Over the last years Red Hat always had a problem with their software management. Debian had apt, Suse settled on yum but Red Hat tried several software management tools. For now they seem to have settled on yum as well. So this page is about Red Hats implementation of yum. Yum stands for Yellowdog Updater, Modified and works with repositories to manage RPMs which is the format most software on Linux systems is packed in. In this page you'll also find some references to the original rpm command the yum commands are based on.

Security Enhanced Linux is an additional method to protect your system, besides updating and a firewall. It is a set of security rules that determine which process can access which files, directories, ports etc. Every file, process, directory and port has a special label called a SELinux context. There a several contexts, but the most interesting one is the type context, which always ends with “_t”.
This article shows some information and commands to work with SELinux. When you encounter a issue on a SELinux enabled system, you should always ask yourself the question, “Could this be caused by SELinux”. So dealing with that question will be the first part.
After that more information will be given about SELinux modes, configfiles and commands.
