vsftp problem with user escaping directory

Hi there.

I've setup a user on a slackware box with VS FTP running on it.

This user has his regular home directory but in that home directory is a symbolic link that takes a user to /var/www/html/test/testdir
(I know it's not terribly secure but i cant avoid it for now)

The problem being that this user can "cd .." and get to /var/www/html/test . "cd .." again and he gets to /var/www/html.

This is somewhat worrying.

How can I prevent a user escaping his root directory structure and going above it?

open /etc/vsftpd/vsftpd.conf

and add a line into that

chroot_local_user=YES

and restart vsftpd .

chroot_local_user
              If  set to YES, local users will be placed in a chroot() jail in
              their home directory after  login. Changing to symobolic links
              will fail .
