Diet256

Diet256 is a centrally coordinated, densely connected overlay network, implementing the INET256 spec. It's the same simple INET256 API, but without any of peering or routing configuration to manage.

Diet256 makes all its connections over The Internet using QUIC and uses a central server to discover the IP address of peers. The central server is outside an INET256 application's security perimeter, and the worst thing it can do is misinform a client about the location of a peer. It can't trick applications into sending or receiving messages to or from the wrong peers.

Getting Started

Either download a binary from the release page or build from source.

Installing From Source

In the repo, run make install and it will install to $GOPATH/bin.

Run the Daemon

You can run diet256 as a fully functional INET256 implementation (instead of the reference implementation).

$ diet256 daemon

All the INET256 tools will work with diet256 including the IPv6 Portal.

Using this Library

You can import this package as a go library and build an INET256 application without running any additional daemon processes.

package main

import (
	"context"
	"crypto/ed25519"
	"log"

	"github.com/inet256/diet256"
	"github.com/inet256/inet256/pkg/inet256"
)

func main() {
	srv, err := diet256.New() // That's it; now you're ready to create Nodes.
	if err != nil {
		log.Fatal(err)
	}

	// Provide a key, which will determine the Node's local address
	_, privateKey, _ = ed25519.GenerateKey(nil)
	node, err := srv.Open(ctx, privateKey)
	if err != nil {
		log.Fatal(err)
	}
	defer node.Close()
	log.Println("local node:", node.LocalAddr())

	// dst is the address of the peer you want to send to.
	dst := inet256.ID{}
	node.Send(context.Background(), dst, []byte("ping"))
}

Run the IPv6 Portal In-Process

Normally, the IPv6 Portal runs as its own process, separate from the INET256 daemon. You can do that with inet256 ip6-portal, if diet256 daemon or another INET256 implementation is running.

diet256 also supports an in process IPv6 portal. You can launch that with

$ diet256 ip6-portal --private-key ./path/to/private_key.pem

INFO[0000] opened node jAeAUgztUHiKUgNpIDtzBcVm19Y9Y829MvhqFvG3VSY
INFO[0000] Created TUN utun2
INFO[0000] Local INET256: jAeAUgztUHiKUgNpIDtzBcVm19Y9Y829MvhqFvG3VSY
INFO[0000] Local IPv6: 200:603c:290:676a:83c4:5290:1b49:1db

And then you will have a TUN device connected to the diet256 network using the standard IPv6-to-INET256 address mapping.
