I'm using Static IP/root/dremabox as login and password/port 21.
Are you sure the ip address hasn`t changed ? Go to menu > information > network, to check the ip address.
Does the box have an active internet connection ?
There shouldn`t be a password on the image. just type root as the user.
You can set a password with this plugin enigma2-plugin-systemplugins-setpasswd_2.0_all.ipk - Copy it to a usb stick, insert into receiver, follow on screen instructions.
