title: How to point ssh to config file
body: <p>I just switched local systems so I have to get back into a server again using the ssh keys. I usually use <code>ssh david@server</code> to get in. But since I have switched to the new machine the only way I can get into the server is <code>ssh -i path/to/id_rsa_server david@0.0.0.0</code> which points to the private key on my machine. </p>
  
  <p>Now I already have a config file set up in the <code>.ssh</code> folder which I copied over from the last machine. The file looks as such:</p>
  
  <pre><code>Host server
      Hostname 0.0.0.0
      User david
      IdentityFile ~/.ssh/id_rsa_server
  </code></pre>
  
  <p>How do I get the ssh system to recognize the config file again?</p>
