While i doubt the stty errors are the problem stty should
never be called from a .cshrc file. stty belongs in .login
where it will only be called for login shells.  .cshrc
should be as small as possible because it is run every time
you launch a shell (including scripts).  My recollection is
that stty should either be complaining "not a tty" or not at
all so the "invalid arguments" and is one more hint that
there is old stuff (from SunOS?) and the dot files should be
audited.

It is clear that things are not configured correctly for ssh
and csh.  I'd suggest while testing that you disable X11
forwarding (either -e "ssh -x" or set the RSYNC_RSH
variable). The fewer extraneous errors the easier to debug.

There have been some reports that the version of ssh
supplied by Sun has problems with rsync.  Those who have
reported this have found that openssh works fine.
