222 Chapter 14 Configuring and Managing Network Services
xinetd uses a different configuration file for each service it provides. In the
/etc/xinetd.d/ folder, there are configuration files for each service 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 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.
