Salve a tutti,
	ho inserito l'indirizzo ip statico nel file /etc/network/interfaces:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.0.100
        netmask 255.255.225.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

Però quando avvio il sistema ottengo che eth0 è configurato correttamente:

root@debian:~# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:30:4F:13:2B:E4
          inet addr:192.168.0.100  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::230:4fff:fe13:2be4/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:675 errors:0 dropped:0 overruns:0 frame:0
          TX packets:423 errors:2 dropped:0 overruns:0 carrier:4
          collisions:0 txqueuelen:1000
          RX bytes:61271 (59.8 KiB)  TX bytes:89537 (87.4 KiB)
          Interrupt:9 Base address:0xa000

Ma non c'è nessuna rete e nessun gateway di default:

root@debian:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface

Se lancio lo script sotto init.d ottendo questo:

root@debian:~# /etc/init.d/networking restart
Setting up IP spoofing protection: rp_filter.
Reconfiguring network interfaces...ifup: interface lo already configured
SIOCSIFNETMASK: Invalid argument
Failed to bring up eth0.
done.

A cosa è dovuto? La netmask mi sembra corretta...

Grazie a tutti,
Gianluca
