Hello everyone,
I am Anchit Jain, Computer Science undergraduate from BITS PILANI, India.
I am interested in pursuing SSH Service project.
I have some experience in Socket Programming and Network Protocol development
in C. Some of my work could be seen at [https://github.com/anchitjain1234](htt
ps://link.nylas.com/link/ezhvubksgc7dhi29sglp2mpvq/7af2e7b30ed04821b97b5daf…
9e7a5/0?redirect=https%3A%2F%2Fgithub.com%2Fanchitjain1234).
In past, I have implemented some basic network services like TFTP protocol and
some minor part of FTP client.
Regarding the project :- Would this project require a new SSH Server to be
written from scratch or to be build upon some existing codebase like Apache
Mina etc.?
I would request potential mentors to guide me for the same.
Thanks,
Anchit Jain

Any SSH server developed for ReactOS would need to be written in C/C++ and
be compilable by both GCC and VC++. So while the expectation is that a
developer would likely need to pull a SSH library from an existing source
such as OpenSSH, the server itself will almost certainly need to be written
from scratch if only because there does not exist as far as I am aware of a
fully open source SSH server that runs natively on Windows without hauling
around the likes of cygwin. Apache Mina is written in Java and therefore
would be inappropriate as a starting base for the SSH server project.

Why do we want an SSH server in the source?
If someone wants to run an SSH server, they can download and install one as they would do
on Windows.

Perhaps have a look at <https://github.com/PowerShell/Win32-OpenSSH>
which is Microsoft's effort at porting OpenSSH so that it can work with
PowerShell. (They are reusing what NoMachine had done before them.)
AFAIK they culled most of the OpenSSL functions in order to replace it
with Windows crypto, but since the argument of that being proprietary
would not hold in ReactOS, you could possibly use the ReactOS crypto
straight.
Otherwise, from what I know, you can re-enable the use of OpenSSL in it.

Thank you so much for explaining things related to the project.
I looked into Win32-OpenSSH and in design details
(https://github.com/PowerShell/Win32-OpenSSH/wiki/About%20Win32%20OpenSSH%20…)
they have explained many of the things that they replaced from OpenBSD systems and how
they have worked around that.
Regarding this, yesterday I discussed on IRC where I came to know that React OS is
compatible with Windows Server 2003 so fork of Win32-OpenSSH theoretically might work
directly on React OS or might need some minor changes where Win 7+ API would have been
used.
So this project mainly reduces to make the fork of Win32-OpenSSH compatible with React OS.
Whether taking this port of SSH to windows can be seen as ok for the GSOC, or not?
If not, what other things could be added to make it OK for GSOC?
Thanks,

Simply getting the MS port of openssh working on ReactOS would not be
sufficient, for a variety of reasons. The biggest is that such a
project does not constitute a significant amount of work to warrant
the project using one of its gsoc slots for it. Next, MS' openssh port
is not a pure C/C++ build, it apparently still needs to make use of
perl in the build process. That is not acceptable from the team's
perspective, any code that goes into our tree, even as an import,
needs to be buildable with nothing more than a c/c++ compiler, and
cmake files for generation of ninja/make/msbuild files. We will not
accept another buildchain dependency, especially not something as
heavy as perl.
To be frank, the project considers this particular project as fairly
low in priority. If you want to apply for one of our gsoc slots with
this project, you will need to come up with a very, very good proposal
to convince us it warrants a slot.

There is no PowerShell in ReactOS yet, nor any kind of a .NET Framework
subset. While it doesn't matter for the SSH port, it can be highlighted.
In which *areas* do you want to apply for GSoC?
(networking, services, system, drivers, ...)

Thanks for your insight.
I am interested in applying for networking related projects.
So finally I don't think SSH service project would be considered a good project as its
really low on priority therefore, I would choose some other topic and would research on
it.

Hi Zachary,
Le 02/03/2016 17:58, Zachary Gorden a écrit :
actually there is a project at microsoft for porting openssh on windows
as a native process. I think it come from the NX/Nomachine code base:
https://github.com/PowerShell/Win32-OpenSSH
It does compile and install without cygwin are a prerequisite, however
it is not yet production ready.
About the next post of Ged, there seems to be a plan for MS to add a ssh
server in their distribution :
