Technical requirements

For these recipes, we're going to use two Linux machines. We can use the client1 virtual machine from our previous recipes. We'll also use another two virtual machines running CentOS 8 2105 to cover CentOS-based scenarios (nmcli and firewall-cmd). Let's call them server1 and client2. All in all, we need the following:

  • A virtual machine running Ubuntu 20.10
  • Two virtual machines with CentOS 8 2105

So, let's start our virtual machines and let's get cracking!
