Slightly off topic, but has anyone ever seen 2 separate systems with the same MAC address? I thought this was a "never supposed to happen" kind of thing as MAC's are supposed to be globally unique. However, I've had this happen twice now with clients on my ADSL network (I use an OpenBSD/PF box as a router/dhcp server).
In the first case, it was an onboard AOpen NIC on the motherboard, this time it seems to be an SIS nic. (Judging by the vendor prefix). NICs are usually in Windoze systems, so I'm not sure if I can use software to set the MAC. And if I could, is there a 'private' range for MACs that could be used if I did set it to something else? That way I don't accidentally give them another mac that might be duplicated. Thanks. Sincerely, Kirk Ismay System Administrator The Net Idea
