websockify

> Shellvault uses a websocket to connect a client-side terminal emulator to an SSH process on Shellvault's servers. When you type a command, it goes through the websocket to the SSH client running on our servers, and the socket sends the response back to the terminal in your browser. So this gives Shellvault complete shell access to your server. It could be improved by terminating SSH at the browser, and just using the Shellvault server as a dumb proxy. Step 1: javascript ssh client - https://github.com/mscdex/ssh2 Step 2: websocket tcp proxy - https://github.com/novnc/websockify Step 3: javascript terminal emulator - https://github.com/rohanchandra/javascript-terminal Step 4: ??? Step 5: Profit EDIT: And a really roundabout way to do this is to run the dropbear ssh client inside Fabrice Bellard's in-browser Linux VM: https://bellard.org/

You can use websockify to bridge the gap: https://github.com/kanaka/websockify

A project in a similar vein is websockify ( https://github.com/kanaka/websockify ) , which makes an existing app with a TCP endpoint available over websockets.

I don't see any reason why implementing SSH in JS wouldn't be possible. You'd need a small server-side part to wrap TCP to WebSockets, but it shouldn't need to touch SSH in any way. Otherwise there shouldn't be really many obstructions. Yes, it might be slower than OpenSSH, but at least it would be secure. edit: found websockify[1], which should be enough as the server-side component. Now only client-side remains :) [1] https://github.com/kanaka/websockify
