Rsync SSH : permission denied

Hi all,

I am trying to save files from my computer (running linux lite) to my ReadyNas 104.

I have created a public key (saved as ~/.ssh/id_rsa.pub) that I have uploaded in the user settings on my NAS (Accounts->user->Settings->SSH->Import public Key).

The user account I configured has R/W access on the network drive. However, when I run the following command :

rsync -r -v -s --protect-args /home/frm/Music/aTagger/ /run/user/1000/gvfs/smb-share:server=flero.local,share=music/aTagger

I get a write error message for each of the file it is trying to write. Example below of such message for the file "Coups de vents.jpg" :

rsync: mkstemp "/run/user/1000/gvfs/smb-share:server=flero.local,share=music/aTagger/.Coups de vents.jpg.r2XXu2" failed: Permission denied (13)

If I try to move files the other way around (from the NAS to the computer), it works perfectly. I am therefore probably doing something wrong in the configuration of the write access to the NAS but I am not quite sure what.

Anyone has a clue as to which direction I should be looking into ?

Thanks a lot
