Training

DNS & BIND Week is very popular course. It is ideal for anyone starting out. It is most commonly attended by those with previous DNS knowledge, and by administrators with BIND experience.

Nothing is taken for granted, and the labs begin by downloading, compiling, and installing BIND. Each student creates BIND configuration from scratch for authoritative and recursive servers. They create zone files from scratch for an authoritative masters. DNS tools such as, dig,rndc, named-checkconf, & named-checkzone, are taught in depth and used extensively in the labs. Those with previous DNS and BIND skills report that the start of the course, which assumes nothing, fills in knowledge gaps, corrects misconceptions, and that it moves on to unknown topics and new material. This DNS & BIND Week training course is hands-on, full of laboratory exercises.

 

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

  • This course is most commonly attended by those with previous DNS knowledge, and by administrators with BIND experience.

Attendee Requirements

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.
