In this tip, we will see two ways for changing the MAC address either using a few terminal commands or simply from the network manager under Ubuntu 13.04/12.10 or older. For Linux Mint users, you can use the terminal way to change the MAC address.

Getting Started

   1. Method 1 (CLI)

Turn off your network manager using this command from the terminal:

sudo ifconfig eth0 down
Replace eth0 with your own network adapter name (eth1wlan0, etc.). Now change your MAC address with this command:

sudo ifconfig eth0 hw ether  <NEW MAC ADDRESS>

Here is an example:

sudo ifconfig eth0 hw ether  08:00:25:de:40:df

Turn on the network manager:

sudo  ifconfig eth0 up

   2. Method 2 (GUI)

Under Ubuntu Unity, open the NetworkManager indicator menu and select "Edit Connections":

Select your internet connection and click "Edit":

Under the "Ethernet" tab, you can easily change your MAC address in the appropriate text box:

Click "Save" to confirm, then restart the network manager. You can also change the MAC address using MACCHANGER.
