Technical requirements
You can continue using the virtual machine we created at the beginning of this book in Chapter 1, Getting RHEL Up and Running. Additionally, to test network communication, it might be useful to create a second virtual machine or reuse the one we created in the previous chapters for testing the Network Time Protocol (NTP) configuration, as we will use this to check for connectivity. Any additional packages that are required will be indicated in the text. Any additional files that are required for this chapter can be downloaded from https://github.com/PacktPublishing/Red-Hat-Enterprise-Linux-RHEL-9-Administration.
