Demo of measuring the time it takes a server to close a connection utilising the FTP PASV

vulnerability in firefox. Banner grabbing will be performed against 127.0.0.1 on ports

21,22,23,25,80,139,445,1433,3306,5432,6881. Ensure that you some of these services open

(ssh and mysql are best). Banner grab will take a really long time - you will normally

see some results within 5-6 mins

Refer to http://bindshell.net/papers/ftppasv for full details of how this works.
