re6stnet
Resilient, Scalable, IPv6 Network application

Overview
re6stnet creates a resilient, scalable, ipv6 network on top of an existing ipv4 network, by creating tunnels on the fly, and then routing targeted traffic through these tunnels.
re6stnet can be used to:
guarantee connectedness between computers connected to the internet, for which there exists a working route (in case the direct route isn’t available).
create large networks
give ipv6 addresses to machines with only ipv4 available
Building an ipv4 network is also supported if one has software that does not support ipv6.
How to pronounce re6st? Like resist.
HOW IT WORKS
A re6stnet network consists of at least one server (re6st-registry) and many nodes (re6stnet). The server is only used to deliver certificates for secure authentication of peers, and to bootstrap new nodes. re6stnet can detect and take into account nodes present on the local network.
Resilience
re6stnet guarantees that if there exists a route between two machines, traffic will be correctly routed between these two machines. Even if the registry node is down, the probability that the network is not connected is very low for big enough networks (more than a hundred nodes).
Scalability
Since nodes don’t need to know the whole graph of the network, re6stnet is easily scalable to tens of thousand of nodes.
Requirements
Python 2.7
OpenSSL binary and development libraries
OpenVPN >= 2.4
Babel (with Nexedi patches)
geoip2: python library and country lite database (optional)
python-miniupnpc for UPnP support (optional)
for the demo: miniupnpd, Graphviz, Screen, Nemu, MultiPing, psutil
See also setup.py for Python dependencies.
Installation
Packages (preferred method)
We are providing a re6st-node package for many distributions. In order to install it, go to
https://build.opensuse.org/package/show/home:VIFIBnexedi/Re6stnet
and find your distribution on the build result at the right of the page. Once you have your distribution name <DISTRIB_NAME>, the repository to add is
http://download.opensuse.org/repositories/home:/VIFIBnexedi/<DISTRIB_NAME>
For example (as root):
Ubuntu 16.04:
echo "deb http://download.opensuse.org/repositories/home:/VIFIBnexedi/xUbuntu_16.04 ./" >/etc/apt/sources.list.d/re6stnet.list wget -qO - https://download.opensuse.org/repositories/home:/VIFIBnexedi/xUbuntu_16.04/Release.key |apt-key add -
Debian 9:
echo "deb http://download.opensuse.org/repositories/home:/VIFIBnexedi/Debian_9.0 ./" >/etc/apt/sources.list.d/re6stnet.list wget -qO - https://download.opensuse.org/repositories/home:/VIFIBnexedi/Debian_9.0/Release.key |apt-key add -
Then:
apt update apt install re6st-node
Python egg
