[NTLUG:Discuss] only the user see its directory on ftp

[m m]

Hi all:
How do I set up 'only the user see its directory' while they doing ftp?
In order for apache to work (apache is pointing to /home/user/www), all the 
directories must to set read permission.
in this case, when a user use a _powerful_ ftp client, login as the user, 
and then he can change directory up to parent directory, all other user 
directories/files will be able to see.
Is there anyway to set the user only able to see it own directory/child 
directory and not allow to change to its parent directory (/home)?
I am using RedHat 6.2, 2,2,14 kernel. with iptable firewall running.
