Brad Fitzpatrick 91c9c33036 cmd/tailscaled: don't block ipnserver startup behind engine init on Windows With this change, the ipnserver's safesocket.Listen (the localhost tcp.Listen) happens right away, before any synchronous TUN/DNS/Engine/etc setup work, which might be slow, especially on early boot on Windows. Because the safesocket.Listen starts up early, that means localhost TCP dials (the safesocket.Connect from the GUI) complete successfully and thus the GUI avoids the MessageBox error. (I verified that pacifies it, even without a Listener.Accept; I'd feared that Windows localhost was maybe special and avoided the normal listener backlog). Once the GUI can then connect immediately without errors, the various timeouts then matter less, because the backend is no longer trying to race against the GUI's timeout. So keep retrying on errors for a minute, or 10 minutes if the system just booted in the past 10 minutes. This should fix the problem with Windows 10 desktops auto-logging in and starting the Tailscale frontend which was then showing a MessageBox error about failing to connect to tailscaled, which was slow coming up because the Windows networking stack wasn't up yet. Fingers crossed. Fixes #1313 (previously #1187, etc) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		3 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 1.16) 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.

Tailscale is primarily developed by the people at https://github.com/orgs/tailscale/people. For other contributors, see:
