TightVNC...

If you know what a VNC is then you can skip this explanation.

To put it simplistically it is remote administration or operation of your computer, via networked computers..  In my case, the truck computer has a wireless network adapter, and external antenna.

The truck computer runs the TightVNC server program,(it is in the download, standard install program)  it patiently sits there running in the background.  I run the TightVNC client on the home computer and connect to the truck.  Now I have a window that shows the truck computer desktop on it...and I can do anything to it that I could do if standing next to it.

This picture was a test...I used TightVNC to access one computer, then used TightVNC on that computer to access the truck computer.

There was no problem in the setup...very straitforward....if you understand networks at all.
