setup cjdns mesh network on rpi
Why it is cool The goal here is to make my PI reachable from everywhere, no matter where is it. It’s not like publishing it to the internet, it’s a private network, currently not connected to any external peers, which helps to reduce the attack surface. Think of it as VPN service without any central servers, nodes just connects to each other, and they can reach each other by discovering routes, so if any node breaks down, it will be just that node, and the rest of the network will find an other way around.
