The MAC adress on the SparcStations I own don't have the hardware address stored on the NIC itself. Kinda funny when you first notice it. Hey, that le0 and that hme0 have the same MAC address! :) Downside is when your NVRAM gets corruped though, all nics default to FF:FF:FF:FF:FF:FF. It's fixable, but having everything set to broadcast might give an unsuspecting sysadmin some headaches :) Cheers, Emiel -- In 1869 the waffle iron was invented for people who had wrinkled waffles.
