I'll be incredibly impressed if you can do that. I'm under the impression that it is sort of like your machine's serial number, part of the hardware.<br><br>It seems like you sometimes hear about hackers, virus makers and kiddie porn aficionados getting caught because they've finally tracked something down to a particular machine via the number on its ethernet card. You can jump IPs and ISPs easily, but there is only one number per ethernet card. At least I think... next time I drop by JC will have changed his. <br><br>Yeah, I guess I could get a router and bypass the IT folks when a new machine comes in, but its the universities' machines not mine. I should probably just do it their (slow) way. <br><br>
