Traditionally, FTP servers run on port 21 – but really you could put one on whichever port you feel like. Skype is going to be quite a bit harder.Īnyhow, here is what I’ve found out about FTP… FTPįTP runs over a TCP connection, so if you’ve got Telnet, then you’ve got a basic FTP client. If it matches, chances are we’ve determined what kind of server is behind that IP/Port.įTP and HTTP are the trivial ones. If we get a response, we analyze the response to see if it matches what we expect from the signature. The big idea: we want to create some signatures, and then “replay” those signatures against some arbitrary IP and port.
