Hide Apache and PHP signature information

by mtecheasy on December 14, 2010

Apache Version 2.2, Ubuntu Server 9.04

Files to edit:
/etc/php5/apache2/php.ini
/etc/apache2/conf.d/security

When you access a page on your server that doesn’t exit, you get the following possible signature by default:
– Apache/2.2.11 (Ubuntu) PHP/5.2.6-3ubuntu4.6 with Suhosin-Patch Server at 192.168.100.158 Port 80

To remove the PHP Signature, open php.ini and find expose_php = On, and change it to Off.
– Apache/2.2.11 (Ubuntu) Server at 192.168.100.158 Port 80

To remove the Apache version number, OS name, open the security file and change the ServerTokens Full to ServerTokens Prod.
– Apache Server at 192.168.100.158 Port 80

If you don’t want any information displayed, open the security file once more and change the ServerSignature On to ServerSignature Off.
