Ethernet card stopped working all of a sudden
Recently I put together a cheap machine using scrap parts I've accumulated over the years. When it was finished I decided to test out Frugalware 0.5. It's a nice distro!, but that's beside the issue. Anyway, today I turned it off to move it to a new location and when I got it back up and running, my ethernet card stopped working. It's a 3Com Broadcam that came with a Dell I bought many years ago. It was working perfectly just earlier today, and I didn't do any serious config changes since then (except alter my iptables which mysteriously didn't save even after iptables-save?).
So far, I've ruled out the CAT 5 cable and the router, and the card itself seems to working okay. The LEDs on the card are blinking. Peeking ifconfig eth0 reports that the card is sending and receiving packets, but it always times out on a dhcpcd. One suspicious item I noticed here is that RX overruns is at 1. I also tried setting the IP and mask explicitly, as well as adding a default routing rule to my gateway's IP. I also looked at dmesg and syslog but I didn't see anything suspicious, though I may be overlooking something. I also issued iptables -F and iptables -P INPUT ACCEPT.
Running out of ideas here. I think I might try running a Live CD just to see if another system config can pick up an IP. Any tips?
Thanks in advance!
