Spying on your victim with Screenspy of Metasploit in Ubuntu!

Screenspy is a feature in Meterpreter which allows you to view what your targeted host is doing on his workstation.  It captures the images on your targeted host, sends it back to you on a set interval (in seconds) and you will look at it as if its live on your local machine.
