I just noticed if id_rsa.pub exists in local ~/.ssh directory, I can't connect my remote server with ssh command.
But I have no idea why is that. Is it dangerous for security if public key exists at same place of secret key?
And I don't get a error that indicates the public key should not be placed there, even if I run ssh command with -v option.
Why I must not put a public key in ~/.ssh/?
This is a part of ssh log with -v option. I'm using ssh in cygwin environment.

Anything logged before that part? It doesn't explain why password isn't a possible authentication. – Daniel Beck – 2014-03-03T18:34:50.197
1It looks like your host is trying to validate off of your public key which is fine. However, your public key does not authenticate successfully. Make sure that you've provided your public key to the host in the
authorized_keysunder the user account in which the key is meant to access. – kobaltz – 2014-03-03T18:50:16.573
