Thanks.. 

I reinstalled cygwin so as to update setfacl to include -b and then ran that command and then ssh works.

Note the extra permissions indicated by the trailing '+'.  Try
`setfacl -b /etc/ssh_host_ed25519_key'.

can't change a file's permissions + some ssh

[Marilo]

after some fiddling with ssh.. removing the service, removing keys, re-running ssh-host-config, I got this error 

harvey@samsung350 ~ 
$ tail /var/log/sshd.log 
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @ 
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 
Permissions 0670 for '/etc/ssh_host_ed25519_key' are too open. 
It is required that your private key files are NOT accessible by others. 
This private key will be ignored. 
bad permissions: ignore key: /etc/ssh_host_ed25519_key 
Could not load host key: /etc/ssh_host_ed25519_key 
Disabling protocol version 2. Could not load host key 
sshd: no hostkeys available -- exiting.


So I tried changing the file's permissions but I can't seem to change them

harvey@samsung350 ~ 
$ ls -l /etc/ssh_host_ed25519_key 
-rw-rwx---+ 1 cyg_server root 411 Jun  7 17:23 /etc/ssh_host_ed25519_key 

harvey@samsung350 ~ 
$ chmod 600 /etc/ssh_* 

harvey@samsung350 ~ 
$ ls -l /etc/ssh_host_ed25519_key 
-rw-rwx---+ 1 cyg_server root 411 Jun  7 17:23 /etc/ssh_host_ed25519_key 

harvey@samsung350 ~ 
$ 



I can run 
$ echo asdf>c:\fffdfs   So I do have administrative permissions.
