title: etcd error when trying to list machines
body: <p>I am experimenting with etcd and have been able to get it running in a cluster and performing most of the expected functions.  However, I am trying to execute some basic admin and monitoring requests and am getting unusual errors. </p>
  
  <p>I execute the following command (in the COREOS <a href="https://coreos.com/etcd/docs/0.4.7/etcd-api/#cluster-config" rel="nofollow">documentation</a>):</p>
  
  <pre><code>curl -L http://127.0.0.1:7001/v2/admin/machines
  </code></pre>
  
  <p>and I get the following response:</p>
  
  <pre><code>404 page not found
  </code></pre>
  
  <p>Note:  I confirmed that is etcd working (as I can see other commands work perfectly well).</p>
  
  <p>My configuration is as follows:</p>
  
  <pre><code>$ etcd --version
  
  etcd Version: 2.3.0
  Git SHA: 5e6eb7e
  Go Version: go1.5.3
  Go OS/Arch: darwin/amd64
  </code></pre>
