The issue you are facing:
Everything is running fine with this one odd problem.
I have set up an External Storage to a local directory for a user pat
to house my todo.txt files. I was hoping to be able to access and modify this todo.txt file from other machines that are synced. However, something is not happy.
The local folder /home/pat/todo/
has these permissions:
drwxrwsr-x 3 pat www-data 4.0K Aug 1 10:24 todo/
Where www-data
is the apache user. Both www-data
and pat
are in the group www-data
.
The directory listing and file permissions are as follows:
-rw-r--r-- 1 pat www-data 162 Aug 1 10:23 todo.txt
Notice the group does not have +w
on the todo.txt file.
If I add g+w
on the todo.txt
file, I can write to the file locally, and the changes are synced to my clients. Everything looks peachy!
-rw-rw-r-- 1 pat www-data 162 Aug 1 10:23 todo.txt
The Problem
The problem comes when I edit the same file on a client. If I modify todo.txt
on a client, the file will sync. So far so good. But the permissions have now changed (on the server):
-rw-r--r-- 1 www-data www-data 238 Aug 1 10:39 todo.txt
This is not good.
How can I fix this, and why does www-data re-claim ownership of the file (and change the perms to remove group writing)?
My workflow/desire is to:
- have this local folder be accessible by the user
pat
on the server - share this folder as a local external storage where clients can access (r/w) the files
- and have the sync back to the server work. (for continued access by user
pat
there)
