[half-SOLVED] eth0 and eth1 getting swapped every time

andre.ramaciotti · 2009-09-10 13:35:35

Hi,

The title says it all, but I don't know what else to do.

I've tried putting the modules in order in the MODULES array in /etc/rc.conf, but it doesn't work. Apparently, the modules in MODULES aren't guaranteed to load in the order they are anymore.

I've tried following this wiki page, about Udev, but it didn't work, too.

I also tried closing my eyes and pretending it doesn't happen, but it didn't work too.

TIA

Try using aliases in /etc/modprobe.d/modprobe.conf, such as the following

alias eth0 your_module_name
alias wlan0 other_module_name

andre.ramaciotti · 2009-09-10 13:43:12

Wow, that was quick.

I thought in doing that, but after reading "man modprobe" I thought that "alias" wasn't meant for this kind of configuration. I'll test it and I'll report here.

Thanks.

Mr.Elendig, Are you sure you did read what I wrote?

Can you help me debug it instead of being a smartass?

brazzmonkey, I've tried using alias, but I can't get the wireless connection to work now.

/etc/modprobe.d/modprobe.conf

alias eth0 sky2
alias wlan0 wl

eth0 (wired) is up and running, but there's no sign of wlan0 or eth1.

iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

vboxnet0  no wireless extensions.

ifconfig eth1
eth1: error fetching interface information: Device not found

ifconfig wlan0  
wlan0: error fetching interface information: Device not found

hwd -s
and see what module does the wireless card use.
Recently sometimes at boot b43 autoloads before wl and takes control over the wireless card, which, alas is bcm4312 and the open source driver is incapable of controling. If this is the case hwd -s will report the module as b43-pci-bridge and you'll have to modprobe b43 & modprobe -r b43 and then reload the wl module.

brazzmonkey · 2009-09-10 14:23:10

Make sure you load the proper modules, add them to the module array of rc.conf and disable MOD_AUTOLOAD. Then reboot and see how it goes.

andre.ramaciotti · 2009-09-10 14:25:31

I didn't think that could be the problem ("b43" is blacklisted in the MODULES array and it isn't loaded right now, only "wl"), but you're right, hwd -s did show b43-pci-bridge as the module being used.

I did

rmmod wl
modprobe b43
rmmod b43
modprobe wl

but I still can't get any other interface to work (neither wlan0 or eth1).

This is my dmesg after the commands above:

You could always use rc.local, remove the modules for your network cards and reinsert them by the order you want.

Gen2ly · 2009-09-10 15:44:32

I've had to do like Mr.Elendig on my Debian system because I had two network cards of the same brand. Did you get the mac address right when you edited /etc/udev/rules.d/10-network.rules??

andre.ramaciotti · 2009-09-10 15:59:02

R00KIE, I'll try it, thanks.

Gen2ly, I did exactly as it's in the wiki.

stryder · 2009-09-11 06:07:26

I too use udev/rules.d to solve my problem, mapping the cards to lan0 and lan1. You seem to be continuing to use eth0 - the advice is to use something else.

I also had a problem where the tulip module kept taking the place of dmfe which is what one of my cards needed. What finally worked for me was to add my network card modules to /etc/mkinitcpio.conf so the right modules are loaded first, and rebuilt the initrd image. HTH.

andre.ramaciotti · 2009-09-11 12:50:40

stryder, I did exactly as it's in the wiki, with 'lan0' e 'wlan0', but thanks for your tip.

I'll try to set everything up in rc.local as R00KIE suggested.

hw-tph · 2009-09-11 14:10:24

Read the manpage for iftab: man 5 iftab
Quickest and cleanest way, IMHO.

Yeah, except it doesn't work here.

It's half working. I've edited /etc/iftab and I've put 'ifrename' in /etc/rc.local . My wired connection does get renamed, but my wireless doesn't. It gives me an error saying that eth1 is busy, which doesn't make sense as I load wicd only after ifrename.

I think now I have a predictable behaviour: wired is always 'wired' and wireless is always 'eth1', so I'll keep it. It wasn't exactly what I wanted, but it's better than completely random.

As hw-tph's solution is the one that suckless™, I'll stay with it. Thanks to all of you that tried to help.

andre, how about instead of snapping at me, you post your udev rule, including where you put it, and the mac adresses for your cards?

Edit: hmm, didn't see that wiki page link in your op before it was edited >_>

Mr.Elendig, I don't want to have problems here in the Arch forums. I know I overreacted to the provocative tone in "The wiki 1 - you 0", but it's nothing personal and I'm sorry.

cat /etc/udev/rules.d/10-network.rules 
SUBSYSTEM=="net", ATTRS{address}=="00:23:ae:ea:ca:c6", NAME="lan0"
SUBSYSTEM=="net", ATTRS{address}=="00:23:4e:85:c4:b2", NAME="wlan0"

and the MAC addresses are the ones above, but just to be sure:

udevadm info -a -p /sys/class/net/wired | grep address
    ATTR{address}=="00:23:ae:ea:ca:c6"
udevadm info -a -p /sys/class/net/eth1 | grep address 
    ATTR{address}=="00:23:4e:85:c4:b2"

My cards are:

09:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040 PCI-E Fast Ethernet Controller (rev 12)
0b:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

And the modules they use are sky2 (open source) and broadcom-wl (closed source).

hw-tph · 2009-09-12 08:35:48

Andre, I haven't really used iftab renaming for wireless interfaces much (only with plain WEP, no fancy stuff like wicd or NetworkManager), so I probably should have put a disclaimer in my post. At least, it is some means of getting it sort of working.

andre.ramaciotti · 2009-09-12 12:27:55

Thanks anyway, at least now I have a predictable behavior. Maybe it's the driver fault, as it's proprietary and Broadcom's drivers aren't famous for their high quality. Maybe when b43 finally supports my card things will get better.
