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. BIND 9.3.6 BIND 9.3.6 is a maintenance release, containing fixes for a number of bugs in previous releases. The major change since 9.3.5 is query port randomization, to improve resilience against cache poisoning attacks. BIND 9.3.2 BIND 9.3.2 is a maintenance release, containing fixes for a number of bugs in 9.3.1. libbind: corresponds to that from BIND 8.4.7-REL.	Known Issues:	The following INSIST can be triggered with DNSSEC enabled. resolver.c:762: INSIST(result != 0 || dns_rdataset_isassociated(event->rdataset) || fctx->type == ((dns_rdatatype_t)dns_rdatatype_any) || fctx->type == ((dns_rdatatype_t)dns_rdatatype_rrsig)) failed	We are still trying to isolate the cause. If you have core	dump please send a bug report to bind9-bugs@isc.org with	the location of the core, named executable and OS details.	Note: contrib/nanny contains a perl script to restart named	in the event of a INSIST/REQUIRE/ENSURE failure. BIND 9.3.1 BIND 9.3.1 is a maintenance release, containing fixes for a number of bugs in 9.3.0. libbind: corresponds to that from BIND 8.4.6-REL. 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.	For a detailed list of user-visible changes from	previous releases, see the CHANGES file. 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	FreeBSD 4.10, 5.2.1	HP-UX 11.11	NetBSD 1.5	Slackware Linux 8.1	Solaris 8, 9, 9 (x86)	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.	Additionally, we have unverified reports of success building	previous versions of BIND 9 from users of the following systems:	AIX 5L	SuSE Linux 7.0	Slackware Linux 7.x, 8.0 Red Hat Linux 7.1	Debian GNU/Linux 2.2 and 3.0	Mandrake 8.1	OpenBSD 2.6, 2.8, 2.9, 3.1, 3.6, 3.8	UnixWare 7.1.1	HP-UX 10.20	BSD/OS 4.2	Mac OS X 10.1, 10.3.8	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	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 <unistd.h>) 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".	To build libbind (the BIND 8 resolver library), specify	"--enable-libbind" on the configure command line.	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.	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.
