I'm starting to wonder if my problem is based on my client running NAT.
I tried changing the line:
            headerlist = curl_slist_append(headerlist, "RETR " + file);
to
            headerlist = curl_slist_append(headerlist, "PASV");
            headerlist = curl_slist_append(headerlist, "RETR " + file);
But now I just get:
227 Entering Passive Mode (67,205,122,7,192,94).
And now it just sits there. How do I deal w/this?
