I messed with stuff, and now I can't reach the network...

Hi.

I've had a debian box under my table for years, and it has worked fine, since I haven't touched it.

Today I touched it, and it stopped working.

In short, I'm a total n00b when it comes to linux, I lack most of even the most basic knowledge on how it works, but still I thought "how hard can it be?", and thought I should try upgrading it and install a gui on it.

After some googling, I found out I could use "apt-get update" and "apt-get install x-window-system kde kdm" to get a much needed gui.

This failed with this and that dependency missing, so I kept on and tried (this is from the history buffer) these commands, but all had some dependency missing:

apt-get install kdegraphics
apt-get install kdvi
apt-get install libc6
apt-get install lsb-base
apt-get install glibc-2.7-1
apt-get install clamav-freshclam
apt-get -f install

I rebooted, and it didn't seem to come back up. Went and found a keyboard and a monitor, and found it had booted after all. Problem is I'm not able to connect to the network. I have a cisco switch, so I see the interface go up and down as I reboot or unplug the cable, but I can't see any mac-address on the port.

I can ping the loopback-interface and my own IP, but I can't ping anything else on the network. Arp -a comes up empty. Get ICMP destination unreachable message from my own IP when I try to ping anything.

Ifconfig shows eth1 with mac-address, correct ip/mask/gw, but shows 0 on all statistics (RX/TX packets etc).

Anyone got a clue what I might have done to cause this (cause I don't)? If you want me to find information, tell me how, cause I most likely don't know how.

Post the results of ifconfig. You can get them to a text file by going ifconfig >file.txt. You could also post contents of cat /etc/network/interfaces. Were you using putty to do the upgrade? Maybe you need to backup all your data and reinstall debian. It is not too hard to do.
