[getting a little off topic here :) ] This is a bizarre and extreme case, however, I have personally run into a case where multiple systems on the same network had NICs with identical MACs on them that were *not* the result of MAC spoofing. At the time I worked for 3Com and the 3C509 card was basically the most popular NIC around. 3Com had several different versions of this card: one for a TP connector, one for AUI, one for BNC, and a "combo" card with all 3 connectors on it. Since *no one* would ever possibly have all 4 instances of this NIC, and definitely not on the same network, they decided they could re-use MACs and get 4 times as many NICs using only 25% of the address space they had. Seems like a good idea. Except for the fact that all 3Com facilities could buy all 4 versions of the card at cost or below :) Since then, I've never relied on any system to really have the MAC I think it's supposed to have :) - -- Seeya, Paul -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Exmh version 2.2 06/23/2000 (debian 2.2-1) iD8DBQE8zsIGuweSOVPxKO4RAgeAAJ49PaleXvEyRSA9+1jKmkAgiiRifgCdHcOM 0Nkog8Q5YBbgXNrdemBPeGg= =WM5R -----END PGP SIGNATURE----- ***************************************************************** To unsubscribe from this list, send mail to [EMAIL PROTECTED] with the text 'unsubscribe gnhlug' in the message body. *****************************************************************
