[lug] How to set up a private FTP account for a user?

[Bill Thoen]

I've got a need to provide upload/download FTP service for one of my 
clients, and I'm not sure how to go about it. I've got a RedHat FC2 
server set up with vsftpd, and I have set up a public FTP download 
service on it that works very well. However, I would like to allow 
specific users passworded access to some private areas and allow them to 
upload and download files via FTP. I don't want to allow them program 
execution, email, and other privileges that would go along with a normal 
new user account.

I've searched Google and and the docs and man pages, but I'm afraid I 
don't know exactly what I'm looking for. Most of these resources simply 
describe settings, but they don't say when and how you would use them to 
do what I want to do. (Or maybe I'm just too thick to recognize the 
obvious.)

I'm also aware that FTP is not the most secure transfer protocol because 
passwords are sent in the clear, but I'd like to learn how to do this 
with vsftp anyway and worry about additional applications later (One 
thing a time.)

Can anyone suggest a HOWTO or a README or maybe just tell me how to do this?

Thanks,
