Last time here I have talked about how to keep Debian Linux up to date and thus tighten the security of your VPS operating system. Today we will mention one more possible scenario. Although Debian is a very common operating system on servers it is not the only Linux distro found there. Another very poplar distribution is build on the Fedora core and it’s CentOS and all flavours of Fedora.
The Fedora core…
Although both Debian and Fedora are build on the Linux kernel they are not identical. The most part of the commands are the same, but there are some differences. And one such difference is in the update process. You should be already familiar with Debian’s update process and in this article I will tell you how to update your Fedora box to make it safer :)
Fedora uses YUM as it’s download and update manager and I have to say it is a very good system. I have used Fedora myself for a couple of years and I was very satisfied. The YUM package manager is able to search for packages, find dependencies and install them online and offline as well.
The very basic format of the command is yum [options] and if you want to know a lot more about the command just type man yum and you will be presented with a detailed manual page with information how to use it and what advanced options you can use.
The basic command to update your system would be yum update and it is used to update your whole system. All packages will be checked and if there are some obsolete ones they will be updated appropriately. From my experience Yum is an all in one solution and it is able to download a package from a repository and install it or you can upload a .rpm to your server and install it locally. this is not done so easily in Debian where you need to run another install command to install something from a local file, but at the end of the day it is only a matter of preference.
One importan thing I should have mentioned at the beginning is that Fedora packages end with .rpm in contrast Debian packages end with .deb. There is one more option – you can still download a source code of the software you want to install and compile it yourself without the need to use yum or apt-get at all 
Where is the Gentoo?
Well I will cover the basics of Gentoo the next time here at Icethunder.net with some more configuration infos 
Until than have a nice day and see you next time!
