I'm having trouble with read/write permissions on my Samba server, how do I fix my smb.conf and file permissions to have a more unified access?

Samba has its own layer of access control for each share. There are two basic options

  • read only: by default every share is read-only, regardless of filesystem permissions,
  • writeable: in order to allow write access you should set writeable = Yes.

This should be enough to solve the problem. But if you'd like to learn more about Samba permissions, like how to set umask, enable guest account or control access for individual users/groups, then read the short tutorial on Samba permissions.

Problem is that my smb.conf isn't responding the same as the expected output... see my question update – Eric Fossum Mar 20 '11 at 22:49
Could you explain to me why my settings don't take affect till I restart? (Yes, I know about sudo /etc/init.d/samba4 restart) – Eric Fossum Mar 22 '11 at 5:17

Since you don't seem to need Active Directory integration, you're probably better off installing Samba 3 (in the "samba" package) rather than Samba 4, which has not been released yet.

"writeable = yes" is an alias for "read only = no" in Samba 3. The alias has been removed in Samba 4.

I just had same problem as OP. Samba config was set up correctly but still I could not write files.

My problem was that directory i wanted to share was created by root user so i had to chown that directory to my normal user and everything is working fine. I can create /delete and /modify files and folders now.
