Browser Requirements

noVNC uses many modern web technologies so a formal requirement list is not available. However these are the minimum versions we are currently aware of:

• Chrome 49, Firefox 44, Safari 10, Opera 36, IE 11, Edge 12

Server Requirements

noVNC follows the standard VNC protocol, but unlike other VNC clients it does require WebSockets support. Many servers include support (e.g. x11vnc/libvncserver, QEMU, and MobileVNC), but for the others you need to use a WebSockets to TCP socket proxy. noVNC has a sister project websockify that provides a simple such proxy.

Installation Requirements

Install the server side, TightVNC which is a remote desktop control software that enables remote accessibility. To install, use the following yum command as shown below.

 yum -y install tigervnc-server xorg-x11-fonts-Type1

 yum --enablerepo=epel -y install novnc python-websockify numpy 

vncserver :1

Quick Start

• Download current Repo

git clone https://github.com/astro7x/GNURadio-NoVNC

• Use the launch script to automatically download and start websockify, which includes a mini-webserver and the WebSockets proxy. 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. Hit the Connect button, enter a password if the VNC server has one configured, and enjoy!

TODO

create a script to create random users to use the GNURadio-NoVNC service for a fixed timeslot and terminate/abort the connection after time slot duration. REF
