I think I have found the issue to this bug. If this is the same issue, it is related to the fix in commit 004a050

Hey, and sorry for the delay. I've been out of office for a bit, so didn't have time to dig into this before now.

The log lines here which looks like is causing this issue is:

 [...] net.openvpn.v3.netcfg[927]: Error while executing NetlinkRoute4(add: 1) ens33: -17
 [...] net.openvpn.v3.sessions[927]:   what():  Failed retrieving property value for 'device_path': The name :1.118 was not provided by any .service files

It would be good to ensure you're running the right versions of all the backend services required in OpenVPN 3 Linux. Can you please provide the output of:

sudo openvpn3-admin version --service

If all services uses the same v7_beta reference, that's a good starting point. Next then is to increase the log level:

sudo openvpn3-admin log-service --log-level 6

and then try again. And when failing, extract the log data like this:

sudo journalctl -u dbus --since today SYSLOG_IDENTIFIER=openvpn3-service-logger

And a final notice, you do not need to sudo the openvpn2 and openvpn3 calls. OpenVPN 3 Linux allows unprivileged users to start VPN sessions and manager their own sessions. If you want root to be able to manage a session you started as an unprivileged user, have a look at openpvn3 session-acl(1)

@dsommers Wow it works!!
Sorry for delay and thank you so much for your work.
Finally I can connect my company's VPN with my linux laptop!!

[dsommers]

Good to hear this release works for you!

The v8_beta was released on just a few days ago with this fix, so I consider this issue resolved.

[isac322]

Hi @dsommers, also sorry for delay. It was holiday on my country.

Output of sudo openvpn3-admin version --service:

OpenVPN 3 D-Bus services:

  - Client backend starter service
     openvpn3-service-backendstart: v7_beta

  - Configuration Service
     openvpn3-service-configmgr:    v7_beta

  - Log Service
     openvpn3-service-logger:       v7_beta

  - Network Configuration Service
     openvpn3-service-netcfg:       v7_beta

  - Session Manager Service
     openvpn3-service-sessionmgr:   v7_beta

And because sudo journalctl -u dbus --since today SYSLOG_IDENTIFIER=openvpn3-service-logger prints -- No entries --,
I tried sudo journalctl -u dbus --since today SYSLOG_IDENTIFIER=net.openvpn.v3.log and it prints

This looks like your server requires 2FA, which I think this client does not support yet.

This looks like your server requires 2FA, which I think this client does not support yet.

@schwabe If 2FA doesn't work, it's a regression. I'll retest this with my test server. But that should work.

@isac322 From the log entries you reported now (good job finding the other SYSLOG_IDENTIFIER), it looks like everything is connecting as it should - and it is now the server rejecting the connection. The initial log had some more critical issues where one of the backend services (openvpn3-service-* processes), so unless that appears again - then I have a hunch it was some old versions of one or more of the openvpn3 services running - but you probably rebooted since last time, so that environment is long gone. By the way, is it an Access Server you are trying to connect to?

[isac322]

@dsommers When I set SYSLOG_IDENTIFIER to net.openvpn.v3.sessions, it still prints:

(FYI. as you can see in timestamp, it is related with the last log that I post, not a separated one)

Because I paused the VM after the first issue instead of reboot, I guess the environment still exists and let me know if you need those.
Yeap I'm trying to connect Access Server and its version is 2.6.1.

I guess this is full log of openvpn3 session-start --config client.ovpn

I am now fairly confident these comes from the openvpn3-service-client process, and this is the most tricky part to get a core dump out of. And I believe this process crashes/dies; due to this error by the session manager:

Failed retrieving property value for 'device_path': The name :1.145 was not provided by any .service files

To get further, without fighting whatever coredump setup you have on your Linux distro ... lets start this process step by step via Python. This will be a "quick debugging with GDB crash course". First, ensure you have gdb installed on your system, then import the VPN configuration profile into the configuration manager unless you have done so already:

$ openvpn3 config-import --config client.ovpn

Since you connect against an Access Server, you can also do it this way:

$ openvpn3-as https://as.example.com/

where the https://as.example.com/ is the proper URL to your Access Server.
To see already imported configuration profiles, use openvpn3 configs-list

This returns a Configuration path which we will use next. The Python script below is needed:

import dbus
import sys
import time
import getpass

if len(sys.argv) != 2:
    print "Usage: %s <config path>" % (sys.argv[0])
    sys.exit(1);

configpath = sys.argv[1]

# Get a connection to the system bus
bus = dbus.SystemBus()

# Retrieve the main session manager object
manager_object = bus.get_object('net.openvpn.v3.sessions',
                           '/net/openvpn/v3/sessions')

# Retireve access to the proper interface in the object
sessions_interface = dbus.Interface(manager_object,
                                  dbus_interface='net.openvpn.v3.sessions')

# Start a new tunnel session
session_path = sessions_interface.NewTunnel(dbus.ObjectPath(configpath))
print("Session path: " + session_path)

time.sleep(1.2)

Start this script like this: $ python3 debug-vpn.py /net/openvpn/v3/configuration/.......
The line above is the line where you use the configuration path from the openvpn3 config-import.

When this script starts, you will see something like this:

Session path: /net/openvpn/v3/sessions/3869ec90s37cbs49aasb5fbsd47c036f11e3
Press enter to call Connect() ...

Do not "press enter" just yet. Run the openvpn3 sessions-list command, where you will see a PID value. Use this one and attach GDB to it. If the sessions-list says your session runs with PID: 1234, then your command line will be gdb --pid 1234. The gdb command needs to be run as root.

Once gdb has started, type cont and hit enter in the gdb window. Now you can hit enter in the the window of the Python script, which will take it one step further. You will probably need to enter your user credentials and hit enter a few more times before you see the crash in the GDB window.

When the a crash (segfault, abort, etc) happens in the GDB window, you will ge the gdb prompt. Now type: thread apply all bt (hit enter until you're back to the gdb command prompt) and please provide the output from gdb. This will help me understand where and hopefully why openvpn3-service-client crashed.
