New kernel + new udev. network cards detected backwards...

I just updated my kernel and udev etc and I am now finding that the wireless and wired nics are reversed.  My wired nic (bc44) is now eth1 and wirless (ipw2200) is now eth0.  Now before I go and reconfigure everything to use the new nic names (no pun intended) is there a quick way to change them back, ie a quick udev rule etc..

afaik you can use /etc/modprobe.conf to set the names,

alias eth0 bc44
alias eth1 ipw2100

give that a shot. the name reversal happens when the modules are simply loaded in a different order to what they have been previously. ie, ipw2200 is being loaded first.

I had the same problem with the archlinux-kernel. So I've switched back to my custom-made-kernel and now it's working as  I want it to work

Re: New kernel + new udev. network cards detected backwards...

load the modules in right order and you don't need a custom kernel.
MODULES=(!moduleA !moduleB moduleA moduleB)
and all should be as you need it

Re: New kernel + new udev. network cards detected backwards...

not really... here's the line from rc.conf

MODULES=(8139too ipw2200 ide-cd asus_acpi arc4 crc32c ieee80211 ieee80211_crypt ieee80211_crypt_wep speedstep-centrino cpufreq_powersave cpufreq_userspace freq_table cpufreq_ondemand)

eth0 should be 8139too, eth1 ipw2200 - and it didn't work....

not even adding

alias eth0 8139too
alias eth1 ipw2200

to /etc/modprobe.conf did work.

This configuration worked fine with the previous kernel (I guess kernel26-2.6.15.3-2.pkg.tar.gz)

Take a look at udev rules. It's the most elegant solution. I belive there is a part in the wiki about them.

Re: New kernel + new udev. network cards detected backwards...

sorry to say but you didn't use my advice i said !moduleA !moduleB and then moduleA moduleB then it works!

Re: New kernel + new udev. network cards detected backwards...

why do I have to disable the two modules first?

Re: New kernel + new udev. network cards detected backwards...

So they got loaded in order...

Re: New kernel + new udev. network cards detected backwards...

I think the udev way is probalby the most elligant solution.. I've been meaning to read up on that anyway to make rules for various usb sticks and cameras etc.. I'll give that a shot and let you all know what happens.

Re: New kernel + new udev. network cards detected backwards...

anyway, disabling and enabling the modules is not working either:

MODULES=(!88139too !ipw2200 8139too ipw2200 ide-cd asus_acpi arc4 crc32c
ieee80211 ieee80211_crypt ieee80211_crypt_wep cpufreq_powersave
cpufreq_userspace freq_table cpufreq_ondemand snd_intel8x0)

it's now creating an eth2? ;-)

Try this, it's simpler and "more correct" for udev:
