This is all new to me btw, I know how to do it but have never bothered
to play with it :)

I just tried it on a client here using what i did in my last email on
eth0.

ip link set eth0 address aa:aa:aa:aa:aa:aa

The arp table on one of the servers I probed recorded this:

10.2.0.22     ether    AA:AA:AA:AA:AA:AA  C     eth0

Looks sufficiently spoofed to me.  Is the arp table showing what I want
to see so I feel happy it worked and is storing the real one elsewhere,
or is the server truly being dealt the fake MAC address from my client?
