SGI Freeware: BIND 8.2.1

BIND-8.2.1: description + notes

This is the source portion of BIND version 8.2.1. Its companions are "doc" and "contrib" so you are probably not missing anything.
See the CHANGES file for a detailed listing of all changes. See the INSTALL file for information on building and installing BIND.
See the SUPPORT file for information on obtaining commercial support for ISC artifacts including BIND, INN, and DHCP.
SECURITY NOTE:
Solaris and other pre-4.4BSD kernels do not respect ownership or protections on UNIX-domain sockets. This means that the default path for the NDC control socket (/var/run/ndc) is such that any user (root or other) on such systems can issue any NDC command except "start" and "restart". The short term fix for this is to override the default path and put such control sockets into root- owned directories which do not permit non-root to r/w/x through them. The medium term fix is for BIND to enforce this requirement internally. The long term fix is for all kernels to upgrade to 4.4BSD semantics.
BIND 8.2.1 Highlights
Bug fixes, especially to DNSSEC, TSIG, IXFR, and selective forwarding. Portability improvements and lint removal. Use best SOA rather than first-better when selecting an AXFR master. $TTL now accepts symbolic time values (such as "$TTL 1h30m"). "ndc reload" now accepts a zone argument, for single-zone reloads. ndc is better behaved; is verbose or quiet when appropriate. event and error reporting improvements.
BIND 8.2 Highlights
RFC 2308 (Negative Caching) RFC 2181 (DNS Clarifications) RFC 2065 (DNS Security) TSIG (Transaction SIGnatures) support for multiple virtual name servers NDC uses a "control channel" now (no more signals) "Split DNS" via zone type "forward".
Many bug fixes Documentation improvements Performance enhancements
BIND 8.1.2 Highlights
Security fixes for a number of problems including:
An attacker could overwrite the stack if inverse query support was enabled.
A number of denial of service attacks where malformed packets could cause the server to crash.
The server was willing to answer queries on its forwarding sockets.
Several memory leaks have been plugged.
The server no longer panics if a periodic interface scan fails due to no file descriptors being available.
Updates to a number of ports. New ports for QNX, LynxOS, HP-UX 9.x, and HP MPE.
"files unlimited" now works as expected on systems where setting an infinite rlim_max for RLIMIT_NOFILE works.
Adding and deleting the same record in the same dynamic update no longer crashes the server.
If a dynamic update fails, rollback is now done in LIFO order instead of FIFO order.
Better behavior when priming of the root servers fails.
purge_zone() didn't work correctly for the root zone, allowing old data to persist after loading the zone.
Improved handling of oversized UDP packets.
All hosts on the also-notify list are now notified.
The meaning of the count returned by select() varies somewhat by operating system, and this could cause previous releases of the server to spin.
Per-host statistics may be disabled by specifying 'host-statistics no' in named.conf.
The maximum number of zones has been increased from 32768 to 65536.
query-source may specify an address and port that the server is already listening on. BIND 8.1.1 required that either the address or port be wild. E.g., you can now say:
listen-on port 53 { 10.0.0.1; }; query-source address 10.0.0.1 port 53;
The value of FD_SETSIZE to use may be specified.
Experimental -u (set user id), -g (set group id), and -t (chroot) command line options. See the INSTALL file for details.
BIND 8 Features
-> DNS Dynamic Updates (RFC 2136)
-> DNS Change Notification (RFC 1996)
-> Completely new configuration syntax
-> Flexible, categorized logging system
-> IP-address-based access control for queries, zone transfers, and updates that may be specified on a zone-by-zone basis
-> More efficient zone transfers
-> Improved performance for servers with thousands of zones
-> The server no longer forks for outbound zone transfers
-> Many bug fixes

To Support the Effort
Note that BIND is supported by the Internet Software Consortium, and although it is free for use and redistribution and incorporation into vendor products and export and anything else you can think of, it costs money to produce. That money comes from ISPs, hardware and software vendors, companies who make extensive use of the software, and generally kind hearted folk such as yourself.
The Internet Software Consortium has also commissioned a DHCP server implementation, has taken over official support/release of the INN system, and supports the Kerberos Version 5 effort at MIT. You can learn more about the ISC's goals and accomplishments from the web page at .
