Yggdrasil
Introduction
Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging, supported on multiple platforms and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes. Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4.
Although Yggdrasil shares many similarities with cjdns, it employs a different routing algorithm based on a globally-agreed spanning tree and greedy routing in a metric space, and aims to implement some novel local backpressure routing techniques. In theory, Yggdrasil should scale well on networks with internet-like topologies.
Supported Platforms
We actively support the following platforms, and packages are available for some of the below:
- Linux
.deb
and.rpm
packages are built by CI for Debian and Red Hat-based distributions- Void and Arch packages also available within their respective repositories
- macOS
.pkg
packages are built by CI
- Ubiquiti EdgeOS
.deb
Vyatta packages are built by CI
- Windows
- FreeBSD
- OpenBSD
- NetBSD
Please see our Platforms pages for more specific information about each of our supported platforms, including installation steps and caveats.
Building
If you want to build from source, as opposed to installing one of the pre-built packages:
- Install Go (requires Go 1.11 or later)
- Clone this repository
- Run
./build
Note that you can cross-compile for other platforms and architectures by
specifying the GOOS
and GOARCH
environment variables, e.g. GOOS=windows ./build
or GOOS=linux GOARCH=mipsle ./build
.
Running
Generate configuration
To generate static configuration, either generate a HJSON file (human-friendly, complete with comments):
./yggdrasil -genconf > /path/to/yggdrasil.conf
... or generate a plain JSON file (which is easy to manipulate programmatically):
./yggdrasil -genconf -json > /path/to/yggdrasil.conf
You will need to edit the yggdrasil.conf
file to add or remove peers, modify
other configuration such as listen addresses or multicast addresses, etc.
Run Yggdrasil
To run with the generated static configuration:
./yggdrasil -useconffile /path/to/yggdrasil.conf
To run in auto-configuration mode (which will use sane defaults and random keys at each startup, instead of using a static configuration file):
./yggdrasil -autoconf
You will likely need to run Yggdrasil as a privileged user or under sudo
,
unless you have permission to create TUN/TAP adapters. On Linux this can be done
by giving the Yggdrasil binary the CAP_NET_ADMIN
capability.
