libviface : C++ bindings for Linux tun/tap and netdevice interface

libviface is a small C++11 library that allows to create (or hook to) and configure network interfaces in Linux based Operating Systems.

#include "viface/viface.hpp"

// Create interface
viface::VIface iface("viface%d");

// Configure interface
iface.setMAC("66:23:2d:28:c6:84");
iface.setIPv4("192.168.20.21");

// Bring-up interface
iface.up();

Then you can send(), receive() or setup a dispath() callback to handle virtual interfaces incoming and outgoing packets. Also, interface statistics (rx/tx packets, bytes, etc) are available to read using readStat() and related functions.

For a complete overview check the reference documentation and examples.

Features

Object Oriented approach to create virtual interfaces.
Can also hook to existing interfaces (real).
Multiple strategies for packet reception and emission.
Interface configuration API (MAC, Ipv4, IPv6, MTU).
Interface statistics reading and clearing.
Easily integrated with libtins.

Dependencies

sudo apt-get install build-essential cmake doxygen graphviz

Build

mkdir build
cd build
cmake ..
make
make doc

Improvements

Improve and fix possible race conditions when up/down is issued (and thus packet buffer based on MTU is resized) and a dispatcher is active or any other IO is active.
