Hang / crash when powershell is executed from cmd via ssh (Windows 10 Pro)

Dears

I have on my remote Win 10 SSH installed follow instruction below:

https://github.com/PowerShell/Win32-OpenSSH/wiki/Install-Win32-OpenSSH

Connection to cmd works perfectly but after powershell is executed (from cmd) then connection looks like below (no commands can be executed - looks like no response from remote cmd).

Is this a bug? Please give me some hints / or please support me somehow.

Thank you and best regards.

like @manojampalam said in this issue, you can expect a better working solution end of May

[manojampalam]

Try the following:
Powershell -File -

That's telling Powershell to redirect its IO streams through std IO.

This is explained in https://github.com/PowerShell/Win32-OpenSSH/wiki/ssh.exe-examples

Thank you. Now it works: http://filmy.elektroda.net/48_1458924598.mp4

Only one question mark: why 'new line' (enter) works so oddly ?

[manojampalam]

the 'new line' should work better with the latest version. I put in a work around for now.

I had issues when execution PowerShell scripts from a .bat script that I started via a SSH session.
I've stepped onto this GH issue but in my case I wanted to run PowerShell scripts, not PowerShell interactive console.

Steps:

1. I open an SSH session to a Windows 7 workstation
2. I type the following command: C:\foobar\install.bat
3. install.bat script hangs in the middle of it's execution

Files

install.bat:

@echo off
echo Starting
cmd.exe /C powershell.exe -File "file1.ps1"
echo Done with file1
cmd.exe /C powershell.exe -File "file2.ps1"
echo Done with file2

file1.ps1:

Write-Host "EOF file1"

file2.ps1:

Write-Host "EOF file2"

Script would only print:

install.bat
           Starting
EOF file1
         _

And hangs. I had to press [Enter] for the file2.ps1 to run:

install.bat
           Starting
EOF file1

Done with file1
EOF file2
         _

And once more for the install.bat to end:

install.bat
           Starting
EOF file1

Done with file1
EOF file2

Done with file2

In my real use case, the stuff the file1.ps1 was doing (calling external binaries) made the "[Enter]-trick" not working (I had to kill the Powershell process).

My solution:

Use the -InputFormat None powershell.exe's option:

install.bat:

@echo off
echo Starting
cmd.exe /C powershell.exe -InputFormat None -File "file1.ps1"
echo Done with file1
cmd.exe /C powershell.exe -InputFormat None -File "file2.ps1"
echo Done with file2

Outputs:

install.bat
           Starting
EOF file1
         Done with file1
EOF file2
         Done with file2

Let's hope this help someone.
