Well, the 502 Illegal PORT Command error is obviously holding up the data-connection portion of the FTP session.
Your script is telling the server to send data from its FTP data-port (20 I assume) to your client's TCP port 53155.

FYI, the Syntax of the PORT command: h1, h2, h3, h4, p1, p2. EG: Calculation of the local socket-port is done like this:
p1*256+p2 = (207*256)+163 = 53155.

It could be a privileged/restricted ports issue -- Though that would give a 'permission denied' error (I would have thought).

For the record, 99% of all FTP data-connections are NAT/Firewall/socket-binding issues. Heh.

You didn't state whether you were *actually* able to upload/download successfully via your system ftp program either.

Google is good for FTP connection flow-charts etc...
