COURSE Description

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

Nothing is taken for granted, and the labs begin by downloading, compiling, and installing BIND. Students create BIND configuration (named.conf) from scratch for authoritative and recursive servers. They create zone files from scratch for authoritative masters. BIND’s DNS tools, dig and rndc, are taught 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 gaps in their knowledge and corrects misconceptions, and that it moves on to unknown topics and new material. All Men & Mice courses are hands-on, full of laboratory exercises.

DNS & BIND Week can be taken as two independent courses, DNS & BIND Fundamentals (DNSB-F) and DNS & BIND Advanced (DNSB-A). However, DNSB-W comes at a discount of $150 off the price of the individual courses, and is recommended for most participants.

  • BIND Configuration for All Course Topics

Note about content: In some courses, due to time required for other topics and participants’ interests, a topic or two may be reduced or skipped. The decision is made by the instructor with input from the participants.

Note about DNSSEC: Our three-day DNSSEC & BIND course (DNSSECB) goes much further in depth on DNSSEC, and it covers far more DNSSEC topics. For example, DNSB-W does not cover running a DNSSEC authoritative server, and nothing about administering DNSSEC keys.

Prerequisites (recommended)

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 shell 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.

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 cannot be so extremely mis-configured that it will not get an IPv4 address with DHCP. Please note the Ethernet port requirement as some laptops require an adapter for Ethernet. A computer without a physical keyboard, for example a tablet, will be a significance hindrance, is not recommended, and will additionally fail to meet the Ethernet port requirement.
