There is a known problem with the iLO2 console management devices causes the iLO2 to become unresponsive to certain tools including the HP XC power daemon and the iLO2 Web interface. When this happens, you will see CONNECT_ERROR messages from the power daemon.Additional symptoms include not being able to use the iLO2 Web interface and not being able to control the node’s boot options through the Onboard Administrator (OA) on HP server blade enclosures.When the problem occurs, the iLO2 is not completely dead; only parts of it are hung.You can clear up the problem using two methods:

• Completely remove power from the node by either removing the power cord or in the case of an HP server blade, removing the server from the enclosure. Wait 15 seconds and restore power to the node. This restarts the iLO2 . Of course, doing this also reboots the node.

• If you do not want to reboot the node, you can reboot the iLO2 device through the iLO2command line interface (which is not hung) as follows:

  1. Use telnet or ssh to access the iLO2 device that is hung.
  2. Log in to the iLO2. Use the standard XC user name and password you defined for your console devices.
  3. Reboot the iLO2:
     

     reset map1

How do I Hide Apache Version info?
Open httpd.conf file (located in /etc/httpd/ directory /etc/apache2/ )

Code:

vi httpd.conf

Set Apache ServerTokens to product only but don’t show version and other info:

Code:

ServerTokens Prod

This directive controls whether Server response header field which is sent back to clients includes a description of the generic OS-type of the server as well as information about compiled-in modules.

Setting this to Prod only displays Apache and nothing else.

Set Apache ServerSignature off

Code:

ServerSignature Off

The ServerSignature directive allows the configuration of a trailing footer line under server-generated documents.

How do I hide php info?
Open php.ini (located in /etc/php.ini or /etc/php5 or /etc/php4 directory)

Code:

vi php.ini

Make sure php does not display errors and other php information. Modify add setting as follows:

Code:

expose_php = Off

display_errors=Off

register_globals = Off

Also send all errors to /var/log/php-scripts-error.log and not on screen to end user. It can provide serious information to user.
error_log = /var/log/httpd/php-scripts-error.log

Restart Apache.

Code:

/etc/init.d/httpd restart

Now all php script errors are written to /var/log/httpd/php-scripts-error.log. Ask your website developers to use following commands to view log files

Code:

tail -f /var/log/httpd/php-scripts-error.log

vi /var/log/httpd/php-scripts-error.log.
