As far as I can tell I tried to enable passive mode before transferring 
any files.  In the example I posted I called "set passive on" before I 
called "open ..." - I also tired setting passive on in the preferences 
file - which should have ensured that passive was on as soon as the 
process started.  Both of these fail for me.

I can't use wget - because I want to put files... I can use the classic 
"ftp" program (which works fine is passive mode) - however I dislike the 
user interface... ncftp worked fine for me in the past...

I've discovered that ncftp keeps "trace" files - this is what it shows
