This seems to be a favorite thing to suggest/try lately.  I suppose
because it's a common debugging option on most Unix/Linux distributions.
But on Cygwin, just suggesting the above and leaving the rest to the
otherwise uninitiated is like helping someone out of a hole by handing
them a shovel and telling them too dig.  If you ever plan to run 'sshd'
as a service (as configuring using 'ssh-host-config' will do for you),
this will only work if you do the above as the user that will run the
service.  On XP, that's SYSTEM.  So you need to start a SYSTEM-owned
shell using AT before the above isn't just a recipe for more headaches.
See the email archives for details if you're not sure how to start a
SYSTEM-owned shell.  Or just stop and ask yourself why you need to know
how to do this (beyond intellectual curiousity of course! ;-) )  And of
course if you're starting 'sshd' using any configuration other than
the 'ssh-host-config' script, then you should really know what you're
doing, as I outlined in my response from yesterday:

<http://cygwin.com/ml/cygwin/2009-06/msg00175.html>

Since the OP is having difficulties with 'sshd' on Cygwin and is asking
for help here, I would surmise that he falls into the category of
the uninitiated in this instance.  So, my recommendations are to:

   1. Look at 'ssh-host-config' and note all the directories that it
      does "chown" on.
   2. Run 'ssh-host-config' to configure 'sshd'.  Take the defaults unless
      you have a very good reason not to.
   3. Check after the script completes that the ownerships of the directories
      found in (1) above are as 'ssh-host-config' set them.  On XP systems,
      the "$(run_service_as}" user is SYSTEM.

Following random guides found on the Internet to configure Cygwin's 'sshd'
is not supported by this list.  Reading the openssh readme in
'/usr/share/doc/Cygwin' is only supported documentation.  If you prefer to
use another source for your configuration information, please avail yourself
of any support/help from the site where you got this information.
