DNS Server

Hi

I recently bought Virtualmin Pro. The first time we loaded it we made a mess of it and nothing seemed to work, we tried all sorts of things and got some advice from here but we were getting all sorts of errors.

We did a clean install again and this time it installed bueatifully and have not had an error message, we are very pleased with the installation.

I have got everything setup but my DNS Server does not seem to be working. I have created a master Virtual Server and edited the records in Bind DNS and as far as I can tell it is all set up correctly.

I have had my registrar create the following host records
ns1.cybernamixqld.com - 60.234.78.35
ns2.cybernamixqld.com - 60.234.78.36

I have setup the eth0 as IP Address 60.234.78.35 and eth0 (virtual) as 60.234.78.36.

I can access the server via both IP Addresses.

The server is called sv1.cybernamixqld.com in Hostname and DNS Client - Network Configuration

This is the records file from cybernamixqld.com

I know it is propably something I have missed etc and I appreciatte anyones time who can assist me as I am getting frustrated.

Thanks again
Greg

Thanks

Yes BIND is definettly running.

I ran the command locally and got

sv1:~# host cybernamixqld.com 60.234.78.35
Using domain server:
Name: 60.234.78.35
Address: 60.234.78.35#53
Aliases:

cybernamixqld.com has address 60.234.78.35
cybernamixqld.com mail is handled by 5 mail.cybernamixqld.com.

So it looks like a firewall problem.

I will talk to the firewall administrator and see if he can fix it

Thanks again
Greg

Hi
We are having trouble getting the firewall to not block it.

We have put in the following but it still seems blocked.

ACCEPT net dmz:60.234.78.35 tcp 53

Can you tell me what we should set?

Cheers
Greg

Don’t worry, we have fixed it.

Thanks again for your great support.

Nice support request, Greg. Everything I need to know to be able to help is right there. (It’s rare enough to be worth commenting on.)

OK, so, troubleshooting DNS goes like this:

Is the registrar serving the right name servers?

$ whois cybernamixqld.com

Domain servers in listed order:
NS1.CYBERNAMIXQLD.COM 60.234.78.35
NS2.CYBERNAMIXQLD.COM 60.234.78.36

Yes, awesome. Are the name servers serving the right data:

$ host cybernamixqld.com 60.234.78.35
;; connection timed out; no servers could be reached

Hmmm…no. So there’s a problem.

Check to see if BIND is running:

ps auxc | grep named

Got a firewall blocking port 53? If it’s behind a NATting firewall, is that port being forwarded?

Does it work locally? (i.e. if you run the host command on the system itself.)
