= pcaprub

This goal of this project is to provide a consistent interface 
to LBL's libpcap packet capture library. This project was created 
because the currently available ruby-pcap library is poorly designed 
and has been unmaintained since 2000. 

This does not provide packet processing functionality, it simply provides 
the interface for capturing packets, and passing yielding those packets. 

For true packet processing capability look at PCAPFU PCAPLET etc..

Requirements:
  libpcap - http://www.tcpdump.org

== Installation  

  gem install pcaprub  

== Usage

 require 'rubygems'
 require 'pcaprub'
 
 cap = PCAPRUB::Pcap.new

== Current Repository for Gemcutter source

The Git Repo on Github @shadowbq is forked from the Metasploit SVN repo
  git clone git://github.com/shadowbq/pcaprub.git

== Notes on 11.x series and beyond.

The gem is now a module. The module is autoincluded, but this helps with name collisions and additional growth.

Some of the Error handling and basic intensive code is moving out the C base-extension (ext) and into native Ruby.

The file handling in dumper is now attached to the Capture Class and not the Module as an additional singleton.

  capture = PCAPRUB::Pcap.open_live('eth0', SNAPLENGTH, true, 0)
  capture.dump_open('./Example.pcap') 
    { ... }
  capture.dump_close
  
== Timstamps from the PCAP Header 

Timestamps are now available when yeilding packets instead of strings

  capture = PCAPRUB::Pcap.open_live('eth0', SNAPLENGTH, true, 0)
  capture.each_packet do |packet|
    puts Time.at(packet.time)
    puts "micro => #{packet.microsec}"
  end
