Q.  How can I restrict an account to ftp only?

A.  Make file /usr/local/bin/ftponly that contains:

#!/bin/sh
echo "Only FTP access is allowed with this account."
exit 0

and make it executable:

chmod a+x /usr/local/bin/ftponly

Then make it the user's shell:

chsh -s /usr/local/bin/ftponly <user>

Test it:
Try to login to this account with ssh, you should be denied

Alternately, some ftp server all virtual users.  ie users who aren't Linux
users.
