Chapter 6: Enabling Network Connectivity
When we installed our system in the first chapter, we enabled the network interface. However, network configuration is, or can be, even more than that.
A server connected to a network might require additional interfaces for configuring other networks; for example, for reaching backup servers, performing internal services from other servers, or even accessing storage that is not presented directly via a Storage Array Network (SAN) as local drives but as, for example, Internet Small Computer System Interface (iSCSI) drives.
Additionally, a server might use redundant network capabilities to ensure that, in the event of a failure in one of the cards, switches, and so on, the server can still be reached and perform properly.
In this chapter, we will learn about how to define network configuration for our RHEL machine using different methods and perform some basic network troubleshooting.
This knowledge will be key since servers are commonly...
