nsd users - Mar 2011 - failed to query a created zone

Hi,

I'm new to name server and nsd. I'm using nsd3 on Debian 5.

My problem is that I could not find what gives below error in nsd log file

[1300081686] nsd[2649]: error: can't bind the socket: Cannot assign 
requested address
[1300081698] nsd[2705]: error: can't bind the socket: Cannot assign 
requested address

My configuration was posted on lq forum a few days aago and can be 
viewed at -> 
http://www.linuxquestions.org/questions/linux-server-73/failed-to-query-a-zone-nsd3-868216/

Any thoughts and suggestions?

It would seem the configured IP address doesn't exist or you already
have a process listening on port 53 for the configured address. Check
wether you have, e.g. a BIND name server running already.
