Hi FreeBSD 2.2-STABLE 486/33 3Com 3c509 vs. Accton NE2000 clone UTP interfaces amanda-2.3.0 Amanda server - SGI Challenge-S, amanda-2.3.0 (plus XFS patches) I use the amanda package to backup a mix of unix systems and have had problems with a FreeBSD 2.2.x system for quite some time. The client PC will lose connectivity until the network interface is down/up using ifconfig. This was using a 3Com (ep0) card on a 486/33 running 2.2-STABLE (cvsupd frequently). I could never find anything in the log files which gave direct evidence for a problem other than routed complaining, this was infrequent and (of course) would never occur when I sat on the console and checked (netstat -m always seems fine even when the interface is locked). I dug out an old ne2000 clone and switched over to ed0 and backups work fine now (well no problems yet but they are infrequent) but interestingly arpwatch logged the following where the MAC is the amanda tape server (SGI Challenge S).

I have never had any other problems with the 3Com card only with amanda and arpwatch has never logged these messages until I switched over. Yours Puzzled of Oxford Neil
