Add a new Prefs.RemoteConfig bool. When true, a c2n endpoint at
/remoteapi/localapi/* proxies into this node's LocalAPI at
/localapi/* with full read/write permission, giving the tailnet
admin the same API surface a local root/admin user has via the
tailscale CLI. All LocalAPI versions (v0, v1, ...) proxy through.
RemoteConfig is an alternative to Tailscale's default per-feature
double opt-in, in which both the tailnet admin and the local machine
owner must consent to each individual setting change. It is a single
client-side "I trust the tailnet admin" switch that, once on, hands
over full remote management of this node's settings and LocalAPI
without any further local prompt or confirmation.
This is only appropriate when the tailnet admin already owns the
machine (e.g. a corporate fleet device) or the local user has
explicitly delegated full control. It should never be enabled on a
personal/BYOD device with an untrusted tailnet admin. The trust
model is documented on the pref, on the hidden --remote-config CLI
flag, and on the feature/remoteconfig package.
The node advertises its RemoteConfig state to the control plane via
a new Hostinfo.RemoteConfig bool. This is only true when the feature
is both compiled in (buildfeatures.HasRemoteConfig) and its init
actually ran (feature.IsRegistered("remoteconfig")); tsnet builds
have the former but not the latter and correctly report false.
The handler lives in feature/remoteconfig and can be omitted with the
ts_omit_remoteconfig build tag. tsnet's TestDeps guards against
accidentally pulling it in.

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.
