Openvpn and NetworkManager

Openvpn and NetworkManager

Hi,

I'm trying to get openvpn and the NetworkManager plugin to work together
but I am having some troubles.

I started with installing both packages, but the openvpn plugin specific
menu options did not show up in the connection menu.

I read the documentation and noticed the "vpn-plugins" option in the
network-manager service declaration, so I added the network-manager-openvpn
service like this:

(modify-services %desktop-services
         (network-manager-service-type config =>
                                       (network-manager-configuration
                                       (inherit config)
                                       (vpn-plugins (list
network-manager-openvpn)))))))

After that, it now shows up and I can import openvpn connections (I noticed
it added a NM_VPN_PLUGIN_DIR environment variable) but I cannot connect.
When I click connect simply nothing happens, and the following log is
emitted to /var/log/debug

Dec 23 23:09:49 localhost NetworkManager[345]: <info>  [1514070589.5044]
audit: op="connection-activate" uuid="36c09127-ffc0-4d46-9547-06e0ea214a15"
name="mullvad_de" pid=470 uid=1000 result="fail" reason="The VPN service
'org.freedesktop.NetworkManager.openvpn' was not installed.

I researched the error message and it seems common when people don't have
plugin installed (obviously), but I also found this:
https://github.com/NixOS/nixpkgs/issues/3539 which might be related.

I'm pretty new to guix and scheme so any help would be greatly appreciated

Just to be sure: have you only noticed this variable or have you sourced
the new .guix-profile/etc/profile where it should be included?

I have opened a bug about this a while ago (OpenVPN and the (not yet merged?)
VPNC plugins are affected. It's annoying prevents me from accessing my university
intranet via VPN for some things from home.
Maybe it was just an email so far, I can not find a bug ticket for this.

Thanks for the additional issue, I didn't look into Nix so far.

Not 100% sure what you mean but the following is in the output of "env" :
NM_VPN_PLUGIN_DIR=/gnu/store/1k98ck98lirfw9974qvz84xikcsjc67f-network-manager-openvpn-1.8.0/lib/NetworkManager/VPN

If I can help by providing any more logs or something I'd happy to do that.

Could you try “groupadd -r networkmanager && usermod -aG networkmanager root”
(these changes will be lost upon reboot) and run “nmtui” from there?

Thanks,
Ludo’.

This does not fix the problem, the problem persists also after "sudo herd
restart networking", the message is still "Could not activate the
connection: The VPN service 'org.freedesktop.NetworkManager.openvpn was not
installed'"

Querying /var/log for "vpn" returns many entries like this:

/messages:Jan 11 13:24:50 localhost NetworkManager[19464]: <info>
[1515673490.8272] audit: op="connection-activate" uuid="not sure if this is
sensitive information but i removed it anyways" name="mullvad_de-ber"
pid=19581 uid=0 result="fail" reason="The VPN service
'org.freedesktop.NetworkManager.openvpn'
was not installed."


I will investigate further later, but I am not sure where to start

Could you see what operations triggers those warnings?  Is it when you
run ‘nmtui’ or similar?

Thanks,
Ludo’.

Yes, it happens when I try to activate the VPN connection in nmtui,  and
also when I try to activate the vpn connection via the gnome vpn ui.
Its puzzling me, since the plugin seems to be installed correctly as it
shows up in the gnome ui.
