[TriLUG] spoofing mac addresses

[paul]

Hi all, 

I have 2 nics in a machine, one of which serves a backend private
address, and the other of which is on the front end with 13 addresses
aliased to it (ie: eth1:1, eth1:2, etc...). I think what I am finding is
that I can only spoof the mac address on one of the physical interfaces
(eth0 or eth1), and not individual mac addresses for each ip address (on
the aliases eth1:1..). Is that the case or does someone know of a way to
make this work?

thx,
