This book covers installation, file system structure, Network, LVM, Repository Structure, NTP, Log management and many other aspects of Centos Linux. The structure of the book is very simple and easy to follow.

There are thousands of Linux distributions in the market, broadly classified on their root distribution for example CentOS, Oracle and Scientific Linux are based on Red Hat which in further based on Fedora Linux. Fedora Linux is community project sponsored by Red Hat.

CentOS is Linux distribution derived from source code of RedHat. CentOS community started its operation in march 2004. It is community supported distribution. CentOS is functionally and binary compatible with Red hat enterprise Linux. CentOS generally remove Red hat’s branding and artwork. CentOS is no-cost and free to distribute distribution.

In the chapter 4 we have discussed Graphical user interface but Linux is known for command line. As command line provides more power and flexibility. A command line interface (CLI) is a text-based user interface (UI) used to manage Linux. In chapter 5 we will discuss various ways to access the command line interface.

So far we accessed the terminal on the server locally normally servers are in the datacentres and you may have limited access to the server. Therefore, we usually access the Linux servers remotely. In this chapter will learn how to access the Linux terminal remotely on your Linux or Window PC. To access the server remotely we require two pieces of software one on the server other on the client. The most common tools to access the Linux server remotely are:

- telnet
- ssh

Telnet is old software which transfers data in plain format, hence it is not safe to use. Due to safety concerns telnet is not available by default on the server. If you have specific requirement you can still install it and use it.

ssh is the modern software for accessing terminal remotely. It transfers data in the encrypted format therefore safe to use even on the less secure network. ssh has two parts, sshd which is the server daemon that runs on the server and ssh client which runs on the client PC.
