Sounds like a problem with the command file (/tmp/ftp.$$). Post
that. From the "Not connected" errors I'm guessing it's a problem
with establishing user credentials. Are you able to FTP interactively
to the host from this box?

BTW if this script is designed to run in a particular context I'd
use .netrc files to contain the user name and password instead of
echoing them in the script. It's somewhat more secure, makes the
password easier to change, and simplifies your script.

Better yet is SCP, but you didn't ask about that.
