This goal of this project is to provide a consistent interface to LBL’s libpcap packet capture library.
Limitations
This does not provide packet processing functionality, it simply provides the interface for capturing packets, and passing yielding those packets.
For packet processing capability look at ruby gems PCAPFU, PCAPLET, etc..
Requirements
MRI POSIX Ruby (Native compilation) [Travis-CI Tested]
~> Ruby 2.4
libpcap - http://www.tcpdump.org
Ruby with DevKit(32bit) on Windows [AppVeyor Tested]
Ruby 1.9.3
~> Ruby 2.x
WinPcap Developer's Pack - http://www.winpcap.org
Installation
gem install pcaprub
Advanced options in a Windows ENV
gem install pcaprub --no-ri --no-rdoc -- --with-pcap-dir="c:/dev/src/WpdPack"
Usage
require 'rubygems'
require 'pcaprub'
cap = PCAPRUB::Pcap.new
Current Repository for Gemcutter source
The Git Repo on Github @pcaprub is forked from the Metasploit SVN repo
git clone git://github.com/pcaprub/pcaprub.git
Additionals
Notes on 0.11.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
Ruby 1.8.7 & WinPcap
On Ruby 1.8 with winpcap, rb_thread_polling pauses for 100 milliseconds between reads. This may mean some packets are missed.
