ftp and telnet problem

["kapil" <kapilcool yahoo com>]

I want to allow all of my users to ftp into my server from remote location
but deny some of the users to telnet to my server. If I will change the
shell of any of the user from "/bin/bash" to "/bin/false" or
"/usr/bin/passwd" then both ftp as well as tenet will not work. Is there any
way by which I can remove telnet access for specific user and allow ftp
access for the same user?

Thank you
