To provide consistency among the case studies and examples
throughout Managing Systems and Workgroups: A Guide for
HP-UX System Administrators (MSW), we have developed
a sample workgroup/network to
demonstrate a variety of situations and tasks. While it is impossible to account for every possible combination
of equipment and network topography, we have tried to account for
many common configurations. The
MSW Network (Overview) | |
The MSW network has two “subnets”, joined at
a gateway computer that has two networking interface cards in it.
The subnets, known as “net1” and “net2,” use
Internet Protocol (IP) addresses in the following ranges: - net1
15.nn.yy.0 through 15.nn.yy.256 - net2
15.nn.xx.0 through 15.nn.xx.256
| | | |  | NOTE: The IP addresses used in the example network and throughout
MSW are designated using the nonspecific address components “nn”, “xx”, and “yy” to avoid conflicting with real-world IP addresses.
IP addresses do not normally contain letters. | | | | |
Throughout this book, subnets net1 and net2 are
part of a generic domain called “corporate”. Figure 2-1 “Managing Systems and Workgroups Example Network
Diagram” shows an
overview of the example network for Managing Systems
and Workgroups. The section “The
MSW Network (System by System)” gives detailed information about the systems
in the example network.

MSW Network (System by System) | |
The MSW network includes a variety of system types: server
systems, workstations, personal computers, and thin clients. There
are also several network-based printers. For details on the specific
systems listed in the preceding table, review the following descriptions
until you find the system that interests you. The MSW example network includes two server systems: - appserver
This system, a 32-way Superdome configured with
a single partition, is an applications server in the example network. It
is running HP-UX 11i Version 1. - flserver
This system, an HP9000 rp8400, is one of the key computers
in the network. Its name reflects its primary use, a file server.
It is where this workgroup stores most of its data. In addition to its use as a file server, it is also the gateway
computer between the two subnets net1 and net2.
It has two network cards, one connecting to net1 via
thin-lan coaxial cable, and one connecting to net2 via
a 10-BaseT network hub. flserver also has a printer directly
connected to it.

File Server for Workgroup. This is the computer that stores most of the data files for
the workgroup represented in MSW. It is a large, LVM configuration
with high availability features installed. This computer is the gateway system between the subnets net1 and net2. Because
of that it has two network names (flserver.net1 and flserver.net2)
and two IP addresses (one for each network interface card).
There are four workstations in the MSW example network, one
on the net1 subnet, the others on net2.
Each is a different model, and they run various versions of HP-UX
to reflect many installations in the real world where not every
computer is running the same HP-UX release. - wsj6700
