I also have problems with students browsing the net and not getting work done. 
I thought about changing the rights to mozilla but what about konqueror? They 
need it for a file browser in KDE so they need rights to it. I was wondering 
if there was some kind of command to disable or turn off the NIC that is 
connected to the external network? Physically unplugging the cable seems like 
a kludge especially if the server is in another room.
