could it be that your US and Mexico network does not allow inbound
TCP connections from the Italy system? FTP uses a separate connection
for control (commands like mkdir, cd, pwd, etc) and data transfer (dir,
get, put). By default, the data connection is opened from the remote
to the local system. This seems to be the part that fails in your case.
Try using passive mode, if your FTP version allows it. This would
cause the data connection also to be opened from the local (US) to
the remote (Italy) system, and might work better.
As far as I recall, the FTP banner lines have a comment to say whether
passive mode is supported by the client and by the server. Before doing
a PUT or GET command, you would then use the PASSIVE command (try HELP
PASSIVE at the ftp prompt).
Not sure about DSCOPY, but maybe it also uses separate control and data
connections. Maybe it even does this based on the file size, which would
explain the strange size-dependency that you observed.
Lars.
