Using openvpn3 in Gitpod

[107ef363-c60f-46fb-a8bc-da8c5f4f6938]

I am trying to connect to an OpenVPN server from Gitpod. Since this client is designed to be run by unprivileged users, it seems like a great fit.

However I get this error when running openvpn3 session-start --config ${MY_CONFIGURATION_FILE}:

** ERROR ** Could not connect to the D-Bus daemon for : Could not connect: No such file or directory

I'm guessing I have to set up a D-Bus daemon manually to get it to work. Can anyone confirm this or correct me if it's something else?

I've never heard about anyone using it on Gitpod yet. But if you have dbus-daemon or dbus-broker running a system bus, this should work. But you need basic DBus functionality to use openvpn3-linux.

@dsommers Awesome! I'll link the Gitpod configuration once it's working. Thanks for the quick response!

@dsommers I installed dbus-broker and systemctl enable dbus-broker.service seems to be working (it successfully creates the link at /etc/systemd/system/dbus.service). But I'm still getting the same error.

** ERROR ** Could not connect to the D-Bus daemon for : Could not connect: No such file or directory

I'm still not sure what file exactly openvpn3-linux is looking for but clearly it's not where it is expecting it to be. Is there a way to point it to the correct location?

That error is a generic error message from the kernel, where most likely the D-Bus implementation is not able to find the socket applications use to talk with the D-Bus daemon. Can you try to use strace to see which open() calls fail?

[107ef363-c60f-46fb-a8bc-da8c5f4f6938]

@dsommers These two calls seem to be responsible:

connect(5, {sa_family=AF_UNIX, sun_path="/var/run/dbus/system_bus_socket"}, 110) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/usr/lib/x86_64-linux-gnu/charset.alias", O_RDONLY) = -1 ENOENT (No such file or directory)

[dsommers]

That looks like dbus-broker isn't configured to run a system bus. Or that some symlinks are missing. This is kinda out-of-scope for openvpn3-linux itself, as openvpn3-linux expects basic D-Bus functionality to be present. Try to use various standard d-bus tools (busctl, gdbus, d-feet, etc) to see if you can introspect system services.

[dsommers]

Closing this now, as this is not related to openvpn3-linux itself, but more a generic system issue.

did you ever get this working ? Hitting the same problem

[DiStefano8472]

I want to use it inside of a docker container. But I am running in the same issue.

Did you handle it?

Any workarounds to use this from docker?
