""" Displays the VPN profile that is currently in use.
|
|
|
|
Left click opens a popup menu that lists all available VPN profiles and allows to establish
|
|
a VPN connection using that profile.
|
|
|
|
Prerequisites:
|
|
* tk python library (usually python-tk or python3-tk, depending on your distribution)
|
|
* nmcli needs to be installed and configured properly.
|
|
To quickly test, whether nmcli is working correctly, type 'nmcli -g NAME,TYPE,DEVICE con' which
|
|
lists all the connection profiles that are configured. Make sure that your VPN profile is in that list!
|
|
|
|
e.g: to import a openvpn profile via nmcli:
|
|
sudo nmcli connection import type openvpn file </path/to/your/openvpn/profile.ovpn>
