Win2k Scheduler not able to execute rsync over SSH

Hi All:

This seems to work for my W2K environment.

1) CYGWIN has a definite problem w/ terminating sessions.
   If you look on various rsync forums, CYGWIN isn't closing
   some of its loose-ends properly.

2) I have rsync and passwordless authentication working under W2K.
   Within Task Scheduler I run a rsync .bat file, I also specify
   that the TS terminates the rsync job (which it must do because
   of 1) within 1 hrs time. Inside of the .BAT file, I need to set
   up the following MS-DOS environment variables, for the W2K
   account 'rsync':

      @set HOME=E:\home\rsync
      @set HOMEPATH=E:\home\rsync
      @set USERNAME=rsync

   As well as:


   This will allow your Admin account to set up scheduled tasks
   that can run as a non-admin account.

3) I also test ssh beforehand to make sure it works. I had problems
   talking to servers that use SSH protocl 1. Under W2K, set up a 
   test ssh script something like:

      @set HOME=E:\home\rsync
      @set HOMEPATH=E:\home\rsync
      @set USERNAME=rsync
      ssh -p 2245 -1 rsync at someserver-A

4) Because of 3) the rsync script looks like this:

      @set HOME=E:\home\rsync
      @set HOMEPATH=E:\home\rsync
      @set USERNAME=rsync
      rsync -av -e "ssh -p 2245 -1" rsync at sch1p115:/somepath-A/

   No need to use the '-i' option to force it to use an alternate key
   The excludes option is working great.

5) On some servers, the rsync modules feature isn't working (I dunno
   Also my ~/.ssh/known_hosts file is sometimes at odds w/ its
counterpart file 
   on the remote, delete remote entry within your local file and do
another .ssh
   connect to regenerate known_hosts entry for the remote.

6) My W2K server is *NOT* an SSH server, that's a whole nuther topic. It
   is an ssh & rsync client.

Most likely the problem is that the Task Scheduler is executing your
batch file under a different user context than the one in which you are
executing it from the command line.  Remember that cygwin's openssh
looks for public keys under the user profile for whichever user context
is currently relevant - so if for instance Task Scheduler is operating
as LocalSystem and you published your SSH keys as Administrator, you
will have no joy in your automated SSH task.

Hope that helped.
