+= Step 4: Execute Experiment =
+
+To run the experiment we will use:
+ - two terminals to login to the ''"right-client"'' and the ''"left-client"'' VMs
+ - one browser to connect to the ''"server"'' VM
+
+But first we must determine which nodes have been allocated to our experiment.
+
+
+'''1.''' Open first terminal, use the readyToLogin script to determine the login information, and login to ''"right-client"''. If you are following along as part of a tutorial use the aggregates assigned to you!!
+{{{
+$ readyToLogin -a rightAggr MySlice
+....
+
+$ ssh -i right-client....
+
+}}}
+
+  Where ''"rightAggr"'' is the aggregate where you have requested the VM named ''"right-client"''.
+
+For the experiment in this tutorial we use: 
+{{{
+$ readyToLogin -a wisconsin-ig MySlice
+...
+
+$ ssh -i ... lnevers@xxx
+}}}
+
+'''2.''' Open a second terminal, use the readyToLogin script to determine the login information, and login to ''"left-client"''. If you are following along as part of a tutorial use the aggregates assigned to you!!:
+{{{
+$ readyToLogin -a leftAggr MySlice
+...
+
+$ ssh -i left-client....
+
+}}}
+   Where ''"leftAggr"'' is the aggregate where you have requested the named ''"left-client"''.
+
+For the experiment in this tutorial we use:
+{{{
+$ readyToLogin -a stanford-ig MySlice
+...
+
+client's geni_status is: ready (am_status:ready) 
+User lnevers logs in to client using:
+        ssh -i /Users/lnevers/.ssh/geni_cert_portal_key lnevers@pcvm1-12.instageni.stanford.edu
+
+left-server's geni_status is: ready (am_status:ready) 
+User lnevers logs in to left-server using:
+        ssh -p 34107  -i /Users/lnevers/.ssh/geni_cert_portal_key lnevers@pc1.instageni.stanford.edu
+
+$ ssh -p 34107  -i /Users/lnevers/.ssh/geni_cert_portal_key lnevers@pc1.instageni.stanford.edu
+
+}}}
+
+'' '''Note:''' '' The ''"server"'' VM has been allocated with a routable IP address and been assigned a hostname that resolves to the following FQDN ''"pcvm1-12.instageni.stanford.edu"''
+
+'''3.''' Before we run the experiment, start a web browser and navigate to the FQDN hostname from step 3. For the experiment in this page we browse to:
+ 
+     [[Image(LuisaSandbox/StitchingTutorial/attachments:client-web.jpg)]]
+ 
+'''4.''' In first terminal to ''"right-client"'' install iperf and send traffic to the server over the stitcher path:
+{{{
+right-client$ sudo yum install iperf -y
+right-client$ /usr/bin/iperf -c 10.10.1.2 -t 30 -P 10
+}}}
+
+'''5.''' In the second terminal to ''"left-client"'' install iperf and send traffic to the server over the local link:
+{{{
+left-client$ sudo yum install iperf -y
+left-client$ /usr/bin/iperf -c 10.10.1.2 -t 30 -P 10
+}}}
+
+'''6.''' Now back to the browser; Refresh the web page and you should see the results from the iperf process listening on the server:
