Can somebody please tell me how to write a filter to capture :
FTP sessions, the username, the password and the files transfered in both directions?

For that you need to scan for the keywords GET, PUT on the FTP command
channel. Don't know exactly how username and password are transferred
(on that same channel, yes, but the keyword!).

Simply modify a FTP rule you already have.
