Hello! Last week I noticed some strange messages in my log files: fxp0 : device timeout After that the ping bacame unstable, and somtimes the server was unreachable. Our we replugged the server from 100 Mbit/s 3com switch to ordinary 10 Mbit/s hub. It helped. The server started to work fine, but a few days after that the problems appeard again. It seems the network card in our server unpedicably swithes from 100 to 10 Mbits and from half-duplex to full duplex. When we plugged the server to uplink port in our swith, everything is working fine again... Our Ethernet card - Intel Ether Express Pro 100/s Can it be a flud or some kind of DOS-atack or it just a hardware problem? I tried another network card (also Ehter Express 100), but it's getting even worse - the server does not work at all. What is the best way to solve such a problem finally? Many thanks in advance... ----------------------------------------------------- Vladimir I.
