Who This Book Is For

This book is ideal for administrators who need to learn the networking abilities of Red Hat Enterprise Linux 7. You may not be a Linux administrator already, but you will need to be able to test files in Linux and navigate the filesystem.

What You Will Learn

• Master the new time daemon, chronyd, and understand why it is used over the more traditional NTP
• Delve inside the workings of the kernel-based iSCSI target that shares disks on your network
• Share data with your Windows network and make use of their users and groups for authentication, without the need to replace your existing infrastructure
• Shield your users and data from the ever-present dangers that exist on the Internet by implementing and understanding SELinux
• Deploy Apache 2.4 and make use of its new features

In Detail

Red Hat Enterprise Linux (RHEL) is the most popular Linux distribution currently being used and can be deployed on many platforms. Enterprises that have a large number of systems need to be interconnected, configured, and managed effectively. RHEL networking lets you accomplish these tasks easily.

This is a highly-detailed guide to help with your deployments on RHEL 7 or CentOS 7. This book, based on RHEL 7.1, will introduce to you the fundamentals of networking your systems. You will learn the use of new consistent names to identify your network cards. Soon, you will move on to configuring the basic plumbing of your network, setting up time, network address assignment, and name resolution. Last, the focus moves to configuring the new kernel-based iSCSI target services on RHEL 7 and using the service to host storage area networks.
