NYC Resistor runs a node on Yggdrasil, an end-to-end encrypted IPv6 mesh network. Install one program, add a few peers, and the space's node becomes reachable from anywhere, with no port forwarding, no account and no VPN subscription.

https://github.com/yggdrasil-network/yggdrasil-go/releases

Version 0.5.x is required. 0.4.x speaks a different wire protocol and will never connect to anything.

Debian / Ubuntu / Raspberry Pi OS: do not use apt, because the packaged version is 0.4.7. Download the .deb for your architecture instead:

macOS: use the .pkg installer, macos-arm64 for Apple Silicon or macos-amd64 for Intel. There is no Homebrew formula.

Windows: use the .msi from the same page.

A fresh install has an empty peer list and does nothing.

Config file locations:

Fill in the Peers list. These peers are close to NYC:

Every entry must be quoted. An unquoted peer makes the config unparseable and Yggdrasil refuses to start.

Then restart it:

You want to see "Up" beside at least one peer. If they are all Down, your network is probably blocking those ports. Try the :443 peers above; restrictive Wi-Fi usually allows port 443.

The square brackets are part of the address; IPv6 literals need them.

nycr.ygg is the friendlier name for the same machine, but it lives on Alfis, a blockchain DNS system that ordinary resolvers know nothing about. To use the name, run Alfis locally. The bracketed address always works and needs nothing extra.

Yggdrasil is a public network, not a private one. Once you are on it your machine has a globally routable address and anyone else on the mesh can reach it. Addresses are not secret and the network is scannable.

- Check what your machine is serving: ss -tlnH on Linux, or netstat -an

elsewhere. Anything bound to [::] or * is exposed to the whole mesh. Things on 0.0.0.0 or 127.0.0.1 are not.

- If SSH is one of them, use keys and turn off password authentication before

you connect. Default passwords get found.
