Siemens V4.0 manual Client-server architecture, Shared resources

Introduction to Advanced Server for UNIX Client-server architecture

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$)
