test-machine

Scripts for setting up Steinwurf test machines. Each script installs everything a fresh machine needs so it can be reached and used for testing:

• OpenSSH server
• Tailscale, with Tailscale SSH enabled, so the machine is reachable from the tailnet
• Nix and devbox for reproducible dev environments

Ubuntu

On a fresh Ubuntu machine, log in as your normal user and run:

wget -qO- https://raw.githubusercontent.com/steinwurf/test-machine/main/install-ubuntu.sh | sudo bash

wget is preinstalled on Ubuntu; curl usually is not. If you do have curl:

curl -fsSL https://raw.githubusercontent.com/steinwurf/test-machine/main/install-ubuntu.sh | sudo bash

The script runs as root but sets up devbox for the user who invoked sudo. It installs curl itself, so only wget is needed to get started.

When it reaches the Tailscale step, it prints a login URL and waits. Open the URL on any other device (your laptop or phone), sign in to Tailscale and approve the machine. The script then continues on its own. Once it finishes, it prints the machine's Tailscale IP and an ssh command you can use from another machine on the tailnet.

The script is idempotent, so it is safe to re-run.

Options

Set these as environment variables before the script:

Variable	Default	Description
TEST_USER	the user who ran sudo	User to set up devbox for
TAILSCALE_HOSTNAME	the system hostname	Name of the machine in the tailnet

Example:

wget -qO- https://raw.githubusercontent.com/steinwurf/test-machine/main/install-ubuntu.sh \
  | sudo TEST_USER=tester TAILSCALE_HOSTNAME=lab-box-01 bash
