What is a Mac Address?

In this example I will show you how to find your mac address in Ubuntu. This command should work any any terminal. Some distributions of linux you may need to be logged in as SU to see this information.

 

Open a terminal window

 

 

 

 

 

 

 

Type ifconfig -a

The -a at the end of the command will show you all connections even if it is down.

Next to each connection you should see your Mac Address. In the image below I underlined the Mac Address as well as a few of the connections. .
