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 fetching.

       It filters using multiple methods. These methods include URL and domain filtering, content
       phrase  filtering,  PICS  filtering,  MIME  type filtering, 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  undesirable 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)
