A standalone system is often not of much use. Networking enables us to exchange information and share resources with other network devices and connected computers. In this chapter, you will learn essential skills required for managing network connections from the command line. Then you will learn how to access the remote system using SSH (short for Secure Shell) and the secure transfer of files with SCP (short for Secure Copy) and rsync utilities.

In this chapter, we will cover the following:

  • Linux networking concepts
  • Using Linux networking commands
  • Managing networks with nmcli
  • Editing network configuration files
  • Configuring hostname and DNS (short for Domain Name System) resolution
