Introduction

Welcome to 3+Open MS OS/2 LAN Manager, a local area network (LAN) for computers running the Microsoft Operating System/2 (MS ® OS/2). A local area network combines computer software and hardware to let computer users share infonnation and equipment. Each computer can work independently or in conjunction with the other computers on the local area network.

With 3+Open MS OS/2 LAN Manager, you can:

•Read, revise, and create files on other computers.

•Keep work group data in a centralized, secure place.

•Use applications with files on other computers.

•Send files and messages to other users on the local area network.

•Use printers, modems, image scanners, and other hardware across the local area network.

•Run programs on other computers from your computer.

Before You Begin

Before you start using LAN Manager, you'll need to have the right hardware, software, and documentation.

Hardware and Software

To use LAN Manager, you'll need the following hardware:

•An 80286or 80386-based personal computer, with at least one hard disk and two megabytes of RAM.

•A local area network adapter board properly configured and installed in the computer and physically connected to the local area network. See the documentation for your computer and for the adapter board for information about installing the adapter board.

You'll also need the following software:

•The MS OS/2 operating system installed on your computer's hard disk.

•The LAN Manager Netstation software installed on the computer's hard disk.

If your computer does not have the netstation software installed on its hard disk, the person in charge of your local area network can get it for you. If you will be installing LAN Manager yourself, you will need the distribution disks containing the LAN Manager Netstation software and the 3+0pen LAN Manager Installation and Setup Guide.

xii

Documentation

If the LAN Manager software has already been installed on your computer, then you are ready to start using this manual. This is where you can find the basic concepts and skills you need for using LAN Manager.

If the LAN Manager software has not been installed on your computer, then you have two options: you can ask your administrator to install it for you, or you can install it yourself with the LAN Manager installation program. If you intend to install the 3+Open LAN Manager software yourself, then you should read the 3+0pen LAN Manager Installation and Setup Guide before you read this manual.

When you have mastered the 3 +Open MS OS/2 LA!f Manager User Guide, you can use the 3+0pen MS OS/2 IAN Manager User Reference to learn more about the commands and the capabilities of the LAN Manager.

This guide assumes that you have a working knowledge of either MS OS/2 or MS-DOS, and that you are familiar with working with files and directories.

If you are not familiar with the MS OS/2 operating system, see the following manuals:

•MS OS/2 Beginning User's Guide

•MS OS/2 User's Reference

•MS OS/2 Setup Guide

If your 3+Open system package included OS/2, you may fmd these manuals along with your 3+Open LAN Manager documentation. In addition, they may be purchased separately.

LAN Manager

Overview

1-1

Chapter 1: LAN Manager Overview

This fITst chapter introduces you to the basic concepts and tenns for local area networks in general and MS OS/2 LAN Manager in particular. After reading this chapter, you'll know what LAN Manager is and see how it lets you work more effectively and efficiently by giving you access to computer resources distributed throughout your office or company. If you are already familiar with local area networks, this chapter can serve as a refresher and begin to fill you in on the specifics of how LAN Manager works.

Also in this chapter, you will be introduced to MacroCorp, Inc., a fictional fmancial services company, and its employees. Since a local area network serves a collection of computer users, the best way to illustrate a local area network is by showing how it affects a group of individuals. Each of the chapters in this guide features a different MacroCorp employee. Thus, as you learn about the different features of LAN Manager, you can also see how different types of users interact on a local area network.

LAN Manager

Overview

Local Area Networks and LAN Manager

What is a local area network?

A computer has different com:{,onents that perform different jobs: the hard disk stores files, the monltor displays information, the printer prints data. The components that you can use over the local area network, including hard disks, printers, and communication devices (such as modems), are resources.

A local area network is a group of individual computers that can communicate with one another. A local area network consists of the following items:

•Computers located in the same group of offices or buildings.

•Cables connecting the computers.

•Software that runs on each of the computers and coordinates communication between the computers.

LAN Manager is the software that coordinates communication on a local area network running MS OS/2 and DOS.

When the computers in your company or office can communicate with each other across a local area network, it makes you more efficient and your job easier. Without leaving your computer, you can use files on other computers and print your work on printers attached to other computers. This saves you the time it would take to carry floppy disks from office to office, or to look for an available printer or the right version of a report.

LAN Manager

Overview

Working with the Local Area Network

Servers share Some of the computers on a local area network operate as servers. resources The primary role of servers is to share resources with users at other

computers. Servers get their name from their role of serving the needs of local area network users. Usually, servers are the most powerful computers on the local area network.

Sharing is one of the most fundamental concepts of LAN Manager. Before users can use a resource controlled by a server, someone has to share that resource. Some resources that can be used across the local area network are

•Equipment, such as printers.

•Software, such as Microsoft Word for networks.

•Information, such as reports and spreadsheets.

Say you know that another department has a laser printer. If you could use that laser printer, you could produce better looking reports. To print your report on this laser printer without LAN Manager, you'd have to copy your reports onto a floppy disk and take the disk to the computer with the laser printer. But if the laser printer had been shared with the local area network, you could send the report from your computer directly to the laser printer. LAN Manager would even notify you when your printing job was ready for you to pick up.

Administrators keep the local area network running smoothly

Network Administrators

Every local area network has an administrator-someone responsible for keeping the local area network running smoothly. The administrator works with a server and shares items. The administrator's main job is helping you accomplish your work with your computer, including helping you learn how to use LAN Manager. Consult your administrator whenever you have a problem or question you cannot resolve on your own.

Network Netstations and Servers

When your computer is connected to the local area network, it becomes a netstation. Very little about your computer changes when it becomes a netstation on the local area network. You continue using it as you always have. Now, however, you can do more work with your netstation, gather more information from shared flIes, and print out that information more easilyon shared printers. Netstations can use resources an administrator has shared from a server.

Usually, a local area network contains many more netstations than servers. Netstations cannot share their resources or use the resources of other netstations.

Figure 1-1 shows a smaIl local area network comprising two netstations and a server with a hard disk, modem and a printer.

Network Computer Names

Each server and netstation on the local area network has a unique computer name to distinguish it from other computers on the local area network. Computer names are a way to personalize your company's computers. Instead of being just machines, they now have names and purposes. Usually, a computer name matches the department or person who uses the computer. Your company might also use a scheme for naming the servers you use.

LAN Manager

1 Overview

1-6

With LAN Manager, servers share such resources as printers, hard disks, and modems with netstations. In Figure 1-1, the server computer on the left is sharing a printer, a modem, and its hard disk with the netstation computers on the right. The netstations must have their own hard disks, but can connect to the server's shared hard disk as though it were a second local hard disk.

Logging on to the Network

After you've started your computer as a netstation, you need to log on to the local area network by typing your user name and password. Your administrator gives you your user name, which is the name by which you are known on the local area network, and your password, which is a secret word you supply to prove you are who you say you are. By logging on, you show you have permission to use the local area network.

Requiring users to log on helps to prevent unauthorized use of resources on your local area network. It keeps your valuable data and equipment secure and gives access to the resources you need.

.Connecting to Shared Resources

After you've logged on at your netstation, you can start using shared resources. In th.e terminology of LAN Manager, share and use are complementary terms: Administrators share the resources that users need, and users use the resources that have been shared by administrators.

Before you can use a shared resource, you must establish a connection between your netstation and the resource by telling LAN Manager which shared resource you want to use. Establishing a connection is like calling someone on the phone; using the connection is like the actual conversation you would then have with the person on the other end. By establishing a connection, you open a channel between your netstation and a particular shared resource.

LAN Manager

Overview

1-7

Once you've established a connection to a shared resource, working with that resource is just like using one of your own computer's resources-you use a shared directory exactly as you would one of your netstation's own directories.

For example, suppose your manager is the administrator for your local area network and controls a server. All the spreadsheets associated with your project are stored on this server. Your spreadsheet program, such as Microsoft Excel, is on your netstation.

Before you can used the spreadsheets kept on the server, two things must happen:

•The administrator-your network manager-must share the spreadsheets.

•You must make a connection between your netstation and the shared spreadsheets on the server.

Your administrator makes a point of sharing the individual spreadsheets upon starting the server. You connect to these spreadsheets whenever you need to update their contents.

Print Queues

Of course, while you're working on the local area network, so are other users. Both you and another user may want to use the same shared resource at the same time. This poses no problems with shared directories; both of you can use the same file at the same time. However, it is a problem if both of you want to print files on the same printer at the same time. When an administrator shares a hardware

device that can handle only one request at a time, such as a printer, LAN Manager creates a queue for that device. A queue collects requests to use the device and then fulfills the requests in the same order that it receives them. This eliminates competition for access to shared devices. Figure 1-2 shows how a queue works.

LAN Manager

1 Overview

1-8

Figure 1-2. How Printer Queues Work

When you use LAN Manager to send a document to a printer, or to request a connection to a communication device, you are actually sending a request to a queue. LAN Manager prints your file, or grants your request to use a communication device, when all requests that were made before yours have been granted.

Local and Network Resources

You will often see the words local and network used to describe resources on the local area network. A local resource is a resource that is attached to or part of the computer in front of you. Local resources are resources that you don't need LAN Manager to use.

LAN Manager

Overview

1-9

Network, of course, is the opposite of local. All resources on your local area network that are not part of, or directly attached to, your computer are network resources; similarly all other computers on the local area network are network computers. If you need LAN Manager to use a particular resource, then that resource is a network resource, and the server that is sharing it is a network computer.

Working with a LAN and Introducing MacroCorp

The examples in this guide are drawn from a fictitious fmancial services company called MacroCorp, Inc. MacroCorp provides investment and money-management services to a wide array of cus.tomers. The employees of MacroCorp are learning to use LAN Manager to increase the ease and efficiency of their work.

Jenny Tibbett, MacroCorp's Vice President for Investments, is starting a new series of reports on investments for the company. Since she'll be working with other people (accountants, secretaries) on these reports, she'd like to keep the report files in a shared directory on a server.

Jenny is not a LAN administrator, so her computer is a netstation rather than a server. If she puts the reports in a directory on her computer, they will not be available to other local area network users. What she does is to establish a connection to a shared directory on invest, a server computer. In this network directory she creates a subdirectory, reports, and then moves all of the reports to this subdirectory. Jenny then sends a memo to Mary Sullivan, who is a LAN Manager administrator, asking her to make sure that certain individuals will (or won't) be able to use the directory she has created.

Jenny never goes near the nvest server, but by establishing a connection to its hard disk (which has been shared by an administrator), she is able to use that hard disk as though it were a hard disk on her own computer:

Jenny Tibbett connects from .her netstation, tibbett, to the shared directory fdrive on the invest server. She then creates a subdirectory, reports, in thefdrive directory. Other netstation users who can connect to fdrive can then read the individual reports that Jenny has moved to reports, and perhaps even modify them.

Ising your

~S-DOS pplications with ,AN Manager

LAN Manager and the DOS Environment

LAN Manager operates in the protected mode of OS/2, which means it can take advantage of the operating system's expanded memory and multitasking capabilities. The DOS environment is also an OS/2 mode, one in which you can run software created for MS-DOS. You start using the DOS environment by choosing MS-DOS command prompt from the OS/2 Program Selector's list of programs. When you run your netstation in the DOS environment, you can run applications written to work with MS-DOS versions 2.x or later.

You can use LAN Manager in protected mode to create connections to shared resources, then switch to the DOS environment to use those connections with MS-DOS applications. For example, if you want to use a directory and a printer controlled by a server, you can connect to these network resources using LAN Manager in protected mode, then switch to the DOS environment to use your familiar MS-DOS wordprocessing program, such as Microsoft Word, to add information to files in the directory, and then to print them. Though you've switched from protected mode to the DOS environment, you can still use the connections you made using LAN Manager. However, you can't make or break connections to shared resources while running the DOS environment.

For more information about the DOS environment, refer to the 3 +Open DOS LAN Manager User Guide and the 3 +Open DOS Manager User's

Guide.
