From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Samba share writable to everyone, even if someone else created the files? (feddit.de)

I have a public SMB share mainly as a media dump. Everyone can read and write, without any auth - as intended. However, if I copy files via SSH (as a regular user, not the samba user), these files are of course owned by that user and thus not writable for the samba user - so I can't touch these files via SMB.

My config looks like this

[public]
  path = /path/to/samba/public
  guest ok = yes
  writeable = yes
  browseable = yes
  create mask = 0664
  directory mask = 0775
  force user = sambapub
  force group = users

I can fix the permissions by simply chown/chmod all files, but that's not really a solution.

Samba is a pipe of sorts... those settings only apply to files created using that pipe.

SSH is a different pipe, with different configuration. I think you need to modify the umask of the user connecting via ssh and/or add them to a samba group.

umask seems to only set the permissions, not the ownership. But ownership seems to be necessary to delete files.

... which is why you also need to join the samba group.

The user is in that group, but files are (by default) owned by the user (that is, the group of the same name as the user, I'm not sure, what the wording is).

However, at least it seems to currently work somewhat. I had to chown and umask the entire share, and then restart the machine. Maybe some dangling session interfered?
