local dns server

Hi,

I'm currently using my rh 9 linux box as a router/firewall/network server
etc... I'm wondering about making it run a DNS Server, the idea being it'll
cache my dns queries, so for pages i visit often it wont have to go to my
isp's dns. (Reason being that my isp's dns is down at the moment so it would
protect me from that yes? )

How do i do that?

Thanks for any suggestions/help!!

Cheers,
Dam

Install the caching nameserver package (if you have a choice, use bind9
rather than bind8). Set named.conf to only listen-on and allow-query for
loopback and local IP ranges to minimize public exposure if any bind
exploits develop:

listen-on port 53 { 127/8; 192.168/16; };
allow-query { 127/8; 192.168/16; };

Then read the DNS howto and try to set up forward and reverse zones for
your LAN using zone files for localhost and 0.0.127.in-addr.arpa as
examples in case something is slightly different.

Either put notify no; in your main options {}; section, or where you
specify any private zone files in named.conf.
