CentOS Enterprise Linux 7 Network Management

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 Mallet, 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. Now we're looking at the exam objectives for the Linux Foundation Certified System Administrator, and those of the Red Hat Certified System Administrator, 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, and 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.
