Finding a Hardware Address (Linux)
the following command should work
if that's not working, maybe it's not in your path, try
or find it in your path. Try
if you have iproute2 (debian actually calls it iproute) installed, then
ip addr list
will work as well
In either case you'll have to figure out which is your wireless (perhaps with dmesg or lspci) and which is your wired connection if you have more than one nic, but that's not usually hard -- the results contain more than the mac addresses too, but they're easily parseable to find what you're looking for.
If you have SuSE, open the YaST network card module and select "change" if you have already configured your device. Look in the device column. You should see something like eth-id- followed by your address.
