Since win10 you have openssh ssh.exe in

C:\Windows\System32\OpenSSH

So to use passwordless ssh connection you maybe need to provide ssh.exe “PubkeyAcceptedKeyTypes=+ssh-dss”

For this you can create ssh_config file anywhere (for example in c:\users\yourname\.ssh near your id_dsa private key file) with only one line:

PubkeyAcceptedKeyTypes=+ssh-dss

so now you can:

ssh yourname@1.1.1.1 -F "c:\users\yourname\.ssh\ssh_config"

where 1.1.1.1 for example your ssh server, san_switch, HPE virtual connect manager, nimble storage and so on

ps
the same is true for openssh server installed from home site on win2016 server
only ssh.exe file will be in
“C:\Program Files\OpenSSH-Win64” (by default installation)
