Unhappy network interface eth0 does not exist


Hi all,

Working on my first Gentoo install, and everything through the install process seemed to work smoothly.

But on reboot (first boot from HDD), I get the following error:

Starting eth0
Bringing up eth0
dhcp
network interface eth0 does not exist
Please verify hardware or kernel module (driver)

ifconfig only displays info for lo, no eth0.

This is my 3rd crack at installing this, running into the same error every time. Any help would be much appreciated.

Thanks.

I am not familiar with gentoo, however check lspci output(if command exist), check dmesg log, modprobe.conf check whether the eth0 module loaded or not and check lsmod output.
(the above mentioned things are based on redhat linux)

Hello jrodia,

please let us know which networkcard you're using. I think that you've build the kernel without support for this nic. Is the other hardware detected properly?

Did you:
rc-update add net.eth0 ? [or something similar]

I assume your net was working, since you said your installation [which requires internet] process completed successfully but on reboot you are getting this error?

Markush - it's an integrated NIC on a ECS KN1SLI nForce 4 motherboard. The other hardware does seem to be detected properly, including my nVidia GPU.

sHyLoCk - I get the following:

localhost-localdomain init.d # rc-update add net.eth0 default
* net.eth0 already installed in runlevel 'default'; skipping

Hello,

in the kernel-configuration there is in
Code:
device-drivers->Network-Device-Support->Ethernet(10 or 100Mbit)
an "nForce Ethernet Support". The module's name is "forcedeth". I'll recommend to use this and test if it works for your card.

That seemed to do the trick!

Now, what do I have to do to recompile the kernel so I don't have to "modprobe forcedeth" every time I boot the computer?

Many thanks again!

Hi jrodia,

you can compile it into the kernel instead as a module. But when compiling it as a module you'll create an entry in the /etc/modules.autoload.d directory (read the Gentoo-Handbook, the kernel section).
