	Unix systems provide the chroot command which allows you to reset the / of the user to some directory in the filesystem hierarchy, where they cannot access "higher-up" files and directories.

	However in your case, it would appropriate to provide a virtual chroot implemented by the remote shell service. sftp can be easily configured to restrict a local user to a specific subset of the filesystem.

	hence in your case, you want to chroot let's say, user foo user into the /var/www/vhosts/ directory.

	You can set a chroot directory for your user to confine them to the subdirectory /var/www/vhosts/ like so in /etc/ssh/sshd_config;

	Create user foo with password
