HP-UX Remote Access Services Administrator's Guide

2 Configuring FTP
The File Transfer Protocol (FTP) is used for transferring files efficiently and reliably
between hosts over the Internet. ftp is a user interface to FTP. ftp copies files over a
network connection between the local client host and a remote server host. ftp runs
on the client host, and ftpd runs on the remote server. FTP promotes file sharing, and
implicit use of remote systems, and shields a user from variations in file storage systems.
This chapter provides information on configuring FTP and anonymous FTP, and also
describes the ftpd configuration files. The following sections discuss how to configure
the FTP daemon:
