Wie erstelle ich eine VPN-Verbindung über ein Terminal?

Sie können diese wunderbaren Bash-Funktionen von @slhck bei Super User verwenden :

Um sich mit verschiedenen VPNs zu verbinden, müssen Sie mehrere VPNs in Network.prefpane haben.

function vpn-connect {
/usr/bin/env osascript <<-EOF
tell application "System Events"
        tell current location of network preferences
                set VPN to service "UniVPN" -- your VPN name here
                if exists VPN then connect VPN
                repeat while (current configuration of VPN is not connected)
                    delay 1
                end repeat
        end tell
end tell
EOF
}

function vpn-disconnect {
/usr/bin/env osascript <<-EOF
tell application "System Events"
        tell current location of network preferences
                set VPN to service "UniVPN" -- your VPN name here
                if exists VPN then disconnect VPN
        end tell
end tell
return
EOF
}

^{Vergessen Sie nicht, den Namen des VPNs zu ändern.}

scutil sollte alles sein, was Sie brauchen.

scutil --nc start <service name>

Ihr Python-Skript, mit dem Sie sich nacheinander verbinden, kann also Folgendes enthalten:

import re
from subprocess import call, check_output

vpns_string = check_output(["scutil", "--nc", "list"]) # lists all VPN services

vpns = re.findall('"(.+)"', vpns_string) # service names are double-quoted

for vpn in vpns:
  call(["scutil", "--nc", "start", vpn])
  #...do stuff with your connection, test speed etc.
  call(["scutil", "--nc", "stop", vpn])

Sie können optional Benutzername, Passwort und Geheimnis angeben, mit dem Sie sich verbinden möchten - siehe scutil --nc helpVerwendung.
