Nmap: Network Exploration and Security Auditing Cookbook - Second Edition

How it works...

The LUA NSE libraries are stored inside the directory /nselib/ in your configured data directory. To create our own libraries, we just need to create the .lua file and place it in that directory:

   --hello.lua    local stdnse = require "stdnse"    _ENV = stdnse.module("mylibrary", stdnse.seeall)    function foo(msg, name)       return stdnse.format("%s %s", msg, name)    end    return _ENV 

NSE scripts can now import your NSE library and call the available functions:

   local hello = require "hello"    ...    hello.foo("Hello", "Martha") 

It is important to document your library well before submitting it to http://insecure.org/ to help other developers quickly understand the purpose and functionality of your new library.
