.SH NAME
|
||||
dnsjit \- DNS engine based around LuaJIT for capturing, parsing, replaying and statistics gathering
|
||||
.SH SYNOPSIS
|
||||
.SS Run a Lua script
|
||||
.B dnsjit
|
||||
.I file.lua
|
||||
.I ...
|
||||
.SS Shebang-style
|
||||
#!/usr/bin/env dnsjit
|
||||
...
|
||||
.SH DESCRIPTION
|
||||
.B dnsjit
|
||||
is a combination of parts taken from
|
||||
.BR dsc ,
|
||||
.BR dnscap ,
|
||||
.BR 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.
|
||||
.LP
|
||||
One of the core functionality that
|
||||
.B 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.
|
||||
.LP
|
||||
.B NOTE
|
||||
current implementation is
|
||||
.I ALPHA
|
||||
which means functionality are not set and may be changed or removed.
|
||||
.LP
|
||||
.SH MODULE CATEGORIES
|
||||
The following Lua module categories exists:
|
||||
.TP
|
||||
.B dnsjit.core
|
||||
Core modules for handling things like logging, DNS messages and
|
||||
receiver/receive functionality.
|
||||
.TP
|
||||
.B dnsjit.lib
|
||||
Various Lua libraries or C library bindings.
|
||||
.TP
|
||||
.B dnsjit.input
|
||||
Input modules used to read DNS messages in various ways.
|
||||
.TP
|
||||
.B dnsjit.filter
|
||||
Filter modules to process or manipulate DNS messages.
|
||||
.TP
|
||||
.B dnsjit.output
|
||||
Output modules used to display DNS message, export to various formats or
|
||||
replay them against other targets.
|
||||
.LP
|
||||
See each category's man-page for more information.
|
||||
.SH LUA GLOBALS
