eth0 device not found

Hello,
i have a problem with running network on my notebook. If i try "ifconfig eth0", gentoo says:

"eth0: error fetching interface information: Device not found"

I load pcmcia and 3c574 for my network card.

Does anyone have an idea what the problem could be?

If you are using a PCMCIA nic have you started the pcmcia service? Once started eject and plug the card back in, make sure it registers in dmesg, and that it registers as the device you think it is. Also from memory the 3Com cards needed the mii module.

Make sure the kernel driver for that nic is loaded. If you built it as a module check with lsmod. If it's not in the output try loading it with modprobe.

Is that after the installation, or it just stopped working?

I can suggest that your go through this checklist. Then post the output from the commands mentioned in the last part of the first post over there.

If i plugin and out the nic nothing happens no message appears. I loaded the modules manual.
lsmod shows me:

Module.........Size................Used by
3c574_cs......12424............. 0
pcmcia..........34216..............1 3c574_cs
pcmcia_core...38164..............2 3c574_cs,pcmcia

It never works! The checklist gives me following:
dmesg | grep -i eth: nothing

ifconfig -a :
only lo device

gzcat /proc/config.gz|grep -i NET
i only write the ones are set:
Config_NET_PCMCIA=y
Config_Net=y
Config_INET=y
Config_Netfilter=y
Config_netfilter_xtables=y
Config_Netfilter_XT_Match_Limit=y
Config_Netfilter_XT_Match_MAC=y
Config_Netfilter_XT_Match_State=y
Config_Netdevices=y
Config_NEt_Ethernet=y
Config_Net_radio=y
Config_net_wireless=y
Config_net_PCMCIA=y

Have you built your kernel with PCMCIA support?

aks · n00b Joined: 15 Oct 2006 Posts: 26

Not in the Kernel, as a Modul in makemenuconfig following row:

<M>PCCARD (PCMCIA/CARDBUS) support

I think the problem is, that in the folder /dev is no eth0. Could this be the problem?

Building the module is only the start, you have to start pcmcia-utils. Does dmesg show the card being registered?
