    169169We use Atheros AR5212-based 802.11 a/b/g cards as well as Intel Pro-wireless 2915-based 802.11 a/b/g cards. Nodes with x+y = even are Intel nodes where as x+y= odd are Atheros nodes.e.g node1-1 = Intel, node1-2 = Atheros and so on.

     171Software Questions
     172===================
    171173
    172174What OS do the nodes run?
     
    180182Yes, you can run your own OS (or a customized version of an ORBIT-supported OS) on any of the radio nodes. We provide infrastructure to image the nodes involved in the experiment with the provided OS image.
    181183
    182 Can I load my own software packages on my nodes?
    183 ------------------------------------------------
    184 
    185 Yes! If have one or more software packages that are appropriate for loading on the OS you have selected, you can arrange to have them loaded automatically via APT package system when your experiment is configured. You may specify a different list of software packages for each radio node in the experiment. When the node first boots after the experiment is configured, each of the packages will be installed.

    187185How do I access the nodes?
     
    190188 * ssh root@nodex-y

     191Can I load my own software packages on my nodes?
     192------------------------------------------------
     193
     194Yes! If have one or more software packages that are appropriate for loading on the OS you have selected, you can arrange to have them loaded automatically when you configure your experiment. You may specify a different list of software packages for each radio node in the experiment.  There are no restrictions on what you put on the nodes.
     195
     196How do I install software on the nodes?
     197---------------------------------------
     198
     199This is a broad question.  During your slot, the nodes are yours to do what you will, right down to the OS.  If the experimenter requires his/her own OS, then installation of software is carried out using methods appropriate for that particular OS.  There are no restrictions as to what/how software is installed on the node.
     200
     201If you would like to use the ORBIT supplied baseline images, which run Debian GNU/Linux, then software is installed via [http://www.debian.org/doc/user-manuals#apt-howto APT].  The testbeds have access to a local Debian mirror which is updated nightly.  Anything available on the global Debian mirrors is locally accessible on orbit via the local Debian mirror.
     202
     203Also, the baseline image has all of the normal Linux build components installed.  You are more than welcome to compile from source and use your software through those mechanisms.
     204
     205
    192206Is the ORBIT testbed firewalled?
    193207--------------------------------
    194208
    195 Yes.
     209Yes.  The nodes and their consoles do not have direct access to the Internet.  However, the machine used for initial login, "gateway.orbit-lab.org", does.  Since your home directory on gateway is also accessible via the testbed consoles, it is possible to upload and download from the Internet on "gateway.orbit-lab.org" and copy files to your nodes from the testbed console.
