"squidGuard describes itself as: 'An ultrafast and free filter,
redirector and access controller for Squid.' In my experience, it
is the ideal web filter for use with Smoothwall since it is
lightweight and easy to set up. I use it on an i486, 33Mhz system
with 18Mb of Ram and 500Mb of hard drive--and while there is a
minor performance hit, the hit is not significant.
"This simple how-to describes the steps I took to install
squidGuard on my system--it should work for yours too..."
