    v1 v2  
    1313    i. Each PI (team lead) will have received an email with account registration information.
    1414 b. Generate and upload ssh keys:
    15     Go to http://www.orbit-lab.org/wiki/Documentation/SSHKeys for instructions. Teams are advised that SSH key upload is not possible using Internet Explorer, and hence other browsers are recommended.

    1616 c. Look up your reservation time to use the grid (note, teams also have received their assignments by email). For this hurdle, you will use the general-purpose domains, which are labeled ZDC##, where ## ranges from 01 to 50
    17     i. Go to https://www.orbit-lab.org/schedule/ <https://www.orbit-lab.org/schedule/>  . Access to the schedule requires login information provided in a registration email from the Challenge.
    18     ii. Note that there are a total of 50 general-purpose ORBIT virtual domains that have been set aside for Hurdle 1 and for general usage. These virtual domains  are labeled ZDC##, where ## ranges from 01 to 50, and are different from the USRP-enabled virtual domains that will be used primarily for Hurdles 2 and 3. In order to be fair to all teams and ensure that each team has roughly the same exposure to the same virtual domains, a staggered time assignment has been devised for all teams across all standard virtual domains.  The domains are available to DARPA Challenge teams for 14 hours per day, from 1000 to 2400 (Eastern). Teams should note that if they go to the schedule webpage, https://www.orbit-lab.org/schedule/ <https://www.orbit-lab.org/schedule/> , they may find out  the actual nodes that belong to the virtual domain by hovering their cursor over the domain name (first column) in the schedule. At the end of each 2-hour time slot, teams will be automatically removed from their domain to make that domain available for the next team. Please be advised that this means that experiments that have not completed will be terminated.

    1919 d. Access the domain at the specified time using:
    2020{{{
    2121  ssh username@console.grid.orbit-lab.org
    2222}}}
    23     Teams that are using Windows will need to use an application like PuTTY to open a session to console.grid.orbit-lab.org. An example screen shot of a successful attempt is shown at http://www.orbit-lab.org/wiki/Documentation/Short/Login <http://www.orbit-lab.org/wiki/Documentation/Short/Login>

    2424 e. Image nodes with a specified image (darpahurdle1.ndz):
    2525{{{
    2626  omf load -i darpahurdle1.ndz -t system:topo:all
    2727}}}
    28     Note that the inclusion of "all" in the above command images all nodes within the team's virtual domain (in this case, two nodes). The execution and completion of this command will take several minutes as software is being installed onto the nodes.

    4040If successfully executed, the script will create a database on the OML server with a database name that has the team's username and timestamp. An automatic checker will monitor the database for a successful completion entry, at which time an email containing the instructions for Hurdle 2 will be sent to the team leader.[[BR]]
