Re: [ros-dev] GSOC 2016 - SSH Service Project

[Mohamed MEDIOUNI]

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, ...)

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%20and%20Design%20Details)
 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,
Anchit Jain

Re: [ros-dev] GSOC 2016 - SSH Service Project

[Zachary Gorden]

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.

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 :
