ISPConfig - A popular, open-source (free) web hosting control panel.
The installer we recommend can be found here. It will guide you through the entire ISPConfig install process with command line prompts. Prior to beginning, please be sure you have installed the latest version of Debian (64-bit) on your Netsonic cloud server. Once the server has been built, SSH into it as root and run the following command -
apt-get update && apt-get -y upgrade && reboot
Once the server reboots, SSH back in as root and follow the installation instructions in the URL above.
