You can launch gopenvpn manually
... or add it to your GNOME session's startup items so that it starts up whenever you login to your computer.
Once gopenvpn is loaded, its system tray icon will appear. The tray icon appears RED when no connection is active, YELLOW and blinking when a connection is being made, and GREEN when one or more connections is active.
Right-click on the tray icon to display the gopenvpn context menu. The context menu lists all the VPN connections available to connect, as determined by gopenvpn's scan of the /etc/openvpn directory for OpenVPN configuration files.
The OpenVPN log for each connection can be viewed in the Details dialog box, accessible from the "Details..." menu item on the context menu.
The Details dialog box permits you to tab between connections, reviewing the log for each, and can also connect/disconnect connections and edit the configuration files.
