The syntax is wrong:
- ssh -l is not need as rsync will use the user in the url:
rsync -av --rsh="ssh" *.* sshuser at host.com::module
- the ::module does not work is you're using rsync with ssh, aka using ssh as
pipe and not port forwarding. In this way rsync start ssh and use it to start
the rsync on the remote host, all transfert are made using pipe. So this is
rsync options...| ssh user at remote rsync --server same_options...
The module syntaxe '::module' only apply is your calling a remote rsync
listening on its port.
The correct syntaxe is:
rsync -av --rsh="ssh" *.* sshuser at host.com:/full_path
