SSH tunnel from webpage

Question

Is it possible to create a SSH tunnel by JavaScript from a webpage to access resources on a internal network? Do I need a jump box for this?

Answer 1

This is called Web-based SSH, which requires a server-side component that does the actual work. So in essence, JavaScript can only go via a server that does the SSH part, while the client only transmits key-strokes to the server and processes the terminal output returned by the server.

If you are looking for such software, the following Github projects might be useful:

• ssh2 (uses node.js)
• open-ssh-tunnel
