[solved] My eth0 has disappeared > no network

eDio · 2009-12-13 11:07:28

Hello.
Today after boot there was no network on PC. I've tried to switch from kde network manager daemon to network daemon, but this didn't help me.

Then I noticed, that in rc.conf in MODULES array were lot of different modules and they were listed twice! Besides one from each pair was blacklisted!

Info
MB: ASUS P5k
Ethernet card: Atheros Attansic L1 (AFAIK module "atl1")
I am connected through router with IP 192.168.1.1. It's IP is used as gateway and DNS server.
IP of my eth0 is 192.168.1.2.

Here is my rc.conf after fixing an issue with MODULES (I don't know if I fix it correctly)

Network daemon fails to start because of

192.168.1.2: error fetching interface information: Device not found

And there is no /dev/eth0 or something similar.

I need help with fixing this.

TNX in advance.

edit:
Maybe, I need to add, that yesterday I've done a lot or pacman -Rsn. I have removed some gome and kde3 stuff, but maybe pacman removed as dependency some package, that is essential for networking...

Just tried ifconfig -a
It returned a lot of stuff for eth0 but also there was smthng like "There is no IPv6 router"...

I really have no idea, what have happened

I think your static IP should be configured something like this in /etc/rc.conf:

eth0="eth0 192.168.1.2 netmask 255.255.255.0 broadcast 192.168.1.255"
INTERFACES=(eth0)
gateway="default gw 192.168.1.1"
ROUTES=(gateway)

I used kde network manager too long, so even forgot how rc.conf should looks .

I have fixed my rc.conf as you suggest.

Also, as was suggested on some Debian-related forum, I removed avahi (with breaking all dependencies) to solve IPv6 issue.
Also, I have removed kde network manager.

Don't know, what caused this problem at the beginning (yesterday there were no any problems, and today networking suddenly disappeared), but now I use standard network daemon, I have reinstalled avahi and all works fine.

Thanks.

Off topic, but cool Arch logo.

Thanks. It was created from svg in GIMP under Arch
Now it looks a bit trivial to me, but I have no time to change it.
