===== Basic DNS Setup =====

Install bind9 and configured the server to run in a chroot as per [[chrooted_dns|here]].

On your primary names server, edit /var/lib/named/etc/bind/named.conf.local

  server <123.134.145.5> { provide-ixfr yes; };      #your first backup name server's IP
  server <123.134.145.6> { provide-ixfr yes; };      #your nth backup names server's IP
  
  zone "145.134.123.in-addr.arpa" in { type master; file "pz/123.134.145"; };     #Your IP range for reverse lookups
  zone "domain.tld" in { type master; file "pz/domain.tld"; };        # zone file for a domain

Create a pz directory in whatever directory is specified in /var/lib/named/etc/bind/named.conf.options:

  directory "/var/cache/bind";

Remember, bind is chrooted into /var/lib/named/, so:

  mkdir /var/lib/named/var/cache/bind/pz

Then create your domain and reverse lookup files:

  touch var/lib/named/var/cache/bind/pz/domain.tld
  touch var/lib/named/var/cache/bind/pz/123.134.145.in.addr.arpa

Set up your reverse lookups file for the IP range you gave by editing the arpa file:

  $TTL 3600
  @               IN      SOA     ns0.domain.tld.    hostmaster.domain.tld. (
                          2006091001 ; serial
                          4h ; refresh
                          1h ; retry
                          1w ; expire
                          1h ; default_ttl
                          )
  
                  IN      NS      ns0.domain.tld.
                  IN      NS      ns1.domain.tld.
                  IN      NS      ns2.domain.tld.
  
  4      IN      PTR     ns0.domain.tld.  
  5      IN      PTR     ns1.domain.tld.
  6      IN      PTR     ns2.domain.tld.
  10     IN      PTR     mail.domain.tld
  11     IN      PTR     mail2.domain.tld
  65     IN      PTR     www.domain.tld.


Now set up your domain's file:

  $TTL 3600
    @               IN      SOA     ns0.domain.tld.    hostmaster.domain.tld. (
                          2006122101 ; serial
                          4h ; refresh
                          1h ; retry
                          1w ; expire
                          1h ; default_ttl
                          )
  
                  IN      TXT     "MyTextHere"
                  IN      TXT     "v=spf1 ip4:123.134.145.10 -all"
                  IN      NS      ns0.domain.tld.
                  IN      NS      ns1.domain.tld.
                  IN      NS      ns2.domain.tld.
                  IN      MX      10      mail.domain.tld.
                  IN      MX      20      mail2.domain.tld.
                  IN      A       123.134.145.65
  
  localhost       IN      A       127.0.0.1
  ns0             IN      A       123.134.145.4
                  IN      MX      10      mail.domain.tld.
                  IN      MX      10      mail2.domain.tld.
  ns1             IN      A       123.134.145.5
                  IN      MX      10      mail.domain.tld.
                  IN      MX      10      mail2.domain.tld.
  ns2             IN      A       123.134.145.6
                  IN      MX      10      mail.domain.tld.
                  IN      MX      10      mail2.domain.tld.
  www             IN      A       123.134.145.65
                  IN      MX      10      mail.domain.tld.
                  IN      MX      10      mail2.domain.tld.
  mail            IN      A       123.134.145.10
                  IN      MX      10      mail.domain.tld.
                  IN      MX      10      mail2.domain.tld.
  mail2           IN      A       123.134.145.11
                  IN      MX      10      mail.domain.tld.
                  IN      MX      10      mail2.domain.tld.

Restart the name services:

  /etc/init.d/bind9 restart

On your backup name server(s), edit /var/lib/named/etc/bind/named.conf.local
