This section is an example of a DHCP you can use at home or in a small business network

DHCP stands for Dynamic Host Configuration Protocol. What it really is, is a system for assigning ip addressing to clients who request it upon startup. Below is a sample script for a dhcp.conf under linux. You need to make sure that the dhcpd rpm is installed, then copy its example found in /usr/doc/dhcp. Or just type touch /etc/dhcpd.conf to create the file and then insert the text I have written below. The options are fairly self explainatory and will make a tcpip range on 192.168.5 through .20, if it seems confusing just make sure and read the documention for dhcpd.One important note do NOT start the dhcpd daemon on a production network, as you will really screw thing up!

#start of dhcpd.conf file
subnet 192.168.1.0 netmask 255.255.255.0 {
# --- default gateway
        option routers                  192.168.1.1;
        option subnet-mask              255.255.255.0;

#       option nis-domain               "domain.org";
        option domain-name              "madeup.com";
        option domain-name-servers      207.217.126.81;

        option time-offset              -5;     # Eastern Standard Time
#       option ntp-servers              192.168.1.1;
        option netbios-name-servers     192.168.1.3;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#       option netbios-node-type 2;

        range dynamic-bootp 192.168.1.5 192.168.1.20;
        default-lease-time 21600;
        max-lease-time 43200;
        #below is how to specify fixed addresses
        # we want the nameserver to appear at a fixed address
        #hardware ethernet 12:34:56:78:AB:CD; this goes between next&fixed
        host ns {
                next-server redhat.madeup.com;
                fixed-address 192.168.1.3;
        }
}
