Perfect,
Second followup question.
I'm watching requests go from my machine to my ISP's DNS server and calling
on ports ranging anywhere from 1039 to 1108 (recently). If I close down
those ports I can't seem to get a response from an 'nslookup' and email
stops arriving too.
Why would my RH 6.2 machine call out on ports other than 53 or 42 which seem
to be the ports for nameservers?
The longer I watch it the higher the calling number goes and it seems to
call sometimes on UDP and other times on TCP.
Sorry if this is ignorant, I'm new to firewalls.

Hi,
Does anyone know of a document that describes what ports are related to what
services?
I'm noticing that DNS seems to call my machine on ports anywhere from 1039
to
1049 (or thereabouts), and its completely unpredictable.
So, I was wondering if anyone knew what ports should be left open for a
server
which which generally be running http and smtp ?
