Hi all,
I've setup a DNS server (Bind/Named of course) to resolve several web servers I host. How can I restrict on my DNS server queries that only apply to my domains names and not any ? (in others words, how to disable my server to be an open-relay dns server ?)
Any help would be appreciated

You need to turn off the "recursion" setting. From a DNS server I maintain, in the "options" section at the top I have:
allow-recursion { none; };
You can be more flexible there, for example allowing recursion for your internal LAN clients but not the outer world.
Cheers,
I do this to limit queries to my LAN only.
In the options section:
allow-query { localhost;192.168.2.0/24; }; recursion yes;
