Finally! Thank you Jan. Some of the suggestions are pretty convenient, like dmesg, which should give you the vendor details, but that would break down if they are the same vendor. And considering this is the absolute correct way, some of the other suggestions are a little "long way around" types.
The MAC address always exists on Ethernet cards. It should be visible from the outside of your computer, however, some have it printed on the card itself. If the latter is the case, I would try one of the simpler suggestions, as applicable to your situation.

Quite a bunch of interesting replies :-) Here is mine: Each and every ethernet card has its own unique MAC number, this number usually is written on the retail box and/or the card itself. You can get this number e.g. using ip(8) of the iproute package (The MAC is 00:04:AC:24:67:7D here): | % ip l l eth0 | 2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 | link/ether 00:04:ac:24:67:7d brd ff:ff:ff:ff:ff:ff You may or may not find this useful: | nameif (8) - name network interfaces based on MAC addresses HTH. -- Jan Minar "Please don't CC me, I'm subscribed." x 9
