title: OpenSSH offers wrong public key?
body: <p>I try to configure ssh to use two remotes which each a different key pair. Therefore, I created this <code>config</code>.</p>
  
  <pre><code>UserKnownHostsFile ~/.ssh/known_hosts
  
  Host github.com
      User git
      PreferredAuthentications publickey
      IdentityFile ~/.ssh/github_rsa
  
  Host git.cloudhost.io
      User git
      PreferredAuthentications publickey
      IdentityFile ~/.ssh/cloudhost
  </code></pre>
  
  <p>The connection to Github works fine.</p>
  
  <pre><code>&gt; ssh -T github.com
  Hi danijar! You've successfully authenticated, but GitHub does not provide shell
  access.
  </code></pre>
  
  <p>But for Cloudhost, the connection fails.</p>
  
  <pre><code>&gt; ssh -T git.cloudhost.io
  Permission denied (publickey,password).
  </code></pre>
  
  <p>Here is the debug output for Cloudhost.</p>

  <p>The line <code>Offering public key: /c/Users/Name/.ssh/cloudhost</code> confuses me, because <code>cloudhost</code> is the private key. The public key is named <code>cloudhost.pub</code>.</p>
  
  <p>How can I connect as my login user via ssh to Cloudhost?</p>
