How to disconnect from OpenVPN?

  • 772

I'm connecting using VPNBook servers and it works fine with this command:

 sudo openvpn --config /etc/openvpn/vpnbook-udp-53.ovpn --auth-user-pass /etc/openvpn/password.txt

but I just can't seem to figure out how to stop it without a reboot.

I've tried service openvpn stop and /etc/init.d/vpnbook stop, but that doesn't seem to affect it.

  1. This command definitely works for me, and it should work for you too.

    sudo killall openvpn

  2. I had same problem with disconnecting from openvpn3

    I end up creating this small repo that helps manage the openvpn3 sessions

    To disconnect the session, you have know the session's Path

    openvpn3 session-manage --session-path $OPENVPN3_SESSION_PATH --disconnect

    the session path could be found via

    openvpn3 sessions-list

> -----------------------------------------------------------------------------
>         Path: /net/openvpn/v3/sessions/7a42f37asc8d9s424c8b534sd331d6dd56e8

>  Config name: client.ovpn  (Config not available)
> Session name: ***.***.***.***
>       Status: Connection, Client connected

    OPENVPN3_SESSION_PATH=/net/openvpn/v3/sessions/7a42f37asc8d9s424c8b534sd331d6dd56e8
openvpn3 session-manage --session-path $OPENVPN3_SESSION_PATH --disconnect

    You can use my repo to perform same actions with help of bash files.

  3. The successful steps in my case were:

    # stop the service    
$ sudo /etc/init.d/openvpn stop

# find the process if it is still running for some reason
$ lsof -i | grep openvpn

# kill the proccess(s) by its PID
$ kill -9 <PID>

# if necessary restart the service again
$ sudo /etc/init.d/openvpn start

    For some reason killall -SIGINT openvpn did not work for me, but the steps above did.

  4. I stumbled upon having 2 open sessions with the same config path. So I could not use

    openvpn3 session-manage --disconect --config <config_path>

    session-manage: ** ERROR ** More than one session with the given configuration profile name was found.

    So I made a script to loop through sessions (session ids are not always the same as the config paths)

    ACTIVE_SESSIONS=$(openvpn3 sessions-list | grep -i 'path' | awk '{p=index($0, ":");print $2}')
echo $ACTIVE_SESSIONS
for instance in $ACTIVE_SESSIONS; do
    openvpn3 session-manage --disconnect --session-path ${instance}
done

  5. Try this

    killall -SIGINT openvpn

    You can get more info on the different signals you can send here.

  6. In case sudo killall openvpn does not finish the job (I experienced it a few times) then a sharp and fatal solution would be:

    pgrep openvpn | xargs sudo kill -9

  7. Just hit CTRL+C in the terminal you just started OpenVPN.

  8. after running sudo killall openvpn or service openvpn stop the virtual interface "tun0" would remain opened and referenced in route table, so actually related connections would be lost since openvpn service is killed.

    the solution is to delete this virtual connection after killing openvpn service, as it is created everytime when openvpn service gets connected.

    so you need to run below commands for disconnecting openvpn:

    $ sudo killall openvpn
$ sudo ip link delete tun0

  9. sudo openvpn3 session-manage --disconnect --config $'client'.ovpn

    Replace client with the corresponding name.
    This will shutdown the session.

  10. Use the following command, where 0 is the tunnel number:

    sudo ifconfig tun0 down
