Description Tony Kay 2003-10-09 05:58:23 AEST 
Including:

echo -n "message"

in .cshrc (login shell set to csh) causes Linux, Solaris, and Windows sftp
clients to be rejected with the error message "Received message too long
1835365235". 

Of course, you could say that having output produced from an rc file is not
really a standard (or even desirable) practice, but that is neither here nor there.

You are correct: shell initialisation scripts shouldn't produce output. Put it
in .login.

This has been documented at http://www.openssh.com/faq.html#2.9 for over three
years.
