[wplug] Home Server Follies

[Pete Butler]

Hello.

I've been using a Linux box as the gateway/firewall server on my home 
network -- the Linux box gets the cable modem, all the other machines in my 
home use it as the gateway.

I had it set up to run with Comcast, but my wife and I just moved, and 
wound up having to switch to Adelphia.  It worked fine for a few days, but 
spontaneously conked out on me yesterday.  My theory for what happened goes 
like this:

The problem seems to be DNS-related; I can't get any names to 
resolve.  Comcast required that I manually enter the addresses for the DNS 
servers, where Adelphia wants me to get them via DHCP.  I'm still set to 
look at Comcast's DNS servers, but somebody at Comcast finally flipped a 
switch telling me to stop freeloading and look elsewhere.

So, my question is, what do I need to do to reconfigure my Linux server to 
be dynamically picking up the DNS settings off DHCP?

(And yes, I am quite certain it's a problem with my Linux server, not the 
network.  When I plug the cable modem directly into the Win2K laptop I'm 
using right now, I can get online.  This isn't a long-term solution, unless 
I want to use the laptop as the gateway, which I'm really not interested in 
doing.)

Thanks for any help or advice you can offer, even if it's just an RTFM with 
the location of the appropriate FM.
