Internet super-server (UNIX)
inetd [-Dd] [-U string] [configuration_file]

In the second form, the primary group is the one specified for user_name in /etc/passwd.
The inetd daemon listens for connections on certain well-known ports. When it finds a connection on one of its sockets, the daemon decides what service the socket corresponds to and invokes a program to service the request. After that program is finished, inetd continues to listen on the socket (except in some cases, described below). Essentially, inetd lets you run one daemon to invoke several others, reducing load on the system.
When it starts, inetd reads its configuration information from a configuration file; by default, this is /etc/inetd.conf.
If any errors occur, inetd sends messages to slogger2; use slog2info to view the system log.
Internal services
The inetd daemon provides several “trivial” services internally by using routines within itself. These services are:
All of these services are UDP- or TCP-based.
Effects of SIGHUP
When it receives SIGHUP, inetd rereads its configuration file, which may cause services to be added, deleted, or modified.
The inetd daemon requires the libsocket.so shared library.
If you use RPC-based services, the librpc.so shared library must exist.
