NAME

       DansGuardian2 - web content filter

SYNOPSIS

       dansguardian [ -c config-file ] [ -v ] [ -h ] [ -N ] [ -q ] [ -Q ] [ -s ] [ -r ] [ -g ]

SUMMARY

       DansGuardian  is  a web content filtering proxy(1) for Linux, NetBSD, FreeBSD, OpenBSD, and Solaris that uses Squid(2) to do all the fetch-
       ing.

       It filters using multiple methods. These methods include URL and domain filtering, content phrase filtering, PICS filtering, MIME type fil-
       tering, file extension filtering, POST limiting and content (AV) scanning.

       The content phrase filtering will check for pages that contain profanities and phrases often associated with pornography and other undesir-
       able content.  The POST filtering allows you to block or limit web uploads.  The URL and domain filtering is able to handle huge lists  and
       is significantly faster than squidGuard.

       Content	scanning enables downloaded content to be passed through ClamD, KAVD, any local program with machine-parseable console output, and
       any other AV scanner available as an ICAP server.

       The filtering has configurable domain, user and source IP exception lists.  SSL tunneling is  supported;  however,  due	to  the  encrypted
       nature  of  HTTPS  requests, filtering is only supported on destination domain.	The configurable logging produces a log in an easy to read
       format which has the option to only log the text-based pages, thus significantly reducing redundant information such as every  image  on  a
       page.

       DansGuardian is under continuous development and so it is best to visit the web site for the latest information.

	(1) Technically DansGuardian is more of a filtering pass-through than a true proxy - but don't let that worry you!

	(2) DansGuardian should work with any proxy, not just Squid. For example, it is known to work with Oops.

OPTIONS

       -c config-file
	      Use the given config-file.

       -v     gives the version number and build options.

       -h     Output a short summary of available command line options.

       -N     Do not go into the background.

       -q     causes DansGuardian to kill any running copy.

       -Q     kill any running copy AND start a new one with current options.

       -s     shows the parent process PID and exits.

       -r     closes all connections and reloads config files by issuing a HUP, but this does not reset the maxchildren option (amongst others).

       -g     gently restarts by not closing all current connections; only reloads filter group config files. (Issues a USR1)
