     82         <h3><u> Step 3: View Results: </u></h3>
     83         For this example experiment we used the install script facility to automatically install the necessary software and kick-off the experiment. In this very simple setup, we have installed and launched a
     84<a href="[http://en.wikipedia.org/wiki/Web_server" target="_blank"> web server </a> as well as an <a href="http://en.wikipedia.org/wiki/Iperf" target="_blank"> iperf server</a>, on the server host. On the client, we have started some processes to test both of these services. To view the results of this experiment:
     85            <table border="0">
     86              <tr>
     87                <td >
     88                 <ol type="a">
     89            <li> After the background of your slice turns green, press the (i) button that is on the server node icon.</li>
     90            <li> In the information tab that came up, press the <b>Visit</b> button. A new tab should come up that looks like the picture on the side. </li>
     91            <li> Click the <b>Web Server Statistics</b> link to look at statistics. Refresh the page a couple of times to see how the statistics change as the client requests documents.</li>
     92            <li> Click the <b>Logs from the iperf Server</b> link to see the statistics from the iperf transfers.</li>

     98              <h3><u> Optional Step 4: Manually generate traffic: </u></h3>
     99             While conducting experiments in GENI, you will often want to run commands directly on the nodes. In this optional step, you will log in to a node and issue commands directly to it.
     100              <ol type="a">
     101                 <li>  Follow <a href="http://groups.geni.net/geni/wiki/HowTo/LoginToNodes" target="_blank"> these instructions</a> and log in to the client node </li>
     102                 <li> When you have successfully logged in, run this command:<br>
     103<code>
     104iperf -c server -P 2
     105</code> <br>
     106    This task shouldn't take more than 30 seconds. Change the number after the ` -P ` argument and watch how the performance is affected while you change the number of parallel TCP connections.
     107     </li>
     108   <li> Scroll all the way down the server iperf log, and look at the logs for your transfers </li>

     124              <h3><u> Step 5: Cleanup experiment: </u></h3>
     125           After you are done with your experiment, you should always release your resources so that other experimenters can use
     126the resources. In order to cleanup your slice :
     127              <ol type="a">
     128                 <li>Press the <b>Delete</b> button in the bottom of your canvas </li>
     129                 <li> Select <b>Delete at used managers</b> and <b>confirm</b> your selection. </li>
     130              </ol>
     131Wait and after a few moments all the resources will have been released and you will have an empty canvas again. Notice that your slice is still there. There is no way to delete a slice, it will be removed automatically after its expiration date, but remember that a slice is just an empty container so it doesn't take up any resources.
