Run Windows application via ssh

Run Windows application via ssh

[Mauro Migliorati]

Hello,

I installed Cygwin on a machine with Windows XP and started the service sshd.
I would like to connect from another machine (client) via ssh, run a Windows 
application on the server and view the window on the client. I do not want to 
use vnc, I just want to run a single application, not the desktop of the 
server that is used by another user.

I manage to connect via ssh but, when I try to open an application, like 
notepad, it does not appear on the client screen.

Thank you for any hint,
-- 
               Mauro

Specify the '--interactive' flag to 'cygrunsrv' when you install 'sshd'.

This will only pop up notepad (or any other windowed application) on the
*server's* desktop.  What the OP wants is forwarding of individual
graphical apps over ssh, and this can't be done with Windows apps.
Perhaps a remote desktop solution of some sort will work.

Right, sorry.  I don't know how I missed the "view the window on the client"
part.

This will not work unless the application is an X Windows program. 
Native windows apps cannot be used remotely with ssh, because they are
not network-aware.  This may be possible with remote desktop/terminal
server/etc, but it's outside the scope of Cygwin.  All that ssh can do
is forward a stream of bytes across the connection.  The application
must be designed to work in this manner, such as X11 apps.  Ssh cannot
work miracles.

Windows 2003 and sshd

[Stephen Treger]

Hello,

I had a RedHat box, the sole purpose was to be the intermediate between a 
secure host and public for moving data files in/out. Obviously this was 
done solely upon ssh (scp/sftp). For numerous reasons we decided to 
reconfigure as Windows 2003 Server with CygWin and openssh.

I took a XP workstation, loaded CygWin with the required openssh and 
openssl components, populated the passwd and group files from our AD using 
the -d options on mkpasswd and mkgroup respectively and then installed sshd 
as a service.

It was the coolest thing, I would ssh in as a user listed in the passwd 
file, but never having logged into the box before, and it automatically 
created a home directory and populated it with the skeleton files. First 
login produced some warnings, but after that the directory was set up 
properly and everything worked.

So I duplicate on the Windows 2003 box. Hmm, if I don't create the home 
directories manually users are instantly rejected. Some users out there 
claimed I must run a script (fixperms.sh) for it all to work properly and 
securely; I did and now am worse off than before. I get errors reprting no 
rights to the shell (though the user does have rx to the various shells).

So I thought I would start over with CygWin on the 2003 box, but when I 
deleted and reinstalled all the weird permissions still existed.

Anybody got a really good HOW-TO on this?
I need multiple users to have their own secure home directories, a couple 
of additional logins that are in a "admin" group and can control those 
directories. If I need to jail them, how do you do that under cygwin and is 
it feasible?

I suppose that was my point.  THe poster specifically didn't want to use
VNC, and using Remote Desktop or similar is really out of the scope of
Cygwin.  All cygwin and ssh know or care about is transporting a stream
of bytes over the network.  Alternatively put, those methods all work
equally well independently of ssh (ignoring the security issues) so it's
really not fair to say that ssh is contributing at all to those
solutions... The poster was asking "Make ssh do FOO" but the answer is
"ssh can't do FOO, but BAR can do FOO (optionially with ssh as the
transport.)"
