#787263 - breaks networking for allow-hotplug interfaces

Let's make this official. There is a bug report on the Debian BTS [1] and at our brothers at siduction [2]. I would recommend to fix it with the "ugly" method:
sudo editor /etc/rc.local
add following line before 'exit 0'
where wlan0 is your wireless device (can be eth1 or some other device name)
This is meant to be fixed soon, but if you don't want to upgrade to the newest udev/systemd version (no matter which init system you use), you can use this dirty fix. But probably even the upstream bugfix won't solve it :)

Thanks man, just discovered the problem on a testncrashnburn install of BORK!64. Network trouble is a real itch, will wait a little bit on my proper install before I duge it. :)

Ladies, you can of course revert to libudev1 and udev version 215-18, if it bothers you very much. This shouldn't be a biggie, we usually don't track systemd:

I tried the fix you mentioned but ceni still show no values under hardware interfaces.

If you have put "ifup wlan0" in the rc.local file, the wireless network should start during boot. But it will still not be visible in ceni. That is my experience at least.

I finally got ceni to work by uninstalling systemd/udev updates... Everything's working as usual.

Of course with wicd I have no problems. :) But that would mean bloat.

People, have you tried (re/installing) the ifupdown package? Seems I don't need dirty hacks anymore after installing ifupdown.

i just did a dist-upgrade and ifupdown is upgraded there. haven't tried whether it fixes anything yet, ceni still doesn't show anything after the upgrade but i didn't reboot yet (couldn't be fucked, just booted my pc, not gonna reboot it immediately again) so maybe that will do the trick. definitely lots of udev updates lately.

I just did a dist-upgrade myself on Bork and letting ifupdown upgrade doesn't help that I can see so far.
Manually trying to start the interface, either eth0 or wlan0 is a no go, and neither show up in ceni either. Guess I will have to look which systemd and udev files to not let upgrade.
Time for a reload and start from scratch. Glad it is a fast install.

Thanks JMT for the feedback. What a PITA this bug is, and damned how I hate udev.

^ Time to go with mdev? :)

^ If this happens, we have to move the base. udev is completely integrated in (most of?) the (Debian et al.) kernels :( You can try, for fun:
sudo apt-get autoremove udev
and see what it is going to remove.

^ Oh no, I know (I remember trying mdev following Pidsley instructions). Just kidding.

^ Well, I'm not kidding anymore. ;) You know, I'm just a few centimeters away from moving the base. Just need a bit more time, patient and expertise :D

the ifupdown upgrade certainly changed *something*, but what i am not sure.
when i logged on today, didn't auto-connect. did 'ifup wlan0', it told me wlan0 was already configured. ceni still shows nothing.
did 'ifdown wlan0', it took down whatever it had put up (internet didnt work so not much). then 'ifup wlan0' again and it worked. wait more i suppose?
edit: oh yeah - output:

Ceni gets its list of available devices from udev (/lib/systemd/system/
[email protected]), it shows those devices that
sudo ifquery --state
lists. I really have no idea what the FUCK is going on in Disneyland again, but they definitely get on my tits.

Code: Select all
┌┤rhowaldt@lalala [~]
└──┤$ sudo ifquery --state
[sudo] password for rhowaldt:

lo=lo
but those are listed as optical devices or so in ceni. i dunno either, i am currently just uhm, "going with the flow", and being patient :)
