Hi again,
i managed ,after a some long hours, to mount the hdd to an ubuntu installation via SATA / USB adaper.
After that i could change the setting in /etc/nas/service_startup/ssh => from disabled to enable
with a fresh boot, ssh was working again and i could log in via ssh finally! :)
Now i got the problem that the original web in /var/www/ is missing…
would anyone by so kind and upload the /var/www/ folder somewhere… this would really help me to use the mybook again…
thanks in advance!
