Conventions
These topics use the following conventions to indicate required and variable files, commands, and text.
Variable components appear in italics within angle brackets (<>). These components are represented by generic names, and must be changed to match the name used in your system.
An asterisk (*) also indicates a variable component. It is typically used to indicate a variable string that might be changed by the administrator. For that reason, it cannot be classified using a generic variable name.
Carefully follow the instructions listed in this guide, and be sure you have a thorough understanding of what is required and what is optional before completing each step.
