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
|
|

BIND 9.7.0
|
|
|
|
BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
|
|
releases. Most are intended to simplify DNSSEC configuration.
|
|
|
|
New features include:
|
|
|
|
- Fully automatic signing of zones by "named".
|
|
- Simplified configuration of DNSSEC Lookaside Validation (DLV).
|
|
- Simplified configuration of Dynamic DNS, using the "ddns-confgen"
|
|
command line tool or the "local" update-policy option. (As a side
|
|
effect, this also makes it easier to configure automatic zone
|
|
re-signing.)
|
|
- New named option "attach-cache" that allows multiple views to
|
|
share a single cache.
|
|
- DNS rebinding attack prevention.
|
|
- New default values for dnssec-keygen parameters.
|
|
- Support for RFC 5011 automated trust anchor maintenance
|
|
- Smart signing: simplified tools for zone signing and key
|
|
maintenance.
|
|
- The "statistics-channels" option is now available on Windows.
|
|
- A new DNSSEC-aware libdns API for use by non-BIND9 applications
|
|
- On some platforms, named and other binaries can now print out
|
|
a stack backtrace on assertion failure, to aid in debugging.
|
|
- A "tools only" installation mode on Windows, which only installs
|
|
dig, host, nslookup and nsupdate.
|
|
- Improved PKCS#11 support, including Keyper support and explicit
|
|
OpenSSL engine selection.
|
|
|
|
Known issues in this release:
|
|
|
|
- In rare cases, DNSSEC validation can leak memory. When this
|
|
happens, it will cause an assertion failure when named exits,
|
|
but is otherwise harmless. A fix exists, but was too late for
|
|
this release; it will be included in BIND 9.7.1.
|
|
|
|
Compatibility notes:
|
|
|
|
- If you had built BIND 9.6 with any of ALLOW_NSEC3PARAM_UPDATE,
|
|
ALLOW_SECURE_TO_INSECURE or ALLOW_INSECURE_TO_SECURE defined, then
|
|
you should ensure that all changes that are in progress have
|
|
completed prior to upgrading to BIND 9.7. BIND 9.7 implements
|
|
those features in a way which is not backwards compatible.
|
|
|
|
- Prior releases had a bug which caused HMAC-SHA* keys with long
|
|
secrets to be used incorrectly. Fixing this bug means that older
|
|
versions of BIND 9 may fail to interoperate with this version
|
|
when using TSIG keys. If this occurs, the new "isc-hmac-fixup"
|
|
tool will convert a key with a long secret into a form that works
|
|
correctly with all versions of BIND 9. See the "isc-hmac-fixup"
|
|
man page for additional details.
|
|
|
|
- Revoking a DNSSEC key with "dnssec-revoke" changes its key ID.
|
|
It is possible for the new key ID to collide with that of a
|
|
different key. Newly generated keys will not have this problem,
|
|
as "dnssec-keygen" looks for potential collisions before
|
|
generating keys, but exercise caution if using key revokation
|
|
with keys that were generated by older versions of BIND 9.
|
|
See the Administrator's Reference Manual, section 4.10 ("Dynamic
|
|
Trust Anchor Management") for more details.
|
|
|
|
- A bug was fixed in which a key's scheduled inactivity date was
|
|
stored incorectly. Users who participated in the 9.7.0 BETA
|
|
test and had DNSSEC keys with scheduled inactivity dates will
|
|
need to reset those keys' dates using "dnssec-settime -I".
|
|
|
|
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:
|
|
|
|
COMPAQ Tru64 UNIX 5.1B
|
|
Fedora Core 6
|
|
FreeBSD 4.10, 5.2.1, 6.2
|
|
HP-UX 11.11
|
|
Mac OS X 10.5
|
|
NetBSD 3.x, 4.0-beta, 5.0-beta
|
|
OpenBSD 3.3 and up
|
|
Solaris 8, 9, 9 (x86), 10
|
|
Ubuntu 7.04, 7.10
|
|
Windows XP/2003/2008
|
|
|
|
NOTE: As of BIND 9.5.1, 9.4.3, and 9.3.6, older versions of
|
|
Windows, including Windows NT and Windows 2000, are no longer
|
|
supported.
|
|
|
|
We have recent reports from the user community that a supported
|
|
version of BIND will build and run on the following systems:
|
|
|
|
AIX 4.3, 5L
|
|
CentOS 4, 4.5, 5
|
|
Darwin 9.0.0d1/ARM
|
|
Debian 4
|
|
Fedora Core 5, 7
|
|
FreeBSD 6.1
|
|
HP-UX 11.23 PA
|
|
MacOS X 10.4, 10.5
|
|
Red Hat Enterprise Linux 4, 5
|
|
SCO OpenServer 5.0.6
|
|
Slackware 9, 10
|
|
SuSE 9, 10
|
|
|
|
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)
|
|
Disable dropping queries from particular well known ports.
|
|
-DNS_CLIENT_DROPPORT=0
|
|
Sibling glue checking in named-checkzone is enabled by default.
|
|
To disable the default check set. -DCHECK_SIBLING=0
|
|
named-checkzone checks out-of-zone addresses by default.
|
|
To disable this default set. -DCHECK_LOCAL=0
|
|
To create the default pid files in ${localstatedir}/run rather
|
|
than ${localstatedir}/run/{named,lwresd}/ set.
|
|
-DNS_RUN_PID_DIR=0
|
|
Enable workaround for Solaris kernel bug about /dev/poll
|
|
-DISC_SOCKET_USE_POLLWATCH=1
|
|
The watch timeout is also configurable, e.g.,
|
|
-DISC_SOCKET_POLLWATCH_TIMEOUT=20
|
|
|
|
LDFLAGS
|
|
Linker flags. Defaults to empty string.
|
|
|
|
The following need to be set when cross compiling.
|
|
|
|
BUILD_CC
|
|
The native C compiler.
|
|
BUILD_CFLAGS (optional)
|
|
BUILD_CPPFLAGS (optional)
|
|
Possible Settings:
|
|
-DNEED_OPTARG=1 (optarg is not declared in <unistd.h>)
|
|
BUILD_LDFLAGS (optional)
|
|
BUILD_LIBS (optional)
|
|
|
|
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".
|
|
|
|
On some platforms it is necessary to explictly request large
|
|
file support to handle files bigger than 2GB. This can be
|
|
done by "--enable-largefile" 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.
|
|
|
|
Support for the "fixed" rrset-order option can be enabled
|
|
or disabled by specifying "--enable-fixed-rrset" or
|
|
"--disable-fixed-rrset" on the configure command line.
|
|
The default is "disabled", to reduce memory footprint.
|
|
|
|
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).
|
|
|
|
Known compiler issues:
|
|
* 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.
|
|
* gcc-3.3.5 powerpc generates incorrect code at -02.
|
|
* Irix, MipsPRO 7.4.1m is known to cause problems.
|
|
|
|
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.
|
|
|
|
SunOS 4 requires "printf" to be installed to make the shared
|
|
libraries. sh-utils-1.16 provides a "printf" which compiles
|
|
on SunOS 4.

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.
