Gentoo Ethernet Problem

asp55 · 10-11-2004, 05:56 PM

So I've installed gentoo onto a server for a client, but when I boot it off the install I get the following error:

Code:

*Bringing eth0 up 
SIOCSIFADDR: No such device 
eth0: unknown interface: no such device 
SIOCSIFBRDADDR: No such device 
eth0: unkown interface: no such device 
SIOCSIFNETMASK: No such device 
*failed to bring eth0 up

Now, I ran lspci while booted off the livecd and got the following:

Code:

0000:00:00:0 Host bridge: Intel Corp. 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02)

0000:02:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

So I tried chrooting into /mnt/gentoo and modprobing 8139too (Which someone said was the apropriate driver for said controller) but got the following:

Code:

modprobe: Can't open dependencies file /lib/modules/2.4.26-gentoo-r6/modules.dep (No such file or directory)

Now since I'm using 2.4.26-gentoo-r9 (not r6) I made a symlink to the correct folder and called it 2.4.26-gentoo-r6. I tried to modprobe again and got:

Code:

modprobe: Can't locate module 8139too

When I ran locate 8139too I got

Code:

/usr/src/linux-2.4.26-gentoo-r9/include/config/8139too.h
/usr/src/linux-2.4.26-gentoo-r9/include/config/8139too
/usr/src/linux-2.4.26-gentoo-r9/include/config/8139too/pio.h
/usr/src/linux-2.4.26-gentoo-r9/include/config/8139too/tune

/usr/src/linux-2.4.26-gentoo-r9/drivers/net/8139too.c
/usr/src/linux-2.4.26-gentoo-r9/Documentation/networking/8139too.txt

This is really baffeling me as to why it can't find the device when booting.... HELP! Please....

(Also what's odd is when I try to run lspci when booted off the harddrive I get "bash: lspci: command not found" anyone know why that would be?)

Oh, other potentially important information:

The ethernet controller is an onboard ethernet on an Asus P4P800S.

The liveCD has absolutly know problem detecting and using eth0, but the moment I boot it off the install, I get nothing.

lspci comes as part of the pciutils package so you'll have to emerge that if you want to use it on the installed system.

You can't really boot from the livecd and then try to load a module using modprobe after chrooting - the modules matching the running kernel (i.e. the one you booted from the livecd) aren't located in the chrooted environment but on the CD! You will have to either load the module before chrooting or boot from the installed system and then load the module from your hard drive.

When you succeed in loading the module, simply run /etc/init.d/net.eth0 restart to try start up the network. If it works, just add the module name (8139too) to /etc/modules.autoload.d/kernel-version. Also make sure that the net.eth0 init script is added to the "default" runlevel so it will be started each time you boot (rc-update -s will show you if it is).

All this is outlined in the installation handbook, and it's a good reference even after you have installed the system.

Håkan, thanks for the quick response. However, I'm still having a problem when booted from the installed system.

When I try to modprobe 8139too, I still get the error message of "modprobe: Can't locate module 8139too"

If I do it in the liveCD before chrooting, I get no errors, but it doesn't affect my problem one way or the other.

EDIT: Ok, I just went through, and realized I'd had it compiled in the kernel. Re compiled it as a module and all works fine now.

Good to hear you got it sorted. Welcome to Gentoo country.
