SMB writes wrong permissions (SOLVED)

[froland80]

I log into my unraid from windows or mac with a specific user name. That works all fine and I can upload and change files.

However, turns out the SMB uploaded files are owned by that user and not accessible by other users even though the share they are in is a public, non-secure one.

I can fix this with the "Safe new perms" tool, but it's a recurring issue.

 

What do I need to change to maintain proper file permissions (nobody/users) when uploading via SMB?

After a bit more digging found several related posts (after understanding that this is about forcing a user over SMB):

• Exactly my problem

Solution is to add the following lines to your /boot/config/smb-extra.conf

 

[Global]

  force create mode = 0666

  force directory mode = 0777

  force user = nobody

  force group = users

  create mask = 0666

 

Marking as solved.

P.S. As noted in some of the other posts, would be nice to have a better way of handling this in the unraid UI.

This shouldn't really need to be 'handled' at all.  Unraid forces the use of nobody.users and I can see why TBH.  But if they're going to do that, they should really default all the built in writing to their chosen permissions format.  File sharing has never been the strong suit of unraid unfortunately, but with a bit of tweaking it can work OK.

I'm still having a slight issue with this -> I've applied the changes above

 

Something continues to change my Pictures SMB folder from 0777 to 0770. Is there somehow to create a new user that can't modify folder permissions?

Do you have a Docker or VM that has access to this folder?  The reason that I mention this is that either of these can write directly to the array bypassing SMB.

You can paste this in [server address]/Settings/SMB, which will put it in the exact same file.
