-pool option to support a pool of such random ports, but this option is now obsolete because reusing the same ports in the pool may not be sufficiently secure. For the same reason, it is generally strongly discouraged to specify a particular port for the query-source or query-source-v6 options; it implicitly disables the use of randomized port numbers. use-queryport-pool This option is obsolete. queryport-pool-ports This option is obsolete. queryport-pool-updateinterval This option is obsolete. The address specified in the query-source option is used for both UDP and TCP queries, but the port applies only to UDP queries. TCP queries always use a random unprivileged port. Solaris 2.5.1 and earlier does not support setting the source address for TCP sockets. See also transfer-source and notify-source. Zone Transfers BIND has mechanisms in place to facilitate zone transfers and set limits on the amount of load that transfers place on the system. The following options apply to zone transfers. also-notify Defines a global list of IP addresses of name servers that are also sent NOTIFY messages whenever a fresh copy of the zone is loaded, in addition to the servers listed in the zone's NS records. This helps to ensure that copies of the zones will quickly converge on stealth servers. Optionally, a port may be specified with each also-notify address to send the notify messages to a port other than the default of 53. If an also-notify list is given in a zone statement, it will override the options also-notify statement. When a zone notify statement is set to no, the IP addresses in the global also-notify list will not be sent NOTIFY messages for that zone. The default is the empty list (no global notification list). max-transfer-time-in Inbound zone transfers running longer than this many minutes will be terminated. The default is 120 minutes (2 hours). The maximum value is 28 days (40320 minutes). max-transfer-idle-in Inbound zone transfers making no progress in this many minutes will be terminated. The default is 60 minutes (1 hour). The maximum value is 28 days (40320 minutes). max-transfer-time-out Outbound zone transfers running longer than this many minutes will be terminated. The default is 120 minutes (2 hours). The maximum value is 28 days (40320 minutes). max-transfer-idle-out Outbound zone transfers making no progress in this many minutes will be terminated. The default is 60 minutes (1 hour). The maximum value is 28 days (40320 minutes). serial-query-rate Slave servers will periodically query master servers to find out if zone serial numbers have changed. Each such query uses a minute amount of the slave server's network bandwidth. To limit the amount of bandwidth used, BIND 9 limits the rate at which queries are sent. The value of the serial-query-rate option, an integer, is the maximum number of queries sent per second. The default is 20. In addition to controlling the rate SOA refresh queries are issued at serial-query-rate also controls the rate at which NOTIFY messages are sent from both master and slave zones. serial-queries In BIND 8, the serial-queries option set the maximum number of concurrent serial number queries allowed to be outstanding at any given time. BIND 9 does not limit the number of outstanding serial queries and ignores the serial-queries option. Instead, it limits the rate at which the queries are sent as defined using the serial-query-rate option. transfer-format Zone transfers can be sent using two different formats, one-answer and many-answers. The transfer-format option is used on the master server to determine which format it sends. one-answer uses one DNS message per resource record transferred. many-answers packs as many resource records as possible into a message. many-answers is more efficient, but is only supported by relatively new slave servers, such as BIND 9, BIND 8.x and BIND 4.9.5 onwards. The many-answers format is also supported by recent Microsoft Windows nameservers. The default is many-answers. transfer-format may be overridden on a per-server basis by using the server statement. transfers-in The maximum number of inbound zone transfers that can be running concurrently. The default value is 10. Increasing transfers-in may speed up the convergence of slave zones, but it also may increase the load on the local system. transfers-out The maximum number of outbound zone transfers that can be running concurrently. Zone transfer requests in excess of the limit will be refused. The default value is 10. transfers-per-ns The maximum number of inbound zone transfers that can be concurrently transferring from a given remote name server. The default value is 2. Increasing transfers-per-ns may speed up the convergence of slave zones, but it also may increase the load on the remote name server. transfers-per-ns may be overridden on a per-server basis by using the transfers phrase of the server statement. transfer-source transfer-source determines which local address will be bound to IPv4 TCP connections used to fetch zones transferred inbound by the server. It also determines the source IPv4 address, and optionally the UDP port, used for the refresh queries and forwarded dynamic updates. If not set, it defaults to a system controlled value which will usually be the address of the interface "closest to" the remote end. This address must appear in the remote end's allow-transfer option for the zone being transferred, if one is specified. This statement sets the transfer-source for all zones, but can be overridden on a per-view or per-zone basis by including a transfer-source statement within the view or zone block in the configuration file. Solaris 2.5.1 and earlier does not support setting the source address for TCP sockets. transfer-source-v6 The same as transfer-source, except zone transfers are performed using IPv6. alt-transfer-source An alternate transfer source if the one listed in transfer-source fails and use-alt-transfer-source is set. If you do not wish the alternate transfer source to be used, you should set use-alt-transfer-source appropriately and you should not depend upon getting an answer back to the first refresh query. alt-transfer-source-v6 An alternate transfer source if the one listed in transfer-source-v6 fails and use-alt-transfer-source is set. use-alt-transfer-source Use the alternate transfer sources or not. If views are specified this defaults to no otherwise it defaults to yes (for BIND 8 compatibility). notify-source notify-source determines which local source address, and optionally UDP port, will be used to send NOTIFY messages. This address must appear in the slave server's masters zone clause or in an allow-notify clause. This statement sets the notify-source for all zones, but can be overridden on a per-zone or per-view basis by including a notify-source statement within the zone or view block in the configuration file. Solaris 2.5.1 and earlier does not support setting the source address for TCP sockets. notify-source-v6 Like notify-source, but applies to notify messages sent to IPv6 addresses. UDP Port Lists use-v4-udp-ports, avoid-v4-udp-ports, use-v6-udp-ports, and avoid-v6-udp-ports specify a list of IPv4 and IPv6 UDP ports that will be used or not used as source ports for UDP messages. See about how the available ports are determined. For example, with the following configuration use-v6-udp-ports { range 32768 65535; }; avoid-v6-udp-ports { 40000; range 50000 60000; }; UDP ports of IPv6 messages sent from named will be in one of the following ranges: 32768 to 39999, 40001 to 49999, and 60001 to 65535. avoid-v4-udp-ports and avoid-v6-udp-ports can be used to prevent named from choosing as its random source port a port that is blocked by your firewall or a port that is used by other applications; if a query went out with a source port blocked by a firewall, the answer would not get by the firewall and the name server would have to query again. Note: the desired range can also be represented only with use-v4-udp-ports and use-v6-udp-ports, and the avoid- options are redundant in that sense; they are provided for backward compatibility and to possibly simplify the port specification. Operating System Resource Limits The server's usage of many system resources can be limited. Scaled values are allowed when specifying resource limits. For example, 1G can be used instead of 1073741824 to specify a limit of one gigabyte. unlimited requests unlimited use, or the maximum available amount. default uses the limit that was in force when the server was started. See the description of size_spec in . The following options set operating system resource limits for the name server process. Some operating systems don't support some or any of the limits. On such systems, a warning will be issued if the unsupported limit is used. coresize The maximum size of a core dump. The default is default. datasize The maximum amount of data memory the server may use. The default is default. This is a hard limit on server memory usage. If the server attempts to allocate memory in excess of this limit, the allocation will fail, which may in turn leave the server unable to perform DNS service. Therefore, this option is rarely useful as a way of limiting the amount of memory used by the server, but it can be used to raise an operating system data size limit that is too small by default. If you wish to limit the amount of memory used by the server, use the max-cache-size and recursive-clients options instead. files The maximum number of files the server may have open concurrently. The default is unlimited. stacksize The maximum amount of stack memory the server may use. The default is default. Server Resource Limits The following options set limits on the server's resource consumption that are enforced internally by the server rather than the operating system. max-ixfr-log-size This option is obsolete; it is accepted and ignored for BIND 8 compatibility. The option max-journal-size performs a similar function in BIND 9. max-journal-size Sets a maximum size for each journal file (see ). When the journal file approaches the specified size, some of the oldest transactions in the journal will be automatically removed. The default is unlimited. This may also be set on a per-zone basis. host-statistics-max In BIND 8, specifies the maximum number of host statistics entries to be kept. Not implemented in BIND 9. recursive-clients The maximum number of simultaneous recursive lookups the server will perform on behalf of clients. The default is 1000. Because each recursing client uses a fair bit of memory, on the order of 20 kilobytes, the value of the recursive-clients option may have to be decreased on hosts with limited memory. tcp-clients The maximum number of simultaneous client TCP connections that the server will accept. The default is 100. reserved-sockets The number of file descriptors reserved for TCP, stdio, etc. This needs to be big enough to cover the number of interfaces named listens on, tcp-clients as well as to provide room for outgoing TCP queries and incoming zone transfers. The default is 512. The minimum value is 128 and the maximum value is 128 less than maxsockets (-S). This option may be removed in the future. This option has little effect on Windows. max-cache-size The maximum amount of memory to use for the server's cache, in bytes. When the amount of data in the cache reaches this limit, the server will cause records to expire prematurely based on an LRU based strategy so that the limit is not exceeded. A value of 0 is special, meaning that records are purged from the cache only when their TTLs expire. Another special keyword unlimited means the maximum value of 32-bit unsigned integers (0xffffffff), which may not have the same effect as 0 on machines that support more than 32 bits of memory space. Any positive values less than 2MB will be ignored reset to 2MB. In a server with multiple views, the limit applies separately to the cache of each view. The default is 0. tcp-listen-queue The listen queue depth. The default and minimum is 3. If the kernel supports the accept filter "dataready" this also controls how many TCP connections that will be queued in kernel space waiting for some data before being passed to accept. Values less than 3 will be silently raised. Periodic Task Intervals cleaning-interval This interval is effectively obsolete. Previously, the server would remove expired resource records from the cache every cleaning-interval minutes. BIND 9 now manages cache memory in a more sophisticated manner and does not rely on the periodic cleaning any more. Specifying this option therefore has no effect on the server's behavior. heartbeat-interval The server will perform zone maintenance tasks for all zones marked as dialup whenever this interval expires. The default is 60 minutes. Reasonable values are up to 1 day (1440 minutes). The maximum value is 28 days (40320 minutes). If set to 0, no zone maintenance for these zones will occur. interface-interval The server will scan the network interface list every interface-interval minutes. The default is 60 minutes. The maximum value is 28 days (40320 minutes). If set to 0, interface scanning will only occur when the configuration file is loaded. After the scan, the server will begin listening for queries on any newly discovered interfaces (provided they are allowed by the listen-on configuration), and will stop listening on interfaces that have gone away. statistics-interval Name server statistics will be logged every statistics-interval minutes. The default is 60. The maximum value is 28 days (40320 minutes). If set to 0, no statistics will be logged. Not yet implemented in BIND 9. Topology All other things being equal, when the server chooses a name server to query from a list of name servers, it prefers the one that is topologically closest to itself. The topology statement takes an address_match_list and interprets it in a special way. Each top-level list element is assigned a distance. Non-negated elements get a distance based on their position in the list, where the closer the match is to the start of the list, the shorter the distance is between it and the server. A negated match will be assigned the maximum distance from the server. If there is no match, the address will get a distance which is further than any non-negated list element, and closer than any negated element. For example, topology { 10/8; !1.2.3/24; { 1.2/16; 3/8; }; }; will prefer servers on network 10 the most, followed by hosts on network 1.2.0.0 (netmask 255.255.0.0) and network 3, with the exception of hosts on network 1.2.3 (netmask 255.255.255.0), which is preferred least of all. The default topology is topology { localhost; localnets; }; The topology option is not implemented in BIND 9. The <command>sortlist</command> Statement The response to a DNS query may consist of multiple resource records (RRs) forming a resource records set (RRset). The name server will normally return the RRs within the RRset in an indeterminate order (but see the rrset-order statement in ). The client resolver code should rearrange the RRs as appropriate, that is, using any addresses on the local net in preference to other addresses. However, not all resolvers can do this or are correctly configured. When a client is using a local server, the sorting can be performed in the server, based on the client's address. This only requires configuring the name servers, not all the clients. The sortlist statement (see below) takes an address_match_list and interprets it even more specifically than the topology statement does (). Each top level statement in the sortlist must itself be an explicit address_match_list with one or two elements. The first element (which may be an IP address, an IP prefix, an ACL name or a nested address_match_list) of each top level list is checked against the source address of the query until a match is found. Once the source address of the query has been matched, if the top level statement contains only one element, the actual primitive element that matched the source address is used to select the address in the response to move to the beginning of the response. If the statement is a list of two elements, then the second element is treated the same as the address_match_list in a topology statement. Each top level element is assigned a distance and the address in the response with the minimum distance is moved to the beginning of the response. In the following example, any queries received from any of the addresses of the host itself will get responses preferring addresses on any of the locally connected networks. Next most preferred are addresses on the 192.168.1/24 network, and after that either the 192.168.2/24 or 192.168.3/24 network with no preference shown between these two networks. Queries received from a host on the 192.168.1/24 network will prefer other addresses on that network to the 192.168.2/24 and 192.168.3/24 networks. Queries received from a host on the 192.168.4/24 or the 192.168.5/24 network will only prefer other addresses on their directly connected networks. sortlist { { localhost; // IF the local host { localnets; // THEN first fit on the 192.168.1/24; // following nets { 192.168.2/24; 192.168.3/24; }; }; }; { 192.168.1/24; // IF on class C 192.168.1 { 192.168.1/24; // THEN use .1, or .2 or .3 { 192.168.2/24; 192.168.3/24; }; }; }; { 192.168.2/24; // IF on class C 192.168.2 { 192.168.2/24; // THEN use .2, or .1 or .3 { 192.168.1/24; 192.168.3/24; }; }; }; { 192.168.3/24; // IF on class C 192.168.3 { 192.168.3/24; // THEN use .3, or .1 or .2 { 192.168.1/24; 192.168.2/24; }; }; }; { { 192.168.4/24; 192.168.5/24; }; // if .4 or .5, prefer that net }; }; The following example will give reasonable behavior for the local host and hosts on directly connected networks. It is similar to the behavior of the address sort in BIND 4.9.x. Responses sent to queries from the local host will favor any of the directly connected networks. Responses sent to queries from any other hosts on a directly connected network will prefer addresses on that same network. Responses to other queries will not be sorted. sortlist { { localhost; localnets; }; { localnets; }; }; RRset Ordering When multiple records are returned in an answer it may be useful to configure the order of the records placed into the response. The rrset-order statement permits configuration of the ordering of the records in a multiple record response. See also the sortlist statement, . An order_spec is defined as follows: class class_name type type_name name "domain_name" order ordering If no class is specified, the default is ANY. If no type is specified, the default is ANY. If no name is specified, the default is "*" (asterisk). The legal values for ordering are: fixed Records are returned in the order they are defined in the zone file. random Records are returned in some random order. cyclic Records are returned in a cyclic round-robin order. If BIND is configured with the "--enable-fixed-rrset" option at compile time, then the initial ordering of the RRset will match the one specified in the zone file. For example: rrset-order { class IN type A name "host.example.com" order random; order cyclic; }; will cause any responses for type A records in class IN that have "host.example.com" as a suffix, to always be returned in random order. All other records are returned in cyclic order. If multiple rrset-order statements appear, they are not combined — the last one applies. In this release of BIND 9, the rrset-order statement does not support "fixed" ordering by default. Fixed ordering can be enabled at compile time by specifying "--enable-fixed-rrset" on the "configure" command line. Tuning lame-ttl Sets the number of seconds to cache a lame server indication. 0 disables caching. (This is NOT recommended.) The default is 600 (10 minutes) and the maximum value is 1800 (30 minutes). Lame-ttl also controls the amount of time DNSSEC validation failures are cached. There is a minimum of 30 seconds applied to bad cache entries if the lame-ttl is set to less than 30 seconds. max-ncache-ttl To reduce network traffic and increase performance, the server stores negative answers. max-ncache-ttl is used to set a maximum retention time for these answers in the server in seconds. The default max-ncache-ttl is 10800 seconds (3 hours). max-ncache-ttl cannot exceed 7 days and will be silently truncated to 7 days if set to a greater value. max-cache-ttl Sets the maximum time for which the server will cache ordinary (positive) answers. The default is one week (7 days). A value of zero may cause all queries to return SERVFAIL, because of lost caches of intermediate RRsets (such as NS and glue AAAA/A records) in the resolution process. min-roots The minimum number of root servers that is required for a request for the root servers to be accepted. The default is 2. Not implemented in BIND 9. sig-validity-interval Specifies the number of days into the future when DNSSEC signatures automatically generated as a result of dynamic updates () will expire. There is a optional second field which specifies how long before expiry that the signatures will be regenerated. If not specified, the signatures will be regenerated at 1/4 of base interval. The second field is specified in days if the base interval is greater than 7 days otherwise it is specified in hours. The default base interval is 30 days giving a re-signing interval of 7 1/2 days. The maximum values are 10 years (3660 days). The signature inception time is unconditionally set to one hour before the current time to allow for a limited amount of clock skew. The sig-validity-interval should be, at least, several multiples of the SOA expire interval to allow for reasonable interaction between the various timer and expiry dates. sig-signing-nodes Specify the maximum number of nodes to be examined in each quantum when signing a zone with a new DNSKEY. The default is 100. sig-signing-signatures Specify a threshold number of signatures that will terminate processing a quantum when signing a zone with a new DNSKEY. The default is 10. sig-signing-type Specify a private RDATA type to be used when generating key signing records. The default is 65534. It is expected that this parameter may be removed in a future version once there is a standard type. min-refresh-time max-refresh-time min-retry-time max-retry-time These options control the server's behavior on refreshing a zone (querying for SOA changes) or retrying failed transfers. Usually the SOA values for the zone are used, but these values are set by the master, giving slave server administrators little control over their contents. These options allow the administrator to set a minimum and maximum refresh and retry time either per-zone, per-view, or globally. These options are valid for slave and stub zones, and clamp the SOA refresh and retry times to the specified values. The following defaults apply. min-refresh-time 300 seconds, max-refresh-time 2419200 seconds (4 weeks), min-retry-time 500 seconds, and max-retry-time 1209600 seconds (2 weeks). edns-udp-size Sets the advertised EDNS UDP buffer size in bytes to control the size of packets received. Valid values are 512 to 4096 (values outside this range will be silently adjusted). The default value is 4096. The usual reason for setting edns-udp-size to a non-default value is to get UDP answers to pass through broken firewalls that block fragmented packets and/or block UDP packets that are greater than 512 bytes. max-udp-size Sets the maximum EDNS UDP message size named will send in bytes. Valid values are 512 to 4096 (values outside this range will be silently adjusted). The default value is 4096. The usual reason for setting max-udp-size to a non-default value is to get UDP answers to pass through broken firewalls that block fragmented packets and/or block UDP packets that are greater than 512 bytes. This is independent of the advertised receive buffer (edns-udp-size). masterfile-format Specifies the file format of zone files (see ). The default value is text, which is the standard textual representation. Files in other formats than text are typically expected to be generated by the named-compilezone tool. Note that when a zone file in a different format than text is loaded, named may omit some of the checks which would be performed for a file in the text format. In particular, check-names checks do not apply for the raw format. This means a zone file in the raw format must be generated with the same check level as that specified in the named configuration file. This statement sets the masterfile-format for all zones, but can be overridden on a per-zone or per-view basis by including a masterfile-format statement within the zone or view block in the configuration file. clients-per-query max-clients-per-query These set the initial value (minimum) and maximum number of recursive simultaneous clients for any given query (<qname,qtype,qclass>) that the server will accept before dropping additional clients. named will attempt to self tune this value and changes will be logged. The default values are 10 and 100. This value should reflect how many queries come in for a given name in the time it takes to resolve that name. If the number of queries exceed this value, named will assume that it is dealing with a non-responsive zone and will drop additional queries. If it gets a response after dropping queries, it will raise the estimate. The estimate will then be lowered in 20 minutes if it has remained unchanged. If clients-per-query is set to zero, then there is no limit on the number of clients per query and no queries will be dropped. If max-clients-per-query is set to zero, then there is no upper bound other than imposed by recursive-clients. notify-delay The delay, in seconds, between sending sets of notify messages for a zone. The default is five (5) seconds. The overall rate that NOTIFY messages are sent for all zones is controlled by serial-query-rate. Built-in server information zones The server provides some helpful diagnostic information through a number of built-in zones under the pseudo-top-level-domain bind in the CHAOS class. These zones are part of a built-in view (see ) of class CHAOS which is separate from the default view of class IN; therefore, any global server options such as allow-query do not apply the these zones. If you feel the need to disable these zones, use the options below, or hide the built-in CHAOS view by defining an explicit view of class CHAOS that matches all clients. version The version the server should report via a query of the name version.bind with type TXT, class CHAOS. The default is the real version number of this server. Specifying version none disables processing of the queries. hostname The hostname the server should report via a query of the name hostname.bind with type TXT, class CHAOS. This defaults to the hostname of the machine hosting the name server as found by the gethostname() function. The primary purpose of such queries is to identify which of a group of anycast servers is actually answering your queries. Specifying hostname none; disables processing of the queries. server-id The ID the server should report when receiving a Name Server Identifier (NSID) query, or a query of the name ID.SERVER with type TXT, class CHAOS. The primary purpose of such queries is to identify which of a group of anycast servers is actually answering your queries. Specifying server-id none; disables processing of the queries. Specifying server-id hostname; will cause named to use the hostname as found by the gethostname() function. The default server-id is none. Built-in Empty Zones Named has some built-in empty zones (SOA and NS records only). These are for zones that should normally be answered locally and which queries should not be sent to the Internet's root servers. The official servers which cover these namespaces return NXDOMAIN responses to these queries. In particular, these cover the reverse namespaces for addresses from RFC 1918, RFC 4193, and RFC 5737. They also include the reverse namespace for IPv6 local address (locally assigned), IPv6 link local addresses, the IPv6 loopback address and the IPv6 unknown address. Named will attempt to determine if a built-in zone already exists or is active (covered by a forward-only forwarding declaration) and will not create a empty zone in that case. The current list of empty zones is: 10.IN-ADDR.ARPA 16.172.IN-ADDR.ARPA 17.172.IN-ADDR.ARPA 18.172.IN-ADDR.ARPA 19.172.IN-ADDR.ARPA 20.172.IN-ADDR.ARPA 21.172.IN-ADDR.ARPA 22.172.IN-ADDR.ARPA 23.172.IN-ADDR.ARPA 24.172.IN-ADDR.ARPA 25.172.IN-ADDR.ARPA 26.172.IN-ADDR.ARPA 27.172.IN-ADDR.ARPA 28.172.IN-ADDR.ARPA 29.172.IN-ADDR.ARPA 30.172.IN-ADDR.ARPA 31.172.IN-ADDR.ARPA 168.192.IN-ADDR.ARPA 0.IN-ADDR.ARPA 127.IN-ADDR.ARPA 254.169.IN-ADDR.ARPA 2.0.192.IN-ADDR.ARPA 100.51.198.IN-ADDR.ARPA 113.0.203.IN-ADDR.ARPA 255.255.255.255.IN-ADDR.ARPA 0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA 8.B.D.0.1.0.0.2.IP6.ARPA D.F.IP6.ARPA 8.E.F.IP6.ARPA 9.E.F.IP6.ARPA A.E.F.IP6.ARPA B.E.F.IP6.ARPA Empty zones are settable at the view level and only apply to views of class IN. Disabled empty zones are only inherited from options if there are no disabled empty zones specified at the view level. To override the options list of disabled zones, you can disable the root zone at the view level, for example: disable-empty-zone "."; If you are using the address ranges covered here, you should already have reverse zones covering the addresses you use. In practice this appears to not be the case with many queries being made to the infrastructure servers for names in these spaces. So many in fact that sacrificial servers were needed to be deployed to channel the query load away from the infrastructure servers. The real parent servers for these zones should disable all empty zone under the parent zone they serve. For the real root servers, this is all built-in empty zones. This will enable them to return referrals to deeper in the tree. empty-server Specify what server name will appear in the returned SOA record for empty zones. If none is specified, then the zone's name will be used. empty-contact Specify what contact name will appear in the returned SOA record for empty zones. If none is specified, then "." will be used. empty-zones-enable Enable or disable all empty zones. By default, they are enabled. disable-empty-zone Disable individual empty zones. By default, none are disabled. This option can be specified multiple times. Additional Section Caching The additional section cache, also called acache, is an internal cache to improve the response performance of BIND 9. When additional section caching is enabled, BIND 9 will cache an internal short-cut to the additional section content for each answer RR. Note that acache is an internal caching mechanism of BIND 9, and is not related to the DNS caching server function. Additional section caching does not change the response content (except the RRsets ordering of the additional section, see below), but can improve the response performance significantly. It is particularly effective when BIND 9 acts as an authoritative server for a zone that has many delegations with many glue RRs. In order to obtain the maximum performance improvement from additional section caching, setting additional-from-cache to no is recommended, since the current implementation of acache does not short-cut of additional section information from the DNS cache data. One obvious disadvantage of acache is that it requires much more memory for the internal cached data. Thus, if the response performance does not matter and memory consumption is much more critical, the acache mechanism can be disabled by setting acache-enable to no. It is also possible to specify the upper limit of memory consumption for acache by using max-acache-size. Additional section caching also has a minor effect on the RRset ordering in the additional section. Without acache, cyclic order is effective for the additional section as well as the answer and authority sections. However, additional section caching fixes the ordering when it first caches an RRset for the additional section, and the same ordering will be kept in succeeding responses, regardless of the setting of rrset-order. The effect of this should be minor, however, since an RRset in the additional section typically only contains a small number of RRs (and in many cases it only contains a single RR), in which case the ordering does not matter much. The following is a summary of options related to acache. acache-enable If yes, additional section caching is enabled. The default value is no. acache-cleaning-interval The server will remove stale cache entries, based on an LRU based algorithm, every acache-cleaning-interval minutes. The default is 60 minutes. If set to 0, no periodic cleaning will occur. max-acache-size The maximum amount of memory in bytes to use for the server's acache. When the amount of data in the acache reaches this limit, the server will clean more aggressively so that the limit is not exceeded. In a server with multiple views, the limit applies separately to the acache of each view. The default is 16M. <command>server</command> Statement Grammar server ip_addr[/prefixlen] { bogus yes_or_no ; provide-ixfr yes_or_no ; request-ixfr yes_or_no ; edns yes_or_no ; edns-udp-size number ; max-udp-size number ; transfers number ; transfer-format ( one-answer | many-answers ) ; ] keys { string ; string ; ... } ; transfer-source (ip4_addr | *) port ip_port ; transfer-source-v6 (ip6_addr | *) port ip_port ; notify-source (ip4_addr | *) port ip_port ; notify-source-v6 (ip6_addr | *) port ip_port ; query-source address ( ip_addr | * ) port ( ip_port | * ) ; query-source-v6 address ( ip_addr | * ) port ( ip_port | * ) ; use-queryport-pool yes_or_no; queryport-pool-ports number; queryport-pool-updateinterval number; }; <command>server</command> Statement Definition and Usage The server statement defines characteristics to be associated with a remote name server. If a prefix length is specified, then a range of servers is covered. Only the most specific server clause applies regardless of the order in named.conf. The server statement can occur at the top level of the configuration file or inside a view statement. If a view statement contains one or more server statements, only those apply to the view and any top-level ones are ignored. If a view contains no server statements, any top-level server statements are used as defaults. If you discover that a remote server is giving out bad data, marking it as bogus will prevent further queries to it. The default value of bogus is no. The provide-ixfr clause determines whether the local server, acting as master, will respond with an incremental zone transfer when the given remote server, a slave, requests it. If set to yes, incremental transfer will be provided whenever possible. If set to no, all transfers to the remote server will be non-incremental. If not set, the value of the provide-ixfr option in the view or global options block is used as a default. The request-ixfr clause determines whether the local server, acting as a slave, will request incremental zone transfers from the given remote server, a master. If not set, the value of the request-ixfr option in the view or global options block is used as a default. IXFR requests to servers that do not support IXFR will automatically fall back to AXFR. Therefore, there is no need to manually list which servers support IXFR and which ones do not; the global default of yes should always work. The purpose of the provide-ixfr and request-ixfr clauses is to make it possible to disable the use of IXFR even when both master and slave claim to support it, for example if one of the servers is buggy and crashes or corrupts data when IXFR is used. The edns clause determines whether the local server will attempt to use EDNS when communicating with the remote server. The default is yes. The edns-udp-size option sets the EDNS UDP size that is advertised by named when querying the remote server. Valid values are 512 to 4096 bytes (values outside this range will be silently adjusted). This option is useful when you wish to advertises a different value to this server than the value you advertise globally, for example, when there is a firewall at the remote site that is blocking large replies. The max-udp-size option sets the maximum EDNS UDP message size named will send. Valid values are 512 to 4096 bytes (values outside this range will be silently adjusted). This option is useful when you know that there is a firewall that is blocking large replies from named. The server supports two zone transfer methods. The first, one-answer, uses one DNS message per resource record transferred. many-answers packs as many resource records as possible into a message. many-answers is more efficient, but is only known to be understood by BIND 9, BIND 8.x, and patched versions of BIND 4.9.5. You can specify which method to use for a server with the transfer-format option. If transfer-format is not specified, the transfer-format specified by the options statement will be used. transfers is used to limit the number of concurrent inbound zone transfers from the specified server. If no transfers clause is specified, the limit is set according to the transfers-per-ns option. The keys clause identifies a key_id defined by the key statement, to be used for transaction security (TSIG, ) when talking to the remote server. When a request is sent to the remote server, a request signature will be generated using the key specified here and appended to the message. A request originating from the remote server is not required to be signed by this key. Although the grammar of the keys clause allows for multiple keys, only a single key per server is currently supported. The transfer-source and transfer-source-v6 clauses specify the IPv4 and IPv6 source address to be used for zone transfer with the remote server, respectively. For an IPv4 remote server, only transfer-source can be specified. Similarly, for an IPv6 remote server, only transfer-source-v6 can be specified. For more details, see the description of transfer-source and transfer-source-v6 in . The notify-source and notify-source-v6 clauses specify the IPv4 and IPv6 source address to be used for notify messages sent to remote servers, respectively. For an IPv4 remote server, only notify-source can be specified. Similarly, for an IPv6 remote server, only notify-source-v6 can be specified. The query-source and query-source-v6 clauses specify the IPv4 and IPv6 source address to be used for queries sent to remote servers, respectively. For an IPv4 remote server, only query-source can be specified. Similarly, for an IPv6 remote server, only query-source-v6 can be specified. <command>statistics-channels</command> Statement Grammar statistics-channels { [ inet ( ip_addr | * ) [ port ip_port ] [allow { address_match_list } ]; ] [ inet ...; ] }; <command>statistics-channels</command> Statement Definition and Usage The statistics-channels statement declares communication channels to be used by system administrators to get access to statistics information of the name server. This statement intends to be flexible to support multiple communication protocols in the future, but currently only HTTP access is supported. It requires that BIND 9 be compiled with libxml2; the statistics-channels statement is still accepted even if it is built without the library, but any HTTP access will fail with an error. An inet control channel is a TCP socket listening at the specified ip_port on the specified ip_addr, which can be an IPv4 or IPv6 address. An ip_addr of * (asterisk) is interpreted as the IPv4 wildcard address; connections will be accepted on any of the system's IPv4 addresses. To listen on the IPv6 wildcard address, use an ip_addr of ::. If no port is specified, port 80 is used for HTTP channels. The asterisk "*" cannot be used for ip_port. The attempt of opening a statistics channel is restricted by the optional allow clause. Connections to the statistics channel are permitted based on the address_match_list. If no allow clause is present, named accepts connection attempts from any address; since the statistics may contain sensitive internal information, it is highly recommended to restrict the source of connection requests appropriately. If no statistics-channels statement is present, named will not open any communication channels. <command>trusted-keys</command> Statement Grammar trusted-keys { string number number number string ; string number number number string ; ... }; <command>trusted-keys</command> Statement Definition and Usage The trusted-keys statement defines DNSSEC security roots. DNSSEC is described in . A security root is defined when the public key for a non-authoritative zone is known, but cannot be securely obtained through DNS, either because it is the DNS root zone or because its parent zone is unsigned. Once a key has been configured as a trusted key, it is treated as if it had been validated and proven secure. The resolver attempts DNSSEC validation on all DNS data in subdomains of a security root. All keys (and corresponding zones) listed in trusted-keys are deemed to exist regardless of what parent zones say. Similarly for all keys listed in trusted-keys only those keys are used to validate the DNSKEY RRset. The parent's DS RRset will not be used. The trusted-keys statement can contain multiple key entries, each consisting of the key's domain name, flags, protocol, algorithm, and the Base-64 representation of the key data. Spaces, tabs, newlines and carriage returns are ignored in the key data, so the configuration may be split up into multiple lines. <command>view</command> Statement Grammar view view_name class { match-clients { address_match_list }; match-destinations { address_match_list }; match-recursive-only yes_or_no ; view_option; ... zone_statement; ... }; <command>view</command> Statement Definition and Usage The view statement is a powerful feature of BIND 9 that lets a name server answer a DNS query differently depending on who is asking. It is particularly useful for implementing split DNS setups without having to run multiple servers. Each view statement defines a view of the DNS namespace that will be seen by a subset of clients. A client matches a view if its source IP address matches the address_match_list of the view's match-clients clause and its destination IP address matches the address_match_list of the view's match-destinations clause. If not specified, both match-clients and match-destinations default to matching all addresses. In addition to checking IP addresses match-clients and match-destinations can also take keys which provide an mechanism for the client to select the view. A view can also be specified as match-recursive-only, which means that only recursive requests from matching clients will match that view. The order of the view statements is significant — a client request will be resolved in the context of the first view that it matches. Zones defined within a view statement will only be accessible to clients that match the view. By defining a zone of the same name in multiple views, different zone data can be given to different clients, for example, "internal" and "external" clients in a split DNS setup. Many of the options given in the options statement can also be used within a view statement, and then apply only when resolving queries with that view. When no view-specific value is given, the value in the options statement is used as a default. Also, zone options can have default values specified in the view statement; these view-specific defaults take precedence over those in the options statement. Views are class specific. If no class is given, class IN is assumed. Note that all non-IN views must contain a hint zone, since only the IN class has compiled-in default hints. If there are no view statements in the config file, a default view that matches any client is automatically created in class IN. Any zone statements specified on the top level of the configuration file are considered to be part of this default view, and the options statement will apply to the default view. If any explicit view statements are present, all zone statements must occur inside view statements. Here is an example of a typical split DNS setup implemented using view statements: view "internal" { // This should match our internal networks. match-clients { 10.0.0.0/8; }; // Provide recursive service to internal clients only. recursion yes; // Provide a complete view of the example.com zone // including addresses of internal hosts. zone "example.com" { type master; file "example-internal.db"; }; }; view "external" { // Match all clients not matched by the previous view. match-clients { any; }; // Refuse recursive service to external clients. recursion no; // Provide a restricted view of the example.com zone // containing only publicly accessible hosts. zone "example.com" { type master; file "example-external.db"; }; }; <command>zone</command> Statement Grammar zone zone_name class { type master; allow-query { address_match_list }; allow-query-on { address_match_list }; allow-transfer { address_match_list }; allow-update { address_match_list };

}; <command>zone</command> Statement Definition and Usage Zone Types master The server has a master copy of the data for the zone and will be able to provide authoritative answers for it. slave A slave zone is a replica of a master zone. The masters list specifies one or more IP addresses of master servers that the slave contacts to update its copy of the zone. Masters list elements can also be names of other masters lists. By default, transfers are made from port 53 on the servers; this can be changed for all servers by specifying a port number before the list of IP addresses, or on a per-server basis after the IP address. Authentication to the master can also be done with per-server TSIG keys. If a file is specified, then the replica will be written to this file whenever the zone is changed, and reloaded from this file on a server restart. Use of a file is recommended, since it often speeds server startup and eliminates a needless waste of bandwidth. Note that for large numbers (in the tens or hundreds of thousands) of zones per server, it is best to use a two-level naming scheme for zone filenames. For example, a slave server for the zone example.com might place the zone contents into a file called ex/example.com where ex/ is just the first two letters of the zone name. (Most operating systems behave very slowly if you put 100000 files into a single directory.) stub A stub zone is similar to a slave zone, except that it replicates only the NS records of a master zone instead of the entire zone. Stub zones are not a standard part of the DNS; they are a feature specific to the BIND implementation. Stub zones can be used to eliminate the need for glue NS record in a parent zone at the expense of maintaining a stub zone entry and a set of name server addresses in named.conf. This usage is not recommended for new configurations, and BIND 9 supports it only in a limited way. In BIND 4/8, zone transfers of a parent zone included the NS records from stub children of that zone. This meant that, in some cases, users could get away with configuring child stubs only in the master server for the parent zone. BIND 9 never mixes together zone data from different zones in this way. Therefore, if a BIND 9 master serving a parent zone has child stub zones configured, all the slave servers for the parent zone also need to have the same child stub zones configured. Stub zones can also be used as a way of forcing the resolution of a given domain to use a particular set of authoritative servers. For example, the caching name servers on a private network using RFC1918 addressing may be configured with stub zones for 10.in-addr.arpa to use a set of internal name servers as the authoritative servers for that domain. forward A "forward zone" is a way to configure forwarding on a per-domain basis. A zone statement of type forward can contain a forward and/or forwarders statement, which will apply to queries within the domain given by the zone name. If no forwarders statement is present or an empty list for forwarders is given, then no forwarding will be done for the domain, canceling the effects of any forwarders in the options statement. Thus if you want to use this type of zone to change the behavior of the global forward option (that is, "forward first" to, then "forward only", or vice versa, but want to use the same servers as set globally) you need to re-specify the global forwarders. hint The initial set of root name servers is specified using a "hint zone". When the server starts up, it uses the root hints to find a root name server and get the most recent list of root name servers. If no hint zone is specified for class IN, the server uses a compiled-in default set of root servers hints. Classes other than IN have no built-in defaults hints. delegation-only This is used to enforce the delegation-only status of infrastructure zones (e.g. COM, NET, ORG). Any answer that is received without an explicit or implicit delegation in the authority section will be treated as NXDOMAIN. This does not apply to the zone apex. This should not be applied to leaf zones. delegation-only has no effect on answers received from forwarders. See caveats in . Class The zone's name may optionally be followed by a class. If a class is not specified, class IN (for Internet), is assumed. This is correct for the vast majority of cases. The hesiod class is named for an information service from MIT's Project Athena. It is used to share information about various systems databases, such as users, groups, printers and so on. The keyword HS is a synonym for hesiod. Another MIT development is Chaosnet, a LAN protocol created in the mid-1970s. Zone data for it can be specified with the CHAOS class.

See . allow-update-forwarding See the description of allow-update-forwarding in . also-notify Only meaningful if notify is active for this zone. The set of machines that will receive a DNS NOTIFY message for this zone is made up of all the listed name servers (other than the primary master) for the zone plus any IP addresses specified with also-notify. A port may be specified with each also-notify address to send the notify messages to a port other than the default of 53. also-notify is not meaningful for stub zones. The default is the empty list. check-names This option is used to restrict the character set and syntax of certain domain names in master files and/or DNS responses received from the network. The default varies according to zone type. For master zones the default is fail. For slave zones the default is warn. check-mx See the description of check-mx in . check-wildcard See the description of check-wildcard in . check-integrity See the description of check-integrity in . check-sibling See the description of check-sibling in . zero-no-soa-ttl See the description of zero-no-soa-ttl in . update-check-ksk See the description of update-check-ksk in . try-tcp-refresh See the description of try-tcp-refresh in . database Specify the type of database to be used for storing the zone data. The string following the database keyword is interpreted as a list of whitespace-delimited words. The first word identifies the database type, and any subsequent words are passed as arguments to the database to be interpreted in a way specific to the database type. The default is "rbt", BIND 9's native in-memory red-black-tree database. This database does not take arguments. Other values are possible if additional database drivers have been linked into the server. Some sample drivers are included with the distribution but none are linked in by default. dialup See the description of dialup in . delegation-only The flag only applies to hint and stub zones. If set to yes, then the zone will also be treated as if it is also a delegation-only type zone. See caveats in . forward Only meaningful if the zone has a forwarders list. The only value causes the lookup to fail after trying the forwarders and getting no answer, while first would allow a normal lookup to be tried. forwarders Used to override the list of global forwarders. If it is not specified in a zone of type forward, no forwarding is done for the zone and the global options are not used. ixfr-base Was used in BIND 8 to specify the name of the transaction log (journal) file for dynamic update and IXFR. BIND 9 ignores the option and constructs the name of the journal file by appending ".jnl" to the name of the zone file. ixfr-tmp-file Was an undocumented option in BIND 8. Ignored in BIND 9. journal Allow the default journal's filename to be overridden. The default is the zone's filename with ".jnl" appended.

Dynamic Update Policies BIND 9 supports two alternative methods of granting clients the right to perform dynamic updates to a zone, configured by the allow-update and update-policy option, respectively. The allow-update clause works the same way as in previous versions of BIND. It grants given clients the permission to update any record of any name in the zone. The update-policy clause is new in BIND 9 and allows more fine-grained control over what updates are allowed. A set of rules is specified, where each rule either grants or denies permissions for one or more names to be updated by one or more identities. If the dynamic update request message is signed (that is, it includes either a TSIG or SIG(0) record), the identity of the signer can be determined. Rules are specified in the update-policy zone option, and are only meaningful for master zones. When the update-policy statement is present, it is a configuration error for the allow-update statement to be present. The update-policy statement only examines the signer of a message; the source address is not relevant. This is how a rule definition looks: ( grant | deny ) identity nametype name types Each rule grants or denies privileges. Once a message has successfully matched a rule, the operation is immediately granted or denied and no further rules are examined. A rule is matched when the signer matches the identity field, the name matches the name field in accordance with the nametype field, and the type matches the types specified in the type field. No signer is required for tcp-self or 6to4-self however the standard reverse mapping / prefix conversion must match the identity field. The identity field specifies a name or a wildcard name. Normally, this is the name of the TSIG or SIG(0) key used to sign the update request. When a TKEY exchange has been used to create a shared secret, the identity of the shared secret is the same as the identity of the key used to authenticate the TKEY exchange. TKEY is also the negotiation method used by GSS-TSIG, which establishes an identity that is the Kerberos principal of the client, such as "user@host.domain". When the identity field specifies a wildcard name, it is subject to DNS wildcard expansion, so the rule will apply to multiple identities. The identity field must contain a fully-qualified domain name. For nametypes krb5-self, ms-self, krb5-subdomain, and ms-subdomain the identity field specifies the Windows or Kerberos realm of the machine belongs to. The nametype field has 12 values: name, subdomain, wildcard, self, selfsub, selfwild, krb5-self, ms-self, krb5-subdomain, ms-subdomain, tcp-self and 6to4-self. name Exact-match semantics. This rule matches when the name being updated is identical to the contents of the name field. subdomain This rule matches when the name being updated is a subdomain of, or identical to, the contents of the name field. wildcard The name field is subject to DNS wildcard expansion, and this rule matches when the name being updated name is a valid expansion of the wildcard. self This rule matches when the name being updated matches the contents of the identity field. The name field is ignored, but should be the same as the identity field. The self nametype is most useful when allowing using one key per name to update, where the key has the same name as the name to be updated. The identity would be specified as * (an asterisk) in this case. selfsub This rule is similar to self except that subdomains of self can also be updated. selfwild This rule is similar to self except that only subdomains of self can be updated. ms-self This rule takes a Windows machine principal (machine$@REALM) for machine in REALM and and converts it machine.realm allowing the machine to update machine.realm. The REALM to be matched is specified in the identity field. ms-subdomain This rule takes a Windows machine principal (machine$@REALM) for machine in REALM and converts it to machine.realm allowing the machine to update subdomains of machine.realm. The REALM to be matched is specified in the identity field. krb5-self This rule takes a Kerberos machine principal (host/machine@REALM) for machine in REALM and and converts it machine.realm allowing the machine to update machine.realm. The REALM to be matched is specified in the identity field. krb5-subdomain This rule takes a Kerberos machine principal (host/machine@REALM) for machine in REALM and converts it to machine.realm allowing the machine to update subdomains of machine.realm. The REALM to be matched is specified in the identity field. tcp-self Allow updates that have been sent via TCP and for which the standard mapping from the initiating IP address into the IN-ADDR.ARPA and IP6.ARPA namespaces match the name to be updated. It is theoretically possible to spoof these TCP sessions. 6to4-self Allow the 6to4 prefix to be update by any TCP conection from the 6to4 network or from the corresponding IPv4 address. This is intended to allow NS or DNAME RRsets to be added to the reverse tree. It is theoretically possible to spoof these TCP sessions. In all cases, the name field must specify a fully-qualified domain name. If no types are explicitly specified, this rule matches all types except RRSIG, NS, SOA, NSEC and NSEC3. Types may be specified by name, including "ANY" (ANY matches all types except NSEC and NSEC3, which can never be updated). Note that when an attempt is made to delete all records associated with a name, the rules are checked for each existing record type. Zone File Types of Resource Records and When to Use Them This section, largely borrowed from RFC 1034, describes the concept of a Resource Record (RR) and explains when each is used. Since the publication of RFC 1034, several new RRs have been identified and implemented in the DNS. These are also included. Resource Records A domain name identifies a node. Each node has a set of resource information, which may be empty. The set of resource information associated with a particular name is composed of separate RRs. The order of RRs in a set is not significant and need not be preserved by name servers, resolvers, or other parts of the DNS. However, sorting of multiple RRs is permitted for optimization purposes, for example, to specify that a particular nearby server be tried first. See and . The components of a Resource Record are: owner name The domain name where the RR is found. type An encoded 16-bit value that specifies the type of the resource record. TTL The time-to-live of the RR. This field is a 32-bit integer in units of seconds, and is primarily used by resolvers when they cache RRs. The TTL describes how long a RR can be cached before it should be discarded. class An encoded 16-bit value that identifies a protocol family or instance of a protocol. RDATA The resource data. The format of the data is type (and sometimes class) specific. The following are types of valid RRs: A A host address. In the IN class, this is a 32-bit IP address. Described in RFC 1035. AAAA IPv6 address. Described in RFC 1886. A6 IPv6 address. This can be a partial address (a suffix) and an indirection to the name where the rest of the address (the prefix) can be found. Experimental. Described in RFC 2874. AFSDB Location of AFS database servers. Experimental. Described in RFC 1183. APL Address prefix list. Experimental. Described in RFC 3123. CERT Holds a digital certificate. Described in RFC 2538. CNAME Identifies the canonical name of an alias. Described in RFC 1035. DHCID Is used for identifying which DHCP client is associated with this name. Described in RFC 4701. DNAME Replaces the domain name specified with another name to be looked up, effectively aliasing an entire subtree of the domain name space rather than a single record as in the case of the CNAME RR. Described in RFC 2672. DNSKEY Stores a public key associated with a signed DNS zone. Described in RFC 4034. DS Stores the hash of a public key associated with a signed DNS zone. Described in RFC 4034. GPOS Specifies the global position. Superseded by LOC. HINFO Identifies the CPU and OS used by a host. Described in RFC 1035. IPSECKEY Provides a method for storing IPsec keying material in DNS. Described in RFC 4025. ISDN Representation of ISDN addresses. Experimental. Described in RFC 1183. KEY Stores a public key associated with a DNS name. Used in original DNSSEC; replaced by DNSKEY in DNSSECbis, but still used with SIG(0). Described in RFCs 2535 and 2931. KX Identifies a key exchanger for this DNS name. Described in RFC 2230. LOC For storing GPS info. Described in RFC 1876. Experimental. MX Identifies a mail exchange for the domain with a 16-bit preference value (lower is better) followed by the host name of the mail exchange. Described in RFC 974, RFC 1035. NAPTR Name authority pointer. Described in RFC 2915. NSAP A network service access point. Described in RFC 1706. NS The authoritative name server for the domain. Described in RFC 1035. NSEC Used in DNSSECbis to securely indicate that RRs with an owner name in a certain name interval do not exist in a zone and indicate what RR types are present for an existing name. Described in RFC 4034. NSEC3 Used in DNSSECbis to securely indicate that RRs with an owner name in a certain name interval do not exist in a zone and indicate what RR types are present for an existing name. NSEC3 differs from NSEC in that it prevents zone enumeration but is more computationally expensive on both the server and the client than NSEC. Described in RFC 5155. NSEC3PARAM Used in DNSSECbis to tell the authoritative server which NSEC3 chains are available to use. Described in RFC 5155. NXT Used in DNSSEC to securely indicate that RRs with an owner name in a certain name interval do not exist in a zone and indicate what RR types are present for an existing name. Used in original DNSSEC; replaced by NSEC in DNSSECbis. Described in RFC 2535. PTR A pointer to another part of the domain name space. Described in RFC 1035. PX Provides mappings between RFC 822 and X.400 addresses. Described in RFC 2163. RP Information on persons responsible for the domain. Experimental. Described in RFC 1183. RRSIG Contains DNSSECbis signature data. Described in RFC 4034. RT Route-through binding for hosts that do not have their own direct wide area network addresses. Experimental. Described in RFC 1183. SIG Contains DNSSEC signature data. Used in original DNSSEC; replaced by RRSIG in DNSSECbis, but still used for SIG(0). Described in RFCs 2535 and 2931. SOA Identifies the start of a zone of authority. Described in RFC 1035. SPF Contains the Sender Policy Framework information for a given email domain. Described in RFC 4408. SRV Information about well known network services (replaces WKS). Described in RFC 2782. SSHFP Provides a way to securely publish a secure shell key's fingerprint. Described in RFC 4255. TXT Text records. Described in RFC 1035. WKS Information about which well known network services, such as SMTP, that a domain supports. Historical. X25 Representation of X.25 network addresses. Experimental. Described in RFC 1183. The following classes of resource records are currently valid in the DNS: IN The Internet. CH Chaosnet, a LAN protocol created at MIT in the mid-1970s. Rarely used for its historical purpose, but reused for BIND's built-in server information zones, e.g., version.bind. HS Hesiod, an information service developed by MIT's Project Athena. It is used to share information about various systems databases, such as users, groups, printers and so on. The owner name is often implicit, rather than forming an integral part of the RR. For example, many name servers internally form tree or hash structures for the name space, and chain RRs off nodes. The remaining RR parts are the fixed header (type, class, TTL) which is consistent for all RRs, and a variable part (RDATA) that fits the needs of the resource being described. The meaning of the TTL field is a time limit on how long an RR can be kept in a cache. This limit does not apply to authoritative data in zones; it is also timed out, but by the refreshing policies for the zone. The TTL is assigned by the administrator for the zone where the data originates. While short TTLs can be used to minimize caching, and a zero TTL prohibits caching, the realities of Internet performance suggest that these times should be on the order of days for the typical host. If a change can be anticipated, the TTL can be reduced prior to the change to minimize inconsistency during the change, and then increased back to its former value following the change. The data in the RDATA section of RRs is carried as a combination of binary strings and domain names. The domain names are frequently used as "pointers" to other data in the DNS. Textual expression of RRs RRs are represented in binary form in the packets of the DNS protocol, and are usually represented in highly encoded form when stored in a name server or resolver. In the examples provided in RFC 1034, a style similar to that used in master files was employed in order to show the contents of RRs. In this format, most RRs are shown on a single line, although continuation lines are possible using parentheses. The start of the line gives the owner of the RR. If a line begins with a blank, then the owner is assumed to be the same as that of the previous RR. Blank lines are often included for readability. Following the owner, we list the TTL, type, and class of the RR. Class and type use the mnemonics defined above, and TTL is an integer before the type field. In order to avoid ambiguity in parsing, type and class mnemonics are disjoint, TTLs are integers, and the type mnemonic is always last. The IN class and TTL values are often omitted from examples in the interests of clarity. The resource data or RDATA section of the RR are given using knowledge of the typical representation for the data. For example, we might show the RRs carried in a message as: ISI.EDU. MX 10 VENERA.ISI.EDU. MX 10 VAXA.ISI.EDU VENERA.ISI.EDU A 128.9.0.32 A 10.1.0.52 VAXA.ISI.EDU A 10.2.0.27 A 128.9.0.33 The MX RRs have an RDATA section which consists of a 16-bit number followed by a domain name. The address RRs use a standard IP address format to contain a 32-bit internet address. The above example shows six RRs, with two RRs at each of three domain names. Similarly we might see: XX.LCS.MIT.EDU. IN A 10.0.0.44 CH A MIT.EDU. 2420 This example shows two addresses for XX.LCS.MIT.EDU, each of a different class. Discussion of MX Records As described above, domain servers store information as a series of resource records, each of which contains a particular piece of information about a given domain name (which is usually, but not always, a host). The simplest way to think of a RR is as a typed pair of data, a domain name matched with a relevant datum, and stored with some additional type information to help systems determine when the RR is relevant. MX records are used to control delivery of email. The data specified in the record is a priority and a domain name. The priority controls the order in which email delivery is attempted, with the lowest number first. If two priorities are the same, a server is chosen randomly. If no servers at a given priority are responding, the mail transport agent will fall back to the next largest priority. Priority numbers do not have any absolute meaning — they are relevant only respective to other MX records for that domain name. The domain name given is the machine to which the mail will be delivered. It must have an associated address record (A or AAAA) — CNAME is not sufficient. For a given domain, if there is both a CNAME record and an MX record, the MX record is in error, and will be ignored. Instead, the mail will be delivered to the server specified in the MX record pointed to by the CNAME. For example: example.com. IN MX 10 mail.example.com. IN MX 10 mail2.example.com. IN MX 20 mail.backup.org. mail.example.com. IN A 10.0.0.1 mail2.example.com. IN A 10.0.0.2 Mail delivery will be attempted to mail.example.com and mail2.example.com (in any order), and if neither of those succeed, delivery to mail.backup.org will be attempted. Setting TTLs The time-to-live of the RR field is a 32-bit integer represented in units of seconds, and is primarily used by resolvers when they cache RRs. The TTL describes how long a RR can be cached before it should be discarded. The following three types of TTL are currently used in a zone file. SOA The last field in the SOA is the negative caching TTL. This controls how long other servers will cache no-such-domain (NXDOMAIN) responses from you. The maximum time for negative caching is 3 hours (3h). $TTL The $TTL directive at the top of the zone file (before the SOA) gives a default TTL for every RR without a specific TTL set. RR TTLs Each RR can have a TTL as the second field in the RR, which will control how long other servers can cache the it. All of these TTLs default to units of seconds, though units can be explicitly specified, for example, 1h30m. Inverse Mapping in IPv4 Reverse name resolution (that is, translation from IP address to name) is achieved by means of the in-addr.arpa domain and PTR records. Entries in the in-addr.arpa domain are made in least-to-most significant order, read left to right. This is the opposite order to the way IP addresses are usually written. Thus, a machine with an IP address of 10.1.2.3 would have a corresponding in-addr.arpa name of 3.2.1.10.in-addr.arpa. This name should have a PTR resource record whose data field is the name of the machine or, optionally, multiple PTR records if the machine has more than one name. For example, in the example.com domain: $ORIGIN 2.1.10.in-addr.arpa 3 IN PTR foo.example.com. The $ORIGIN lines in the examples are for providing context to the examples only — they do not necessarily appear in the actual usage. They are only used here to indicate that the example is relative to the listed origin. Other Zone File Directives The Master File Format was initially defined in RFC 1035 and has subsequently been extended. While the Master File Format itself is class independent all records in a Master File must be of the same class. Master File Directives include $ORIGIN, $INCLUDE, and $TTL. The <command>@</command> (at-sign) When used in the label (or name) field, the asperand or at-sign (@) symbol represents the current origin. At the start of the zone file, it is the <zone_name> (followed by trailing dot). The <command>$ORIGIN</command> Directive Syntax: $ORIGIN domain-name comment $ORIGIN sets the domain name that will be appended to any unqualified records. When a zone is first read in there is an implicit $ORIGIN <zone_name>. (followed by trailing dot). The current $ORIGIN is appended to the domain specified in the $ORIGIN argument if it is not absolute. $ORIGIN example.com. WWW CNAME MAIN-SERVER is equivalent to WWW.EXAMPLE.COM. CNAME MAIN-SERVER.EXAMPLE.COM. The <command>$INCLUDE</command> Directive Syntax: $INCLUDE filename origin comment Read and process the file filename as if it were included into the file at this point. If origin is specified the file is processed with $ORIGIN set to that value, otherwise the current $ORIGIN is used. The origin and the current domain name revert to the values they had prior to the $INCLUDE once the file has been read. RFC 1035 specifies that the current origin should be restored after an $INCLUDE, but it is silent on whether the current domain name should also be restored. BIND 9 restores both of them. This could be construed as a deviation from RFC 1035, a feature, or both. The <command>$TTL</command> Directive Syntax: $TTL default-ttl comment Set the default Time To Live (TTL) for subsequent records with undefined TTLs. Valid TTLs are of the range 0-2147483647 seconds. $TTL is defined in RFC 2308. <acronym>BIND</acronym> Master File Extension: the <command>$GENERATE</command> Directive Syntax: $GENERATE range lhs ttl class type rhs comment $GENERATE is used to create a series of resource records that only differ from each other by an iterator. $GENERATE can be used to easily generate the sets of records required to support sub /24 reverse delegations described in RFC 2317: Classless IN-ADDR.ARPA delegation. $ORIGIN 0.0.192.IN-ADDR.ARPA. $GENERATE 1-2 0 NS SERVER$.EXAMPLE. $GENERATE 1-127 $ CNAME $.0 is equivalent to 0.0.0.192.IN-ADDR.ARPA. NS SERVER1.EXAMPLE. 0.0.0.192.IN-ADDR.ARPA. NS SERVER2.EXAMPLE. 1.0.0.192.IN-ADDR.ARPA. CNAME 1.0.0.0.192.IN-ADDR.ARPA. 2.0.0.192.IN-ADDR.ARPA. CNAME 2.0.0.0.192.IN-ADDR.ARPA. ... 127.0.0.192.IN-ADDR.ARPA. CNAME 127.0.0.0.192.IN-ADDR.ARPA. range This can be one of two forms: start-stop or start-stop/step. If the first form is used, then step is set to 1. All of start, stop and step must be positive. lhs This describes the owner name of the resource records to be created. Any single $ (dollar sign) symbols within the lhs string are replaced by the iterator value. To get a $ in the output, you need to escape the $ using a backslash \, e.g. \$. The $ may optionally be followed by modifiers which change the offset from the iterator, field width and base. Modifiers are introduced by a { (left brace) immediately following the $ as ${offset[,width[,base]]}. For example, ${-20,3,d} subtracts 20 from the current value, prints the result as a decimal in a zero-padded field of width 3. Available output forms are decimal (d), octal (o) and hexadecimal (x or X for uppercase). The default modifier is ${0,0,d}. If the lhs is not absolute, the current $ORIGIN is appended to the name. For compatibility with earlier versions, $$ is still recognized as indicating a literal $ in the output. ttl Specifies the time-to-live of the generated records. If not specified this will be inherited using the normal TTL inheritance rules. class and ttl can be entered in either order. class Specifies the class of the generated records. This must match the zone class if it is specified. class and ttl can be entered in either order. type At present the only supported types are PTR, CNAME, DNAME, A, AAAA and NS. rhs rhs is a domain name. It is processed similarly to lhs. The $GENERATE directive is a BIND extension and not part of the standard zone file format. BIND 8 does not support the optional TTL and CLASS fields. Additional File Formats In addition to the standard textual format, BIND 9 supports the ability to read or dump to zone files in other formats. The raw format is currently available as an additional format. It is a binary format representing BIND 9's internal data structure directly, thereby remarkably improving the loading time. For a primary server, a zone file in the raw format is expected to be generated from a textual zone file by the named-compilezone command. For a secondary server or for a dynamic zone, it is automatically generated (if this format is specified by the masterfile-format option) when named dumps the zone contents after zone transfer or when applying prior updates. If a zone file in a binary format needs manual modification, it first must be converted to a textual form by the named-compilezone command. All necessary modification should go to the text file, which should then be converted to the binary form by the named-compilezone command again. Although the raw format uses the network byte order and avoids architecture-dependent data alignment so that it is as much portable as possible, it is primarily expected to be used inside the same single system. In order to export a zone file in the raw format or make a portable backup of the file, it is recommended to convert the file to the standard textual representation. BIND9 Statistics BIND 9 maintains lots of statistics information and provides several interfaces for users to get access to the statistics. The available statistics include all statistics counters that were available in BIND 8 and are meaningful in BIND 9, and other information that is considered useful. The statistics information is categorized into the following sections. Incoming Requests The number of incoming DNS requests for each OPCODE. Incoming Queries The number of incoming queries for each RR type. Outgoing Queries The number of outgoing queries for each RR type sent from the internal resolver. Maintained per view. Name Server Statistics Statistics counters about incoming request processing. Zone Maintenance Statistics Statistics counters regarding zone maintenance operations such as zone transfers. Resolver Statistics Statistics counters about name resolution performed in the internal resolver. Maintained per view. Cache DB RRsets The number of RRsets per RR type (positive or negative) and nonexistent names stored in the cache database. Maintained per view. Socket I/O Statistics Statistics counters about network related events. A subset of Name Server Statistics is collected and shown per zone for which the server has the authority when zone-statistics is set to yes. These statistics counters are shown with their zone and view names. In some cases the view names are omitted for the default view. There are currently two user interfaces to get access to the statistics. One is in the plain text format dumped to the file specified by the statistics-file configuration option. The other is remotely accessible via a statistics channel when the statistics-channels statement is specified in the configuration file (see .) The Statistics File The text format statistics dump begins with a line, like: +++ Statistics Dump +++ (973798949) The number in parentheses is a standard Unix-style timestamp, measured as seconds since January 1, 1970. Following that line is a set of statistics information, which is categorized as described above. Each section begins with a line, like: ++ Name Server Statistics ++ Each section consists of lines, each containing the statistics counter value followed by its textual description. See below for available counters. For brevity, counters that have a value of 0 are not shown in the statistics file. The statistics dump ends with the line where the number is identical to the number in the beginning line; for example: --- Statistics Dump --- (973798949) Statistics Counters The following tables summarize statistics counters that BIND 9 provides. For each row of the tables, the leftmost column is the abbreviated symbol name of that counter. These symbols are shown in the statistics information accessed via an HTTP statistics channel. The rightmost column gives the description of the counter, which is also shown in the statistics file (but, in this document, possibly with slight modification for better readability). Additional notes may also be provided in this column. When a middle column exists between these two columns, it gives the corresponding counter name of the BIND 8 statistics, if applicable. Name Server Statistics Counters Symbol BIND8 Symbol Description Requestv4 RQ IPv4 requests received. Note: this also counts non query requests. Requestv6 RQ IPv6 requests received. Note: this also counts non query requests. ReqEdns0 Requests with EDNS(0) received. ReqBadEDNSVer Requests with unsupported EDNS version received. ReqTSIG Requests with TSIG received.

RespTruncated Truncated responses sent. RespEDNS0 Responses with EDNS(0) sent. RespTSIG Responses with TSIG sent. RespSIG0 Responses with SIG(0) sent. QrySuccess Queries resulted in a successful answer. This means the query which returns a NOERROR response with at least one answer RR. This corresponds to the success counter of previous versions of BIND 9. QryAuthAns Queries resulted in authoritative answer. QryNoauthAns SNaAns Queries resulted in non authoritative answer. QryReferral Queries resulted in referral answer. This corresponds to the referral counter of previous versions of BIND 9. QryNxrrset Queries resulted in NOERROR responses with no data. This corresponds to the nxrrset counter of previous versions of BIND 9. QrySERVFAIL SFail Queries resulted in SERVFAIL. QryFORMERR SFErr Queries resulted in FORMERR. QryNXDOMAIN SNXD Queries resulted in NXDOMAIN. This corresponds to the nxdomain counter of previous versions of BIND 9. QryRecursion RFwdQ Queries which caused the server to perform recursion in order to find the final answer. This corresponds to the recursion counter of previous versions of BIND 9. QryDuplicate RDupQ Queries which the server attempted to recurse but discovered an existing query with the same IP address, port, query ID, name, type and class already being processed. This corresponds to the duplicate counter of previous versions of BIND 9. QryDropped Recursive queries for which the server discovered an excessive number of existing recursive queries for the same name, type and class and were subsequently dropped. This is the number of dropped queries due to the reason explained with the clients-per-query and max-clients-per-query options (see the description about .) This corresponds to the dropped counter of previous versions of BIND 9. QryFailure Other query failures. This corresponds to the failure counter of previous versions of BIND 9. Note: this counter is provided mainly for backward compatibility with the previous versions. Normally a more fine-grained counters such as AuthQryRej and RecQryRej that would also fall into this counter are provided, and so this counter would not be of much interest in practice. XfrReqDone Requested zone transfers completed. UpdateReqFwd Update requests forwarded. UpdateRespFwd Update responses forwarded. UpdateFwdFail Dynamic update forward failed.

ValOk DNSSEC validation succeeded. ValNegOk DNSSEC validation on negative information succeeded. ValFail DNSSEC validation failed. QryRTTnn Frequency table on round trip times (RTTs) of queries. Each nn specifies the corresponding frequency. In the sequence of nn_1, nn_2, ..., nn_m, the value of nn_i is the number of queries whose RTTs are between nn_(i-1) (inclusive) and nn_i (exclusive) milliseconds. For the sake of convenience we define nn_0 to be 0. The last entry should be represented as nn_m+, which means the number of queries whose RTTs are equal to or over nn_m milliseconds. Socket I/O Statistics Counters Socket I/O statistics counters are defined per socket types, which are UDP4 (UDP/IPv4), UDP6 (UDP/IPv6), TCP4 (TCP/IPv4), TCP6 (TCP/IPv6), Unix (Unix Domain), and FDwatch (sockets opened outside the socket module). In the following table <TYPE> represents a socket type. Not all counters are available for all socket types; exceptions are noted in the description field. Symbol Description <TYPE>Open Sockets opened successfully. This counter is not applicable to the FDwatch type. <TYPE>OpenFail Failures of opening sockets. This counter is not applicable to the FDwatch type. <TYPE>Close Sockets closed. <TYPE>BindFail Failures of binding sockets. <TYPE>ConnFail Failures of connecting sockets. <TYPE>Conn Connections established successfully. <TYPE>AcceptFail Failures of accepting incoming connection requests. This counter is not applicable to the UDP and FDwatch types. <TYPE>Accept Incoming connections successfully accepted. This counter is not applicable to the UDP and FDwatch types. <TYPE>SendErr Errors in socket send operations. This counter corresponds to SErr counter of BIND 8. <TYPE>RecvErr Errors in socket receive operations. This includes errors of send operations on a connected UDP socket notified by an ICMP error message. Compatibility with <emphasis>BIND</emphasis> 8 Counters Most statistics counters that were available in BIND 8 are also supported in BIND 9 as shown in the above tables. Here are notes about other counters that do not appear in these tables. RFwdR,SFwdR These counters are not supported because BIND 9 does not adopt the notion of forwarding as BIND 8 did. RAXFR This counter is accessible in the Incoming Queries section. RIQ This counter is accessible in the Incoming Requests section. ROpts This counter is not supported because BIND 9 does not care about IP options in the first place. <acronym>BIND</acronym> 9 Security Considerations Access Control Lists Access Control Lists (ACLs) are address match lists that you can set up and nickname for future use in allow-notify, allow-query, allow-query-on, allow-recursion, allow-recursion-on, blackhole, allow-transfer, etc. Using ACLs allows you to have finer control over who can access your name server, without cluttering up your config files with huge lists of IP addresses. It is a good idea to use ACLs, and to control access to your server. Limiting access to your server by outside parties can help prevent spoofing and denial of service (DoS) attacks against your server. Here is an example of how to properly apply ACLs: // Set up an ACL named "bogusnets" that will block RFC1918 space // and some reserved space, which is commonly used in spoofing attacks. acl bogusnets { 0.0.0.0/8; 192.0.2.0/24; 224.0.0.0/3; 10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16; }; // Set up an ACL called our-nets. Replace this with the real IP numbers. acl our-nets { x.x.x.x/24; x.x.x.x/21; }; options { ... ... allow-query { our-nets; }; allow-recursion { our-nets; }; ... blackhole { bogusnets; }; ... }; zone "example.com" { type master; file "m/example.com"; allow-query { any; }; }; This allows recursive queries of the server from the outside unless recursion has been previously disabled. For more information on how to use ACLs to protect your server, see the AUSCERT advisory at: ftp://ftp.auscert.org.au/pub/auscert/advisory/AL-1999.004.dns_dos <command>Chroot</command> and <command>Setuid</command> On UNIX servers, it is possible to run BIND in a chrooted environment (using the chroot() function) by specifying the "" option for named. This can help improve system security by placing BIND in a "sandbox", which will limit the damage done if a server is compromised. Another useful feature in the UNIX version of BIND is the ability to run the daemon as an unprivileged user ( user ). We suggest running as an unprivileged user when using the chroot feature. Here is an example command line to load BIND in a chroot sandbox, /var/named, and to run named setuid to user 202: /usr/local/sbin/named -u 202 -t /var/named The <command>chroot</command> Environment In order for a chroot environment to work properly in a particular directory (for example, /var/named), you will need to set up an environment that includes everything BIND needs to run. From BIND's point of view, /var/named is the root of the filesystem. You will need to adjust the values of options like like directory and pid-file to account for this. Unlike with earlier versions of BIND, you typically will not need to compile named statically nor install shared libraries under the new root. However, depending on your operating system, you may need to set up things like /dev/zero, /dev/random, /dev/log, and /etc/localtime. Using the <command>setuid</command> Function Prior to running the named daemon, use the touch utility (to change file access and modification times) or the chown utility (to set the user id and/or group id) on files to which you want BIND to write. Note that if the named daemon is running as an unprivileged user, it will not be able to bind to new restricted ports if the server is reloaded. Dynamic Update Security Access to the dynamic update facility should be strictly limited. In earlier versions of BIND, the only way to do this was based on the IP address of the host requesting the update, by listing an IP address or network prefix in the allow-update zone option. This method is insecure since the source address of the update UDP packet is easily forged. Also note that if the IP addresses allowed by the allow-update option include the address of a slave server which performs forwarding of dynamic updates, the master can be trivially attacked by sending the update to the slave, which will forward it to the master with its own source IP address causing the master to approve it without question. For these reasons, we strongly recommend that updates be cryptographically authenticated by means of transaction signatures (TSIG). That is, the allow-update option should list only TSIG key names, not IP addresses or network prefixes. Alternatively, the new update-policy option can be used. Some sites choose to keep all dynamically-updated DNS data in a subdomain and delegate that subdomain to a separate zone. This way, the top-level zone containing critical data such as the IP addresses of public web and mail servers need not allow dynamic update at all. Troubleshooting Common Problems It's not working; how can I figure out what's wrong? The best solution to solving installation and configuration issues is to take preventative measures by setting up logging files beforehand. The log files provide a source of hints and information that can be used to figure out what went wrong and how to fix the problem. Incrementing and Changing the Serial Number Zone serial numbers are just numbers — they aren't date related. A lot of people set them to a number that represents a date, usually of the form YYYYMMDDRR. Occasionally they will make a mistake and set them to a "date in the future" then try to correct them by setting them to the "current date". This causes problems because serial numbers are used to indicate that a zone has been updated. If the serial number on the slave server is lower than the serial number on the master, the slave server will attempt to update its copy of the zone. Setting the serial number to a lower number on the master server than the slave server means that the slave will not perform updates to its copy of the zone. The solution to this is to add 2147483647 (2^31-1) to the number, reload the zone and make sure all slaves have updated to the new zone serial number, then reset the number to what you want it to be, and reload the zone again. Where Can I Get Help? The Internet Systems Consortium (ISC) offers a wide range of support and service agreements for BIND and DHCP servers. Four levels of premium support are available and each level includes support for all ISC programs, significant discounts on products and training, and a recognized priority on bug fixes and non-funded feature requests. In addition, ISC offers a standard support agreement package which includes services ranging from bug fix announcements to remote support. It also includes training in BIND and DHCP. To discuss arrangements for support, contact info@isc.org or visit the ISC web page at http://www.isc.org/services/support/ to read more. Appendices Acknowledgments A Brief History of the <acronym>DNS</acronym> and <acronym>BIND</acronym> Although the "official" beginning of the Domain Name System occurred in 1984 with the publication of RFC 920, the core of the new system was described in 1983 in RFCs 882 and 883. From 1984 to 1987, the ARPAnet (the precursor to today's Internet) became a testbed of experimentation for developing the new naming/addressing scheme in a rapidly expanding, operational network environment. New RFCs were written and published in 1987 that modified the original documents to incorporate improvements based on the working model. RFC 1034, "Domain Names-Concepts and Facilities", and RFC 1035, "Domain Names-Implementation and Specification" were published and became the standards upon which all DNS implementations are built. The first working domain name server, called "Jeeves", was written in 1983-84 by Paul Mockapetris for operation on DEC Tops-20 machines located at the University of Southern California's Information Sciences Institute (USC-ISI) and SRI International's Network Information Center (SRI-NIC). A DNS server for Unix machines, the Berkeley Internet Name Domain (BIND) package, was written soon after by a group of graduate students at the University of California at Berkeley under a grant from the US Defense Advanced Research Projects Administration (DARPA). Versions of BIND through 4.8.3 were maintained by the Computer Systems Research Group (CSRG) at UC Berkeley. Douglas Terry, Mark Painter, David Riggle and Songnian Zhou made up the initial BIND project team. After that, additional work on the software package was done by Ralph Campbell. Kevin Dunlap, a Digital Equipment Corporation employee on loan to the CSRG, worked on BIND for 2 years, from 1985 to 1987. Many other people also contributed to BIND development during that time: Doug Kingston, Craig Partridge, Smoot Carl-Mitchell, Mike Muuss, Jim Bloom and Mike Schwartz. BIND maintenance was subsequently handled by Mike Karels and Øivind Kure. BIND versions 4.9 and 4.9.1 were released by Digital Equipment Corporation (now Compaq Computer Corporation). Paul Vixie, then a DEC employee, became BIND's primary caretaker. He was assisted by Phil Almquist, Robert Elz, Alan Barrett, Paul Albitz, Bryan Beecher, Andrew Partan, Andy Cherenson, Tom Limoncelli, Berthold Paffrath, Fuat Baran, Anant Kumar, Art Harkin, Win Treese, Don Lewis, Christophe Wolfhugel, and others. In 1994, BIND version 4.9.2 was sponsored by Vixie Enterprises. Paul Vixie became BIND's principal architect/programmer. BIND versions from 4.9.3 onward have been developed and maintained by the Internet Systems Consortium and its predecessor, the Internet Software Consortium, with support being provided by ISC's sponsors. As co-architects/programmers, Bob Halley and Paul Vixie released the first production-ready version of BIND version 8 in May 1997. BIND version 9 was released in September 2000 and is a major rewrite of nearly all aspects of the underlying BIND architecture. BIND versions 4 and 8 are officially deprecated. No additional development is done on BIND version 4 or BIND version 8. BIND development work is made possible today by the sponsorship of several corporations, and by the tireless work efforts of numerous individuals. General <acronym>DNS</acronym> Reference Information IPv6 addresses (AAAA) IPv6 addresses are 128-bit identifiers for interfaces and sets of interfaces which were introduced in the DNS to facilitate scalable Internet routing. There are three types of addresses: Unicast, an identifier for a single interface; Anycast, an identifier for a set of interfaces; and Multicast, an identifier for a set of interfaces. Here we describe the global Unicast address scheme. For more information, see RFC 3587, "Global Unicast Address Format." IPv6 unicast addresses consist of a global routing prefix, a subnet identifier, and an interface identifier. The global routing prefix is provided by the upstream provider or ISP, and (roughly) corresponds to the IPv4 network section of the address range. The subnet identifier is for local subnetting, much the same as subnetting an IPv4 /16 network into /24 subnets. The interface identifier is the address of an individual interface on a given network; in IPv6, addresses belong to interfaces rather than to machines. The subnetting capability of IPv6 is much more flexible than that of IPv4: subnetting can be carried out on bit boundaries, in much the same way as Classless InterDomain Routing (CIDR), and the DNS PTR representation ("nibble" format) makes setting up reverse zones easier. The Interface Identifier must be unique on the local link, and is usually generated automatically by the IPv6 implementation, although it is usually possible to override the default setting if necessary. A typical IPv6 address might look like: 2001:db8:201:9:a00:20ff:fe81:2b32 IPv6 address specifications often contain long strings of zeros, so the architects have included a shorthand for specifying them. The double colon (`::') indicates the longest possible string of zeros that can fit, and can be used only once in an address.

    The Internet Domain Name System (DNS) consists of the syntax to specify the names of entities in the Internet in a hierarchical manner, the rules used for delegating authority over names, and the system implementation that actually maps names to Internet addresses. DNS data is maintained in a group of distributed hierarchical databases.

    Scope of Document

    The Berkeley Internet Name Domain (BIND) implements a domain name server for a number of operating systems. This document provides basic information about the installation and care of the Internet Systems Consortium (ISC) BIND version 9 software package for system administrators.

    This version of the manual corresponds to BIND version 9.6.

    Organization of This Document

    In this document, Chapter 1 introduces the basic DNS and BIND concepts. Chapter 2 describes resource requirements for running BIND in various environments. Information in Chapter 3 is task-oriented in its presentation and is organized functionally, to aid in the process of installing the BIND 9 software. The task-oriented section is followed by Chapter 4, which contains more advanced concepts that the system administrator may need for implementing certain options. Chapter 5 describes the BIND 9 lightweight resolver. The contents of Chapter 6 are organized as in a reference manual to aid in the ongoing maintenance of the software. Chapter 7 addresses security considerations, and Chapter 8 contains troubleshooting help. The main body of the document is followed by several appendices which contain useful reference information, such as a bibliography and historic information related to BIND and the Domain Name System.

    The Domain Name System (DNS)

    The purpose of this document is to explain the installation and upkeep of the BIND (Berkeley Internet Name Domain) software package, and we begin by reviewing the fundamentals of the Domain Name System (DNS) as they relate to BIND.

    DNS Fundamentals

    The Domain Name System (DNS) is a hierarchical, distributed database. It stores information for mapping Internet host names to IP addresses and vice versa, mail routing information, and other data used by Internet applications.

    Clients look up information in the DNS by calling a resolver library, which sends queries to one or more name servers and interprets the responses. The BIND 9 software distribution contains a name server, named, and a resolver library, liblwres. The older libbind resolver library is also available from ISC as a separate download.

    Domains and Domain Names

    The data stored in the DNS is identified by domain names that are organized as a tree according to organizational or administrative boundaries. Each node of the tree, called a domain, is given a label. The domain name of the node is the concatenation of all the labels on the path from the node to the root node. This is represented in written form as a string of labels listed from right to left and separated by dots. A label need only be unique within its parent domain.

    For example, a domain name for a host at the company Example, Inc. could be ourhost.example.com, where com is the top level domain to which ourhost.example.com belongs, example is a subdomain of com, and ourhost is the name of the host.

    For administrative purposes, the name space is partitioned into areas called zones, each starting at a node and extending down to the leaf nodes or to nodes where other zones start. The data for each zone is stored in a name server, which answers queries about the zone using the DNS protocol.

    The data associated with each domain name is stored in the form of resource records (RRs). Some of the supported resource record types are described in the section called “Types of Resource Records and When to Use Them”.

    For more detailed information about the design of the DNS and the DNS protocol, please refer to the standards documents listed in the section called “Request for Comments (RFCs)”.

    Zones

    To properly operate a name server, it is important to understand the difference between a zone and a domain.

    As stated previously, a zone is a point of delegation in the DNS tree. A zone consists of those contiguous parts of the domain tree for which a name server has complete information and over which it has authority. It contains all domain names from a certain point downward in the domain tree except those which are delegated to other zones. A delegation point is marked by one or more NS records in the parent zone, which should be matched by equivalent NS records at the root of the delegated zone.

    For instance, consider the example.com domain which includes names such as host.aaa.example.com and host.bbb.example.com even though the example.com zone includes only delegations for the aaa.example.com and bbb.example.com zones. A zone can map exactly to a single domain, but could also include only part of a domain, the rest of which could be delegated to other name servers. Every name in the DNS tree is a domain, even if it is terminal, that is, has no subdomains. Every subdomain is a domain and every domain except the root is also a subdomain. The terminology is not intuitive and we suggest that you read RFCs 1033, 1034 and 1035 to gain a complete understanding of this difficult and subtle topic.

    Though BIND is called a "domain name server", it deals primarily in terms of zones. The master and slave declarations in the named.conf file specify zones, not domains. When you ask some other site if it is willing to be a slave server for your domain, you are actually asking for slave service for some collection of zones.

    Authoritative Name Servers

    Each zone is served by at least one authoritative name server, which contains the complete data for the zone. To make the DNS tolerant of server and network failures, most zones have two or more authoritative servers, on different networks.

    Responses from authoritative servers have the "authoritative answer" (AA) bit set in the response packets. This makes them easy to identify when debugging DNS configurations using tools like dig (the section called “Diagnostic Tools”).

    The Primary Master

    The authoritative server where the master copy of the zone data is maintained is called the primary master server, or simply the primary. Typically it loads the zone contents from some local file edited by humans or perhaps generated mechanically from some other local file which is edited by humans. This file is called the zone file or master file.

    In some cases, however, the master file may not be edited by humans at all, but may instead be the result of dynamic update operations.

    Slave Servers

    The other authoritative servers, the slave servers (also known as secondary servers) load the zone contents from another server using a replication process known as a zone transfer. Typically the data are transferred directly from the primary master, but it is also possible to transfer it from another slave. In other words, a slave server may itself act as a master to a subordinate slave server.

    Stealth Servers

    Usually all of the zone's authoritative servers are listed in NS records in the parent zone. These NS records constitute a delegation of the zone from the parent. The authoritative servers are also listed in the zone file itself, at the top level or apex of the zone. You can list servers in the zone's top-level NS records that are not in the parent's NS delegation, but you cannot list servers in the parent's delegation that are not present at the zone's top level.

    A stealth server is a server that is authoritative for a zone but is not listed in that zone's NS records. Stealth servers can be used for keeping a local copy of a zone to speed up access to the zone's records or to make sure that the zone is available even if all the "official" servers for the zone are inaccessible.

    A configuration where the primary master server itself is a stealth server is often referred to as a "hidden primary" configuration. One use for this configuration is when the primary master is behind a firewall and therefore unable to communicate directly with the outside world.

    Caching Name Servers

    The resolver libraries provided by most operating systems are stub resolvers, meaning that they are not capable of performing the full DNS resolution process by themselves by talking directly to the authoritative servers. Instead, they rely on a local name server to perform the resolution on their behalf. Such a server is called a recursive name server; it performs recursive lookups for local clients.

    To improve performance, recursive servers cache the results of the lookups they perform. Since the processes of recursion and caching are intimately connected, the terms recursive server and caching server are often used synonymously.

    The length of time for which a record may be retained in the cache of a caching name server is controlled by the Time To Live (TTL) field associated with each resource record.

    Forwarding

    Even a caching name server does not necessarily perform the complete recursive lookup itself. Instead, it can forward some or all of the queries that it cannot satisfy from its cache to another caching name server, commonly referred to as a forwarder.

    There may be one or more forwarders, and they are queried in turn until the list is exhausted or an answer is found. Forwarders are typically used when you do not wish all the servers at a given site to interact directly with the rest of the Internet servers. A typical scenario would involve a number of internal DNS servers and an Internet firewall. Servers unable to pass packets through the firewall would forward to the server that can do it, and that server would query the Internet DNS servers on the internal server's behalf.

    Name Servers in Multiple Roles

    The BIND name server can simultaneously act as a master for some zones, a slave for other zones, and as a caching (recursive) server for a set of local clients.

    However, since the functions of authoritative name service and caching/recursive name service are logically separate, it is often advantageous to run them on separate server machines. A server that only provides authoritative name service (an authoritative-only server) can run with recursion disabled, improving reliability and security. A server that is not authoritative for any zones and only provides recursive service to local clients (a caching-only server) does not need to be reachable from the Internet at large and can be placed inside a firewall.

    Hardware requirements

    DNS hardware requirements have traditionally been quite modest. For many installations, servers that have been pensioned off from active duty have performed admirably as DNS servers.

    The DNSSEC features of BIND 9 may prove to be quite CPU intensive however, so organizations that make heavy use of these features may wish to consider larger systems for these applications. BIND 9 is fully multithreaded, allowing full utilization of multiprocessor systems for installations that need it.

    CPU Requirements

    CPU requirements for BIND 9 range from i486-class machines for serving of static zones without caching, to enterprise-class machines if you intend to process many dynamic updates and DNSSEC signed zones, serving many thousands of queries per second.

    Memory Requirements

    The memory of the server has to be large enough to fit the cache and zones loaded off disk. The max-cache-size option can be used to limit the amount of memory used by the cache, at the expense of reducing cache hit rates and causing more DNS traffic. Additionally, if additional section caching (the section called “Additional Section Caching”) is enabled, the max-acache-size option can be used to limit the amount of memory used by the mechanism. It is still good practice to have enough memory to load all zone and cache data into memory — unfortunately, the best way to determine this for a given installation is to watch the name server in operation. After a few weeks the server process should reach a relatively stable size where entries are expiring from the cache as fast as they are being inserted.

    Name Server Intensive Environment Issues

    For name server intensive environments, there are two alternative configurations that may be used. The first is where clients and any second-level internal name servers query a main name server, which has enough memory to build a large cache. This approach minimizes the bandwidth used by external name lookups. The second alternative is to set up second-level internal name servers to make queries independently. In this configuration, none of the individual machines needs to have as much memory or CPU power as in the first alternative, but this has the disadvantage of making many more external queries, as none of the name servers share their cached data.

    Supported Operating Systems

    ISC BIND 9 compiles and runs on a large number of Unix-like operating systems and on NT-derived versions of Microsoft Windows such as Windows 2000 and Windows XP. For an up-to-date list of supported systems, see the README file in the top level directory of the BIND 9 source distribution.

    In this chapter we provide some suggested configurations along with guidelines for their use. We suggest reasonable values for certain option settings.

    Sample Configurations

    A Caching-only Name Server

    The following sample configuration is appropriate for a caching-only name server for use by clients internal to a corporation. All queries from outside clients are refused using the allow-query option. Alternatively, the same effect could be achieved using suitable firewall rules. 

    // Two corporate subnets we wish to allow queries from.
acl corpnets { 192.168.4.0/24; 192.168.7.0/24; };
options {
     directory "/etc/namedb";           // Working directory
     allow-query { corpnets; };
};
// Provide a reverse mapping for the loopback address 127.0.0.1
zone "0.0.127.in-addr.arpa" {
     type master;
     file "localhost.rev";
     notify no;
};

    An Authoritative-only Name Server

    This sample configuration is for an authoritative-only server that is the master server for "example.com" and a slave for the subdomain "eng.example.com". 

    options {
     directory "/etc/namedb";           // Working directory
     allow-query-cache { none; };       // Do not allow access to cache
     allow-query { any; };              // This is the default
     recursion no;                      // Do not provide recursive service
};

// Provide a reverse mapping for the loopback address 127.0.0.1
zone "0.0.127.in-addr.arpa" {
     type master;
     file "localhost.rev";
     notify no;
};
// We are the master server for example.com
zone "example.com" {
     type master;
     file "example.com.db";
     // IP addresses of slave servers allowed to transfer example.com
     allow-transfer {
          192.168.4.14;
          192.168.5.53;
     };
};
// We are a slave server for eng.example.com
zone "eng.example.com" {
     type slave;
     file "eng.example.com.bk";
     // IP address of eng.example.com master server
     masters { 192.168.4.12; };
};

    Load Balancing

    A primitive form of load balancing can be achieved in the DNS by using multiple records (such as multiple A records) for one name.

    For example, if you have three WWW servers with network addresses of 10.0.0.1, 10.0.0.2 and 10.0.0.3, a set of records such as the following means that clients will connect to each machine one third of the time:

    Name

    TTL

    CLASS

    TYPE

    Resource Record (RR) Data

    www

    600

    IN

    A

    10.0.0.1

    600

    IN

    A

    10.0.0.2

    600

    IN

    A

    10.0.0.3

    When a resolver queries for these records, BIND will rotate them and respond to the query with the records in a different order. In the example above, clients will randomly receive records in the order 1, 2, 3; 2, 3, 1; and 3, 1, 2. Most clients will use the first record returned and discard the rest.

    For more detail on ordering responses, check the rrset-order sub-statement in the options statement, see RRset Ordering.

    Name Server Operations

    Tools for Use With the Name Server Daemon

    This section describes several indispensable diagnostic, administrative and monitoring tools available to the system administrator for controlling and debugging the name server daemon.

    Diagnostic Tools

    The dig, host, and nslookup programs are all command line tools for manually querying name servers. They differ in style and output format.

    dig

    The domain information groper (dig) is the most versatile and complete of these lookup tools. It has two modes: simple interactive mode for a single query, and batch mode which executes a query for each in a list of several query lines. All query options are accessible from the command line.

    dig [@server] domain [query-type] [query-class] [+query-option] [-dig-option] [%comment]

    The usual simple use of dig will take the form

    dig @server domain query-type query-class

    For more information and a list of available commands and options, see the dig man page.

    host

    The host utility emphasizes simplicity and ease of use. By default, it converts between host names and Internet addresses, but its functionality can be extended with the use of options.

    host [-aCdlnrsTwv] [-c class] [-N ndots] [-t type] [-W timeout] [-R retries] [-m flag] [-4] [-6] hostname [server]

    For more information and a list of available commands and options, see the host man page.

    nslookup

    nslookup has two modes: interactive and non-interactive. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. Non-interactive mode is used to print just the name and requested information for a host or domain.

    nslookup [-option...] [[host-to-find] | [- [server]]]

    Interactive mode is entered when no arguments are given (the default name server will be used) or when the first argument is a hyphen (`-') and the second argument is the host name or Internet address of a name server.

    Non-interactive mode is used when the name or Internet address of the host to be looked up is given as the first argument. The optional second argument specifies the host name or address of a name server.

    Due to its arcane user interface and frequently inconsistent behavior, we do not recommend the use of nslookup. Use dig instead.

    Administrative Tools

    Administrative tools play an integral part in the management of a server.

    named-checkconf

    The named-checkconf program checks the syntax of a named.conf file.

    named-checkconf [-jvz] [-t directory] [filename]

    named-checkzone

    The named-checkzone program checks a master file for syntax and consistency.

    named-checkzone [-djqvD] [-c class] [-o output] [-t directory] [-w directory] [-k (ignore|warn|fail)] [-n (ignore|warn|fail)] [-W (ignore|warn)] zone [filename]

    named-compilezone

    Similar to named-checkzone, but it always dumps the zone content to a specified file (typically in a different format).

    rndc

    The remote name daemon control (rndc) program allows the system administrator to control the operation of a name server. Since BIND 9.2, rndc supports all the commands of the BIND 8 ndc utility except ndc start and ndc restart, which were also not supported in ndc's channel mode. If you run rndc without any options it will display a usage message as follows:

    rndc [-c config] [-s server] [-p port] [-y key] command [command...]

    The command is one of the following:

    reload

    Reload configuration file and zones.

    reload zone [class [view]]

    Reload the given zone.

    refresh zone [class [view]]

    Schedule zone maintenance for the given zone.

    retransfer zone [class [view]]

    Retransfer the given zone from the master.

    freeze [zone [class [view]]]

    Suspend updates to a dynamic zone. If no zone is specified, then all zones are suspended. This allows manual edits to be made to a zone normally updated by dynamic update. It also causes changes in the journal file to be synced into the master and the journal file to be removed. All dynamic update attempts will be refused while the zone is frozen.

    thaw [zone [class [view]]]

    Enable updates to a frozen dynamic zone. If no zone is specified, then all frozen zones are enabled. This causes the server to reload the zone from disk, and re-enables dynamic updates after the load has completed. After a zone is thawed, dynamic updates will no longer be refused.

    notify zone [class [view]]

    Resend NOTIFY messages for the zone.

    reconfig

    Reload the configuration file and load new zones, but do not reload existing zone files even if they have changed. This is faster than a full reload when there is a large number of zones because it avoids the need to examine the modification times of the zones files.

    stats

    Write server statistics to the statistics file.

    querylog

    Toggle query logging. Query logging can also be enabled by explicitly directing the queries category to a channel in the logging section of named.conf or by specifying querylog yes; in the options section of named.conf.

    dumpdb [-all|-cache|-zone] [view ...]

    Dump the server's caches (default) and/or zones to the dump file for the specified views. If no view is specified, all views are dumped.

    stop [-p]

    Stop the server, making sure any recent changes made through dynamic update or IXFR are first saved to the master files of the updated zones. If -p is specified named's process id is returned. This allows an external process to determine when named had completed stopping.

    halt [-p]

    Stop the server immediately. Recent changes made through dynamic update or IXFR are not saved to the master files, but will be rolled forward from the journal files when the server is restarted. If -p is specified named's process id is returned. This allows an external process to determine when named had completed halting.

    trace

    Increment the servers debugging level by one.

    trace level

    Sets the server's debugging level to an explicit value.

    notrace

    Sets the server's debugging level to 0.

    flush

    Flushes the server's cache.

    flushname name

    Flushes the given name from the server's cache.

    status

    Display status of the server. Note that the number of zones includes the internal bind/CH zone and the default ./IN hint zone if there is not an explicit root zone configured.

    tsig-list

    List the names of all TSIG keys currently configured for use by named in each view. The list both statically configured keys and dynamic TKEY-negotiated keys.

    tsig-delete keyname [view]

    Delete a given TKEY-negotated key from the server. (This does not apply to statically configured TSIG keys.)

    recursing

    Dump the list of queries named is currently recursing on.

    validation [on|off] [view ...]

    Enable or disable DNSSEC validation. Note dnssec-enable also needs to be set to yes to be effective. It defaults to enabled.

    A configuration file is required, since all communication with the server is authenticated with digital signatures that rely on a shared secret, and there is no way to provide that secret other than with a configuration file. The default location for the rndc configuration file is /etc/rndc.conf, but an alternate location can be specified with the -c option. If the configuration file is not found, rndc will also look in /etc/rndc.key (or whatever sysconfdir was defined when the BIND build was configured). The rndc.key file is generated by running rndc-confgen -a as described in the section called “controls Statement Definition and Usage”.

    The format of the configuration file is similar to that of named.conf, but limited to only four statements, the options, key, server and include statements. These statements are what associate the secret keys to the servers with which they are meant to be shared. The order of statements is not significant.

    The options statement has three clauses: default-server, default-key, and default-port. default-server takes a host name or address argument and represents the server that will be contacted if no -s option is provided on the command line. default-key takes the name of a key as its argument, as defined by a key statement. default-port specifies the port to which rndc should connect if no port is given on the command line or in a server statement.

    The key statement defines a key to be used by rndc when authenticating with named. Its syntax is identical to the key statement in named.conf. The keyword key is followed by a key name, which must be a valid domain name, though it need not actually be hierarchical; thus, a string like "rndc_key" is a valid name. The key statement has two clauses: algorithm and secret. While the configuration parser will accept any string as the argument to algorithm, currently only the string "hmac-md5" has any meaning. The secret is a base-64 encoded string as specified in RFC 3548.

    The server statement associates a key defined using the key statement with a server. The keyword server is followed by a host name or address. The server statement has two clauses: key and port. The key clause specifies the name of the key to be used when communicating with this server, and the port clause can be used to specify the port rndc should connect to on the server.

    A sample minimal configuration file is as follows: 

    key rndc_key {
     algorithm "hmac-md5";
     secret "c3Ryb25nIGVub3VnaCBmb3IgYSBtYW4gYnV0IG1hZGUgZm9yIGEgd29tYW4K";
};
options {
     default-server 127.0.0.1;
     default-key    rndc_key;
};

    This file, if installed as /etc/rndc.conf, would allow the command:

    $ rndc reload

    to connect to 127.0.0.1 port 953 and cause the name server to reload, if a name server on the local machine were running with following controls statements: 

    controls {
        inet 127.0.0.1 allow { localhost; } keys { rndc_key; };
};

    and it had an identical key statement for rndc_key.

    Running the rndc-confgen program will conveniently create a rndc.conf file for you, and also display the corresponding controls statement that you need to add to named.conf. Alternatively, you can run rndc-confgen -a to set up a rndc.key file and not modify named.conf at all.

    Signals

    Certain UNIX signals cause the name server to take specific actions, as described in the following table. These signals can be sent using the kill command.

    SIGHUP

    Causes the server to read named.conf and reload the database.

    SIGTERM

    Causes the server to clean up and exit.

    SIGINT

    Causes the server to clean up and exit.

    Notify

    DNS NOTIFY is a mechanism that allows master servers to notify their slave servers of changes to a zone's data. In response to a NOTIFY from a master server, the slave will check to see that its version of the zone is the current version and, if not, initiate a zone transfer.

    For more information about DNS NOTIFY, see the description of the notify option in the section called “Boolean Options” and the description of the zone option also-notify in the section called “Zone Transfers”. The NOTIFY protocol is specified in RFC 1996.

    Note

    As a slave zone can also be a master to other slaves, named, by default, sends NOTIFY messages for every zone it loads. Specifying notify master-only; will cause named to only send NOTIFY for master zones that it loads.

    Dynamic Update

    Dynamic Update is a method for adding, replacing or deleting records in a master server by sending it a special form of DNS messages. The format and meaning of these messages is specified in RFC 2136.

    Dynamic update is enabled by including an allow-update or update-policy clause in the zone statement. The tkey-gssapi-credential and tkey-domain clauses in the options statement enable the server to negotiate keys that can be matched against those in update-policy or allow-update.

    Updating of secure zones (zones using DNSSEC) follows RFC 3007: RRSIG, NSEC and NSEC3 records affected by updates are automatically regenerated by the server using an online zone key. Update authorization is based on transaction signatures and an explicit server policy.

    The journal file

    All changes made to a zone using dynamic update are stored in the zone's journal file. This file is automatically created by the server when the first dynamic update takes place. The name of the journal file is formed by appending the extension .jnl to the name of the corresponding zone file unless specifically overridden. The journal file is in a binary format and should not be edited manually.

    The server will also occasionally write ("dump") the complete contents of the updated zone to its zone file. This is not done immediately after each dynamic update, because that would be too slow when a large zone is updated frequently. Instead, the dump is delayed by up to 15 minutes, allowing additional updates to take place. During the dump process, transient files will be created with the extensions .jnw and .jbk; under ordinary circumstances, these will be removed when the dump is complete, and can be safely ignored.

    When a server is restarted after a shutdown or crash, it will replay the journal file to incorporate into the zone any updates that took place after the last zone dump.

    Changes that result from incoming incremental zone transfers are also journalled in a similar way.

    The zone files of dynamic zones cannot normally be edited by hand because they are not guaranteed to contain the most recent dynamic changes — those are only in the journal file. The only way to ensure that the zone file of a dynamic zone is up to date is to run rndc stop.

    If you have to make changes to a dynamic zone manually, the following procedure will work: Disable dynamic updates to the zone using rndc freeze zone. This will also remove the zone's .jnl file and update the master file. Edit the zone file. Run rndc thaw zone to reload the changed zone and re-enable dynamic updates.

    Incremental Zone Transfers (IXFR)

    The incremental zone transfer (IXFR) protocol is a way for slave servers to transfer only changed data, instead of having to transfer the entire zone. The IXFR protocol is specified in RFC 1995. See Proposed Standards.

    When acting as a master, BIND 9 supports IXFR for those zones where the necessary change history information is available. These include master zones maintained by dynamic update and slave zones whose data was obtained by IXFR. For manually maintained master zones, and for slave zones obtained by performing a full zone transfer (AXFR), IXFR is supported only if the option ixfr-from-differences is set to yes.

    When acting as a slave, BIND 9 will attempt to use IXFR unless it is explicitly disabled via the request-ixfr option or the use of ixfr-from-differences. For more information about disabling IXFR, see the description of the request-ixfr clause of the server statement.

    Split DNS

    Setting up different views, or visibility, of the DNS space to internal and external resolvers is usually referred to as a Split DNS setup. There are several reasons an organization would want to set up its DNS this way.

    One common reason for setting up a DNS system this way is to hide "internal" DNS information from "external" clients on the Internet. There is some debate as to whether or not this is actually useful. Internal DNS information leaks out in many ways (via email headers, for example) and most savvy "attackers" can find the information they need using other means. However, since listing addresses of internal servers that external clients cannot possibly reach can result in connection delays and other annoyances, an organization may choose to use a Split DNS to present a consistent view of itself to the outside world.

    Another common reason for setting up a Split DNS system is to allow internal networks that are behind filters or in RFC 1918 space (reserved IP space, as documented in RFC 1918) to resolve DNS on the Internet. Split DNS can also be used to allow mail from outside back in to the internal network.

    Example split DNS setup

    Let's say a company named Example, Inc. (example.com) has several corporate sites that have an internal network with reserved Internet Protocol (IP) space and an external demilitarized zone (DMZ), or "outside" section of a network, that is available to the public.

    Example, Inc. wants its internal clients to be able to resolve external hostnames and to exchange mail with people on the outside. The company also wants its internal resolvers to have access to certain internal-only zones that are not available at all outside of the internal network.

    In order to accomplish this, the company will set up two sets of name servers. One set will be on the inside network (in the reserved IP space) and the other set will be on bastion hosts, which are "proxy" hosts that can talk to both sides of its network, in the DMZ.

    The internal servers will be configured to forward all queries, except queries for site1.internal, site2.internal, site1.example.com, and site2.example.com, to the servers in the DMZ. These internal servers will have complete sets of information for site1.example.com, site2.example.com, site1.internal, and site2.internal.

    To protect the site1.internal and site2.internal domains, the internal name servers must be configured to disallow all queries to these domains from any external hosts, including the bastion hosts.

    The external servers, which are on the bastion hosts, will be configured to serve the "public" version of the site1 and site2.example.com zones. This could include things such as the host records for public servers (www.example.com and ftp.example.com), and mail exchange (MX) records (a.mx.example.com and b.mx.example.com).

    In addition, the public site1 and site2.example.com zones should have special MX records that contain wildcard (`*') records pointing to the bastion hosts. This is needed because external mail servers do not have any other way of looking up how to deliver mail to those internal hosts. With the wildcard records, the mail will be delivered to the bastion host, which can then forward it on to internal hosts.

    Here's an example of a wildcard MX record: 

    *   IN MX 10 external1.example.com.

    Now that they accept mail on behalf of anything in the internal network, the bastion hosts will need to know how to deliver mail to internal hosts. In order for this to work properly, the resolvers on the bastion hosts will need to be configured to point to the internal name servers for DNS resolution.

    Queries for internal hostnames will be answered by the internal servers, and queries for external hostnames will be forwarded back out to the DNS servers on the bastion hosts.

    In order for all this to work properly, internal clients will need to be configured to query only the internal name servers for DNS queries. This could also be enforced via selective filtering on the network.

    If everything has been set properly, Example, Inc.'s internal clients will now be able to:

    • Look up any hostnames in the site1 and site2.example.com zones.
    • Look up any hostnames in the site1.internal and site2.internal domains.
    • Look up any hostnames on the Internet.
    • Exchange mail with both internal and external people.

    Hosts on the Internet will be able to:

    • Look up any hostnames in the site1 and site2.example.com zones.
    • Exchange mail with anyone in the site1 and site2.example.com zones.

    Here is an example configuration for the setup we just described above. Note that this is only configuration information; for information on how to configure your zone files, see the section called “Sample Configurations”.

acl internals { 172.16.72.0/24; 192.168.1.0/24; };

acl externals { bastion-ips-go-here; };

options {

    forwarders {                                // forward to external servers
        bastion-ips-go-here;
    };
    allow-transfer { none; };                   // sample allow-transfer (no one)
    allow-query { internals; externals; };      // restrict query access
    allow-recursion { internals; };             // restrict recursion
    ...
    ...
};

  allow-query-cache { internals; externals; };  // restrict cache access
  allow-recursion { internals; externals; };    // restrict recursion
  ...
  ...
};

    TSIG

    This is a short guide to setting up Transaction SIGnatures (TSIG) based transaction security in BIND. It describes changes to the configuration file as well as what changes are required for different features, including the process of creating transaction keys and using transaction signatures with BIND.

    BIND primarily supports TSIG for server to server communication. This includes zone transfer, notify, and recursive query messages. Resolvers based on newer versions of BIND 8 have limited support for TSIG.

    TSIG can also be useful for dynamic update. A primary server for a dynamic zone should control access to the dynamic update service, but IP-based access control is insufficient. The cryptographic access control provided by TSIG is far superior. The nsupdate program supports TSIG via the -k and -y command line options or inline by use of the key.

    Generate Shared Keys for Each Pair of Hosts

    A shared secret is generated to be shared between host1 and host2. An arbitrary key name is chosen: "host1-host2.". The key name must be the same on both hosts.

    Automatic Generation

    The following command will generate a 128-bit (16 byte) HMAC-SHA256 key as described above. Longer keys are better, but shorter keys are easier to read. Note that the maximum key length is the digest length, here 256 bits.

    dnssec-keygen -a hmac-sha256 -b 128 -n HOST host1-host2.

    The key is in the file Khost1-host2.+163+00000.private. Nothing directly uses this file, but the base-64 encoded string following "Key:" can be extracted from the file and used as a shared secret: 

    Key: La/E5CjG9O+os1jq0a2jdA==

    The string "La/E5CjG9O+os1jq0a2jdA==" can be used as the shared secret.

    Manual Generation

    The shared secret is simply a random sequence of bits, encoded in base-64. Most ASCII strings are valid base-64 strings (assuming the length is a multiple of 4 and only valid characters are used), so the shared secret can be manually generated.

    Also, a known string can be run through mmencode or a similar program to generate base-64 encoded data.

    Copying the Shared Secret to Both Machines

    This is beyond the scope of DNS. A secure transport mechanism should be used. This could be secure FTP, ssh, telephone, etc.

    Informing the Servers of the Key's Existence

    Imagine host1 and host 2 are both servers. The following is added to each server's named.conf file: 

    key host1-host2. {
  algorithm hmac-sha256;
  secret "La/E5CjG9O+os1jq0a2jdA==";
};

    The secret is the one generated above. Since this is a secret, it is recommended that either named.conf be non-world readable, or the key directive be added to a non-world readable file that is included by named.conf.

    At this point, the key is recognized. This means that if the server receives a message signed by this key, it can verify the signature. If the signature is successfully verified, the response is signed by the same key.

    Instructing the Server to Use the Key

    Since keys are shared between two hosts only, the server must be told when keys are to be used. The following is added to the named.conf file for host1, if the IP address of host2 is 10.1.2.3: 

    server 10.1.2.3 {
  keys { host1-host2. ;};
};

    Multiple keys may be present, but only the first is used. This directive does not contain any secrets, so it may be in a world-readable file.

    If host1 sends a message that is a request to that address, the message will be signed with the specified key. host1 will expect any responses to signed messages to be signed with the same key.

    A similar statement must be present in host2's configuration file (with host1's address) for host2 to sign request messages to host1.

    TSIG Key Based Access Control

    BIND allows IP addresses and ranges to be specified in ACL definitions and allow-{ query | transfer | update } directives. This has been extended to allow TSIG keys also. The above key would be denoted key host1-host2.

    An example of an allow-update directive would be: 

    allow-update { key host1-host2. ;};

    This allows dynamic updates to succeed only if the request was signed by a key named "host1-host2.".

    You may want to read about the more powerful update-policy statement in the section called “Dynamic Update Policies”.

    Errors

    The processing of TSIG signed messages can result in several errors. If a signed message is sent to a non-TSIG aware server, a FORMERR (format error) will be returned, since the server will not understand the record. This is a result of misconfiguration, since the server must be explicitly configured to send a TSIG signed message to a specific server.

    If a TSIG aware server receives a message signed by an unknown key, the response will be unsigned with the TSIG extended error code set to BADKEY. If a TSIG aware server receives a message with a signature that does not validate, the response will be unsigned with the TSIG extended error code set to BADSIG. If a TSIG aware server receives a message with a time outside of the allowed range, the response will be signed with the TSIG extended error code set to BADTIME, and the time values will be adjusted so that the response can be successfully verified. In any of these cases, the message's rcode (response code) is set to NOTAUTH (not authenticated).

    TKEY

    TKEY is a mechanism for automatically generating a shared secret between two hosts. There are several "modes" of TKEY that specify how the key is generated or assigned. BIND 9 implements only one of these modes, the Diffie-Hellman key exchange. Both hosts are required to have a Diffie-Hellman KEY record (although this record is not required to be present in a zone). The TKEY process must use signed messages, signed either by TSIG or SIG(0). The result of TKEY is a shared secret that can be used to sign messages with TSIG. TKEY can also be used to delete shared secrets that it had previously generated.

    The TKEY process is initiated by a client or server by sending a signed TKEY query (including any appropriate KEYs) to a TKEY-aware server. The server response, if it indicates success, will contain a TKEY record and any appropriate keys. After this exchange, both participants have enough information to determine the shared secret; the exact process depends on the TKEY mode. When using the Diffie-Hellman TKEY mode, Diffie-Hellman keys are exchanged, and the shared secret is derived by both participants.

    SIG(0)

    BIND 9 partially supports DNSSEC SIG(0) transaction signatures as specified in RFC 2535 and RFC 2931. SIG(0) uses public/private keys to authenticate messages. Access control is performed in the same manner as TSIG keys; privileges can be granted or denied based on the key name.

    When a SIG(0) signed message is received, it will only be verified if the key is known and trusted by the server; the server will not attempt to locate and/or validate the key.

    SIG(0) signing of multiple-message TCP streams is not supported.

    The only tool shipped with BIND 9 that generates SIG(0) signed messages is nsupdate.

    DNSSEC

    Cryptographic authentication of DNS information is possible through the DNS Security (DNSSEC-bis) extensions, defined in RFC 4033, RFC 4034, and RFC 4035. This section describes the creation and use of DNSSEC signed zones.

    In order to set up a DNSSEC secure zone, there are a series of steps which must be followed. BIND 9 ships with several tools that are used in this process, which are explained in more detail below. In all cases, the -h option prints a full list of parameters. Note that the DNSSEC tools require the keyset files to be in the working directory or the directory specified by the -d option, and that the tools shipped with BIND 9.2.x and earlier are not compatible with the current ones.

    There must also be communication with the administrators of the parent and/or child zone to transmit keys. A zone's security status must be indicated by the parent zone for a DNSSEC capable resolver to trust its data. This is done through the presence or absence of a DS record at the delegation point.

    For other servers to trust data in this zone, they must either be statically configured with this zone's zone key or the zone key of another zone above this one in the DNS tree.

    Generating Keys

    The dnssec-keygen program is used to generate keys.

    A secure zone must contain one or more zone keys. The zone keys will sign all other records in the zone, as well as the zone keys of any secure delegated zones. Zone keys must have the same name as the zone, a name type of ZONE, and must be usable for authentication. It is recommended that zone keys use a cryptographic algorithm designated as "mandatory to implement" by the IETF; currently the only one is RSASHA1.

    The following command will generate a 768-bit RSASHA1 key for the child.example zone:

    dnssec-keygen -a RSASHA1 -b 768 -n ZONE child.example.

    Two output files will be produced: Kchild.example.+005+12345.key and Kchild.example.+005+12345.private (where 12345 is an example of a key tag). The key filenames contain the key name (child.example.), algorithm (3 is DSA, 1 is RSAMD5, 5 is RSASHA1, etc.), and the key tag (12345 in this case). The private key (in the .private file) is used to generate signatures, and the public key (in the .key file) is used for signature verification.

    To generate another key with the same properties (but with a different key tag), repeat the above command.

    The dnssec-keyfromlabel program is used to get a key pair from a crypto hardware and build the key files. Its usage is similar to dnssec-keygen.

    The public keys should be inserted into the zone file by including the .key files using $INCLUDE statements.

    Signing the Zone

    The dnssec-signzone program is used to sign a zone.

    Any keyset files corresponding to secure subzones should be present. The zone signer will generate NSEC, NSEC3 and RRSIG records for the zone, as well as DS for the child zones if '-g' is specified. If '-g' is not specified, then DS RRsets for the secure child zones need to be added manually.

    The following command signs the zone, assuming it is in a file called zone.child.example. By default, all zone keys which have an available private key are used to generate signatures.

    dnssec-signzone -o child.example zone.child.example

    One output file is produced: zone.child.example.signed. This file should be referenced by named.conf as the input file for the zone.

    dnssec-signzone will also produce a keyset and dsset files and optionally a dlvset file. These are used to provide the parent zone administrators with the DNSKEYs (or their corresponding DS records) that are the secure entry point to the zone.

    Configuring Servers

    To enable named to respond appropriately to DNS requests from DNSSEC aware clients, dnssec-enable must be set to yes. (This is the default setting.)

    To enable named to validate answers from other servers, the dnssec-enable and dnssec-validation options must both be set to yes (the default setting in BIND 9.5 and later), and at least one trust anchor must be configured with a trusted-keys statement in named.conf.

    trusted-keys are copies of DNSKEY RRs for zones that are used to form the first link in the cryptographic chain of trust. All keys listed in trusted-keys (and corresponding zones) are deemed to exist and only the listed keys will be used to validated the DNSKEY RRset that they are from.

    trusted-keys are described in more detail later in this document.

    Unlike BIND 8, BIND 9 does not verify signatures on load, so zone keys for authoritative zones do not need to be specified in the configuration file.

    After DNSSEC gets established, a typical DNSSEC configuration will look something like the following. It has a one or more public keys for the root. This allows answers from outside the organization to be validated. It will also have several keys for parts of the namespace the organization controls. These are here to ensure that named is immune to compromises in the DNSSEC components of the security of parent zones.

        dnssec-enable yes;
        dnssec-validation yes;
};

    Note

    None of the keys listed in this example are valid. In particular, the root key is not valid.

    When DNSSEC validation is enabled and properly configured, the resolver will reject any answers from signed, secure zones which fail to validate, and will return SERVFAIL to the client.

    Responses may fail to validate for any of several reasons, including missing, expired, or invalid signatures, a key which does not match the DS RRset in the parent zone, or an insecure response from a zone which, according to its parent, should have been secure.

    Note

    When the validator receives a response from an unsigned zone that has a signed parent, it must confirm with the parent that the zone was intentionally left unsigned. It does this by verifying, via signed and validated NSEC/NSEC3 records, that the parent zone contains no DS records for the child.

    If the validator can prove that the zone is insecure, then the response is accepted. However, if it cannot, then it must assume an insecure response to be a forgery; it rejects the response and logs an error.

    The logged error reads "insecurity proof failed" and "got insecure response; parent indicates it should be secure". (Prior to BIND 9.7, the logged error was "not insecure". This referred to the zone, not the response.)

    IPv6 Support in BIND 9

    BIND 9 fully supports all currently defined forms of IPv6 name to address and address to name lookups. It will also use IPv6 addresses to make queries when running on an IPv6 capable system.

    For forward lookups, BIND 9 supports only AAAA records. RFC 3363 deprecated the use of A6 records, and client-side support for A6 records was accordingly removed from BIND 9. However, authoritative BIND 9 name servers still load zone files containing A6 records correctly, answer queries for A6 records, and accept zone transfer for a zone containing A6 records.

    For IPv6 reverse lookups, BIND 9 supports the traditional "nibble" format used in the ip6.arpa domain, as well as the older, deprecated ip6.int domain. Older versions of BIND 9 supported the "binary label" (also known as "bitstring") format, but support of binary labels has been completely removed per RFC 3363. Many applications in BIND 9 do not understand the binary label format at all any more, and will return an error if given. In particular, an authoritative BIND 9 name server will not load a zone file containing binary labels.

    For an overview of the format and structure of IPv6 addresses, see the section called “IPv6 addresses (AAAA)”.

    Address Lookups Using AAAA Records

    The IPv6 AAAA record is a parallel to the IPv4 A record, and, unlike the deprecated A6 record, specifies the entire IPv6 address in a single record. For example, 

    $ORIGIN example.com.
host            3600    IN      AAAA    2001:db8::1

    Use of IPv4-in-IPv6 mapped addresses is not recommended. If a host has an IPv4 address, use an A record, not a AAAA, with ::ffff:192.168.42.1 as the address.

    Address to Name Lookups Using Nibble Format

    When looking up an address in nibble format, the address components are simply reversed, just as in IPv4, and ip6.arpa. is appended to the resulting name. For example, the following would provide reverse name lookup for a host with address 2001:db8::1. 

    $ORIGIN 0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0   14400 IN      PTR     host.example.com.

    The Lightweight Resolver Library
    Running a Resolver Daemon

    The Lightweight Resolver Library

    Traditionally applications have been linked with a stub resolver library that sends recursive DNS queries to a local caching name server.

    IPv6 once introduced new complexity into the resolution process, such as following A6 chains and DNAME records, and simultaneous lookup of IPv4 and IPv6 addresses. Though most of the complexity was then removed, these are hard or impossible to implement in a traditional stub resolver.

    BIND 9 therefore can also provide resolution services to local clients using a combination of a lightweight resolver library and a resolver daemon process running on the local host. These communicate using a simple UDP-based protocol, the "lightweight resolver protocol" that is distinct from and simpler than the full DNS protocol.

    Running a Resolver Daemon

    To use the lightweight resolver interface, the system must run the resolver daemon lwresd or a local name server configured with a lwres statement.

    By default, applications using the lightweight resolver library will make UDP requests to the IPv4 loopback address (127.0.0.1) on port 921. The address can be overridden by lwserver lines in /etc/resolv.conf.

    The daemon currently only looks in the DNS, but in the future it may use other sources such as /etc/hosts, NIS, etc.

    The lwresd daemon is essentially a caching-only name server that responds to requests using the lightweight resolver protocol rather than the DNS protocol. Because it needs to run on each host, it is designed to require no or minimal configuration. Unless configured otherwise, it uses the name servers listed on nameserver lines in /etc/resolv.conf as forwarders, but is also capable of doing the resolution autonomously if none are specified.

    The lwresd daemon may also be configured with a named.conf style configuration file, in /etc/lwresd.conf by default. A name server may also be configured to act as a lightweight resolver daemon using the lwres statement in named.conf.

    BIND 9 configuration is broadly similar to BIND 8; however, there are a few new areas of configuration, such as views. BIND 8 configuration files should work with few alterations in BIND 9, although more complex configurations should be reviewed to check if they can be more efficiently implemented using the new features found in BIND 9.

    BIND 4 configuration files can be converted to the new format using the shell script contrib/named-bootconf/named-bootconf.sh.

    Configuration File Elements

    Following is a list of elements used throughout the BIND configuration file documentation:

    acl_name

    The name of an address_match_list as defined by the acl statement.

    address_match_list

    A list of one or more ip_addr, ip_prefix, key_id, or acl_name elements, see the section called “Address Match Lists”.

    masters_list

    A named list of one or more ip_addr with optional key_id and/or ip_port. A masters_list may include other masters_lists.

    domain_name

    A quoted string which will be used as a DNS name, for example "my.test.domain".

    dotted_decimal

    One to four integers valued 0 through 255 separated by dots (`.'), such as 123, 45.67 or 89.123.45.67.

    ip4_addr

    An IPv4 address with exactly four elements in dotted_decimal notation.

    ip6_addr

    An IPv6 address, such as 2001:db8::1234. IPv6 scoped addresses that have ambiguity on their scope zones must be disambiguated by an appropriate zone ID with the percent character (`%') as delimiter. It is strongly recommended to use string zone names rather than numeric identifiers, in order to be robust against system configuration changes. However, since there is no standard mapping for such names and identifier values, currently only interface names as link identifiers are supported, assuming one-to-one mapping between interfaces and links. For example, a link-local address fe80::1 on the link attached to the interface ne0 can be specified as fe80::1%ne0. Note that on most systems link-local addresses always have the ambiguity, and need to be disambiguated.

    ip_addr

    An ip4_addr or ip6_addr.

    ip_port

    An IP port number. The number is limited to 0 through 65535, with values below 1024 typically restricted to use by processes running as root. In some cases, an asterisk (`*') character can be used as a placeholder to select a random high-numbered port.

    ip_prefix

    An IP network specified as an ip_addr, followed by a slash (`/') and then the number of bits in the netmask. Trailing zeros in a ip_addr may omitted. For example, 127/8 is the network 127.0.0.0 with netmask 255.0.0.0 and 1.2.3.0/28 is network 1.2.3.0 with netmask 255.255.255.240.

    When specifying a prefix involving a IPv6 scoped address the scope may be omitted. In that case the prefix will match packets from any scope.

    key_id

    A domain_name representing the name of a shared key, to be used for transaction security.

    key_list

    A list of one or more key_ids, separated by semicolons and ending with a semicolon.

    number

    A non-negative 32-bit integer (i.e., a number between 0 and 4294967295, inclusive). Its acceptable value might further be limited by the context in which it is used.

    path_name

    A quoted string which will be used as a pathname, such as zones/master/my.test.domain.

    port_list

    A list of an ip_port or a port range. A port range is specified in the form of range followed by two ip_ports, port_low and port_high, which represents port numbers from port_low through port_high, inclusive. port_low must not be larger than port_high. For example, range 1024 65535 represents ports from 1024 through 65535. In either case an asterisk (`*') character is not allowed as a valid ip_port.

    size_spec

    A number, the word unlimited, or the word default.

    An unlimited size_spec requests unlimited use, or the maximum available amount. A default size_spec uses the limit that was in force when the server was started.

    A number can optionally be followed by a scaling factor: K or k for kilobytes, M or m for megabytes, and G or g for gigabytes, which scale by 1024, 1024*1024, and 1024*1024*1024 respectively.

    The value must be representable as a 64-bit unsigned integer (0 to 18446744073709551615, inclusive). Using unlimited is the best way to safely set a really large number.

    yes_or_no

    Either yes or no. The words true and false are also accepted, as are the numbers 1 and 0.

    dialup_option

    One of yes, no, notify, notify-passive, refresh or passive. When used in a zone, notify-passive, refresh, and passive are restricted to slave and stub zones.

    Address Match Lists

    Syntax

    address_match_list = address_match_list_element ;
  [ address_match_list_element; ... ]
address_match_list_element = [ ! ] (ip_address [/length] |
   key key_id | acl_name | { address_match_list } )

    Definition and Usage

    Address match lists are primarily used to determine access control for various server operations. They are also used in the listen-on and sortlist statements. The elements which constitute an address match list can be any of the following:

    • an IP address (IPv4 or IPv6)
    • an IP prefix (in `/' notation)
    • a key ID, as defined by the key statement
    • the name of an address match list defined with the acl statement
    • a nested address match list enclosed in braces

    Elements can be negated with a leading exclamation mark (`!'), and the match list names "any", "none", "localhost", and "localnets" are predefined. More information on those names can be found in the description of the acl statement.

    The addition of the key clause made the name of this syntactic element something of a misnomer, since security keys can be used to validate access without regard to a host or network address. Nonetheless, the term "address match list" is still used throughout the documentation.

    When a given IP address or prefix is compared to an address match list, the comparison takes place in approximately O(1) time. However, key comparisons require that the list of keys be traversed until a matching key is found, and therefore may be somewhat slower.

    The interpretation of a match depends on whether the list is being used for access control, defining listen-on ports, or in a sortlist, and whether the element was negated.

    When used as an access control list, a non-negated match allows access and a negated match denies access. If there is no match, access is denied. The clauses allow-notify, allow-recursion, allow-recursion-on, allow-query, allow-query-on, allow-query-cache, allow-query-cache-on, allow-transfer, allow-update, allow-update-forwarding, and blackhole all use address match lists. Similarly, the listen-on option will cause the server to refuse queries on any of the machine's addresses which do not match the list.

    Order of insertion is significant. If more than one element in an ACL is found to match a given IP address or prefix, preference will be given to the one that came first in the ACL definition. Because of this first-match behavior, an element that defines a subset of another element in the list should come before the broader element, regardless of whether either is negated. For example, in 1.2.3/24; ! 1.2.3.13; the 1.2.3.13 element is completely useless because the algorithm will match any lookup for 1.2.3.13 to the 1.2.3/24 element. Using ! 1.2.3.13; 1.2.3/24 fixes that problem by having 1.2.3.13 blocked by the negation, but all other 1.2.3.* hosts fall through.

    Comment Syntax

    The BIND 9 comment syntax allows for comments to appear anywhere that whitespace may appear in a BIND configuration file. To appeal to programmers of all kinds, they can be written in the C, C++, or shell/perl style.

    Syntax

    /* This is a BIND comment as in C */

    // This is a BIND comment as in C++

    # This is a BIND comment as in common UNIX shells and perl

    Definition and Usage

    Comments may appear anywhere that whitespace may appear in a BIND configuration file.

    C-style comments start with the two characters /* (slash, star) and end with */ (star, slash). Because they are completely delimited with these characters, they can be used to comment only a portion of a line or to span multiple lines.

    C-style comments cannot be nested. For example, the following is not valid because the entire comment ends with the first */: 

    /* This is the start of a comment.
   This is still part of the comment.
/* This is an incorrect attempt at nesting a comment. */
   This is no longer in any comment. */

    C++-style comments start with the two characters // (slash, slash) and continue to the end of the physical line. They cannot be continued across multiple physical lines; to have one logical comment span multiple lines, each line must use the // pair. For example: 

    // This is the start of a comment.  The next line
// is a new comment, even though it is logically
// part of the previous comment.

    Shell-style (or perl-style, if you prefer) comments start with the character # (number sign) and continue to the end of the physical line, as in C++ comments. For example: 

    # This is the start of a comment.  The next line
# is a new comment, even though it is logically
# part of the previous comment.

    Warning

    You cannot use the semicolon (`;') character to start a comment such as you would in a zone file. The semicolon indicates the end of a configuration statement.

    Configuration File Grammar

    A BIND 9 configuration consists of statements and comments. Statements end with a semicolon. Statements and comments are the only elements that can appear without enclosing braces. Many statements contain a block of sub-statements, which are also terminated with a semicolon.

    The following statements are supported:

    acl

    defines a named IP address matching list, for access control and other uses.

    controls

    declares control channels to be used by the rndc utility.

    include

    includes a file.

    key

    specifies key information for use in authentication and authorization using TSIG.

    logging

    specifies what the server logs, and where the log messages are sent.

    lwres

    configures named to also act as a light-weight resolver daemon (lwresd).

    masters

    defines a named masters list for inclusion in stub and slave zone masters clauses.

    options

    controls global server configuration options and sets defaults for other statements.

    server

    sets certain configuration options on a per-server basis.

    statistics-channels

    declares communication channels to get access to named statistics.

    trusted-keys

    defines trusted DNSSEC keys.

    view

    defines a view.

    zone

    defines a zone.

    The logging and options statements may only occur once per configuration.

    acl Statement Grammar

    acl acl-name {
    address_match_list
};

    acl Statement Definition and Usage

    The acl statement assigns a symbolic name to an address match list. It gets its name from a primary use of address match lists: Access Control Lists (ACLs).

    Note that an address match list's name must be defined with acl before it can be used elsewhere; no forward references are allowed.

    The following ACLs are built-in:

    any

    Matches all hosts.

    none

    Matches no hosts.

    localhost

    Matches the IPv4 and IPv6 addresses of all network interfaces on the system.

    localnets

    Matches any host on an IPv4 or IPv6 network for which the system has an interface. Some systems do not provide a way to determine the prefix lengths of local IPv6 addresses. In such a case, localnets only matches the local IPv6 addresses, just like localhost.

    controls Statement Grammar

    controls {
   [ inet ( ip_addr | * ) [ port ip_port ] allow {  address_match_list  }
                keys { key_list }; ]
   [ inet ...; ]
   [ unix path perm number owner number group number keys { key_list }; ]
   [ unix ...; ]
};

    controls Statement Definition and Usage

    The controls statement declares control channels to be used by system administrators to control the operation of the name server. These control channels are used by the rndc utility to send commands to and retrieve non-DNS results from a name server.

    An inet control channel is a TCP socket listening at the specified ip_port on the specified ip_addr, which can be an IPv4 or IPv6 address. An ip_addr of * (asterisk) is interpreted as the IPv4 wildcard address; connections will be accepted on any of the system's IPv4 addresses. To listen on the IPv6 wildcard address, use an ip_addr of ::. If you will only use rndc on the local host, using the loopback address (127.0.0.1 or ::1) is recommended for maximum security.

    If no port is specified, port 953 is used. The asterisk "*" cannot be used for ip_port.

    The ability to issue commands over the control channel is restricted by the allow and keys clauses. Connections to the control channel are permitted based on the address_match_list. This is for simple IP address based filtering only; any key_id elements of the address_match_list are ignored.

    A unix control channel is a UNIX domain socket listening at the specified path in the file system. Access to the socket is specified by the perm, owner and group clauses. Note on some platforms (SunOS and Solaris) the permissions (perm) are applied to the parent directory as the permissions on the socket itself are ignored.

    The primary authorization mechanism of the command channel is the key_list, which contains a list of key_ids. Each key_id in the key_list is authorized to execute commands over the control channel. See Remote Name Daemon Control application in the section called “Administrative Tools”) for information about configuring keys in rndc.

    If no controls statement is present, named will set up a default control channel listening on the loopback address 127.0.0.1 and its IPv6 counterpart ::1. In this case, and also when the controls statement is present but does not have a keys clause, named will attempt to load the command channel key from the file rndc.key in /etc (or whatever sysconfdir was specified as when BIND was built). To create a rndc.key file, run rndc-confgen -a.

    The rndc.key feature was created to ease the transition of systems from BIND 8, which did not have digital signatures on its command channel messages and thus did not have a keys clause. It makes it possible to use an existing BIND 8 configuration file in BIND 9 unchanged, and still have rndc work the same way ndc worked in BIND 8, simply by executing the command rndc-confgen -a after BIND 9 is installed.

    Since the rndc.key feature is only intended to allow the backward-compatible usage of BIND 8 configuration files, this feature does not have a high degree of configurability. You cannot easily change the key name or the size of the secret, so you should make a rndc.conf with your own key if you wish to change those things. The rndc.key file also has its permissions set such that only the owner of the file (the user that named is running as) can access it. If you desire greater flexibility in allowing other users to access rndc commands, then you need to create a rndc.conf file and make it group readable by a group that contains the users who should have access.

    To disable the command channel, use an empty controls statement: controls { };.

    include Statement Grammar

    include filename;

    include Statement Definition and Usage

    The include statement inserts the specified file at the point where the include statement is encountered. The include statement facilitates the administration of configuration files by permitting the reading or writing of some things but not others. For example, the statement could include private keys that are readable only by the name server.

    key Statement Grammar

    key key_id {
    algorithm string;
    secret string;
};

    key Statement Definition and Usage

    The key statement defines a shared secret key for use with TSIG (see the section called “TSIG”) or the command channel (see the section called “controls Statement Definition and Usage”).

    The key statement can occur at the top level of the configuration file or inside a view statement. Keys defined in top-level key statements can be used in all views. Keys intended for use in a controls statement (see the section called “controls Statement Definition and Usage”) must be defined at the top level.

    The key_id, also known as the key name, is a domain name uniquely identifying the key. It can be used in a server statement to cause requests sent to that server to be signed with this key, or in address match lists to verify that incoming requests have been signed with a key matching this name, algorithm, and secret.

    The algorithm_id is a string that specifies a security/authentication algorithm. Named supports hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384 and hmac-sha512 TSIG authentication. Truncated hashes are supported by appending the minimum number of required bits preceded by a dash, e.g. hmac-sha1-80. The secret_string is the secret to be used by the algorithm, and is treated as a base-64 encoded string.

    logging Statement Grammar

    logging {
   [ channel channel_name {
     ( file path_name
         [ versions ( number | unlimited ) ]
         [ size size spec ]
       | syslog syslog_facility
       | stderr
       | null );
     [ severity (critical | error | warning | notice |
                 info | debug [ level ] | dynamic ); ]
     [ print-category yes or no; ]
     [ print-severity yes or no; ]
     [ print-time yes or no; ]
   }; ]
   [ category category_name {
     channel_name ; [ channel_name ; ... ]
   }; ]
   ...
};

    logging Statement Definition and Usage

    The logging statement configures a wide variety of logging options for the name server. Its channel phrase associates output methods, format options and severity levels with a name that can then be used with the category phrase to select how various classes of messages are logged.

    Only one logging statement is used to define as many channels and categories as are wanted. If there is no logging statement, the logging configuration will be: 

    logging {
     category default { default_syslog; default_debug; };
     category unmatched { null; };
};

    In BIND 9, the logging configuration is only established when the entire configuration file has been parsed. In BIND 8, it was established as soon as the logging statement was parsed. When the server is starting up, all logging messages regarding syntax errors in the configuration file go to the default channels, or to standard error if the "-g" option was specified.

    The channel Phrase

    All log output goes to one or more channels; you can make as many of them as you want.

    Every channel definition must include a destination clause that says whether messages selected for the channel go to a file, to a particular syslog facility, to the standard error stream, or are discarded. It can optionally also limit the message severity level that will be accepted by the channel (the default is info), and whether to include a named-generated time stamp, the category name and/or severity level (the default is not to include any).

    The null destination clause causes all messages sent to the channel to be discarded; in that case, other options for the channel are meaningless.

    The file destination clause directs the channel to a disk file. It can include limitations both on how large the file is allowed to become, and how many versions of the file will be saved each time the file is opened.

    If you use the versions log file option, then named will retain that many backup versions of the file by renaming them when opening. For example, if you choose to keep three old versions of the file lamers.log, then just before it is opened lamers.log.1 is renamed to lamers.log.2, lamers.log.0 is renamed to lamers.log.1, and lamers.log is renamed to lamers.log.0. You can say versions unlimited to not limit the number of versions. If a size option is associated with the log file, then renaming is only done when the file being opened exceeds the indicated size. No backup versions are kept by default; any existing log file is simply appended.

    The size option for files is used to limit log growth. If the file ever exceeds the size, then named will stop writing to the file unless it has a versions option associated with it. If backup versions are kept, the files are rolled as described above and a new one begun. If there is no versions option, no more data will be written to the log until some out-of-band mechanism removes or truncates the log to less than the maximum size. The default behavior is not to limit the size of the file.

    Example usage of the size and versions options: 

    channel an_example_channel {
    file "example.log" versions 3 size 20m;
    print-time yes;
    print-category yes;
};

    The syslog destination clause directs the channel to the system log. Its argument is a syslog facility as described in the syslog man page. Known facilities are kern, user, mail, daemon, auth, syslog, lpr, news, uucp, cron, authpriv, ftp, local0, local1, local2, local3, local4, local5, local6 and local7, however not all facilities are supported on all operating systems. How syslog will handle messages sent to this facility is described in the syslog.conf man page. If you have a system which uses a very old version of syslog that only uses two arguments to the openlog() function, then this clause is silently ignored.

    The severity clause works like syslog's "priorities", except that they can also be used if you are writing straight to a file rather than using syslog. Messages which are not at least of the severity level given will not be selected for the channel; messages of higher severity levels will be accepted.

    If you are using syslog, then the syslog.conf priorities will also determine what eventually passes through. For example, defining a channel facility and severity as daemon and debug but only logging daemon.warning via syslog.conf will cause messages of severity info and notice to be dropped. If the situation were reversed, with named writing messages of only warning or higher, then syslogd would print all messages it received from the channel.

    The stderr destination clause directs the channel to the server's standard error stream. This is intended for use when the server is running as a foreground process, for example when debugging a configuration.

    The server can supply extensive debugging information when it is in debugging mode. If the server's global debug level is greater than zero, then debugging mode will be active. The global debug level is set either by starting the named server with the -d flag followed by a positive integer, or by running rndc trace. The global debug level can be set to zero, and debugging mode turned off, by running rndc notrace. All debugging messages in the server have a debug level, and higher debug levels give more detailed output. Channels that specify a specific debug severity, for example: 

    channel specific_debug_level {
    file "foo";
    severity debug 3;
};

    will get debugging output of level 3 or less any time the server is in debugging mode, regardless of the global debugging level. Channels with dynamic severity use the server's global debug level to determine what messages to print.

    If print-time has been turned on, then the date and time will be logged. print-time may be specified for a syslog channel, but is usually pointless since syslog also logs the date and time. If print-category is requested, then the category of the message will be logged as well. Finally, if print-severity is on, then the severity level of the message will be logged. The print- options may be used in any combination, and will always be printed in the following order: time, category, severity. Here is an example where all three print- options are on:

    28-Feb-2000 15:05:32.863 general: notice: running

    There are four predefined channels that are used for named's default logging as follows. How they are used is described in the section called “The category Phrase”. 

    channel default_syslog {
    syslog daemon;                      // send to syslog's daemon
                                        // facility
    severity info;                      // only send priority info
                                        // and higher
};

channel default_debug {
    file "named.run";                   // write to named.run in
                                        // the working directory
                                        // Note: stderr is used instead
                                        // of "named.run"
                                        // if the server is started
                                        // with the '-f' option.
    severity dynamic;                   // log at the server's
                                        // current debug level
};

channel default_stderr {
    stderr;                             // writes to stderr
    severity info;                      // only send priority info
                                        // and higher
};

channel null {
   null;                                // toss anything sent to
                                        // this channel
};

    The default_debug channel has the special property that it only produces output when the server's debug level is nonzero. It normally writes to a file called named.run in the server's working directory.

    For security reasons, when the "-u" command line option is used, the named.run file is created only after named has changed to the new UID, and any debug output generated while named is starting up and still running as root is discarded. If you need to capture this output, you must run the server with the "-g" option and redirect standard error to a file.

    Once a channel is defined, it cannot be redefined. Thus you cannot alter the built-in channels directly, but you can modify the default logging by pointing categories at channels you have defined.

    The category Phrase

    There are many categories, so you can send the logs you want to see wherever you want, without seeing logs you don't want. If you don't specify a list of channels for a category, then log messages in that category will be sent to the default category instead. If you don't specify a default category, the following "default default" is used: 

    category default { default_syslog; default_debug; };

    As an example, let's say you want to log security events to a file, but you also want keep the default logging behavior. You'd specify the following: 

    channel my_security_channel {
    file "my_security_file";
    severity info;
};
category security {
    my_security_channel;
    default_syslog;
    default_debug;
};

    To discard all messages in a category, specify the null channel: 

    category xfer-out { null; };
category notify { null; };

    Following are the available categories and brief descriptions of the types of log information they contain. More categories may be added in future BIND releases.

    default

    The default category defines the logging options for those categories where no specific configuration has been defined.

    general

    The catch-all. Many things still aren't classified into categories, and they all end up here.

    database

    Messages relating to the databases used internally by the name server to store zone and cache data.

    security

    Approval and denial of requests.

    config

    Configuration file parsing and processing.

    resolver

    DNS resolution, such as the recursive lookups performed on behalf of clients by a caching name server.

    xfer-in

    Zone transfers the server is receiving.

    xfer-out

    Zone transfers the server is sending.

    notify

    The NOTIFY protocol.

    client

    Processing of client requests.

    unmatched

    Messages that named was unable to determine the class of or for which there was no matching view. A one line summary is also logged to the client category. This category is best sent to a file or stderr, by default it is sent to the null channel.

    network

    Network operations.

    update

    Dynamic updates.

    update-security

    Approval and denial of update requests.

    queries

    Specify where queries should be logged to.

    At startup, specifying the category queries will also enable query logging unless querylog option has been specified.

    The query log entry reports the client's IP address and port number, and the query name, class and type. It also reports whether the Recursion Desired flag was set (+ if set, - if not set), if the query was signed (S), EDNS was in use (E), if DO (DNSSEC Ok) was set (D), or if CD (Checking Disabled) was set (C).

    client 127.0.0.1#62536: query: www.example.com IN AAAA +SE

    client ::1#62537: query: www.example.net IN AAAA -SE

    query-errors

    Information about queries that resulted in some failure.

    dispatch

    Dispatching of incoming packets to the server modules where they are to be processed.

    dnssec

    DNSSEC and TSIG protocol processing.

    lame-servers

    Lame servers. These are misconfigurations in remote servers, discovered by BIND 9 when trying to query those servers during resolution.

    delegation-only

    Delegation only. Logs queries that have been forced to NXDOMAIN as the result of a delegation-only zone or a delegation-only in a hint or stub zone declaration.

    edns-disabled

    Log queries that have been forced to use plain DNS due to timeouts. This is often due to the remote servers not being RFC 1034 compliant (not always returning FORMERR or similar to EDNS queries and other extensions to the DNS when they are not understood). In other words, this is targeted at servers that fail to respond to DNS queries that they don't understand.

    Note: the log message can also be due to packet loss. Before reporting servers for non-RFC 1034 compliance they should be re-tested to determine the nature of the non-compliance. This testing should prevent or reduce the number of false-positive reports.

    Note: eventually named will have to stop treating such timeouts as due to RFC 1034 non compliance and start treating it as plain packet loss. Falsely classifying packet loss as due to RFC 1034 non compliance impacts on DNSSEC validation which requires EDNS for the DNSSEC records to be returned.

    The query-errors Category

    The query-errors category is specifically intended for debugging purposes: To identify why and how specific queries result in responses which indicate an error. Messages of this category are therefore only logged with debug levels.

    At the debug levels of 1 or higher, each response with the rcode of SERVFAIL is logged as follows:

    client 127.0.0.1#61502: query failed (SERVFAIL) for www.example.com/IN/AAAA at query.c:3880

    This means an error resulting in SERVFAIL was detected at line 3880 of source file query.c. Log messages of this level will particularly help identify the cause of SERVFAIL for an authoritative server.

    At the debug levels of 2 or higher, detailed context information of recursive resolutions that resulted in SERVFAIL is logged. The log message will look like as follows:

    fetch completed at resolver.c:2970 for www.example.com/A in 30.000183: timed out/success [domain:example.com,referral:2,restart:7,qrysent:8,timeout:5,lame:0,neterr:0,badresp:1,adberr:0,findfail:0,valfail:0]

    The first part before the colon shows that a recursive resolution for AAAA records of www.example.com completed in 30.000183 seconds and the final result that led to the SERVFAIL was determined at line 2970 of source file resolver.c.

    The following part shows the detected final result and the latest result of DNSSEC validation. The latter is always success when no validation attempt is made. In this example, this query resulted in SERVFAIL probably because all name servers are down or unreachable, leading to a timeout in 30 seconds. DNSSEC validation was probably not attempted.

    The last part enclosed in square brackets shows statistics information collected for this particular resolution attempt. The domain field shows the deepest zone that the resolver reached; it is the zone where the error was finally detected. The meaning of the other fields is summarized in the following table.

    referral

    The number of referrals the resolver received throughout the resolution process. In the above example this is 2, which are most likely com and example.com.

    restart

    The number of cycles that the resolver tried remote servers at the domain zone. In each cycle the resolver sends one query (possibly resending it, depending on the response) to each known name server of the domain zone.

    qrysent

    The number of queries the resolver sent at the domain zone.

    timeout

    The number of timeouts since the resolver received the last response.

    lame

    The number of lame servers the resolver detected at the domain zone. A server is detected to be lame either by an invalid response or as a result of lookup in BIND9's address database (ADB), where lame servers are cached.

    neterr

    The number of erroneous results that the resolver encountered in sending queries at the domain zone. One common case is the remote server is unreachable and the resolver receives an ICMP unreachable error message.

    badresp

    The number of unexpected responses (other than lame) to queries sent by the resolver at the domain zone.

    adberr

    Failures in finding remote server addresses of the domain zone in the ADB. One common case of this is that the remote server's name does not have any address records.

    findfail

    Failures of resolving remote server addresses. This is a total number of failures throughout the resolution process.

    valfail

    Failures of DNSSEC validation. Validation failures are counted throughout the resolution process (not limited to the domain zone), but should only happen in domain.

    At the debug levels of 3 or higher, the same messages as those at the debug 1 level are logged for other errors than SERVFAIL. Note that negative responses such as NXDOMAIN are not regarded as errors here.

    At the debug levels of 4 or higher, the same messages as those at the debug 2 level are logged for other errors than SERVFAIL. Unlike the above case of level 3, messages are logged for negative responses. This is because any unexpected results can be difficult to debug in the recursion case.

    lwres Statement Grammar

    This is the grammar of the lwres statement in the named.conf file: 

    lwres {
    [ listen-on { ip_addr [port ip_port] ; [ ip_addr [port ip_port] ; ... ] }; ]
    [ view view_name; ]
    [ search { domain_name ; [ domain_name ; ... ] }; ]
    [ ndots number; ]
};

    lwres Statement Definition and Usage

    The lwres statement configures the name server to also act as a lightweight resolver server. (See the section called “Running a Resolver Daemon”.) There may be multiple lwres statements configuring lightweight resolver servers with different properties.

    The listen-on statement specifies a list of addresses (and ports) that this instance of a lightweight resolver daemon should accept requests on. If no port is specified, port 921 is used. If this statement is omitted, requests will be accepted on 127.0.0.1, port 921.

    The view statement binds this instance of a lightweight resolver daemon to a view in the DNS namespace, so that the response will be constructed in the same manner as a normal DNS query matching this view. If this statement is omitted, the default view is used, and if there is no default view, an error is triggered.

    The search statement is equivalent to the search statement in /etc/resolv.conf. It provides a list of domains which are appended to relative names in queries.

    The ndots statement is equivalent to the ndots statement in /etc/resolv.conf. It indicates the minimum number of dots in a relative domain name that should result in an exact match lookup before search path elements are appended.

    masters Statement Grammar

    masters name [port ip_port] { ( masters_list | ip_addr [port ip_port] [key key] ) ; [...] };

    masters Statement Definition and Usage

    masters lists allow for a common set of masters to be easily used by multiple stub and slave zones.

    options Statement Definition and Usage

    The options statement sets up global options to be used by BIND. This statement may appear only once in a configuration file. If there is no options statement, an options block with each option set to its default will be used.

    directory

    The working directory of the server. Any non-absolute pathnames in the configuration file will be taken as relative to this directory. The default location for most server output files (e.g. named.run) is this directory. If a directory is not specified, the working directory defaults to `.', the directory from which the server was started. The directory specified should be an absolute path.

    key-directory

    When performing dynamic update of secure zones, the directory where the public and private DNSSEC key files should be found, if different than the current working directory. The directory specified must be an absolute path. (Note that this option has no effect on the paths for files containing non-DNSSEC keys such as the rndc.key.

    named-xfer

    This option is obsolete. It was used in BIND 8 to specify the pathname to the named-xfer program. In BIND 9, no separate named-xfer program is needed; its functionality is built into the name server.

    tkey-gssapi-credential

    The security credential with which the server should authenticate keys requested by the GSS-TSIG protocol. Currently only Kerberos 5 authentication is available and the credential is a Kerberos principal which the server can acquire through the default system key file, normally /etc/krb5.keytab. Normally this principal is of the form "DNS/server.domain". To use GSS-TSIG, tkey-domain must also be set.

    tkey-domain

    The domain appended to the names of all shared keys generated with TKEY. When a client requests a TKEY exchange, it may or may not specify the desired name for the key. If present, the name of the shared key will be client specified part + tkey-domain. Otherwise, the name of the shared key will be random hex digits + tkey-domain. In most cases, the domainname should be the server's domain name, or an otherwise non-existent subdomain like "_tkey.domainname". If you are using GSS-TSIG, this variable must be defined.

    tkey-dhkey

    The Diffie-Hellman key used by the server to generate shared keys with clients using the Diffie-Hellman mode of TKEY. The server must be able to load the public and private keys from files in the working directory. In most cases, the keyname should be the server's host name.

    cache-file

    This is for testing only. Do not use.

    dump-file

    The pathname of the file the server dumps the database to when instructed to do so with rndc dumpdb. If not specified, the default is named_dump.db.

    memstatistics-file

    The pathname of the file the server writes memory usage statistics to on exit. If not specified, the default is named.memstats.

    pid-file

    The pathname of the file the server writes its process ID in. If not specified, the default is /var/run/named/named.pid. The PID file is used by programs that want to send signals to the running name server. Specifying pid-file none disables the use of a PID file — no file will be written and any existing one will be removed. Note that none is a keyword, not a filename, and therefore is not enclosed in double quotes.

    recursing-file

    The pathname of the file the server dumps the queries that are currently recursing when instructed to do so with rndc recursing. If not specified, the default is named.recursing.

    statistics-file

    The pathname of the file the server appends statistics to when instructed to do so using rndc stats. If not specified, the default is named.stats in the server's current directory. The format of the file is described in the section called “The Statistics File”.

    port

    The UDP/TCP port number the server uses for receiving and sending DNS protocol traffic. The default is 53. This option is mainly intended for server testing; a server using a port other than 53 will not be able to communicate with the global DNS.

    random-device

    The source of entropy to be used by the server. Entropy is primarily needed for DNSSEC operations, such as TKEY transactions and dynamic update of signed zones. This options specifies the device (or file) from which to read entropy. If this is a file, operations requiring entropy will fail when the file has been exhausted. If not specified, the default value is /dev/random (or equivalent) when present, and none otherwise. The random-device option takes effect during the initial configuration load at server startup time and is ignored on subsequent reloads.

    preferred-glue

    If specified, the listed type (A or AAAA) will be emitted before other glue in the additional section of a query response. The default is not to prefer any type (NONE).

    root-delegation-only

    Turn on enforcement of delegation-only in TLDs (top level domains) and root zones with an optional exclude list.

    DS queries are expected to be made to and be answered by delegation only zones. Such queries and responses are treated as a exception to delegation-only processing and are not converted to NXDOMAIN responses provided a CNAME is not discovered at the query name.

    If a delegation only zone server also serves a child zone it is not always possible to determine whether a answer comes from the delegation only zone or the child zone. SOA NS and DNSKEY records are apex only records and a matching response that contains these records or DS is treated as coming from a child zone. RRSIG records are also examined to see if they are signed by a child zone or not. The authority section is also examined to see if there is evidence that the answer is from the child zone. Answers that are determined to be from a child zone are not converted to NXDOMAIN responses. Despite all these checks there is still a possibility of false negatives when a child zone is being served.

    Similarly false positives can arise from empty nodes (no records at the name) in the delegation only zone when the query type is not ANY.

    Note some TLDs are not delegation only (e.g. "DE", "LV", "US" and "MUSEUM"). This list is not exhaustive. 

    options {
        root-delegation-only exclude { "de"; "lv"; "us"; "museum"; };
};
    disable-algorithms

    Disable the specified DNSSEC algorithms at and below the specified name. Multiple disable-algorithms statements are allowed. Only the most specific will be applied.

    dnssec-lookaside

    When set, dnssec-lookaside provides the validator with an alternate method to validate DNSKEY records at the top of a zone. When a DNSKEY is at or below a domain specified by the deepest dnssec-lookaside, and the normal DNSSEC validation has left the key untrusted, the trust-anchor will be append to the key name and a DLV record will be looked up to see if it can validate the key. If the DLV record validates a DNSKEY (similarly to the way a DS record does) the DNSKEY RRset is deemed to be trusted.

    dnssec-must-be-secure

    Specify hierarchies which must be or may not be secure (signed and validated). If yes, then named will only accept answers if they are secure. If no, then normal DNSSEC validation applies allowing for insecure answers to be accepted. The specified domain must be under a trusted-key or dnssec-lookaside must be active.

    Boolean Options

    auth-nxdomain

    If yes, then the AA bit is always set on NXDOMAIN responses, even if the server is not actually authoritative. The default is no; this is a change from BIND 8. If you are using very old DNS software, you may need to set it to yes.

    deallocate-on-exit

    This option was used in BIND 8 to enable checking for memory leaks on exit. BIND 9 ignores the option and always performs the checks.

    memstatistics

    Write memory statistics to the file specified by memstatistics-file at exit. The default is no unless '-m record' is specified on the command line in which case it is yes.

    dialup

    If yes, then the server treats all zones as if they are doing zone transfers across a dial-on-demand dialup link, which can be brought up by traffic originating from this server. This has different effects according to zone type and concentrates the zone maintenance so that it all happens in a short interval, once every heartbeat-interval and hopefully during the one call. It also suppresses some of the normal zone maintenance traffic. The default is no.

    The dialup option may also be specified in the view and zone statements, in which case it overrides the global dialup option.

    If the zone is a master zone, then the server will send out a NOTIFY request to all the slaves (default). This should trigger the zone serial number check in the slave (providing it supports NOTIFY) allowing the slave to verify the zone while the connection is active. The set of servers to which NOTIFY is sent can be controlled by notify and also-notify.

    If the zone is a slave or stub zone, then the server will suppress the regular "zone up to date" (refresh) queries and only perform them when the heartbeat-interval expires in addition to sending NOTIFY requests.

    Finer control can be achieved by using notify which only sends NOTIFY messages, notify-passive which sends NOTIFY messages and suppresses the normal refresh queries, refresh which suppresses normal refresh processing and sends refresh queries when the heartbeat-interval expires, and passive which just disables normal refresh processing.

    dialup mode

    normal refresh

    heart-beat refresh

    heart-beat notify

    no (default)

    yes

    no

    no

    no

    notify-passive

    no

    no

    yes

    Note that normal NOTIFY processing is not affected by dialup.

    fake-iquery

    In BIND 8, this option enabled simulating the obsolete DNS query type IQUERY. BIND 9 never does IQUERY simulation.

    fetch-glue

    This option is obsolete. In BIND 8, fetch-glue yes caused the server to attempt to fetch glue resource records it didn't have when constructing the additional data section of a response. This is now considered a bad idea and BIND 9 never does it.

    flush-zones-on-shutdown

    When the nameserver exits due receiving SIGTERM, flush or do not flush any pending zone writes. The default is flush-zones-on-shutdown no.

    has-old-clients

    This option was incorrectly implemented in BIND 8, and is ignored by BIND 9. To achieve the intended effect of has-old-clients yes, specify the two separate options auth-nxdomain yes and rfc2308-type1 no instead.

    host-statistics

    In BIND 8, this enables keeping of statistics for every host that the name server interacts with. Not implemented in BIND 9.

    maintain-ixfr-base

    This option is obsolete. It was used in BIND 8 to determine whether a transaction log was kept for Incremental Zone Transfer. BIND 9 maintains a transaction log whenever possible. If you need to disable outgoing incremental zone transfers, use provide-ixfr no.

    minimal-responses

    If yes, then when generating responses the server will only add records to the authority and additional data sections when they are required (e.g. delegations, negative responses). This may improve the performance of the server. The default is no.

    multiple-cnames

    This option was used in BIND 8 to allow a domain name to have multiple CNAME records in violation of the DNS standards. BIND 9.2 onwards always strictly enforces the CNAME rules both in master files and dynamic updates.

    notify

    If yes (the default), DNS NOTIFY messages are sent when a zone the server is authoritative for changes, see the section called “Notify”. The messages are sent to the servers listed in the zone's NS records (except the master server identified in the SOA MNAME field), and to any servers listed in the also-notify option.

    If master-only, notifies are only sent for master zones. If explicit, notifies are sent only to servers explicitly listed using also-notify. If no, no notifies are sent.

    The notify option may also be specified in the zone statement, in which case it overrides the options notify statement. It would only be necessary to turn off this option if it caused slaves to crash.

    notify-to-soa

    If yes do not check the nameservers in the NS RRset against the SOA MNAME. Normally a NOTIFY message is not sent to the SOA MNAME (SOA ORIGIN) as it is supposed to contain the name of the ultimate master. Sometimes, however, a slave is listed as the SOA MNAME in hidden master configurations and in that case you would want the ultimate master to still send NOTIFY messages to all the nameservers listed in the NS RRset.

    recursion

    If yes, and a DNS query requests recursion, then the server will attempt to do all the work required to answer the query. If recursion is off and the server does not already know the answer, it will return a referral response. The default is yes. Note that setting recursion no does not prevent clients from getting data from the server's cache; it only prevents new data from being cached as an effect of client queries. Caching may still occur as an effect the server's internal operation, such as NOTIFY address lookups. See also fetch-glue above.

    rfc2308-type1

    Setting this to yes will cause the server to send NS records along with the SOA record for negative answers. The default is no.

    Note

    Not yet implemented in BIND 9.

    use-id-pool

    This option is obsolete. BIND 9 always allocates query IDs from a pool.

    zone-statistics

    If yes, the server will collect statistical data on all zones (unless specifically turned off on a per-zone basis by specifying zone-statistics no in the zone statement). These statistics may be accessed using rndc stats, which will dump them to the file listed in the statistics-file. See also the section called “The Statistics File”.

    use-ixfr

    This option is obsolete. If you need to disable IXFR to a particular server or servers, see the information on the provide-ixfr option in the section called “server Statement Definition and Usage”. See also the section called “Incremental Zone Transfers (IXFR)”.

    provide-ixfr

    See the description of provide-ixfr in the section called “server Statement Definition and Usage”.

    request-ixfr

    See the description of request-ixfr in the section called “server Statement Definition and Usage”.

    treat-cr-as-space

    This option was used in BIND 8 to make the server treat carriage return ("\r") characters the same way as a space or tab character, to facilitate loading of zone files on a UNIX system that were generated on an NT or DOS machine. In BIND 9, both UNIX "\n" and NT/DOS "\r\n" newlines are always accepted, and the option is ignored.

    additional-from-auth, additional-from-cache

    These options control the behavior of an authoritative server when answering queries which have additional data, or when following CNAME and DNAME chains.

    When both of these options are set to yes (the default) and a query is being answered from authoritative data (a zone configured into the server), the additional data section of the reply will be filled in using data from other authoritative zones and from the cache. In some situations this is undesirable, such as when there is concern over the correctness of the cache, or in servers where slave zones may be added and modified by untrusted third parties. Also, avoiding the search for this additional data will speed up server operations at the possible expense of additional queries to resolve what would otherwise be provided in the additional section.

    For example, if a query asks for an MX record for host foo.example.com, and the record found is "MX 10 mail.example.net", normally the address records (A and AAAA) for mail.example.net will be provided as well, if known, even though they are not in the example.com zone. Setting these options to no disables this behavior and makes the server only search for additional data in the zone it answers from.

    These options are intended for use in authoritative-only servers, or in authoritative-only views. Attempts to set them to no without also specifying recursion no will cause the server to ignore the options and log a warning message.

    Specifying additional-from-cache no actually disables the use of the cache not only for additional data lookups but also when looking up the answer. This is usually the desired behavior in an authoritative-only server where the correctness of the cached data is an issue.

    When a name server is non-recursively queried for a name that is not below the apex of any served zone, it normally answers with an "upwards referral" to the root servers or the servers of some other known parent of the query name. Since the data in an upwards referral comes from the cache, the server will not be able to provide upwards referrals when additional-from-cache no has been specified. Instead, it will respond to such queries with REFUSED. This should not cause any problems since upwards referrals are not required for the resolution process.

    match-mapped-addresses

    If yes, then an IPv4-mapped IPv6 address will match any address match list entries that match the corresponding IPv4 address.

    This option was introduced to work around a kernel quirk in some operating systems that causes IPv4 TCP connections, such as zone transfers, to be accepted on an IPv6 socket using mapped addresses. This caused address match lists designed for IPv4 to fail to match. However, named now solves this problem internally. The use of this option is discouraged.

    ixfr-from-differences

    When yes and the server loads a new version of a master zone from its zone file or receives a new version of a slave file by a non-incremental zone transfer, it will compare the new version to the previous one and calculate a set of differences. The differences are then logged in the zone's journal file such that the changes can be transmitted to downstream slaves as an incremental zone transfer.

    By allowing incremental zone transfers to be used for non-dynamic zones, this option saves bandwidth at the expense of increased CPU and memory consumption at the master. In particular, if the new version of a zone is completely different from the previous one, the set of differences will be of a size comparable to the combined size of the old and new zone version, and the server will need to temporarily allocate memory to hold this complete difference set.

    ixfr-from-differences also accepts master and slave at the view and options levels which causes ixfr-from-differences to be enabled for all master or slave zones respectively. It is off by default.

    multi-master

    This should be set when you have multiple masters for a zone and the addresses refer to different machines. If yes, named will not log when the serial number on the master is less than what named currently has. The default is no.

    dnssec-enable

    Enable DNSSEC support in named. Unless set to yes, named behaves as if it does not support DNSSEC. The default is yes.

    dnssec-validation

    Enable DNSSEC validation in named. Note dnssec-enable also needs to be set to yes to be effective. The default is yes.

    dnssec-accept-expired

    Accept expired signatures when verifying DNSSEC signatures. The default is no. Setting this option to "yes" leaves named vulnerable to replay attacks.

    querylog

    Specify whether query logging should be started when named starts. If querylog is not specified, then the query logging is determined by the presence of the logging category queries.

    check-names

    This option is used to restrict the character set and syntax of certain domain names in master files and/or DNS responses received from the network. The default varies according to usage area. For master zones the default is fail. For slave zones the default is warn. For answers received from the network (response) the default is ignore.

    The rules for legal hostnames and mail domains are derived from RFC 952 and RFC 821 as modified by RFC 1123.

    check-names applies to the owner names of A, AAAA and MX records. It also applies to the domain names in the RDATA of NS, SOA, MX, and SRV records. It also applies to the RDATA of PTR records where the owner name indicated that it is a reverse lookup of a hostname (the owner name ends in IN-ADDR.ARPA, IP6.ARPA, or IP6.INT).

    check-mx

    Check whether the MX record appears to refer to a IP address. The default is to warn. Other possible values are fail and ignore.

    check-wildcard

    This option is used to check for non-terminal wildcards. The use of non-terminal wildcards is almost always as a result of a failure to understand the wildcard matching algorithm (RFC 1034). This option affects master zones. The default (yes) is to check for non-terminal wildcards and issue a warning.

    check-integrity

    Perform post load zone integrity checks on master zones. This checks that MX and SRV records refer to address (A or AAAA) records and that glue address records exist for delegated zones. For MX and SRV records only in-zone hostnames are checked (for out-of-zone hostnames use named-checkzone). For NS records only names below top of zone are checked (for out-of-zone names and glue consistency checks use named-checkzone). The default is yes.

    check-mx-cname

    If check-integrity is set then fail, warn or ignore MX records that refer to CNAMES. The default is to warn.

    check-srv-cname

    If check-integrity is set then fail, warn or ignore SRV records that refer to CNAMES. The default is to warn.

    check-sibling

    When performing integrity checks, also check that sibling glue exists. The default is yes.

    zero-no-soa-ttl

    When returning authoritative negative responses to SOA queries set the TTL of the SOA record returned in the authority section to zero. The default is yes.

    zero-no-soa-ttl-cache

    When caching a negative response to a SOA query set the TTL to zero. The default is no.

    update-check-ksk

    When regenerating the RRSIGs following a UPDATE request to a secure zone, check the KSK flag on the DNSKEY RR to determine if this key should be used to generate the RRSIG. This flag is ignored if there are not DNSKEY RRs both with and without a KSK. The default is yes.

    try-tcp-refresh

    Try to refresh the zone using TCP if UDP queries fail. For BIND 8 compatibility, the default is yes.

    Forwarding

    The forwarding facility can be used to create a large site-wide cache on a few servers, reducing traffic over links to external name servers. It can also be used to allow queries by servers that do not have direct access to the Internet, but wish to look up exterior names anyway. Forwarding occurs only on those queries for which the server is not authoritative and does not have the answer in its cache.

    forward

    This option is only meaningful if the forwarders list is not empty. A value of first, the default, causes the server to query the forwarders first — and if that doesn't answer the question, the server will then look for the answer itself. If only is specified, the server will only query the forwarders.

    forwarders

    Specifies the IP addresses to be used for forwarding. The default is the empty list (no forwarding).

    Forwarding can also be configured on a per-domain basis, allowing for the global forwarding options to be overridden in a variety of ways. You can set particular domains to use different forwarders, or have a different forward only/first behavior, or not forward at all, see the section called “zone Statement Grammar”.

    Dual-stack Servers

    Dual-stack servers are used as servers of last resort to work around problems in reachability due the lack of support for either IPv4 or IPv6 on the host machine.

    dual-stack-servers

    Specifies host names or addresses of machines with access to both IPv4 and IPv6 transports. If a hostname is used, the server must be able to resolve the name using only the transport it has. If the machine is dual stacked, then the dual-stack-servers have no effect unless access to a transport has been disabled on the command line (e.g. named -4).

    Access Control

    Access to the server can be restricted based on the IP address of the requesting system. See the section called “Address Match Lists” for details on how to specify IP address lists.

    allow-notify

    Specifies which hosts are allowed to notify this server, a slave, of zone changes in addition to the zone masters. allow-notify may also be specified in the zone statement, in which case it overrides the options allow-notify statement. It is only meaningful for a slave zone. If not specified, the default is to process notify messages only from a zone's master.

    allow-query

    Specifies which hosts are allowed to ask ordinary DNS questions. allow-query may also be specified in the zone statement, in which case it overrides the options allow-query statement. If not specified, the default is to allow queries from all hosts.

    Note

    allow-query-cache is now used to specify access to the cache.

    allow-query-on

    Specifies which local addresses can accept ordinary DNS questions. This makes it possible, for instance, to allow queries on internal-facing interfaces but disallow them on external-facing ones, without necessarily knowing the internal network's addresses.

    allow-query-on may also be specified in the zone statement, in which case it overrides the options allow-query-on statement.

    If not specified, the default is to allow queries on all addresses.

    Note

    allow-query-cache is used to specify access to the cache.

    allow-query-cache

    Specifies which hosts are allowed to get answers from the cache. If allow-query-cache is not set then allow-recursion is used if set, otherwise allow-query is used if set unless recursion no; is set in which case none; is used, otherwise the default (localnets; localhost;) is used.

    allow-query-cache-on

    Specifies which local addresses can give answers from the cache. If not specified, the default is to allow cache queries on any address, localnets and localhost.

    allow-recursion

    Specifies which hosts are allowed to make recursive queries through this server. If allow-recursion is not set then allow-query-cache is used if set, otherwise allow-query is used if set, otherwise the default (localnets; localhost;) is used.

    allow-recursion-on

    Specifies which local addresses can accept recursive queries. If not specified, the default is to allow recursive queries on all addresses.

    allow-update

    Specifies which hosts are allowed to submit Dynamic DNS updates for master zones. The default is to deny updates from all hosts. Note that allowing updates based on the requestor's IP address is insecure; see the section called “Dynamic Update Security” for details.

    allow-update-forwarding

    Specifies which hosts are allowed to submit Dynamic DNS updates to slave zones to be forwarded to the master. The default is { none; }, which means that no update forwarding will be performed. To enable update forwarding, specify allow-update-forwarding { any; };. Specifying values other than { none; } or { any; } is usually counterproductive, since the responsibility for update access control should rest with the master server, not the slaves.

    Note that enabling the update forwarding feature on a slave server may expose master servers relying on insecure IP address based access control to attacks; see the section called “Dynamic Update Security” for more details.

    allow-v6-synthesis

    This option was introduced for the smooth transition from AAAA to A6 and from "nibble labels" to binary labels. However, since both A6 and binary labels were then deprecated, this option was also deprecated. It is now ignored with some warning messages.

    allow-transfer

    Specifies which hosts are allowed to receive zone transfers from the server. allow-transfer may also be specified in the zone statement, in which case it overrides the options allow-transfer statement. If not specified, the default is to allow transfers to all hosts.

    blackhole

    Specifies a list of addresses that the server will not accept queries from or use to resolve a query. Queries from these addresses will not be responded to. The default is none.

    Interfaces

    The interfaces and ports that the server will answer queries from may be specified using the listen-on option. listen-on takes an optional port and an address_match_list. The server will listen on all interfaces allowed by the address match list. If a port is not specified, port 53 will be used.

    Multiple listen-on statements are allowed. For example, 

    listen-on { 5.6.7.8; };
listen-on port 1234 { !1.2.3.4; 1.2/16; };

    will enable the name server on port 53 for the IP address 5.6.7.8, and on port 1234 of an address on the machine in net 1.2 that is not 1.2.3.4.

    If no listen-on is specified, the server will listen on port 53 on all IPv4 interfaces.

    The listen-on-v6 option is used to specify the interfaces and the ports on which the server will listen for incoming queries sent using IPv6.

    When 

    { any; }

    is specified as the address_match_list for the listen-on-v6 option, the server does not bind a separate socket to each IPv6 interface address as it does for IPv4 if the operating system has enough API support for IPv6 (specifically if it conforms to RFC 3493 and RFC 3542). Instead, it listens on the IPv6 wildcard address. If the system only has incomplete API support for IPv6, however, the behavior is the same as that for IPv4.

    A list of particular IPv6 addresses can also be specified, in which case the server listens on a separate socket for each specified address, regardless of whether the desired API is supported by the system.

    Multiple listen-on-v6 options can be used. For example, 

    listen-on-v6 { any; };
listen-on-v6 port 1234 { !2001:db8::/32; any; };

    will enable the name server on port 53 for any IPv6 addresses (with a single wildcard socket), and on port 1234 of IPv6 addresses that is not in the prefix 2001:db8::/32 (with separate sockets for each matched address.)

    To make the server not listen on any IPv6 address, use 

    listen-on-v6 { none; };

    If no listen-on-v6 option is specified, the server will not listen on any IPv6 address unless -6 is specified when named is invoked. If -6 is specified then named will listen on port 53 on all IPv6 interfaces by default.

    Query Address

    If the server doesn't know the answer to a question, it will query other name servers. query-source specifies the address and port used for such queries. For queries sent over IPv6, there is a separate query-source-v6 option. If address is * (asterisk) or is omitted, a wildcard IP address (INADDR_ANY) will be used.

    If port is * or is omitted, a random port number from a pre-configured range is picked up and will be used for each query. The port range(s) is that specified in the use-v4-udp-ports (for IPv4) and use-v6-udp-ports (for IPv6) options, excluding the ranges specified in the avoid-v4-udp-ports and avoid-v6-udp-ports options, respectively.

    The defaults of the query-source and query-source-v6 options are: 

    query-source address * port *;
query-source-v6 address * port *;

    If use-v4-udp-ports or use-v6-udp-ports is unspecified, named will check if the operating system provides a programming interface to retrieve the system's default range for ephemeral ports. If such an interface is available, named will use the corresponding system default range; otherwise, it will use its own defaults: 

    use-v4-udp-ports { range 1024 65535; };
use-v6-udp-ports { range 1024 65535; };

    Note: make sure the ranges be sufficiently large for security. A desirable size depends on various parameters, but we generally recommend it contain at least 16384 ports (14 bits of entropy). Note also that the system's default range when used may be too small for this purpose, and that the range may even be changed while named is running; the new range will automatically be applied when named is reloaded. It is encouraged to configure use-v4-udp-ports and use-v6-udp-ports explicitly so that the ranges are sufficiently large and are reasonably independent from the ranges used by other applications.

    Note: the operational configuration where named runs may prohibit the use of some ports. For example, UNIX systems will not allow named running without a root privilege to use ports less than 1024. If such ports are included in the specified (or detected) set of query ports, the corresponding query attempts will fail, resulting in resolution failures or delay. It is therefore important to configure the set of ports that can be safely used in the expected operational environment.

    The defaults of the avoid-v4-udp-ports and avoid-v6-udp-ports options are: 

    avoid-v4-udp-ports {};
avoid-v6-udp-ports {};

    Note: BIND 9.5.0 introduced the use-queryport-pool option to support a pool of such random ports, but this option is now obsolete because reusing the same ports in the pool may not be sufficiently secure. For the same reason, it is generally strongly discouraged to specify a particular port for the query-source or query-source-v6 options; it implicitly disables the use of randomized port numbers.

    use-queryport-pool

    This option is obsolete.

    queryport-pool-ports

    This option is obsolete.

    queryport-pool-updateinterval

    This option is obsolete.

    Note

    The address specified in the query-source option is used for both UDP and TCP queries, but the port applies only to UDP queries. TCP queries always use a random unprivileged port.

    Note

    Solaris 2.5.1 and earlier does not support setting the source address for TCP sockets.

    Note

    See also transfer-source and notify-source.

    Zone Transfers

    BIND has mechanisms in place to facilitate zone transfers and set limits on the amount of load that transfers place on the system. The following options apply to zone transfers.

    also-notify

    Defines a global list of IP addresses of name servers that are also sent NOTIFY messages whenever a fresh copy of the zone is loaded, in addition to the servers listed in the zone's NS records. This helps to ensure that copies of the zones will quickly converge on stealth servers. Optionally, a port may be specified with each also-notify address to send the notify messages to a port other than the default of 53. If an also-notify list is given in a zone statement, it will override the options also-notify statement. When a zone notify statement is set to no, the IP addresses in the global also-notify list will not be sent NOTIFY messages for that zone. The default is the empty list (no global notification list).

    max-transfer-time-in

    Inbound zone transfers running longer than this many minutes will be terminated. The default is 120 minutes (2 hours). The maximum value is 28 days (40320 minutes).

    max-transfer-idle-in

    Inbound zone transfers making no progress in this many minutes will be terminated. The default is 60 minutes (1 hour). The maximum value is 28 days (40320 minutes).

    max-transfer-time-out

    Outbound zone transfers running longer than this many minutes will be terminated. The default is 120 minutes (2 hours). The maximum value is 28 days (40320 minutes).

    max-transfer-idle-out

    Outbound zone transfers making no progress in this many minutes will be terminated. The default is 60 minutes (1 hour). The maximum value is 28 days (40320 minutes).

    serial-query-rate

    Slave servers will periodically query master servers to find out if zone serial numbers have changed. Each such query uses a minute amount of the slave server's network bandwidth. To limit the amount of bandwidth used, BIND 9 limits the rate at which queries are sent. The value of the serial-query-rate option, an integer, is the maximum number of queries sent per second. The default is 20.

    In addition to controlling the rate SOA refresh queries are issued at serial-query-rate also controls the rate at which NOTIFY messages are sent from both master and slave zones.

    serial-queries

    In BIND 8, the serial-queries option set the maximum number of concurrent serial number queries allowed to be outstanding at any given time. BIND 9 does not limit the number of outstanding serial queries and ignores the serial-queries option. Instead, it limits the rate at which the queries are sent as defined using the serial-query-rate option.

    transfer-format

    Zone transfers can be sent using two different formats, one-answer and many-answers. The transfer-format option is used on the master server to determine which format it sends. one-answer uses one DNS message per resource record transferred. many-answers packs as many resource records as possible into a message. many-answers is more efficient, but is only supported by relatively new slave servers, such as BIND 9, BIND 8.x and BIND 4.9.5 onwards. The many-answers format is also supported by recent Microsoft Windows nameservers. The default is many-answers. transfer-format may be overridden on a per-server basis by using the server statement.

    transfers-in

    The maximum number of inbound zone transfers that can be running concurrently. The default value is 10. Increasing transfers-in may speed up the convergence of slave zones, but it also may increase the load on the local system.

    transfers-out

    The maximum number of outbound zone transfers that can be running concurrently. Zone transfer requests in excess of the limit will be refused. The default value is 10.

    transfers-per-ns

    The maximum number of inbound zone transfers that can be concurrently transferring from a given remote name server. The default value is 2. Increasing transfers-per-ns may speed up the convergence of slave zones, but it also may increase the load on the remote name server. transfers-per-ns may be overridden on a per-server basis by using the transfers phrase of the server statement.

    transfer-source

    transfer-source determines which local address will be bound to IPv4 TCP connections used to fetch zones transferred inbound by the server. It also determines the source IPv4 address, and optionally the UDP port, used for the refresh queries and forwarded dynamic updates. If not set, it defaults to a system controlled value which will usually be the address of the interface "closest to" the remote end. This address must appear in the remote end's allow-transfer option for the zone being transferred, if one is specified. This statement sets the transfer-source for all zones, but can be overridden on a per-view or per-zone basis by including a transfer-source statement within the view or zone block in the configuration file.

    Note

    Solaris 2.5.1 and earlier does not support setting the source address for TCP sockets.

    transfer-source-v6

    The same as transfer-source, except zone transfers are performed using IPv6.

    alt-transfer-source

    An alternate transfer source if the one listed in transfer-source fails and use-alt-transfer-source is set.

    Note

    If you do not wish the alternate transfer source to be used, you should set use-alt-transfer-source appropriately and you should not depend upon getting an answer back to the first refresh query.
    alt-transfer-source-v6

    An alternate transfer source if the one listed in transfer-source-v6 fails and use-alt-transfer-source is set.

    use-alt-transfer-source

    Use the alternate transfer sources or not. If views are specified this defaults to no otherwise it defaults to yes (for BIND 8 compatibility).

    notify-source

    notify-source determines which local source address, and optionally UDP port, will be used to send NOTIFY messages. This address must appear in the slave server's masters zone clause or in an allow-notify clause. This statement sets the notify-source for all zones, but can be overridden on a per-zone or per-view basis by including a notify-source statement within the zone or view block in the configuration file.

    Note

    Solaris 2.5.1 and earlier does not support setting the source address for TCP sockets.

    notify-source-v6

    Like notify-source, but applies to notify messages sent to IPv6 addresses.

    UDP Port Lists

    use-v4-udp-ports, avoid-v4-udp-ports, use-v6-udp-ports, and avoid-v6-udp-ports specify a list of IPv4 and IPv6 UDP ports that will be used or not used as source ports for UDP messages. See the section called “Query Address” about how the available ports are determined. For example, with the following configuration 

    use-v6-udp-ports { range 32768 65535; };
avoid-v6-udp-ports { 40000; range 50000 60000; };

    UDP ports of IPv6 messages sent from named will be in one of the following ranges: 32768 to 39999, 40001 to 49999, and 60001 to 65535.

    avoid-v4-udp-ports and avoid-v6-udp-ports can be used to prevent named from choosing as its random source port a port that is blocked by your firewall or a port that is used by other applications; if a query went out with a source port blocked by a firewall, the answer would not get by the firewall and the name server would have to query again. Note: the desired range can also be represented only with use-v4-udp-ports and use-v6-udp-ports, and the avoid- options are redundant in that sense; they are provided for backward compatibility and to possibly simplify the port specification.

    Operating System Resource Limits

    The server's usage of many system resources can be limited. Scaled values are allowed when specifying resource limits. For example, 1G can be used instead of 1073741824 to specify a limit of one gigabyte. unlimited requests unlimited use, or the maximum available amount. default uses the limit that was in force when the server was started. See the description of size_spec in the section called “Configuration File Elements”.

    The following options set operating system resource limits for the name server process. Some operating systems don't support some or any of the limits. On such systems, a warning will be issued if the unsupported limit is used.

    coresize

    The maximum size of a core dump. The default is default.

    datasize

    The maximum amount of data memory the server may use. The default is default. This is a hard limit on server memory usage. If the server attempts to allocate memory in excess of this limit, the allocation will fail, which may in turn leave the server unable to perform DNS service. Therefore, this option is rarely useful as a way of limiting the amount of memory used by the server, but it can be used to raise an operating system data size limit that is too small by default. If you wish to limit the amount of memory used by the server, use the max-cache-size and recursive-clients options instead.

    files

    The maximum number of files the server may have open concurrently. The default is unlimited.

    stacksize

    The maximum amount of stack memory the server may use. The default is default.

    Server Resource Limits

    The following options set limits on the server's resource consumption that are enforced internally by the server rather than the operating system.

    max-ixfr-log-size

    This option is obsolete; it is accepted and ignored for BIND 8 compatibility. The option max-journal-size performs a similar function in BIND 9.

    max-journal-size

    Sets a maximum size for each journal file (see the section called “The journal file”). When the journal file approaches the specified size, some of the oldest transactions in the journal will be automatically removed. The default is unlimited. This may also be set on a per-zone basis.

    host-statistics-max

    In BIND 8, specifies the maximum number of host statistics entries to be kept. Not implemented in BIND 9.

    recursive-clients

    The maximum number of simultaneous recursive lookups the server will perform on behalf of clients. The default is 1000. Because each recursing client uses a fair bit of memory, on the order of 20 kilobytes, the value of the recursive-clients option may have to be decreased on hosts with limited memory.

    tcp-clients

    The maximum number of simultaneous client TCP connections that the server will accept. The default is 100.

    reserved-sockets

    The number of file descriptors reserved for TCP, stdio, etc. This needs to be big enough to cover the number of interfaces named listens on, tcp-clients as well as to provide room for outgoing TCP queries and incoming zone transfers. The default is 512. The minimum value is 128 and the maximum value is 128 less than maxsockets (-S). This option may be removed in the future.

    This option has little effect on Windows.

    max-cache-size

    The maximum amount of memory to use for the server's cache, in bytes. When the amount of data in the cache reaches this limit, the server will cause records to expire prematurely based on an LRU based strategy so that the limit is not exceeded. A value of 0 is special, meaning that records are purged from the cache only when their TTLs expire. Another special keyword unlimited means the maximum value of 32-bit unsigned integers (0xffffffff), which may not have the same effect as 0 on machines that support more than 32 bits of memory space. Any positive values less than 2MB will be ignored reset to 2MB. In a server with multiple views, the limit applies separately to the cache of each view. The default is 0.

    tcp-listen-queue

    The listen queue depth. The default and minimum is 3. If the kernel supports the accept filter "dataready" this also controls how many TCP connections that will be queued in kernel space waiting for some data before being passed to accept. Values less than 3 will be silently raised.

    Periodic Task Intervals

    cleaning-interval

    This interval is effectively obsolete. Previously, the server would remove expired resource records from the cache every cleaning-interval minutes. BIND 9 now manages cache memory in a more sophisticated manner and does not rely on the periodic cleaning any more. Specifying this option therefore has no effect on the server's behavior.

    heartbeat-interval

    The server will perform zone maintenance tasks for all zones marked as dialup whenever this interval expires. The default is 60 minutes. Reasonable values are up to 1 day (1440 minutes). The maximum value is 28 days (40320 minutes). If set to 0, no zone maintenance for these zones will occur.

    interface-interval

    The server will scan the network interface list every interface-interval minutes. The default is 60 minutes. The maximum value is 28 days (40320 minutes). If set to 0, interface scanning will only occur when the configuration file is loaded. After the scan, the server will begin listening for queries on any newly discovered interfaces (provided they are allowed by the listen-on configuration), and will stop listening on interfaces that have gone away.

    statistics-interval

    Name server statistics will be logged every statistics-interval minutes. The default is 60. The maximum value is 28 days (40320 minutes). If set to 0, no statistics will be logged.

    Note

    Not yet implemented in BIND 9.

    Topology

    All other things being equal, when the server chooses a name server to query from a list of name servers, it prefers the one that is topologically closest to itself. The topology statement takes an address_match_list and interprets it in a special way. Each top-level list element is assigned a distance. Non-negated elements get a distance based on their position in the list, where the closer the match is to the start of the list, the shorter the distance is between it and the server. A negated match will be assigned the maximum distance from the server. If there is no match, the address will get a distance which is further than any non-negated list element, and closer than any negated element. For example, 

    topology {
    10/8;
    !1.2.3/24;
    { 1.2/16; 3/8; };
};

    will prefer servers on network 10 the most, followed by hosts on network 1.2.0.0 (netmask 255.255.0.0) and network 3, with the exception of hosts on network 1.2.3 (netmask 255.255.255.0), which is preferred least of all.

    The default topology is 

        topology { localhost; localnets; };

    Note

    The topology option is not implemented in BIND 9.

    The sortlist Statement

    The response to a DNS query may consist of multiple resource records (RRs) forming a resource records set (RRset). The name server will normally return the RRs within the RRset in an indeterminate order (but see the rrset-order statement in the section called “RRset Ordering”). The client resolver code should rearrange the RRs as appropriate, that is, using any addresses on the local net in preference to other addresses. However, not all resolvers can do this or are correctly configured. When a client is using a local server, the sorting can be performed in the server, based on the client's address. This only requires configuring the name servers, not all the clients.

    The sortlist statement (see below) takes an address_match_list and interprets it even more specifically than the topology statement does (the section called “Topology”). Each top level statement in the sortlist must itself be an explicit address_match_list with one or two elements. The first element (which may be an IP address, an IP prefix, an ACL name or a nested address_match_list) of each top level list is checked against the source address of the query until a match is found.

    Once the source address of the query has been matched, if the top level statement contains only one element, the actual primitive element that matched the source address is used to select the address in the response to move to the beginning of the response. If the statement is a list of two elements, then the second element is treated the same as the address_match_list in a topology statement. Each top level element is assigned a distance and the address in the response with the minimum distance is moved to the beginning of the response.

    In the following example, any queries received from any of the addresses of the host itself will get responses preferring addresses on any of the locally connected networks. Next most preferred are addresses on the 192.168.1/24 network, and after that either the 192.168.2/24 or 192.168.3/24 network with no preference shown between these two networks. Queries received from a host on the 192.168.1/24 network will prefer other addresses on that network to the 192.168.2/24 and 192.168.3/24 networks. Queries received from a host on the 192.168.4/24 or the 192.168.5/24 network will only prefer other addresses on their directly connected networks. 

    sortlist {
    { localhost;                                   // IF   the local host
        { localnets;                               // THEN first fit on the
            192.168.1/24;                          //   following nets
            { 192.168.2/24; 192.168.3/24; }; }; };
    { 192.168.1/24;                                // IF   on class C 192.168.1
        { 192.168.1/24;                            // THEN use .1, or .2 or .3
            { 192.168.2/24; 192.168.3/24; }; }; };
    { 192.168.2/24;                                // IF   on class C 192.168.2
        { 192.168.2/24;                            // THEN use .2, or .1 or .3
            { 192.168.1/24; 192.168.3/24; }; }; };
    { 192.168.3/24;                                // IF   on class C 192.168.3
        { 192.168.3/24;                            // THEN use .3, or .1 or .2
            { 192.168.1/24; 192.168.2/24; }; }; };
    { { 192.168.4/24; 192.168.5/24; };             // if .4 or .5, prefer that net
    };
};

    The following example will give reasonable behavior for the local host and hosts on directly connected networks. It is similar to the behavior of the address sort in BIND 4.9.x. Responses sent to queries from the local host will favor any of the directly connected networks. Responses sent to queries from any other hosts on a directly connected network will prefer addresses on that same network. Responses to other queries will not be sorted. 

    sortlist {
           { localhost; localnets; };
           { localnets; };
};

    RRset Ordering

    When multiple records are returned in an answer it may be useful to configure the order of the records placed into the response. The rrset-order statement permits configuration of the ordering of the records in a multiple record response. See also the sortlist statement, the section called “The sortlist Statement”.

    An order_spec is defined as follows:

    [class class_name] [type type_name] [name "domain_name"] order ordering

    If no class is specified, the default is ANY. If no type is specified, the default is ANY. If no name is specified, the default is "*" (asterisk).

    The legal values for ordering are:

    fixed

    Records are returned in the order they are defined in the zone file.

    random

    Records are returned in some random order.

    cyclic

    Records are returned in a cyclic round-robin order.

    If BIND is configured with the "--enable-fixed-rrset" option at compile time, then the initial ordering of the RRset will match the one specified in the zone file.

    For example: 

    rrset-order {
   class IN type A name "host.example.com" order random;
   order cyclic;
};

    will cause any responses for type A records in class IN that have "host.example.com" as a suffix, to always be returned in random order. All other records are returned in cyclic order.

    If multiple rrset-order statements appear, they are not combined — the last one applies.

    Note

    In this release of BIND 9, the rrset-order statement does not support "fixed" ordering by default. Fixed ordering can be enabled at compile time by specifying "--enable-fixed-rrset" on the "configure" command line.

    Tuning

    lame-ttl

    Sets the number of seconds to cache a lame server indication. 0 disables caching. (This is NOT recommended.) The default is 600 (10 minutes) and the maximum value is 1800 (30 minutes).

    Lame-ttl also controls the amount of time DNSSEC validation failures are cached. There is a minimum of 30 seconds applied to bad cache entries if the lame-ttl is set to less than 30 seconds.

    max-ncache-ttl

    To reduce network traffic and increase performance, the server stores negative answers. max-ncache-ttl is used to set a maximum retention time for these answers in the server in seconds. The default max-ncache-ttl is 10800 seconds (3 hours). max-ncache-ttl cannot exceed 7 days and will be silently truncated to 7 days if set to a greater value.

    max-cache-ttl

    Sets the maximum time for which the server will cache ordinary (positive) answers. The default is one week (7 days). A value of zero may cause all queries to return SERVFAIL, because of lost caches of intermediate RRsets (such as NS and glue AAAA/A records) in the resolution process.

    min-roots

    The minimum number of root servers that is required for a request for the root servers to be accepted. The default is 2.

    Note

    Not implemented in BIND 9.

    sig-validity-interval

    Specifies the number of days into the future when DNSSEC signatures automatically generated as a result of dynamic updates (the section called “Dynamic Update”) will expire. There is a optional second field which specifies how long before expiry that the signatures will be regenerated. If not specified, the signatures will be regenerated at 1/4 of base interval. The second field is specified in days if the base interval is greater than 7 days otherwise it is specified in hours. The default base interval is 30 days giving a re-signing interval of 7 1/2 days. The maximum values are 10 years (3660 days).

    The signature inception time is unconditionally set to one hour before the current time to allow for a limited amount of clock skew.

    The sig-validity-interval should be, at least, several multiples of the SOA expire interval to allow for reasonable interaction between the various timer and expiry dates.

    sig-signing-nodes

    Specify the maximum number of nodes to be examined in each quantum when signing a zone with a new DNSKEY. The default is 100.

    sig-signing-signatures

    Specify a threshold number of signatures that will terminate processing a quantum when signing a zone with a new DNSKEY. The default is 10.

    sig-signing-type

    Specify a private RDATA type to be used when generating key signing records. The default is 65534.

    It is expected that this parameter may be removed in a future version once there is a standard type.

    min-refresh-time, max-refresh-time, min-retry-time, max-retry-time

    These options control the server's behavior on refreshing a zone (querying for SOA changes) or retrying failed transfers. Usually the SOA values for the zone are used, but these values are set by the master, giving slave server administrators little control over their contents.

    These options allow the administrator to set a minimum and maximum refresh and retry time either per-zone, per-view, or globally. These options are valid for slave and stub zones, and clamp the SOA refresh and retry times to the specified values.

    The following defaults apply. min-refresh-time 300 seconds, max-refresh-time 2419200 seconds (4 weeks), min-retry-time 500 seconds, and max-retry-time 1209600 seconds (2 weeks).

    edns-udp-size

    Sets the advertised EDNS UDP buffer size in bytes to control the size of packets received. Valid values are 512 to 4096 (values outside this range will be silently adjusted). The default value is 4096. The usual reason for setting edns-udp-size to a non-default value is to get UDP answers to pass through broken firewalls that block fragmented packets and/or block UDP packets that are greater than 512 bytes.

    max-udp-size

    Sets the maximum EDNS UDP message size named will send in bytes. Valid values are 512 to 4096 (values outside this range will be silently adjusted). The default value is 4096. The usual reason for setting max-udp-size to a non-default value is to get UDP answers to pass through broken firewalls that block fragmented packets and/or block UDP packets that are greater than 512 bytes. This is independent of the advertised receive buffer (edns-udp-size).

    masterfile-format

    Specifies the file format of zone files (see the section called “Additional File Formats”). The default value is text, which is the standard textual representation. Files in other formats than text are typically expected to be generated by the named-compilezone tool. Note that when a zone file in a different format than text is loaded, named may omit some of the checks which would be performed for a file in the text format. In particular, check-names checks do not apply for the raw format. This means a zone file in the raw format must be generated with the same check level as that specified in the named configuration file. This statement sets the masterfile-format for all zones, but can be overridden on a per-zone or per-view basis by including a masterfile-format statement within the zone or view block in the configuration file.

    clients-per-query, max-clients-per-query

    These set the initial value (minimum) and maximum number of recursive simultaneous clients for any given query (<qname,qtype,qclass>) that the server will accept before dropping additional clients. named will attempt to self tune this value and changes will be logged. The default values are 10 and 100.

    This value should reflect how many queries come in for a given name in the time it takes to resolve that name. If the number of queries exceed this value, named will assume that it is dealing with a non-responsive zone and will drop additional queries. If it gets a response after dropping queries, it will raise the estimate. The estimate will then be lowered in 20 minutes if it has remained unchanged.

    If clients-per-query is set to zero, then there is no limit on the number of clients per query and no queries will be dropped.

    If max-clients-per-query is set to zero, then there is no upper bound other than imposed by recursive-clients.

    notify-delay

    The delay, in seconds, between sending sets of notify messages for a zone. The default is five (5) seconds.

    The overall rate that NOTIFY messages are sent for all zones is controlled by serial-query-rate.

    Built-in server information zones

    The server provides some helpful diagnostic information through a number of built-in zones under the pseudo-top-level-domain bind in the CHAOS class. These zones are part of a built-in view (see the section called “view Statement Grammar”) of class CHAOS which is separate from the default view of class IN; therefore, any global server options such as allow-query do not apply the these zones. If you feel the need to disable these zones, use the options below, or hide the built-in CHAOS view by defining an explicit view of class CHAOS that matches all clients.

    version

    The version the server should report via a query of the name version.bind with type TXT, class CHAOS. The default is the real version number of this server. Specifying version none disables processing of the queries.

    hostname

    The hostname the server should report via a query of the name hostname.bind with type TXT, class CHAOS. This defaults to the hostname of the machine hosting the name server as found by the gethostname() function. The primary purpose of such queries is to identify which of a group of anycast servers is actually answering your queries. Specifying hostname none; disables processing of the queries.

    server-id

    The ID the server should report when receiving a Name Server Identifier (NSID) query, or a query of the name ID.SERVER with type TXT, class CHAOS. The primary purpose of such queries is to identify which of a group of anycast servers is actually answering your queries. Specifying server-id none; disables processing of the queries. Specifying server-id hostname; will cause named to use the hostname as found by the gethostname() function. The default server-id is none.

    Built-in Empty Zones

    Named has some built-in empty zones (SOA and NS records only). These are for zones that should normally be answered locally and which queries should not be sent to the Internet's root servers. The official servers which cover these namespaces return NXDOMAIN responses to these queries. In particular, these cover the reverse namespaces for addresses from RFC 1918, RFC 4193, and RFC 5737. They also include the reverse namespace for IPv6 local address (locally assigned), IPv6 link local addresses, the IPv6 loopback address and the IPv6 unknown address.

    Named will attempt to determine if a built-in zone already exists or is active (covered by a forward-only forwarding declaration) and will not create a empty zone in that case.

    The current list of empty zones is:

    • 10.IN-ADDR.ARPA
    • 16.172.IN-ADDR.ARPA
    • 17.172.IN-ADDR.ARPA
    • 18.172.IN-ADDR.ARPA
    • 19.172.IN-ADDR.ARPA
    • 20.172.IN-ADDR.ARPA
    • 21.172.IN-ADDR.ARPA
    • 22.172.IN-ADDR.ARPA
    • 23.172.IN-ADDR.ARPA
    • 24.172.IN-ADDR.ARPA
    • 25.172.IN-ADDR.ARPA
    • 26.172.IN-ADDR.ARPA
    • 27.172.IN-ADDR.ARPA
    • 28.172.IN-ADDR.ARPA
    • 29.172.IN-ADDR.ARPA
    • 30.172.IN-ADDR.ARPA
    • 31.172.IN-ADDR.ARPA
    • 168.192.IN-ADDR.ARPA
    • 0.IN-ADDR.ARPA
    • 127.IN-ADDR.ARPA
    • 254.169.IN-ADDR.ARPA
    • 2.0.192.IN-ADDR.ARPA
    • 100.51.198.IN-ADDR.ARPA
    • 113.0.203.IN-ADDR.ARPA
    • 255.255.255.255.IN-ADDR.ARPA
    • 0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA
    • 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA
    • 8.B.D.0.1.0.0.2.IP6.ARPA
    • D.F.IP6.ARPA
    • 8.E.F.IP6.ARPA
    • 9.E.F.IP6.ARPA
    • A.E.F.IP6.ARPA
    • B.E.F.IP6.ARPA

    Empty zones are settable at the view level and only apply to views of class IN. Disabled empty zones are only inherited from options if there are no disabled empty zones specified at the view level. To override the options list of disabled zones, you can disable the root zone at the view level, for example: 

                disable-empty-zone ".";

    If you are using the address ranges covered here, you should already have reverse zones covering the addresses you use. In practice this appears to not be the case with many queries being made to the infrastructure servers for names in these spaces. So many in fact that sacrificial servers were needed to be deployed to channel the query load away from the infrastructure servers.

    Note

    The real parent servers for these zones should disable all empty zone under the parent zone they serve. For the real root servers, this is all built-in empty zones. This will enable them to return referrals to deeper in the tree.
    empty-server

    Specify what server name will appear in the returned SOA record for empty zones. If none is specified, then the zone's name will be used.

    empty-contact

    Specify what contact name will appear in the returned SOA record for empty zones. If none is specified, then "." will be used.

    empty-zones-enable

    Enable or disable all empty zones. By default, they are enabled.

    disable-empty-zone

    Disable individual empty zones. By default, none are disabled. This option can be specified multiple times.

    Additional Section Caching

    The additional section cache, also called acache, is an internal cache to improve the response performance of BIND 9. When additional section caching is enabled, BIND 9 will cache an internal short-cut to the additional section content for each answer RR. Note that acache is an internal caching mechanism of BIND 9, and is not related to the DNS caching server function.

    Additional section caching does not change the response content (except the RRsets ordering of the additional section, see below), but can improve the response performance significantly. It is particularly effective when BIND 9 acts as an authoritative server for a zone that has many delegations with many glue RRs.

    In order to obtain the maximum performance improvement from additional section caching, setting additional-from-cache to no is recommended, since the current implementation of acache does not short-cut of additional section information from the DNS cache data.

    One obvious disadvantage of acache is that it requires much more memory for the internal cached data. Thus, if the response performance does not matter and memory consumption is much more critical, the acache mechanism can be disabled by setting acache-enable to no. It is also possible to specify the upper limit of memory consumption for acache by using max-acache-size.

    Additional section caching also has a minor effect on the RRset ordering in the additional section. Without acache, cyclic order is effective for the additional section as well as the answer and authority sections. However, additional section caching fixes the ordering when it first caches an RRset for the additional section, and the same ordering will be kept in succeeding responses, regardless of the setting of rrset-order. The effect of this should be minor, however, since an RRset in the additional section typically only contains a small number of RRs (and in many cases it only contains a single RR), in which case the ordering does not matter much.

    The following is a summary of options related to acache.

    acache-enable

    If yes, additional section caching is enabled. The default value is no.

    acache-cleaning-interval

    The server will remove stale cache entries, based on an LRU based algorithm, every acache-cleaning-interval minutes. The default is 60 minutes. If set to 0, no periodic cleaning will occur.

    max-acache-size

    The maximum amount of memory in bytes to use for the server's acache. When the amount of data in the acache reaches this limit, the server will clean more aggressively so that the limit is not exceeded. In a server with multiple views, the limit applies separately to the acache of each view. The default is 16M.

    server Statement Definition and Usage

    The server statement defines characteristics to be associated with a remote name server. If a prefix length is specified, then a range of servers is covered. Only the most specific server clause applies regardless of the order in named.conf.

    The server statement can occur at the top level of the configuration file or inside a view statement. If a view statement contains one or more server statements, only those apply to the view and any top-level ones are ignored. If a view contains no server statements, any top-level server statements are used as defaults.

    If you discover that a remote server is giving out bad data, marking it as bogus will prevent further queries to it. The default value of bogus is no.

    The provide-ixfr clause determines whether the local server, acting as master, will respond with an incremental zone transfer when the given remote server, a slave, requests it. If set to yes, incremental transfer will be provided whenever possible. If set to no, all transfers to the remote server will be non-incremental. If not set, the value of the provide-ixfr option in the view or global options block is used as a default.

    The request-ixfr clause determines whether the local server, acting as a slave, will request incremental zone transfers from the given remote server, a master. If not set, the value of the request-ixfr option in the view or global options block is used as a default.

    IXFR requests to servers that do not support IXFR will automatically fall back to AXFR. Therefore, there is no need to manually list which servers support IXFR and which ones do not; the global default of yes should always work. The purpose of the provide-ixfr and request-ixfr clauses is to make it possible to disable the use of IXFR even when both master and slave claim to support it, for example if one of the servers is buggy and crashes or corrupts data when IXFR is used.

    The edns clause determines whether the local server will attempt to use EDNS when communicating with the remote server. The default is yes.

    The edns-udp-size option sets the EDNS UDP size that is advertised by named when querying the remote server. Valid values are 512 to 4096 bytes (values outside this range will be silently adjusted). This option is useful when you wish to advertises a different value to this server than the value you advertise globally, for example, when there is a firewall at the remote site that is blocking large replies.

    The max-udp-size option sets the maximum EDNS UDP message size named will send. Valid values are 512 to 4096 bytes (values outside this range will be silently adjusted). This option is useful when you know that there is a firewall that is blocking large replies from named.

    The server supports two zone transfer methods. The first, one-answer, uses one DNS message per resource record transferred. many-answers packs as many resource records as possible into a message. many-answers is more efficient, but is only known to be understood by BIND 9, BIND 8.x, and patched versions of BIND 4.9.5. You can specify which method to use for a server with the transfer-format option. If transfer-format is not specified, the transfer-format specified by the options statement will be used.

    transfers is used to limit the number of concurrent inbound zone transfers from the specified server. If no transfers clause is specified, the limit is set according to the transfers-per-ns option.

    The keys clause identifies a key_id defined by the key statement, to be used for transaction security (TSIG, the section called “TSIG”) when talking to the remote server. When a request is sent to the remote server, a request signature will be generated using the key specified here and appended to the message. A request originating from the remote server is not required to be signed by this key.

    Although the grammar of the keys clause allows for multiple keys, only a single key per server is currently supported.

    The transfer-source and transfer-source-v6 clauses specify the IPv4 and IPv6 source address to be used for zone transfer with the remote server, respectively. For an IPv4 remote server, only transfer-source can be specified. Similarly, for an IPv6 remote server, only transfer-source-v6 can be specified. For more details, see the description of transfer-source and transfer-source-v6 in the section called “Zone Transfers”.

    The notify-source and notify-source-v6 clauses specify the IPv4 and IPv6 source address to be used for notify messages sent to remote servers, respectively. For an IPv4 remote server, only notify-source can be specified. Similarly, for an IPv6 remote server, only notify-source-v6 can be specified.

    The query-source and query-source-v6 clauses specify the IPv4 and IPv6 source address to be used for queries sent to remote servers, respectively. For an IPv4 remote server, only query-source can be specified. Similarly, for an IPv6 remote server, only query-source-v6 can be specified.

    statistics-channels Statement Grammar

    statistics-channels {
   [ inet ( ip_addr | * ) [ port ip_port ] [allow {  address_match_list  } ]; ]
   [ inet ...; ]
};

    statistics-channels Statement Definition and Usage

    The statistics-channels statement declares communication channels to be used by system administrators to get access to statistics information of the name server.

    This statement intends to be flexible to support multiple communication protocols in the future, but currently only HTTP access is supported. It requires that BIND 9 be compiled with libxml2; the statistics-channels statement is still accepted even if it is built without the library, but any HTTP access will fail with an error.

    An inet control channel is a TCP socket listening at the specified ip_port on the specified ip_addr, which can be an IPv4 or IPv6 address. An ip_addr of * (asterisk) is interpreted as the IPv4 wildcard address; connections will be accepted on any of the system's IPv4 addresses. To listen on the IPv6 wildcard address, use an ip_addr of ::.

    If no port is specified, port 80 is used for HTTP channels. The asterisk "*" cannot be used for ip_port.

    The attempt of opening a statistics channel is restricted by the optional allow clause. Connections to the statistics channel are permitted based on the address_match_list. If no allow clause is present, named accepts connection attempts from any address; since the statistics may contain sensitive internal information, it is highly recommended to restrict the source of connection requests appropriately.

    If no statistics-channels statement is present, named will not open any communication channels.

    trusted-keys Statement Grammar

    trusted-keys {
    string number number number string ;
    [ string number number number string ; [...]]
};

    trusted-keys Statement Definition and Usage

    The trusted-keys statement defines DNSSEC security roots. DNSSEC is described in the section called “DNSSEC”. A security root is defined when the public key for a non-authoritative zone is known, but cannot be securely obtained through DNS, either because it is the DNS root zone or because its parent zone is unsigned. Once a key has been configured as a trusted key, it is treated as if it had been validated and proven secure. The resolver attempts DNSSEC validation on all DNS data in subdomains of a security root.

    All keys (and corresponding zones) listed in trusted-keys are deemed to exist regardless of what parent zones say. Similarly for all keys listed in trusted-keys only those keys are used to validate the DNSKEY RRset. The parent's DS RRset will not be used.

    The trusted-keys statement can contain multiple key entries, each consisting of the key's domain name, flags, protocol, algorithm, and the Base-64 representation of the key data. Spaces, tabs, newlines and carriage returns are ignored in the key data, so the configuration may be split up into multiple lines.

    view Statement Grammar

    view view_name
      [class] {
      match-clients { address_match_list };
      match-destinations { address_match_list };
      match-recursive-only yes_or_no ;
      [ view_option; ...]
      [ zone_statement; ...]
};

    view Statement Definition and Usage

    The view statement is a powerful feature of BIND 9 that lets a name server answer a DNS query differently depending on who is asking. It is particularly useful for implementing split DNS setups without having to run multiple servers.

    Each view statement defines a view of the DNS namespace that will be seen by a subset of clients. A client matches a view if its source IP address matches the address_match_list of the view's match-clients clause and its destination IP address matches the address_match_list of the view's match-destinations clause. If not specified, both match-clients and match-destinations default to matching all addresses. In addition to checking IP addresses match-clients and match-destinations can also take keys which provide an mechanism for the client to select the view. A view can also be specified as match-recursive-only, which means that only recursive requests from matching clients will match that view. The order of the view statements is significant — a client request will be resolved in the context of the first view that it matches.

    Zones defined within a view statement will only be accessible to clients that match the view. By defining a zone of the same name in multiple views, different zone data can be given to different clients, for example, "internal" and "external" clients in a split DNS setup.

    Many of the options given in the options statement can also be used within a view statement, and then apply only when resolving queries with that view. When no view-specific value is given, the value in the options statement is used as a default. Also, zone options can have default values specified in the view statement; these view-specific defaults take precedence over those in the options statement.

    Views are class specific. If no class is given, class IN is assumed. Note that all non-IN views must contain a hint zone, since only the IN class has compiled-in default hints.

    If there are no view statements in the config file, a default view that matches any client is automatically created in class IN. Any zone statements specified on the top level of the configuration file are considered to be part of this default view, and the options statement will apply to the default view. If any explicit view statements are present, all zone statements must occur inside view statements.

    Here is an example of a typical split DNS setup implemented using view statements: 

    view "internal" {
      // This should match our internal networks.
      match-clients { 10.0.0.0/8; };

      // Provide recursive service to internal clients only.
      recursion yes;

      // Provide a complete view of the example.com zone
      // including addresses of internal hosts.
      zone "example.com" {
            type master;
            file "example-internal.db";
      };
};

view "external" {
      // Match all clients not matched by the previous view.
      match-clients { any; };

      // Refuse recursive service to external clients.
      recursion no;

      // Provide a restricted view of the example.com zone
      // containing only publicly accessible hosts.
      zone "example.com" {
           type master;
           file "example-external.db";
      };
};

    zone Statement Definition and Usage

    Zone Types

    master

    The server has a master copy of the data for the zone and will be able to provide authoritative answers for it.

    slave

    A slave zone is a replica of a master zone. The masters list specifies one or more IP addresses of master servers that the slave contacts to update its copy of the zone. Masters list elements can also be names of other masters lists. By default, transfers are made from port 53 on the servers; this can be changed for all servers by specifying a port number before the list of IP addresses, or on a per-server basis after the IP address. Authentication to the master can also be done with per-server TSIG keys. If a file is specified, then the replica will be written to this file whenever the zone is changed, and reloaded from this file on a server restart. Use of a file is recommended, since it often speeds server startup and eliminates a needless waste of bandwidth. Note that for large numbers (in the tens or hundreds of thousands) of zones per server, it is best to use a two-level naming scheme for zone filenames. For example, a slave server for the zone example.com might place the zone contents into a file called ex/example.com where ex/ is just the first two letters of the zone name. (Most operating systems behave very slowly if you put 100000 files into a single directory.)

    stub

    A stub zone is similar to a slave zone, except that it replicates only the NS records of a master zone instead of the entire zone. Stub zones are not a standard part of the DNS; they are a feature specific to the BIND implementation.

    Stub zones can be used to eliminate the need for glue NS record in a parent zone at the expense of maintaining a stub zone entry and a set of name server addresses in named.conf. This usage is not recommended for new configurations, and BIND 9 supports it only in a limited way. In BIND 4/8, zone transfers of a parent zone included the NS records from stub children of that zone. This meant that, in some cases, users could get away with configuring child stubs only in the master server for the parent zone. BIND 9 never mixes together zone data from different zones in this way. Therefore, if a BIND 9 master serving a parent zone has child stub zones configured, all the slave servers for the parent zone also need to have the same child stub zones configured.

    Stub zones can also be used as a way of forcing the resolution of a given domain to use a particular set of authoritative servers. For example, the caching name servers on a private network using RFC1918 addressing may be configured with stub zones for 10.in-addr.arpa to use a set of internal name servers as the authoritative servers for that domain.

    forward

    A "forward zone" is a way to configure forwarding on a per-domain basis. A zone statement of type forward can contain a forward and/or forwarders statement, which will apply to queries within the domain given by the zone name. If no forwarders statement is present or an empty list for forwarders is given, then no forwarding will be done for the domain, canceling the effects of any forwarders in the options statement. Thus if you want to use this type of zone to change the behavior of the global forward option (that is, "forward first" to, then "forward only", or vice versa, but want to use the same servers as set globally) you need to re-specify the global forwarders.

    hint

    The initial set of root name servers is specified using a "hint zone". When the server starts up, it uses the root hints to find a root name server and get the most recent list of root name servers. If no hint zone is specified for class IN, the server uses a compiled-in default set of root servers hints. Classes other than IN have no built-in defaults hints.

    delegation-only

    This is used to enforce the delegation-only status of infrastructure zones (e.g. COM, NET, ORG). Any answer that is received without an explicit or implicit delegation in the authority section will be treated as NXDOMAIN. This does not apply to the zone apex. This should not be applied to leaf zones.

    delegation-only has no effect on answers received from forwarders.

    See caveats in root-delegation-only.

    Class

    The zone's name may optionally be followed by a class. If a class is not specified, class IN (for Internet), is assumed. This is correct for the vast majority of cases.

    The hesiod class is named for an information service from MIT's Project Athena. It is used to share information about various systems databases, such as users, groups, printers and so on. The keyword HS is a synonym for hesiod.

    Another MIT development is Chaosnet, a LAN protocol created in the mid-1970s. Zone data for it can be specified with the CHAOS class.

    Zone Options

    allow-notify

    See the description of allow-notify in the section called “Access Control”.

    allow-query

    See the description of allow-query in the section called “Access Control”.

    allow-query-on

    See the description of allow-query-on in the section called “Access Control”.

    allow-transfer

    See the description of allow-transfer in the section called “Access Control”.

    allow-update

    See the description of allow-update in the section called “Access Control”.

    update-policy

    Specifies a "Simple Secure Update" policy. See the section called “Dynamic Update Policies”.

    allow-update-forwarding

    See the description of allow-update-forwarding in the section called “Access Control”.

    also-notify

    Only meaningful if notify is active for this zone. The set of machines that will receive a DNS NOTIFY message for this zone is made up of all the listed name servers (other than the primary master) for the zone plus any IP addresses specified with also-notify. A port may be specified with each also-notify address to send the notify messages to a port other than the default of 53. also-notify is not meaningful for stub zones. The default is the empty list.

    check-names

    This option is used to restrict the character set and syntax of certain domain names in master files and/or DNS responses received from the network. The default varies according to zone type. For master zones the default is fail. For slave zones the default is warn.

    check-mx

    See the description of check-mx in the section called “Boolean Options”.

    check-wildcard

    See the description of check-wildcard in the section called “Boolean Options”.

    check-integrity

    See the description of check-integrity in the section called “Boolean Options”.

    check-sibling

    See the description of check-sibling in the section called “Boolean Options”.

    zero-no-soa-ttl

    See the description of zero-no-soa-ttl in the section called “Boolean Options”.

    update-check-ksk

    See the description of update-check-ksk in the section called “Boolean Options”.

    try-tcp-refresh

    See the description of try-tcp-refresh in the section called “Boolean Options”.

    database

    Specify the type of database to be used for storing the zone data. The string following the database keyword is interpreted as a list of whitespace-delimited words. The first word identifies the database type, and any subsequent words are passed as arguments to the database to be interpreted in a way specific to the database type.

    The default is "rbt", BIND 9's native in-memory red-black-tree database. This database does not take arguments.

    Other values are possible if additional database drivers have been linked into the server. Some sample drivers are included with the distribution but none are linked in by default.

    dialup

    See the description of dialup in the section called “Boolean Options”.

    delegation-only

    The flag only applies to hint and stub zones. If set to yes, then the zone will also be treated as if it is also a delegation-only type zone.

    See caveats in root-delegation-only.

    forward

    Only meaningful if the zone has a forwarders list. The only value causes the lookup to fail after trying the forwarders and getting no answer, while first would allow a normal lookup to be tried.

    forwarders

    Used to override the list of global forwarders. If it is not specified in a zone of type forward, no forwarding is done for the zone and the global options are not used.

    ixfr-base

    Was used in BIND 8 to specify the name of the transaction log (journal) file for dynamic update and IXFR. BIND 9 ignores the option and constructs the name of the journal file by appending ".jnl" to the name of the zone file.

    ixfr-tmp-file

    Was an undocumented option in BIND 8. Ignored in BIND 9.

    journal

    Allow the default journal's filename to be overridden. The default is the zone's filename with ".jnl" appended. This is applicable to master and slave zones.

    max-journal-size

    See the description of max-journal-size in the section called “Server Resource Limits”.

    max-transfer-time-in

    See the description of notify-delay in the section called “Tuning”.

    notify-to-soa

    See the description of notify-to-soa in the section called “Boolean Options”.

    pubkey

    In BIND 8, this option was intended for specifying a public zone key for verification of signatures in DNSSEC signed zones when they are loaded from disk. BIND 9 does not verify signatures on load and ignores the option.

    zone-statistics

    If yes, the server will keep statistical information for this zone, which can be dumped to the statistics-file defined in the server options.

    sig-validity-interval

    See the description of sig-validity-interval in the section called “Tuning”.

    sig-signing-nodes

    See the description of sig-signing-nodes in the section called “Tuning”.

    masterfile-format

    See the description of masterfile-format in the section called “Tuning”.

    Dynamic Update Policies

    BIND 9 supports two alternative methods of granting clients the right to perform dynamic updates to a zone, configured by the allow-update and update-policy option, respectively.

    The allow-update clause works the same way as in previous versions of BIND. It grants given clients the permission to update any record of any name in the zone.

    The update-policy clause is new in BIND 9 and allows more fine-grained control over what updates are allowed. A set of rules is specified, where each rule either grants or denies permissions for one or more names to be updated by one or more identities. If the dynamic update request message is signed (that is, it includes either a TSIG or SIG(0) record), the identity of the signer can be determined.

    Rules are specified in the update-policy zone option, and are only meaningful for master zones. When the update-policy statement is present, it is a configuration error for the allow-update statement to be present. The update-policy statement only examines the signer of a message; the source address is not relevant.

    This is how a rule definition looks: 

    ( grant | deny ) identity nametype name [ types ]

    Each rule grants or denies privileges. Once a message has successfully matched a rule, the operation is immediately granted or denied and no further rules are examined. A rule is matched when the signer matches the identity field, the name matches the name field in accordance with the nametype field, and the type matches the types specified in the type field.

    No signer is required for tcp-self or 6to4-self however the standard reverse mapping / prefix conversion must match the identity field.

    The identity field specifies a name or a wildcard name. Normally, this is the name of the TSIG or SIG(0) key used to sign the update request. When a TKEY exchange has been used to create a shared secret, the identity of the shared secret is the same as the identity of the key used to authenticate the TKEY exchange. TKEY is also the negotiation method used by GSS-TSIG, which establishes an identity that is the Kerberos principal of the client, such as "user@host.domain". When the identity field specifies a wildcard name, it is subject to DNS wildcard expansion, so the rule will apply to multiple identities. The identity field must contain a fully-qualified domain name.

    For nametypes krb5-self, ms-self, krb5-subdomain, and ms-subdomain the identity field specifies the Windows or Kerberos realm of the machine belongs to.

    The nametype field has 12 values: name, subdomain, wildcard, self, selfsub, selfwild, krb5-self, ms-self, krb5-subdomain, ms-subdomain, tcp-self and 6to4-self.

    name

    Exact-match semantics. This rule matches when the name being updated is identical to the contents of the name field.

    subdomain

    This rule matches when the name being updated is a subdomain of, or identical to, the contents of the name field.

    wildcard

    The name field is subject to DNS wildcard expansion, and this rule matches when the name being updated name is a valid expansion of the wildcard.

    self

    This rule matches when the name being updated matches the contents of the identity field. The name field is ignored, but should be the same as the identity field. The self nametype is most useful when allowing using one key per name to update, where the key has the same name as the name to be updated. The identity would be specified as * (an asterisk) in this case.

    selfsub

    This rule is similar to self except that subdomains of self can also be updated.

    selfwild

    This rule is similar to self except that only subdomains of self can be updated.

    ms-self

    This rule takes a Windows machine principal (machine$@REALM) for machine in REALM and and converts it machine.realm allowing the machine to update machine.realm. The REALM to be matched is specified in the <replacable>identity</replacable> field.

    ms-subdomain

    This rule takes a Windows machine principal (machine$@REALM) for machine in REALM and converts it to machine.realm allowing the machine to update subdomains of machine.realm. The REALM to be matched is specified in the <replacable>identity</replacable> field.

    krb5-self

    This rule takes a Kerberos machine principal (host/machine@REALM) for machine in REALM and and converts it machine.realm allowing the machine to update machine.realm. The REALM to be matched is specified in the <replacable>identity</replacable> field.

    krb5-subdomain

    This rule takes a Kerberos machine principal (host/machine@REALM) for machine in REALM and converts it to machine.realm allowing the machine to update subdomains of machine.realm. The REALM to be matched is specified in the <replacable>identity</replacable> field.

    tcp-self

    Allow updates that have been sent via TCP and for which the standard mapping from the initiating IP address into the IN-ADDR.ARPA and IP6.ARPA namespaces match the name to be updated.

    Note

    It is theoretically possible to spoof these TCP sessions.

    6to4-self

    Allow the 6to4 prefix to be update by any TCP conection from the 6to4 network or from the corresponding IPv4 address. This is intended to allow NS or DNAME RRsets to be added to the reverse tree.

    Note

    It is theoretically possible to spoof these TCP sessions.

    In all cases, the name field must specify a fully-qualified domain name.

    If no types are explicitly specified, this rule matches all types except RRSIG, NS, SOA, NSEC and NSEC3. Types may be specified by name, including "ANY" (ANY matches all types except NSEC and NSEC3, which can never be updated). Note that when an attempt is made to delete all records associated with a name, the rules are checked for each existing record type.

    Types of Resource Records and When to Use Them

    This section, largely borrowed from RFC 1034, describes the concept of a Resource Record (RR) and explains when each is used. Since the publication of RFC 1034, several new RRs have been identified and implemented in the DNS. These are also included.

    Resource Records

    A domain name identifies a node. Each node has a set of resource information, which may be empty. The set of resource information associated with a particular name is composed of separate RRs. The order of RRs in a set is not significant and need not be preserved by name servers, resolvers, or other parts of the DNS. However, sorting of multiple RRs is permitted for optimization purposes, for example, to specify that a particular nearby server be tried first. See the section called “The sortlist Statement” and the section called “RRset Ordering”.

    The components of a Resource Record are:

    owner name

    The domain name where the RR is found.

    type

    An encoded 16-bit value that specifies the type of the resource record.

    TTL

    The time-to-live of the RR. This field is a 32-bit integer in units of seconds, and is primarily used by resolvers when they cache RRs. The TTL describes how long a RR can be cached before it should be discarded.

    class

    An encoded 16-bit value that identifies a protocol family or instance of a protocol.

    RDATA

    The resource data. The format of the data is type (and sometimes class) specific.

    The following are types of valid RRs:

    A

    A host address. In the IN class, this is a 32-bit IP address. Described in RFC 1035.

    AAAA

    IPv6 address. Described in RFC 1886.

    A6

    IPv6 address. This can be a partial address (a suffix) and an indirection to the name where the rest of the address (the prefix) can be found. Experimental. Described in RFC 2874.

    AFSDB

    Location of AFS database servers. Experimental. Described in RFC 1183.

    APL

    Address prefix list. Experimental. Described in RFC 3123.

    CERT

    Holds a digital certificate. Described in RFC 2538.

    CNAME

    Identifies the canonical name of an alias. Described in RFC 1035.

    DHCID

    Is used for identifying which DHCP client is associated with this name. Described in RFC 4701.

    DNAME

    Replaces the domain name specified with another name to be looked up, effectively aliasing an entire subtree of the domain name space rather than a single record as in the case of the CNAME RR. Described in RFC 2672.

    DNSKEY

    Stores a public key associated with a signed DNS zone. Described in RFC 4034.

    DS

    Stores the hash of a public key associated with a signed DNS zone. Described in RFC 4034.

    GPOS

    Specifies the global position. Superseded by LOC.

    HINFO

    Identifies the CPU and OS used by a host. Described in RFC 1035.

    IPSECKEY

    Provides a method for storing IPsec keying material in DNS. Described in RFC 4025.

    ISDN

    Representation of ISDN addresses. Experimental. Described in RFC 1183.

    KEY

    Stores a public key associated with a DNS name. Used in original DNSSEC; replaced by DNSKEY in DNSSECbis, but still used with SIG(0). Described in RFCs 2535 and 2931.

    KX

    Identifies a key exchanger for this DNS name. Described in RFC 2230.

    LOC

    For storing GPS info. Described in RFC 1876. Experimental.

    MX

    Identifies a mail exchange for the domain with a 16-bit preference value (lower is better) followed by the host name of the mail exchange. Described in RFC 974, RFC 1035.

    NAPTR

    Name authority pointer. Described in RFC 2915.

    NSAP

    A network service access point. Described in RFC 1706.

    NS

    The authoritative name server for the domain. Described in RFC 1035.

    NSEC

    Used in DNSSECbis to securely indicate that RRs with an owner name in a certain name interval do not exist in a zone and indicate what RR types are present for an existing name. Described in RFC 4034.

    NSEC3

    Used in DNSSECbis to securely indicate that RRs with an owner name in a certain name interval do not exist in a zone and indicate what RR types are present for an existing name. NSEC3 differs from NSEC in that it prevents zone enumeration but is more computationally expensive on both the server and the client than NSEC. Described in RFC 5155.

    NSEC3PARAM

    Used in DNSSECbis to tell the authoritative server which NSEC3 chains are available to use. Described in RFC 5155.

    NXT

    Used in DNSSEC to securely indicate that RRs with an owner name in a certain name interval do not exist in a zone and indicate what RR types are present for an existing name. Used in original DNSSEC; replaced by NSEC in DNSSECbis. Described in RFC 2535.

    PTR

    A pointer to another part of the domain name space. Described in RFC 1035.

    PX

    Provides mappings between RFC 822 and X.400 addresses. Described in RFC 2163.

    RP

    Information on persons responsible for the domain. Experimental. Described in RFC 1183.

    RRSIG

    Contains DNSSECbis signature data. Described in RFC 4034.

    RT

    Route-through binding for hosts that do not have their own direct wide area network addresses. Experimental. Described in RFC 1183.

    SIG

    Contains DNSSEC signature data. Used in original DNSSEC; replaced by RRSIG in DNSSECbis, but still used for SIG(0). Described in RFCs 2535 and 2931.

    SOA

    Identifies the start of a zone of authority. Described in RFC 1035.

    SPF

    Contains the Sender Policy Framework information for a given email domain. Described in RFC 4408.

    SRV

    Information about well known network services (replaces WKS). Described in RFC 2782.

    SSHFP

    Provides a way to securely publish a secure shell key's fingerprint. Described in RFC 4255.

    TXT

    Text records. Described in RFC 1035.

    WKS

    Information about which well known network services, such as SMTP, that a domain supports. Historical.

    X25

    Representation of X.25 network addresses. Experimental. Described in RFC 1183.

    The following classes of resource records are currently valid in the DNS:

    IN

    The Internet.

    CH

    Chaosnet, a LAN protocol created at MIT in the mid-1970s. Rarely used for its historical purpose, but reused for BIND's built-in server information zones, e.g., version.bind.

    HS

    Hesiod, an information service developed by MIT's Project Athena. It is used to share information about various systems databases, such as users, groups, printers and so on.

    The owner name is often implicit, rather than forming an integral part of the RR. For example, many name servers internally form tree or hash structures for the name space, and chain RRs off nodes. The remaining RR parts are the fixed header (type, class, TTL) which is consistent for all RRs, and a variable part (RDATA) that fits the needs of the resource being described.

    The meaning of the TTL field is a time limit on how long an RR can be kept in a cache. This limit does not apply to authoritative data in zones; it is also timed out, but by the refreshing policies for the zone. The TTL is assigned by the administrator for the zone where the data originates. While short TTLs can be used to minimize caching, and a zero TTL prohibits caching, the realities of Internet performance suggest that these times should be on the order of days for the typical host. If a change can be anticipated, the TTL can be reduced prior to the change to minimize inconsistency during the change, and then increased back to its former value following the change.

    The data in the RDATA section of RRs is carried as a combination of binary strings and domain names. The domain names are frequently used as "pointers" to other data in the DNS.

    Textual expression of RRs

    RRs are represented in binary form in the packets of the DNS protocol, and are usually represented in highly encoded form when stored in a name server or resolver. In the examples provided in RFC 1034, a style similar to that used in master files was employed in order to show the contents of RRs. In this format, most RRs are shown on a single line, although continuation lines are possible using parentheses.

    The start of the line gives the owner of the RR. If a line begins with a blank, then the owner is assumed to be the same as that of the previous RR. Blank lines are often included for readability.

    Following the owner, we list the TTL, type, and class of the RR. Class and type use the mnemonics defined above, and TTL is an integer before the type field. In order to avoid ambiguity in parsing, type and class mnemonics are disjoint, TTLs are integers, and the type mnemonic is always last. The IN class and TTL values are often omitted from examples in the interests of clarity.

    The resource data or RDATA section of the RR are given using knowledge of the typical representation for the data.

    For example, we might show the RRs carried in a message as:

    ISI.EDU.

    MX

    10 VENERA.ISI.EDU.

    MX

    10 VAXA.ISI.EDU

    VENERA.ISI.EDU

    A

    128.9.0.32

    A

    10.1.0.52

    VAXA.ISI.EDU

    A

    10.2.0.27

    A

    128.9.0.33

    The MX RRs have an RDATA section which consists of a 16-bit number followed by a domain name. The address RRs use a standard IP address format to contain a 32-bit internet address.

    The above example shows six RRs, with two RRs at each of three domain names.

    Similarly we might see:

    XX.LCS.MIT.EDU.

    IN A

    10.0.0.44

     

    CH A

    MIT.EDU. 2420

    This example shows two addresses for XX.LCS.MIT.EDU, each of a different class.

    Discussion of MX Records

    As described above, domain servers store information as a series of resource records, each of which contains a particular piece of information about a given domain name (which is usually, but not always, a host). The simplest way to think of a RR is as a typed pair of data, a domain name matched with a relevant datum, and stored with some additional type information to help systems determine when the RR is relevant.

    MX records are used to control delivery of email. The data specified in the record is a priority and a domain name. The priority controls the order in which email delivery is attempted, with the lowest number first. If two priorities are the same, a server is chosen randomly. If no servers at a given priority are responding, the mail transport agent will fall back to the next largest priority. Priority numbers do not have any absolute meaning — they are relevant only respective to other MX records for that domain name. The domain name given is the machine to which the mail will be delivered. It must have an associated address record (A or AAAA) — CNAME is not sufficient.

    For a given domain, if there is both a CNAME record and an MX record, the MX record is in error, and will be ignored. Instead, the mail will be delivered to the server specified in the MX record pointed to by the CNAME. For example:

    example.com.

    IN

    MX

    10

    mail.example.com.

    IN

    MX

    10

    mail2.example.com.

    IN

    MX

    20

    mail.backup.org.

    mail.example.com.

    IN

    A

    10.0.0.1

    mail2.example.com.

    IN

    A

    10.0.0.2

    Mail delivery will be attempted to mail.example.com and mail2.example.com (in any order), and if neither of those succeed, delivery to mail.backup.org will be attempted.

    Setting TTLs

    The time-to-live of the RR field is a 32-bit integer represented in units of seconds, and is primarily used by resolvers when they cache RRs. The TTL describes how long a RR can be cached before it should be discarded. The following three types of TTL are currently used in a zone file.

    SOA

    The last field in the SOA is the negative caching TTL. This controls how long other servers will cache no-such-domain (NXDOMAIN) responses from you.

    The maximum time for negative caching is 3 hours (3h).

    $TTL

    The $TTL directive at the top of the zone file (before the SOA) gives a default TTL for every RR without a specific TTL set.

    RR TTLs

    Each RR can have a TTL as the second field in the RR, which will control how long other servers can cache the it.

    All of these TTLs default to units of seconds, though units can be explicitly specified, for example, 1h30m.

    Inverse Mapping in IPv4

    Reverse name resolution (that is, translation from IP address to name) is achieved by means of the in-addr.arpa domain and PTR records. Entries in the in-addr.arpa domain are made in least-to-most significant order, read left to right. This is the opposite order to the way IP addresses are usually written. Thus, a machine with an IP address of 10.1.2.3 would have a corresponding in-addr.arpa name of 3.2.1.10.in-addr.arpa. This name should have a PTR resource record whose data field is the name of the machine or, optionally, multiple PTR records if the machine has more than one name. For example, in the [example.com] domain:

    $ORIGIN

    2.1.10.in-addr.arpa

    3

    IN PTR foo.example.com.

    Note

    The $ORIGIN lines in the examples are for providing context to the examples only — they do not necessarily appear in the actual usage. They are only used here to indicate that the example is relative to the listed origin.

    Other Zone File Directives

    The Master File Format was initially defined in RFC 1035 and has subsequently been extended. While the Master File Format itself is class independent all records in a Master File must be of the same class.

    Master File Directives include $ORIGIN, $INCLUDE, and $TTL.

    The @ (at-sign)

    When used in the label (or name) field, the asperand or at-sign (@) symbol represents the current origin. At the start of the zone file, it is the <zone_name> (followed by trailing dot).

    The $ORIGIN Directive

    Syntax: $ORIGIN domain-name [comment]

    $ORIGIN sets the domain name that will be appended to any unqualified records. When a zone is first read in there is an implicit $ORIGIN <zone_name>. (followed by trailing dot). The current $ORIGIN is appended to the domain specified in the $ORIGIN argument if it is not absolute. 

    $ORIGIN example.com.
WWW     CNAME   MAIN-SERVER

    is equivalent to 

    WWW.EXAMPLE.COM. CNAME MAIN-SERVER.EXAMPLE.COM.

    The $INCLUDE Directive

    Syntax: $INCLUDE filename [ origin ] [ comment ]

    Read and process the file filename as if it were included into the file at this point. If origin is specified the file is processed with $ORIGIN set to that value, otherwise the current $ORIGIN is used.

    The origin and the current domain name revert to the values they had prior to the $INCLUDE once the file has been read.

    Note

    RFC 1035 specifies that the current origin should be restored after an $INCLUDE, but it is silent on whether the current domain name should also be restored. BIND 9 restores both of them. This could be construed as a deviation from RFC 1035, a feature, or both.

    The $TTL Directive

    Syntax: $TTL default-ttl [ comment ]

    Set the default Time To Live (TTL) for subsequent records with undefined TTLs. Valid TTLs are of the range 0-2147483647 seconds.

    $TTL is defined in RFC 2308.

    BIND Master File Extension: the $GENERATE Directive

    Syntax: $GENERATE range lhs [ttl] [class] type rhs [comment]

    $GENERATE is used to create a series of resource records that only differ from each other by an iterator. $GENERATE can be used to easily generate the sets of records required to support sub /24 reverse delegations described in RFC 2317: Classless IN-ADDR.ARPA delegation. 

    $ORIGIN 0.0.192.IN-ADDR.ARPA.
$GENERATE 1-2 0 NS SERVER$.EXAMPLE.
$GENERATE 1-127 $ CNAME $.0

    is equivalent to 

    0.0.0.192.IN-ADDR.ARPA. NS SERVER1.EXAMPLE.
0.0.0.192.IN-ADDR.ARPA. NS SERVER2.EXAMPLE.
1.0.0.192.IN-ADDR.ARPA. CNAME 1.0.0.0.192.IN-ADDR.ARPA.
2.0.0.192.IN-ADDR.ARPA. CNAME 2.0.0.0.192.IN-ADDR.ARPA.
...
127.0.0.192.IN-ADDR.ARPA. CNAME 127.0.0.0.192.IN-ADDR.ARPA.

    range

    This can be one of two forms: start-stop or start-stop/step. If the first form is used, then step is set to 1. All of start, stop and step must be positive.

    lhs

    This describes the owner name of the resource records to be created. Any single $ (dollar sign) symbols within the lhs string are replaced by the iterator value. To get a $ in the output, you need to escape the $ using a backslash \, e.g. \$. The $ may optionally be followed by modifiers which change the offset from the iterator, field width and base. Modifiers are introduced by a { (left brace) immediately following the $ as ${offset[,width[,base]]}. For example, ${-20,3,d} subtracts 20 from the current value, prints the result as a decimal in a zero-padded field of width 3. Available output forms are decimal (d), octal (o) and hexadecimal (x or X for uppercase). The default modifier is ${0,0,d}. If the lhs is not absolute, the current $ORIGIN is appended to the name.

    For compatibility with earlier versions, $$ is still recognized as indicating a literal $ in the output.

    ttl

    Specifies the time-to-live of the generated records. If not specified this will be inherited using the normal TTL inheritance rules.

    class and ttl can be entered in either order.

    class

    Specifies the class of the generated records. This must match the zone class if it is specified.

    class and ttl can be entered in either order.

    type

    At present the only supported types are PTR, CNAME, DNAME, A, AAAA and NS.

    rhs

    rhs is a domain name. It is processed similarly to lhs.

    The $GENERATE directive is a BIND extension and not part of the standard zone file format.

    BIND 8 does not support the optional TTL and CLASS fields.

    Additional File Formats

    In addition to the standard textual format, BIND 9 supports the ability to read or dump to zone files in other formats. The raw format is currently available as an additional format. It is a binary format representing BIND 9's internal data structure directly, thereby remarkably improving the loading time.

    For a primary server, a zone file in the raw format is expected to be generated from a textual zone file by the named-compilezone command. For a secondary server or for a dynamic zone, it is automatically generated (if this format is specified by the masterfile-format option) when named dumps the zone contents after zone transfer or when applying prior updates.

    If a zone file in a binary format needs manual modification, it first must be converted to a textual form by the named-compilezone command. All necessary modification should go to the text file, which should then be converted to the binary form by the named-compilezone command again.

    Although the raw format uses the network byte order and avoids architecture-dependent data alignment so that it is as much portable as possible, it is primarily expected to be used inside the same single system. In order to export a zone file in the raw format or make a portable backup of the file, it is recommended to convert the file to the standard textual representation.

    BIND9 Statistics

    BIND 9 maintains lots of statistics information and provides several interfaces for users to get access to the statistics. The available statistics include all statistics counters that were available in BIND 8 and are meaningful in BIND 9, and other information that is considered useful.

    The statistics information is categorized into the following sections.

    Incoming Requests

    The number of incoming DNS requests for each OPCODE.

    Incoming Queries

    The number of incoming queries for each RR type.

    Outgoing Queries

    The number of outgoing queries for each RR type sent from the internal resolver. Maintained per view.

    Name Server Statistics

    Statistics counters about incoming request processing.

    Zone Maintenance Statistics

    Statistics counters regarding zone maintenance operations such as zone transfers.

    Resolver Statistics

    Statistics counters about name resolution performed in the internal resolver. Maintained per view.

    Cache DB RRsets

    The number of RRsets per RR type (positive or negative) and nonexistent names stored in the cache database. Maintained per view.

    Socket I/O Statistics

    Statistics counters about network related events.

    A subset of Name Server Statistics is collected and shown per zone for which the server has the authority when zone-statistics is set to yes. These statistics counters are shown with their zone and view names. In some cases the view names are omitted for the default view.

    There are currently two user interfaces to get access to the statistics. One is in the plain text format dumped to the file specified by the statistics-file configuration option. The other is remotely accessible via a statistics channel when the statistics-channels statement is specified in the configuration file (see the section called “statistics-channels Statement Grammar”.)

    The Statistics File

    The text format statistics dump begins with a line, like:

    +++ Statistics Dump +++ (973798949)

    The number in parentheses is a standard Unix-style timestamp, measured as seconds since January 1, 1970. Following that line is a set of statistics information, which is categorized as described above. Each section begins with a line, like:

    ++ Name Server Statistics ++

    Each section consists of lines, each containing the statistics counter value followed by its textual description. See below for available counters. For brevity, counters that have a value of 0 are not shown in the statistics file.

    The statistics dump ends with the line where the number is identical to the number in the beginning line; for example:

    --- Statistics Dump --- (973798949)

    Statistics Counters

    The following tables summarize statistics counters that BIND 9 provides. For each row of the tables, the leftmost column is the abbreviated symbol name of that counter. These symbols are shown in the statistics information accessed via an HTTP statistics channel. The rightmost column gives the description of the counter, which is also shown in the statistics file (but, in this document, possibly with slight modification for better readability). Additional notes may also be provided in this column. When a middle column exists between these two columns, it gives the corresponding counter name of the BIND 8 statistics, if applicable.

    QryDuplicate

    RDupQ

    Queries which the server attempted to recurse but discovered an existing query with the same IP address, port, query ID, name, type and class already being processed. This corresponds to the duplicate counter of previous versions of BIND 9.

    QryDropped

    Recursive queries for which the server discovered an excessive number of existing recursive queries for the same name, type and class and were subsequently dropped. This is the number of dropped queries due to the reason explained with the clients-per-query and max-clients-per-query options (see the description about clients-per-query.) This corresponds to the dropped counter of previous versions of BIND 9.

    QryFailure

    Other query failures. This corresponds to the failure counter of previous versions of BIND 9. Note: this counter is provided mainly for backward compatibility with the previous versions. Normally a more fine-grained counters such as AuthQryRej and RecQryRej that would also fall into this counter are provided, and so this counter would not be of much interest in practice.

    Socket I/O Statistics Counters

    Socket I/O statistics counters are defined per socket types, which are UDP4 (UDP/IPv4), UDP6 (UDP/IPv6), TCP4 (TCP/IPv4), TCP6 (TCP/IPv6), Unix (Unix Domain), and FDwatch (sockets opened outside the socket module). In the following table <TYPE> represents a socket type. Not all counters are available for all socket types; exceptions are noted in the description field.

    Symbol

    Description

    <TYPE>Open

    Sockets opened successfully. This counter is not applicable to the FDwatch type.

    <TYPE>OpenFail

    Failures of opening sockets. This counter is not applicable to the FDwatch type.

    Compatibility with BIND 8 Counters

    Most statistics counters that were available in BIND 8 are also supported in BIND 9 as shown in the above tables. Here are notes about other counters that do not appear in these tables.

    RFwdR,SFwdR

    These counters are not supported because BIND 9 does not adopt the notion of forwarding as BIND 8 did.

    RAXFR

    This counter is accessible in the Incoming Queries section.

    RIQ

    This counter is accessible in the Incoming Requests section.

    ROpts

    This counter is not supported because BIND 9 does not care about IP options in the first place.

    Access Control Lists

    Access Control Lists (ACLs) are address match lists that you can set up and nickname for future use in allow-notify, allow-query, allow-query-on, allow-recursion, allow-recursion-on, blackhole, allow-transfer, etc.

    Using ACLs allows you to have finer control over who can access your name server, without cluttering up your config files with huge lists of IP addresses.

    It is a good idea to use ACLs, and to control access to your server. Limiting access to your server by outside parties can help prevent spoofing and denial of service (DoS) attacks against your server.

    Here is an example of how to properly apply ACLs: 

    // Set up an ACL named "bogusnets" that will block RFC1918 space
// and some reserved space, which is commonly used in spoofing attacks.
acl bogusnets {
        0.0.0.0/8;  192.0.2.0/24; 224.0.0.0/3;
        10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16;
};

// Set up an ACL called our-nets. Replace this with the real IP numbers.
acl our-nets { x.x.x.x/24; x.x.x.x/21; };
options {
  ...
  ...
  allow-query { our-nets; };
  allow-recursion { our-nets; };
  ...
  blackhole { bogusnets; };
  ...
};

zone "example.com" {
  type master;
  file "m/example.com";
  allow-query { any; };
};

    This allows recursive queries of the server from the outside unless recursion has been previously disabled.

    For more information on how to use ACLs to protect your server, see the AUSCERT advisory at:

    ftp://ftp.auscert.org.au/pub/auscert/advisory/AL-1999.004.dns_dos

    Chroot and Setuid

    On UNIX servers, it is possible to run BIND in a chrooted environment (using the chroot() function) by specifying the "-t" option for named. This can help improve system security by placing BIND in a "sandbox", which will limit the damage done if a server is compromised.

    Another useful feature in the UNIX version of BIND is the ability to run the daemon as an unprivileged user ( -u user ). We suggest running as an unprivileged user when using the chroot feature.

    Here is an example command line to load BIND in a chroot sandbox, /var/named, and to run named setuid to user 202:

    /usr/local/sbin/named -u 202 -t /var/named

    The chroot Environment

    In order for a chroot environment to work properly in a particular directory (for example, /var/named), you will need to set up an environment that includes everything BIND needs to run. From BIND's point of view, /var/named is the root of the filesystem. You will need to adjust the values of options like like directory and pid-file to account for this.

    Unlike with earlier versions of BIND, you typically will not need to compile named statically nor install shared libraries under the new root. However, depending on your operating system, you may need to set up things like /dev/zero, /dev/random, /dev/log, and /etc/localtime.

    Using the setuid Function

    Prior to running the named daemon, use the touch utility (to change file access and modification times) or the chown utility (to set the user id and/or group id) on files to which you want BIND to write.

    Note

    Note that if the named daemon is running as an unprivileged user, it will not be able to bind to new restricted ports if the server is reloaded.

    Dynamic Update Security

    Access to the dynamic update facility should be strictly limited. In earlier versions of BIND, the only way to do this was based on the IP address of the host requesting the update, by listing an IP address or network prefix in the allow-update zone option. This method is insecure since the source address of the update UDP packet is easily forged. Also note that if the IP addresses allowed by the allow-update option include the address of a slave server which performs forwarding of dynamic updates, the master can be trivially attacked by sending the update to the slave, which will forward it to the master with its own source IP address causing the master to approve it without question.

    For these reasons, we strongly recommend that updates be cryptographically authenticated by means of transaction signatures (TSIG). That is, the allow-update option should list only TSIG key names, not IP addresses or network prefixes. Alternatively, the new update-policy option can be used.

    Some sites choose to keep all dynamically-updated DNS data in a subdomain and delegate that subdomain to a separate zone. This way, the top-level zone containing critical data such as the IP addresses of public web and mail servers need not allow dynamic update at all.

    Common Problems

    It's not working; how can I figure out what's wrong?

    The best solution to solving installation and configuration issues is to take preventative measures by setting up logging files beforehand. The log files provide a source of hints and information that can be used to figure out what went wrong and how to fix the problem.

    Incrementing and Changing the Serial Number

    Zone serial numbers are just numbers — they aren't date related. A lot of people set them to a number that represents a date, usually of the form YYYYMMDDRR. Occasionally they will make a mistake and set them to a "date in the future" then try to correct them by setting them to the "current date". This causes problems because serial numbers are used to indicate that a zone has been updated. If the serial number on the slave server is lower than the serial number on the master, the slave server will attempt to update its copy of the zone.

    Setting the serial number to a lower number on the master server than the slave server means that the slave will not perform updates to its copy of the zone.

    The solution to this is to add 2147483647 (2^31-1) to the number, reload the zone and make sure all slaves have updated to the new zone serial number, then reset the number to what you want it to be, and reload the zone again.

    Where Can I Get Help?

    The Internet Systems Consortium (ISC) offers a wide range of support and service agreements for BIND and DHCP servers. Four levels of premium support are available and each level includes support for all ISC programs, significant discounts on products and training, and a recognized priority on bug fixes and non-funded feature requests. In addition, ISC offers a standard support agreement package which includes services ranging from bug fix announcements to remote support. It also includes training in BIND and DHCP.

    To discuss arrangements for support, contact info@isc.org or visit the ISC web page at http://www.isc.org/services/support/ to read more.

    A Brief History of the DNS and BIND

    Although the "official" beginning of the Domain Name System occurred in 1984 with the publication of RFC 920, the core of the new system was described in 1983 in RFCs 882 and 883. From 1984 to 1987, the ARPAnet (the precursor to today's Internet) became a testbed of experimentation for developing the new naming/addressing scheme in a rapidly expanding, operational network environment. New RFCs were written and published in 1987 that modified the original documents to incorporate improvements based on the working model. RFC 1034, "Domain Names-Concepts and Facilities", and RFC 1035, "Domain Names-Implementation and Specification" were published and became the standards upon which all DNS implementations are built.

    The first working domain name server, called "Jeeves", was written in 1983-84 by Paul Mockapetris for operation on DEC Tops-20 machines located at the University of Southern California's Information Sciences Institute (USC-ISI) and SRI International's Network Information Center (SRI-NIC). A DNS server for Unix machines, the Berkeley Internet Name Domain (BIND) package, was written soon after by a group of graduate students at the University of California at Berkeley under a grant from the US Defense Advanced Research Projects Administration (DARPA).

    Versions of BIND through 4.8.3 were maintained by the Computer Systems Research Group (CSRG) at UC Berkeley. Douglas Terry, Mark Painter, David Riggle and Songnian Zhou made up the initial BIND project team. After that, additional work on the software package was done by Ralph Campbell. Kevin Dunlap, a Digital Equipment Corporation employee on loan to the CSRG, worked on BIND for 2 years, from 1985 to 1987. Many other people also contributed to BIND development during that time: Doug Kingston, Craig Partridge, Smoot Carl-Mitchell, Mike Muuss, Jim Bloom and Mike Schwartz. BIND maintenance was subsequently handled by Mike Karels and Øivind Kure.

    BIND versions 4.9 and 4.9.1 were released by Digital Equipment Corporation (now Compaq Computer Corporation). Paul Vixie, then a DEC employee, became BIND's primary caretaker. He was assisted by Phil Almquist, Robert Elz, Alan Barrett, Paul Albitz, Bryan Beecher, Andrew Partan, Andy Cherenson, Tom Limoncelli, Berthold Paffrath, Fuat Baran, Anant Kumar, Art Harkin, Win Treese, Don Lewis, Christophe Wolfhugel, and others.

    In 1994, BIND version 4.9.2 was sponsored by Vixie Enterprises. Paul Vixie became BIND's principal architect/programmer.

    BIND versions from 4.9.3 onward have been developed and maintained by the Internet Systems Consortium and its predecessor, the Internet Software Consortium, with support being provided by ISC's sponsors.

    As co-architects/programmers, Bob Halley and Paul Vixie released the first production-ready version of BIND version 8 in May 1997.

    BIND version 9 was released in September 2000 and is a major rewrite of nearly all aspects of the underlying BIND architecture.

    BIND versions 4 and 8 are officially deprecated. No additional development is done on BIND version 4 or BIND version 8.

    BIND development work is made possible today by the sponsorship of several corporations, and by the tireless work efforts of numerous individuals.

    General DNS Reference Information

    IPv6 addresses (AAAA)

    IPv6 addresses are 128-bit identifiers for interfaces and sets of interfaces which were introduced in the DNS to facilitate scalable Internet routing. There are three types of addresses: Unicast, an identifier for a single interface; Anycast, an identifier for a set of interfaces; and Multicast, an identifier for a set of interfaces. Here we describe the global Unicast address scheme. For more information, see RFC 3587, "Global Unicast Address Format."

    IPv6 unicast addresses consist of a global routing prefix, a subnet identifier, and an interface identifier.

    The global routing prefix is provided by the upstream provider or ISP, and (roughly) corresponds to the IPv4 network section of the address range. The subnet identifier is for local subnetting, much the same as subnetting an IPv4 /16 network into /24 subnets. The interface identifier is the address of an individual interface on a given network; in IPv6, addresses belong to interfaces rather than to machines.

    The subnetting capability of IPv6 is much more flexible than that of IPv4: subnetting can be carried out on bit boundaries, in much the same way as Classless InterDomain Routing (CIDR), and the DNS PTR representation ("nibble" format) makes setting up reverse zones easier.

    The Interface Identifier must be unique on the local link, and is usually generated automatically by the IPv6 implementation, although it is usually possible to override the default setting if necessary. A typical IPv6 address might look like: 2001:db8:201:9:a00:20ff:fe81:2b32

    IPv6 address specifications often contain long strings of zeros, so the architects have included a shorthand for specifying them. The double colon (`::') indicates the longest possible string of zeros that can fit, and can be used only once in an address.

    Internet Drafts

    Internet Drafts (IDs) are rough-draft working documents of the Internet Engineering Task Force. They are, in essence, RFCs in the preliminary stages of development. Implementors are cautioned not to regard IDs as archival, and they should not be quoted or cited in any formal documents unless accompanied by the disclaimer that they are "works in progress." IDs have a lifespan of six months after which they are deleted unless updated by their authors.

("ISC") Copyright (C) 2000, 2001 Internet Software Consortium. See COPYRIGHT in the source root or http://isc.org/copyright.html for terms. The BIND v9 ARM master document is now kept in DocBook XML format. Version: $Id: README-SGML,v 1.17 2004/03/05 05:04:43 marka Exp $ The entire ARM is in the single file: Bv9ARM-book.xml All of the other documents - HTML, PDF, etc - are generated from this master source. This file attempts to describe what tools are necessary for the maintenance of this document as well as the generation of the alternate formats of this document. This file will also spend a very little time describing the XML and SGML headers so you can understand a bit what you may need to do to be able to work with this document in any fashion other than simply editing it. We will spend almost no time on the actual tags and how to write an XML DocBook compliant document. If you are at all familiar with SGML or HTML it will be very evident. You only need to know what the tags are and how to use them. You can find a good resource either for this either online or in printed form: DocBook: The Definitive Guide By Norman Walsh and Leonard Muellner ISBN: 156592-580-7 1st Edition, October 1999 Copyright (C) 1999 by O'Reilly & Associates, Inc. All rights reserved. The book is available online in HTML format: http://docbook.org/ and buried in: http://www.nwalsh.com/docbook/defguide/index.html A lot of useful stuff is at NWalsh's site in general. You may also want to look at: http://www.xml.com/ The BIND v9 ARM is based on the XML 4.0 DocBook DTD. Every XML and SGML document begins with a prefix that tells where to find the file that describes the meaning and structure of the tags used in the rest of the document. For our XML DocBook 4.0 based document this prefix looks like this: This "DOCTYPE" statement has three parts, of which we are only using two: o The highest level term that represents this document (in this case it is "book" o The identifier that tells us which DTD to use. This identifier has two parts, the "Formal Public Identifier" (or FPI) and the system identifier. In SGML you can have either a FPI or a SYSTEM identifier but you have to have at least one of them. In XML you have to have a SYSTEM identifier. FP & SYSTEM identifiers - These are names/lookups for the actual DTD. The FPI is a globally unique name that should, on a properly configured system, tell you exactly what DTD to use. The SYSTEM identifier gives an absolute location for the DTD. In XML these are supposed to be properly formatted URL's. SGML has these things called "catalogs" that are files that map FPI's in to actual files. A "catalog" can also be used to remap a SYSTEM identifier so you can say something like: "http://www.oasis.org/foo" is actually "/usr/local/share/xml/foo.dtd" When you use various SGML/XML tools they need to be configured to look at the same "catalog" files so that as you move from tool to tool they all refer to the same DTD for the same document. We will be spending most of our configuration time making sure our tools use the same "catalog" files and that we have the same DTD's installed on our machines. XML's requirement of the SYSTEM identifier over the FPI will probably lead to more problems as it does not guarantee that everyone is using the same DTD. I did my initial work with the "sgmltools" the XML 4.0 DocBook DTD and "jade" or "openjade." You can get the 4.0 XML DocBook DTD from: http://www.docbook.org/xml/4.0/ (download the .zip file.) NOTE: We will eventually be changing the SYSTEM identifier to the recommended value of: http://www.oasis-open.org/docbook/xml/4.0/docbookx.dtd NOTE: Under FreeBSD this is the package: /usr/ports/textproc/docbook-xml NetBSD instructions are coming soon. With packages listed below installed under FreeBSD the "catalog" file that all the tools refer to at least one is in: /usr/local/share/sgml/catalog In order for our SYSTEM identifier for the XML DocBook dtd to be found I create a new catalog file at the top of the XML directory created on FreeBSD: /usr/local/share/xml/catalog This file has one line: SYSTEM "http://www.oasis-open.org/docbook/xml/4.0/docbookx.dtd" "/usr/local/share/xml/dtd/docbook/docbookx.dtd" Then in the main "catalog" I have it include this XML catalog: CATALOG "/usr/local/share/xml/catalog" On your systems you need to replace "/usr/local/share" with your prefix root (probably /usr/pkg under NetBSD.) NOTE: The URL used above is supposed to the be the proper one for this XML DocBook DTD... but there is nothing at that URL so you really do need the "SYSTEM" identifier mapping in your catalog (or make the SYSTEM identifier in your document refer to the real location of the file on your local system.) HOW TO VALIDATE A DOCUMENT: I use the sgmltools "nsgmls" document validator. Since we are using XML we need to use the XML declarations, which are installed as part of the modular DSSL style sheets: nsgmls -sv /usr/local/share/sgml/docbook/dsssl/modular/dtds/decls/xml.dcl \ Bv9ARM-book.xml A convenient shell script "validate.sh" is now generated by configure to invoke the above command with the correct system-dependent paths. The SGML tools can be found at: ftp://ftp.us.sgmltools.org/pub/SGMLtools/v2.0/source/ \ ftp://ftp.nllgg.nl/pub/SGMLtools/v2.0/source/ FreeBSD package for these is: /usr/ports/textproc/sgmltools HOW TO RENDER A DOCUMENT AS HTML or TeX: o Generate html doc with: openjade -v -d ./nominum-docbook-html.dsl \ -t sgml \ /usr/local/share/sgml/docbook/dsssl/modular/dtds/decls/xml.dcl \ Bv9ARM-book.xml A convenient shell script "genhtml.sh" is now generated by configure to invoke the above command with the correct system-dependent paths. On NetBSD there is no port for "openjade" however "jade" does still work. However you need to specify the "catalog" file to use for style sheets on the command line AND you need to have a default "catalog" mapping where to find various DTDs. It seems that "jade" installed out of the box on NetBSD does not use a globally defined "catalog" file for mapping PUBLIC identifiers in to SYSTEM identifiers. So you need to have a "catalog" file in your current working directory that has in it this: (these are probably more entries than you need!) CATALOG "/usr/pkg/share/sgml/iso8879/catalog" CATALOG "/usr/pkg/share/sgml/docbook/2.4.1/catalog" CATALOG "/usr/pkg/share/sgml/docbook/3.0/catalog" CATALOG "/usr/pkg/share/sgml/docbook/3.1/catalog" CATALOG "/usr/pkg/share/sgml/jade/catalog" CATALOG "/usr/local/share/xml/catalog" (These would all be "/usr/local" on FreeBSD) So the command for jade on NetBSD will look like this: jade -v -c /usr/pkg/share/sgml/catalog -t sgml \ -d ./nominum-docbook-html.dsl \ /usr/pkg/share/sgml/docbook/dsssl/modular/dtds/decls/xml.dcl \ ./Bv9ARM-book.xml Furthermore, since the style sheet subset we define has in it a hard coded path to the style sheet is based, it is actually generated by configure from a .in file so that it will contain the correct system-dependent path: where on FreeBSD the second line reads: On NetBSD it needs to read: NOTE: This is usually solved by having this style sheet modification be installed in a system directory and have it reference the style sheet it is based on via a relative path. o Generate TeX documentation: openjade -d ./nominum-docbook-print.dsl -t tex -v \ /usr/local/share/sgml/docbook/dsssl/modular/dtds/decls/xml.dcl \ Bv9ARM-book.xml If you have "jade" installed instead of "openjade" then use that as the command. There is little difference, openjade has some bug fixes and is in more active development. To convert the resulting TeX file in to a DVI file you need to do: tex "&jadetex" Bv9ARM-book.tex You can also directly generate the pdf file via: pdftex "&pdfjadetex" Bv9ARM-book.tex The scripts "genpdf.sh" and "gendvi." have been added to simply generating the PDF and DVI output. These substitute the correct paths of NetBSD & FreeBSD. You still need to have TeX, jadeTeX, and pdfTeX installed and configured properly for these to work. You will need to up both the "pool_size" and "hash_extra" variables in your texmf.cnf file and regenerate them. See below. You can see that I am using a DSSSL style sheet for DocBook. Actually two different ones - one for rendering html, and one for 'print' media. NOTE: For HTML we are using a Nominum DSSSL style instead of the default one (all it does is change the chunking to the chapter level and makes the files end with ".html" instead of ".htm" so far.) If you want to use the plain jane DSSSL style sheet replace the: -d ./nominum-docbook-html.dsl with -d /usr/local/share/sgml/docbook/dsssl/modular/html/docbook.dsl This style sheet will attempt to reference the one above. I am currently working on fixing these up so that it works the same on our various systems. The main trick is knowing which DTD's and DSSSL stylesheets you have installed, installing the right ones, and configuring a CATALOG that refers to them in the same way. We will probably end up putting our CATALOG's in the same place and then we should be able to generate and validate our documents with a minimal number of command line arguments. When running these commands you will get a lot of messages about a bunch of general entities not being defined and having no default entity. You can ignore those for now. Also with the style sheets we have and jade as it is you will get messages about "xref to title" being unsupported. You can ignore these for now as well. === Getting the various tools installed on FreeBSD (NetBSD coming soon..) o On freebsd you need to install the following packages: o print/teTeX o textproc/openjade o textproc/docbook o textproc/docbook-xml o textproc/dsssl-docbook-modular o textproc/dtd-catalogs o on freebsd you need to make some entities visible to the docbook xml dtd by making a symlink (can probably be done with a catalog too) ln -s /usr/local/share/xml/entity /usr/local/share/xml/dtd/docbook/ent o you may need to edit /usr/local/share/sgml/catalog and add the line: CATALOG "/usr/local/share/sgml/openjade/catalog" o add "hugelatex," Enlarge pool sizes, install the jadetex TeX driver file. cd /usr/local/share/texmf/web2c/ sudo cp texmf.cnf texmf.cnf.bak o edit the lines in texmf.cnf with these keys to these values: main_memory = 1100000 hash_extra = 15000 pool_size = 500000 string_vacancies = 45000 max_strings = 55000 pool_free = 47500 nest_size = 500 param_size = 1500 save_size = 5000 stack_size = 1500 sudo tex -ini -progname=hugelatex -fmt=hugelatex latex.ltx sudo texconfig init sudo texhash o For the jadetex macros you will need I recommend you get a more current version than what is packaged with openjade or jade. Checkout http://www.tug.org/applications/jadetex/ Unzip the file you get from there (should be jadetex-2.20 or newer.) In the directory you unzip: sudo make install sudo texhash NOTE: In the most uptodate "ports" for FreeBSD, jadetext is 2.20+ so on this platform you should be set as of 2001.01.08. bind-9.6-ESV-R6/doc/arm/isc-logo.eps000644 024064 023255 00001770215 11734112744 017112 0ustar00eachsweng000000 000000 %!PS-Adobe-3.1 EPSF-3.0 %ADO_DSC_Encoding: MacOS Roman %%Title: ISC_logo_only_RGB.eps %%Creator: Adobe Illustrator(R) 13.0 %%For: Brian Reid %%CreationDate: 3/25/10 %%BoundingBox: 0 0 118 46 %%HiResBoundingBox: 0 0 117.9991 45.0176 %%CropBox: 0 0 117.9991 45.0176 %%LanguageLevel: 2 %%DocumentData: Clean7Bit %ADOBeginClientInjection: DocumentHeader "AI11EPS" %%AI8_CreatorVersion: 13.0.2 %AI9_PrintingDataBegin %ADO_BuildNumber: Adobe Illustrator(R) 13.0.2 x434 R agm 4.4379 ct 5.1039 %ADO_ContainsXMP: MainFirst %ADOEndClientInjection: DocumentHeader "AI11EPS" %%Pages: 1 %%DocumentNeededResources: %%DocumentSuppliedResources: procset Adobe_AGM_Image 1.0 0 %%+ procset Adobe_CoolType_Utility_T42 1.0 0 %%+ procset Adobe_CoolType_Utility_MAKEOCF 1.23 0 %%+ procset Adobe_CoolType_Core 2.31 0 %%+ procset Adobe_AGM_Core 2.0 0 %%+ procset Adobe_AGM_Utils 1.0 0 %%DocumentFonts: %%DocumentNeededFonts: %%DocumentNeededFeatures: %%DocumentSuppliedFeatures: %%DocumentCustomColors: %%CMYKCustomColor: %%RGBCustomColor: %%EndComments %%BeginDefaults %%ViewingOrientation: 1 0 0 1 %%EndDefaults %%BeginProlog %%BeginResource: procset Adobe_AGM_Utils 1.0 0 %%Version: 1.0 0 %%Copyright: Copyright(C)2000-2006 Adobe Systems, Inc.

    Name

    dig — DNS lookup utility

    Synopsis

    dig [@server] [-b address] [-c class] [-f filename] [-k filename] [-m] [-p port#] [-q name] [-t type] [-x addr] [-y [hmac:]name:key] [-4] [-6] [name] [type] [class] [queryopt...]

    dig [-h]

    dig [global-queryopt...] [query...]

    DESCRIPTION

    dig (domain information groper) is a flexible tool for interrogating DNS name servers. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use dig to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than dig.

    Although dig is normally used with command-line arguments, it also has a batch mode of operation for reading lookup requests from a file. A brief summary of its command-line arguments and options is printed when the -h option is given. Unlike earlier versions, the BIND 9 implementation of dig allows multiple lookups to be issued from the command line.

    Unless it is told to query a specific name server, dig will try each of the servers listed in /etc/resolv.conf.

    When no command line arguments or options are given, dig will perform an NS query for "." (the root).

    It is possible to set per-user defaults for dig via ${HOME}/.digrc. This file is read and any options in it are applied before the command line arguments.

    The IN and CH class names overlap with the IN and CH top level domains names. Either use the -t and -c options to specify the type and class, use the -q the specify the domain name, or use "IN." and "CH." when looking up these top level domains.

    SIMPLE USAGE

    A typical invocation of dig looks like: 

     dig @server name type

    where:

    server

    is the name or IP address of the name server to query. This can be an IPv4 address in dotted-decimal notation or an IPv6 address in colon-delimited notation. When the supplied server argument is a hostname, dig resolves that name before querying that name server. If no server argument is provided, dig consults /etc/resolv.conf and queries the name servers listed there. The reply from the name server that responds is displayed.

    name

    is the name of the resource record that is to be looked up.

    type

    indicates what type of query is required — ANY, A, MX, SIG, etc. type can be any valid query type. If no type argument is supplied, dig will perform a lookup for an A record.

    OPTIONS

    The -b option sets the source IP address of the query to address. This must be a valid address on one of the host's network interfaces or "0.0.0.0" or "::". An optional port may be specified by appending "#<port>"

    The default query class (IN for internet) is overridden by the -c option. class is any valid class, such as HS for Hesiod records or CH for Chaosnet records.

    The -f option makes dig operate in batch mode by reading a list of lookup requests to process from the file filename. The file contains a number of queries, one per line. Each entry in the file should be organized in the same way they would be presented as queries to dig using the command-line interface.

    The -m option enables memory usage debugging.

    If a non-standard port number is to be queried, the -p option is used. port# is the port number that dig will send its queries instead of the standard DNS port number 53. This option would be used to test a name server that has been configured to listen for queries on a non-standard port number.

    The -4 option forces dig to only use IPv4 query transport. The -6 option forces dig to only use IPv6 query transport.

    The -t option sets the query type to type. It can be any valid query type which is supported in BIND 9. The default query type is "A", unless the -x option is supplied to indicate a reverse lookup. A zone transfer can be requested by specifying a type of AXFR. When an incremental zone transfer (IXFR) is required, type is set to ixfr=N. The incremental zone transfer will contain the changes made to the zone since the serial number in the zone's SOA record was N.

    The -q option sets the query name to name. This useful do distinguish the name from other arguments.

    Reverse lookups — mapping addresses to names — are simplified by the -x option. addr is an IPv4 address in dotted-decimal notation, or a colon-delimited IPv6 address. When this option is used, there is no need to provide the name, class and type arguments. dig automatically performs a lookup for a name like 11.12.13.10.in-addr.arpa and sets the query type and class to PTR and IN respectively. By default, IPv6 addresses are looked up using nibble format under the IP6.ARPA domain. To use the older RFC1886 method using the IP6.INT domain specify the -i option. Bit string labels (RFC2874) are now experimental and are not attempted.

    To sign the DNS queries sent by dig and their responses using transaction signatures (TSIG), specify a TSIG key file using the -k option. You can also specify the TSIG key itself on the command line using the -y option; hmac is the type of the TSIG, default HMAC-MD5, name is the name of the TSIG key and key is the actual key. The key is a base-64 encoded string, typically generated by dnssec-keygen(8). Caution should be taken when using the -y option on multi-user systems as the key can be visible in the output from ps(1) or in the shell's history file. When using TSIG authentication with dig, the name server that is queried needs to know the key and algorithm that is being used. In BIND, this is done by providing appropriate key and server statements in named.conf.

    QUERY OPTIONS

    dig provides a number of query options which affect the way in which lookups are made and the results displayed. Some of these set or reset flag bits in the query header, some determine which sections of the answer get printed, and others determine the timeout and retry strategies.

    Each query option is identified by a keyword preceded by a plus sign (+). Some keywords set or reset an option. These may be preceded by the string no to negate the meaning of that keyword. Other keywords assign values to options like the timeout interval. They have the form +keyword=value. The query options are:

    +[no]tcp

    Use [do not use] TCP when querying name servers. The default behavior is to use UDP unless an AXFR or IXFR query is requested, in which case a TCP connection is used.

    +[no]vc

    Use [do not use] TCP when querying name servers. This alternate syntax to +[no]tcp is provided for backwards compatibility. The "vc" stands for "virtual circuit".

    +[no]ignore

    Ignore truncation in UDP responses instead of retrying with TCP. By default, TCP retries are performed.

    +domain=somename

    Set the search list to contain the single domain somename, as if specified in a domain directive in /etc/resolv.conf, and enable search list processing as if the +search option were given.

    +[no]search

    Use [do not use] the search list defined by the searchlist or domain directive in resolv.conf (if any). The search list is not used by default.

    +[no]showsearch

    Perform [do not perform] a search showing intermediate results.

    +[no]defname

    Deprecated, treated as a synonym for +[no]search

    +[no]aaonly

    Sets the "aa" flag in the query.

    +[no]aaflag

    A synonym for +[no]aaonly.

    +[no]adflag

    Set [do not set] the AD (authentic data) bit in the query. This requests the server to return whether all of the answer and authority sections have all been validated as secure according to the security policy of the server. AD=1 indicates that all records have been validated as secure and the answer is not from a OPT-OUT range. AD=0 indicate that some part of the answer was insecure or not validated.

    +[no]cdflag

    Set [do not set] the CD (checking disabled) bit in the query. This requests the server to not perform DNSSEC validation of responses.

    +[no]cl

    Display [do not display] the CLASS when printing the record.

    +[no]ttlid

    Display [do not display] the TTL when printing the record.

    +[no]recurse

    Toggle the setting of the RD (recursion desired) bit in the query. This bit is set by default, which means dig normally sends recursive queries. Recursion is automatically disabled when the +nssearch or +trace query options are used.

    +[no]nssearch

    When this option is set, dig attempts to find the authoritative name servers for the zone containing the name being looked up and display the SOA record that each name server has for the zone.

    +[no]trace

    Toggle tracing of the delegation path from the root name servers for the name being looked up. Tracing is disabled by default. When tracing is enabled, dig makes iterative queries to resolve the name being looked up. It will follow referrals from the root servers, showing the answer from each server that was used to resolve the lookup.

    +[no]cmd

    Toggles the printing of the initial comment in the output identifying the version of dig and the query options that have been applied. This comment is printed by default.

    +[no]short

    Provide a terse answer. The default is to print the answer in a verbose form.

    +[no]identify

    Show [or do not show] the IP address and port number that supplied the answer when the +short option is enabled. If short form answers are requested, the default is not to show the source address and port number of the server that provided the answer.

    +[no]comments

    Toggle the display of comment lines in the output. The default is to print comments.

    +[no]stats

    This query option toggles the printing of statistics: when the query was made, the size of the reply and so on. The default behavior is to print the query statistics.

    +[no]qr

    Print [do not print] the query as it is sent. By default, the query is not printed.

    +[no]question

    Print [do not print] the question section of a query when an answer is returned. The default is to print the question section as a comment.

    +[no]answer

    Display [do not display] the answer section of a reply. The default is to display it.

    +[no]authority

    Display [do not display] the authority section of a reply. The default is to display it.

    +[no]additional

    Display [do not display] the additional section of a reply. The default is to display it.

    +[no]all

    Set or clear all display flags.

    +time=T

    Sets the timeout for a query to T seconds. The default timeout is 5 seconds. An attempt to set T to less than 1 will result in a query timeout of 1 second being applied.

    +tries=T

    Sets the number of times to try UDP queries to server to T instead of the default, 3. If T is less than or equal to zero, the number of tries is silently rounded up to 1.

    +retry=T

    Sets the number of times to retry UDP queries to server to T instead of the default, 2. Unlike +tries, this does not include the initial query.

    +ndots=D

    Set the number of dots that have to appear in name to D for it to be considered absolute. The default value is that defined using the ndots statement in /etc/resolv.conf, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the search or domain directive in /etc/resolv.conf.

    +bufsize=B

    Set the UDP message buffer size advertised using EDNS0 to B bytes. The maximum and minimum sizes of this buffer are 65535 and 0 respectively. Values outside this range are rounded up or down appropriately. Values other than zero will cause a EDNS query to be sent.

    +edns=#

    Specify the EDNS version to query with. Valid values are 0 to 255. Setting the EDNS version will cause a EDNS query to be sent. +noedns clears the remembered EDNS version.

    +[no]multiline

    Print records like the SOA records in a verbose multi-line format with human-readable comments. The default is to print each record on a single line, to facilitate machine parsing of the dig output.

    +[no]fail

    Do not try the next server if you receive a SERVFAIL. The default is to not try the next server which is the reverse of normal stub resolver behavior.

    +[no]besteffort

    Attempt to display the contents of messages which are malformed. The default is to not display malformed answers.

    +[no]dnssec

    Requests DNSSEC records be sent by setting the DNSSEC OK bit (DO) in the OPT record in the additional section of the query.

    +[no]sigchase

    Chase DNSSEC signature chains. Requires dig be compiled with -DDIG_SIGCHASE.

    +trusted-key=####

    Specifies a file containing trusted keys to be used with +sigchase. Each DNSKEY record must be on its own line.

    If not specified, dig will look for /etc/trusted-key.key then trusted-key.key in the current directory.

    Requires dig be compiled with -DDIG_SIGCHASE.

    +[no]topdown

    When chasing DNSSEC signature chains perform a top-down validation. Requires dig be compiled with -DDIG_SIGCHASE.

    +[no]nsid

    Include an EDNS name server ID request when sending a query.

    MULTIPLE QUERIES

    The BIND 9 implementation of dig supports specifying multiple queries on the command line (in addition to supporting the -f batch file option). Each of those queries can be supplied with its own set of flags, options and query options.

    In this case, each query argument represent an individual query in the command-line syntax described above. Each consists of any of the standard options and flags, the name to be looked up, an optional query type and class and any query options that should be applied to that query.

    A global set of query options, which should be applied to all queries, can also be supplied. These global query options must precede the first tuple of name, class, type, options, flags, and query options supplied on the command line. Any global query options (except the +[no]cmd option) can be overridden by a query-specific set of query options. For example: 

    dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr

    shows how dig could be used from the command line to make three lookups: an ANY query for www.isc.org, a reverse lookup of 127.0.0.1 and a query for the NS records of isc.org. A global query option of +qr is applied, so that dig shows the initial query it made for each lookup. The final query has a local query option of +noqr which means that dig will not print the initial query when it looks up the NS records for isc.org.

    IDN SUPPORT

    If dig has been built with IDN (internationalized domain name) support, it can accept and display non-ASCII domain names. dig appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the IDN_DISABLE environment variable. The IDN support is disabled if the variable is set when dig runs.

    Name

    dnssec-dsfromkey — DNSSEC DS RR generation tool

    Synopsis

    dnssec-dsfromkey [-v level] [-1] [-2] [-a alg] {keyfile}

    dnssec-dsfromkey {-s} [-v level] [-1] [-2] [-a alg] [-c class] [-d dir] {dnsname}

    DESCRIPTION

    dnssec-dsfromkey outputs the Delegation Signer (DS) resource record (RR), as defined in RFC 3658 and RFC 4509, for the given key(s).

    OPTIONS

    -1

    Use SHA-1 as the digest algorithm (the default is to use both SHA-1 and SHA-256).

    -2

    Use SHA-256 as the digest algorithm.

    -a algorithm

    Select the digest algorithm. The value of algorithm must be one of SHA-1 (SHA1) or SHA-256 (SHA256). These values are case insensitive.

    -v level

    Sets the debugging level.

    -s

    Keyset mode: in place of the keyfile name, the argument is the DNS domain name of a keyset file. Following options make sense only in this mode.

    -c class

    Specifies the DNS class (default is IN), useful only in the keyset mode.

    -d directory

    Look for keyset files in directory as the directory, ignored when not in the keyset mode.

    EXAMPLE

    To build the SHA-256 DS RR from the Kexample.com.+003+26160 keyfile name, the following command would be issued:

    dnssec-dsfromkey -2 Kexample.com.+003+26160

    The command would print something like:

    example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94

    FILES

    The keyfile can be designed by the key identification Knnnn.+aaa+iiiii or the full file name Knnnn.+aaa+iiiii.key as generated by dnssec-keygen(8).

    The keyset file name is built from the directory, the string keyset- and the dnsname.

    CAVEAT

    A keyfile error can give a "file not found" even if the file exists.

    dnssec-keyfromlabel — DNSSEC key generation tool

    Synopsis

    dnssec-keyfromlabel {-a algorithm} {-l label} [-c class] [-f flag] [-k] [-n nametype] [-p protocol] [-t type] [-v level] {name}

    DESCRIPTION

    dnssec-keyfromlabel gets keys with the given label from a crypto hardware and builds key files for DNSSEC (Secure DNS), as defined in RFC 2535 and RFC 4034.

    OPTIONS

    -a algorithm

    Selects the cryptographic algorithm. The value of algorithm must be one of RSAMD5, RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512 or DH (Diffie Hellman). These values are case insensitive.

    If no algorithm is specified, then RSASHA1 will be used by default, unless the -3 option is specified, in which case NSEC3RSASHA1 will be used instead. (If -3 is used and an algorithm is specified, that algorithm will be checked for compatibility with NSEC3.)

    Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended.

    Note 2: DH automatically sets the -k flag.

    -l label

    Specifies the label of keys in the crypto hardware (PKCS#11 device).

    -n nametype

    Specifies the owner type of the key. The value of nametype must either be ZONE (for a DNSSEC zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)), USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). These values are case insensitive.

    -c class

    Indicates that the DNS record containing the key should have the specified class. If not specified, class IN is used.

    -f flag

    Set the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flag is KSK (Key Signing Key) DNSKEY.

    -h

    Prints a short summary of the options and arguments to dnssec-keygen.

    -k

    Generate KEY records rather than DNSKEY records.

    -p protocol

    Sets the protocol value for the generated key. The protocol is a number between 0 and 255. The default is 3 (DNSSEC). Other possible values for this argument are listed in RFC 2535 and its successors.

    -t type

    Indicates the use of the key. type must be one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default is AUTHCONF. AUTH refers to the ability to authenticate data, and CONF the ability to encrypt data.

    -v level

    Sets the debugging level.

    GENERATED KEY FILES

    When dnssec-keyfromlabel completes successfully, it prints a string of the form Knnnn.+aaa+iiiii to the standard output. This is an identification string for the key files it has generated.

    • nnnn is the key name.

    • aaa is the numeric representation of the algorithm.

    • iiiii is the key identifier (or footprint).

    dnssec-keyfromlabel creates two files, with names based on the printed string. Knnnn.+aaa+iiiii.key contains the public key, and Knnnn.+aaa+iiiii.private contains the private key.

    The .key file contains a DNS KEY record that can be inserted into a zone file (directly or with a $INCLUDE statement).

    The .private file contains algorithm specific fields. For obvious security reasons, this file does not have general read permission.

    dnssec-keygen — DNSSEC key generation tool

    Synopsis

    dnssec-keygen {-a algorithm} {-b keysize} {-n nametype} [-c class] [-e] [-f flag] [-g generator] [-h] [-k] [-p protocol] [-r randomdev] [-s strength] [-t type] [-v level] {name}

    DESCRIPTION

    dnssec-keygen generates keys for DNSSEC (Secure DNS), as defined in RFC 2535 and RFC 4034. It can also generate keys for use with TSIG (Transaction Signatures), as defined in RFC 2845.

    The name of the key is specified on the command line. For DNSSEC keys, this must match the name of the zone for which the key is being generated.

    OPTIONS

    -a algorithm

    Selects the cryptographic algorithm. For DNSSEC keys, the value of algorithm must be one of RSAMD5, RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256 or RSASHA512. For TSIG/TKEY, the value must be DH (Diffie Hellman), HMAC-MD5, HMAC-SHA1, HMAC-SHA224, HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512. These values are case insensitive.

    Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended. For TSIG, HMAC-MD5 is mandatory.

    Note 2: HMAC-MD5 and DH automatically set the -k flag.

    -b keysize

    Specifies the number of bits in the key. The choice of key size depends on the algorithm used. RSA keys must be between 512 and 2048 bits. Diffie Hellman keys must be between 128 and 4096 bits. DSA keys must be between 512 and 1024 bits and an exact multiple of 64. HMAC keys must be between 1 and 512 bits.

    -n nametype

    Specifies the owner type of the key. The value of nametype must either be ZONE (for a DNSSEC zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)), USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). These values are case insensitive. Defaults to ZONE for DNSKEY generation.

    -c class

    Indicates that the DNS record containing the key should have the specified class. If not specified, class IN is used.

    -e

    If generating an RSAMD5/RSASHA1 key, use a large exponent.

    -f flag

    Set the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flag is KSK (Key Signing Key) DNSKEY.

    -g generator

    If generating a Diffie Hellman key, use this generator. Allowed values are 2 and 5. If no generator is specified, a known prime from RFC 2539 will be used if possible; otherwise the default is 2.

    -h

    Prints a short summary of the options and arguments to dnssec-keygen.

    -k

    Generate KEY records rather than DNSKEY records.

    -p protocol

    Sets the protocol value for the generated key. The protocol is a number between 0 and 255. The default is 3 (DNSSEC). Other possible values for this argument are listed in RFC 2535 and its successors.

    -r randomdev

    Specifies the source of randomness. If the operating system does not provide a /dev/random or equivalent device, the default source of randomness is keyboard input. randomdev specifies the name of a character device or file containing random data to be used instead of the default. The special value keyboard indicates that keyboard input should be used.

    -s strength

    Specifies the strength value of the key. The strength is a number between 0 and 15, and currently has no defined purpose in DNSSEC.

    -t type

    Indicates the use of the key. type must be one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default is AUTHCONF. AUTH refers to the ability to authenticate data, and CONF the ability to encrypt data.

    -v level

    Sets the debugging level.

    GENERATED KEYS

    When dnssec-keygen completes successfully, it prints a string of the form Knnnn.+aaa+iiiii to the standard output. This is an identification string for the key it has generated.

    • nnnn is the key name.

    • aaa is the numeric representation of the algorithm.

    • iiiii is the key identifier (or footprint).

    dnssec-keygen creates two files, with names based on the printed string. Knnnn.+aaa+iiiii.key contains the public key, and Knnnn.+aaa+iiiii.private contains the private key.

    The .key file contains a DNS KEY record that can be inserted into a zone file (directly or with a $INCLUDE statement).

    The .private file contains algorithm-specific fields. For obvious security reasons, this file does not have general read permission.

    Both .key and .private files are generated for symmetric encryption algorithms such as HMAC-MD5, even though the public and private key are equivalent.

    EXAMPLE

    To generate a 768-bit DSA key for the domain example.com, the following command would be issued:

    dnssec-keygen -a DSA -b 768 -n ZONE example.com

    The command would print a string of the form:

    Kexample.com.+003+26160

    In this example, dnssec-keygen creates the files Kexample.com.+003+26160.key and Kexample.com.+003+26160.private.

    Name

    dnssec-signzone — DNSSEC zone signing tool

    Synopsis

    dnssec-signzone [-a] [-c class] [-d directory] [-e end-time] [-f output-file] [-g] [-h] [-k key] [-l domain] [-i interval] [-I input-format] [-j jitter] [-N soa-serial-format] [-o origin] [-O output-format] [-p] [-P] [-r randomdev] [-s start-time] [-t] [-v level] [-z] [-3 salt] [-H iterations] [-A] {zonefile} [key...]

    DESCRIPTION

    dnssec-signzone signs a zone. It generates NSEC and RRSIG records and produces a signed version of the zone. It also generates a keyset- file containing the key-signing keys for the zone, and if signing a zone which contains delegations, it can optionally generate DS records for the child zones from their keyset- files.

    OPTIONS

    -a

    Verify all generated signatures.

    -c class

    Specifies the DNS class of the zone.

    -k key

    Treat specified key as a key signing key ignoring any key flags. This option may be specified multiple times.

    -l domain

    Generate a DLV set in addition to the key (DNSKEY) and DS sets. The domain is appended to the name of the records.

    -d directory

    Look for keyset files in directory as the directory

    -g

    If the zone contains any delegations, and there are keyset- files for any of the child zones, then DS records for the child zones will be generated from the keys in those files. Existing DS records will be removed.

    -s start-time

    Specify the date and time when the generated RRSIG records become valid. This can be either an absolute or relative time. An absolute start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative start time is indicated by +N, which is N seconds from the current time. If no start-time is specified, the current time minus 1 hour (to allow for clock skew) is used.

    -e end-time

    Specify the date and time when the generated RRSIG records expire. As with start-time, an absolute time is indicated in YYYYMMDDHHMMSS notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A time relative to the current time is indicated with now+N. If no end-time is specified, 30 days from the start time is used as a default.

    -f output-file

    The name of the output file containing the signed zone. The default is to append .signed to the input filename.

    -h

    Prints a short summary of the options and arguments to dnssec-signzone.

    -i interval

    When a previously-signed zone is passed as input, records may be resigned. The interval option specifies the cycle interval as an offset from the current time (in seconds). If a RRSIG record expires after the cycle interval, it is retained. Otherwise, it is considered to be expiring soon, and it will be replaced.

    The default cycle interval is one quarter of the difference between the signature end and start times. So if neither end-time or start-time are specified, dnssec-signzone generates signatures that are valid for 30 days, with a cycle interval of 7.5 days. Therefore, if any existing RRSIG records are due to expire in less than 7.5 days, they would be replaced.

    -I input-format

    The format of the input zone file. Possible formats are "text" (default) and "raw". This option is primarily intended to be used for dynamic signed zones so that the dumped zone file in a non-text format containing updates can be signed directly. The use of this option does not make much sense for non-dynamic zones.

    -j jitter

    When signing a zone with a fixed signature lifetime, all RRSIG records issued at the time of signing expires simultaneously. If the zone is incrementally signed, i.e. a previously-signed zone is passed as input to the signer, all expired signatures have to be regenerated at about the same time. The jitter option specifies a jitter window that will be used to randomize the signature expire time, thus spreading incremental signature regeneration over time.

    Signature lifetime jitter also to some extent benefits validators and servers by spreading out cache expiration, i.e. if large numbers of RRSIGs don't expire at the same time from all caches there will be less congestion than if all validators need to refetch at mostly the same time.

    -n ncpus

    Specifies the number of threads to use. By default, one thread is started for each detected CPU.

    -N soa-serial-format

    The SOA serial number format of the signed zone. Possible formats are "keep" (default), "increment" and "unixtime".

    "keep"

    Do not modify the SOA serial number.

    "increment"

    Increment the SOA serial number using RFC 1982 arithmetics.

    "unixtime"

    Set the SOA serial number to the number of seconds since epoch.

    -o origin

    The zone origin. If not specified, the name of the zone file is assumed to be the origin.

    -O output-format

    The format of the output file containing the signed zone. Possible formats are "text" (default) and "raw".

    -p

    Use pseudo-random data when signing the zone. This is faster, but less secure, than using real random data. This option may be useful when signing large zones or when the entropy source is limited.

    -P

    Disable post sign verification tests.

    The post sign verification test ensures that for each algorithm in use there is at least one non revoked self signed KSK key, that all revoked KSK keys are self signed, and that all records in the zone are signed by the algorithm. This option skips these tests.

    -r randomdev

    Specifies the source of randomness. If the operating system does not provide a /dev/random or equivalent device, the default source of randomness is keyboard input. randomdev specifies the name of a character device or file containing random data to be used instead of the default. The special value keyboard indicates that keyboard input should be used.

    -t

    Print statistics at completion.

    -v level

    Sets the debugging level.

    -z

    Ignore KSK flag on key when determining what to sign.

    -3 salt

    Generate a NSEC3 chain with the given hex encoded salt. A dash (salt) can be used to indicate that no salt is to be used when generating the NSEC3 chain.

    -H iterations

    When generating a NSEC3 chain use this many interations. The default is 100.

    -A

    When generating a NSEC3 chain set the OPTOUT flag on all NSEC3 records and do not generate NSEC3 records for insecure delegations.

    zonefile

    The file containing the zone to be signed.

    key

    Specify which keys should be used to sign the zone. If no keys are specified, then the zone will be examined for DNSKEY records at the zone apex. If these are found and there are matching private keys, in the current directory, then these will be used for signing.

    EXAMPLE

    The following command signs the example.com zone with the DSA key generated by dnssec-keygen (Kexample.com.+003+17247). The zone's keys must be in the master file (db.example.com). This invocation looks for keyset files, in the current directory, so that DS records can be generated from them (-g). 

    % dnssec-signzone -g -o example.com db.example.com \
Kexample.com.+003+17247
db.example.com.signed
%

    In the above example, dnssec-signzone creates the file db.example.com.signed. This file should be referenced in a zone statement in a named.conf file.

    This example re-signs a previously signed zone with default parameters. The private keys are assumed to be in the current directory. 

    % cp db.example.com.signed db.example.com
% dnssec-signzone -o example.com db.example.com
db.example.com.signed
%

    KNOWN BUGS

    dnssec-signzone was designed so that it could sign a zone partially, using only a subset of the DNSSEC keys needed to produce a fully-signed zone. This permits a zone administrator, for example, to sign a zone with one key on one machine, move the resulting partially-signed zone to a second machine, and sign it again with a second key.

    An unfortunate side-effect of this flexibility is that dnssec-signzone does not check to make sure it's signing a zone with any valid keys at all. An attempt to sign a zone without any keys will appear to succeed, producing a "signed" zone with no signatures. There is no warning issued when a zone is not fully signed.

    This will be corrected in a future release. In the meantime, ISC recommends examining the output of dnssec-signzone to confirm that the zone is properly signed by all keys before using it.

    Name

    host — DNS lookup utility

    Synopsis

    host [-aCdlnrsTwv] [-c class] [-N ndots] [-R number] [-t type] [-W wait] [-m flag] [-4] [-6] {name} [server]

    DESCRIPTION

    host is a simple utility for performing DNS lookups. It is normally used to convert names to IP addresses and vice versa. When no arguments or options are given, host prints a short summary of its command line arguments and options.

    name is the domain name that is to be looked up. It can also be a dotted-decimal IPv4 address or a colon-delimited IPv6 address, in which case host will by default perform a reverse lookup for that address. server is an optional argument which is either the name or IP address of the name server that host should query instead of the server or servers listed in /etc/resolv.conf.

    The -a (all) option is equivalent to setting the -v option and asking host to make a query of type ANY.

    When the -C option is used, host will attempt to display the SOA records for zone name from all the listed authoritative name servers for that zone. The list of name servers is defined by the NS records that are found for the zone.

    The -c option instructs to make a DNS query of class class. This can be used to lookup Hesiod or Chaosnet class resource records. The default class is IN (Internet).

    Verbose output is generated by host when the -d or -v option is used. The two options are equivalent. They have been provided for backwards compatibility. In previous versions, the -d option switched on debugging traces and -v enabled verbose output.

    List mode is selected by the -l option. This makes host perform a zone transfer for zone name. Transfer the zone printing out the NS, PTR and address records (A/AAAA). If combined with -a all records will be printed.

    The -i option specifies that reverse lookups of IPv6 addresses should use the IP6.INT domain as defined in RFC1886. The default is to use IP6.ARPA.

    The -N option sets the number of dots that have to be in name for it to be considered absolute. The default value is that defined using the ndots statement in /etc/resolv.conf, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the search or domain directive in /etc/resolv.conf.

    The number of UDP retries for a lookup can be changed with the -R option. number indicates how many times host will repeat a query that does not get answered. The default number of retries is 1. If number is negative or zero, the number of retries will default to 1.

    Non-recursive queries can be made via the -r option. Setting this option clears the RD — recursion desired — bit in the query which host makes. This should mean that the name server receiving the query will not attempt to resolve name. The -r option enables host to mimic the behavior of a name server by making non-recursive queries and expecting to receive answers to those queries that are usually referrals to other name servers.

    By default, host uses UDP when making queries. The -T option makes it use a TCP connection when querying the name server. TCP will be automatically selected for queries that require it, such as zone transfer (AXFR) requests.

    The -4 option forces host to only use IPv4 query transport. The -6 option forces host to only use IPv6 query transport.

    The -t option is used to select the query type. type can be any recognized query type: CNAME, NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified, host automatically selects an appropriate query type. By default, it looks for A, AAAA, and MX records, but if the -C option was given, queries will be made for SOA records, and if name is a dotted-decimal IPv4 address or colon-delimited IPv6 address, host will query for PTR records. If a query type of IXFR is chosen the starting serial number can be specified by appending an equal followed by the starting serial number (e.g. -t IXFR=12345678).

    The time to wait for a reply can be controlled through the -W and -w options. The -W option makes host wait for wait seconds. If wait is less than one, the wait interval is set to one second. When the -w option is used, host will effectively wait forever for a reply. The time to wait for a response will be set to the number of seconds given by the hardware's maximum value for an integer quantity.

    The -s option tells host not to send the query to the next nameserver if any server responds with a SERVFAIL response, which is the reverse of normal stub resolver behavior.

    The -m can be used to set the memory usage debugging flags record, usage and trace.

    IDN SUPPORT

    If host has been built with IDN (internationalized domain name) support, it can accept and display non-ASCII domain names. host appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server. If you'd like to turn off the IDN support for some reason, defines the IDN_DISABLE environment variable. The IDN support is disabled if the variable is set when host runs.

    Name

    named-checkzone, named-compilezone — zone file validity checking or converting tool

    Synopsis

    named-checkzone [-d] [-h] [-j] [-q] [-v] [-c class] [-f format] [-F format] [-i mode] [-k mode] [-m mode] [-M mode] [-n mode] [-s style] [-S mode] [-t directory] [-w directory] [-D] [-W mode] {zonename} {filename}

    DESCRIPTION

    named-checkzone checks the syntax and integrity of a zone file. It performs the same checks as named does when loading a zone. This makes named-checkzone useful for checking zone files before configuring them into a name server.

    named-compilezone is similar to named-checkzone, but it always dumps the zone contents to a specified file in a specified format. Additionally, it applies stricter check levels by default, since the dump output will be used as an actual zone file loaded by named. When manually specified otherwise, the check levels must at least be as strict as those specified in the named configuration file.

    OPTIONS

    -d

    Enable debugging.

    -h

    Print the usage summary and exit.

    -q

    Quiet mode - exit code only.

    -v

    Print the version of the named-checkzone program and exit.

    -j

    When loading the zone file read the journal if it exists.

    -c class

    Specify the class of the zone. If not specified, "IN" is assumed.

    -i mode

    Perform post-load zone integrity checks. Possible modes are "full" (default), "full-sibling", "local", "local-sibling" and "none".

    Mode "full" checks that MX records refer to A or AAAA record (both in-zone and out-of-zone hostnames). Mode "local" only checks MX records which refer to in-zone hostnames.

    Mode "full" checks that SRV records refer to A or AAAA record (both in-zone and out-of-zone hostnames). Mode "local" only checks SRV records which refer to in-zone hostnames.

    Mode "full" checks that delegation NS records refer to A or AAAA record (both in-zone and out-of-zone hostnames). It also checks that glue address records in the zone match those advertised by the child. Mode "local" only checks NS records which refer to in-zone hostnames or that some required glue exists, that is when the nameserver is in a child zone.

    Mode "full-sibling" and "local-sibling" disable sibling glue checks but are otherwise the same as "full" and "local" respectively.

    Mode "none" disables the checks.

    -f format

    Specify the format of the zone file. Possible formats are "text" (default) and "raw".

    -F format

    Specify the format of the output file specified. Possible formats are "text" (default) and "raw". For named-checkzone, this does not cause any effects unless it dumps the zone contents.

    -k mode

    Perform "check-names" checks with the specified failure mode. Possible modes are "fail" (default for named-compilezone), "warn" (default for named-checkzone) and "ignore".

    -m mode

    Specify whether MX records should be checked to see if they are addresses. Possible modes are "fail", "warn" (default) and "ignore".

    -M mode

    Check if a MX record refers to a CNAME. Possible modes are "fail", "warn" (default) and "ignore".

    -n mode

    Specify whether NS records should be checked to see if they are addresses. Possible modes are "fail" (default for named-compilezone), "warn" (default for named-checkzone) and "ignore".

    -o filename

    Write zone output to filename. If filename is - then write to standard out. This is mandatory for named-compilezone.

    -s style

    Specify the style of the dumped zone file. Possible styles are "full" (default) and "relative". The full format is most suitable for processing automatically by a separate script. On the other hand, the relative format is more human-readable and is thus suitable for editing by hand. For named-checkzone this does not cause any effects unless it dumps the zone contents. It also does not have any meaning if the output format is not text.

    -S mode

    Check if a SRV record refers to a CNAME. Possible modes are "fail", "warn" (default) and "ignore".

    -t directory

    Chroot to directory so that include directives in the configuration file are processed as if run by a similarly chrooted named.

    -w directory

    chdir to directory so that relative filenames in master file $INCLUDE directives work. This is similar to the directory clause in named.conf.

    -D

    Dump zone file in canonical format. This is always enabled for named-compilezone.

    -W mode

    Specify whether to check for non-terminal wildcards. Non-terminal wildcards are almost always the result of a failure to understand the wildcard matching algorithm (RFC 1034). Possible modes are "warn" (default) and "ignore".

    zonename

    The domain name of the zone being checked.

    filename

    The name of the zone file.

    RETURN VALUES

    named-checkzone returns an exit status of 1 if errors were detected and 0 otherwise.

    Name

    named — Internet domain name server

    Synopsis

    named [-4] [-6] [-c config-file] [-d debug-level] [-f] [-g] [-m flag] [-n #cpus] [-p port] [-s] [-S #max-socks] [-t directory] [-u user] [-v] [-V] [-x cache-file]

    DESCRIPTION

    named is a Domain Name System (DNS) server, part of the BIND 9 distribution from ISC. For more information on the DNS, see RFCs 1033, 1034, and 1035.

    When invoked without arguments, named will read the default configuration file /etc/named.conf, read any initial data, and listen for queries.

    OPTIONS

    -4

    Use IPv4 only even if the host machine is capable of IPv6. -4 and -6 are mutually exclusive.

    -6

    Use IPv6 only even if the host machine is capable of IPv4. -4 and -6 are mutually exclusive.

    -c config-file

    Use config-file as the configuration file instead of the default, /etc/named.conf. To ensure that reloading the configuration file continues to work after the server has changed its working directory due to to a possible directory option in the configuration file, config-file should be an absolute pathname.

    -d debug-level

    Set the daemon's debug level to debug-level. Debugging traces from named become more verbose as the debug level increases.

    -f

    Run the server in the foreground (i.e. do not daemonize).

    -g

    Run the server in the foreground and force all logging to stderr.

    -m flag

    Turn on memory usage debugging flags. Possible flags are usage, trace, record, size, and mctx. These correspond to the ISC_MEM_DEBUGXXXX flags described in <isc/mem.h>.

    -n #cpus

    Create #cpus worker threads to take advantage of multiple CPUs. If not specified, named will try to determine the number of CPUs present and create one thread per CPU. If it is unable to determine the number of CPUs, a single worker thread will be created.

    -p port

    Listen for queries on port port. If not specified, the default is port 53.

    -s

    Write memory usage statistics to stdout on exit.

    Note

    This option is mainly of interest to BIND 9 developers and may be removed or changed in a future release.

    -S #max-socks

    Allow named to use up to #max-socks sockets.

    Warning

    This option should be unnecessary for the vast majority of users. The use of this option could even be harmful because the specified value may exceed the limitation of the underlying system API. It is therefore set only when the default configuration causes exhaustion of file descriptors and the operational environment is known to support the specified number of sockets. Note also that the actual maximum number is normally a little fewer than the specified value because named reserves some file descriptors for its internal use.

    -t directory

    Chroot to directory after processing the command line arguments, but before reading the configuration file.

    Warning

    This option should be used in conjunction with the -u option, as chrooting a process running as root doesn't enhance security on most systems; the way chroot(2) is defined allows a process with root privileges to escape a chroot jail.

    -u user

    Setuid to user after completing privileged operations, such as creating sockets that listen on privileged ports.

    Note

    On Linux, named uses the kernel's capability mechanism to drop all root privileges except the ability to bind(2) to a privileged port and set process resource limits. Unfortunately, this means that the -u option only works when named is run on kernel 2.2.18 or later, or kernel 2.3.99-pre3 or later, since previous kernels did not allow privileges to be retained after setuid(2).

    -v

    Report the version number and exit.

    -V

    Report the version number and build options, and exit.

    -x cache-file

    Load data from cache-file into the cache of the default view.

    Warning

    This option must not be used. It is only of interest to BIND 9 developers and may be removed or changed in a future release.

    SIGNALS

    In routine operation, signals should not be used to control the nameserver; rndc should be used instead.

    SIGHUP

    Force a reload of the server.

    SIGINT, SIGTERM

    Shut down the server.

    The result of sending any other signals to the server is undefined.

    CONFIGURATION

    The named configuration file is too complex to describe in detail here. A complete description is provided in the BIND 9 Administrator Reference Manual.

    named inherits the umask (file creation mode mask) from the parent process. If files created by named, such as journal files, need to have custom permissions, the umask should be set explicitly in the script used to start the named process.

    FILES

    /etc/named.conf

    The default configuration file.

    /var/run/named/named.pid

    The default process-id file.

    Name

    nsupdate — Dynamic DNS update utility

    Synopsis

    nsupdate [-d] [-D] [[-g] | [-o] | [-y [hmac:]keyname:secret] | [-k keyfile]] [-t timeout] [-u udptimeout] [-r udpretries] [-R randomdev] [-v] [filename]

    DESCRIPTION

    nsupdate is used to submit Dynamic DNS Update requests as defined in RFC2136 to a name server. This allows resource records to be added or removed from a zone without manually editing the zone file. A single update request can contain requests to add or remove more than one resource record.

    Zones that are under dynamic control via nsupdate or a DHCP server should not be edited by hand. Manual edits could conflict with dynamic updates and cause data to be lost.

    The resource records that are dynamically added or removed with nsupdate have to be in the same zone. Requests are sent to the zone's master server. This is identified by the MNAME field of the zone's SOA record.

    The -d option makes nsupdate operate in debug mode. This provides tracing information about the update requests that are made and the replies received from the name server.

    The -D option makes nsupdate report additional debugging information to -d.

    Transaction signatures can be used to authenticate the Dynamic DNS updates. These use the TSIG resource record type described in RFC2845 or the SIG(0) record described in RFC3535 and RFC2931 or GSS-TSIG as described in RFC3645. TSIG relies on a shared secret that should only be known to nsupdate and the name server. Currently, the only supported encryption algorithm for TSIG is HMAC-MD5, which is defined in RFC 2104. Once other algorithms are defined for TSIG, applications will need to ensure they select the appropriate algorithm as well as the key when authenticating each other. For instance, suitable key and server statements would be added to /etc/named.conf so that the name server can associate the appropriate secret key and algorithm with the IP address of the client application that will be using TSIG authentication. SIG(0) uses public key cryptography. To use a SIG(0) key, the public key must be stored in a KEY record in a zone served by the name server. nsupdate does not read /etc/named.conf. GSS-TSIG uses Kerberos credentials.

    nsupdate uses the -y or -k option to provide the shared secret needed to generate a TSIG record for authenticating Dynamic DNS update requests, default type HMAC-MD5. These options are mutually exclusive. With the -k option, nsupdate reads the shared secret from the file keyfile, whose name is of the form K{name}.+157.+{random}.private. For historical reasons, the file K{name}.+157.+{random}.key must also be present. When the -y option is used, a signature is generated from [hmac:]keyname:secret. keyname is the name of the key, and secret is the base64 encoded shared secret. Use of the -y option is discouraged because the shared secret is supplied as a command line argument in clear text. This may be visible in the output from ps(1) or in a history file maintained by the user's shell.

    The -k may also be used to specify a SIG(0) key used to authenticate Dynamic DNS update requests. In this case, the key specified is not an HMAC-MD5 key.

    The -g and -o specify that GSS-TSIG is to be used. The -o should only be used with old Microsoft Windows 2000 servers.

    By default, nsupdate uses UDP to send update requests to the name server unless they are too large to fit in a UDP request in which case TCP will be used. The -v option makes nsupdate use a TCP connection. This may be preferable when a batch of update requests is made.

    The -t option sets the maximum time an update request can take before it is aborted. The default is 300 seconds. Zero can be used to disable the timeout.

    The -u option sets the UDP retry interval. The default is 3 seconds. If zero, the interval will be computed from the timeout interval and number of UDP retries.

    The -r option sets the number of UDP retries. The default is 3. If zero, only one update request will be made.

    The -R randomdev option specifies a source of randomness. If the operating system does not provide a /dev/random or equivalent device, the default source of randomness is keyboard input. randomdev specifies the name of a character device or file containing random data to be used instead of the default. The special value keyboard indicates that keyboard input should be used. This option may be specified multiple times.

    INPUT FORMAT

    nsupdate reads input from filename or standard input. Each command is supplied on exactly one line of input. Some commands are for administrative purposes. The others are either update instructions or prerequisite checks on the contents of the zone. These checks set conditions that some name or set of resource records (RRset) either exists or is absent from the zone. These conditions must be met if the entire update request is to succeed. Updates will be rejected if the tests for the prerequisite conditions fail.

    Every update request consists of zero or more prerequisites and zero or more updates. This allows a suitably authenticated update request to proceed if some specified resource records are present or missing from the zone. A blank input line (or the send command) causes the accumulated commands to be sent as one Dynamic DNS update request to the name server.

    The command formats and their meaning are as follows:

    server {servername} [port]

    Sends all dynamic update requests to the name server servername. When no server statement is provided, nsupdate will send updates to the master server of the correct zone. The MNAME field of that zone's SOA record will identify the master server for that zone. port is the port number on servername where the dynamic update requests get sent. If no port number is specified, the default DNS port number of 53 is used.

    local {address} [port]

    Sends all dynamic update requests using the local address. When no local statement is provided, nsupdate will send updates using an address and port chosen by the system. port can additionally be used to make requests come from a specific port. If no port number is specified, the system will assign one.

    zone {zonename}

    Specifies that all updates are to be made to the zone zonename. If no zone statement is provided, nsupdate will attempt determine the correct zone to update based on the rest of the input.

    class {classname}

    Specify the default class. If no class is specified, the default class is IN.

    ttl {seconds}

    Specify the default time to live for records to be added. The value none will clear the default ttl.

    key {name} {secret}

    Specifies that all updates are to be TSIG-signed using the keyname keysecret pair. The key command overrides any key specified on the command line via -y or -k.

    gsstsig

    Use GSS-TSIG to sign the updated. This is equivalent to specifying -g on the commandline.

    oldgsstsig

    Use the Windows 2000 version of GSS-TSIG to sign the updated. This is equivalent to specifying -o on the commandline.

    realm {[realm_name]}

    When using GSS-TSIG use realm_name rather than the default realm in krb5.conf. If no realm is specified the saved realm is cleared.

    prereq nxdomain {domain-name}

    Requires that no resource record of any type exists with name domain-name.

    prereq yxdomain {domain-name}

    Requires that domain-name exists (has as at least one resource record, of any type).

    prereq nxrrset {domain-name} [class] {type}

    Requires that no resource record exists of the specified type, class and domain-name. If class is omitted, IN (internet) is assumed.

    prereq yxrrset {domain-name} [class] {type}

    This requires that a resource record of the specified type, class and domain-name must exist. If class is omitted, IN (internet) is assumed.

    prereq yxrrset {domain-name} [class] {type} {data...}

    The data from each set of prerequisites of this form sharing a common type, class, and domain-name are combined to form a set of RRs. This set of RRs must exactly match the set of RRs existing in the zone at the given type, class, and domain-name. The data are written in the standard text representation of the resource record's RDATA.

    update delete {domain-name} [ttl] [class] [type [data...]]

    Deletes any resource records named domain-name. If type and data is provided, only matching resource records will be removed. The internet class is assumed if class is not supplied. The ttl is ignored, and is only allowed for compatibility.

    update add {domain-name} {ttl} [class] {type} {data...}

    Adds a new resource record with the specified ttl, class and data.

    show

    Displays the current message, containing all of the prerequisites and updates specified since the last send.

    send

    Sends the current message. This is equivalent to entering a blank line.

    answer

    Displays the answer.

    debug

    Turn on debugging.

    Lines beginning with a semicolon are comments and are ignored.

    EXAMPLES

    The examples below show how nsupdate could be used to insert and delete resource records from the example.com zone. Notice that the input in each example contains a trailing blank line so that a group of commands are sent as one dynamic update request to the master name server for example.com. 

    # nsupdate
> update delete oldhost.example.com A
> update add newhost.example.com 86400 A 172.16.1.1
> send

    Any A records for oldhost.example.com are deleted. And an A record for newhost.example.com with IP address 172.16.1.1 is added. The newly-added record has a 1 day TTL (86400 seconds). 

    # nsupdate
> prereq nxdomain nickname.example.com
> update add nickname.example.com 86400 CNAME somehost.example.com
> send

    The prerequisite condition gets the name server to check that there are no resource records of any type for nickname.example.com. If there are, the update request fails. If this name does not exist, a CNAME for it is added. This ensures that when the CNAME is added, it cannot conflict with the long-standing rule in RFC1034 that a name must not exist as any other record type if it exists as a CNAME. (The rule has been updated for DNSSEC in RFC2535 to allow CNAMEs to have RRSIG, DNSKEY and NSEC records.)

    BUGS

    The TSIG key is redundantly stored in two separate files. This is a consequence of nsupdate using the DST library for its cryptographic operations, and may change in future releases.

    Name

    rndc-confgen — rndc key generation tool

    Synopsis

    rndc-confgen [-a] [-b keysize] [-c keyfile] [-h] [-k keyname] [-p port] [-r randomfile] [-s address] [-t chrootdir] [-u user]

    DESCRIPTION

    rndc-confgen generates configuration files for rndc. It can be used as a convenient alternative to writing the rndc.conf file and the corresponding controls and key statements in named.conf by hand. Alternatively, it can be run with the -a option to set up a rndc.key file and avoid the need for a rndc.conf file and a controls statement altogether.

    OPTIONS

    -a

    Do automatic rndc configuration. This creates a file rndc.key in /etc (or whatever sysconfdir was specified as when BIND was built) that is read by both rndc and named on startup. The rndc.key file defines a default command channel and authentication key allowing rndc to communicate with named on the local host with no further configuration.

    Running rndc-confgen -a allows BIND 9 and rndc to be used as drop-in replacements for BIND 8 and ndc, with no changes to the existing BIND 8 named.conf file.

    If a more elaborate configuration than that generated by rndc-confgen -a is required, for example if rndc is to be used remotely, you should run rndc-confgen without the -a option and set up a rndc.conf and named.conf as directed.

    -b keysize

    Specifies the size of the authentication key in bits. Must be between 1 and 512 bits; the default is 128.

    -c keyfile

    Used with the -a option to specify an alternate location for rndc.key.

    -h

    Prints a short summary of the options and arguments to rndc-confgen.

    -k keyname

    Specifies the key name of the rndc authentication key. This must be a valid domain name. The default is rndc-key.

    -p port

    Specifies the command channel port where named listens for connections from rndc. The default is 953.

    -r randomfile

    Specifies a source of random data for generating the authorization. If the operating system does not provide a /dev/random or equivalent device, the default source of randomness is keyboard input. randomdev specifies the name of a character device or file containing random data to be used instead of the default. The special value keyboard indicates that keyboard input should be used.

    -s address

    Specifies the IP address where named listens for command channel connections from rndc. The default is the loopback address 127.0.0.1.

    -t chrootdir

    Used with the -a option to specify a directory where named will run chrooted. An additional copy of the rndc.key will be written relative to this directory so that it will be found by the chrooted named.

    -u user

    Used with the -a option to set the owner of the rndc.key file generated. If -t is also specified only the file in the chroot area has its owner changed.

    EXAMPLES

    To allow rndc to be used with no manual configuration, run

    rndc-confgen -a

    To print a sample rndc.conf file and corresponding controls and key statements to be manually inserted into named.conf, run

    rndc-confgen

    Name

    rndc.conf — rndc configuration file

    Synopsis

    rndc.conf

    DESCRIPTION

    rndc.conf is the configuration file for rndc, the BIND 9 name server control utility. This file has a similar structure and syntax to named.conf. Statements are enclosed in braces and terminated with a semi-colon. Clauses in the statements are also semi-colon terminated. The usual comment styles are supported:

    C style: /* */

    C++ style: // to end of line

    Unix style: # to end of line

    rndc.conf is much simpler than named.conf. The file uses three statements: an options statement, a server statement and a key statement.

    The options statement contains five clauses. The default-server clause is followed by the name or address of a name server. This host will be used when no name server is given as an argument to rndc. The default-key clause is followed by the name of a key which is identified by a key statement. If no keyid is provided on the rndc command line, and no key clause is found in a matching server statement, this default key will be used to authenticate the server's commands and responses. The default-port clause is followed by the port to connect to on the remote name server. If no port option is provided on the rndc command line, and no port clause is found in a matching server statement, this default port will be used to connect. The default-source-address and default-source-address-v6 clauses which can be used to set the IPv4 and IPv6 source addresses respectively.

    After the server keyword, the server statement includes a string which is the hostname or address for a name server. The statement has three possible clauses: key, port and addresses. The key name must match the name of a key statement in the file. The port number specifies the port to connect to. If an addresses clause is supplied these addresses will be used instead of the server name. Each address can take an optional port. If an source-address or source-address-v6 of supplied then these will be used to specify the IPv4 and IPv6 source addresses respectively.

    The key statement begins with an identifying string, the name of the key. The statement has two clauses. algorithm identifies the encryption algorithm for rndc to use; currently only HMAC-MD5 is supported. This is followed by a secret clause which contains the base-64 encoding of the algorithm's encryption key. The base-64 string is enclosed in double quotes.

    There are two common ways to generate the base-64 string for the secret. The BIND 9 program rndc-confgen can be used to generate a random key, or the mmencode program, also known as mimencode, can be used to generate a base-64 string from known input. mmencode does not ship with BIND 9 but is available on many systems. See the EXAMPLE section for sample command lines for each.

    EXAMPLE

          options {
        default-server  localhost;
        default-key     samplekey;
      };


          server localhost {
        key             samplekey;
      };


          server testserver {
        key		testkey;
        addresses	{ localhost port 5353; };
      };


          key samplekey {
        algorithm       hmac-md5;
        secret          "6FMfj43Osz4lyb24OIe2iGEz9lf1llJO+lz";
      };


          key testkey {
        algorithm	hmac-md5;
        secret		"R3HI8P6BKw9ZwXwN3VZKuQ==";
      };

    In the above example, rndc will by default use the server at localhost (127.0.0.1) and the key called samplekey. Commands to the localhost server will use the samplekey key, which must also be defined in the server's configuration file with the same name and secret. The key statement indicates that samplekey uses the HMAC-MD5 algorithm and its secret clause contains the base-64 encoding of the HMAC-MD5 secret enclosed in double quotes.

    If rndc -s testserver is used then rndc will connect to server on localhost port 5353 using the key testkey.

    To generate a random secret with rndc-confgen:

    rndc-confgen

    A complete rndc.conf file, including the randomly generated key, will be written to the standard output. Commented-out key and controls statements for named.conf are also printed.

    To generate a base-64 secret with mmencode:

    echo "known plaintext for a secret" | mmencode

    NAME SERVER CONFIGURATION

    The name server must be configured to accept rndc connections and to recognize the key specified in the rndc.conf file, using the controls statement in named.conf. See the sections on the controls statement in the BIND 9 Administrator Reference Manual for details.

    Name

    rndc — name server control utility

    Synopsis

    rndc [-b source-address] [-c config-file] [-k key-file] [-s server] [-p port] [-V] [-y key_id] {command}

    DESCRIPTION

    rndc controls the operation of a name server. It supersedes the ndc utility that was provided in old BIND releases. If rndc is invoked with no command line options or arguments, it prints a short summary of the supported commands and the available options and their arguments.

    rndc communicates with the name server over a TCP connection, sending commands authenticated with digital signatures. In the current versions of rndc and named, the only supported authentication algorithm is HMAC-MD5, which uses a shared secret on each end of the connection. This provides TSIG-style authentication for the command request and the name server's response. All commands sent over the channel must be signed by a key_id known to the server.

    rndc reads a configuration file to determine how to contact the name server and decide what algorithm and key it should use.

    OPTIONS

    -b source-address

    Use source-address as the source address for the connection to the server. Multiple instances are permitted to allow setting of both the IPv4 and IPv6 source addresses.

    -c config-file

    Use config-file as the configuration file instead of the default, /etc/rndc.conf.

    -k key-file

    Use key-file as the key file instead of the default, /etc/rndc.key. The key in /etc/rndc.key will be used to authenticate commands sent to the server if the config-file does not exist.

    -s server

    server is the name or address of the server which matches a server statement in the configuration file for rndc. If no server is supplied on the command line, the host named by the default-server clause in the options statement of the rndc configuration file will be used.

    -p port

    Send commands to TCP port port instead of BIND 9's default control channel port, 953.

    -V

    Enable verbose logging.

    -y key_id

    Use the key key_id from the configuration file. key_id must be known by named with the same algorithm and secret string in order for control message validation to succeed. If no key_id is specified, rndc will first look for a key clause in the server statement of the server being used, or if no server statement is present for that host, then the default-key clause of the options statement. Note that the configuration file contains shared secrets which are used to send authenticated control commands to name servers. It should therefore not have general read or write access.

    For the complete set of commands supported by rndc, see the BIND 9 Administrator Reference Manual or run rndc without arguments to see its help message.

    LIMITATIONS

    rndc does not yet support all the commands of the BIND 8 ndc utility.

    There is currently no way to provide the shared secret for a key_id without using the configuration file.

    Several error messages could be clearer.

Without such an option "dnssec-signer -N named.conf" couldn't find the zone file directory. * misc Default ZSK lifetime set to 12 weeks instead of 3 months (30days) to suppress the warning message about ZSK keysize of 512 bits. zkt 0.98 -- 28. Dec 2008 * misc Target "install-man" added to Makefile man files moved to sub directory "man" * func If a BIND version greater equal 9.6.0 is used, option -d doesn't initiate a resigning of a zone. It's just for key rollover. * func New pseudo algorithms for NSEC3 DNSKEYS added. Support of NSEC3 hashing if a BIND version greater equal 9.6.0 is used. New parameter "SaltBits" added to the config file to set the salt length in bits (default is 24 which means 6 hex nibbles). The number of hash iterations is set to the default value of dnssec-signzone which depends on key size. * misc Renaming of all example zone directories so that the directory name does not end with a dot (Necessary for installing the source tree in an MS-Windows environment). str_tolowerdup() renamed to domain_canonicdup() and code added to append a dot to the domain name if it's not already there. * misc Add 'sec' (second) qualifier to debug output in kskrollover(). * bug Remove a trailing '/' at the -D argument. * misc Configure script now uses the BIND_UTIL_PATH out of config_zkt.h if the BIND dnssec-signzone command is not found * bug A zone with only a standby key signing key (which means w/o an active ksk) aborts the dnssec-signer command.

Thanks to Shane Kerr for the suggestion. * bug Change of global configured key liftetime during a zone signing key rollover results in unnecessary additional pre-published zone signing keys (Thanks to Frank Behrens for the patch) * misc Sig_Random config file parameter defaults now to false * bug The man page refers the wrong licence (GPL instead of BSD) zkt 0.97 -- 5. Aug 2008 * bug LG_* logging level wasn't mapped to syslog level in lg_mesg(). gettock() in ncparse.c did not recognize C single line comments "//" (Thanks to Frank Behrens for finding this out) * misc dist_and_reload () now calls the "Distribute_Cmd" twice: First with argument "distribute" for signed zone file distribution, second with argument "reload" to initiate a reload. Again see example/flat/dist.sh for an example script. * bug full KSK rollover will (mostly) also work for dynamic zones This is a hack and requires further investigation. Currently it will not work if someone is using non standard zone file names. * misc default ZSK lifetime set to 3 month * misc get_mtime() renamed to file_mtime() * func is_exec_ok() added and called in dist_and_reload () * func New parameter "Distribute_Cmd" added for specifing a user defined distribution (and reload) command (See example/flat/dist.sh). * misc Changed wording to be a bit more consistent to draft-gudmundsson-life-of-dnskey-00.txt - State of published key will be print as "pub" instead of "pre" by dnssec-zkt. - Option --pre-publish of dnssec-zkt changed to --published. - Changed wording in all comments and log message from "pre-publish" to "published". * func Highly experimental code to do a full automatic ksk rollover in hierachical mode. ksk_rollover() added in rollover.c; parameter change for ksk_status() * misc Changed name of "dnssec-soaserial" to "zkt-soaserial" * bug Fixed verbose logging error if -N or -D option was used * func Some LG_INFO messages added about key status change * func Remove of function to register a new ksk (zktr.[ch]) * misc Changed licence from GNU GPLv2 to BSD licence * bug Fixed bug in logging of ZSK rollover * misc Changed tar file to zipped one and archive the files with toplevel directory * bug Fixed use of uninitialized vars in zconf.c (line) * port Preparation for use of autoconf - config.h renamed to config_zkt.h and change of include directives - conditional include of config.h - ./configure script is able to determine BIND utility path (BIND_UTIL_PATH) and version (BIND_VERSION) - compile time options are settable via configure script (--enable-xxx) - For now, the configure script is not able to set the install dir. * bug ksk rollover phase2 did not trigger resigning of parent (the parent file was copied to the parent directory only after child zone resigning) * bug fixed bad notice message in zskstatus () * func dnssec-zkt -Z print out syslog facility & level with upper case letter and without quotation marks * func Syslog facility DAEMON added zkt 0.96 -- 19. June 2008 * func Config file option "SIG_Parameter" added. * func Function verbmesg() added and used for verbose logging to stdout and/or to syslog resp. file. Config file parameter VerboseLog added to config file. * bug Option -O wasn't recognized by dnssec-signer * func Better support of initial setup of dynamic signed zones (just create an empty "zone.db.dsigned" file and run dnssec-signer with option -d). * func Improved error logging; incr_soa() errors are written as clear text message instead of error number * func elog_mesg() function replaced by a more general logging mechanism. ErrorLog config parameter replaced by LogFile, LogLevel and SyslogFacility, SyslogLevel parameter * func New function filesize() added * func dki_prt_trustedkey print out old key id if key is revoked * func dki_new() writes gentime (GMT) and proposed key lifetime (days) as comment into the *.key file * bug Doing some housekeeping zkt 0.95 -- 19. April 2008 * misc This is not a public released version of zkt. * func All config file option are now settable via commandline option -O (--option or --config-option) * misc Function fatal() now has an exit code of 127. This is necessary because values from 1 to 64 are reflecting the number of errors occured. * func Errorlog functionality added All dnssec-signer errors will be logged in the file specified by the Errorlog config file parameter or specified by the command line option -L (--errorlog). If a directory is given, then the logging will occur in a file within this directory which is named like "zkt-.log". The dnssec-signer command has an exit code of 0 if no error occured, an exit code of 127 on fatal errors, an exit code from 1 to 63 reflecting the number of errors occured, or an exit code of 64 if more than 63 errors occured. * func dnssec-signer: Introducing long options * bug New skript added to example/views directory to read in the right config file * func New option -f (--lifetime) and -F (--setlifetime) added to dnssec-zkt. * func New option -e (--expire) added to dnssec-zkt. (Seems to be that the dnssec-zkt command is a little bit overloaded with options.) * func dki.c and zkt.c supports storage of key lifetime, generation time and expiration time as a comment in the .key file. With this, it's possible to change the default lifetime without any impact on already used keys. zkt 0.94 -- 6. Dec 2007 * bug Case mismatch of zone name and key file name prevent dki_read() from reading the key. Thanks to Alan Clegg for finding this out. Added some additional error processing and convert zone name to lower case. * misc Builtin default for KSK_randfile changed from NULL to "/dev/urandom". * bug dnssec-signer has to use private keys for signing even if the revoke bit is set. To achieve this the file pattern K*.private is added to the dnssec-signzone run. * bug Uninitialized variable "len" in sign_zone(). * func Default config file is settable via environment variable ZKT_CONFFILE * func Support of views added Link dnssec-zkt to dnssec-zkt- and dnssec-signer to dnssec-signer-. Option -V and --view added to dnssec-zkt. Option -V added to dnssec-signer. View support added to parse_namedconf(). zkt 0.93 -- 1. Nov 2007 * func The ksk registration mechanism is disabled by default (see REG_URL in config.h). * func Basic support for revoke flag added (RFC5011). Semantic of option -R of dnssec-zkt changed. * func Undocumented option -S changed to lower case. Pre-pulished KSK will be shown as "standby" key. New Option -S (standby) for pre-publish KSK. * func New command dnssec-soaserial added. * bug dnssec-signer do not print the incremented serial number anymore. time2str() fixed bug in time format (HAS_STRFTIME=0). * port New build dependencies "solaris", "macos" and "help" added to Makefile. zkt 0.92 -- 1. Oct 2007 * func Parameter "Serialformat" in dnssec.conf added . Now it is possible to use the unixtime format for the SOA serial number. If you use BIND 9.4 or greater in conjunction with this, than there is no need for the special SOA serial formating in the zonefile. (Thanks to Jakob Schlyter for the -N option of dnssec-signzone and the suggestion to add the unixtime support to zkt) * func Option --ksk-roll-stat added. * port Added macro HAS_GETOPT_LONG to support OS with lack of getopt_long() (e.g. solaris). Options -[01239] added. * misc Unused macro HAS_ULONG removed from config.h. Deklaration of unsigned types moved from dki.h to config.h (so it will be available in _all_ source files). Thanks to Mans Nilsson. Unused macro isblank() (ncparse.c) removed. * bug In dosigning(): freeze the dynamic zone _before_ copying the zone file. zkt 0.91 -- 1. Apr 2007 * doc --ksk-rollover option added to usage(). * func some experimental code for dynamic zones added. new functions added: copyzonefile(), dyn_update_freeze(). New option "-d" added. zkt 0.90 -- 6. Dec 2006 * func CHECK_RESIGN interval added to config.h. This is the dnssec-signer calling interval (at least 1 day or 86400 sec). * func new function dki_destroy() added; semantic of dk_remove() changed to rename the key files instead of physical deletion. * doc Setup of new example directory (flat and hierarchical). * doc dnssec-zkt man page updated. Added some comments in misc.c * misc function strtaint() renamed to str_untaint(), dki_keycmp() renamed to dki_tagcmp(). * func New parameter key_ttl added to dnssec.conf. New func dki_prt_dnskeyttl () added. Now dnskey.db is written with key_ttl value. * func dnssec-signer: In hierarchical mode sign_zone() copies the parent-file (if such a file exist) instead of the keyset-file to the parent directory. * func dnssec-zkt: Option --ksk-roll-phase[123] and function ksk_rollover() added. * misc zconf: default values for sigvalidity, resign_int etc. changed, new dnssec.conf example file created. * func dnssec-zkt: Long option support added. zkt 0.83 -- 11. Sep 2006 * bug dosigning(): Fixed bug in the bug fixing of printing undefined serial number if incr_serial() failed. (Thanks to Randy McCasskill). zkt 0.82 -- 8. Sep 2006 * bug Use option -e for dnssec-keygen calls in dki_new(), because an RSA exponent of 3 is vulnerable. * bug dosigning(): Fixed bug in printing undefined serial number if incr_serial() failed. an RSA exponent of 3 is vulnerable. * bug dosigning(): Fixed bug in printing undefined serial number if incr_serial() failed. zkt 0.81 -- 13. July 2006 * bug The function ceatekey() won't work with USE_TREE. Size of MAX_DNAME increased. zkt 0.8 -- 09. July 2006 * func Now a hierarchical directory structure with subdomains stored in subfolders of the parent domain are allowed. Added copyfile(), cmpfile() and new_keysetfiles() for that. * func Config parameter added to choose if the domain name is right or left justified listed by dnssec-zkt (printkeyinfo). * func New class of key added ("sep"). A SEP key is a (public) key file without the private counterpart. So we could use the key solely as an secure entry point. (dki.h, dki_read). zkt 0.70 -- 15. Sep 2005 * func Experimental code added to use a binary search tree instead of a single linked list. This is mainly for performance improvement for large sites. If you don't want to use it, set USE_TREE in config.h to zero. In the first step only dnssec-zkt use the new data structure. The tree is build over the domain names and each node is the starting point of a linked list of keys. As a result, it's not possible anymore to search on key tags only. You have to specify the domain name plus the tag. :-( * func Function parseurl added. * func Experimental code to register a new ksk. Currently it's more like a key announcement because of the lack of identification and authentication. zkt 0.65 -- 22. Aug 2005 * misc Rewrite of the domaincmp() function. Now it's round about 2 times faster. After some additional changes and the compiler option -O3 the dnssec-zkt on the ~ 12000 zones requires only a minute $ time dnssec-zkt -z -r sec > /dev/null real 0m58.287s user 0m54.610s sys 0m3.680s * func A keyset directory is introduced (experimental) The parameter -d is added to the call of the dnssec-signzone command if the config option KeySetDir is set. As a result, all dsset-, keyset- and dlvset- files are stored in one directory. The advantage is, that the chain of trust of all local subzone is build automatically (This is the reason why we sort the zones with the child zones first). The disadvantage is that we store many files in single directory (3 files per zone). zkt 0.64 -- 1. Aug 2005 * bug The code for option -Z of dnssec-zkt should be executed before we read the complete directory tree. This is usefull if we have a very deep directory structure and the recursive flag is switched on. * func SIG_Pseudorand parameter added. * func ([KZ]SK)|(SIG)_randfile parameter added. * func measure the time used for signing of each zone. * bug function logflush() added to misc.c and called by dosigning(). * misc some perfomance test made: - Directory structure "sec//domain" with round about 12200 domains - One of the domain is a big one (~ 820000 RRs), the others are mostly very small ones - We use a dsa with 704 bits as ksk and a rsamd5 with 512 bits as zsk on each domain. - All test made on Sun Fire V440 with 4 CPU and 4x2GB main memory # sequential signing of all zones $ time dnssec-signer -v -v -f -D sec real 434m (~ 7h 14min) user 188 sys 175 # with option -p and -r /dev/urandom $ time dnssec-signer -v -v -f -D sec > log real 96m28.306s user 290m41.980s sys 6m13.790s # one process for each firstletter subdirectory $ time par_signer.sh real 394m12.334s user 295m58.390s sys 786m42.479s # with option -p and -r /dev/urandom $ time par_signer.sh real 78m49.323s user 284m58.350s sys 5m39.340s $ time dnssec-zkt -z -r sec > /dev/null real 2m5.722s user 2m0.060s sys 0m4.510s # signing the big (820000 RR) domain only $ time dnssec-signer -v -v -f -D sec/b/big-domain real 196m23.165 (~ 3h 16min) user 176m57.610 sys 167m27.570 # with option -p and -r /dev/urandom $ time dnssec-signer -v -v -f -D sec/b/big-domain real 49m53.152 user 173m59.520 sys 1m40.150 zkt 0.63 -- 14. June 2005 * bug allow TTL value in keyfiles (see TTL_IN_KEYFILES_ALLOWED in dki_readfile()). * misc function strchop() added to misc.c. zkt 0.62 -- 13. May 2005 * func dnssec-signer: Option -o added. Now it works a bit more like dnssec-signzone. * func strlist.c: prepstrlist and unprepstrlist functions get a second parameter for the delimiter. * bug fixed some typos and inaccurate usage of symbolic constants. Doing some housekeeping. zkt 0.61 -- 3. May 2005 * bug local config file will not be mentioned if -N switch is used. zkt 0.6 -- 1. May 2005 * doc dnssec-signer: man page added. * func dnssec-signer: Print out a warning message if ksk lifetime is exceeded. * func dnssec-signer: Remaining arguments will be interpreted as zone names (in_strarr () added). * func dnssec-signer: Option -D added. zkt 0.51 -- 8. April 2005 * func dnssec-signer: Option -N added. * func dnssec-signer: change of keystatus from pre-published to active resets timestamp of key, thus age of active key counts 0. * bug prepstrlist: resulting string was not terminated with '\0'. * bug dnssec-signer: do signing if there are additional keys, or the status of any key is changed (function check_keytimestamp). * func dnssec-zkt: -l option added. * func dnssec-zkt: -p flag defaults to on in key creation mode (-C). bind-9.6-ESV-R6/contrib/zkt/LICENSE000644 024064 023255 00000002750 11734112744 016605 0ustar00eachsweng000000 000000 Copyright (c) 2005 - 2008, Holger Zuleger HZnet.

Since v0.96, the dnssec-signer command is able to log all messages by itself. File and SYSLOG logging is supported. To enable the logging into a file channel, you have to specify the file or directory name via the commandline option -L (--logfile) or via the config file parameter "LogFile". LogFile: ""|""|"" (default is "") If a file is specified, than each run of dnssec-signer will append the messages to that file. If a directory is specified, than a file with a name of zkt-+log" will be created on each dnssec-signer run. Since v1.0 per domain logging is possible. If the parameter "LogDomainDir:" is not empty, than the domain specific messages are written to a separate log file with a name like "zkt-+log" in the directory specified by the parameter. If "LogDomainDir:" is set to ".", then the logfile will be created in the domain directory of the zone. Logging into the syslog channel could be enabled via the config file parameter "SyslogFacility". SyslogFacility: NONE|USER|DAEMON|LOCAL0|..|LOCAL7 (default is USER) For both channels, the log level could be set to one of six log levels: LG_FATAL, LG_ERROR, LG_WARNING LB_NOTICE, LG_INFO, LG_DEBUG The loglevel is settable via the config file parameter : SyslogLevel: FATAL|ERROR|WARNING|NOTICE|INFO|DEBUG (default is ERROR) and LogLevel: FATAL|ERROR|WARNING|NOTICE|INFO|DEBUG (default is NOTICE) All the log parameters are settable on the commandline via the generic option -O "optstring" (--config-option="optstring"). A verbose message output to stdout could be achieved by the commandline option -v (or -v -v). If you like to have this verbose messages also logged with a level of LG_DEBUG you should enable this by setting the config file option "VerboseLog" to a value of 1 or 2. Current logging messages: LG_FATAL: Not all of the fatal errors are logged (e.g.: config file or command line option fatal errors are not logged) LG_ERROR: All error messages will be logged LG_WARNING: KSK lifetime expiration LG_NOTICE: Start and stop of dnssec-signer Re-signing events Key rollover events KSK key generation and revoking Zone reload resp. freeze/thaw of dynamic zone LG_INFO: Currently none planned: Mesages for key generation and key status change (e.g.: pre-publish -> activate; revoked -> removed etc.) LG_DEBUG: all "verbose" (-v) and "very verbose" (-v -v) messages Some recomended and useful logging settings - The default setting LogFile: "" SyslogFacility: USER SyslogLevel: NOTICE VerboseLog: 0 - Setting as in version v0.95 LogFile: "zkt-error.log" # or a directory for separate logfiles LogLevel: ERROR SyslogFacility: NONE VerboseLog: 0 - Setting as in previous versions LogFile: "" SyslogFacility: NONE VerboseLog: 0 - Recommended setting for normal usage LogFile: "zkt.log" # or a directory for separate logfiles LogLevel: ERROR SyslogFacility: USER SyslogLevel: NOTICE VerboseLog: 0 - Recommended setting for debugging LogFile: "zkt.log" # or a directory for separate logfiles LogLevel: DEBUG SyslogFacility: USER SyslogLevel: NOTICE VerboseLog: 2 bind-9.6-ESV-R6/contrib/zkt/TODO000644 024064 023255 00000003225 11734112744 016266 0ustar00eachsweng000000 000000 TODO list as of zkt-0.99 general: Renaming to zkt-? and split of the functions of dnssec-zkt to separate commands Fixed in zkt-1.0 (zkt-conf command) dnssec-zkt: feat option to specify the key age as remaining lifetime (Option -i inverse age ?). dnssec-signer: bug Distribute_Cmd wouldn't work properly on dynamic zones (missing freeze, thaw; copy Keyfiles instead of signed zone file) bug Automatic KSK rollover of dynamic zones will only work if the parent uses the standard name for the signed zonefile (zonefile.db.signed). bug Phase3 of manual ksk rollover do not trigger a resigning of the zone (Key removal is not recognized by dosigning () function ) bug There is no online checking of the key material by design. The signer command checks the status of the key as they are represented in the file system and not in the zone. The dnssec maintainer is responsible for the lifeliness of the data in the hosted domain. In other words: It's highly recommended to use the option -r when you use zkt-signer on a production zone. Then the time of propagation is (more or less) equal to the timestamp of the zone.db.signed file. bug The max_TTL parameter should be set to the value found in the zone. A mechanism for setting up a dnssec.conf file for the zone specific TTL values is needed. Fixed in zkt-1.0 (zkt-conf command) zkt-conf: port Option -C (compability) to create older config files misc Change syntax of config parameters to a more uniq form (e.g. no "_" char) zkt-rollover: feat New command to roll keys independent of zone signing (Usefull for dynamic zones managed by BIND9.7) dki: feat Use dynamic memory for dname in dki_t bind-9.6-ESV-R6/contrib/zkt/config.h.in000644 024064 023255 00000013462 11734112744 017625 0ustar00eachsweng000000 000000 /* config.h.in.
