CentOS Overview
CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor.  CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.)  CentOS is free.

CentOS is developed by a small but growing team of core developers.  In turn the core developers are supported by an active user community including system administrators, network administrators, enterprise users, managers, core Linux contributors and Linux enthusiasts from around the world.

CentOS has numerous advantages over some of the other clone projects including:  an active and growing user community, quickly rebuilt, tested, and QA'ed errata packages, an extensive mirror network, developers who are contactable and responsive, multiple free support avenues including IRC Chat, Mailing Lists, Forums, a dynamic FAQ.

CentOS 6 Releases
July 10th 2011

The CentOS team is pleased to announce the immediate availability of CentOS-6.0 for i386 and x86_64 Architectures.

CentOS-6.0 is based on the upstream release EL 6.0 and includes
packages from all variants. All upstream repositories have been combined into one, to make it easier for end users to work with.

There are some important changes to this release compared with the previous versions of CentOS and we highly recommend reading this announcement along with the Release Notes.

There are no CD images being released with CentOS-6, however we have some CD variants in the pipeline.

Since upstream has a 6.1 version already released, we will be using a Continous Release repository for 6.0 to bring all 6.1 and post 6.1 security updates to all 6.0 users, till such time as CentOS-6.1 is released itself.

LiveCDs and LiveDVDs for i386 and x86_64 will be released the
next few days. These will bring in the ability to directly install from the live media.

There will also be a minimal install CD, that would bring up a base
machine with just enough content to have a usable platform.

In order to bring back the CentOS-4 Server CD style single iso image, an LWS variant of the main distro will be created.

And now: Have fun.

CentOS 4 Releases
The CentOS team is pleased to announce the availability of CentOS 4.9. Major changes in 4.9 include a) There is now a Preview Edition of OpenOffice.org-2 and b) Firefox is rebased to Firefox-3.1.x. These improvements along with many more are detailed in the online release notes here and upstream release notes here

Note: The upstream provider did not respin media for the 4.9 release and therefore the CentOS project will also not respin our install media. Installs moving forward will be off the 4.8 media and an upgrade will move you from version 4.8 to version 4.9. We do this to maintain compatibility with 3rd party kernel drivers which are designed to be installed as part of the installation process.

There is also a CentOS 4 LiveCD for i386. This LiveCD is a fully functional workstation and can be used as a system recovery tool as well. See this release announcement for more information. Available here.

University Of Maiduguri

In 2007, University of Maiduguri decided to look for an alternative solution to their Existing Mikrotik based Hotspot system to tackle issue of repetitive licensing. We decided to research open source solution where we tested and found Coova-Chilli to be the best and having more features, we were able to come up with a product that was developed in-house in the University. We are now proud to have our Product called "MPot" which is even at Version as of the time of this writing. The Base Operating system had to CentOS because we wanted to have the robustness and scalability of RedHat Enterprise Linux which we got from CentOS Linux. We are glad to have worked with the CentOS community and will like to thankeveryone involved on this wonder Open Source OS.
