{{Admon/important|SELinux|SELinux stands for '''Security-Enhanced Linux'''. It is a component that helps to better secure the system to protect against intrusion (hackers). Usually, SELinux is enabled upon the default install of FedoraCentOS. SELinux can be a good thing, if you take care of it and are aware that know how it is enabled or disabledworks. It For this course it is strongly recommended that you '''disable SELinux by default''' for this course, since you will be communicating with other virtual machines and can cause machines NOT because we won't have the time to communicatereconfigure it every time the labs make it necessary.}}

# Disabling SELinux on Fedora is actually quite simple, just edit the file '''/etc/selinux/config''' and change the following line set SELINUX to look like this:#* SELINUX=disabled.
