Mastering Linux Network Administration

Summary

In this chapter, we covered various ways in which you can manage your system's resources and look at logs. We started with an overview of managing processes and discussed load averages. Then, we covered monitoring a system's memory. In addition, we looked at shell-based system monitors such as top and htop. We also covered investigating disk usage and ncdu, which is a neat tool that allows you to scan a filesystem and view its usage in an easy to use way. We also covered logrotate and systemd.

In the next chapter, we'll take a look at managing our Linux-based network. This will include things such as configuring DHCP, DNS, NTP, as well as using exim to send e-mail and advertising shared services over the network.
