Tailscale for MustardOS (Andromeda)

Applications Testing
1

MustardOS 2606.0 (Andromeda) removed the bundled Tailscale Web Service. This brings it back, and also keeps it up to date!

Currently, I’ve only tested on my personal RG 34XXSP, and everything seems to work fine.

Install

  1. Download Tailscale.muxapp from the latest release.
  2. Copy it to the ARCHIVE folder on SD1.
  3. Open Applications > Archive Manager and install it.
  4. Open Applications > Tailscale.

Use

The app opens a menu in Mustard Terminal:

Button Action
D-pad Move
Start Select / confirm
B Back / exit
  • Start Tailscale starts the daemon.
  • Log In shows a QR code and login URL. Scan it with your phone and approve the device; press B to cancel.
  • Start on Boot installs MUOS/init/tailscale.sh, which waits up to 2 minutes for Wi-Fi before starting the daemon. This also turns on Advanced > User Init Scripts, because init scripts only run when it is on.
  • Disconnect, Log Out and Stop Tailscale do what they say.

Once the daemon has started, tailscale is linked into /usr/bin, so the normal CLI works over SSH:

tailscale status
tailscale ip -4

Details

  • Node state lives in MUOS/application/Tailscale/state. If you upgraded in place from 2601 and /opt/muos/config/tailscale still exists, it is copied over on first start so the device keeps its identity.
  • The daemon uses the kernel TUN device when available and falls back to userspace networking otherwise. In userspace mode other tailnet devices can still reach this device (SSH, SFTP, Syncthing), but outbound traffic from the device does not route through the tailnet.
  • To use Headscale or another control server, put its URL on the first line of MUOS/application/Tailscale/login_server.
  • Daemon log: /tmp/tailscaled.log.
