FTP ?

Hi.
I have “2” RedHat 7.1 computers linked together via a hub. I have WU-FTP installed on one computer, “called server”. I have access to the server and all the files and folders via the client. The problem is the wu-ftp server is supposed to drop me into the ftp home directory, not the root directory of the server. Not Good. How can I limit the ftp user to the ftp home directory, usually called PUB. I cant find the information in my books.
Thanks Pat
