vnc-over-gif

Serves screen updates as animated gif over http. Based on node-gif by Peteris Krumins and node-rfb2

Requirements

• running vnc server
• node 0.8 (see issue #2)
• netscape 2.0+

Installation

npm install -g vnc-over-gif

Usage

start server:

$> PORT=4455 vnc-over-gif

open url in the browser - http://localhost:4455/screen.gif?host=localhost&port=5900&password=secret

Interactivity

Preliminary support has been added for keyboard and mouse interactivity. To use, load the js.html file instead, like so:

http://localhost:4455/js.html?host=localhost&port=5900&password=secret

• requires Javascript, US layout keyboards
• events (including keystrokes) are sent to the remote server only when the mouse cursor is over the GIF image (otherwise they're sent to the browser).
• browser-recognised keystrokes (like Ctrl-N, Ctrl-T, etc) will only be passed through by Firefox -- other browsers don't allow these to be overridden and will fire their usual browser actions.
