The rrsync is a perl script that limits the user to only running authorized
rsync commands, including restricting options, optionally making it
read-only, optionally restricting directories, etc.  It's similar to rssh,
but only supports rsync.

The problem you're encountering with rssh is a very old one where it was
rejecting the use of -e combined with --server, which is not correct (the
correct method is to reject any rsync command that doesn't have --server as
the first option, and then no checking of the -e option is needed). This
was pointed out to them years ago, and was fixed in various debian/red
hat/etc packaged versions of rssh.  If you don't have a fixed version, you
can find some fixed source code via those source packages. Or choose to
switch to using the rrsync script.
