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.
