Have your laptop dial in to you with vital information when it gets stolen.
Version: 1.0When stolen, your laptop will report back to you vital network information (from AirPort, Ethernet and Bluetooth), plus a traceroute that can help you track where the laptop is, and screenshots as the thief is using your precioussss!
Operating System: Mac OS X
You put a shell script onto your laptop and schedule it to run every X minutes via a cron job. You put a PHP script on a webserver you own and control. The laptop then checks with your webserver to ask if it has been stolen. It usually receives a reply that indicates that everything is OK. If it's ever stolen, you would change a variable on the server, which sends a different reply to the laptop the next time it connects. If the laptop gets such a reply, it goes into 'reporting mode' and starts keeping track of network connections and starts taking screenshots. It sends both of these to your server. Those records will be stored on the server and you will receive an email.
This is a set of two scripts: a shell script, and a PHP script.
