Bug report: Sync ignores Linux group permissions

Recommended Posts

I want to sync a folder which has the owner:group root:system and the permissions drwxrwxr-x (775).

I've edited /lib/systemd/system/resilio-sync.service to run sync as user:group rslsync:system.

I've edited /etc/passwd so tha the user rslsync has the group system.

I've made a systemctl daemon-reload and a systemctl restart resilio-sync.

Sync runs but won't write to the folder and says it has no permission.

When I login as user rslsync I can obviously write to the folder because I have sufficient group permissions.

Only when I change the owner of the folder to rslsync Sync can write to that folder.

 

Ubuntu 18.04.2 LTS and Resilio Sync 2.6.3 installed with apt.

Update on further research:

Changing the permissions to 777 has no effect.

After changing the owner to rslsync and accessing the folder with Sync I can change the owner back to root and Sync can still access the folder. So probably Sync has some kind of internal database where it stores assumed permissions?

I don't know if this is a Resilio or Linux issue, as I run into problems with users not having write permissions despite being in the group on Linux from time to time.

Solution has been to use setfacl and give write access to the Resilio dirs to the user. Easier than changing users, systemd files or using chown over and over.

Sooo... nobody cares?

Hi,

same issue. Any ideas about this here? I chengaed the owner of the files to the user Sync is running (with netgear it is user "admin") restartet sync and then changed the owner back. The sync is fine again but like to see this solved.

Cheers,

Nils

In my testing, I was hoping that the mode bits would get synced, but they appear not to which is unfortunate.  Syncthing and Seafile to appear to sync the mode bits though.
