Security Enhanced Linux (SELinux) is enabled and running in enforcing mode by default in CentOS/RHEL based Linux operating systems, and with good reason as it increases overall system security.
Despite this there may be times when you want to temporarily or permanently disable SELinux, which is what we’ll cover here.
There are many different ways we can shutdown Windows Server 2016, in this quick guide we’ll demonstrate how to perform a power off through the graphical user interface, with command prompt, PowerShell, or even remotely.
This post will cover how to increase the disk space for a Windows Server 2016 virtual machine running in VMware, however the steps apply to any virtualization solution.
First we’ll increase the size of the actual virtual disk that is attached to the virtual machine, followed by making the required changes in the operating system in order to take advantage of the additional space from the hard disk expansion.
The server can stay online while the disk space is upgraded with this method which is ideal for most production servers, there’s no need to perform a system reboot.

Normally resetting the root password is a simple task if you’re logged in already with root privileges, however if you forget the password and need to change it things become a little more difficult.
The process has changed from CentOS/RHEL (Red Hat Enterprise Linux) version 6 to 7, as previously you would boot into single user mode and then change the password as root. From version 7 the equivalent modes are the rescue or emergency targets, however these require the root password before you can do anything which doesn’t help us here, so we’ll take you through the new process to change the lost root password.
This is also a task that you will need to know how to perform for the RHCSA exam.
The location of the hosts file in Microsoft’s Windows Server 2016 hasn’t actually changed from previous releases of the Windows operating system.
In this quick guide we will show you where to find the hosts file and how it can be modified.
Here we’re going to show you how to install Hyper-V in Microsoft’s Windows Server 2016 operating system.
Hyper-V is a hypervisor built into Windows which can be used to host virtual machines. The role can be installed either through the command line interface (CLI) with PowerShell, or through the graphical user interface (GUI). We’ll cover both of these options below, starting with PowerShell first.
Earlier this month Microsoft announced that PowerShell had been open sourced and would be available for use in Linux. As a result of this, PowerShell is now available for Ubuntu 14.04 and 16.04, CentOS/RHEL 7, and macOS 10.11.
If your first thought is along the lines of “who would use this abomination?”, then you’re in good company. My best thought at who this is targeted towards is the Windows system administrator that needs to be able to manage Linux systems as they are likely already quite familiar with PowerShell and perhaps unwilling to change.
Personally I’d look at using a tool such as Puppet for managing systems running various operating systems, however here’s how you can install PowerShell in Linux should you want to take this path.
Here we’re going to show you how to install the Internet Information Services (IIS) web server version 10.0 in Microsoft’s Windows Server 2016 operating system.
This guide will show you how to add a Nessus scanner into Tenable’s SecurityCenter using certificate based authentication, rather than standard username and password authentication.
