Can some one help ? I have installed openssh (version OpenSSH_6.8p1, OpenSSL 1.0.2a) in windows 7 and I have generated the public and private keys, however I'm not able to connect to that SSH. I'm getting an error "Connection closed by 127.0.0.1" if I use the command "ssh localhost" .

However I'm able to connect by skipping the public key authentication via "ssh localhost -o PubkeyAuthentication=no"

Output of the command "ssh -v localhost"

  • Sounds permissions issue. Do the user attempting to use the keys (your user presumably) own and have read access to the folder and keys themselves? – linuxdev2013 Jun 12 '15 at 1:14
