I’d say,t hey’re within their rights to ask him to stop using TOR. As always, the “policy” should be refined – but they can in fact say what their network will and will not be used for, and how it is used.

Asking him to not teach it, however, is a very different matter and I’m glad he took the stance he did.

They can’t prove that he’s doing anything wrong with it, though. The presence of privacy-enabling software does not necessarily mean that one is doing anything illegal. I agree that the policy in question should be refined, though – it is, if memory serves, over a decade out of date, and thus out of step with technology. I sincerely hope that the professor in question continues to make it possible for users of that campus’ network to maintain a sense of security and confidentiality.

Point being, they’re in no wise obligated to allow privacy. Wrongdoing or no, it’s not his network; they can disallow whatever they damn well please*. It’s a common misapprehension that the limitations placed ont he government are the limitatinos placed on all institutions; this is not the case.

*within various strictures of law, etc.

If it’s in the ToS for the school’s network, then no, they aren’t. If there isn’t, then I’m not so sure. I think there’s a legal expectation of privacy inherent there, modulo signs of wrongdoing (which there appears to be on someone’s part).

I’d have to argue against that. De facto assumption of privacy or not, there’s an explicit ownership involved. This isn’t even a service being offered tot he paying public: this is a campus LAN. THey could decide to block port 80 on prime-numbered days… at most they’d simply have to employ the “can change without notice” clause in the TOS.

That said, trying to intimidate a tenured professor is really dumb – in an academic environment that’s like getting into a water-gun fight with a dragon. They should have simply disallowed at the router. Being unable to read it doesn’t mean unable to block it. But they’re obviously not router-types, or they’d have been able to trace back to the exact port of the alleged violator.

You have a point there. It’s also pretty standard in the ToS agreements of school networks that they can and will monitor traffic and there’s nothing that you can really do to change that. When I was in undergrad, they kept a close watch on the LAN of my particular floor, and they were known to make good use of the remote management functions of the 10baseT switches they had in the wiring closet.

They could also test out some IPS (intrusion prevention system) functionality, if they’ve been toying with such a thing.

They knew that there was encrypted traffic coming from two points, but they didn’t know which was related to the fraud case they were investigating. On the other hand, they had the real-world IP addresses, so if it’s not the prof up to something, logically one would go to the student… I can understand not cutting a professor a break just because he’s a professor, but what of the other Tor user?

Actually, in general I’ve been given to believe that what a professor wants, a professor gets. Some of them can be total prima donnas. At least,t hat’s how my uni was.

I’d imagine they were trying to find the other TOR user. It might have been someone takign a laptop to the library or the like.

I’ve not seen that first-hand before (mostly because I rarely saw my actual professors) but I’ve heard enough about it that I don’t doubt that it happens.

It might not even have been a student. It’s trivially easy (though difficult to do stealthily) to walk onto campus, crack an access point, and do your thing. It’s also reasonably easy to unplug a public terminal and connect your own laptop to the campus network. Not many campuses have MAC/port locking implemented on their networks at this time.

How can i make TOR use a new exit-node for each web-page i visit? http://toatechestiile.ro

Popescu (URL) - 29 07 07 - 08:22 - Reply to comment?

The easiest way is to use a control application like Vidalia (http://www.vidalia-project.net/). There is a command on the control panel called “Use a new identity” that lets you change your current exit node. Or, you can do nothing for ten minutes and the Tor paths will be torn down and replaced automatically.

In case you’re curious, what gets sent over the command channel (port 9051/TCP) is the string “SIGNAL NEWNYM”, but you have to authenticate yourself to the Tor daemon first.

You can find plenty imformation about tor but i would suggest you won’t use it for traffic or facking adsense.
