I need to disable that indexing when I enter on my root directory on a apache2 server, any tips?
Edit your apache2 configuration file which normally is on the dir: "/etc/apache2/httpd.conf".
Add the following or edit if your already have some configurations for the default web server dir (/var/www):
Options -Indexes
AllowOverride All
Order allow,deny
Allow from all
This will disable the indexing to all the public directories.
