I'd like to assume that a) when I fail to provide a port to the ftp client,
it will use the default port, and b) if I fail to provide a port to
ftplib.FTP() it will use the default port, and c) in the same environment,
for the same user, that default port will be the same. 8-)

But I'll gladly stand corrected if that's an unwarranted assumption.

hehe. Yep. That's the actual string I type to cahnge directories on the
server. Tandems are Funky.

Thanks...I'm kinda new at this...

Not so much noise, as much as not yet relevant, but educational nonetheless.
My first step, before I start sniffing ports, is to fire up an ftp server on
my own machine, and try to connect to127.0.0.1. If that fails, well, you'll
be hearing about this again. Let's hope it doesn't come to that. That would
just be too freaky. 8-)
