Syncthing permissions

Troubleshooting
1

Installed on pi3 and android, but can’t seem to get the sync to start looks like a permissions issue.

I’ve tried chmod 777 to no avail

Any help is much appreciated :smiley:

can you share following

ls -la /mnt/wd5tb0abd/syncthing/

root@DietPi:~# ls -la /mnt/wd5tb0abd/syncthing/

as you can see, whole folder wd5tb0abd is read/writable for user www-data only. You would need to give at least read permission for other or add user dietpi into group www-data.

9

I’m not sure where user www-data has come from. What’s the simplest fix?

Something along these lines?

chmod -R u+rw wd5tb0abd
10

You can start adding read permission for others to not open the folder widely :slight_smile:

chmod -R o+r /mnt/wd5tb0abd
11

ok I’ll give that a try - does it automatically apply to user dietpi or do I have to do something to tell it to apply for user dietpi?

12 
root@DietPi:/mnt/wd5tb0abd# chmod -R o+r
chmod: missing operand after ‘o+r’
13

You need to specify the path, like

chmod -R o+r /mnt/wd5tb0abd

Thanks thought it would have worked that out if I already cd into that directory - anyways seemed to have gone through now - cheers - still got the same error inside syncthing though - should I give it a reboot?

15

this should not solve permission issues, you would need to check the folders in question

16

Can you help me understand why this doesn’t just work out of the box? Do I need to be logging in using the dietpi user rather than root and installing things from dietpi-software that way?

17

It has nothing to do with the way you login. Its more the folder permission on your HDD. Somehow the whole drive seems to belong to web server user

18

so how can I just change the whole drive and everything inside it to belong to the dietpi user?

19 
chown -R dietpi:dietpi /mnt/wd5tb0abd

But I would not do that. It seems your drive is used by Nextcloud. Means, all data should belong to www-data.

Ah so Nextcloud is the culprit - ok I’m just going to format the drive and start fresh with syncthing - couldn’t login to nextcloud it would just hang
