Video description

Over 10 Hours of Video Instruction

Learn hands-on how Linux systems communicate and how they are networked together in real-life environments.

Overview:

Linux Networking - Basics and Beyond focuses on using Linux as a server. Most servers in today’s networks and on the cloud run Linux in some form or another. For this to work, the servers’whether physical or virtual—need to be networked together. With over 8 hours of deep-dive discussions and demos, this video course demonstrates the core concepts of configuring networking on different Linux server distributions with an emphasis on giving you the expertise you need to succeed in your career.

Topics Include:

  • Setup and Networking 101 Initial system setup provides recommendations, prepares our systems, and demonstrates how to work with the terminal and text editors. It covers networking concepts including computer networking basics, TCP/IP, the OSI Model, and more.
  • Networking Services including the actual networking service used by Debian, networkd and NetPlan used by Ubuntu, and NetworkManager used by Fedora, RHEL, and CentOS.
  • Commands and Configurations We’ll spend a lot of time here on commands such as ip, ping, dig, and nmcli, as well as hostnames and DNS.
  • Connecting between Hosts with the Command Line introduces tools such as SSH, SFTP, rsync, smb, and additional networking tools and services such as wget and curl.

Skill Level:

  • Beginner, Intermediate

Course Requirement:

  • Basic understanding of how to download and install Debian (as a server) into a virtual machine. Examples at: https://www.prowse.tech
  • Knowledge of how to set up a virtualization platform such as VirtualBox (or other favorite program). Example: https://www.prowse.tech/virtualbox/
  • Ability to work with a Linux editor: vim, nano, etc... (The instructor will focus on vim). Vim introduction: https://www.prowse.tech/vim/
  • A virtualization platform of your choice. For example, VirtualBox: https://www.virtualbox.org/wiki/Downloads, or VMware Workstation, KVM, and so on. It is recommended that you utilize NAT mode and not bridged mode. If using VirtualBox, create and select “NAT Network” for your virtual machines’ networking connectivity.
  • At a minimum, download and install the following Linux operating systems into virtual machines: Debian (as a server, no desktop environment): https://www.debian.org/distrib/; and at least one Linux client with desktop environment (Debian, Ubuntu Desktop, Fedora Workstation, etc.) These operating systems will need to be able to communicate with each other and connect to the Internet.
