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
