Ensure that the following values are set:

Autofs on Mac OS X

With autofs you can easily mount network volumes upon first access to the folder where you want to mount the volume. Autofs is available for many OS and is preinstalled on Mac OS X so I show you how I mounted my iTunes library folder using this method.

Prepare autofs to use a separate configuration file

autofs needs to be configured so that it knows where to gets its configuration. Edit the file /etc/auto_master and add the last line:

#
# Automounter master map
#

+auto_master # Use directory service

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

	var Accessory = require('../').Accessory;
	var Service = require('../').Service;
	var Characteristic = require('../').Characteristic;
	var uuid = require('../').uuid;
	var ping = require ("net-ping");
	var http = require('http');
	var url = require("url");
	var util = require("util");

	var wsUrl = "ws://IP_ADDRESS_HERE:3000";

	-- 1. Create a new generic password entry in Keychain Access called "WHATEVER_AnyConnect_VPN" (the name in Keychain access must match that in line 39 below) with your password for the Cisco AnyConnect VPN server.
	-- 2. Open this script in Script Editor (both this and the above are in the Applications->Utilities folder) and "Save as.." an Application (.app) with desired name.
	-- 3. Open Security & Privacy System Preferences, go to Privacy, Accessibility.
	-- 4. Enable the above .app so it can access Accessibility
	-- 5. Copy and paste a nice icon on the generic Applescript icon (I used a copy of the default AnyConnect one)
	-- 6. Add the new .app to /Users/[yourshortname]/Applications with a shortcut to your Dock
	-- 7. Enjoy the fast connection with no need to enter password and increased security of not having a sensitive password stored as plain text
	-- 8. Run script again to close connection

	-- AnyConnect now refered to as targetApp
