Many servers include support (e.g. +[x11vnc/libvncserver](http://libvncserver.sourceforge.net/), +[QEMU](http://www.qemu.org/), and +[MobileVNC](http://www.smartlab.at/mobilevnc/)), but for the others you need to +use a WebSockets to TCP socket proxy. noVNC has a sister project +[websockify](https://github.com/novnc/websockify) that provides a simple such +proxy. + + +### Quick Start + +* Use the `novnc_proxy` 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/novnc_proxy --vnc localhost:5901` + +* Point your browser to the cut-and-paste URL that is output by the `novnc_procy` + script.
