Show HN: Cmux-SSH-here – throwaway SSH server and deep link in one npx command

Cmux-SSH-here is a tool that lets users create a temporary SSH server and a deep link with a single npx command, enabling instant SSH access without permanent infrastructure.

Background

- **npx** is a tool bundled with Node.js that lets you run JavaScript packages from the web without installing them first — it downloads and executes code on the fly. - **SSH (Secure Shell)** is the standard protocol for securely logging into remote machines and running commands. An SSH server is software that listens for and accepts those connections. - **Deep links** are URLs that open a specific action inside an already-installed app (e.g., opening a chat in Slack) rather than just a web page. - This project lets you spin up a temporary SSH server on your machine with a single `npx` command, then generate a deep link that others can click to instantly SSH into that server — useful for quick collaboration, debugging, or demos without setting up permanent infrastructure. - The novelty is combining ad-hoc SSH server creation with deep-link convenience, removing several setup steps normally required.
