Do those things generally block things like Kazaa also?

I'd say so. KaZaA usually uses a certain port (1214, IIRC) so it's rather easy to block it on a firewall.

Any firewall with a default-deny policy will block file-sharing services. If I wanted to set up a really secure large intranet for a bunch of students, I'd use HTTP and FTP proxies and then disable packet forwarding entirely. Slam the door down.

I'm not sure how they did it, but the assholes at my uni throttled the bandwidth on p2p networks down to like 50 bytes/second. Cockstains. Glad I'm not gonna be living on-campus anymore.

Are you sure that's 50 BYTES persec or 50 KBs?
50 bytes/s less than a 2800 baud modem can get.

That's not a typo, 50 bytes/second as in .05 kb/second. It took days to get an .mp3

Yep, they did the same thing in our school when everyone used AIM and KaZaA. Only us with a marginal bit of network skills could get past (They weren't that hard, they were just impossible for the normal kid to get past if they didn't know anything about computers)

Yes! Our firewalls block MIRC/KAZAA/ICQ and just about anything else we can find.

It's not to be mean to students. They don't realize that there is just so much bandwidth to go around. We went through this war year before last on campus.

On our campus, Internet access is provided at no additional charge to the students. They can purchase a nic card if they don't have one and they are provided the logon name and password. The only charge is a five dollar computer serivces charge.

Our Internet service, for the most part, is paid for by the state so we have to follow certain guidelines from the state when it comes to access.

Students living in the dorms do have the option of getting their own private DSL service or using our service.

Luckily, UT doesn't block much of anything. I have yet to find anything that is actually blocked, anyways, I use Direct Connect to download anything I get, and, it being one of the lesser known P2P proggies and using a different kind of format that doesn't have a centralized server, I doubt it will be locked down very soon.

It's called packet shaping. The system can look at various packets and decide which ones get priority (usually basic HTTP and FTP traffic) whilst slowing down things like P2P.

Most universities implement it so that real traffic can get through (at Northwestern, until they put in packet shaping their multiple OC-3 lines were being overloaded)

My school is plugged directly into the backbone (OC-192). No bandwidth issues there. It's because they were afraid of being sued by the forces of evil (aka the RIAA)

Our policy was initially developed back when there were definite bandwidth issues. Actually, it still is with our wireless network. It all esclated when the lawsuit issues came into play.

Actually, I totally agree with a lot of our policy because my team is the one that has to deal with all the problems that arise from misuse of the resources. My problem with it is that it's not everybody that abuses things, but everybody has to pay. It's too bad that couldn't be changed. He have tried a few times a easing some restrictions, but it's only a matter of a couple of weeks before we find ourselves putting them back into place.
