Reproducible. Appears to be a server side issue since the native client works fine against another SSH server. I'll try to take a look at the code tonight. |

This is slightly related, it doesn't hang but it will error without any info when trying to scp a file that doesn't exist on the remote #1284. |

- Changed fileio_fdopen() to simply return the file descriptor for non-disk file types. - Addresses issue where an error message in SCP (server side) was not being returned to the pipe which causes the process to hang. Resolves: PowerShell/Win32-OpenSSH#1345

What is failing
I am using openssh server for windows version 7.9.0.0 on Windows Server 2016. I am using it for scp and it works if i am uploading files to existing directories. If i will specify target directory not existing on my Windows Server then scp command get stuck and hangs forever.
