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.
