To jail / chroot users (not the VsFtpd service), there are three choices. Search for “chroot_local_users” on the file and consider one of the following:
vi /etc/vsftpd.conf
and modify as:
chroot_local_user=YES chroot_list_enable=NO
vi /etc/vsftpd.conf
and modify as:
chroot_local_user=NO chroot_list_enable=YES
Create the file /etc/vsftpd.chroot_list with a list of the jailed users.
vi /etc/vsftpd.conf
and modify as:
chroot_local_user=YES chroot_list_enable=YES
Create the file /etc/vsftpd.chroot_list with a list of the “free” users.
