Goal
I have a Raspberry Pi 3 with Raspbian and I want to make it a torrent seedbox by using Transmission. I followed all kinds of guides on the internet to solve problems I had on set-up and now everything is working, except starting Transmission on boot.
I read from How to enable transmission-daemon start at startup? that Transmission should automatically install a script on boot in /etc/init.d/transmission-daemon, which is indeed there. I applied the solution given in that answer, but to no avail.
Permissions
I think I have permissions set up wrong, because I can only access Transmission's webportal if I start sudo service transmission-daemon start as 'root' user (sudo su) and not when I run that command as user 'pi'.
NTFS external harddrive
Because I had write problems to my external ntfs drive, I tried all kinds of suggestions from different guides, which resulted in many user ownership changes to folders and files. Now I don't know which files I should chown to pi and which to debian-transmission. (I solved Error: Permission denied by umount /media/pi/Elements my drive, sudo mkdir /mnt/Elements and mount -t ntfs-3g /dev/sda1 /mnt/Elements, from: How to mount NTFS drive on a Raspberry Pi B, and then add the drive to sudo nano /etc/fstab with dev/sda1 /mnt/Elements ntfs-3g defaults,nofail 0 0).
Question
I identified that the following files are important for user permission:
/etc/init.d/transmission-daemon/etc/transmission-daemon/settings.json(withrpc-bind-address": "127.0.0.1)/mnt/Elements/transmission/{downloads,incomplete}(path to your download folder)
Also I set /etc/init.d/transmission-daemon: USER=pi
- Which folders and files I have to
chownorchmodtopiordebian-transmission?
I also tried sudo usermod -a -G pi debian-transmission and sudo usermod -a -G debian-transmission pi, but to no avail. (Obviously I'm a beginner who doesn't completely understand user permissions).
Edit 1:
It might have to do with that ls -l /mnt/Elements/transmission/ is set to root:
total 0
drwxrwxrwx 1 root root 0 date time downloads
drwxrwxrwx 1 root root 0 date time incomplete
However sudo chown -R pi:pi /mnt/Elements/transmission (or pi:root) doesn't change it, even after sudo chmod -R 755 /mnt/Elements/.
