Trying to get my transmission-daemon to pick up files from a dropbox folder, to make remote starting easier (it's a headless system).

As far as I can tell, the settings.json file is as expected, but none of the files I place in the folder get picked up.

I have checked that dropbox is syncing correctly.

Here is the whole settings.json file, but the relevant lines are included below:

  "watch-dir": "/home/john/Dropbox/torrents",
  "watch-dir-enabled": true

Update

It appears to be a permissions issue. From /var/log/syslog:

Unable to watch "/home/john/Dropbox/torrents": Permission denied (watch.c:79)

I have tried stopping the daemon -> sudo service transmission-daemon stop -> changing permissions of folder using chown -> sudo chown -R john /home/john/Dropbox/torrents -> restarting daemon -> sudo service transmission-daemon start

Same result, however

Update 2

Permissions for the folder are:

drwsrwsrwx 2 john debian-transmission 4096 2012-04-09 19:40
