Going from slave server to master server

[kcdworks]

I have a server that was originally set up as a slave server, but it now needs to be a master server. What is the easiest way to do this? The NOC recommended simply removing the master dns server in the &Edit Setup& section, but now I am getting ndc connection refused messages when making any DNS changes. I ran the following commands to track down the problem:

ndc reload
tail /var/log/messages

And got this back:

any help appreciated.

( I also tried making a backup of named.conf and removing all accounts that were on the master server and changing the localhost zone back to master, to no avail.)

If I'm not mistaken, you can only have allow-update substatements in master zones (type master and not type slave). That's also what the error messages say anyway.

I didn't know Cpanel set up dynamic updates.

If that were true, then I'd be getting errors on the previous master server (which is still up and running) because it has the same &auto-update& lines in it.

That's why i'm stuck.

Hmm, can we see the output of this:
# grep &0.0.127.in-addr.arpa& -A4 /etc/named.conf
in both servers?

What's the localhost zone for?

 

[itf]

modify /etc/named.conf

you have to remove &masters& line (master server IP address lines) in zone blocks and also change &type& statement to &master& also remove allow-update line in both servers (if applicable)

if you still have a problem run
/scripts/fixnamed
/scripts/fixndc
is a root SSH session

It seems that it's finally working. Thanks for the help everyone ... I simply restored the backup I made before I started, made all the changes again, and it worked ... so I guess that's it.
