To SSH into an Ubuntu devbox over Tailscale, you establish a Tailscale connection and authenticate using a public key with the ubuntu user. This provides secure remote terminal access without exposing SSH to the public internet.

Tailscale provides more secure remote access because it creates a private network for your SSH connection. This avoids exposing your devbox to the public internet, requiring both a valid Tailscale connection and public key authentication to operate.

You need an active Tailscale connection, public key authentication configured for the ubuntu user, and the specified host and key details. These prerequisites ensure secure access for maintenance and debugging tasks.

Yes, you can use public key authentication to access a devbox when WAN access is restricted by connecting through a Tailscale network. This private network bypasses WAN restrictions to provide secure SSH terminal access.

The best way to configure an SSH alias for a Tailscale devbox is to integrate the provided host and user details into your SSH config. This enables quick connections and a consistent experience for routine admin tasks.

If your SSH connection to the remote devbox is not working, verify your Tailscale connectivity, ensure proper public key handling, and confirm host key management. These operational notes are crucial for routine admin tasks.
