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 9.3.0
|
|
|
|
BIND 9.3.0 has a number of new features over 9.2,
|
|
including:
|
|
|
|
DNSSEC is now DS based.
|
|
See 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 NT/2000.
|
|
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 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
|
|
Windows NT/W2K
|
|
|
|
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
|
|
UnixWare 7.1.1
|
|
HP-UX 10.20
|
|
BSD/OS 4.2
|
|
Mac OS X 10.1
|
|
|
|
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)
|
|
|
|
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, 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).
|
|
|
|
* 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.
|
|
|
|
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.
|
|
|
