-What you need to run this example:
-
- A modern browser supporting WebSocket, Canvas, TypedArrays.
-
- An RFB server on a virtual machine or another network accessible host.
- The server must accept RFB with anonymous logins (no passwords).
- The RFB client used as an example here does not support passwords.
-
- tcp-server.js
- Run with node. make sure websocket-example.js is in the same directory.
- This is the ws <-> tcp proxy that connects to the RFB/TCP server.
- The RFB server host and port are hardcoded into the JavaScript.
- You will want to update these.
-
- vnc.html (which links to vnc.css, ui.js, RfbClient.js, bytes.js)
- vnc.html: The application. Load this in your browser.
- RfbClient.js: Client implementing the RFB protocol.
- ui.js: user interface code: input events and painting canvas updates
- bytes.js: utility code to help process byte streams
- vnc.css: style sheet
