    173173Before being able to run this experiment, you should:
    174174
    175  * [http://www.orbit-lab.org/register Register] for an account (if you have not done so yet)
    176  * [https://www.orbit-lab.org/schedule/ Make a reservation] on the Scheduler for a time slot on one of the sandbox testbed
    177  * Log into the console machine corresponding to this testbed. To control the Node Handler, your experiment, and the nodes on the testbed(s), you will use the generic '''orbit''' command and its options.
     175 * Make sure you have followed the getting started procedure [wiki:Documentation/GettingStarted getting started]
     176 * Once you have proper reservation, login to the console.
     177 * Install a disk image which includes ''Ex'' on the nodes of this testbed. For example, you can use the latest ''baseline.ndz'' disk image. This disk image installation is done using the ''omf load'' command above. Detailed instructions on how to perform such disk image installation on the nodes on a testbed can be found [wiki:Tutorials/HowToImage here].

    179   # User Bob reserved a time slot on the sandbox1 testbed.
    180   # He then can access the sandbox1 console using the command:
    181  
    182   ssh bob@console.sb1.orbit-lab.org
    183 
    184   # To see a list of commands available through the orbit command:
    185   orbit help
    186 
    187   # which will give the following output
    188   Run a command on the testbed(s)

    216 Normally an experiment is described in a script file, e.g. "my_experiment.rb", which is run by using the command "omf exec my_experiment". However in this particular case, the tutorial script is already stored in a repository known by the ''omf exec'' application. Thus the "--tutorial" option instructs the ''omf exec'' application to fetch that script and execute it.
