We're setting up an FTP server on Ubuntu 12. We need to create individual directories for clients and allow only certain users to access these directories. We also have an internal user group that has access to the top-level directory which contains all of our client directories.
I've looked at this option (link below) but I'm concerned that it just allows new users to access their own home folders, which is not of interest to us. We need to set rights and permissions for users and groups along the same lines as a Windows server. We're fine with command line and conf files, we don't need a GUI. We just need a clear path to the goal.
We do have the server running and local users can get access of sorts over sftp using FTP client software. Just need to sort out folder access.
How do we set up users, and then specify who gets access to what? Is there a step-by-step guide out there?
