Replying to file sharing on campus

alright, i get to my dorm and no file sharing programs work. it seems as though the campus network is equipped with some kind of port blocking to protect from viruses, security issues, but it stops all the filesharing programs that i know of from being able to communicate with others on the web of hosts and exchange files. does anyone know what i can do to defeat this possible destuction of my ability to excercise my free use rights to swap files with my fellow music lovers. please don't tell me that i'm screwed, there must be some way to break this damn thing.
