Using and Administering Linux: Volume 3

This third edition of the popular and highly rated Linux self-study training course has been fully updated to Fedora Linux 43 with expanded and revised content, figures, and experiments. This course will prepare you to manage complex systems with ease and equip you for a new career. 

Focusing on network and other advanced services, this third edition of the final series volume builds upon the skills you have learned so far in volumes 1 and 2 and will depend upon the virtual network and the VM created there. Start by reviewing the administration of Linux servers and install and configure various Linux server services such as DHCP, DNS, NTP, and SSH server that will be used to provide advanced network services. You’ll configure your server as a router, then install and configure servers such as BIND for name services, DHCP for network host configuration, and SSH for secure logins to remote hosts.

Other topics covered include public/private keypairs to further enhance security, SendMail and IMAP and antispam protection for email, using Apache and WordPress to create and manage web sites, NFS, SAMBA, and Chrony. This volume also covers SELinux and its use in making your systems even more secure., You will learn to build RPMs to be used to distribute automation scripts. All of these services are installed on a single server host over the course of the book and by the time you are finished you will have a single server that provides these services for your network.

• Install, configure, and manage several Linux server services such as email with spam management and single and multiple web sites
• Work with NTP time synchronization, DHCP, SSH, and file sharing with Unix/Linux and Windows clients
• Create RPMs for distribution of scripts and administrative programs
