[K12OSN] Desktop and Browsing Control

[Bob Hill]

Hello Group,

I am using both K12LTSP 6 and Ubuntu Feisty 7.04 for two small LTSP 
classroom labs.  In both situations, I have installed Sabayon to try to 
create managed profiles for the Gnome desktop.  I would also like to try 
to manage some of the students' web browsing through a whitelist or 
blacklist (I think).  The distros have Squid, SquidGuard, and Dans 
Guardian included.  However, I must admit, I am too much of a Linux noob 
to understand how to get the results I want with these tools.

Question # 1 -- After creating a profile with Sabayon, do I somehow need 
to copy this profile to all user's home or other folders?  The profile 
doesn't always seem to be applied uniformly to the users that I assign 
the profile to.  I think the Sabayon web site says something to this effect.

Question # 2 -- I have tried to get Squid and SquidGuard set up and 
running in each distro, but when I check processes and services, neither 
is listed as running and trying to start / restart them either hangs or 
produces an error message.  Do I need to configure and start Squid, then 
SqidGuard, or Dans Guardian?  Would anyone be willing to share a step by 
step description of how one configures these tools?  The directions I 
have tried to follow from the respective web sites are not working for 
me (sorry for my ignorance).  I think I would like to limit internet 
browsing from the LTSP clients with Firefox to a "whitelist" of sites.  
Are these the tools to do that with, and how?

Thanks for any expertise you are willing to share.
