Add tstest/natlab/vmtest, a high-level framework for running multi-VM
integration tests with mixed OS types (gokrazy + Ubuntu/Debian cloud
images) connected via natlab's vnet virtual network.
The vmtest package provides:
- Env type that orchestrates vnet, QEMU processes, and agent connections
- OS image support (Gokrazy, Ubuntu2404, Debian12) with download/cache
- QEMU launch per OS type (microvm for gokrazy, q35+KVM for cloud)
- Cloud-init seed ISO generation with network-config for multi-NIC
- Cross-compilation of test binaries for cloud VMs
- Debug SSH NIC on cloud VMs for interactive debugging
- Test helpers: ApproveRoutes, HTTPGet, TailscalePing, DumpStatus,
WaitForPeerRoute, SSHExec
TTA enhancements (cmd/tta):
- Parameterize /up (accept-routes, advertise-routes, snat-subnet-routes)
- Add /set, /start-webserver, /http-get endpoints
- /http-get uses local.Client.UserDial for Tailscale-routed requests
- Fix /ping for non-gokrazy systems
TestSubnetRouter exercises a 3-VM subnet router scenario:
client (gokrazy) → subnet-router (Ubuntu, dual-NIC) → backend (gokrazy)
Verifies HTTP access to the backend webserver through the Tailscale
subnet route. Passes in ~30 seconds.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
