If you don't succeed in 3 weeks, perhaps you could change permissions on
the browser and only allow members of a certain group execute it.
That will give you longer to find a better solution.
If you are controlling a whole class of pupils, just put a comment in
/etc/resolv.conf and deny access

I am in the process of setting up a computer lab with Ubuntu 12.04, LTSP, and
a number of thin clients. All is well, except that I cannot figure out how to
deny internet access to particular users while allowing internet access to
others.
Heureka, I resolved the problem. My own question eventually led me
there, (and reading the f*ing manual helped, as usually ;-) ). I would
not have managed if I hadn't asked the question at this list. Thanks!

I'm doing this with iptables for quite some years now, but it includes
an application for the teacher to set/release the lock for a class as
well as some scripts to call iptables etc. And the application has to know
- which user is in the class
- which terminal the user is logged in
Thank you, Rolf. I have tried a few settings with iptables, but I must be
doing something wrong because it has the effect of blocking the desktop
environment from being set up on the client after login. I'm sure it's because

I set up my prototype computer lab based on Ubuntu 12.04, and it's working
fine, but I prefer the KDE desktop. I'd appreciate hearing from anyone who has

Nepomuk and plasma-desktop are driving me crazy on my home machine.
They randomly steal 100% of one of my CPUs and make my fan work
overtime. As a result, I've switched to Xfce. There's a bit of a
