Did I mess up my mailing list subscription?

[Leroy Tennison]

I subscribed to this list two days ago, didn't get any response.  I posted a message titled "ssh server immediately closing connection" on Sep 2 19:49:26 GMT 2020 which received questions as a response but I never got an email so I'm having to reply with a new post - I'm sorry, I don't know what else to do.  If I need to re-submit a subscription request please let me know.

I was asked:

1) Please detail the windows service configuration.

   $ cygrunsrv -V -Q cygsshd
      Service             : cygsshd
      Display name        : CYGWIN cygsshd
      Current State       : Running
      Controls Accepted   : Stop
      Command             : /usr/sbin/sshd -D
      stdin path          : /dev/null
      stdout path         : /var/log/cygsshd.log 
      stderr path         : /var/log/cygsshd.log
      Process Type        : Own Process
      Startup             : Automatic
      Dependencies        : tcpip
      Account             : LocalSystem

     Note: /var/log/cygsshd.log is zero length

      C:\Windows\system32>sc qc cygsshd
      [SC] QueryServiceConfig SUCCESS

      SERVICE_NAME: cygsshd
              TYPE               : 10  WIN32_OWN_PROCESS
              START_TYPE         : 2   AUTO_START
              ERROR_CONTROL      : 1   NORMAL
              BINARY_PATH_NAME   : D:\cygwin\bin\cygrunsrv.exe
              LOAD_ORDER_GROUP   :
              TAG                : 0
              DISPLAY_NAME       : CYGWIN cygsshd
              DEPENDENCIES       : tcpip
              SERVICE_START_NAME : LocalSystem

2) I see that you are running as cyg_server account. Please try as SYSTEM.
      I got the same result running as system (note LocalSystem above)

3) Please confirm the issue is the same in the windows event log

Checking the log for a service with both a Local System and cyg_server, the entries were identical in detail (abbreviated)

      The description for Event ID 0 from source sshd cannot be found.
      
Running as LocalSystem:
     [ UserID]  S-1-5-18
      sshd: PID 3103: fatal: seteuid 1050745: No such device or address
Running as cyg_server:
     [ UserID]  S-1-5-21-286763150-81293845-2154422431-1017
      sshd: PID 3122: fatal: seteuid 1050745: No such device or address

I even tried running in "single instance mode" (or whatever it's called when you run sshd directly from the terminal as I did previously) and launched strace in an administrative command prompt (after determining the Windows pid with ps -W).  The result was a few zero return codes.
