CitarY si mi fichero está como sigue?El interface lo es es el interface de bucle local o el loopback, ese tiene que estar obligatoriamente en el archivo de configuración de la tarjeta de red.Código [Seleccionar]auto lo
iface lo inet loopback
¿En qué está?
CitarSi, así pediría una IP por DHCP al servidor que hay en la red. Debes tener en cuenta que el nombre del interfaz es diferente en cada sistema.
¿Si el usuario me da "dinamica" solo tengo que volcar al archivo /etc/network/interfaces lo siguiente?Código [Seleccionar]iface eth0 inet dhcp
¿qué es lo que debiera tener en cuenta? ¿o solo así como te lo pongo?
Citar¿Se pueden tener varias interfaces?Si, un equipo puede tener mas de una tarjeta de red, si se trata de un servidor proxy o un firewall, tendrá mas de una tarjeta de red.
Citar¿Es decir, con cada llamada al script puedo sobreescribir los valores o tengo que agregar al final dependiendo de lo que me de el usuario?Puedes sobreescribirlo, al final del script si todas las acciones se han realizado bien, reinicia el daemon de la tarjeta de red: /etc/init.d/networking restart.
