I need to set up a Linux workstation (Computers for Families project) 
that filters content.  The workstation is an edubuntu install.  Users 
have a generic login, separate from the admin, and the root account is 
locked.  I added Squid and DansGuardian, which works perfectly once the 
Firefox connection settings are set to 127.0.0.1:8080.  Problem is that 
any user can override this setting in their local profile.

Is there an elegan way to prevent a user from changing this setting and 
surfing the sites of ill repute?

Kluge/Hackjob method 1:
I guess I could implement a cronjob that checks to see if firefox has 
any established port 80 connections, then kills it.  Pretty Draconian, 
but it will get the point across.  Make pref.js read-only for the user 
which restores the proxy settings.  Pretty inconvenient for the user :(


Thoughts?
