My crusade for web content filtering

[Kevin Saling]

Wow, I've been away from the PLUG list for a long time.  Good to be back.  I
searched through the archives, but did not find any relevant threads...  so
here goes.

I am trying to create a web content filter at the choke point of my network
that will provide a safe web surfing environment for children downstream (on
the internal LAN).  I can do this directly on the firewall (OpenBSD <shhh>)
or on a separate Linux server (maybe a squid box).  Doesn't matter.

Basically, the hard part has been finding something that provides keyword
searching of incoming html pages.  There are tons of URL filters out there,
but that's _not_ what I'm looking for.  Squid apparently doesn't have an API
that provides access to the actual data stream (just URL's) so a squid
module doesn't seem likely.

So, in the end, my tireless searching (and my friend Stephen <wink>) has
turned up ActiveGuardian and JunkEx as possible options.  Unfortunately,
ActiveGuardian's web forum is not encouraging and JunkEx refuses to install
for me.

Anyone been down this road already?  Care to share your experiences?
