Windows – Passwordless ssh from Windows to Linux to run scripts from command prompt

Anyway, this guy shows exactly how to do it:

ftp -s:script.txt ftp.server.com

and the contents of script.txt could be:

your_username
your_password
bin
cd /files
put file.zip
bye

where the first 2 lines of the file specify the username and password used for authentication.

I've spent hours pounding on this very problem and it eventually came down to two viable options (there are a lot of non-viable options out there):

1. Build a Windows box with an IIS service hosting a WebAPI that is both domained and set up in such a way that WinRM sessions from it will work.
2. Cygwin

With the second option you're stuck fighting your way through the the GNU/Posix abstraction layer to get at the actual windows bits. Which does restrict what you're able to do with it.

The first option pretty much builds a web-based abstraction layer you write yourself on top of your full native-stack Windows install. If you're willing to put in the work, the Linux master-server only has to do a bunch of curl calls to do what needs doing. This works best when scripts are fire-and-forget though, as building a call-back system is a lot more effort.
