Tunnelblick Connection & Authentication via Script

[Alex Massey]

Hi, I am trying to mimic what I can do on the windows and linux OpenVPN client where I can control the VPN connection via script. I have found a script I can use to connect to an existing VPN connection, however I want to be able to supply a configuration file and connect to it with authentication from an external app without any interaction from the user on Tunnelblick. 

Currently on the Windows OpenVPN client for instance I can temporarily write the username/password to a file, pass the configuration file to the executable via a single command and it will read the credentials and connect then I can safely delete the file. How can I go about mimicking this setup using Tunnelblick? 

Currently I'm using the following script to at least connect however I need to automate the credentials as well as the user won't know what their credentials actually are.

tell application "Tunnelblick"

connect "TUNNEL1"

get state of first configuration where name = "TUNNEL1"

repeat until result = "CONNECTED"

delay 1

get state of first configuration where name = "TUNNEL1"

end repeat

end tell

Thanks

(Sorry for answering this so late. Perhaps my answer will help someone else with this question.)

Two ways to do it:

1. You can use OpenVPN's --auth-user-pass file option. file is a file contains the username and password, each on a line terminated by a LF character.
   
2. You can save the credentials in the KeyChain and set a Tunnelblick per-configuration preference to indicate they are available.
