Linux administration requires you to manage multiple systems at once--no easy task. In this course, you'll learn all about networking with CentOS 7 Linux, from configuring IP addresses to implementing Virtual Private Networks.

There is more to Linux administration than managing a single system--you have to network many systems and protect these systems from the Internet. In this course, LFCS: Linux Networking, new system administrators like you will be equipped with the skills needed to integrate CentOS 7 into a networked environment. First, you will learn how to implement persistent configuration of the IP address, gateway, and DNS settings of your system. Next, you'll learn the skills required to implement firewalls on your CentOS 7 system. Finally, you’ll learn how to implement secure tunneling to create Virtual Private Networks. By the end of this course, you'll have the expertise you need to be able to network and secure multiple systems.
