SSH root access via FileZilla? [answered]

Thanks for your answer! Like many other Jolla users, my Linux skills are somewhat lacking, and while trying to learn better I,m poking with simple things like replacing launcher icons, ring tones and similar. I found that I can do these things directly on my phone and via Putty and devel-su, but that it would be so much easier with FileZilla... that's why I'm asking. I just thought that there might be an easy way to gain root access while I'm logged in (like putty). Obviously it's not so.

SFTP-SSH with Filezilla and 'root' user was OK for me until I upgraded to SFOS 2.0.

Now passwd root is still accepted but Filezilla 'root' authentication is denied; only 'nemo' authentication is accepted.

By the way, sometimes I need to use 'root' userID because (i) 'nemo' has no permission for some folders or files, (ii) Filezilla automatically sets 'root' or 'nemo' owner for transferred files, depending on the connected userID.

EDIT: issue solved after editing /etc/ssh/sshd_config (modified and uncommented directive PermitRootLogin yes). By default, the SFOS2.0.0.10 directive was PermitRootLogin prohibit-password, which prevented Filezilla from authenticating 'root' userID with a password instead of a certificate.
