10.1 Introduction

BIND name servers, particularly busy ones, can log a tremendous volume of messages. Many administrators are so cowed by the quantity of messages that they simply abandon trying to track them. Knowing how to sift and sort the messages, as described in Recipes Section 10.4 to Section 10.9, can help you keep up.

The recipes later in the chapter describe how to use dig, the Swiss Army Knife of DNS query tools. The latest versions of dig will trace name resolution, send TSIG-signed queries and more, all with a few command-line options.
