Siemens V4.0 manual Glossary Group, Home directory, Interprocess communication IPC$, LM named pipe

Glossary

group

With user level security, a number of users (with user accounts) have common authorization for one or more shared resources. Individually assigned rights have precedence over those assigned through groups.

home directory

The directory in the file system of a multiuser system, in which a user is located after logging on to the system.

interprocess communication (IPC$)

Data exchange between processes which are active either on the same computer or on separate computers. In the second case, interprocess commu- nication takes place in a local network using the LM named pipe and Mailslot mechanisms.

IPC$

An administrative resource for controlling interprocess communication on servers. The IPC$ resource of a server must be shared before any of the following actions can be undertaken: displaying the shared resources of the server, use of the distributed applications on the server by the user.

LM named pipe

LM named pipes (also known as OS/2 named pipes) are bidirectional commu- nication channels for interprocess communication in the local network (similar to Berkeley sockets). They are not the same as UNIX named pipes.

lanman.ini

An Advanced Server for UNIX initialization file. The values in this file determine some of the parameters for the server in the local network, which deviate from the default values.

Local area network (LAN)

A local network consists of one or more servers and several clients. The server provides various services and shared resources for use by the clients. A network operating system controls all processes in the local network.

mailslot

A mailslot is similar to a mailbox. Any user in the local network who knows the name of the mailbox can send a message to it. Only the recipient can read the messages in the mailbox.
