title: Git clone a clone but only update remote from 1st clone
body: <p>I have this situation where I have 2 home computers but only 1 is allowed access to a remote machine which hosts the remote repository and for various reasons I can't do my work on this machine.</p>
  
  <p>What I want to do is this:
  remote repo -> clone 1 -> clone 2 (do my work), then
  clone 2 -> clone 1 -> remote repo.</p>
  
  <p>I want to work on clone 2, push to clone 1 then push clone 1 back to the remote repository.</p>
  
  <p>I can do the clone of the clone, but when I try to push back to clone 1, I get an error stating that the master is checkedout and I cannot push to it.</p>
  
  <p>What is the cleanest way to do what I am trying achieve, I am relatively new to git (my current solution is just to copy clone 1, do my changes then copy it back and update - but this causes all sorts of issues).</p>
  
  <p>I have been using sourcetree &amp; tortoisegit, but don't mind some command line work</p>
  
  <p>Cheers</p>
