You would also need to install openssh on the N900.

On the Ubuntu side, modify the /etc/network/interfaces file and add these lines:

Code:

iface usb0 inet static
       address 192.168.2.14
       netmask 255.255.255.0
       broadcast 192.168.2.255

and then restart the interface on the Ubuntu after connecting the cable

Code:

sudo ifup usb0

you should now be able to ping the N900 from Ubuntu (ping 192.168.2.15) and use ssh or sshfs to have full access to the N900's filesystem
