Если не получается скачать, вот что внутри:-

#!/bin/bash

# A quick BASH script that installs noVNC and sets up an Xfce4 session,
# accessible through a browser on port 5901 TCP. Tested against Kali Linux Xfce4 "full" installations.
# If running this on Azure or other virtual hosting, don't foret to allow ingress TCP 5901.


# Configure the following parameters if needed:

resolution="1280x720x16"
