BIND – Configure master/slave zone

Published on Author gryzliLeave a comment

Below is some simple configuration for running DNS Master/Slave zone.

 

We assume the following IP configuration:

  • DNS Master : 192.168.1.1
  • DNS Slave : 192.168.1.2
  • DNS Zone: domain.com

 

Master Server Configuration

Master server’s named.conf must contain something like this:

view "external" {
        allow-transfer {none;};
        zone "." IN {
                type hint;
                file "named.ca";
        };
        include "/etc/named.rfc1912.zones";
        include "/etc/named.root.key";
        zone "domain.com" IN {
                type master; 
                file "domain.com.zone";
                allow-transfer {192.168.1.2;};
                notify yes;
                also-notify {192.168.1.2;};
        };
};

 

Slave Server Configuration

Slave server’s named.conf must contain something like that:

view "external"
{
        allow-transfer{none;};
        recursion no;

        zone "." IN {
                type hint;
                file "named.ca";
        };

        zone "domain.com" {
                type slave;
                file "/var/named/slaves/domain.com";
                masters {192.168.1.1;};
        };

        include "/etc/named.rfc1912.zones";
        include "/etc/named.root.key";
};
