network interface eth0 does not exist

[kurtg]

I'm having a few odd problems after my system crashed during an 'emerge -uNDav'. Dell kindly replaced my motherboard and I fined up the emerge, but I'm getting this problem:

* Caching service dependencies ... [ ok ]
* Starting eth0
* Running preup function [ ok ]
* Bringing up eth0
* dhcp
* network interface eth0 does not exist
* Please verify hardware or kernel module (driver) [ !! ]

As well as this:

# /etc/init.d/net.eth1 start
* Starting eth1
* Running preup function [ ok ]
* Configuration not set for eth1 - assuming DHCP
* Bringing up eth1
* dhcp
* network interface eth1 does not exist
* Please verify hardware or kernel module (driver) [ !! ]

where net.eth1 is my wireless. Oddly, I can get net.eth1 to work on an older kernel and I'm using a Verizon card to access the net while at work, so that is my ppp connection here:

seeker ~ # ifconfig -a

lspci shows both of my cards:

0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
03:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)

which are both built into my kernel. I'm currently running:

# uname -a
Linux seeker 2.6.24-gentoo-r4 #1 SMP PREEMPT Mon Apr 14 01:10:43 EDT 2008 i686 Genuine Intel(R) CPU T2500 @ 2.00GHz GenuineIntel GNU/Linux

I searched on the forums and I find vague references to a similar problems.

where the problem went away with a kernel recompile. Any ideas?

Are you using udev? I had a weird problem a while back where udev kept renaming my NICs every now and then ... I had to keep going back into the /etc/udev/rules.d/70-persistent-net.rules and manually change them back.

I don't know if that is relevant for you, but I'd give it a check to see if there are a few "extra" interfaces in there.

Thank! That's definitely part of the problem. I've been able to get my ethernet working again. When I commented out the eth2 line, it then picked eth3, etc. I changed it back to eth0 and it worked. Strange business.

My wireless is still broken, but that is next on the list. (I'm also having troubles with cups & printing.)

I'm glad you got your internet working. As far as the other two issues -- it would be best to create a separate thread for each of them. You'll be more likely to find answers, and it will be easier for other people, who are having the same problem, to find it as well.

Good luck!
