audispd - an event multiplexor




   audispd  is  an  audit  event  multiplexor. It has to be started by the
   audit daemon in  order  to  get  events.  It  takes  audit  events  and
   distributes  them  to  child  programs  that  want to analyze events in
   realtime. When the audit daemon receives a SIGTERM or SIGHUP, it passes
   that signal to the dispatcher, too. The dispatcher in turn passes those
   signals to its child processes.

   The child programs install a configuration file in a plugins directory,
   /etc/audisp/plugins.d.  Filenames are not allowed to have more than one
   '.' in the name or it will be treated as a  backup  copy  and  skipped.
   Options  are  given one per line with an equal sign between the keyword
   and its value. The available options are as follows:

   active The options for this are yes or no.

          The option is dictated by the plugin.  In or out  are  the  only
          choices.  You  cannot  make  a plugin operate in a way it wasn't
          designed just by changing this option.This option is to  give  a
          clue  to the event dispatcher about which direction events flow.
          NOTE: inbound events are not supported yet.

   path   This is the absolute path to the plugin executable. In the  case
          of internal plugins, it would be the name of the plugin.

   type   This  tells  the  dispatcher  how  the  plugin  wants to be run.
          Choices are builtin and always.  Builtin should always be  given
          for  plugins  that  are  internal to the audit event dispatcher.
          These are af_unix and syslog. The option always should be  given
          for most if not all plugins. The default setting is always.

   args   This  allows  you  to  pass  arguments  to  the  child  program.
          Generally plugins do not  take  arguments  and  have  their  own
          config  file  that instructs them how they should be configured.
          At the moment, there is a limit of 2 args.

   format The valid options for this are binary and string.  Binary passes
          the  data exactly as the audit event dispatcher gets it from the
          audit  daemon.  The  string  option  tells  the  dispatcher   to
          completely  change  the event into a string suitable for parsing
          with the audit parsing library. The default value is string.
