I'm sorry, but in my earlier message, I neglected to fully explain my
setup. I can't afford $50 for a router (the holidays etc.), so I have
to do it the hard way, at least for now. I'm a writer, and I want to
be able to work on my own computer during the holidays without
constantly being asked by my family to use the internet.
Ok, here's my setup: I have broadband over a surfboard modem from Cox
cable. I have an ethernet card (D-link) that I just picked up, and a
crossover cable that connects the two computers via this card, to
another, identical one on the linux box. I've had this working using
Win XP (very easily), but I really don't want to go back if I can
avoid it.
Here's the results of ifconfig (I can't make heads or tails of it-
which one is my incoming internet connection? ):
fwe0: flags=108802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
ether 02:e0:18:11:a5:2b

Anyway, thank you all very much, I really appreciate the help.
