Internet super-server (UNIX)
|You must be root to start this daemon.|
inetd [-Dd] [configuration_file]
|You need to specify the -D option to inetd if you're running it under the control of the High Availability Manager. The HAM can see death messages only from tasks that are running in session 1, and the call to daemon() doesn't put the caller into that session. For more information about HAM, see the High Availability Framework Developer's Guide.|
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.
|The default version of the /etc/inetd.conf file contains commented-out descriptions of the services; uncomment the ones that you want to use.|
If any errors occur, inetd sends messages to slogger; use sloginfo to view the system log.
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.
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.
