Registration server

Building the registration server: Need packages:

sudo apt install libzmq3-dev libzmq5 make build-essential

Tested with go1.20.5

cd cmd/registration-server
make

Installing bin files

cp -r conjure /opt/
mkdir /opt/conjure/bin
cp /opt/conjure/cmd/registration-server/registration-server /opt/conjure/bin/

Config files in /var/lib/conjure

mkdir /var/lib/conjure/
cp conjure/sysconfig/conjure.conf /var/lib/conjure/conjure.conf
cp conjure/cmd/registration-server/reg_config.toml /var/lib/conjure/reg_config.toml

Edit reg_config.toml to add pubkeys for stations, and update bidirectional_api_generation to current generation.

Write phantom_subnets.toml, e.g.:

    [Networks.1119]
        Generation = 1119
        [[Networks.1119.WeightedSubnets]]
            Weight = 9
            Subnets = ["192.122.190.0/24", "2001:48a8:687f:1::/64"] 
        [[Networks.1119.WeightedSubnets]]
            Weight = 1
            Subnets = ["141.219.0.0/16", "35.8.0.0/16"] 

Put the most recent ClientConf in /var/lib/conjure/

Make private keys: privkey comes from the stations, zmq_privkey is per-registration server

cd conjure/libtapdance
make
sudo cp privkey /var/lib/conjure/zmq_privkey

Extract the public key: tail -c32 zmq_privkey | basenc --z85

Install this into the app_config.toml of all the stations, e.g.:

[[connect_sockets]]
address = "tcp://reg3.refraction.network:5591"
type = "CURVE"
pubkey = "ZmZ7vr]i&g+.F$JfL5beQZI*kO)rwj9b?*!7woS]"
subscription = ""

Setup Caddy:

registration.refraction.network {
    route /api/* {
        uri strip_prefix /api
        reverse_proxy localhost:8080 {
            trusted_proxies 0.0.0.0/0
        }
    }
}

sudo systemctl reload caddy

DNS registrar

To make the DNS registrar work, we need to listen on :53. Ubuntu normally has resolvd listening there, so we can disable it:

sudo systemctl disable systemd-resolved.service
sudo systemctl stop systemd-resolved.service
echo "nameserver 8.8.8.8" > /etc/resolv.conf

Running

sudo systemctl start conjure-reg
