Networking problems!

Hi!

I've installed Gentoo a while ago, it worked for a few days, when after an update the networking wasn't working any more. I tried to repar it by following some of the threads in this forums. The problem was sth. with firewire over ethernet taking over the eth0... Anyhow, I didn't manage to get it working again and left it as it was for a few weeks, due to lack of time.

Today I decided to give it a try again. So, when I do /etc/init.d/net.eth0 start, the error is: Network interface eth0 does not exist, please verify hardware or kernel module (driver). Ok, I booted the LiveCD, and got the module that's used for my NIC: 8139too (its integrated on a Ati Xpress 200p motherboard). Booted back to Gentoo, modprobed it and.... well nothing happened, same error. Then I tried to recompile my kernel, and use this driver as built-in. Didn't help at all....

So, I am out of ideas, any help appreciated!

Could you post logs like dmesg when you modprobe 8139too?

Ok I recompiled the kernel back to use the drivers as modules.

At startup the modules 8139cp and 8139too were already loaded. So I unloaded and reloaded them with modprobe, just for the sake of getting some dmesg output. Here it is:

Ok lol, please post output of ifconfig and /var/log/messages. Use http://rafb.net/paste/

I would first recommend you to read the handbook entirely again. Even rebooting in the live cd and repeat every network step (don't forget to copy dns info). (I believe you need to create net.ethX files which are links/copies of net.eth0 for each card, it's ok to have more than one working I think). Why did the firewire stopped taking control of net.eth0?

I know it's easy to send you back to the handbook but the thing is, if you installed it recently and it's not working then there's like 90% likely you did something wrong. First things first, post ifconfig, you can confirm if the card is loaded by checking if it's there. Make sure it's the right driver by reading the help in the kernel menu (the livecd uses an older kernel, so it doesn't mean the module is correct)

apperantly some modules are "happy" to coexist with others...

post: "lsmod", "ifconfig -a",
what version of udevd do you use?

One thing I forgot to mention. If I chroot to gentoo from Ubuntu or from Gentoo Minimal CD, the networking works fine....
Ubuntu uses 8139cp and 8139too, also...

Here are the links to outputs of lsmod, dmesg, ifconfig, /etc/conf.d/net.....

/etc/conf.d/net - http://rafb.net/p/L6v5iA33.html
ifconfi - http://rafb.net/p/Xnt3sP16.html
lsmod - http://rafb.net/p/m7qIuV92.html
dmesg - http://rafb.net/p/o0Py0i24.html
/etc/init.d/net.eth0 start - http://rafb.net/p/HpwI0232.html
resolv.conf - http://rafb.net/p/A70uge66.html

I went through the handbook again. Didn't help at all. When you add net.eth0 to runlevel with rc-update it said that it is already in there.....

Argh!

Ifconfig -a did the trick.I actually had a working interface, but it was eth2. I started it with no configuration at all (so, dhcp) and it now works

Thanks for the help!
