  • Oracle Virtualbox Installation, Setup, and Ubuntu Introduction
    ORACLE VIRTUALBOX INSTALLATION, SETUP, AND UBUNTU INTRODUCTION • VirtualBox is a hardware virtualization program. • Create virtual computers aka virtual machines. • Prototyping, sandboxing, testing. • The computer that VirtualBox is installed on is called the “host”, and each virtual machine is called a “guest”. PREREQUISITES Since virtual machines share resources with the host computer, we need to know what resources we have available on our host. • Click “Type here to search”. • Search for “System Information”. • Note the number of processor cores and the amount of RAM installed in your host. PREREQUISITES • Expand “Components”. • Expand “Storage”. • Select “Drives”. • Note the amount of free space available on your host. Every computer is different, so how we will need to balance these resources between our host and guest systems will differ. DOWNLOADING VIRTUALBOX • VISIT VIRTUALBOX.ORG • SELECT THE CORRECT PACKAGE • CLICK THE DOWNLOAD LINK. FOR YOUR HOST. INSTALLING VIRTUALBOX • Browse to where you downloaded VirtualBox and run the installer. • All default options will be fine. Simply follow the prompts. INSTALLING VIRTUALBOX • CLICK “FINISH”. • VIRTUALBOX INSTALLED! SETTING THINGS UP Before we build our first virtual machine, we need to download an operating system to install as our “guest”. • Visit Ubuntu.com • Click “Download”. • Select the current Ubuntu Desktop “LTS” release. • LTS releases focus on stability rather than cutting edge features. SETTING THINGS UP • IN VIRTUALBOX, CLICK “NEW”. • NAME THE VIRTUAL MACHINE. SETTING THINGS UP Here’s where we will need the system resources information that we looked up earlier. Each virtual machine functions like a separate computer in and of itself and will need to share RAM with the host.

  • USING the ZERTO RED HAT CLUSTER MANAGER ZVR-RHC-5.5U3 Rev 01 Dec2017
    USING THE ZERTO RED HAT CLUSTER MANAGER ZVR-RHC-5.5U3 Rev 01 Dec2017 Using the Zerto Red Hat Cluster Manager, you can protect a Red Hat Cluster that is comprised of two virtual machines sharing a disk and is managed by Red Hat Clustering Services. Using Jenkins infrastructure hosted by Docker on a Linux virtual machine, Zerto Red Hat Cluster Manager periodically checks the status of the active and passive hosts. If they have changed, the Zerto Cluster Manager: ■ Pauses the VPG that contains the newly passive virtual machine, also known as the passive node. ■ Resumes the VPG that contains the newly active virtual machine, also known as the active node. ■ Forces a sync to ensure that the newly active virtual machine, the active node, is fully synchronized with the recovery site. You can also manually perform the tasks that the Zerto Red Hat Cluster Manager performs. This document describes the following: ■ “Zerto Red Hat Cluster Manager Requirements”, on page 1 ■ “Installing and Configuring the Zerto Red Hat Cluster Manager”, on page 2 ■ “Upgrading a Docker Container”, on page 3 ■ “Protecting a Red Hat Cluster with the Zerto Orchestrator”, on page 4 Zerto Red Hat Cluster Manager Requirements ■ The Zerto Red Hat Cluster Manager works with: ■ Zerto Virtual Replication 4.5 U1 and higher. ■ vCenter Server only. ■ Docker 1.10 and higher. ■ The shared disk in the cluster in the recovery site must be defined as an eager zeroed thick disk. Use this disk for preseeding after the VPG is created. ■ One task in the Zerto Red Hat Cluster Manager can work with a maximum of two nodes.

  • Labtainers Student Guide
    Labtainers Student Guide Fully provisioned cybersecurity labs December 1, 2020 1 Introduction This manual is intended for use by students performing lab exercises with Labtainers. Labtain- ers provide a fully provisioned execution environment for performing cybersecurity laboratory exercises, including network topologies that include several different interconnected computers. Labtainers assume you have a Linux system, e.g., a virtual machine appliance described below. If you are accessing a Labtainers VM via a web browser, you can skip to section2. 1.1 Obtaining and installing Labtainers The easiest way to obtain Labtainers is to download one of the pre-configured virtual machines from https://nps.edu/web/c3o/virtual-machine-images, and import it into either Virtu- alBox or VMWare. Follow the brief instructions on that download page. When you first boot the resulting VM, Labtainers will take a moment to update itself. You are then provided a terminal that includes some hints, and can be used to run Labtainers. Note that the VM's Ubuntu Linux distribution is configured to NOT automatically perform system updates. It may prompt you to download and install updates. That is typically not necessary and may tie up your network bandwidth. Yes, we are suggesting you not update your Linux VM unless and until you have the time and the bandwidth. You may now skip to section2. 1.2 Alternatives to the Labtainers VM Appliance Skip this section and go to section2 if you are using a Labtainers VM appliance or accessing Labtainers remotvely via a browser. Please note that Docker runs as a privileged service on your computer, and Labtainers containers run as privileged containers.
