I spent 12 hours trying to discover why I could get either computer to see
each other, let alone the network.
I wasn't even getting data in tcpdump. On one machine, the link light
would disappear immediately after the boot was finished. The other would
remain on. Both machines are Athlon 1,000MHz 512 MB ram, with the 3com
#C905C NIC installed. Kudzu showed them as correctly identified. Finally,
after ruling everything from the hub, cables, configuration etc., out, I
replaced the 3C905C's with 3C905B's, and immediately everything worked.
I would like to suggest that kernel 2.2.17-14 does not properly support
the 3COM 3C905C network Interface Card. Both cards work perfectly in a
Steps to Reproduce:
1. Install RH6.2 With ALL Updated RPM's including kernel 2.2.17-14 on two
2. Configure the machines on a network and run tcpdump on one machine and
ping the machine from the other one while running tcpdump in another
virtual teminal. DO this from each machine.
3. You'll see that the traffic never get's to the other machines. Kudzue
correctly ID's the card on uninstall as a 3C905C. Replace the NIC'
s with 3C905B's and all works as it should. The 3C905C is a new version of
Actual Results: I saw no packets being received or successuflly making
it's way to the other machine. I could not ping any place including
www.yahoo.com. I could do localhost pinging and see traffic to localhost
Expected Results: I shopuld have been able to perform common network
tasks with the 3C905C installed.
