Weird permissions for new created files and folders (SFTP)

Hi,

I know there is pam_umask that controls permissions for newly created files and folders. The default settings are active in /etc/login.defs (umask 022) and pam_umask is activated using the file /etc/pam.d/common-session.

Well, umask 022 effects, that new files have permissions of 644 and folders 755.

But something is weird there. When I connect via SFTP, new folders have a permission of 775 (umask 002) and new files the default 644 (umask 022).

Why do they have different permissions? Is there a way to configure different default permissions for files and folders? But I changed nothing of the default configuration and my .profile is untouched.

Any suggestions?

Hello,

What are you using to SFTP to the droplet? Many times they set their own permissions and so can change things away from the default. It almost sounds like this is the cause.

Have you also tried setting the same umask values in the /etc/profile file as well? If you are using BASH you may wish to add it to the /etc/bashrc file as well.

The /etc/profile and /etc/bashrc files can override defaults set in other locations in many case.
