Hello, I would like to create a folder on the FTP site to racine (root). Where there ssl, tmp, web ... Off SSH (in sudo or not) or FTP : "Permission denied".
You can't create folders on that level by FTP, FTP users are allowed to create folders inside the web folder and in private folder. If you want to create a folder on the root level, then do it as root user on the shell, first remove the immutable attribute from root folder, then create your new folder and afterward add the immute attribute again.
