Hello!

Im running debian kernel 2.6

I have direct ethernet connection to internet on one interface (eth0) and a local network on another (eth1). Everything was running fine until yesterday, when I shut down the system and then when I booted today I had no connectivity towards the internal network on eth1.

Both cards use the same driver and were working just fine.

ifconfig returns:

eth0 Link encap:Ethernet HWaddr 00:30:05:2A:1B:A0

ifup eth1 tells:

SIOCADDRT: Network is unreachable
Failed to bring up eth1.

and route -n:

Now I understand that the gateway cannot be reached for some reason.
I suspect some file is corrupt but I don't have any idea how to correct this.
I also assume this has nothing to do with iptables since I cannot get the interface up.
What upsets me is that I can ping 10.0.0.254, can I assume this means that the network card is functional?

What i want to determine if this is a sofware problem or if my network card is broken.

I have opened the machine, cleaned it and reseated the network card which is on a PCI slot. All this to no avail.

I appreciate any help you can provide, because right now I am quite confused!

did you try to put the network card to other PC and tested it? or how about changing the card to other PCI slot?
