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: "The md5sum command will then print the calculated hash in a single line."

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

telinit 1

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: "Navigate to Main Menu | Backtrack | Exploitation Tools | Network Exploitation Tools | Metasploit Framework | Msfconsole."
