NOTE: In this example we will change the MAC address for the eth0 interface

  1. Open your Command Line Interface

  2. Now we are going to shutdown the eth0 Interface using the command below

    ifconfig eth0 down
    
  3. Now we change the Hardware Address for the eth0 interface

    ifconfig eth0 hw ether 00:1d:72:dd:00:6f
    
  4. Now we activate the eth0 interface again

    ifconfig eth0 up
