     18Welcome to GENI. This page will guide you through your first GENI experiment. The only thing you will need is a GENI account. If you don't already have one, [wiki:SignMeUp sign up!]

     22For our first experiment we are going to use [" Flack] a web-based graphical tool for reserving GENI resources. Your first step is to log in to Flack. [ This video] will guide you through the steps of logging in.

     50Now that you are logged in to Flack, we are ready to design our experiment. [ This video] will guide you through the process of setting up  the resources for the Hello GENI experiment. To complete the setup you will need to save a copy of [ this file] on your computer. This is a [wiki:GENIExperimenter/RSpecs Resource Specification (rspec)] file that contains a description of this experiment for Flack.

     63            <li> After Flack finishes loading all the information, create a new slice by clicking <b>New</b> on the left of the screen, right under your user name. Name your slice something like <b>xxxhello</b> (where xxx are your initials)<br></li>
     64            <li> When an empty canvas shows up, you are ready to create an experiment. Click at the <b>Import</b> button on the top of the canvas and select <b>Import from file </b></li>
     65            <li> Find the  copy of <a href ="attachment:hellogeni.rspec"> this rspec file</a> that you downloaded earlier and press ok</li>
     66            <li>  A topology will come up, it will look different than the topology on the video. Your topology should look like <img border="0" src="" alt="Login to Flack Video"  height="20" title="How to login video" />. Press the <b>Submit</b> button and <b>confirm</b> that you want to reserve these resources.</li>
     67            <li> Wait while your resources are being reserved. This will take several minutes so be patient. When your sliver is ready the background will be green. </li>

     75For 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 [ web server] as well as an [ iperf server], on the server host. On the client, we have started some processes to test both of these
     76services. To view the results of this experiment:

     89            <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>
     90            <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>
     91            <li> Click the <b>Logs from the iperf Server</b> link to see the statistics from the iperf transfers.</li>

     985. ''' Optional: Manually generate traffic ''' 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.
     99  * Follow [wiki:HowTo/LoginToNodes these instructions] and log in to the client node
     100  * When you have successfully logged in, run this command
     101   {{{
     102iperf -c server -P 2
     104    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.
     105  * Scroll all the way down the server iperf log, and look at the logs for your transfers
     107= 4. Cleanup =
     108After you are done with your experiment, you should always release your resources so that other experimenters can use
     109the resources. As shown at the end of the [ video for reserving resources], in order to cleanup your slice :
     110  1. Press the '''Delete''' button in the bottom of your canvas
     111  1. select "'''Delete at used managers'''" and '''confirm''' your selection.
     112Wait 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.
     114= 5. What's next? =
     115Congratulations! You have finished your first GENI Experiment. Now that you are more familiar with GENI concepts you can:
     116  * continue with more [wiki:GENIExperimenter/ExampleExperiments advanced tutorials]
     117  * learn more about how to use Flack by following the [ Flack Tutorial]
     118  * start with your own experiment. This tutorial showed you the basic steps for running an experiment. Use Flack to create your own topology, take a look at the [wiki:HowTo/WriteInstallScript instructions about how to write your own install scripts] to automate your expriment.
