From the main page: xinetd starts programs that provide Internet services. Instead of having such servers started at system initialization time, and be dormant until a connection request arrives, xinetd is the only daemon process started and it listens on all service ports for the services listed in its configuration file. When a request comes in, xinetd starts the appropriate server. Because of the way it operates, xinetd (as well as inetd) is also referred to as a super-server.

A sample configuration file for a service is shown:

# default: off

# description: The * server serves * connections. It uses \

# normal, unencrypted usernames and passwords for authentication.

service servicename

{

socket_type = stream

wait = no

user = root

server = /usr/sbin/server

server_args = -l -a

log_on_success += DURATION

nice = 10

disable = yes

}

To start a service that isn’t running, usually all that is needed to edit the line in the configuration file changing:

disable = yes

to

disable = no

and restarting the xinetd service.
