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 9.2

        BIND 9.2.0a1 is the first alpha release of BIND 9.2.0.
        It includes 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" statememnts, 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. It is not built by default, and may not build
            on all supported platforms yet.

        This distribution already 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 9.2 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 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.

                --with-libtool does not work on AIX.

        A bug in the Windows 2000 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:

                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
                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.x
                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.

        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.

        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.

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.
