HP-UX System Administrator's Guide: Overview

FTP FTP (file transfer protocol) is an open standard for transferring files
between computers. HP-UX, Linux, and Microsoft Windows based
computers all support ftp server and client software.
FTP is generally used in interactive mode. The user establishes a connection
between their local system (the FTP client) and the remote system (running
an FTP server). Once the connection is established, files can be transferred
in either direction between the two computers, and the directory structure
of either computer can be traversed (within the limits of the user’s access
authority) to establish a source and a destination directory for file transfers.
IMPORTANT: FTP is generally an insecure protocol and files are
transferred in the clear (unencrypted). Passwords to establish the
connection between the two computers are also sent unencrypted making
these transmissions vulnerable to interception and misuse.
SSH FTP
sftp (the HP-UX command that implements the SSH file transfer protocol)
uses ssh to provide more secure file transfers than does the ftp command.
Files are encrypted during transfer and, with some SSH FTP clients, remote
file system operations are available as well (for example, removing a file
from a remote system).
RCP
rcp (remote copy) copies files between two computers.
One of the most notable rcp features is that it can copy an entire directory,
traversing the tree as it recursively copies subdirectories and their contents.
Both computers can be remote, both can be the same system (for example,
you can use rcp to copy files from one directory to another on your local
system or on a remote system), or you can use rcp to copy files to or from
a remote system from or to your local system.
rcp can use either a .rhosts file or the Kerberos authentication system
for authenticating users.
RCP (like FTP) is generally insecure. For a more secure remote copy
protocol, see SSH RCP.
SSH RCP
scp (The HP-UX command that implements the secure shell remote copy
protocol) uses ssh to securely copy files between two computers.
HTTP Primarily used to retrieve web pages for display, HTTP can be used to
transfer files
Web Access
The HP-UX 11i version 3 operating system includes the Tomcat web server for use with
web based subsystems such as the System Management Homepage. It is therefore also
available for serving web pages that you create.
