I was working with a customer that REQUIRED all VNC connections go over an SSH Tunnel…

After Googling around a bit, I found how to do it but I wanted to my a script to automate the process in case I run into this in the future.

Here it is…

# Establish SSH Tunnel for VNC on OSX

{
	clear screen
	echo "########################################################"
	echo "SSH Tunnel for VNC Viewer                               "
	echo "########################################################"
	echo
