And on the landside server, make this script to execute screenshotX.png on the ship, and rsync the file back. Call this one **remote_shipX_screenshot.bash** | And on the landside server, make this script to execute screenshotX.png on the ship, and rsync the file back. Call this one **remote_shipX_screenshot.bash** | ||
+ | ## begin script to get the screenshot back to the landserver ## | ||
+ | #!/bin/bash | ||
+ | ## works best if there is an ssh key on the remote machine | ||
+ | # - make the remote command for screenshot | ||
+ | # - this example requires a port to log in | ||
+ | | ||
+ | ssh -p ##### shipuser@shipserver / | ||
+ | | ||
+ | ## bring it back, put it in /tmp | ||
+ | echo " | ||
+ | rsync -Pv -e 'ssh -p 56565' shipuser@shipserver: | ||
+ | | ||
+ | ## move it to the location of choice | ||
+ | mv / | ||
+ | | ||
+ | Test it by running | ||
+ | **/ | ||
+ | and view the png | ||
+ | |||
+ | ====Step 3: Wrapping with an HTML==== | ||
+ | |||
+ | Now if you are on the landserver you can look at the png file. If you want the png served up on a web location, you can look at it directly. If you want an html to wrap it, so it refreshes every so often, | ||
+ | put this in the same location as shipuser_screenshotX.png: | ||
+ | |||
+ | **shipuser_screenshotX.html** | ||
+ | |||
+ | ##begin html file to display shipuser_screenshtX.png ## | ||
+ | < | ||
+ | < | ||
+ | <meta http-equiv=" | ||
+ | < | ||
+ | < | ||
+ | <img src=" | ||
+ | <br> | ||
+ | <br> | ||
+ | <br> | ||
+ | </ | ||
+ | | ||
+ | Then you can browse to this page and it will refresh every 5 min: http:// | ||
+ | |||
+ | |||
+ | ====Step 4: Creating a cronjob==== | ||
+ | |||
+ | Make the <color # | ||
+ | hourly at 10 min past the hour. | ||
+ | |||
+ | **NOTE:** crontab does not have a good environment so if you need to set your PATH, do so in a bash_env file and source that before running the command. That's how I did it. Or be very explicit about setting your PATH first.This is all **one line**: | ||
+ | |||
+ | 10 */1 * * * (date +\%F\ \%T; cd / | ||
+ | / | ||
+ | | ||
+ | **Another note:** I also outputted the stdout to a log file. | ||
+ | |||
+ | ====Step 5: Running from your laptop==== | ||
+ | |||
+ | ssh landuser@landserver / | ||
+ | | ||
+ | or make an alias: | ||
+ | |||
+ | alias get_shipX_screenshot=' | ||
+ | "view this file"; echo ""; | ||
+ | | ||
