Cloudynitzar is a shell script that turns your plain Debian system into a community networking cloud in a box (i.e. a full-featured Cloudy device). It might work on Debian derivatives too, like Ubuntu. Feel free to test and report!
A system with an up-to-date Debian 8 Jessie installation (Debian 7.8 Wheezy with backports may work too) with curl, lsb-release and an Internet connection.
From your Debian system run, as root:
apt-get update; apt-get install curl lsb-release
curl -k https://raw.githubusercontent.com/Clommunity/cloudynitzar/master/cloudynitzar.sh | bash -and let the magic begin!
