Hi, can't access the server via SSH anymore. Root password working fine on the webinterface but not via terminal!
ssh -l root 192.168.1.112

Non empty? What are their contents?
and can't load any settings because is nothing saved from me!
Never? Not even in the box flash when the red "save settings" warning appears?!
In Settings, Flash memory section, can't you select and load one?

So it seems that somehow the root password disappear?You didn't reply if you were able to login as other user other than root. This is because the actual (hashed) passwords are stored in /etc/shadow, and we need to determine where the issue is.As /etc/passwd and /etc/group are OK, and assuming that /etc/shadow is also OK, solving the root password is simple, just use the 'passwd' command.If however /etc/shadow is nonexistent of corrupted, you have to reenter all users passwords by using the 'passwd <username>' command (or changing the users password from within the Setup->Users webUI.The solution you found, setting ssh for password-less logins, might be temporary, as the contents of /root will vanish after a reboot. For setting that you need to use the "boot user script" under Services->User, user. The "how to customise" wiki contains a few examples on how to setup that script.If the /root folder (and its .ssh sub-folder) does not disappears after a reboot, then it is under /Alt-F/root and you will have *real* *trouble* with the next firmware upgrade!
