Open the web browser on your own computer. Go to “http://www.whatismyip.com”. Write down the IP address that it returns. This will provide you with a way to test how access control in Apache works.
Change to the “/etc/apache2/sites-available” directory. On one of the sites that you have on your web server you will need to create a directory stanza.
Change the second directory stanza to read as follows:
Options Indexes FollowSymLinks MultiViews
allow from all
deny from your_IP_address
# This directive allows us to have apache2′s default start page
# in /apache2-default/, but still have / go to the right place
# RedirectMatch ^/$ /apache2-default/
Be sure to replace your_IP_Address with the actual IP that you discovered before.
Save the file, and reload the configuration.
sudo /etc/init.d/apache2 force-reload
With the browser of your own computer, try to access the website on the practice server. Were you able to get in?
