File Transfer Protocol is a m ethod of downloading files from and uploading files to another system using TCP/IP over a network. File Transfer Protocol is the name of a client/server protocol (FTP) and a client utility (ftp) that invokes the protocol. In addition to the original ftp utility, there are many textual and graphical FTP client programs, including most browsers, that run under many different operating systems.

There are also many FTP server programs.. 19 19 . 644 19 FTP: Transferring Files Across a Network Introduction First implemented under 4.2BS D, FTP has played an essential role in the propagation of Linux; this protocol/program is frequently used to distribute free software. The term FTP site refers to an FTP server that is connected to a network, usually the Internet.

FTP sites can be public, allowing anonymous users to log in and download software and documentation. In contrast, private FTP sites require you to log in with a username and password. Some sites allow you to upload programs.

. ftp and vsftpd Although most FTP clients are similar, the servers differ quite a bit. This chapter describes the ftp client with references to sftp, a secure FTP client. It also covers the FTP server that Red Hat uses internally and offers as part of its distribution, vsftpd (very secure FTP).

FTP is not a secure protocol. All usernames and passwords exchanged in setting up an FTP connection are sent in cleartext, data exchanged over an FTP connection is not encrypted, and the connection is subject to hijacking. FTP is best used for downloading public files.

In most cases, the OpenSSH clients, ssh (page 627), scp (page 630), and sftp (page 631), offer secure alternatives to FTP..
