This system is going into the 100 megabit portion of a 10/100 "hub with switch" (amazingly weird intermediate hardware generation; it has a 10mb collision domain and a 100mb collision domain with a switch connecting them) which is connected to a real 10/100 switch which is finally connected to a Cisco 675 DSL router (most of the traffic on this system is external). -- David Dyer-Bennet / Welcome to the future! / dd-b at dd-b.net SF: http://www.dd-b.net/dd-b/ Minicon: http://www.mnstf.org/minicon/ Photos: http://dd-b.lighthunters.net/
