Managing the xinetd Daemon

The xinetd service is implemented by the daemon process xinetd. This process has a script in /etc/ init.d that allows you to start and stop this process automatically. Be aware that by default xinetd is not activated, so if you want to use it, enable it first with the insserv xinetd command. Using this command makes sure that xinetd starts automatically the next time you boot your server; in other words, it doesn't start it immediately after you issue insserv xinetd. To start it immediately, use the rcxinetd start command. This command reads all the services' configuration files and makes sure all the services that are enabled are reachable from that moment on.

From time to time, you'll have to restart the xinetd service. This is because it doesn't ever check its configuration files. So if you have modified the services' files, make sure to activate them by using the rcxinetd reload or rcxinetd restart command.
