In Ubntu 14.04, how can I connect to a vpn connection created through the graphical shell using a command in a .sh script?

Question

VPN

This "pon vpn" naturally produces:
The file /etc/ppp/peers/vpn does not exist. Please create it or use
a command line argument to use another file in the /etc/ppp/peers/ directory.
What command to enter in the script so that the button click will work (see figure)

Answer 1

nmcli con up id VPN
(VPN == connection name as is, it is better to use names without spaces).
You need to run from the user under which this connection was created (if not shared). For those who do not understand the phrase - NOT through sudo.
