The setup instructions provided by Ajenti.org for Ubuntu systems are simple to follow, and work perfectly on the Cubieboard2 running Linaro (Lubuntu) 13.04. Here is a quick walkthrough just to demonstrate the capability.

wget http://repo.ajenti.org/debian/key -O- | apt-key add -
echo "deb http://repo.ajenti.org/ng/debian main main ubuntu" >> /etc/apt/sources.list
apt-get update && apt-get install ajenti
service ajenti restart

After logging in, Ajenti will take a moment to load, and then you will come to the Dashboard, shown here:
