Configuracion de interfaces virtualesEs necesario para la gestion de configuracion estar cambiando la configuracion de las interfaces virtual; ya que sin esto no se podran probar los servicios y mucho menos configurarlos. Debemos tener en cuenta 2 Aspectos: 1. Configuracion. La configuracion de un servicio conlleva que configuremos la interface de manera que obtenga el acceso a internet de la maquina host.

Terminal Llamamos al navegador de archivos sudo nautilus

Archivo interfaces ubicado en /etc/network/ # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp

Terminal Reiniciamos el servicio sudo etc/init.d/networking restart

2. Prueba. La configuracion de un servicio conlleva que configuremos la interface de manera que se tenga un puente entre la maquina y el exterior y que esta funcione tal como se va a aplicar en la practica, eso si sobre la maquina host. Terminal Llamamos al navegador de archivos sudo nautilus

Terminal Reiniciamos el servicio sudo /etc/init.d/dhcp3-server restart Si genera algn error con el rndc.key entonces ponemos esta instruccion sudo chown root:bind /etc/bind/rndc.key

Configuracion servicio dns (bind9)Terminal Instalamos el servicio sudo aptitude install bind9 Llamamos al navegador de archivos sudo nautilus

Ahora procedemos a crear los archivos de las zonas y sus repectivas inversas.

Public namespaces are for shared # mailboxes that are managed by sysadmin. If you create any shared or public # namespaces you'll typically want to enable ACL plugin also, otherwise all # users can access all the shared mailboxes, assuming they have permissions # on filesystem level to do so. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. mail_location does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix.
