openssh bugs - Oct 2003 - [Bug 739] A .cshrc that gives output causes sftp-server to reject sftp

http://bugzilla.mindrot.org/show_bug.cgi?id=739

           Summary: A .cshrc that gives output causes sftp-server to reject
                    sftp
           Product: Portable OpenSSH
           Version: 3.6.1p2
          Platform: Sparc
        OS/Version: Solaris
            Status: NEW
          Severity: minor
          Priority: P2
         Component: sftp-server
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: awkay69 at yahoo.com


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.

------- Additional Comments From djm at mindrot.org  2003-10-09 07:29 -------
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.
