[gentoo-user] Office web filtering

[Stroller]

Hi there,

Anyone got any suggestions regarding web filtering for a small office  
of a dozen employees?

I'd assume Squid + Google-it-you-lazy-git, but there are a couple of  
requirements that make my request a little unusual.

Firstly, instead of simply blocking pr0n & allowing everything else,  
the site primarily wants to block Hotmail & Facebook.

I assume that what this _really means_ is that they want to block  
everything by default and add a whitelist of work-related sites (it's  
an estate agent, so http://rightmove.co.uk would be on the whitelist,  
for instance).

Secondly, they want to perform the blocking for most of the day, but  
relax the restrictions between 11am - 11:15am & 1pm - 2pm.

And thirdly, the bosses want to be excluded from the filtering. One  
obvious way to do this is filtering by their MAC or IP address - none  
of the staff are geek enough to get around this but nevertheless it's  
a bit clumsy & requires maintenance if the boss gets a new laptop.

So what I'd prefer is really some kind of system that pops up a  
message "this site cannot be displayed because it is in the filter  
category [pr0n|frivolous]; if you would like to see it anyway, please  
enter your username & password". I used to work at a place that  
displayed a similar message & allowed with a single click a user to  
submit to the admin websites that had been blacklisted in error; so I  
am sure something like this is possible, I just don't know if it's  
available in open-source.

Thanks in advance,

Stroller.
