The ntsysv utility provides a simple
interface for activating or deactivating services. You can use
ntsysv 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 one or more runlevels with the
--level option. For example, the command
ntsysv --level 345 configures runlevels 3, 4, and 5.
The ntsysv interface works like the text mode
installation program. Use the up and down arrows to navigate 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 the [Tab] key. A *
signifies that a service is set to on. Pressing the [F1]
key displays a short description of the selected service.
Services managed by xinetd are immediately affected
by ntsysv. For all other services, changes
do not take effect immediately. You must stop or start the individual
service with the command service
daemon stop. In the previous
example, replace daemon with the name of
the service you want to stop; for example, httpd.
Replace stop with start or
restart to start or restart the service.
