       <p>You need to have an iperf3 server running on the target machine.
 	<br>Note that the default port for iperf3 is 5201 but MP's use 5001.
       <p>The service uses the <a href="http://en.wikipedia.org/wiki/Iperf">iperf3 program</a> for the probing, please refer to that for technical details.
-      <p>It works by starting iperf session from the host you are accessing towards the selected target host and waits for the results. This takes som time to do because of inherent mode of operation. 
-	<li>You may run the iperf program manually on your own host as client or server. 
-	<li>Iperf is available as a comman line
-version and also with a more visual Java based interface.
-	<li> Download from <a href="http://iperf.sourceforge.net/">iperf.sourceforge.net</a> .
+	<h3>Running your own iperf server</h3>
+	If you want to test against other systems you need a path with and open UDP port towards it.
+	You can not initate direct iperf sessions to the measurement beacons because of security reasons.
+	<ul>
+	  <li>iperf3 is not downward compatible - so get it from http://software.es.net/iperf/ .
+	  <li>run it as a server with typically :   iperf3 -s -p 5001
+	</ul>
+
+<h3>How it works</h3>
+It works by starting iperf session from the host you are accessing towards the selected target host and waits for the results. This takes som time to do because of inherent mode of operation. The javascript interface starts iperf commands on the web server to do the testing.
