Just change the ordering in the persistent net rules way to what suits you best. Just make sure that every network card has a different ethN ;). -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

It's also why I am careful to fix the subject lines. Here's the answer to the problem: UDEV rules are never removed, only added. The fact that I have plugged USB wireless interfaces into this system has incremented the file 70-persistent-net.rules up to eth2 behind my back. I had a motherboard failure a month ago, and when I put in the new motherboard I was not surprised that the new ethernet port (since I kept the same system drive, no reinstall) was given a new ethernet number, eth3. The bug which Mr. Goodenough mentions above, for a short time, reverted my interface to eth0. Not knowing this was a bug, I figured the system had simply defaulted back to 0, that what I have learned are called persistent rules had removed themselves. Woopie, fine by me. But, when the bug was fixed and UDEV started working again, the same entry was still in 70-persistent-net.rules to make it eth3. Ok. I can live with it. I guess it's better than the good old days when one's ethernet ports, if there were more than one in the machine, would sometimes swap places. Ah, those were exciting times, with real incentive never to reboot! Running Debian Sid means never saying one is bored. Thank you to all who replied, it's been a "learning experience".

I'm guessing, as I don't understand UDEV at all. Could it be that the update sees the existing rules, sees that they don't match the current setup, assumes hardware has been changed, and assigns a new port number to be safe. -- Regards _ / ) "The blindingly obvious is / _)radnever immediately apparent" What will you do when the gas taps turn?

Your ethernet card is having some sort of personality problem :-P

Oh, clearly udev wants to test your patience.

You know how to prevent this, right?

Have been any updates for the kernel?

Does dmesg ("dmesg|grep -i eth") tell you something about what's going on?

Why did UDEV renumber my ethernet interface again?
Dear Debianistas, I'm aware of _what_ UDEV is doing, that is, renumbering my ethernet ports to prevent conflicts. Yeah. There's only one, but it's getting renumbered "eth3". Trouble is, it wasn't renumbered yesterday. Just today. And a week ago. About a week ago, UDEV decided to let eth0 remain eth0, which was nice, but I had to change /etc/network/interfaces because it had previously decided that eth0 should be eth3, and had been doing that since I installed it two years ago. Yes, I'm running Unstable, so it's the UDEV updates that are doing this. That makes sense. What doesn't make sense is _why_. There is only one ethernet interface in this machine. Why is UDEV renumbering them _at_all_? Curt- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
