    22 To run the experiment we will use two terminals to login to the ''"right-client"'' and the ''"left-client"'' VMs and one browser to connect to the ''"server"'' VM to review results.
     22To run the experiment we will use two terminals to login to the ''"right-client"'' and the ''"left-client"'' VMs and one browser to connect to the ''"server"'' VM to review results. To get the login information you can use the `readyToLogin` script or the portal. If you don't know how to login to your hosts look at [wiki:GENIExperimenter/Tutorials/StitchingTutorial/AppendixA Appendix A].
     23
     24'''1.''' Open two windows, one that you are logged in to the `right-client` and one that you are logged in to the `left-client`.
    2325
    2426
    25 '''1.''' Start 2 terminal windows and use the `readyToLogin` script to determine the login information for the client hosts:
    26 
    27 Window 1:
    28 {{{
    29 $ readyToLogin -a <rightAggr> MySlice
    30 ....
    31 $ ssh -i right-client....
    32 ...
    33 }}}
    34 Window 2:
    35 {{{
    36 $ readyToLogin -a <leftAggr> MySlice
    37 ...
    38 $ ssh -i left-client....
    39 ...
    40 }}}
    41 
    42 '''2.''' Now let's compare the Round Trip Time over each link type.
    43 
    44 In the ''"right-client"'' terminal issue:
    45 {{{
    46 right-client$ ping -c 20 192.168.1.2
    47 --- 192.168.1.2 ping statistics ---
    48 20 packets transmitted, 20 received, 0% packet loss, time 19020ms
    49 rtt min/avg/max/mdev = 65.143/68.522/132.324/14.640 ms
    50 }}}
    51 
    52 In the ''"left-client"'' terminal issue:
    53 {{{
    54 left-client$ ping -c 20 10.10.1.2
    55 --- 10.10.1.2 ping statistics ---
    56 20 packets transmitted, 20 received, 0% packet loss, time 19000ms
    57 rtt min/avg/max/mdev = 0.057/0.126/1.192/0.244 ms
    58 }}}
    59 
    60 '''3.''' Start a browser and navigate to the ''"server's"''s hostname from the readyToLogin output in previous step. For this example experiment the hostname allocated is pcvm1-15.instageni.stanford.edu:
     27'''2.''' Start a browser and navigate to the ''"server's"''s hostname; if you don't know how to find the hostname look at [wiki:GENIExperimenter/Tutorials/StitchingTutorial/AppendixA Appendix A]. For this example experiment the hostname allocated is pcvm1-15.instageni.stanford.edu:

    8552Add a third terminal window which is logged into the ''"server"'' host.  Determine the 2 Data Plane interfaces and remove the IP of the two interfaces. Take note of the  MAC address for the 192.168.1.2 and 10.10.1.2 interfaces and start the ping listener.
