Add a vmtest that brings up two Ubuntu nodes, each behind its own EasyNAT, joined to the tailnet. The sender pushes a small file via "tailscale file cp" and the receiver fetches it via "tailscale file get --wait", asserting that the filename and contents round-trip unchanged. To make Taildrop work in vmtest, three small pieces were needed: The Linux/FreeBSD cloud-init now starts tailscaled with --statedir as well as --state=mem:, so the daemon has a VarRoot to host Taildrop's incoming-files directory. State itself remains in-memory (so nothing persists across reboots); only the var-root scratch space is on disk. vmtest.New grows a variadic EnvOption parameter and a SameTailnetUser helper. When the option is passed, Start sets AllNodesSameUser=true on the embedded testcontrol.Server. Cross-node Taildrop requires the sender and receiver to share a Tailnet user (or have an explicit PeerCapabilityFileSharingTarget granted between them, which we don't plumb here), so TestTaildrop opts in. Existing tests don't. cmd/tta gains /taildrop-send and /taildrop-recv handlers that wrap "tailscale file cp" and "tailscale file get --wait", plus Env.SendTaildropFile and Env.RecvTaildropFile helpers in vmtest that drive them.

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.
