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

David,
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 really don't understand iptables properly. Perhaps its a matter of

Straightforward, no. Or at least not that I know of.
This is one of my major goals for the summer, so I've been reading up
