internal ethernet device not found

paranoid times · 10-11-2005, 03:50 PM

I just installed gentoo, and I'm trying to get the ethernet device on my motherboard running. I has run fine before, but i'm not sure how to load up a module for it to run manually (at least I think that is the problem)

the lspci -v info is:

Code:

0000:00:03.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 90)
        Subsystem: Elitegroup Computer Systems K7S5A motherboard
        Flags: bus master, medium devsel, latency 64, IRQ 11
        I/O ports at d400 [size=256]
        Memory at cfffd000 (32-bit, non-prefetchable) [size=4K]
        Expansion ROM at cffc0000 [disabled] [size=128K]
        Capabilities: <available only to root>

I put

Code:

config_eth1=( "192.168.1.2 netmask 255.255.255.0" )
routes_eth1=( "default gw 192.168.1.2" )

in my /etc/conf.d/net file.

eth0 is working, and connected to the internet, via dhcp. when I try starting eth1 I get this:

Code:

#  /etc/runlevels/default/net.eth1 start
 * Starting eth1
 *   Bringing up eth1
 *     192.168.1.2
 *     eth1 does not exist                                                [ !! ]

thank you for any help

How many NIC's you have there? Counting starts with eth0 ...

paranoid times · 10-11-2005, 05:26 PM

there is eth0 which is used for connecting to the Internet.
and there is eth1 which is used for connecting to the local network.

Sorry, didn't read carefully enough. You can load the module with 'modprobe' (man modprobe will guide you), hopefully you included support for your NIC's chipset when building kernel. And there is a chapter in Gentoo handbook describing how to load it at boot time.

alright. I'm not sure where the right module would be. is there a list somewhere? or how do I find out what module to load (the man page didn't help me in that front).I could be missing the module, and need to recompile the kernel, which is fine. but I need to know how to find out which module to have it load. right now I'm lost in finding out where the module would be.

Perhaps easyest is to do 'make menuconfig' for kernel and browse thru possible NIC's.

I tried that, but I'm not sure which module I need for my device. I looked about, and everything that looked fimular was already selected. that doesn't mean that much as I had never compiled a kernel before yesterdey. but I'm still unsure of how to identify which module(s) I need to have loaded to get my network device to work.

The module should be /lib/modules/YOUR_KERNEL_VERSION/kernel/drivers/net/sis900.ko

paranoid times · 10-11-2005, 08:48 PM

ahh, awesome.
two things:
1: how did you determine that?
and 2: I don't have it (where should I get it from, a kernel recompile? or the internet?)

thanks

First, I fired up that menuconfig and saw your chip mentioned under sis900, there is help for almost everything in kernel config, reading the help I determined the module is called sis900.ko
I've always known where Linux keeps the modules, don't ask how I found it out first time. I don't remember. Oh, maybe there was a time when kernel install included manual copying of those modules to the mentioned location.
Second, yes, you have to compile modules with kernel.
Good luck.
