Ah ha! I thought I was the only one having problems with the de driver. Performance just went right down the tubes running 100BaseT at Full-Duplex. However, after days of troubleshooting why I was getting 6Kb a second across a X-over cable between two machines, I ran it down to the Full-duplex operation. Apparently, When half-duplex was enabled, performance was great...at full-duplex...6kb a sec (even ftp stalls). FreeBSD 3.3-RELEASE and 3.3-STABLE...same results on both. Anyone else? ******************************************************** Nick Rogness Speak softly and carry Systems Administrator a Gigabit switch.
