7.2. Configuring the Services
7.2.1. Using the Service Configuration Utility
The Service Configuration utility is a graphical application developed by Red Hat to configure which services are started at boot time, as well as to start, stop, and restart them from the menu.
To start the utility, select → → from the panel, or type the command system-config-services at a shell prompt (e.g., xterm or GNOME Terminal).
The utility displays the list of all available services (i.e., both the services from the
/etc/rc.d/init.d/ directory, and the services controlled by
xinetd) along with their description and the current status. See
Table 7.2, “Possible Service States” for a complete list of used icons and an explanation of their meaning.
