USC would disable any residential port trying to host a real server like that (i.e. not a game server or something). It's a research and education network, not your free ISP. If you have legitimate reasons, get a teacher's note and we'll let you. We watched the connection counts, we'll investigate the weird and probably disable your port and account and send you to Student Conduct. You have to fly under the radar, too many connections to other machines on inside (you're up to something), or too much traffic (you're up to something else). Then again, we were better at network than most other universities.
