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.
