Linux

The Linux documentation is based on the distro Centos unless otherwise mentioned. This means it should be at least good for Red Hat and Fedora too.

The subjects are:

Install	Install/Epel	Install/Software
Network	Network/Change ip	Security
Security/Encrypted disk	Security/Login	Security/Selinux
Security/Ssh in scripts	Services	Services/Automount
Services/Ups	Virtualization	Virtualization/Usb
