Network Problems - Sunfire v100 - Ubuntu Server 7.10

[jpelegrin]

I'm having problems with packet loss for all network connectivity. Incoming pings are successful 80% of the time, outgoing from the server successful about 75% of the time. Here is some output data. Please notice the RX/TX packet errors/drops.

ifconfig

Bus error



Any help would be most appreciated. The server is plugged into a Linksys router, no wireless involved.

Thanks,
Jeremy

As a follow-up, the LED for the second NIC on the server was unplugged, but blinking rapidly. I plugged this NIC into a hub and activated it and while I am still receiving errors, the network communication is reliable. I will use both NICs and split the listeners between them.

Thanks,
Jeremy

could you run
ethtool -i eth0

Sorry for the delay. Networking is working, but I have to restart it every hour or so. Still lots of errors.
