In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification.

MAC Spoofing is a hacking technique of changing an assigned Media Access Control (MAC) address of a networked device to a different one. The changing of the assigned MAC address may allow the bypassing of access control lists on servers or routers, either hiding a computer on a network or allowing it to impersonate another computer.

Simply replace “eth0” with your adapter and “11:11:11:11:11:ab” with the MAC you want.

ifconfig eth0 down
ifconfig eth0 hw ether 11:11:11:11:11:ab
ifconfig eth0 up
