The users for vsftpd are not chrooted, as I need them to have access to some shared folders. All users have their home directories in /ftp-data/<username>. Currently users can cd to other directories in /ftp-data. This is desired as there are shared resources there. However, how can I prevent the users from moving above /ftp-data to /?
