Abstract
At boot time, the system starts a number of services (programs which run in the background to perform a variety of tasks). This tool gives the administrator control over those services. See the The Start-Up Files: init sysv chapter of the Reference Manual for more information.
For each service, this is the list of items found in each column:
: click on this button to get a little explanation about that service;
On Boot: check this box if you wish this service to be automatically started at boot time[3]. Alternatively, if xinetd is installed and the service is a xinetd service, the label Start when requested will be displayed. Checking the box will then mean to activate that service in xinetd. You will also have to make sure that the xinetd service itself is activated.
: immediately starts the service, or restarts it (stop+start) if it is already running;
After pressing the or buttons, a tool tip shows you the status of the operation.
