¿Como configuro servidor DNS?

Hola.

Mira:

[root@bestiaparda ~]# urpmq -i bind
Name        : bind
Version     : 9.6.0
Release     : 5.1mdv2009.1
Group       : System/Servers
Size        : 14191570                     Architecture: x86_64
Source RPM  : bind-9.6.0-5.1mdv2009.1.src.rpm

Summary     : A DNS (Domain Name System) server
Description :
BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(domain Name System) protocols. BIND includes a DNS server (named),
which resolves host names to IP addresses, and a resolver library
(routines for applications to use when interfacing with DNS).  A DNS
server allows clients to name resources or objects and share the
information with other network machines.  The named DNS server can be
used on workstations as a caching name server, but is generally only
needed on one machine for an entire network.  Note that the
configuration files for making BIND act as a simple caching nameserver
are included in the caching-nameserver package.

Install the bind package if you need a DNS server for your network.  If
you want bind to act a caching name server, you will also need to install
the caching-nameserver package.

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/dev/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.

Build Options:
--without sdb_ldap    Build without ldap simple database support (enabled
                      per default)
--with sdb_mysql      Build with MySQL database support (disables ldap
                      support, it's either way.)
--with geoip          Build with GeoIP support (disabled per default)

Update importance   : security
Reason for update   :
A vulnerability has been found and corrected in ISC BIND:

The dns_db_findrdataset function in db.c in named in ISC BIND 9.4
before 9.4.3-P3, 9.5 before 9.5.1-P3, and 9.6 before 9.6.1-P1, when
configured as a master server, allows remote attackers to cause
a denial of service (assertion failure and daemon exit) via an ANY
record in the prerequisite section of a crafted dynamic update message,
as exploited in the wild in July 2009 (CVE-2009-0696).

This update provides fixes for this vulnerability.

¿Tienes configurados los repositorios?

Sin configurar los repositorios no puedes usarlos.

¿Y para qué quieres tener los puertos del correo abiertos para un servidor DNS?

Atentamente,
El BOFH anteriormente conocido como vfmmeo. No había nadie mejor disponible.

Sígueme o aparta.

Espero que hallas comprado esa Powerpack: http://blogdrake.net/descarga-mandriva-powerpack
