Packet shaping

The college I attend uses packet shaping and I was wondering if there is a way to get around that feature of the network? For example, if I wanted to download files using Grokster, it would download incredibly slow ( about 0.3 k/sec). The only program I have come across that is not affected by the network restrictions is mIRC. Are there any other programs out there that will work besides mIRC? Or is there a way I can get around the packet shaping for the network?
 
The packet shaping is in effect, believe it or not, for your own good. P2P saturate campus networks to the point where they become unusable. There are also legal implications for campus networks because of the rampant distribution of software, movies, music, etc.

When I worked as a college network admin, the first people to call when the network was slow (before we prioritized our traffic), were the same P2P users that were making it crap out in the first place.

Do not attempt to circumvent your campus's network policies. You will be caught, and you will lose your access at a minimum. And don't anyone give me the line about paying 30 grand for college and how you should be able to do as you please. It doesnt work that way. All campus networks have ToS's and if there is some kind of packet shaping, prioritizing, etc in place, the ToS is guaranteed to say something about not trying to circumvent.

You (or your parents) are paying to get an education. Whether the education you receive is worth the money is another story, but your tuition does not entitle you to unfettered access to what is usually illegal distributed media. Surf the web, use instant messaging, send email, do research....just don't use P2P (if your campus's ToS forbids it...not all do...transfer? 🙂 ), and dont try to get around the restrictions.
 
Please do your best to get around the packet shaping, because these guys are ROBBING YOU! I'd compain to the highest authority within your university - only they can make the changes you desire. What the heck is wrong with these networks that would limit bandwidth.

IT IS YOUR internet connection. Write letters (not e-mail) to everyone in the IT department and even congress.

Demand satisfaction, only through vocal action can we get these stupid, dumb idiot universities to listen to us!

Step upto the IT department and slap them with a white glove and repeat - "I demand satisfaction"

Ya got that RIGHT! Ive had ENUF of the TOS BS.

Tell me about it. Its re-god-damn-diculous. I mean heck back at my parent's place I can download wares at a pretty good clip, but this damn university network suxors rolally. I'm getting ready to 0wnz this place. I've already complained to the Dean of computer science and the director of Campus network systems.

He'd better fix this crappy network or else. I demand satisfaction.
 
LOL. Thanks for the replies. I think I know when I need to go from here to try and get my isssue resolved (if at all).

I can think of several solutions to your "problem."

1. Utilize the student discount effect. There should be plenty of software and whatnot in the campus stores available at a special student rate, take advantage of this.

2. DSL/Cable/Dialup. Get your own unfettered internet connection and do as your ISP allows you.

3. Get a server co-located somewhere. You can then ssh/remote desktop/vnc into that machine, download everything to that machine and use scp/ftp to get the files off of that machine. Chances are FTP and scp are not limited to the degree most file sharing programs are. This also gives you experience in setting up a server, keeping it secure, and you will understand how expensive bandwidth really is.

4. Get together with the people in your dorm. Work on setting up a "file sharing system" there. Even open network shares would get the job done. Everyone can create an open network share on their machine, store their goodz there and allow people to mooch. Localnet bandwidth is much cheaper than Internet. Plus, one of the things higher education is supposed to be good for (but I never found this to be really true) is that it gives you the chance to experience different cultures and different points of view. Think about the variety of people on your floor in the dorm. There are probably the mix of pop, hip-hop, metal, and maybe even some techno listeners on your floor alone. Granted, most of the people there probably listen to the same music as the rest of the people, but you should be able to find one or two different people with different tastes willing to participate.

5. Write a letter to the big wigs informing them of the problem, a solution to the problem, and the benefits to the school and students if your solution was to be put in place. A fairly professional letter, describing how this lack of p2p ability hurts the education of the students, the budget of the school, and the usability of the network could go a long way. Make sure to mention how the extra bandwidth being used would not affect the budget to a significant degree and could make administration of the network easier. If you find ways to make that true, let the rest of us know 😉 With this solution, you dont look like a greedy little kid, and as a benefit to you and your parents, it would be tough for them to justify kicking you out. 🙂

6. Participate in things not involving a computer, kazaa, and a box of kleenex.


These solutions are all valid and possible. None of them quite gives you the ease and simplicity of kazaa and a big pipe, but they will all solve the problem. #4 would be what I would look into, although the security implications are a concern.

Good luck.
 
depending on what they're using packet shapping or traffic shaping can be very effective and difficult to get around.

Spidey you crack me up.
 
Around here, the entire campus shares 1 T1 line. Most cable modems get more bandwidth down than we do. Without the packet shaper, the file sharing would actually stop normal surfing. Even other students started complaining. Packet shaping can be a good thing if you don't have gobs of bandwidth to divvy out. We give out 128k to the Kazza users to use. At night, they can burst that up to ~512k. Still going to be slow, but when you only have a total of 1.54M, you gotta cut something down.
 
See............at our school, it won't even really let you use Kazzaa, Grokster or Audio Galaxy. You can use them, but it downloads at like 0.3k/sec They must have something to regulates that. Even with packet shaping, those programs should download faster than that. I mean that is a lot slower than dial-up. Any other ideas?

not really, packet shaping can slow any application down to 50 bits/second if configured to do so. Packeteer for instance acutally changes the TCP windows in the TCP header and selectively ACKs receipts and drops packets to force the server and client to readjust windows sizes and speed.

pretty cool stuff really. we use Packeteer packet shapers. awesome product with complete control over bandwidt. I recommend them for the college networks I do.

Darn things are so smart they can recognize application patterns independant of TCP port number and rely on layer7 data analysis.

-edit- So what whats the Dean's response? How about the computing center? Are they going to fix this?
 
Colleges are serious about you not using their bandwidth for illegal file trading.

If you really want, I have a horror story for you involving pre-P2P mp3 distrobtion, a messed up config file, and the FBI.

I suggest using http-tunnel,

It allows you to run programs over the website port of 80, so they think you are just downloading websites. It cost 5 bucks a month to use, but IMO it's well worth it for situtations like you are in.

How is that better than my suggestions? Its not, why? Because getting caught doing things like that can get you in trouble too. 😉
