Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows:

An example for such a naming standard would be "_customername_user".

A block of code is set as follows:

// Realm Id can be: 0 - Local, 1 - LDAP, 2 - Web Auth 
if ( ( $realm_id < 0 ) || ( $realm_id > 2  ) ) { 
   // The realm id will be local unless a valid id was given 
   $realm_id = 0; 
} 

Any command-line input or output is written as follows:

cd /var/www/html/cacti/cli

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Select LDAP Authentication from the Authentication Method drop-down box."

Warnings or important notes appear like this.

Tips and tricks appear like this.
