Even configuring the interfaces for a static address, like the following:

iface eth0 inet static
address 192.168.1.201
netmask 255.255.255.0
gateway 192.168.1.245

I cannot get the interface working. It works for a few seconds, and then some 
process resets it and eth0 looses its address. I've checked but I've got no 
dhcp/network process running, so I'm not able to understand who and why is 
resetting the interface.

Any idea?

Thanks,
Luca
