Training

This Advanced DNS training course focuses on critical topics. These include security topics that are critical in today's Internet. DNS has exotic, out-dated, and rarely implemented features. Those are not covered. This course mixes in-depth lectures and practical hands-on labs, which each student runs on his or her own server, which we provide.

 

Material Requirements

A participant must bring a computer with an Ethernet port, a keyboard, and an SSH client. (PuTTY is an example of an SSH client for Windows). The laptop must be able to get an IPv4 address with DHCP over the port. Please note the Ethernet port requirement, as some laptops require an adapter for Ethernet.

Target Audience

  • IT Professionals, Linux users, programmers, and system administrators.

Attendee Requirements

It is strongly recommended to attend DNS & BIND Fundamentals before Advanced DNS. Even participants with extensive experience tell us that DNS & BIND Fundamentals course fills in knowledge gaps, helps them understand how topics they know actually work and why, and corrects their misunderstandings.

The labs require working on the command-line in a Linux shell. Without familiarity with basics such as cd, ls, cp, cat and using a text editor, a participant will face difficulties. While experience is strongly recommended, advanced command-line skills are not needed. For the text editor, working with vi or emacs is not required, as a simple editor, nano, is also available. An understanding of IP addressing is helpful.
