WEIRD eth0 problem on Slackware 12...

arfon · 07-25-2008, 03:05 AM

I swapped motherboards in my machine and everything came up fine except I have lost networking (Slackware 12). It's not a hardware problem because I am posting this message using the machine running a Slax live disc.

1) lsmod shows that the module is loaded (via_rhine).

2) dmesg says: "eth0: VIA Rhine II at 0xe9...IRQ19"

3) when I run "ifconfig eth0" or "ifconfig eth0 up" I get: "ERROR while getting interface flags: No such device".

4) I checked inet1.conf and rc.inet1 and both look okay (plus they haven't been changed).

5) I tried adding "alias eth0 via_rhine" to modprobe.conf with no success.

6) Killing the module (modprobe -r) and manually reloading the module does not work either...

7) I tried using two known good Realtek cards and they behave the same way.

Any suggestions?

What about rc.modules? maybe there is something from you old mainboard.

Grabbing at straws ... check that /etc/udev/rules.d/70-persistent-net.rules
hasn't changed it to eth1 or something ... if Slack-12.0 has that business.

Quote:

Slackware's udev implementation will automatically create rules files for your
optical devices (/etc/udev/rules.d/75-optical-devices.rules) and network
interfaces (/etc/udev/rules.d/75-network-devices.rules) on first boot.
If you add/remove/replace any of this hardware, and/or you "clone" a system
to another hard drive for deployment, you will need to either remove these
two files (so that udev will regenerate them to reflect the new/changed
hardware) or edit them accordingly.

From CHANGES_AND_HINTS.TXT on the Slackware 12.0 CD.
The names of these files have changed in 12.1.

rc.modules is okay. Nothing weird there.

eth1,2,3 does not exist either so I don't think it's a udev problem....

I've decided to use this opportunity to upgrade to Slackware 12.1 so, fugit.

Thanks for the input.

upgrading to 12.1 is a good decision. i had a similar problem with ath0.
then i tried "ip" instead of ifconfig. syntax is a bit different, but worked.
