HP Integrity NonStop H-Series - Manual (Page 19)

1 Introduction to TCP/IP Applications and Utilities
The HP NonStop TCP/IP applications are a set of client and server programs that operate on a
NonStop™ system and conform to the protocol family known as TCP/IP (Transmission Control
Protocol/Internet Protocol). These client and server programs are supported by all three NonStop
implementations of the TCP/IP protocol:
•
NonStop TCP/IP
•
Parallel Library TCP/IP
NOTE: H-series systems do not support HP NonStop Parallel Library TCP/IP.
•
NonStop TCP/IPv6
•
Cluster I/O Protocols (CIP)
(The term TCP/IP is used in this manual to refer to the protocol itself, rather than to a particular HP
implementation of it.)
You can use the client programs interactively at your terminal to connect to and communicate with
TCP/IP server programs on other machines (such as UNIX systems) in a heterogeneous network.
You can also use client programs operating on other machines to connect to and communicate
with TCP/IP server programs. It is also possible to use a HP NonStop client to communicate with
an HP NonStop server.
In addition to the clients and servers, the TCP/IP applications include the multiple-page terminal
emulation utility (TN6530) and a Simple Mail Transfer Protocol (SMTP) gateway through which
you can send and receive network mail.
Overview of Applications
The client and server applications provided with TCP/IP are:
You can use the ECHO client to test your connection to a
remote system by sending data to the ECHO server on that ECHO
system. If the connection is successful, the server returns
the data you transmitted in the sequence that you entered
the data.
You can use the PING client to test whether another host
is reachable. PING sends an ICMP echo request message PING
to a host, expecting an ICMP echo reply in return. PING
measures the round-trip message exchange time and
monitors any packet loss across the network paths.
You can use the FINGER client to request information about
users that are currently logged on to a system on the FINGER
network. The type of information and the format of the
display depends upon the service provided by the FINGER
server on the remote system.
You can use the Tracer utility to display the path taken by
IP packets on route to a network host. TRACER
You can use the FTP (File Transfer Protocol) client to transfer
files to and from a remote system that has an FTP server. FTP
In addition, you can choose and display directories on the
remote system, delete and rename files, and perform other
operations that relate to working with files.
You can use the TFTP (Trivial File Transfer Protocol) client
to transfer public files to and from a remote system. You TFTP
can transfer files to or from any system on a network that
