Spoof MAC Address on Linux

Spoofing a MAC address on Linux is quite easy. It does require that you shut the interface down however. Shut the interface you want to spoof down, and then run ifconfig.

ifconfig eth0 down
ifconfig eth0 hw ether 00:11:22:33:44:55
ifconfig eth0 up

Instructions for openSuSE (to make the change permentant):

open root konsole and type: kwrite /etc/init.d/boot.local

then add 3 lines to the end of the file:

/sbin/ifconfig eth0 down
/sbin/ifconfig eth0 hw ether AA:50:8D:61:C4:AA
/sbin/ifconfig eth0 up

where you should replace AA:50:8D:61:C4:AA with your mac address and eth1 with eth that you get by executing /sbin/ifconfig

Now reboot
