cjdns
Networking Reinvented
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.
Startup
The key part of cjdns is the cjdroute background daemon. To start cjdroute:
systemctl start cjdns
This will generate /etc/cjdroute.conf
pre-populated with random keys and
passwords. At first startup, cjdroute looks for neighboring cjdns peers
on all active network interfaces using a layer 2 (e.g. ethernet) protocol.
This is exactly what you want if you are on a wifi mesh. If you only have a
conventional "clearnet" ISP, see the upstream README for
instructions on adding peers using the UDP protocol. (Search for "Find a
friend".)
After adding peers to /etc/cjdroute.conf
, restart cjdroute with:
systemctl restart cjdns
To have cjdroute start whenever you boot, use
systemctl enable cjdns
If you are on a laptop and suspend or hibernate it, cjdroute will take a few minutes to make coffee and figure out what just happened when it wakes up. You can speed this up dramatically with:
systemctl enable cjdns-resume
The resume service restarts cjdns when the system wakes up from sleep.
