Why do I get "Requested download is not authorized for use with this tracker"?

[Rick Thomas <rbthomas@pobox.com>]

I went to cdimage.debian.org and downloaded
http://cdimage.debian.org/cdimage/release/6.0.1/i386/bt-dvd/debian-6.0.1-i386-DVD-1.iso.torrent

Then tried to use it to download using Transmission (though I've tried  
other BT clients and had the same result).

I got the error message "Requested download is not authorized for use  
with this tracker".

What can I do to fix that?

I'm behind a NAT, if that matters -- though I've tried it from a  
machine with a "real" (i.e. world routable) IP address, and gotten the  
same results.

I've googled for that message, and looked thru the debian-user  
archives.  It pops up from time to time and I've never seen anybody  
say it's been fixed.

Has *anybody*, *ever*, succeeded in downloading a Debian DVD via  
bittorrent?

Thanks!

Rick
