A small back story

Within each chapter of this book, you will find an example issue that covers the common troubleshooting topics. While the focus of this book is to show the commands and concepts necessary to resolve these types of issues, it is also important to show the process around resolving them. To do this, we will explore these issues as if we were a new systems administrator who recently joined a new company.

Each issue will be presented a little differently, but each one will start with an issue being reported.
