¿Cuál es la diferencia entre iface eth0 inet manualy iface eth0 inet static?
Gracias
iface eth0 inet static: Define una dirección IP estática para eth0
iface eth0 inet manual: Para crear una interfaz de red sin una dirección IP. Usualmente lo usan las interfaces que son miembros de bridge o de agregación, o que tienen un dispositivo VLAN configurado en ellas
Para más información lea:
Eche un vistazo al archivo /usr/share/doc/ifupdown/examples/network-interfaces.gz, puede obtener más información sobre el manual y algunos casos para usar:
# Set up an interface to read all the traffic on the network. This
# configuration can be useful to setup Network Intrusion Detection
# sensors in 'stealth'-type configuration. This prevents the NIDS
# system to be a direct target in a hostile network since they have
# no IP address on the network. Notice, however, that there have been
# known bugs over time in sensors part of NIDS (for example see
# DSA-297 related to Snort) and remote buffer overflows might even be
# triggered by network packet processing.

# auto eth0
# iface eth0 inet manual
# up ifconfig $IFACE 0.0.0.0 up
# up ip link set $IFACE promisc on
# down ip link set $IFACE promisc off
# down ifconfig $IFACE down
# Set up an interface which will not be allocated an IP address by
# ifupdown but will be configured through external programs. This
# can be useful to setup interfaces configured through other programs,
# like, for example, PPPOE scripts.
