1 Introduction to Internet Services
The HP e3000 Internet Services consist of a set of programs that help the HP e3000 computer exchange
information with other nodes on the internet. The Internet Services offered on the HP e3000 are a subset of
the Internet Services available on the HP 9000, which were previously called the ARPA Services. This
introductory chapter:
• Provides an overview of the Internet Services
• Lists the system requirements for using Internet Services
• Shows how to verify the installation of the set of configuration and program files for Internet Services
that were delivered with the MPE/iX Fundamental Operating Software.
• Lists configuration files
• Describes two configuration files that all of the Internet Services use, the protocols file and the services
file, and how to install and edit them.
At the end of this introductory chapter, there is a list of additional manuals that may be helpful.
By and large, the subset of Internet Services running on an MPE/iX system are identical to those available on
UNIX machines. There are, however, some differences between them. If you are an experienced HP-UX
system administrator and you plan to skim the information in this manual, pay attention to the
“Implementation differences” sections at the end of each chapter. They describe the important differences
between MPE/iX version of Internet Services and the HP-UX version of Internet Services.
Overview of Internet Services
Internet Services on the HP e3000 consist of eight individual services that enable the HP e3000 to
communicate with other nodes on an internetwork. The program and configuration files needed to run
Internet Services is part of the MPE/iX Fundamental Operating Software. No separate software product is
necessary to use Internet Services.
The services are briefly described in Table 1-1.
