Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale code. It currently includes the Linux client.

The Linux client is currently cmd/relaynode, but will soon be replaced by cmd/tailscaled.

Building

go install tailscale.com/cmd/tailscale{,d}

We only support the latest Go release and any Go beta or release candidate builds (currently Go 1.13.x or Go 1.14) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.
