Make a dedicated Wake-on-LAN server with Tailscale
Tailscale can do a lot of clever things, but it cannot physically turn on a device that is asleep or powered off—not by itself, anyways. With some help from another system, a little board, or a container, however, we can rouse slumbering devices and bring them back up and onto our Tailnet.
Today, we'll look at how Wake-on-LAN (WoL) and Tailscale can work together, and walk through a couple of useful tools for waking sleeping desktops, servers, and other devices. Wake-on-LAN typically only works on a local network, but working through Tailscale, we can send wake-up signals nearly anywhere the power button is out of reach. We'll dig into:
- Using other devices to wake up your gear, like a Raspberry Pi
- Running a dedicated little wake-up web app you can access from anywhere
- Creating a Tailscale-infused Docker container for that web app
First, let's talk about why Tailscale can’t...
