1Preface

Advanced Server for UNIX can be used to integrate personal computers, which are

operated under MS-DOS®(also running MS Windows or MS Windows for Workgroups),

MS®OS/2 or OS/2®(referred to as OS/2 in this manual), Windows 95/98 and MS Windows

NT®operating systems, in local networks (LAN, Local Area Network and WAN, Wide Area

Network). Advanced Server for UNIX allows the operation of various systems in a network.

Advanced Server for UNIX V4.0 (Advanced Server for UNIX in this manual) provides users

with server functions for the local network. It extends UNIX®to a network operating system.

Advanced Server for UNIX corresponds to Windows NT Server. The network server is

based on systems with the operating system UNIX. Cooperation with Microsoft®has

ensured that Advanced Server for UNIX is compatible with Windows NT Server.

The operating system is generally referred to as UNIX in this manual. This term is

used generically to include all UNIX operating systems on which Advanced Server

for UNIX is installed, for example Reliant UNIX.

Advanced Server for UNIX is also used in abbreviated form as AS/X, as well as

sometimes as AS/U or Advanced Server.All of these terms are synonymous for the

same product.

The description of the entire Advanced Server for UNIX product covers several manuals.

The “Concepts and Planning” manual provides information on the structure and function-

ality of Advanced Server for UNIX and describes, among other things, the differences in

comparison to LAN Manager/X.

This manual provides information on the enhancements that are implemented in Advanced

Server for UNIX; it supplements the information in the manual entitled “Concepts and

Planning”. The installation and configuration of Advanced Server for UNIX on the UNIX

system are also described in that manual.

The “API Reference” manual contains information on the API (Application Programming

Interface) with regard to syntax and functions. It is supplemented by online documentation

which is supplied with the package for the manual pages.

The “SNMP Service” manual contains information on the installation and configuration of

an extension for the SNMP agent (Simple Network Management Protocol), which among

other things allows network events to be determined centrally. This manual is part of the

LAN Manager/X V2.2 series of manuals.

Preface Target Group

Product Manual U7613-J-Z815-6-76

The “User's Guide for MS-DOS Clients” and “User's Guide for MS Windows Clients” are

aimed at users of the MS-DOS or Windows clients. They provide information on starting up

and closing down clients, and on shared directories and printers. They also provide refe-

rences to the commands available for working with the client. The manuals “Installation

Guide for Clients”, “MS Network Client V2.2”, and “MS Network Client V3.0” describe how

to install these clients.

The manual “NetWare Connectivity” contains information on how your MS-DOS client can

work simultaneously with Advanced Server for UNIX or LAN Manager servers and with

NetWare®servers. It also contains installation and configuration instructions for NetWare

Connectivity.

1.1 Target group

This manual is intended for the system and network administrator, who is responsible for

installing, configuring, and operating Advanced Server for UNIX.

The section on “Client-server architecture” contains a short description of the client-server

architecture. The section entitled “Shared resources” contains information on which

network resources of Advanced Server for UNIX can be shared.

The section entitled “Services” introduces the services provided by Advanced Server for

UNIX. The section “Connection management” explains the terms “sessions“ as well as

“connection”. This section also provides information on the security concept of Advanced

Server for UNIX. The manual entitled “Concepts and Planning” contains conceptional infor-

mation relating to this topic.

Introduction to Advanced Server for UNIX Client-server architecture

Product Manual U7613-J-Z815-6-76

2.1 Client-server architecture

One or more server systems and several clients (workstations) are connected in a network

(LAN, Local Area Network and WAN, Wide Area Network) with Advanced Server for UNIX.

The server systems provide services and resources in the local network. In contrast, the

clients utilize the services and resources of the server and generally do not provide any

services and resources themselves in the network.

Provided they are authorized, every client can access every server system in the local

network. Advanced Server for UNIX also supports so-called trust relationships between

domains, which permit the user to access resources in other domains.

2.2 Shared resources

The resources provided by a server system for the network are known as shared

resources. Shared resources are protected against unauthorized access (for more

detailed information, see section on “Security concept”).

Advanced Server for UNIX provides users with the following types of resources, which can

be shared by one or more users in the network:

●Shared directory

●Shared printer

●Interprocess communication resource IPC$

●Network-wide administration (Resource ADMIN$)

Product Manual U7613-J-Z815-6-76

2.2.1 Names in the network

In the network, servers, domains, clients, users, and resources are assigned unique

names. The following table describes briefly the various types of names in the network.

Name Meaning

System name Name of the UNIX system

Computername, server name Each server and client in a network must have a unique

computername.

A proposed server name is derived from the system

name when it is being installed first (maximum 15

characters).

Username The administrator provides each user in a network with a

unique username for identification.

Users from other domains with which there is a

trust relationship are addressed with <domain

name>\<username>.

Sharename The administrator assigns a unique sharename to each

shared resource on a server.

Network name, UNC name The network name consists of the server’s computer

name and the sharename of one of this server’s

resources. A connection to a resource is established, for

example, with a network name.

Domain name The domain gets a domain name when you install the

primary domain controller. By default, it consists of the

first eleven characters of the system name plus the suffix

.dom (maximum 15 characters).

Introduction to Advanced Server for UNIX Shared resources

Product Manual U7613-J-Z815-6-76

2.2.1.1 System name

Each UNIX system has a unique name in the network, which can be displayed using the

command uname -n and set as the network node name using the SYSADM utility program.

In order to avoid problems, it is strongly recommended that the system names you

assign are unique throughout the network. While the same system name may

appear several times in different DNS domains, even in the same network,

Advanced Server for UNIX uses the system name internally for generating names

which must always be unique.

2.2.1.2 Computername (server name)

Servers and clients must have a unique name in the network, known as the computername.

The computername of a server is also called server name.

A proposed server name is derived from the first 15 characters of the system name when

it is being installed first. The terms computername and server name are used synony-

mously in relation to the server.

It can be changed to any name (with a maximum of fifteen characters) during installation.

The server name is stored automatically in the lanman.ini file on the server. It is part of the

network name and may only be changed after the installation using special utility programs.

For further information please refer to the section entitled “Changing server attributes” in

the chapter entitled “Administration guidelines”.

●The server name consists of up to fifteen characters: letters from a to z,

numbers from 0 to 9 and the special characters -.~!#$%^&()_{}.

●In the previous Version 2.0, the server name for the LAN Manager/X server had

the suffix .serve. Please note that both LAN Manager/X Version 2.2 and

Advanced Server for UNIX up to version 4.0A10 propose the suffix .srv for a first

installation instead.

●Since Advanced Server for UNIX V4.0B, the default server name proposed

during the first installation is built from the system name without an extension.

●In order not to run into problems when upgrading to upcoming NT/AS/X-

versions in the future, all tools requesting a server name during installation or

reconfiguration offer the DNS-compatible host name (‘uname -n‘) as the default

server name. The extension .srv can still be used, but is not recommended and

no longer offered as a default. Installation/configuration scripts now inform the

administrator about DNS-incompatible server names.
