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

BIND 9.2
|
|
|
|
This is a snapshot of the development source tree that
|
|
will become BIND 9.2. Bind 9.2 will have a number of
|
|
new features over 9.1, including:
|
|
|
|
- The ability to automatically convert RFC1886-style
|
|
recursive lookup requests into RFC2874-style lookups,
|
|
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.
|
|
|
|
An IPv6 capable stub resolver based on the BIND 8 resolver
|
|
code base and fully backwards compatible with existing BIND 8
|
|
based resolvers is being developed and will be integrated into
|
|
the BIND 9 distribution when completed.
|
|
|
|
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.
|
|
|
|
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 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.
|
|
|
|

|
|
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.
