Now this is one great command line, thanks! :-)

The output of
curl -4 --show-error --include --head ftp://ftp.cs.uni-frankfurt.de/pub/Mirrors/knoppix 
curl: (19) Given file does not exist
is somewhat confusing though, since the mirror in Frankfurt is OK and all
Knoppix files exist. Maybe curl tries to download a certain file instead
of just checking for the directory index?

rsync can be tested easily by

rsync rsync-url
or
rsync host::

without a destination file or target directory.
