    I am running the SSH Secure Shell (TM) client and trying to connect to my
    Solaris 9 box (Which runs Sun_ssh_1.0) and I get the message
             'Server responded "Key Exchange Failed.". Key exchange with the
    remote host failed. This can happen for example if the remote computer does
    not support the selected algorithms.'

    When I use PuTTY, I have no problems.

    Any thoughts?
