Joel Martin 10b9e1f47d Change noVNC license to from LGPLv3 to MPL 2.0 
The MPL 2.0 license is a "file-level" copyleft license vs the
"project-level" nature of the L/GPL. The intention of noVNC has
always been that it should be easy to incorporate into existing
projects and sites whether free/open or proprietary/commercial. The MPL
2.0 is designed for this sort of combination project but still
requires that any distributed modifications to noVNC source files must
also be published under the same license.

In addition, the MPL 2.0 allows the code to be used in L/GPL projects
(the secondary license clause). This means that any projects that are
already incorporating noVNC should not be impacted by this change and
in fact it should clarify the licensing situation (the exact
application of the L/GPL to web applications and interpreted code is
somewhat ambiguous).

The HTML, CSS, image and font files continue to be under more
permissive licenses (see LICENSE.txt). The included websockify python
code remains under a LGPLv3 license although the include/websock.js
file from the websockify component is now under MPL 2.0 as well.

Permission was received from other noVNC authors to make this change to their
code license on the following dates:

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).

More than 16 companies/projects have integrated noVNC into their products including Ganeti Web Manager, OpenStack, and OpenNebula. See the Projects and Companies wiki page for more complete list.

News/help/contact

Notable commits, announcements and news are posted to @noVNC

If you are a noVNC developer/integrator/user (or want to be) please join the noVNC discussion group

Bugs and feature requests can be submitted via github issues. If you are looking for a place to start contributing to noVNC, a good place to start would be the issues that I have marked as "patchwelcome".

If you want to show appreciation for noVNC you could buy something off my Amazon wishlist or you could donate to a great non-profits such as: Compassion International, SIL, Habitat for Humanity, Electronic Frontier Foundation, Against Malaria Foundation, Nothing But Nets, etc.

Features

  • Supports all modern browsers including mobile (iOS, Android)
  • Supported VNC encodings: raw, copyrect, rre, hextile, tight, 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
  • Easy site integration and theming (3 example themes included)
  • Licensed under the MPL 2.0

Screenshots

Running in Chrome before and after connecting:

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 or PocketVNC), 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!
