[NTLUG:Discuss] which one is eth0, and which one is eth1?

[m m]

Hi all:
I have two questions here, please help.

1. How do I know which card is eth0 and the other is eth1 physically? I 
guess that it is based on the motherboard's slot order? right?

2. when I type ifconfig, it only shown the information of lo and eth0, but 
if I type ifconfig eth1, it will show eth1’s information? What is wrong on 
it?

TIA

jc
