Change your Network Card MAC Address on Ubuntu

There are a lot of reasons you might want to manually set your MAC address for your connection card.

I won’t ask you what your reason is.

To change this setting, we’ll need to edit the /etc/web connection/interfaces file.

you could choose to use a different editor if you’d like.

sudo gedit /etc/web link/interfaces

You should see the line for your web link interface, which is usually eth0.

sudo /etc/init.d/networking restart

You will need to restart networking or reboot to take effect.
