Key servers are examined, including Web, FTP, CUPS printing, NFS, and Samba Windows shares. Network support servers and applications covered include the Squid proxy server, the Domain Name System (BIND) server, DHCP, distributed network file systems, nftables firewalls, and cloud computing. The book is organized into five parts: getting started, services, shared resources, network support, and shells. Part 1 focuses on basic tasks such as installing the Ubuntu Live Server, configuring networking with Netplan, systemd-networkd, and NetworkManager, managing software from the Ubuntu Snap and APT repositories, and basic usage for the desktop and the command line interfaces. Part 2 examines Internet servers as well as how services are managed by systemd using unit files. Configuration and implementation of the Postfix mail server, the vsftpd FTP server, the Apache Web server, as well as news and database servers are covered in detail. Part 3 deals with servers that provide shared resources on a local network or the Internet.
