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

BIND 9.1.3
|
|
|
|
BIND 9.1.3 is a maintenance release, containing fixes for
|
|
a number of bugs in 9.1.2 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.
|
|
|
|
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 (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:
|
|
|
|
AIX 5L
|
|
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
|
|
Red Hat Linux 7.1
|
|
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.
|
|
|
|
"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.
|
|
|
|
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. If you are upgrading from
|
|
BIND 4, read doc/misc/migration-4to9.
