Configuring hosts to use a DHCP server is a simple matter of setting options for the host's network interface device such as an Ethernet card. For a Red Hat Linux host, you can use netcfg to set the host to automatically access a DHCP server for network information. On the Interface panel, click the network interface device for the host, such as eth0 for the first Ethernet card. Then click Edit. From the pop-up menu labeled Interface Configuration Protocol, select DHCP. This will set the BOOTPROTO entry in that interface's network script in the /etc/sysconfig/network-scripts directory, such as ifcfg-eth0 for the first Ethernet card. You could also manually make this entry.

Be sure to restart your network devices with the network script to have the changes take effect. On a Windows client, locate the TCP/IP entry for your network interface card, then open its properties window. Click the box labeled "Obtain IP address automatically". Then locate the Wins panel (usually by clicking the Advanced button) and select DHCP as the protocol you want to use.

On Red Hat systems, you can stop and start the DHCP server using the dhcpd command in the /etc/rc.d/init.d directory. Use the service command with the start, restart, and stop options. The following example starts the DHCP server. Use the stop argument to shut it down, and restart will restart it.

Configuration files for the DHCP server are kept in the /etc/dhcpd directory. Here is kept the primary configuration file dhcpd.conf, where you specify parameters that define how different DHCP clients on your network are accessed by the DHCP server. Global parameters apply to all clients. You can further create declarations that reference a particular client or different groupings of clients. Within these declarations you can enter parameters that will apply only to those clients (see Table 36-1). Declarations are implemented using different statements for different kinds of client groups. For example, to define a declaration for a particular host, you use the host statement as shown here:

Table 36-1: DHCP Declarations, Parameters, and Options Description Used to note if some subnets share the same networks. References an entire subnet of addresses. Provides the highest and lowest range for dynamically allocated IP addresses. References a particular host. Lets you label a group of parameters and declarations, and then use the label to apply them to subnets and hosts. Do not dynamically assign addresses to unknown clients. Whether to respond to bootp queries. Whether to respond to client queries. Length in seconds assigned to a lease. Maximum length of lease.

List of router IP addresses on client's subnet. List of domain name servers used by the client. Whether to look up and use IP addresses of clients. Denies invalid address requests. Specify the server.

Table 36-1: DHCP Declarations, Parameters, and Options Description The client's Network Information Service domain. NIS servers the client can use.
option nis-domain string; option nis-servers ip-address [, ipaddress... ];
option smtp-server ip-address [, ip- List of smtp servers used by the client. address... ]; option pop-server ip-address [, ipaddress... ]; List of pop servers used by the client.
option nntp-server ip-address [, ip- List of nntp servers used by the client. address... ]; option www-server ip-address [, ip- List of Web servers used by the client. address... ]; You use the subnet statement to inform the DHCP server of the possible IP addresses encompassed by a given subnet. The subnet statement includes the netmask for the subnet.
subnet 192.168.1.0 netmask 255.255.255.0 {
With the range statement, you specify a range of addresses that can be dynamically allocated to clients. You enter the first and last addresses in the range.
range 192.168.1.5 192.168.1.128 {
With parameters, you can specify how the server is to treat clients. For example, the defaultlease-time parameter sets the number of seconds a lease is assigned to a client. The filename parameter specifies the boot file to be used by the client. The server-name parameter informs the client of the host from which it is booting. The fixed-address parameter can be used to assign a static IP address to a client. See the Man page for dhcpd.conf for a complete listing. Clients can further be provided with information they may need to access network services, such as the domain name servers that client uses or the broadcast address. This information is provided by option statements as shown here:
option broadcast-address 192.168.1.255; option domain-name-servers 192.168.1.1, 192.168.1.4; option domain-name "mytrek.com";
