Don't want to seem simple-minded, but does your interactive FTP client work
from the same machine you are running the Python script on? The error
message seems pretty unequivocal: the FTP server isn't prepared to accept
your request.

Given that you're using private IP addresses, maybe there's a firewall
component between your machine and the server that's rejectong your FTP
connection?

Otherwise, replace your host address with some known-accessible public host
and see what gives.
