[Discuss] System receiving incorrect IP address

[worley at alum.mit.edu (Dale R. Worley)]

People have said that Mac addresses cannot be spoofed, but I've
discovered that they can be on some NICs.  Indeed, the first time I
tried it, I was surprised that it worked and even more surprised that
when I power-cycled the card, it kept the new Mac address -- so I should
have written down the original Mac address before messing with it.
IIRC, the command I used was "ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx".
