history
Project history and usage
cjdns is an encrypted IPv6 mesh-routing system that derives addresses from public keys and uses a distributed hash table for routing. It is packaged as a command-line/network daemon stack centered on `cjdroute`.
Project history
The official repository was created in 2011 and describes cjdns as an encrypted IPv6 network using public-key cryptography for address allocation and a distributed hash table for routing. Its whitepaper frames the project as a clean-slate response to Internet routing, security, decentralization, and ease-of-configuration problems.
The project goals document emphasizes built-in security, auto-configuration, decentralization, and scalability for mesh-like networks.
Adoption history
The batch input records cjdns packages in Homebrew, Alpine, MacPorts, Nix, and Arch/pacman. The upstream README includes Linux and macOS build instructions, an installer-project option, and localized README translations, all signs of a project aimed at technically capable operators across Unix-like systems.
How it is used
Users build or install cjdns, generate `/etc/cjdroute.conf` with `cjdroute --genconf`, protect that file because it contains node identity material, and run the router to join encrypted peer networks.
Why package nerds care
cjdns is package-nerd significant because it is not just a daemon: it packages a whole alternate-networking experiment with crypto identity, TUN/TAP setup, peer configuration, and routing assumptions. It stresses distro policy around networking privileges, service setup, generated secrets, and fast-moving low-level dependencies.
Timeline
- 2011: Official GitHub repository created.
- 2011: Early tags include cjdns-0.1, cjdns-0.2, and cjdns-0.3.
