Transsmision 3.00.8 - permission denied

Many of Poussin's older apps have a problem because of a change to the defaults in Samba.  At some point, insecure wide links became blocked in Samba by default, and that got into a ReadyNASOS update when Samba was updated.  It is there as a security measure, to prevent inadvertent opening of a back door.  In some apps, Poussin uses wide links (symlinks outside of a share path) to make it possible for files associated with the add-on to be accessed without going into SSH to access a folder in /apps.  When the default location can be changed, as in your case, that's usually the best way to do it.  But if the location is hard-coded, as is often the case for configuration files, then you can create /etc/frontview/samba/addons/addon.conf with the following entries (shown here with ddclient as the app, and also the share name, that needs it).

[global]
allow insecure wide links = yes
unix extensions = no
[ddclient]
  follow symlinks = yes
  wide links = yes

I believe that this poiint that unix extensions = no is the default, but I added it in case that ever changes, since allowing insecure wide links and unix extensions are mutually exclusive.  /etc/frontview/samba/addons/addon.conf is the best place for it, as it is not overwritten by OS updates.  It's also not over-written by an OS re-install, so don't mess it up to a point that would be needed.
