Changing MAC address of your network cards on Linux

See the current MAC values

erogol@erogol-G50V ~ $ ifconfig -a | grep Ethernet
eth0      Link encap:Ethernet  HWaddr 00:22:15:3a:36:93
wlan0     Link encap:Ethernet  HWaddr 00:15:af:dd:94:91

Stop running of the card

<pre ">erogol@erogol-G50V ~ $sudo ifconfig eth0 down

Change the MAC address

erogol@erogol-G50V ~ $ sudo ifconfig hw ether 00:22:15:3a:36:83

Start the card running again

erogol@erogol-G50V ~ $ sudo ifconfig eth0 up

That's all. You might see the new MAC address for check.

Why I need to change the MAC address. Continue reading Changing MAC address of your network cards on Linux
