The post works, but it has a typo in it. The first rsync command should also have . as last parameter. Otherwise it downloads into /data/data (and full 6gb too).
If it doesnt work for you too, try this:
rsync -rtzv --progress --stats www.ryzom.com::ryzom/data .
rsync -rtzv --progress --stats www.ryzom.com::ryzom/client_default.cfg .
If it doesnt work for you too, try this:
rsync -rtzv --progress --stats www.ryzom.com::ryzom/data .
rsync -rtzv --progress --stats www.ryzom.com::ryzom/client_default.cfg .
