I'm having some trouble setting up my Pi to allow it to write files to my password protected NAS using transmission. I have a folder on my Synology Diskstation NAS for which I'm looking to allow my Pi to store downloaded files to, the address is smb://ServerHome/home/Media/Downloads. This folder exists already and I can read the contents of it via XBMC, however when I try to download files to it I am given an invalid permissions error. Using Putty I've tried: sudo chmod g+rw smb://ServerHome/home/Media/Downloads sudo chgrp -R debian-transmission smb://ServerHome/home/Media/Downloads But it says file or folder does not exist - even though it clearly does!! Anybody have any suggestions?
