Re: Identical MAC addresses, 2 different systems

You can assign a new mac address, with the following precaution:  bit 46
must be 1 (this means: Locally administered) Burned in addresses come with
bit 46 set to 0.
(bit 46 is the second bit of the OUI section).
I don't know if  your system supports any way to modify mac addresses, but
this subject has been
discussed previously on this list, so a google search should give some
positive results (there is a C
program floating around that is reported to work on many cards).
