Alex Chan 5a6f20432c ipn, cmd/tailscale/cli: allow setting FQDN sans dot as an exit node
In #10057, @seigel pointed out an inconsistency in the help text for
`exit-node list` and `set --exit-node`:

1.  Use `tailscale exit-node list`, which has a column titled "hostname"
    and tells you that you can use a hostname with `set --exit-node`:

    ```console
    $ tailscale exit-node list
     IP                  HOSTNAME                               COUNTRY            CITY                   STATUS
     100.98.193.6        linode-vps.tailfa84dd.ts.net           -                  -                      -
    […]
     100.93.242.75       ua-iev-wg-001.mullvad.ts.net           Ukraine            Kyiv                   -

    # To view the complete list of exit nodes for a country, use `tailscale exit-node list --filter=` followed by the country name.
    # To use an exit node, use `tailscale set --exit-node=` followed by the hostname or IP.
    # To have Tailscale suggest an exit node, use `tailscale exit-node suggest`.
    ```

    (This is the same format hostnames are presented in the admin
    console.)

2.  Try copy/pasting a hostname into `set --exit-node`:

    ```console
    $ tailscale set --exit-node=linode-vps.tailfa84dd.ts.net
    invalid value "linode-vps.tailfa84dd.ts.net" for --exit-node; must be IP or unique node name
    ```

3.  Note that the command allows some hostnames, if they're from nodes
    in a different tailnet:

    ```console
    $ tailscale set --exit-node= ua-iev-wg-001.mullvad.ts.net
    $ echo $?
    0
    ```

This patch addresses the inconsistency in two ways:

1.  Allow using `tailscale set --exit-node=` with an FQDN that's missing
    the trailing dot, matching the formatting used in `exit-node list`
    and the admin console.

2.  Make the description of valid exit nodes consistent across commands
    ("hostname or IP").

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:

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 1.25. (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.
