From iPod Linux homepage:
"(...) iPodLinux is an open source venture into porting Linux onto the iPod (http://www.apple.com/ipod/). So far, we have successfully ported a customized uClinux (http://www.uclinux.org) kernel to the iPod, and written a simple user interface for it dubbed podzilla. Additional applications and modules have been written, adding many capabilities not found in Apple's firmware."

Whar is XGL?

It supports hardware acceleration of all X, OpenGL and XVideo applications and graphical effects by a compositing window manager such as Compiz or Beryl. The project was started by David Reveman of Novell (SUSE) and first released on January 2, 2006." ( Font: Wikipedia.org )

eAccelerator description:
"eAccelerator is a free open-source PHP accelerator, optimizer, and dynamic content cache. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times." (Font: eAccelerator )

eAccelerator auto installer should work perfectly on any cPanel server, there are lots of sanity checks built in to prevent any possible issue or destruction.

Download and run eAccelerator autoinstaller:
# wget http://tutorials.medialayer.com/cPanel/eaccelerator.sh
# chmod 700 eaccelerator.sh
# ./eaccelerator.sh

Note: The php.ini gets backed up before it is modified, you can get it back..

Description:
When you run this Perl script, it will then run an netstat command check how many times each IP is connected and if there are more then the number of connections you specified then it will automatically run a command in APF for the IP to be banned.

chmod 0700 install.sh
./install.sh
