Metasploit Decloak v2

[hdm at metasploit.com (H D Moore)]

This project is designed to cut past proxies and identify a user's real 
source IP address and network. The new version works with Flash 9 security 
restrictions, fixes a JVM hang on Linux, and adds a few new detection 
methods. It uses no javascript and is a great test of your Tor/Proxy 
configuration
