ntsysv193If you enable/disable an xinetd service by checking or unchecking the checkbox next to the servicename, you must select File => Save Changes from the pulldown menu to restart xinetd andimmediately enable/disable the xinetd service that you changed. xinetd is also configured toremember the setting. You can enable/disable multiple xinetd services at a time and save thechanges when you are finished.For example, assume you check rsync to enable it in runlevel 3 and then save the changes. Thersync service is immediately enabled. The next time xinetd is started, rsync is still enabled.WarningWhen you save changes to xinetd services, xinetd is restarted, and the changes takeplace immediately. When you save changes to other services, the runlevel is reconfigured,but the changes do not take effect immediately.To enable a non-xinetd service to start at boot time for the currently selected runlevel, check thecheckbox beside the name of the service in the list. After configuring the runlevel, apply the changesby selecting File => Save Changes from the pulldown menu. The runlevel configuration is changed,but the runlevel is not restarted; thus, the changes do not take place immediately.For example, assume you are configuring runlevel 3. If you change the value for the httpd servicefrom checked to unchecked and then select Save Changes, the runlevel 3 configuration changes sothat httpd is not started at boot time. However, runlevel 3 is not reinitialized, so httpd is still running.Select one of following options at this point:1. Stop the httpd service — Stop the service by selecting it from the list and clicking the Stopbutton. A message appears stating that the service was stopped successfully.2. Reinitialize the runlevel — Reinitialize the runlevel by going to a shell prompt and typing thecommand telinit 3 (where 3 is the runlevel number). This option is recommended if youchange the Start at Boot value of multiple services and want to activate the changes immediately.3. Do nothing else — You do not have to stop the httpd service. You can wait until the systemis rebooted for the service to stop. The next time the system is booted, the runlevel is initializedwithout the httpd service running.To add a service to a runlevel, select the runlevel from the Edit Runlevel pulldown menu, and thenselect Actions => Add Service. To delete a service from a runlevel, select the runlevel from the EditRunlevel pulldown menu, select the service to be deleted from the list on the left, and select Actions=> Delete Service.19.4. ntsysvThe ntsysv utility provides a simple interface for activating or deactivating services. You can usentsysv to turn an xinetd-managed service on or off. You can also use ntsysv to configure runlevels.By default, only the current runlevel is configured. To configure a different runlevel, specify oneor more runlevels with the --level option. For example, the command ntsysv --level 345configures runlevels 3, 4, and 5.The ntsysv interface works like the text mode installation program. Use the up and down arrows tonavigate up and down the list. The space bar selects/unselects services and is also used to "press"the Ok and Cancel buttons. To move between the list of services and the Ok and Cancel buttons, use
