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.

Course Overview Hey everyone, and welcome. My name is Andrew Mallet, and I'd really like to introduce you to my course, the LFCS: Linux Networking. I am the owner of the Urban Penguin in the U. K., and I train and consult in Linux administration, as well as dabbling a little bit in software development. With the use of Linux on the increase you want a professional Linux certification that really tests you on what you can do, not just what you can read in a book. Both the Linux Foundation, and the Red Hat certifications are performance based exams where you are tested on a live and running system. We're going to see as we go through the course that we'll be introducing some major topics. These are going to include configuring the basic network settings, configuring routing and Network Address Translation routing, as well as adding a VPN server through to CentOS 7. By the end of the course you'll be able to fully network your system in many different situations. You will be able to secure the system and the network using firewalls and VPNs, as well as being versed within the standard network connectivity. Of course, you will need some Linux experience before you dabble with this, so we will suggest sitting the LFCS: Linux Essentials course first.
Using iptables Hello, and welcome to this presentation from Pluralsight. My name is Andrew Mallett, and I'm here as your instructor to help guide you through the module where we take a look at using iptables to instantiate our firewalls. And to be honest, we're just mirroring the objectives that we looked at in the previous module. In the previous module, we looked at using firewalld. We're going to now see how we can do the same, or achieve the same goals, using iptables. So we're going to be implementing packet filtering in configuring our firewall settings. To help you along the way, of course, we're going to have demonstrations, and we're going to see how we can start using the iptables toolset, how we can design a robust firewall. We'll be looking at installing the iptables configuration files and seeing how they can help us along, and of course, we'll be editing the default configurations to provide us the firewall goals that we need to protect our services. Let's get into our first demonstration where we take a look at using the iptables toolset.
