Yes, because you are connecting via the tunnel to the ssh server on C

Yes, because you are trying to connect to an rsync server
(NOT ssh server!) and there isn't an rsync server running on
localhost... (873 isn't forwarded either).

That's because you're telling rsync to connect to the ssh server, for
some reason...

It's your thinking...
If you don't want to connect to an rsync server, don't use "host::"
Use a single : to connect via ssh (assuming a recent rsync that defaults
to ssh instead of rsh...)
