Network failed at boot[solved]

starting eth 0
dhcp
network interface eth0 does not exist
please verify hardware or kernel module cdriver
ERROR:cannot start netmount as net.eth0 could not start.

I recompiled the kernel to make sure that is had everything checked that was supposed to have checked: it did(by the handbook anyway). And I configured everything needed by the handbook exactly!

this is my ifconfig when chrooted into gentoo from knoppix:

Warning: cannot open /proc/net/dev (No such file or directory). Limited output.
Warning: cannot open /proc/net/dev (No such file or directory). Limited output.
eth0 Link encap:Ethernet HWaddr 00:11:2F:61:8E:9D
inet addr:192.168.0.131 Bcast:192.168.0.255 Mask:255.255.255.0

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1

this is my hostname:

# /etc/conf.d/hostname

# Set to the hostname of this machine
HOSTNAME="localhost"

this is my /etc/conf.d/net:

# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"

finally my host:

# /etc/hosts: Local Host Database
#
# This file describes a number of aliases-to-address mappings for the for
# local hosts that share this file.
#
# In the presence of the domain name service or NIS, this file may not be
# consulted at all; see /etc/host.conf for the resolution order.
#

# Imaginary network.

#10.0.0.3 myfriend

If you built the driver as a module, you'll want to autoload it at boot by adding it to /etc/modules.autoload.d/kernel-2.6. The knoppix bit doesn't help, since it'll be using it's own kernel and drivers.

It's a chroot into gentoo from knoppix. Therefore, you're running a knoppix kernel and knoppix drivers. ifconfig is just a program that checks the interfaces. It's irrelevant that it's the "Gentoo" ifconfig.
If you don't remember how you built the driver, then check /usr/src/linux/.config

Wanted to add that I've recompiled the kernel 6-7 times and their is nothing wrong with the way I'm doing it. All of it is loaded in the kernel no modules. The only thing I can think of is I need another setting when I make the kernel that is not in handbook. If anyone knows how I can go about finding out which ones I need to get my internet up, please help. Thanx!

I have a Via chipset with an on board via Rhine II fast ethernet adapter

What kernel version is this? I'm using 2.6.21-gentoo-r4, and in menuconfig, they're right after "VIA Rhine support".

You give very little information about what you have done. As the handbook does not know what network interface you use, we'll first check that you have the right driver. I assume you are not using genkernel.

Do the following

Still doesn't work I compiled them into the kernel not as mods!

I suppose you did remember to copy the new kernel to /boot and, if you have a seperate partition for /boot, that you did remember to mount it first.

Now, boot the machine and post the output of dmesg. You can save it in a file with the command

I don't know either. But if you boot your knoppix CD, you should have all sorts of graphical programs. By the way: You shouldn't use "localhost" as hostname, that might make some confusion, choose whatever else.

Have to leave now, i'll check later.

Ok, here's a trick:

When you are compiling your kernel i suppose you do

ok doing it now wanted to make sure this isn't a problem after I make the kernel

Yes, the new kernel isn't installed. Try
