How can I make the user see nothing but /home/%username%?
usually in the desktop version of the OS, if you sit through the GUI, then only the user's working directory is displayed, and in the Server version, if you create a regular user and log in via ssh, it sees all directories and can read. Question: how can I make the user see nothing but /home/%username% when logging in via ssh?

Answer 1

If only for ssh, then you can decide at the ssh server level.
Write a line in sshd.conf
ChrootDirectory %h

Answer 2

chroot

Answer 3

I am using lhell. Not only the directory limits, but also the set of allowed commands.
