Basics
DansGuardian is an award winning Open Source web content filter which currently runs on Linux, FreeBSD, OpenBSD, NetBSD, Mac OS X, HP-UX, and Solaris. It filters the actual content of pages based on many methods including phrase matching, PICS filtering and URL filtering. It does not purely filter based on a banned list of sites like lesser totally commercial filters.
DansGuardian is designed to be completely flexible and allows you to tailor the filtering to your exact needs. It can be as draconian or as unobstructive as you want. The default settings are geared towards what a primary school might want but DansGuardian puts you in control of what you want to block.
DansGuardian is a true web content filter.

Troubleshooting
Adding BlackList
A BlackList is a precompiled list of sites that are deemed potentially worrisome. This list can be obtained for http://www.URLBlacklist.com Here is a step by step guide to adding the biglist to your dansguardian filtering directories
cd /etc/dansguardian
wget http://urlblacklist.com/downloads/OriginalUpdateBL
vi OriginalUpdateBL
- modify line 68 by switching the listed URL with the following:
http://urlblacklist.com/cgi-bin/commercialdownload.pl?type=download&file=bigblacklist
chmod 777 /etc/dansguardian/OrginialUpdateBL /etc/dansguardian/OrginialUpdateBL
when script is finished if you see any errors.
/etc/init.d/dansguardian restart
Fine Tuning the Filtering
Add Sites which are Exempt
vi /etc/dansguardian/exceptionsitelist
- this will speed up these sites
Customize the types of sites you want to block
vi /etc/dansguardian/bannedsites
- scroll to the bottom of the page and uncommit out the lines of the types of site you would like to filter out
- Restart dansguardian
/etc/init.d/dansguardian restart
