the caching-nameserver package which is the root of the problem should
perhaps better be called 'only-caching-nameserver-and-nothing-else'. You
install it if you don't feel like configuring anything and want a local
caching nameserver on a desktop.
If you want to configure a server with DNS, then you DO NOT install
caching-nameserver, instead you setup bind by hand (or with a different
program GUI whatever) and you can configure it to host some zones and to
query others from the internet and to reply to some queries from local
hosts (local LAN) recursively and to only reply to hosted zone queries
from non-local hosts (rest of the Internet). Etc. IE. YOU DO NOT NEED THE
CACHING-NAMESERVER PACKAGE TO HAVE A CACHING NAMESERVER. The package is
only meant to simplify life on normal desktops.
Besides you shouldn't be running bind anyway... DJBDNS/TINYDNS/DNSCACHE
are much better anyway (although a little harder to setup in the first
place, once done they run and run and run like duracel or the energizer
bunny with no problems whatsoever).
Cheers,
MaZe.
