We got a new server at work and I installed harddrive from the old system. Ubuntu 8.04 boots up just fine. The only problem is:

$ifup eth0
device not found

Ethernet Controller Intel Pro(100/1000)

$dmesg | grep eth

Should I add some sort of default ethernet module using modprobe or is there another way?

$cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address xxx

This question came from our site for professional and enthusiast programmers.

Please copy-paste exact commands and errors. I'm pretty sure you didn't run lspic, and I don't recognize device not found as the sole output from ifup eth0. Also tell us what you have in /etc/network/interfaces. – Gilles Jun 2 '11 at 12:57
The installer really should be detecting the Intel card. They aren't exactly obscure. What is the the output of lsmod, please? And, yes /etc/network/interfaces, unless you are using that network manager thing, in which case, paste the config file for that. And please tell us if you are using network manager. – Faheem Mitha Jun 2 '11 at 15:12
yes we are using network manager: – teaforthecat Jun 2 '11 at 15:32
sorry I can't paste with no network connection – teaforthecat Jun 2 '11 at 15:36
I added lsmod output and interfaces file is there anything else I could post? – teaforthecat Jun 2 '11 at 15:45

Try modprobe e1000 or modprobe e1000e.

this solved the issue: http://ubuntuforums.org/showthread.php?p=3370406 (recompiling the module)

sorry it wasn't more clear that the hard drive was taken from another machine
