Problem with my eth0 interface

Hello all,
I have installed Archlinux on my laptop via FTP but I've a problem.
During the installation my network works perfectly, but when I reboot for configuring my pacman.conf and for synchronizing the mirrors the network is death.
When I type "ifconfig" I have no eth0 interface....that's strange
Thanks for your help,
Iznogoud

Re: Problem with my eth0 interface

You need to give us some more information, like the model of your ethernet adapter (give us the output of '/usr/sbin/lspci |grep Ethernet') and how you connect (dhcp?)

You can try to do 'dhcpcd eth0' and see if this connect.

Re: Problem with my eth0 interface

Sounds like a kernel module problem, give us some more info, dmesg, lspci, etc.

Re: Problem with my eth0 interface

Thanks for helping me

First, I'm using dhcp for my network and when I type "dhcpcd eth0" the prompt return :

err, eth0: ioctl SIOCSIFFLAGS: No such file directory
Erreur de segmentation

Some other informations :

/usr/sbin/lspci |grep Ethernet : 

06:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)

dmesg |grep Ethernet :

r8169 Gigabit Ethernet driver 2.2LK loaded

ifconfig eth0 up :

SIOCSIFFLAGS: No such file or directory

All what I get are errors....or almost

EDIT : Here is my rc.conf:

#
# -----------------------------------------------------------------------
# NETWORKING
# -----------------------------------------------------------------------
#
HOSTNAME="fepc"
#
eth0="dhcp"
INTERFACES=(eth0)
#
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

my hosts.conf :

#
# /etc/hosts: static lookup table for host names
#
#< ip-address >   < hostname.domain.org >   < hostname >
 
127.0.0.1               localhost.localdomain   fepc

and my resolv.conf :

#
# /etc/resolv.conf
#
#search < yourdomain.tld >
#nameserver < ip >
nameserver 192.168.2.1

Re: Problem with my eth0 interface

A little bit news : when I use the Archlinux's fallback image I can use my ethernet connection. But not in the Archlinux's default image.

In the line eth0=dhcp there should be quotes around dhcp such as

eth0="dhcp"

Hope That Helps

Re: Problem with my eth0 interface

yes I'va made a mistake when I copied the rc.conf. I already have quote around dhcp.
Sorry for the mistake.

Re: Problem with my eth0 interface

Well if it works with the fallback image, the quick and easy way would be to set your /etc/mkinitcpio.conf to the same settings as in the /etc/mkinitcpio.d/kernel26-fallback.conf and redo your kernel26.img.  I'd guess that for some reason you need the ide hook for your network interface .  Just a guess?

But first make a 'diff /etc/mkinitcpio.conf  /etc/mkinitcpio.d/kernel26-fallback.conf' to know what caused the problem (solving is noting if you don' learn anything)

Re: Problem with my eth0 interface

Ok, the problem is when I put the "autodetect" in the Hooks of my mkinitcpio. So I rebuilded the kernel26 without "autodetect" and it works now
but if I want to use this hook I have to specify the module of my ethrnet card...but how can I do it ?
