freebsd-nq/contrib/bind/README

This is the source portion of BIND version 8.2.3-T2B.  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 8.2.2 patchlevel 5 Highlights

	Bug in named-xfer (from patchlevel 4).
	Portability to IPv6 versions of FreeBSD, OpenBSD, NetBSD.
	Portability improvements (A/UX, AIX, IRIX, NetBSD, SCO, MPE/IX, NT).
	"also-notify" option could cause memory allocation errors.
	IXFR improvements (though client-side is still disabled).
	Contributed software upgraded (including TIS's "dns_signer").
	Several latent denial-of-service bugs fixed (from audits, not abuse).
	New "make noesw" top-level target for removing encumbered components.

BIND 8.2.2 Highlights

	Interoperability with MS-Win2K has been improved.                     
	Server-side IXFR is now known to work even under high load.                 
	Support for Windows/NT (thanks to BayNetworks).
	More fixes, especially to DNSSEC, TSIG, IXFR, and selective forwarding.
	More portability improvements and lint removal (A/UX 3.1.1, SCO 5.0).
	Better NOTIFY behaviour, especially with large update volume.
	Better UPDATE handling, including SRV RR support and RFC compliance.
	Fix for "ndc reload ZONENAME" (specific zone reload) problems.
	Fix for round robin when multiple CNAMEs are in use.
	New "min-roots" (MINROOTS) and "serial-queries" (MAXQSERIAL) options.
	Log files are no longer auto-rotated every time the server starts up.
	New "ndc reconfig" command only finds new/deleted zones, no stat()ing.
	New global options for "transfer-source" and "also-notify".
	$GENERATE now supports more record types, and options.


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.

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 has supported the Kerberos Version 5 effort at MIT.  You
	can learn more about the ISC's goals and accomplishments from the web
	page at <URL:http://www.isc.org/>.
