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

thanks. that was even easier than i thought. matlab uses the mac address for verification, so when i motherboard with builtin ethernet blew up, i was locked out. now i'm no longer locked out, and can figure out the proper way when i have the time. :)
this does not always work, for instance with a wireless card using ndiswrapper
you need to change your .conf file withing your driver's folder located in
/etc/ndiswrapper/
which reportedly works, you simply change the line mac_address|XX:XX:XX:XX:XX:XX
to mac_address|
I do not currently have that working on gentoo linux at the moment however
it's worked for a couple people out there and it -is- the method listed for the wiki.
simply bringing the wlan0 down and ifconfig wlan0 hw ether
does not work with my gentoo build using ndiswrapper it seems to be overwritten w/ the
real mac address repeatedly.
To make permanent in openSUSE, edit /etc/sysconfig/network/ifcfg-*, add the line "LLADDR=00:11:22:33:44:55." Save/reboot
