This is probably unrelated to this bug, but the whole networking stuff seems to be kinda mess right now (at least to people not deeper involved in both (ifupdown + systemd)... we still have networking.service, we have network.target, we have the ifup@.service... and I'm sure NM also has some service file (though I couldn't find it too hook in before network.target... Shouldn't the legacy sysvinit scripts go away,... and everything (including allow-auto/auto) be handled by a unit file proper? > "auto" interfaces are handled by /etc/init.d/networking, which is > shipped by ifupdown. Therefore re-assigning to ifupdown. Well as I've noted in my mails from yesterday... even with allow-hotplug there are still several things that don't work (i.e. services are being started before they can bind to the addresses)... Isn't this then something in systemd? Or is it rather a problem in the respective service's unit files? But at least apache and sks still use sysvinit legacy mode... so it probably cannot be their fault. Yesterday I've told you that I placed some cron job which is meant to restart the network+ssh every 10 minutes or so... and if this doesn't work he changes /e/n/interfaces to allow-hotplug and reboots. Attached is that script + it's logs, so that you can see what happens from that side. It's basically doing this: network-restarter.log is the main log, here with entries from two runs: 1st run: when the system was up and I connected to it and changed to allow-auto, but networking was still ok then I rebooted, the system did boot, but networking didn't come up again 2nd run: the script found that networking is down, and tried several things to bring it up again,... the output from these things and from ifconfig is in network-restarter.log.2. > Regarding logs: It would probably be helpful to boot with > systemd.log_level=debug and attach the output of journalctl -alb all attached + syslog from the last n runs... not sure if all the previous tries are helpful though,.. I did replace some privacy related stuff (ip addresses, domain names)... hopefully I didn't miss some private keys in my logs ;) > and > specifically the output of systemctl status networking.service. this is in the network-restarter.log.2 Cheers, Chris.
