title: fatal: remote server hung up unexpectedly
body: <p>I've looked at the other threads with similar questions, but I'm new to git, so most of it didn't make sense :(</p>
  
  <p>Here's the problem:</p>
  
  <p>I can't push a simple readme onto my repository on github.</p>
  
  <p><code>$ ssh -T git@github.com</code> seems to be working fine.</p>
  
  <p>But whenever I push the README using the following:</p>
  
  <pre><code>$ git push origin master
  </code></pre>
  
  <p>I get the following error - </p>
  
  <pre><code>ssh: connect to host githum.com port 22: Connection timed out
  fatal: The remote end hung up unexpectedly
  </code></pre>
  
  <p>Notice that it says the host is 'githum.com'. So I must have made a typo when I was setting up the ssh keys for git. How do I correct this and make sure the remote end works properly?</p>
