rsync: connection unexpectedly closed (0 bytes received so far) [Receiver] #1869

A possibly related question: how can one control in OpenSSH for Windows whether
That distinction between binary-transparent low-level I/O and cursor-control-oriented console I/O in Windows does not exist under Unix, and therefore I assume there must be some selection mechanism to tell OpenSSH for Windows, which of these to use. I have a suspicion that distinction may be involved in why people have problems using OpenSSH for Windows as a transport tunnel with Unix applications such as rsync, git and subversion, which all pass compressed binary files via stdio to the other side, i.e. are definitely not using SSH as any kind of console application (with UTF-8, ANSI codes and line feeds). Because the ConPTY route will translate/rewrite all ANSI control sequences and is therefore hardly suited as a binary-transparent channel for compressed file transfer, which will only work via Unix-style pipes to redirected stdin/stdout via low-level This is something that I never found well explained in the OpenSSH for Windows documentation, and as this distinction doesn't exist in Unix, the upstream OpenSSH documentation won't be able to help here either. |

Met the exact same problem. Using cmd also doesn't help. |
|
Does this |
|
It is still there with v9.2.2.0p1-Beta |
|
Use msys2's ssh.exe to transfer normally. Win32-OpenSSH here keeps reporting errors. rsync.exe -e E:/sdk/msys64/usr/bin/ssh.exe |
and others

Configure OpenSSH Server
Install cwRsync
Create

rsyncThis will fail.
I tried to troubleshoot this problem.
It shows:

Change to use cwRsync's
ssh.exeThis will okay!
Try to show ssh logs:
The result:
Terminal issue? please go through wiki
