Using The File Transfer Protocol (FTP)

Using The File Transfer Protocol (FTP)
From Chapter 3, “TCP/IP Fundamentals,” you know that File Transfer Protocol (FTP) is a subset of TCP/IP and that FTP is used during the transfer of files between UNIX boxes. In recent
years, FTP has become a truly cross-platform protocol for file transfer. Because the Internet, and thus TCP/IP, use has skyrocketed, almost every client (and server) platform has implemented FTP. Windows is no exception. Its TCP/IP stack comes with a command-line ftp utility. To start the ftp utility, enter ftp at a command prompt. The result is an ftp command prompt:

ftp>

From this command prompt, you can open a connection to an FTP server and upload and download files as well as change the way FTP operates. To display a list of all the commands you can use at the ftp command prompt, type help or ? and press Enter. To get help on a specific command, type help, a space, and then the name of the command. 
     In the following sections, you will get an introduction to uploading and downloading files because every network technician and administrator needs to know how to do this. As they come up, the specific commands necessary to perform those two operations will be discussed, as well as commands that relate to those processes. But first, let’s look at how to start the process.
