Need admin privs before something can inherit them (was Re: ssh-host-config doesn't "inherit" user admin privilege)

Yes, I did a right-click on the cygwin terminal icon and chose a "run as administrator" option. This is like doing a sudo to start a linux shell... everything run in the shell inherits "admin"/"root" as appropriate. Followed by using this shell to do:

cd /usr/bin
./ssh-host-config

I entered 'yes' responses to the various setup questions including yes to privileged separation. I never bumped into this sort of inheritance problem in Windows 7 and earlier. Seems to be a Windows 10 "feature". This past week I ran into the same problem using an Intel supplied command script to install their hydra_mpi server. Another knowledgeable Windows 10 user reports he, too, has encountered this issue.

After installation I do some local tweaks to sshd_config such as disablng plain-text password logins. I'm able to succesfully connect using ssh/sftp from other platforms to this system using public key authentication. Windows is configured to autostart cygsshd.

I can add that I previously added C:\cygwin64 to the list of Windows Defender exceptions.

Yes, I used to do a lot of work on Control Data Cyber205s, ETA-10s and Cray C90s. Practically speaking vector operations can make effective use of memory bandwidth.
In other words, a vector a day keeps the scalars away! 

Regards,

Art

You say ssh-host-config tries to install cygsshd.  How was ssh-host-config
called (started)?  When Cygwin64 Terminal was run, it was run with Admin
at the start.  Was that done when ssh-host-config was run?

How was it run?

You like vectoring, I take it?  :-)?
Cheers!
