Find Your MAC address in Linux (Gnome 2, Gnome 3, and Unity)

What is a MAC Address?


 

You can think of a MAC address as a serial number for your network card. It is a unique six two-digits hexadecimal numbers separated by colons. It is used for routing traffic on a network.

 

In this example I will show you how to find your MAC in Ubuntu with gnome 2 and Unity and Gnome 3 on Arch Linux. These steps should apply to just about any linux distribution. The only difference is how you launch the terminal.There are a few linux distros that require you to issue the commands as the root or super user.
