CentOS Howtos

This page strives to help you, our valued clients get the most from your CentOS Linux communication server. After using various distributions of Linux in the past for our Communications server, our technical team has decided to stick with the Enterprise class of  CentOS.

CentOS ( Community Enterprise Operating System) is built directly from the same source RPMS that make up Redhat Enterprise Linux, thereby ensuring that your system is very stable.

The help laid out in these pages will be specific to our CentOS installations. If you are running an older version of Linux, our Basic Guides page can be found here................ ( Upgrading to CentOS is advised. )
If you don't find an answer to your problems, email us and the solution will be added here.
