HP-UX System Administrator's Guide: Overview HP-UX 11i v3 (B3921-90011, September 2010)

Windows based system. In addition to the following protocols, applications and custom programs
can transfer files using inter process communication (via system calls):
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.
Remotely Mounted File Systems
HP-UX 11i version 3 implements several ways to share file systems and directories between
multiple computers. These include:
NFS NFS (Network File System) allows you to export file systems or directories from a
server to a pre-defined set of servers which in turn will mount the exported file system
so that users and processes of those servers can access the remotely mounted file systems
as if they were local file systems.
