RH 7.3 and 3com 3c905c - Transmit error / duplex mismatch / vortex
jonsed
Running RH 7.3 with 2 3com 3c905c cards, eth0 is the internal lan via 10/100
switch, eth1 is going to a set top box (cable modem) for the internet
connection. Getting this error a lot on eth1 (eth0 seems fine):

I dug around the net looking for answers but didnt come up with much, other
than maybe my NIC and whatever device it ends up talking to are not agreeing
on full duplex. But not much info on how severe this is and how to fix it.
The vortex.txt file referred to gives advice about how to force full-duplex
and other options, but it is all a little over my head (sorry!).
Like i say, thanks if anyone can help.

You can use mii-tool to verify the settings on you interface.

Get the mii-tools from
http://www.scyld.com
and then fix the eth1 card at the correct settings - which should be 10Mbit
halfduplex, as the cable modem service isn't serving anything else AFAIR.
