    21 During your approved time slot, you will be able to log into the console of the respective grid. Currently, this requires a two step process. You first need to log into '''gateway.orbit-lab.org''' with your Orbit credentials using [http://www.openssh.com/ SSH]. From there you then can log into the console corresponding to the following table:

     43Orbit provides a sophisticated framework to efficiently collect measurments at runtime into a database. This database is accessible to the experimenter during the experiment from the console. At the end of an experiment, the database is copied to an external machine and is accessible without a reservation. More information can be found [wiki:OML here].

    46 they can log using ssh and then access the grid using their account.

    48 In order to run the default experiment, simply type the following at the console:
    49         user# > nodehandler –t
    50 This will launch the default tutorial experiment. The tutorial experiment uses nodes 1-1 and 1-2 on the grid. Node 1-1 sends UDP datagrams of 1024 bytes to Node 1-2 at 300 Kbps CBR. The receiver reports the measured throughput.
    51 
    52 To run any experiment that has been defined by the user simply type the following at the console:
    53         user# > nodehandler  <test_script_name>
    54 Here, “test_script_name” is the user’s own script.
    55 More information on running experiments is available here.
