Sr Garcia,

Por favor, encuentre un ejemplo de mi configuracion que yo uso a mi casa
por mi beowulf privada.  Esto es por dhcpd, en /etc/dhcpd.conf, y es por
una red interna privada con IP numeros 192.168.  Nota bien los tres
secciones.  Esto funciona bien por computadores que boot en Windows o
Linux o otro con clientes dhcp -- algunos de mi computadores a casa boot
ambos.  Nota tambien los direcciones:

        range 192.168.1.192 192.168.1.224;

solamente estos estan usado para computadores no conocido por el
servidor con numeros ethernet registrado y direcciones staticos.

Espero que esto se ayuda on poquito.  Y desculpame de mi Espanol malo;
es (estoy seguro) peor que su Ingles, pero yo necesito la practica.
