Ok, so I have been using BT for a while now with no problems. Now, all of a sudden, my university starts blocking it.
First, they write a J4vaScript to intercept my actually downloading the .torrent file. I can easily get around this, but its an annoyance nonetheless.
Next, they blocked the normal BT ports, 6881-6999. Once again, I have no real problems there. I just have to find a port range that isnt blocked (which takes time) and randomize the port usage of each individual client.
Now, onto my trouble. All of these prior methods of screwing me over I have found out on my own; they obviously wouldnt tell me this stuff. However, I think they are reading my packets being sent and recieved. And, if not the whole packet, then just the headers.
I can sometimes actually connect to the tracker, and even start to download from other people. However, after that, they just disconnect me. Now I am starting to panic...I havent been able to download anything in almost two days! Furthermore, I dont even know if this is some sort of temporary thing for uploading over 16GB per day last week; or if this is a permanent part of their new network policy.
Anyway, I guess my question is something like: Is there anything I can do to get around this last line of defense my university has emplaced?

If they want to look at your traffic, they can see any-fuking-thing they want. They can also cut off your connections, which it sounds like they might already be doing.
I'd say the 16gb/day fuked you right over.
Maybe there are dorms or machines they're not monitoring which you could (gently) use to download on.
Most importantly, go make a friend in the IT department and ask him what/why/how; maybe you can gleam some clues on ways to get around it.

Well, I know that they use our MAC addresses when you first try to connect to the network at the beginning of the year...I was thinking maybe I could change mine to someone else's if this ban is against myself specifically.
I mean, I doubt they have the time to sit and go through all the packets being sent and recieved over our network. But, now I'm kinda thinking that they must just randomly go through the headers, because I can actually connect and start downloading.
Maybe some sort of encryption would work best.

You can change MACs, and that might get you somewhere. If you're behind a switch, though, it's going to be child's play to know exactly which port is feeding which drop.
It's probably very easy for them to lock onto who is using lots of bandwidth, so encrypting is just going to confuse them for a couple seconds before they go "heavy load, fuk this guy" and snip your connection.
The good news is, this may all be a human process. If it's not super-automated, and you lay low for a few weeks, maybe they'll forget about monitoring the traffic.
But I'd let that 16gb/day shit go right quick, unless you just want to try your chances.

Yea, so either I lay low or I stop altogether. Either way I'm more or less fuked. Especially if they targeted me personally. This really sucks ass though...I guess I'm left with using my home cable modem to download onto my home box and then upload it to my school box.
Thanks anyway vas.

i'm assuming you can ftp or download from http sites fine, right?
here's what you do:
zip a copy of your windows directory or something similarly large.
send that fucker to your home machine to the tune of 15 GB a day.
see what happens.
that's all i gots. |

Would changing yer torrent client make a differance or do they all send teh exact same message? What about a kazaa type app?

Nah, changing my client wouldn't really do much in the way of monitoring. As vas had pointed out, they would just see that there was a heavy load going to and from my ip, and my connection would be cut. In hindsight, I guess 16GB/day was a little much.
Today I actually went to teh computer services department and danced around the issue of p2p, trying to gain some knowledge. After talking to the computer security guys, they basically said that I would recieve a warning, then they would close the ports the program was using, and finally they would cut my connection. As much as I wanted to come out and ask why they closed my ports, I figured that was the wrong thing to do.
The security guy said that they dont do any intrusive monitoring, like packet filtering, but they do monitor the bandwidth load and the like. He also said they dont write their own software when it comes to sys-admin stuff, so I guess that limits their abilities.
I figure I'll lay low for a week or two and see if the ports are still blocked. If they are, I'll just claim it was wrongfully done. If they ask about the ports being used, I'll say I was using a legitamite program like mIRC or something.
Interestingly enough, when I first mentioned p2p, no one said anything about BT. I cant decide whether they had ever heard of it, or if they are still working on blocking it and dont want to give me the idea of using it.
