[root@localhost Packages]#

Tomar como referencia el archivo de ejemplo en
/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample

Iniciar el servicio

# service dhcpd start

Tendríamos en /etc/dhcp/dhcpd.conf :

option domain-name "unas.edu";
default-lease-time 600;
max-lease-time 7200;
subnet 192.168.2.0 netmask 255.255.255.0 {
  range 192.168.2.240 192.168.2.250;
  option routers 192.168.2.1;
}
host vmware_prueba {
        option host-name "vmware_prueba";
        hardware ethernet 00:0c:29:fd:31:25;
        fixed-address 192.168.2.249;
}

Ir al laboratorio de instalación desatendida mediante KickStart  (ks), para cerrar la practica de método de instalaciones.

La sección :

host vmware_prueba {
        option host-name "vmware_prueba";
        hardware ethernet 00:0c:29:fd:31:25;
        fixed-address 192.168.2.249;
}


Es muy útil por ejemplo para asignarle ip estáticos a impresoras u otros devices.
