What would be a valid rsync command to connect to the speakup rsync server on that system? I used rsync -czvt anonymous at mirror.services.wisc.edu:/mirrors/linux/distributions/speakup/disks/debian/sarge/*.img . and got back a password prompt once their dsa fingerprint had been added to my system and supplying my email address just got me disconnected from the system as an invalid login.
