sshd is working for clients but not for sftp #1489

Closed mcajkovs closed 4 years ago

mcajkovs commented 5 years ago

My OS is windows 10 Home and I've successfully set up sshd server for clients but not for sftp.

I've followed this wiki to set up SSH server https://github.com/PowerShell/Win32-OpenSSH/wiki/Install-Win32-OpenSSH

Steps I've taken:

  1. downloaded latest release https://github.com/PowerShell/Win32-OpenSSH/releases/download/v8.0.0.0p1-Beta/OpenSSH-Win64.zip and extracted it in c:\Program Files\OpenSSH
  2. next steps were preformed either in admin mode cmd.exe or admin mode powershell.exe
PS C:\Program Files\OpenSSH> Get-Service ssh*

Status   Name               DisplayName
------   ----               -----------
Stopped  SshdBroker         SshdBroker

PS C:\Program Files\OpenSSH> netstat -ano | findstr :22
  TCP    192.168.195.1:64929    192.168.195.130:22     ESTABLISHED     22508

CMD c:\Program Files\OpenSSH>powershell.exe -ExecutionPolicy Bypass -File install-sshd.ps1
[SC] SetServiceObjectSecurity SUCCESS
[SC] ChangeServiceConfig2 SUCCESS
[SC] ChangeServiceConfig2 SUCCESS
sshd and ssh-agent services successfully installed

PS C:\Program Files\OpenSSH> Remove-NetFirewallRule -DisplayName 'OpenSSH Server (sshd)'
PS C:\Program Files\OpenSSH> New-NetFirewallRule -Name sshd -DisplayName 'OpenSSH Server (sshd)' -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22
PS C:\Program Files\OpenSSH> netsh advfirewall firewall add rule name=sshd dir=in action=allow protocol=TCP localport=22
CMD c:\Program Files\OpenSSH>rm -rfd %programdata%\ssh

PS C:\Program Files\OpenSSH> net start sshd
The OpenSSH SSH Server service is starting..
The OpenSSH SSH Server service was started successfully.

  1. added following lines to %programdata%\ssh\sshd_config

    SyslogFacility LOCAL0
LogLevel DEBUG3
Subsystem   sftp    C:/Program Files/OpenSSH/sftp-server.exe

  2. restarted ssh

    PS C:\Program Files\OpenSSH> net stop sshd
PS C:\Program Files\OpenSSH> net start sshd

  3. connect from another machine (in my case guest virtual linux) via ssh -vvv 'marek'@192.168.195.1 works but sftp (also winscp) fails:

> sftp -vvv 'marek'@192.168.195.1
