mapping physical device to eth0

[qin__23]

Hi, I'm running knoppix on my HP nc8000 laptop.

How can I tell what physical connection eth0 refers to?
The problem is one of the programs I am using in knoppix can only us eth0, so it will attempt to use eth0 every single time.
Unfortunately, I have no idea if eth0 is actually the wired connection (which is what I want).

Basically, I need to be able to tell which physical network devices are mapped to eth0, eth1, etc.
From there, I will then disable the modules that I do not want (wireless, etc.).
Any ideas?
Thanks.

Have you tried ifconfig ? What program is it that defaults to eth0 and can't use other devices?

[qin__23]

Yes, I tried ifconfig.

I tried:
ifconfig -alias eth0
ifconfig alias eth0
ifconfig eth0 alias
ifconfig etho -alias

and none of them worked, replying with: "eth0: Host name lookup failure".

I also tried ifconfig eth0 down, but the program still attempted to use eth0.
The program is a closed-source software used to talk to a network attached device.

Is the structure of my command incorrect?
Is there a command to say swap eth0 for eth1?

use mii-tool or ethttool command to find out to which ethernet port the cable is connected to. The output will tell you which port is being picked up as eth0 , wire accordingly.

Will do. Thanks.
