openvpn/networkmanager: dbus message rejected errors on connect #24806

Closed benley closed 5 years ago

Issue description

Trying to set up an OpenVPN connection using the NetworkManager gui (in plasma5, but in theory it should be the same as in gnome, right?), and connections are failing immediately after a successful connection with the following error messages in syslog:

dbus[2381]: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.129" (uid=217 pid=22761 comm="/nix/store/57gfjpm4mb689p0ih6jv90l3rnjclhna-Networ") interface="org.freedesktop.NetworkManager.VPN.Plugin" member="SetConfig" error name="(unset)" requested_reply="0" destination=":1.124" (uid=0 pid=22461 comm="/nix/store/57gfjpm4mb689p0ih6jv90l3rnjclhna-Networ")

nm-openvpn[22464]: Initialization Sequence Completed
nm-openvpn[22464]: Connection reset, restarting [0]

Then the connection starts again and it repeats forever.

Technical details

Does the nm-openvpn user need to be added to the networkmanager unix group for this to work?

benley commented 7 years ago

The connection reset in my log snippet may actually be caused by https://github.com/NixOS/nixpkgs/issues/24808 but I suspect that the dbus rejected sends are still a problem.

Any news on this issue?

benley commented 5 years ago

I don't think I have encountered this bug for quite a while, but I also haven't been using OpenVPN recently. Are you still seeing the same error messages?

mmahut commented 5 years ago

I did not, just doing triage. I'm going to close this, but feel free to reopen it if it surfaces again.
