Joel Martin 1af3e54bef Make WebSocket encrypt setting default to page protocol. 
I.e. if the page is https:// then the WebSocket encrypt setting will
default to wss:// (TLS encryption).

Note that since noVNC settings are saved in cookies, this will only
affect first load. If you have already loaded the page, then the
encrypt setting will be whatever you last set it to.

noVNC: HTML5 VNC Client

Description

noVNC is a HTML5 VNC client that runs well in any modern browser including mobile browsers (iPhone/iPad and Android).

Notable commits, announcements and news are posted to @noVNC

There are many companies/projects that have integrated noVNC into their products including: Ganeti Web Manager, Archipel, openQRM, OpenNode, OpenStack, Broadway (HTML5 GDK/GTK+ backend), OpenNebula, CloudSigma, Zentyal (formerly eBox), SlapOS, Intel MeshCentral, Amahi, Brightbox, and LibVNCServer. See this wiki page for more info and links.

Features

  • Supports all modern browsers including mobile (iOS, Android)
  • Supported VNC encodings: raw, copyrect, rre, hextile, tightPNG
  • WebSocket SSL/TLS encryption (i.e. "wss://") support
  • 24-bit true color and 8 bit colour mapped
  • Supports desktop resize notification/pseudo-encoding
  • Local or remote cursor
  • Clipboard copy/paste
  • Clipping or scolling modes for large remote screens

Browser Requirements

  • HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS Safari, Opera 11+, Internet Explorer 9+, etc.

  • HTML5 WebSockets: For browsers that do not have builtin WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in WebSocket support.

  • Fast Javascript Engine: this is not strictly a requirement, but without a fast Javascript engine, noVNC might be painfully slow.

  • I maintain a more detailed browser compatibility list here.

Server Requirements

Unless you are using a VNC server with support for WebSockets connections (such as x11vnc/libvncserver), you need to use a WebSockets to TCP socket proxy. There is a python proxy included ('websockify').

Quick Start

  • Use the launch script to start a mini-webserver and the WebSockets proxy (websockify). The --vnc option is used to specify the location of a running VNC server:

    ./utils/launch.sh --vnc localhost:5901

  • Point your browser to the cut-and-paste URL that is output by the launch script. Enter a password if the VNC server has one configured. Hit the Connect button and enjoy!
