Attempting to DHCP always fails with "Operation failure". I've configured the nic with static parameters (via netcardconfig) and ifconfig seems to report everything okay. However I can't ping anything other than the localhost. Curiously enough, I started ethereal while ping was running and the only packets it displayed were ARP requests (for the "pinged" IP). Running "arp" also just shows an empty table.

lsmod shows 8139too and mii loaded. I've tried mii-tool to reset, restart auto-negotiation and force specific medial all without success. I have noticed that lsmod reports the size of 8139too as 17128 under knoppix but as 16448 under RH7.3.

I'm greatly impressed with knoppix. The machine also has an ATI TV Wonder which" just worked" under knoppix (you wouldn't believe the battle to get it working under XP However I need to solve this networking trouble.

Any clues?
Thanks,
FYI... PROBLEM SOLVED!!!!
There was a clue in the system startup messages (dmesg):
"NETDEV WATCHDOG: eth0 transmit timed out"
Since the networking configuration seemed okay and the mii-tool command seemed to work (i.e., the light on the switch would flash when auto-negotitation occurred), the problem seemed related to how the nic hardware was handled, (especially with the transmit timeout error).

Simply booting with: "knoppix noapic" makes everything work.
From other sources on the net this issue appears to be systemic to debian and not directly related to knoppix.

Hope this info may help others who have similar troubles...
Cheers,
