Building Linux Servers: DHCP, DNS, and Directory Services

Video description

13+ Hours of Video Instruction


Building Linux Servers: DHCP, DNS, and Directory Services LiveLessons provides a hands-on experience for both new technicians and more experienced technicians, specifically with networking technologies including the Dynamic Host Configuration Protocol (DHCP), the Domain Name System (DNS), and directory services (DS), also known as a kind of identity management technology. Through the use of hands-on demonstrations, Dave imparts his considerable knowledge and experience in a manageable way. By the end of the course, viewers should have a more in-depth understanding of how computer networking operates, as well as how to configure these technologies.

Topics include

Module 1: Virtualization and Linux Preparation
Module 2: DHCP
Module 3: DNS
Module 4: Directory Services

Skill Level


Learn How To
  • Install commonly used Linux distributions as virtual machines
  • Install a Linux-based DHCP server, configure it to supply TCP/IP information to clients, and test its functionality with various client computers
  • Build a Domain Name System (DNS) server, configure it to provide name resolution within a Linux domain, and test it with client computers
  • Install and configure directory services within Linux, create basic user accounts, and test the functionality of the server from client computers
  • Use several systems administration tools in Linux
  • Test and benchmark the DHCP, DNS, and directory services servers
  • Configure, on a basic level, these servers in containers and in the cloud
Who Should Take This Course
  • Aspiring systems administrators
  • Anyone who wants to learn more about Linux, especially Linux servers
Course Requirements
  • Basic Linux command line knowledge (cd, ls, mkdir, etc.)
  • Basic computer knowledge (a good primer on computers, such as CompTIA A+)
Lesson Descriptions

Module 1, “Virtualization and Linux Preparation,” prepares the virtualization environment and systems so you can work with DHCP, DNS, and directory services. The first lesson explains how to prepare a virtualization platform and the virtual machines that will contain the Linux operating systems. The second lesson walks you through installing some commonly used Linux distributions into the virtual machines. Connecting via SSH to the virtual machines is also covered.

Module 2, “DHCP,” provides an overview of how Dynamic Host Configuration Protocol (DHCP) works, how to install and configure DHCP, work with DHCPv4 and DHCPv6, and verify that everything functions according to plan.

Module 3, “DNS,” introduces the Domain Name System and shows how to prepare a system to work as a DNS server. Installation and configuration of DNS to the Linux server are covered, as well as working with dynamic DNS (DDNS).

Module 4, “Directory Services,” demonstrates how to set up an open-source solution for directory services. This module introduces directory services and then prepares, installs, and sets up a directory services server. The creation of users and groups are discussed, as well as working with policies. This module also covers connecting client systems and logging in with new user accounts. Finally, this module addresses redundancy, containers, and the cloud.
