I am running my SSH server on a Debian build of Linux. When I connect to the server, I get access to the whole laptop's files. when I log int the file location I get access to is: '/home/myuser', but I want to change it so, when you log in to the server, I want there to be multiple users and each user has their own folder they can access and edit. An example of the server's folder would be: '/home/myuser/serverfolder' and within '/home/myuser/serverfolder' there would be a folder for each user.
How can I do what I explained above?
