I have two (diffrent kind) of ethernet cards in my ubuntu box. The other one is connected to my adsl box and the other one is connected to my good comp with a crossover cable. I did dmesg | grep eth and I got this: http://www.rafb.net/paste/results/VfU0rp71.html

What does that mean and what do I have to do to get the other card to fetch the IP from a dhcp server (the adsl) and the other one to have a static ip??

If I understand you, it sounds like you have a ADSL modem Is that correct?

You have two computers, one with two ethernet cards, where 1 is connected to the ADSL modem, the second ethernet card connects to If I understand your configuration, the connection between the comp with two ethernet cards and your "good comp" needs to be a separate sub-net. This can be any private class A class B or class C private sub-net. For class C 192.168.x.x will do. If I were you, define teh IP addresses for the two interfaces on teh direct cable. Onnce done, try pinging. That will work if they are in the same sub-net. Next you have to get the private sub-net to talk to the outside world. You need a routing function.

I have never done this kind of setup, but lots of others have. I think you need to setup iptables. Have a look around the board, and in the tutorials.

The easiest way is to buy a router and plug all your boxes into it; but that costs a few bucks... I have seen four port routers for as little as $49.00. Have a look around.
