I've been training a member of staff in setting up cpanel servers and unfortunately in the basic setup on one server she entered the local resolver ip addresses instead of the nameservers hostnames. This means that all the DNS records on the server are incorrect - about 100. Can I just go into /var/named and use... replace "IN NS x.x.x.x." "IN NS ns1.hostname." -- * That wouldnt change the serial in the zone files though so how could I then force bind to update to the nameservers ?
