Depends on what OS you're under... Under Linux (and I'd guess that *BSD works
somewhat similar), you can change the hardware address of some network device
ifconfig <device> down
ifconfig <device> hw <hw-type> <address>
ifconfig <device> up
So, for example, to change my MAC to some random number (which is invalid,
because it's a broadcast address):
ifconfig eth0 down
ifconfig eth0 hw ether fffefdfcfbfa
ifconfig eth0 up
Of course, you need to call all this as root.
From Python, that would be:
os.system("ifconfig %s down" % device)
os.system("ifconfig %s hw ether %s" % (device,mac))
os.system("ifconfig %s up" % device)
Under Windows (2000, XP, NT?) there's also the possibility to change the MAC
of a network device, but I don't know if you can access this OS functionality
from somewhere else than the dialog box which offers it (maybe you can change
it somewhere in the registry, don't know).
