### My YunoHost server
**Hardware:** Kimsufi KS4
**YunoHost version:** 3.5.2.2
### Description of my issue
Hello everyone,
I’d like to add a share to the app Syncthing, using a user folder, or a Yunohost backup folder.
For example:
```auto
/home/yunohost.multimedia/$user
/home/yunohost.backup/archives/
```
I’ve got those errors:
```auto
2019-06-25 12:10:25: Loading ignores: open /home/yunohost.backup/archives/.stignore: permission denied
2019-06-25 12:10:25: Failed to create folder marker: stat /home/yunohost.backup/archives/.stfolder: permission denied
2019-06-25 12:10:25: Error on folder "Backup archives" (kyp6f-nwaxw): stat /home/yunohost.backup/archives/.stfolder: permission denied
```
Can you please tell me what permissions I need to change exactly?
THANKS 🙂

I’ve try to add the user `syncthing` to the group `multimedia`, with little hope, but no difference.
I think I could add the user `syncthing` to the group `root`, but it does not seems right.
I’ll wait for your feedback before breaking anything.

Solved!
```auto
setfacl -Rm user:syncthing:rwx /home/yunohost.multimedia/thomas
```

Well, it’s not working after all.
- Syncthing can r/w on the Multimedia folder
- But now Nextcloud can not w on the folder creating by Syncthing…
When Syncthing create a folder:
```auto
# file: FolderCreatedBySyncthing
# owner: syncthing
# group: syncthing
```
So Nextcloud can’t write in it.
BUT this folder is also:
```auto
# file: FolderCreatedBySyncthing
# owner: syncthing
# group: syncthing
user::rwx
user:syncthing:rwx
user:nextcloud:rwx
user:www-data:rwx
```
So why Nextcloud can’t r/w ?
This is sooo difficult! But I will make it, sometime.
Thanks!

Have you found a solution to the problem?
I’m facing the exact same problem.

Sorry but no. I gave up using Syncthing. But I never really learned Linux permissions and I should. Nevertheless this is really not user-friendly.

I have found the solution. In your case it would be something like this
`setfacl -Rmb g:groupName:rwX,d:g:groupName:rwX,u:userName:rwX,d:u:userName:rwX /home/yunohost.multimedia/thomas`
But it’s unfortunate that you gave up using Syncthing I’m enjoing it by now. Yeah I give you the point that it takes somtime to get used to it.
And another hint for you: I created an extra group on the server just for folders that mulitple users have read/write access to it.

Hi @Jan.DEV-CORPS ,
Have you been able to enjoy syncthing with no problem since then?
I am trying to use the /home/yunohost.multimedia/share folder to create a shared file zone that is shared among the users.
I am very new to the ACL file permissions, so I looked at the man page to understand better.
So here where I ended up:
```auto
$ id syncthing
uid=993(syncthing) gid=993(syncthing) groups=993(syncthing)
$ sudo setfacl -Rmb g:syncthing:rwX,d:g:syncthing:rwX,u:syncthing:rwX,d:u:syncthing:rwX /home/yunohost.multimedia/share/
setfacl: Option -m: Invalid argument near character
$ sudo setfacl -Rb g:syncthing:rwX,d:g:syncthing:rwX,u:syncthing:rwX,d:u:syncthing:rwX /home/yunohost.multimedia/share/
setfacl: g:syncthing:rwX,d:g:syncthing:rwX,u:syncthing:rwX,d:u:syncthing:rwX: No such file or directory
```
I don’t see any particular change int he behavior, any help would be very welcome.

I am not sure what I have done is the proper way of doing it, but here is what I found to be functional.
The basic idea is to adapt the group members to allow the modifications by nextcloud, syncthing, and later any other program of file sharing.
```auto
$ sudo nano /etc/group
```
add to multimedia:x:1000:nextcloud,nextcloud\_\_2
```auto
,syncthing,users,www-data
```
Save (Ctrl+o), exit (Ctrl+x), then use
```auto
$ sudo chown -R www-data:multimedia /home/yunohost.multimedia/share
```
This made the job for me, then you have your shared files in this folder for all users to use.

Hi @mateMatt @isidoreisou @RaspYuno @gabjy !
I think I found a solution. It worked for me.
Connect to the server in command line (CLI) : [SSH and command line | Yunohost Documentation](https://yunohost.org/en/ssh)
Apply those commands (change the path according to your needs) :
```auto
sudo setfacl -R -m u:syncthing:rwX /home/yunohost.backup/archives
sudo setfacl -R -m d:u:syncthing:rwX /home/yunohost.backup/archives
sudo setfacl -R -m u:syncthing:rwX /home/yunohost.multimedia/admin/eBook
sudo setfacl -R -m d:u:syncthing:rwX /home/yunohost.multimedia/admin/eBook
```
Verify that the permissions were changed with commands below :
```auto
getfacl /home/yunohost.multimedia/admin/eBook
getfacl: Removing leading '/' from absolute path names
# file: home/yunohost.multimedia/admin/eBook
# owner: admin
# group: root
user::rwx
user:syncthing:rwx
group::rwx
group:multimedia:rwx
mask::rwx
other::r-x
default:user::rwx
default:user:syncthing:rwx
default:group::rwx
default:group:multimedia:rwx
default:mask::rwx
default:other::r-x
getfacl /home/yunohost.backup/archives
getfacl: Removing leading '/' from absolute path names
# file: home/yunohost.backup/archives
# owner: root
# group: admins
user::rwx
user:syncthing:rwx
group::rwx
mask::rwx
other::---
default:user::rwx
default:user:syncthing:rwx
default:group::rwx
default:mask::rwx
default:other::---
```
Then to allow syncthing to traverse these directories without altering existing permissions, you can add execute permissions specifically for the syncthing user using ACLs.
```auto
For /home/yunohost.backup:
sudo setfacl -m u:syncthing:x /home/yunohost.backup
For /home/yunohost.multimedia:
sudo setfacl -m u:syncthing:x /home/yunohost.multimedia
For /home/yunohost.multimedia/admin:
sudo setfacl -m u:syncthing:x /home/yunohost.multimedia/admin
```
