Michael Sinatra, ESnet

Michael Sinatra is a network engineer with the Energy Sciences Network (ESnet) in Berkeley, CA, where he specializes in DNS, DNSSEC, IPv6 adoption, and scientific and high-performance networking. Prior to ESnet, Michael worked for the central networking group at UC Berkeley for over a decade. He has been interested in DNS for a long time and attempts to make coherent contributions to various BIND and DNS mailing lists and forums
Abstract: Troubleshooting DNS before DNSSEC was hard enough, and it was made more difficult when people tried to troubleshoot complex DNS problems using old tools like nslookup. With DNSSEC, the number and complexity of DNS issues makes it imperative that DNS admins understand how to use the tools available to them. This tutorial explains how to use (and interpret) tools like dig, dnscap, dnsviz, and others. It covers these specific topics (not necessarily in this order or structure):



o Basic DNS troubleshooting with dig

o (maybe) Using the sigchase functionality in dig (not in the current slide deck)

o Visualizing DNSSEC with dnsviz

o dnscap and nmsg: Specialized packet capture tools for DNS and what they can do for you

o Understanding the troubleshooting process and troubleshooting hard issues
