This thread is dedicated to installation of CJDNS, an encrypted IPV6 network implementation. It is a part of Project Meshnet which aims to build a secure, decentralized, alternative Internet. I suggest we discuss the philosophy behind Project Meshnet in a separate thread and dedicate this thread for discussing installation and other technical issues.
I recommend regular gnu/linux users to follow the README.md of CJDNS repo for installation. Noobs shall follow this tutorial for automating build and configuration process. I encourage you to write about the installation/setup issues you are facing here.
** Update 01: This article discusses the need for an alternate internet, goals of Project Meshnet and CJDNS : Network Suite for Meshnet
** Update 02: Add Freifunk, GuiFi projects. Compare CJDNS with BATMAN and OLSR.
