Having just starting using Ubuntu I have been needing to do some basic setup options to put my laptop on the network at the office. We use Mac Address based security and so I needed to find mine for the ethernet card.
Looking through all the administration options to find it was unsuccessful and it was definately not as obvious to find as I hoped. After trawling through the Ubuntu Forums and reading about 9 threads I found you simply need to go to Terminal (which is located under Applications>Accessories) and then type in ifconfig and press enter, and you will get a list of your hardware address for your network card.
