Anatomy of an Auxiliary Module
Let’s look at the makeup of an auxiliary module in a fun little example not currently in the Metasploit repository (because it does not pertain to penetration testing). This example will demonstrate how easy it is to off-load a great deal of programming to the Framework, allowing us to focus on the specifics of a module.
Chris Gates wrote an auxiliary module for the Framework that gave his Twitter followers the impression that he had somehow invented a device that allowed him to travel at the speed of light. It makes a great example of the code reuse available in Metasploit. (You can access the source of the script at http://carnal0wnage.googlecode.com/.)
