I'm on a college network, and everyone connects to everyone elses computer to download stuff. Well, uh, I have some, umm, legal files shared, no illegal piracy going on here. Problem is, there are a few leeches on the network who download like 10 gigs of legal files and don't share anything in return. So, instead of allowing them to do this which then slows down my computer, I want to ban them I can use smbstatus to see who's downloading, use tcpdump to get their IP, but how would I go about banning them from connecting via SMB to my shared files? Thanks
