BIND help

[Sp00n]

Morning chaps and chapettes,

I have an issue with my BIND server in that it doesn't seem to be serving up DNS queries for anything that's pointing at it, this suddenly seemed to stop yesterday and I can't see any reason for it, all communication to and from the box seems fine and it seems to lookup against itself just fine.

Request from another server:

host google.com mydns.server.com
Using domain server:
Name: dlx36245
Address: 95.130.74.165#53
Aliases:

Request from BIND server to itself:

host google.com 127.0.0.1
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases:

google.com has address 173.194.34.174
google.com has address 173.194.34.160
google.com has address 173.194.34.161
google.com has address 173.194.34.162
google.com has address 173.194.34.163
google.com has address 173.194.34.164
google.com has address 173.194.34.165
google.com has address 173.194.34.166
google.com has address 173.194.34.167
google.com has address 173.194.34.168
google.com has address 173.194.34.169
google.com mail is handled by 30 alt2.aspmx.l.google.com.
google.com mail is handled by 40 alt3.aspmx.l.google.com.
google.com mail is handled by 50 alt4.aspmx.l.google.com.
google.com mail is handled by 10 aspmx.l.google.com.
google.com mail is handled by 20 alt1.aspmx.l.google.com.

So the lookups do appear to be working, just not for anything other than itself.

Am I missing something obvious?

Have you changed anything in iptables that could be preventing access to port 53? maybe try an nmap and see what it throws up.

 

[Sp00n]

I can telnet to 53 fine o the offending server, but I did also try turning off iptables on both servers as a precaution but no change.

Anything in your /etc/named.conf to block non-local lookups? ACL's or listening interface?
