Rtins: Tools for Sniffing, Reading, and Parsing Network Packet Capture (PCAP) Files in R

The Rtins package provides tools for analysing network captures in R on top of libtins, a high-level, multiplatform C++ network packet decoding and crafting library.

Installation

This fork of Rtins requires the data.table R package for accelerated handling of large data sets. (https://cran.r-project.org/web/packages/data.table/index.html) You need to install the libtins library first. And as a minimum requirement, libtins needs the development package of libpcap (or WinPcap for Windows). On Linux,

# install libpcap-devel, openssl-devel is also recommended
git clone https://github.com/mfontanini/libtins.git
mkdir libtins/build
cd libtins/build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make
sudo make install

Please, refer to the libtins documentation for the installation in other platforms. Then, Rtins can be installed using devtools:

devtools::install_github("jimeharrisjr/Rtins")

Usage

library(Rtins)

fname <- system.file("pcaps/http.cap", package="Rtins")
pcap <- read_pcap(fname)
head(pcap)
