Squidguard - Novell LINUX ENTERPRISE SERVER 10 SP2 - INSTALLATION AND ADMINISTRATION Installation Manual

41.7 squidGuard

This section is not intended to explain an extensive configuration of squidGuard, only
to introduce it and give some advice for using it. For more in-depth configuration issues,
refer to the squidGuard Web site at http://www.squidguard.org.
squidGuard is a free (GPL), flexible, and fast filter, redirector, and access controller
plug-in for Squid. It lets you define multiple access rules with different restrictions for
different user groups on a Squid cache. squidGuard uses Squid's standard redirector
interface. squidGuard can do the following:
• Limit the Web access for some users to a list of accepted or well-known Web
servers or URLs.
• Block access to some listed or blacklisted Web servers or URLs for some users.
• Block access to URLs matching a list of regular expressions or words for some
users.
• Redirect blocked URLs to an "intelligent" CGI-based information page.
• Redirect unregistered users to a registration form.
• Redirect banners to an empty GIF.
• Use different access rules based on time of day, day of the week, date, etc.
• Use different rules for different user groups.
squidGuard and Squid cannot be used to:
• Edit, filter, or censor text inside documents.
• Edit, filter, or censor HTML-embedded script languages, such as JavaScript or
VBscript.
Before it can be used, install squidGuard. Provide a minimal configuration file as
/etc/squidguard.conf. Find configuration examples in
.squidguard.org/config/. Experiment later with more complicated configura-
tion settings.
