After looking for a cause in the usual suspects (disks, power supplies etc) I finally managed to track it down to an unusual suspect. The freebsd box had a 3com 3c905. This was fine. It was connected to a windows box that had an intel 82559 based card. This also was fine, when it was connected to a switch. Because the switch has other duties right now, my network has had to put up with a hub for a little while. Connecting a 3c905 to an 82559 via a hub or crossover cable does not work. Furthermore, it does not work for a very well defined reason - 'netstat -I xl1 -w 1' doesn't show any network traffic at all. What it does do is eat truckloads of processor power on the FreeBSD machine. I do vaguely remember a post a long time ago on -hackers about 82559's not liking crossover cables, and it seemed just too weird to be true. Does anyone have the first idea exactly why this doesn't work? Thanks, Dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
