Machine

Processors Memory Graphics

Kept in this browser. A suspended machine resumes with the size it had; Boot instead starts it from its disk with this one.

Network

Log in… Internet through

This machine's tailcat address

On another computer: tailcat ssh <address> logs in to the guest's sshd, tailcat <address> <port> reaches any port it listens on. Anyone with the address gets in.

Network

How should this machine reach a network? Its network card is always there: connecting doesn't restart it.

Control server Hostname Auth key (optional, never saved) Show the auth key

Without an auth key you log in, in a new tab, and the machine stays on the tailnet over reloads. With one there's no login, the key isn't kept and the node is ephemeral. A Headscale must answer /key with CORS headers.

Go online through a computer of mine

Its tailcat address (never saved)

On that computer run tailcat serve exit-node (tailcat) and paste the address it prints: the machine reaches what that computer reaches, its LAN and the internet. Keep the address to yourself: it lets anyone in.

Let tailcat clients in to this machine

The machine gets a tailcat address of its own, kept in this browser. With it another computer runs tailcat ssh <address> to log in to the guest's sshd, or tailcat <address> <port> for any port the guest listens on.

Advanced

Relay for clients

Your own derper's host or host:port: faster than tailcat's public relays, which are rate-limited. Used when the machine doesn't go online through a computer of yours (that computer's relay serves then).

Forgets the machine's address: whoever has it can't come in any more.

Screen

Size HiDPI

A text console (fbcon) keeps the size it started with: a new size takes effect at the next boot (Restart), and the console is centred until then. A desktop takes it when it starts; whether it follows a change is up to its compositor (sway doesn't).

Sound

Sound on Volume Microphone Raw microphone

Kept in this browser. The browser plays sound once the page has had a click or a key.

Keys

Ctrl+Alt+

Save disk

Compress the qcow2

The machine stops while the file is written, as if its plug were pulled: shut it down first (poweroff) for a clean disk.

Click to type

The boot menus, and a first boot's questions, are on the serial console.
