Malfunction on CentOS Bind DNS Server

[tim874536]

Hi all,

I have a problem this morning. It is about CentOS Directadmin DNS server.
This server works for over 4 months without DNS problem, however, the problem shows up this morning.

When I nslookup and set the server as the server IP, resolve one of the domain hosted in this server, the output is 13 root server e.g. (root) nameserver = H.ROOT-SERVERS.NET but not the domain IP.

I have ensured that all services are running, and I removed and reinstalled the bind, bind-libs and bind-utils.
It works now.

I would like to ask any brother knows what is the problem before?
Is it really problem caused by old version of bind?

Old bind 9.3.4-10.P1.el5
New bind 9.3.6-16.P1.el5

Thanks.

Check /var/log/messages for errors.

Post your dns server ip and a domain that is on it so someone can check it.

Did you try to restart the bind/named service?
What happened?

Maybe you were hit by this DoS bug: http://www.directadmin.com/forum/showthread.php?t=40869
