When booting the computer I get an error from dhclient (eth0: no such device) and if I try to manually configure it, it gives me the same. I tried with knoppix, eth0 isn't there either, but I can configure it manually. When I do so, I can ping the IP address I gave it but nothing else (I'm sure the cable is working, tested it with my laptop.
So do I read you correctly, that you can configure it and ping other hosts under knoppix? By "configure it manually" do you mean assign it a static address, netmask, and gateway, and bring ifup with ifconfig?
Usually when you can ping a host with its numeric ip address but not with its name, this indicates you do not have any dns servers listed in /etc/resolv.conf. This information is usually contained in the lease you receive when you bring your interface up via DHCP (/var/lib/dhcp/), and automatically written to this file. Because you are bringing up your interface without DHCP, this information is not being provided.
Any ideas on how to troubleshoot this? I'm running sarge and I've tried with 3 different kernels (2.6.3, 2.6.0 and 2.4) but no go.
It will help if you can determine what you did prior to it failing. Did you install a different kernel? Off the top of my head I do not know what kernel module (driver) is required for your card. However, if you boot into knoppix again and execute a 'lsmod', you should be able to determine which module knoppix is correctly detecting.
Ensure that the kernel you are using either compiles this module into the kernel, or if it is included as a module, ensure that it is listed in your /etc/modules file.
I've also swapped the NIC (I happen to have the same one lying around) but that doesn't help either. Also, the NIC is detected (not sure where to look on the cli, but in kinfocenter it's listed under the pci devices (it's a realtek))
kinfocenter is able to determine the type of card whether or not the correct kernel module is loaded, so this doesn't help you much. Your problem is most likely not hardware related.
