1 APPC Application Suite for HP-UX Programs
This chapter provides an overview of the applications provided in the APPC Application Suite. You use these
application programs to send and receive files, simplify network naming, check connectivity, execute commands
on remote workstations, and send messages from one workstation to another. This chapter also explains how to
configure your system to run these applications.
1.1 What Is APPC Application Suite?
APPC Application Suite is a set of command-line programs that communicate over APPC sessions. They use
independent LU 6.2 protocols to communicate with similar applications running on other nodes in SNA networks.
Each application comprises two programs: a requester program and a provider program. The applications can be
accessed from a server or from a HP-UX or Windows client.
APPC Application Suite contains the following applications:
•
ACOPY
(APPC COPY)
•
AFTP (APPC File Transfer Protocol)
•
ANAME
(APPC Name Server)
•
APING (APPC Ping)
•
AREXEC (APPC Remote EXECution)
•
ATELL (APPC TELL)
The rest of this chapter describes how to configure your system to run APPC Application Suite. The subsequent
chapters describe the programs in detail.
1.2 Configuring Your System for APPC Application Suite
You must establish links with any remote systems before running APPC Application Suite programs that
communicate with those systems.
1.2.1 Configuration Overview
APPC Application Suite includes both requester programs and provider programs. Requester and provider programs
are paired; the requester program requests services, and the provider program performs the services. A requester
program resides on the local node or on a client connected to the local node. It requests services from a provider
program residing on a partner node or on a client connected to the parther node. APPC Application Suite may be
used both to access remote providers and to provide services to remote requesters.
For example,
AFTP is a requester program that enables you to send and receive files between two computers; its
provider program is
AFTPD. Assume that AFTP resides on local node A and AFTPD resides on remote node B. To
send a file from node A to node B, you invoke
AFTP, which then communicates with the provider program AFTPD
at node B, requesting that it execute the required task.
In order for a requester program to communicate with its provider program, you must identify the target LU and
specify an SNA mode. You can supply this information on the command line or include it in a configuration file.
