FTP Newbie Permissions Question

[MyNameIsTom]

Nice to meet you.
I'm new to Linux.

I'm running a server off of Fedora 7.
I'm FTPing with vsftpd.

I have the directory /var/www/sub.

I have the user1 who's home directory is /var/www/sub/user1.
I have the user2 who's home directory is /var/www/sub/user2.

Right now, no matter who I login as for FTP (except anonymous) I can access all folders on the server.
I only want user1 to be able to access /var/www/sub/user1 and user2 to only access /var/ww/sub/user2. I don't want them to have permissions to access any of the parent directories or any other folder on the server for that matter.

Check the owner and permissions of each directory with the commands:

ls -ld /var/www/sub/user1
ls -ld /var/www/sub/user2

Owner should be user1.user1 and user2.user2 respectively.
The permissions should be: drwx------
If they're not but something like drwxrwxrwx then this allows any user to access the directories.

Use these commands to fix the permissions:

chmod 700 /var/www/sub/user1
chmod 700 /var/www/sub/user2
