NAME

       dnsjit  -  DNS engine based around LuaJIT for capturing, parsing, replaying and statistics
       gathering

SYNOPSIS

   Run a Lua script
       dnsjit file.lua ...

   Shebang-style
         #!/usr/bin/env dnsjit
         ...

DESCRIPTION

       dnsjit is a combination of parts taken from dsc, dnscap, drool, and  put  together  around
       Lua  to  create a script-based engine for easy capturing, parsing and statistics gathering
       of DNS message while also providing facilities for replaying DNS traffic.

       One of the core functionality that dnsjit brings is to tie  together  C  and  Lua  modules
       through   a  receiver/receive  interface.   This  allows  creation  of  custom  chains  of
       functionality to meet various requirements.  Another core functionality is the ability  to
       parse  and  process  DNS  messages  even  if  the  messages are non-compliant with the DNS
       standards.

       NOTE current implementation is ALPHA which means functionality are  not  set  and  may  be
       changed or removed.

MODULE CATEGORIES

       The following Lua module categories exists:

       dnsjit.core
              Core  modules  for  handling things like logging, DNS messages and receiver/receive
              functionality.

       dnsjit.lib
              Various Lua libraries or C library bindings.

       dnsjit.input
              Input modules used to read DNS messages in various ways.

       dnsjit.filter
              Filter modules to process or manipulate DNS messages.

       dnsjit.output
              Output modules used to display DNS message, export to  various  formats  or  replay
              them against other targets.

       See each category's man-page for more information.

LUA GLOBALS

       The following Lua global variables are defined:

       DNSJIT_VERSION
              A string with the full version.

       DNSJIT_MAJOR_VERSION
              An integer with the major version number.

       DNSJIT_MINOR_VERSION
              An integer with the minor version number.

       DNSJIT_PATCH_VERSION
              An integer with the patch version number.

       DNSJIT_BUGREPORT
              A string with the email address to file bug reports to.

       DNSJIT_URL
              A  string with the URL to the repository issue tracker, preferred place to file bug
              reports.

EXAMPLE

       Following example display the DNS ID found in queries.

         local input = require("dnsjit.input.pcapthread").new()
         local output = require("dnsjit.filter.lua").new()

         output:func(function(filter, object)
             local packet = object:cast()
             local dns = require("dnsjit.core.object.dns").new(packet)
             dns:parse()
             print(dns.id)
         end)

         input:open_offline("file.pcap")
         input:only_queries(true)
         input:receiver(output)
         input:run()

       See more examples in the examples directory.
