Tools to Analyze and Visualize Network Packet Capture (PCAP) Files

Description

Life’s too short to export to CSV/XML. There’s no reason R should not be able to read binary PCAP data.

What is a PCAP?

You need the crafter C++ library installed and their site lists the other dependencies.

If there’s any hope for this to run on Windows (libcrafter supports Windows) it will be due to a Windows + (prbly some infosec) + #rstats person tagging along on this project.

You can find some sample PCAP files:

What’s Inside The Tin?

The following functions are implemented:

(The pcap in the functions below is the return value from a call to read_pcap.)

(There are actually more but they’re inside the pcap object and I just need to get them exposed. See the example below for usage.)

Installation

devtools::install_github("hrbrmstr/crafter")

Usage
