Applescript to Automatically Connect VPN

Recently got a MacBook and when I'm at home I use it to connect to my university's VPN connection. This works well except for the fact that it disconnects every time my laptop sleeps or locks so I wrote this applescript:

on idle

tell application "System Events"

tell current location of network preferences

set myConnection to the service "VPN University"

if myConnection is not null then

if current configuration of myConnection is not connected then

connect myConnection

end if

end tell

return 120

end tell

end idle

I also edited the info.plist so that the application was completely hidden at all times. This works well whilst I have the ethernet cable attached and want to be on the VPN, but as soon as I move away from my desk I want to be on the wifi and the continuous 'failed to join VPN' error messages are quite annoying.

I was wondering if there was an applescript workaround that would somehow test whether I have the ethernet cable attached? I realise I may be asking a bit much.

Thanks.

MacBook Pro with Retina display, OS X Mavericks (10.9.4)

You can check whether a particular interface has an ip address set, so that will probably do what you want. This illustrates one way of checking whether ethernet or wifi is live:

set ethernet to do shell script "ipconfig getifaddr en0; exit 0"

set wifi to do shell script "ipconfig getifaddr en1; exit 0"

if ethernet is not "" then

display dialog "ethernet connected"

else

if wifi is not "" then

display dialog "wifi connected"

end if

Okay that's interesting I hadn't thought of that. Forgive me though as I'm new to Applescript: how might I combine the whole lot into one script?

Thanks.

I think you just need to wrap your whole script in a test to see whether ethernet is connected:

on idle

set ethernet to do shell script "ipconfig getifaddr en0; exit 0"

if ethernet is not "" then

tell application "System Events"

tell current location of network preferences

set myConnection to the service "VPN University"

if myConnection is not null then

if current configuration of myConnection is not connected then

connectmyConnection

end if

end tell

return 120

end tell

end if

end idle

For maybe a year I (novice script'r) wrote, & had working, w/ google's help, a simple VPN connect script, when I upgraded to El Capitan, (seen below) my script quit working - can someone please paste something in here that will work with El Capitan so I can have my 1 click functionality back?

This won't work with IKEv2 VPNs. Here's how you can do that: http://matt.coneybeare.me/how-to-setup-an-auto-reconnect-script-for-an-ikev2-vpn -service-on-your-mac/
