Scenario: The ship has a linux computer, you want a desktop screen capture that you can view on your own local computer.

Names:

• shipuser@shiplinux
• landuser@landserver
• me@mycomputer

## landuser@landserver must be able to ssh into shipuser@shiplinux Set up a ssh key so this is automatic.

## me@mycomputer must be able to ssh (with a key) into landuser@landserver

Make a bash script that looks like this:

## begin remote_screenshot.bash ##

#!/bin/bash
## store the image in ~/tmp
## image will be called "screenshotX.png"
cd ~/tmp; DISPLAY=":0.0" import -window root screenshotX.png

## give a clue
echo "on ship: desktop captured in ~/tmp/screenshotX.png"
