Very Computer

I'd like to restrict guest user to seeing only its home directory during a ftp
session.

I've tried
chroot /home/guest /usr/bin/ftp
but it give me a
chroot: cannot execute /usr/bin/ftp: No such file or directory

Of course, it did check the ftp is there.

I've also tried to change the passwd file of guest to
guest:x:507:507::/home/guest./home/guest:/bin/bash

but instead of making the /home/guest as root directory, it default to the root.

I greatly appreciate any help.

Thanks.
