Apple Mac OS X Server manual Managing the Dhcp Service, Starting and Stopping Dhcp Service

inetd and xinetd each have their own configuration files. inetd uses one file, inetd.conf, to map a given service to its executable. All standard services that inetd handles are already listed in the file. xinetd, on the other hand, uses a different configuration file for each service it provides. In the /etc/xinetd.d folder, there are configuration files for each of the services that xinetd handles. If you were to enable ftp sharing, Mac OS X will modify the configuration file /etc/xinetd.d/ftp. For more information about xinetd, see www.xinetd.org.

Managing the DHCP Service

Dynamic Host Configuration Protocol (DHCP) service lets you administer and distribute IP addresses and other configuration information to client computers from your server. When you configure the DHCP server, you assign a block of IP addresses that can be made available to clients. Each time a client computer configured to use DHCP starts up, it looks for a DHCP server on your network. If a DHCP server is found, the client computer requests an IP address. The DHCP server checks for an available IP address and sends it to the client computer along with a “lease period” (the length of time the client computer can use the address) and configuration information.

$ sudo serveradmin start dhcp
