Get Information of User download files from torrent

Hi

Hi,

I have been using hotspot, PPoE and Freeradius , I would like to know how I can Get the information of Which user is downloading Torrent files . I want to store User Download details in database. Because of some user downloading Copyrighted Movie from torrent . We need to know who is downloading and warn them .

Thanks

Almost impossible. Traffic is encrypted so you cannot know. Maybe by number of opened connections and used port analysis. But it is just guess.
