Zussaweb is not included in the package one gets using this howto, but the Asus headstarts points to it.

What I had to do:

cd /opt/tmp
wget http://download.sourceforge.net/sour...saweb03.tar.gz
cd /opt/share/www
tar -xzvf /opt/tmp/zussaweb03.tar.gz

and edit settings.php in /opt/share/www/zussaweb
