DNS Zone Authority

Nodes will typically be set to use the master node as the DNS server. This is a good thing, because cobbler is managing the DNS server on the master node and it will get updated when adding and removing nodes.

However, you may want your organization's main DNS server to know about all of the DNS records inside the cluster. For this to occur, you want the main DNS server to zone-transfer from the master node of the cluster.

On master, in /etc/cobbler/named.template, allow zone transfers from the IP address of your main DNS server.

          allow-transfer  { 129.100.100.5; };

When making changes, you will need to update cobbler
