 The mesoscale GENI resources are connected on Layer 2, which enables Layer 2, i.e. non-IP experiments. In this exercise we are going 
 to run a layer 2 ping program, where we are going to send raw Ethernet frames of a custom Ethernet type to a server and receive a reply.

    '''NOTE 1:''' If your node is '''pg32.emulab.net''' or '''pg33.emulab.net''', you will need to do some extra work to login to the node. The control interface of these nodes is behind a firewall so you will login to your node through 'ops.pgeni.gpolab.bbn.com'. Run
