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 (A6, DNAME, etc.) Bitstring Labels 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 BIND 9.1.1rc4 BIND 9.1.1rc4 is a release candidate for BIND 9.1.1. It contains fixes for a number of bugs in BIND 9.1.1rc3 but no new features. Features introduced in 9.1.0 included: - Many BIND 8 features previously unimplemented in BIND 9, including domain-specific forwarding, the $GENERATE master file directive, and the "blackhole", "dialup", and "sortlist" options - Forwarding of dynamic update requests; this is enabled by the "allow-update-forwarding" option - A new, simplified database interface and a number of sample drivers based on it; see doc/misc/sdb for details - Support for building single-threaded servers for environments that do not supply POSIX threads - New configuration options: "min-refresh-time", "max-refresh-time", "min-retry-time", "max-retry-time", "additional-from-auth", "additional-from-cache", "notify explicit" - Faster lookups, particularly in large zones. BIND 9.1 also includes experimental implementations of a number of DNS protocols extensions still under development in the IETF. These include transparent processing of unknown RR types and use of the EDNS "DNSSEC OK" bit to explicitly enable DNSSEC processing in responses. Cryptographic operations are now based on the OpenSSL library instead of DNSsafe. BIND 9.1 is primarily a name server software distribution. In addition to the name server, it 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 still 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 9.1 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 wildcard records in secure zones. When acting as a caching server, BIND 9.1 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. There are known problems with thread signal handling under Solaris 2.6 and BSD/OS. We recommend disabling threads with "configure --disable-threads" on these platforms. 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. --with-libtool does not work on AIX. 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: AIX 4.3 COMPAQ Tru64 UNIX 4.0D COMPAQ Tru64 UNIX 5 (with IPv6 EAK) FreeBSD 3.4-STABLE, 3.5, 4.0, 4.1 HP-UX 11 IRIX64 6.5 NetBSD 1.5 (with unproven-pthreads-0.17) Red Hat Linux 6.0, 6.1, 6.2, 7.0 Solaris 2.6, 7, 8 Additionally, we have unverified reports of success building previous versions of BIND 9 from users of the following systems: Slackware Linux 7.0 with 2.4.0-test6 kernel and glibc 2.1.3 Slackware Linux 7.0.1 with glibc 2.1.3 OpenBSD 2.6, 2.8, -current UnixWare 7.1.1 HP-UX 10.20 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. To build shared libraries, specify "--with-libtool" on the configure command line. To build without multithreading, specify "--disable-threads" on the configure command line. 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. To see additional configure options, run "configure --help". "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". 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. Building with gcc is not supported, unless gcc is the vendor's usual compiler (e.g. the various BSD systems, Linux). 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. Linux systems do not provide useful core dumps for multithreaded programs unless the kernel patch in contrib/linux/coredump-patch has been applied. We recommend all Linux users to install this patch so that any server crashes can be properly diagnosed. 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 under the doc/man directory. In particular, the command line options of "named" are documented in doc/man/bind/named.8. There is now also a set of man pages for the lwres library. The man pages are currently not installed automatically by "make install". If you are upgrading from BIND 8, please read the migration notes in doc/misc/migration.
