Solution For College's Bad Network Policy?
DAMN MY LIFE writes "I'm going to Central Michigan University in the fall. Upon examination of their poorly organized network usage policies, I'm worried that using their internet service will expose my web browsing habits, emails, and most importantly, passwords. Another concern I have is the 'Client Security Agent' that students are required to install and leave on their systems to use the network. Through this application, the IT department scans everyone's computer for what they claim are network security purposes. Of course, scanning a person's hard drive can turn up all kinds of things that are personal. Do all colleges have such extreme measures in place? Is there any way that I can avoid this? There are no wireless broadband providers available in the area, I already checked."
Dude, I don't know what to say, that's insane. The only suggestion I have is to either not use the Internet on your personal computer or find another university to go to. sigh... Looks like along with all the other stuff that determines what school a kid goes to, we're going to have to add "how screwed up is your Internet access policy?" to the list.
Stupid question, what if your machine is a Mac or Linux box? This "Client Security Agent" seems to be a Windows-only beast. Whatever it is, it would be a cold day in hell before I let a university that I'm paying money to dictate that I have to have their software on my machine to use the Internet access that my tuition and fees are paying for!
Looks to me like a clear-cut case of some overzealous IT goob forgotting who is paying whose salary. I'm not saying that you're the Chairman of the Board, but you most certainly should expect to have the right to have full access to this academic resource without this kind of burden.
As a practical matter, you could just call up their IT department and tell them that you have a Linux box, even if you have Windows, and that your machine doesn't run their "Client Security Agent." Whatever they tell you to do to get on the network, just do that on your Windows machine and be done with it. If they tell you that it can't be done, seriously. Go somewhere else. If this university is that stupid, you shouldn't particularly want a diploma from there anyway.
If you do call them up and ask about Macs and Linux machines, let us know what they say.

Look, I'm a fan of net freedom just like you. But let's be honest here. It is the university's network, even if you are semi-footing the bill, and they get to decide network policy rules. It's mostly for prevention, if their students are constantly getting DMCA notices, the university might get into trouble. So of course they block limewire, not like it has a legitimate use anyways. If there's a massive outbreak of viruses on their network, their tech supports (people like me) have to clean up, so of course we force students to have up to date antivirus software, and up to date operating systems, its the method of prevention available.
.exe's, or simple .bat scripts would bypass the network policies.
Simply put, their network, their rules. When you're paying, you can decide the rules you follow, and deal with the consequences if you break some other major rules (laws). If you don't like their rules, complain to them, or go elsewhere. Not like you're forced to stay. Attempting to side-step the rules (especially publicly on slashdot, you know someone in the IT department at your university reads this site) is a very bad plan. Unless if you happen to be a random genius at network security (and if you're asking us, you aren't), you will not outsmart your school's IT department. This isn't high school anymore, where renaming forbidden
Most schools have similar software in place, Tipically, Cisco Clean Access: http://www.google.com/search?q=clean+access+inurl%3Aedu
When I was in the dorms at my school, a guy maintained an InstallVise installer, which contained the proper registry keys to change window's MTU, and
a greasemoney script which spoofed firefox's user agent and platform, so windows machines looked to be running linux.
After seeing someone with a similar solution get kicked out of another school, being published on slashdot, and knowledge that my school's IT dept was searching
for the maintainer, he stopped.
Clean Access now uses a java jar, for the linux platform. If your school's client has something similar in place for linux users, I suggest that you find a Computer Science student,
and ask them to decompile the jar, using the DJ Java Decompiler, and create a greasemoney script that uses a similar method of generating a session key. You'd also probably need
the special registry keys, which can be found in the source code for sec_cloak.c, which you should be able to find on google.
Hope I could help.
My university(Ohio State), tried implementing similar policies last year. They rolled it out to some portion of the student population and said at the forefront that anyone running Mac or Linux was exempt.
As an IT employee at Ohio State, I can assure you that there is more of this in the pipeline since it's mandated by the Board of Trustees.
I can't see comparing what is going on at OSU with what the OP reports at CMU -- Ohio State's efforts to lock down the network and restricted data are quite comprehensive and IT staff, like you, are concerned that it's done properly. Mac/Linux support is on the way -- most vendors do not support it so it's quite difficult for the University to support it. The scanners they run on your computer are not there to look at your personal files, track down copyright infringement, or anything else you might be worried about -- they simply look for OS/software patches and run an anti-virus/malware scan. If you don't run the scan with the agent, you will not have any network access. If you take some of the suggestions here and bypass the security agent, you are violating the AUP and, if caught, could face academic misconduct charges.
I can assure you that the University's IT office is underfunded enough that even if they wanted to go out of their way to scan your computer for anything else (they do not), they would not be able to.
On a related note: Some how, when you connect to the residential network, they can detect some botnet signatures on your machine and will deny you access. Your mac address is blacklisted until you reformat. It runs some utility to make sure you actually have reinstalled before they restore your access.
This isn't magic -- they run typical network vulnerability scanners and block you if a virus or bot responds from your IP. DHCP and switch info tells them your mac address.
