eth0 not found

rnarch · 2012-04-23 17:28:10

I have installed Arch from the install livecd on a new partition and it is booting all right but dhcpcd command does not find eth0 interface. The entry is there in rc.conf .

interface=eth0
address=
netmask=
gateway=

'network' is there in the DAEMON. During the installation I followed the Beginner's guide in the wiki. I am not sure what else needs to be checked.

Could you post output of 'ip link show' and 'lspci'?

rnarch · 2012-04-23 18:31:26

'ip link show' shows only lo; no eth0
'lspci' shows Realtek PCI express Gigabit ethernet controller.

EDIT: The advice in this post is stupid advice.

Hmm... do the e100 or e1000 kernel modules show up in lsmod?

I'm pretty sure those are Intel NIC modules.

You are using wrong driver or no driver at all. Post output of 'lsmod | grep ^r8'.

Without quote and dot at the end of course.

$ lsmod | grep e100
$ lsmod | grep ^r8
$

There is no output on any of the commands. It is not working even with 'fallback' option of the grub menu.

On a working arch system from a separate partition, the output is:

$ lsmod | grep e100
$ lsmod | grep ^r8
r8169 41768 0
$

Try modprobing the r8169 module.

seveg · 2012-04-24 07:40:16

Like alphaniner said, e100 is Intel driver, you need to load r8169.

rnarch · 2012-04-24 10:50:52

The command 'modprobe r8169' does not work. Module is not found.

seveg · 2012-04-24 11:18:50

What about r8168? If you dont have any realtek driver, you can download it here.

maybe your network card is too new. download up-to-date kernel from some mirror, copy it to the machine and install it using "pacman -U linux-somenumbers.tar.xz.pkg" and reboot. the module should be loaded automaticly...

this should show you all ifaces, so if eth0 is there, the card is working

I checked in Packages ( http://www.archlinux.org/packages/?sort … =&limit=50 ). There is no package starting with 'linux'. I am not sure what I need to download. I also checked for kernel in the wiki. There are details for kernel compilation with ABS but not downloading a kernel package which I can install with pacman.

Can I copy vmlinuz and initrd from a working Arch installation to this partition?
