Can't detect eth0

Hello. I recently did a stage 3 install of Gentoo kernel 2.6.11-r3. I know that there are other threads with the same problem but I couldn't solve my problem from there. Booting in the livecd my network works and I can access the internet.

After I boot into the normal environment, init does not detect my eth0, I installed dhcpcd and it says eth0 is not found. If I try to run /etc/init.d/net.eth0 start returns eth0 not found.

When I run ifconfig it only returns my loopback address.

So I followed advice of other threads and booted back into the livecd to see what modules were loaded. I have an On-Board Intel Gigabit Ethernet Controller. When I run lspci in the livecd, I see it loaded as a module.

When I boot into the normal gentoo environment and run lspci, I also see the Ethernet Intel Gigabit Controller module listed. However, any network command I attempt to run states that eth0 cannot be detected.

Any ideas?

You have to use rc-update to add it to your start up script, i.e.
rc-update add net.eth0 default. If this does not work, then try net-setup eth0. Also, if you compiled the driver as a module in the kernel, then you would have to add it to /etc/modules.autoload. I have it compiled into the kernel, but if it was a module, I would have to add 3c59x for my ethernet card. Don't know if coldplug would find it if you have support in the kernel, but I assume you have coldplug installed. HTH.

When I was installing Gentoo, I could not emerge hotplug or coldplug. It wouldn't connect to the server. Is this my problem?

Did you do either of the following?

This is out of my domain, but try a modprobe of your ethernet module. It sounds like it may be a kernel problem if you had an internet connection for the install but not after booting. See if you have the proper modules configured in the kernel. I would suggest that you compile it into the kernel and not install as a module. Are you using genkernel or configuring by hand? BTW, on my system /etc/init.d/net.eth0 is a symlink to net.lo. See if you have it on your system.

Ok I got it working. My problem was that I couldn't emerge coldplug during installation and that is why it was not loading the module at boot. I had to boot with my livecd and copy the resolv.conf to the new environment to download coldplug. Thanks everyone for the help.
