    120120=== 5.2 (optional) Send non-IP traffic ===
    121121
     122    a. ExoGENI nodes run a service called "neuca" that managed network interfaces on the node.  To manually adjust the IP address, we must first disable neuca on both nodes.
     123{{{
     124sudo service neuca stop
     125}}}
     126{{{

     135        </tr>
     136</table>
     137}}}
     138    b. Disable the IP on both of your nodes (being careful to disable IP on the data interface NOT the control interface).
     139       In each of the terminals type:
     140{{{
     141  sudo ifconfig <data interface name> 0.0.0.0
     142}}}
     143{{{
     144#!html

     150               </td>
     151               <td>
     152                    Be extra careful to disable the IP on the data interface, bringing down the IP on the control interface means that you will lose connectivity to your host.
     153               </td>
     154        </tr>
     155</table>
     156}}}
     157    c. Try again to ping from the client to the server. In the terminal window of the client type:
     158{{{
     159    ping <server data IP addr> -c 5
     160}}}
     161       For example:
     162{{{
     163    ping 10.17.1.2 -c 5
     164}}}
     165    This time the ping should indicate that the destination is unreachable.
