[Cjdns](https://github.com/cjdelisle/cjdns) implements an encrypted IPv6 network using public-key cryptography for address allocation and a distributed hash table for routing. This provides near-zero-configuration networking, and prevents many of the security and scalability issues that plague existing networks. ## Contents * [1 Installation](#Installation) * [2 Configuration](#Configuration) * [3 Starting](#Starting) * [4 See also](#See_also) ## Installation [Install](/index.php/Install "Install") [cjdns](https://www.archlinux.org/packages/?name=cjdns). An alternative [cjdns-git](https://aur.archlinux.org/packages/cjdns-git/) package (with more dependencies) is also available. Both packages include a systemd service file, but sysvinit scripts are available too as [cjdns-git-sysvinit](https://aur.archlinux.org/packages/cjdns-git-sysvinit/). ## Configuration On installation, a `/etc/cjdroute.conf` is autogenerated. If you need to re-generate it, execute: ``` # cjdroute --genconf > /etc/cjdroute.conf ``` **Note:** Double-check [file permissions](/index.php/File_permissions_and_attributes#Changing_permissions "File permissions and attributes") for `/etc/cjdroute.conf` as it contains the private key capable of encrypting and decrypting all your communications. Executing `chmod 600 /etc/cjdroute.conf` as root sets them correctly. Edit `/etc/cjdroute.conf` as root to add at least one peer to the `connectTo` section. Peers can be anyone else running cjdns who gives you credentials to connect to them with. They can be found in [Hyperboria peers](https://github.com/hyperboria/peers), #cjdns and #projectmeshnet on [EFnet](http://www.efnet.org) among many other places. ## Starting [Start/enable](/index.php/Start/enable "Start/enable") the `cjdns.service`. If *cjdns* did not start, you should check for errors and edit `/etc/cjdroute.conf` if needed: ``` # systemctl status cjdns # journalctl -u cjdns ``` ## See also * [Wikipedia:Cjdns](https://en.wikipedia.org/wiki/Cjdns "wikipedia:Cjdns")
