Getting Started with your VMs

Introduction​

This lab will get you familiar with the VM Sandbox environment and creating a CentOS VM.

Firefox is recommended for all labs. Please note, while the VM Sandbox environment is very robust, it is not perfect. Do not expect high level of performance and anticipate that there might be some latency issues, especially if you are working off-campus.

Setting-up Virtual Machines for this Class

First, login to https://ocr.uc.edu/

Select the domain "OhioCyberRange.onmicrosoft.com" and click Next.

Go ahead and run this command:

sudo su

Enter the password above once again. Now run some of these commands:

ping www.uc.edu

A proper ping response confirms we have an internet connection. Press ctrl-c to end the ping.

Run the command

ip a

You should see results similar to what's below.

While we're at it, let's go ahead and change the hostname of your Linux VM. Call is the same name you called your VM when we provisioned it (eg. reedws-centos)

To change it,

hostnamectl set-hostname reedws-centos ### replace reedws with your username

Follow this up with a reboot to finalize both our network and hostname settings.

reboot

That'll do it for our CentOS setup for now. Let's switch to Windows.

Linux Software​

Let's install all of the software we're going to need for our class. Please install all software with it's default options.

Git​

sudo yum groupinstall "Development Tools"
git config --global user.email "username@abc.example"   ### replace email with the one on your github account
git config --global user.name "Your Name"

VS Code​

If VS Code is not already installed, Download and install VSCode from https://code.visualstudio.com/download and choose the link for the .rpm installer.

sudo rpm -i /path/to/code.rpm
