Almost connected, but not quite.

From:	David A. Cobb
Subject:	Almost connected, but not quite.

Background: I run  MS Win98se, Cygwin-<latest>,
Xemacs-i686-pc-Cygwin32-21.1.13, OpenSSH [from Cygwin download].

*Pardon the cross-posting, I don't know whose piece of the puzzle I
missed*

I am trying to make a secure tunnel to a cvs server.
I greatly prefer to do everything in Xemacs (shell-mode for commands),
it is nice to be able to page up and down over my output & such.  Among
many many other good things.

So I execute Xemacs via. SSH-AGENT:
<blockquote>
    $ SSH-AGENT Xemacs -f shell
</blockquote>
and the first thing in Shell I do the SSH-ADD so my identity file is
known.

Everything I know about the server is in my ~/.ssh/config file.  That
lets me avoid trying to figure how to get the params right for Xemacs
SSH command, also to avoid retyping the same thing.  [It is not
attached, for obvious security reasons.]

First I tried using Xemacs M-x ssh.  It connected just fine and I had
lots of debug printout to prove it.  Then I set CVS_RSH to
"/usr/bin/ssh" and did CVS ... :ext:
that worked nicely also up to a point.  When I saw I was getting the SSH
debug output I did a $ ps and saw I now had two of them.  I shut the
whole thing down and started again.

Second try I let CVS start SSH, as it should do.  The /attached/ session
log shows that it went fine until the SSH passed the "cvs server"
command up to its counterpart.  Then nothing!

Please advise [ in other words HELP! ]
