Abstract
So far we have shown you some of the basic features of Linux, but one of the most critical features is networking. It is via networking that your host talks to other hosts and your applications communicate with your users and the world. In this chapter, we will describe how to set up your host’s networking and then how to protect that network from attackers using a firewall.
