Tailscale can run on Arch Linux (64-bit x86 only). See archlinux.org for more info.

1. Install Tailscale on Arch Linux:

   pacman -S tailscale
   

2. Use systemctl to enable and start the service:

   sudo systemctl enable --now tailscaled
   

3. Connect your machine to your Tailscale network and authenticate in your browser:

   sudo tailscale up
   

4. You’re connected! You can find your Tailscale IPv4 address by running:

   tailscale ip -4
   

If the device you added is a server or remotely-accessed device, you may want to consider disabling key expiry to prevent the need to periodically re-authenticate.
