Linux is quite popular nowadays among both ordinary users and large corporations such as Microsoft, IBM, etc. This book contains both theoretical and practical materials, i.e., theory and practice will be combined into a whole - there will be no separate large and boring theoretical chapters.
The book can be divided into four parts.
In the first part, we will talk about installing the system, consider logging in and logging out, perform some system configuration actions, and review the basics of the command line;
The second part is devoted to Internet settings, software installation, and an overview of popular programs for Linux - you will learn not only how to install programs but also which program to install, which is no less important.
The third part will detail local administration in Linux: managing file systems; booting the operating system; system processes and main user groups;
And of course, what is Linux without a server? The fourth part is dedicated to the issues of administering a Linux server in a local network - it will show how to configure DNS, SSH, DHCP, FTP servers; we will talk about integrating the server into a Windows network; about server security; and we will also set up a firewall and learn to protect the server from network attacks.
The book will be useful for readers of any level - both for those who have just become interested in Linux and for those who want to expand their skills in using this operating system. Everyone will find something useful and in demand here! Importantly, one of the distributions (along with Ubuntu), on which the work in Linux is demonstrated, is the Russian Astra Linux, certified and recommended for use in Russia.
