Network devices on SuSE 9.1

Hi,

I have SuSE 9.1 which was working pretty well, so far. Jesterday I changed
my ppp0 interface from manual to start onboot. Unfortuneatly, this mixed up
all my interfaces, meaning, that my wlan is now eth0 and my ethernet is now
eth1. This is annoying, because it makes me change my firewall settings and
so on. Changing the value back to start manual on the ppp0 does now not
make any changes.
SuSE made some changes with the config files in the new release, so the
config for eth0 is not stored in ifcfg-eth0 but in a file called
ifcfg-MacAddress. Now I don't know how to tell the interface on which
device to start. Has anyone already experienced this problem? Thanks in
advance, Alex.

I think that the kernel assigns the names based on the order it found
them. This behaviour can be steered a lot by the file /etc/modules.conf
my aliases are
alias eth0 8139too
alias eth1 ne2k-pci
basically linking the driver to the numbers. If you have 2 identical
cards you might need to specify which irq or io they use to separate the
both...

Yes, I had a look in modules.conf. This file is now empty! Instead, there is
a modules.conf.-
In this file, there is the line: alias eth0 driver for my 3com card. If i
type ifup eth0, my D-Link card goes up. Do you have any other ideas?
