This is a naive server implementation of the Remote Framebuffer Protocol. This is a quick'n'dirty hack, not recommended for any form of productive use.
There are a few known issues:
- It only does RAW encoding (requires lots of bandwidth!)
- It has bugs in negotiation of encoding (thus only 24 true color works)
- No security (password or other) support
- Updating the screen isn't really supported
This library contains a small sample server which can be run using npm start
First install this library and dependencies (we need png-js to read the png file) and start the server:
$ git clone git://github.com/johannes/jsnc.git
$ cd jsnc
$ npm install
$ npm start
Then connect using a VNC client. You should see the test.png image
displayed. On the console you can see output for different events.
Add the library to your project:
$ npm install --save git://github.com/johannes/jsnc.git
Now look at node_modules/jsnc/server.js for a sample client.
The following clients where tested:
- Remmina 0.9.99.1 - This works in 24 bit mode, but sometimes terminates after rendering our initial display content
- Gtk VNC Viewer 0.4 - his works with default settings
- jvncviewer - Tries to negotiate lower quality and fails
- Do you plan to support this? - No! If you send patches I might merge, but this is an experiment.
- Why is this not registered on npm? - Since I don't plan to maintain it.
- Is this ready for production? - No
- Why was this created? - Since I can.
This is trivial code after reading the RFB specification, thus no copyright is
claimed. If this perspective isn't shared MIT license can be used as fallback.
A file called MIT.txt is part of this distribution which contains those terms.
