Could you share some details about the embedded SSH server? I'm curious if this would work to add SSH capabilities to devices that run Tailscale but don't include a built-in SSH server. Previously I've used dropbear, so it'd be really nice to be able to drop that requirement!

If you're already running recent-ish Tailscale on them, they're already running an SSH server that's just disabled. Run "tailscale up --ssh" to turn it on.

The code's at https://github.com/tailscale/tailscale/tree/main/ssh/tailssh for all the details. Which details in particular are you curious about?

In the linked Q&A video with Maisem, you spoke about buying books on Linux to make SSH work. Which books, if you don't mind me asking?

Ah it's using crypto/ssh to provide the SSH server, so I think that's all the details I needed! Can't wait to give this a shot.
