The client has not changed at all and worked before, I have many clients
that were working, now all stopped.  So I think it is on the server side.

  Bug in your .bashrc script, perhaps?  I forget the exact details (see man
page for full info), but some of the startup scripts are always run by the
shell firing up, but some are only run when you open an interactive login
shell.

  Try "ssh -v -v -v -v -v myhost" and see if the debugging info sheds any
light on the situation.



    cheers,
