Brad Fitzpatrick 20a357b386 ipn, ipn/ipnserver: add IPN state for server in use, handle explicitly On Windows, we were previously treating a server used by different users as a fatal error, which meant the second user (upon starting Tailscale, explicitly or via Start Up programs) got an invasive error message dialog. Instead, give it its own IPN state and change the Notify.ErrMessage to be details in that state. Then the Windows GUI can be less aggresive about that happening. Also, * wait to close the IPN connection until the server ownership state changes so the GUI doesn't need to repeatedly reconnect to discover changes. * fix a bug discovered during testing: on system reboot, the ipnserver's serverModeUser was getting cleared while the state transitioned from Unknown to Running. Instead, track 'inServerMode' explicitly and remove the old accessor method which was error prone. * fix a rare bug where the client could start up and set the server mode prefs in its Start call and we wouldn't persist that to the StateStore storage's prefs start key. (Previously it was only via a prefs toggle at runtime)		4 years ago

Tailscale

https://tailscale.com

Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale client code and the tailscaled daemon and tailscale CLI tool. The tailscaled daemon runs primarily on Linux; it also works to varying degrees on FreeBSD, OpenBSD, Darwin, and Windows.

The Android app is at https://github.com/tailscale/tailscale-android

Using

We serve packages for a variety of distros 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 that are not open source.

Building

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.

We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.15) 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.

Contributing

PRs welcome! But please file bugs. Commit messages should reference bugs.

We require Developer Certificate of Origin Signed-off-by lines in commits.
