[K12OSN] Denying INet access

[ahodson at elp.rr.com]

Hi Team

Access to Internet resources is, depending on the supervisory skills of
the teacher, an issue that concerns most campus administrators and
staff. For the five K12LTSP labs I help administer, I have developed a
procedure that addresses access:

Blocking Internet
==================

a) Create group noblock
  (#/user/bin/system-config-users)
b) add users to noblock: accounts with access + root
c) goto /usr/bin/... and change group=noblock and permission=750 to:
  amaya, epiphany, konqueror, mozilla and firefox - other browsers
  like opera, w3m if installed also need change
d) prepare to answer "Why am I getting an error?" questions

There may be easier ways of doing this - this works for me and wanted to
share it.
