RE: [gentoo-user] Office web filtering

Hi Stroller,

I have found www.opendns.com to be a really good solution. However, it
will be blanket cover for the whole lan and you won't be able to
implement the time-based, or the user-based exceptions.

Kind regards

Subject: [gentoo-user] Office web filtering

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.
