eth1 and eth0 switch [SOLVED]

fini_fly · 2009-12-04 15:30:03

When my computer boots up, eth1 and eth0 will randomly switch even after I followed these instructions: http://wiki.archlinux.org/index.php/Ude … _Each_Boot.

It seems to happen like 1 out of 10 times I boot up, so I'm not sure what's going on here. Any thoughts?

root@localhost$ mv /etc/udev/rules.d/75-persistent-net-generator.rules.optional /etc/udev/rules.d/75-persistent-net-generator.rules && echo "Success!"

Ihad the same problem, until I noticed that I had not only lowercase characters, as the wiki says clearly. Sure you followed the instructions to the letter?

Yes, all of the characters are lower case.

Did this, I'll have to report back later to see how this works. Thanks for the help.

If those interfaces are two network cards and you only need one, you may simply unplug the other.

Probably not, my old laptop's wireless card was named "eth1".

Well, I only created the udev network rules and everything worked fine.

tvale - fyi, eth1 is the second ethernet interface created by the kernel and the appropriate driver, eth0 being the first. The device name does not refer to a specific item of hardware, but to the order in which the interfaces are created.

@ tvale
Your laptop probably had a wired network interface too - it could be named eth0.

tvale · 2009-12-04 20:57:15

Yeah, I see.
I (wrongly) assumed that you meant he had two wired network cards. I was just saying that the device being called "eth1" didn't mean it was a wired card.

By the way, not wanting to start an off-topic, why did my old laptop had the wireless card named "ethX" and this one has "wlanX"?

karol · 2009-12-04 21:04:28

I did suggest that if he doesn't use the other card he can simply remove it. If it's a laptop it probably won't fly, but if it's a desktop - why not? :-)

tomk · 2009-12-04 21:24:27

tvale - the driver determines the name. Current wireless drivers use the kernel's mac80211 subsystem, which creates wlanX devices. Legacy drivers often used ethX.

Ah, I see. Thank you.

This seemed to do the trick as there hasn't been a switch, so I'll mark this thread as solved! Thanks!
