In this chapter, you learned how to configure some of the fundamental network services often associated with Linux. We started off with how to set up the name resolution using DNS and ended up finishing on the same topic as we added e-mail server records to DNS. Having looked at DNS, we stayed alliteratively with D and studied DHCP, thus allowing a supply of IP configuration to the network. This took us to the complexities of the different time services that are on offer with chronyd, ntpd, and ptp4l. At the end of the chapter, we looked at a simple configuration of the Postfix SMTP server on RHEL 7. This should give you a simple overview of services that you can expect to work with on a day-to-day basis with Enterprise Linux.

In the next chapter, we will see what is new on RHEL 7 and 7.1 and how to set up iSCSI storage services. You will find that the ISCSI target is now kernel-based and works very differently to the previous iSCSI target service on RHEL 6.
