I am running PCLOS on a p4 1.6 gh ibm it shows that my eth) is there but I can get no connectivity through it. the lights indicate activity on the NC but nothing.
any ideas?
On IfCONFIG, since it's on a diferent machine, shows that eth0 and lo are both up and apparantly operational. nothing indicates a problem. I have added another NIC and it also shows up in ifconfig also as up as eth1 and apparantly ok.
When I plug in the cable to the NIC, all lights flash both rx and tx as though data is moving but in PCLOS network mananger it shows no connection made. I have not set up iptables and none are set up by default that I know of.
on at least 6 other machines I have installed from the same livdcd , all but this has worked perfectly out of the box ( so to speak)
the machine is a IBM Netvista, 256 mb ram, p4 1.6 ghz processor, 40 gb hd, 3com ethernet.

I wanted to see the output of ifconfig to see if you had an IP address. Have you got a valid IP address for yor network? Have you set up a default gateway? Does your DHCP server pass you DNS server IP addresses?
I don't have a network. all I have is a cable modem to the internet. it is a seperate standalone machine.
I have no way to connect it right now to make up even a p2p because I lack even the wire or a switch, as to connectivity to the cable modem, I am not sure but it works on my main pc right off, just plug the line into the eth port and boom, operational off the bat. the other pc, no so much.
it is set up for dhcp as the main pc is.
If I understand you, you have two PC's one works, and one does not. You have a cable modem/router, and yes you do have a network, one PC at a time.
The router part is what dishes out the ip addresses through a DHCP server.
Do you know how to access the router? Have you got documentation for it? Many of the new ones supply the doc on a CD in a file.
We need to determine if you get a valid IP address when the failing machine is plugged in. Plug in the failing machine, open a Konsole, and run /sbin/ifconfg and post the results. Without that we are going nowhere.
I seem to show that it is able to see activity on the new NIC, but it still doesn't seem to want to "use" the NIC or access it somehow.
Do you have two nic's in this machine? Does eth0 work? Have you tried it?
What you posted form ifconfig shows eth1, and it does not have an ip address. It will not work without an ip address.
I would also recommend you get away from configuring the nic's with the wizards. I have seen way too many problems using the wizards. I helped another member resolve a wizard created 'won't communicate' type problem, and the fix, if you like was to re-do the configuration on the wizard. That got his going, but we don't know why.
I much prefer to edit the files directly, then I know what is there. With the wizards you are just hoping they are not buggy and work. You can't see what is really there.
It might be worth checking at this point what hardware you have, and what drivers are loaded. If you open a console, as root run the command 'lspci' This will list all hardware on the pci bus linux can see. Post the line(s) for your nic(s). Also run lsmod, and post the lines for the driver(s) that are loaded. The name of the driver is usually related to the nic. You could also have a look at harddrake. It may shoe the information. Just want to make sure you have the correst drivers loaded for the nic(s).
I can see you have two nic's and you have drivers loaded for both. Note the tulip driver is not doing anything. If you look at the eepro100, it is listed as using mii. Tuplip is not.
I suspect this is the root of the problem. It would be good if you could disable eth0 in bios. You have to enter the bios setup program before the system boots up. IBM thinkpads are usually the F1 key just after power up. If that doesn't work, post the exact model. We can look it up on IBM's support site. They have very good documentation. We could always use rmmod to remove the driver for the Intel ethernet controller.
