n2n-utils

Introduction

This is a forked version from the original repos.

A few bash scripts for managing a n2n based VPN.

The original scripts do not support Linux (Ubuntu) well. This one works quite well in Ubuntu 14.04.

Get you own copy of this by doing: git clone git://github.com/bhyde/n2n-utils.git
Get reeady to configure things: cp n2n.config-example n2n.config
Edit n2n.config, setting the variables toward the top.
Start a supernode, and an edge ./n2n-supernode-start ./n2n-join
On each edge node:
- clone the utils,
- install your n2n.config file, and
- start an edge ./n2n-join

n2n.config

a file you create from n2n.config-example
n2n.config-example

sketch for the config file.
n2n-join -- script to join the community

Joining the community leads to a new interface appearing on this machine, e.g. tap0, with a MAC address that is stable looks like 01:00:00:xx:xx:xx where xx:xx:xx is taken from some other MAC address on this machine. The new interface participates in a virtual ethernet implemented by N2N. Your IP adress on that network is as specified in your config file. Only the most minimal routing is established. Behind the interface a process, known as an edge, is running.
n2n-kill-edge

Shuts down the edge process running on your machine.
n2n-manage []

Sends to the UDP port of your edge. Note that if your running both an edge and a super node it's a race who get's this cmd.
n2n-status

Displays various status information about your participation in the community.
n2n-all-traffic

Changes your routing so that the default route for packets is to the gateway mentioned in your config file, presumably an IP address in the VPN. Before setting that it creates a specific rule to the supernode, which means, in due course all the encrypted packets that support the VPN will flow via the supernode.
n2n-no-traffic

Undoes the routing rules setup by n2n-all-traffic.
n2n-supernode-start

Starts up a supernode.
