Thanks.
The "authorized_keys" file seems to be the point. However now my
questions are:
-- Should the "authorized_keys" file always have the same content as
that in the file "id_rsa.pub"? If so, why do I have to copy the file
to another name, while the file "id_rsa.pub" is readable to everyone?
-- If I have a ftp-only account (I don't even have a home directory,
can not even login the system via ssh -- only sftp or ftp is allowed),
how can I make my configurations as above? Do I have to seek for help
from the root? What if he can't build a commonly-shared
non-interactive configuration for that ftp-only user?
