How to Change our MAC Address on Ubuntu ?

Today I’ve received new Desktop computer for my office. It was nice until I realized I have to contact network admin. He was out already…  So simple solution was to do manual change of MAC address and use that one from previous desktop.  Here are steps

#sudo  vi /etc/network/interfaces

than when you are using dhcp a I do just change text in following manner:

auto eth0
iface eth0 inet dhcp
hwaddress ether 00:00:00:00:00:00

then close vi and run this command

#sudo /etc/init.d/networking restart

And you are connected back !
