Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Enter the desired Name of the VM, select BSD from the Type drop-down menu, and select FreeBSD (64-bit) from the Version drop-down menu."

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

ping 192.168.1.1 -t

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In this scenario, pfSense acts as a DHCP Server, Firewall, and NAT device. It can play these roles distinctly or all at the same time simultaneously."
