The easiest way to find your ethernet hardware address in a *nix like operating system is to use the ifconfig command. Open up a terminal or shell window and run ifconfig. Example outputs are below.

You may need to specify the entire path to ifconfig to get the information you are looking for. If you can not find ifconfig try "locate ifconfig". The examples below have the MAC address highlighted. Be sure to record the MAC address of your ethernet interface. The loopback ("lo") interface is a virtual internal address that cannot be bound to an IP.

Linux

bash% /sbin/ifconfig -a
