MattiCheers,I'm somewhat worried how easily one can corrupt whole Linux system - just load files to /etc whose user is not a proper user of the installation! They can be loaded to other place, change owner there and load then tho /etc. Anyhow this is none of your worry, I suppose.There is no way back at this point. Whole system is corrupted. It does not help deleting /etc/openvpn directory and note that it is not needed to start openvpn service to get this triggered. Only way I have found to recover is re-install whole system!2) I uncompress/untar the archive that creates /etc/openvpn directory with openvpn cert/config files, user = original user.1) I load openvpn cert as zipped tar archive to root.The trigger:Lubomir, Dan,I found what triggers this issue. I don't know what the reason is, though! It has nothing to do with NetworkManager.2016-12-09 16:35 GMT+02:00 matti kaasinen <matti kaasinen gmail com>:Lubo,
It took some time before I had change to get to this issue again. I got new board and it did not start at all, so I had to study u-boot in between..
Anyhow, answers to your comments:2016-11-25 18:15 GMT+02:00 Lubomir Rintel <lkundrak v3 sk>:I'm not sure at all that I could concentrate on the correct details of these logs, though. So, I would really appreciate any suggestions.That sounds very strange.
Please enable eavesdropping on the system bus:
https://wiki.ubuntu.com/DebuggingDBus#How_to_monitor_the_sys tem_bus
And then monitor the actual bus traffic before starting the "openvpn
service" (is that the NM VPN plugin?) and after starting it and look
out for what changed.No. That is coming from Yocto/meta-openembedded/meta-networking layer. Just pure openvpn binary and systemd unit file for starting service. Only (main) difference I noticed from dbus-monitor log was that before openvpn I got following errors:
string "Could not get owner of name 'org.freedesktop.nm_avahi_autoipd': no such name"
string "Could not get owner of name 'org.fedoraproject.FirewallD1': no such name"
string "Could not get owner of name 'org.freedesktop.login1': no such name"
string "Could not get owner of name 'org.bluez': no such name"
string "Could not get owner of name 'org.freedesktop.ModemManager1': no such name"
string "Could not get owner of name 'org.bluez': no such name"
string "Could not get owner of name 'org.freedesktop.nm_dispatcher': no such name"
And after enabling openvpn service I got:
string "Could not get owner of name 'org.freedesktop.nm_avahi_autoipd': no such name"
string "Could not get owner of name 'org.fedoraproject.FirewallD1': no such name"
string "Could not get owner of name 'org.freedesktop.login1': no such name"
string "Could not get owner of name 'org.bluez': no such name"
string "Could not get owner of name 'org.freedesktop.PolicyKit1': no such name"
string "Could not get owner of name 'org.bluez': no such name"
string "Could not get owner of name 'org.freedesktop.nm_dispatcher': no such name" So, policy kit has vanished.What I noticed from systemd journal regarding ntp synchronization was:

Avahi was behaving pretty much the same besides that "Permission denied" message:
