    14 In this tutorial, we will use a large node (s1.lg1) and a medium node (md1) of the 'Main Rooftop SDR Deployment' in [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1 sandbox 1]. More specifically we will use the sdr2-s1-lg1 and sdr2-md1 nodes. These nodes have a USRP Krypton 2974 connected via PCI-e

     23In this tutorial, we will use a large node (s1.lg1) and a medium node (md1) of the 'Main Rooftop SDR Deployment' in [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1 sandbox 1]. More specifically we will use the sdr2-s1-lg1 and sdr2-md1 nodes. These nodes have a USRP Krypton 2974 connected via PCI-e.

    46 === Experiment Execution ===
    47 After setting up the nodes, we can now start exploring the K--12 STEM educational labs. To run the experiments we have developed a user-friendly web interface based on HTML and CSS, and back-end web-server developed in python that will control
    48 and orchestrate the experiments.

    5055To visualize the front-end web interface we need to forward the port 80 of the remote node to the local host. For the sdr2-s1-lg1 we will use port 8081, while for the sdr2-md1 we will use the 8082. To communicate with the back-end server we need to forward the port 8090 of the remote node to the local host. For the sdr2-s1-lg1 we will use port 8091, while for the sdr2-md1 we will use the 8092. Some of the experiments require to use audio at the transmitter or the receiver, for this purpose we create a TCP socket at port 8100 of the remote node. To forward port 8100 we will use port 8101 for the sdr2-s1-lg1, and port 8102 for sdr2-md1. At the host computer we developed a very simple python program that is attached at the bottom of the page. The program connects to the server that is running at the remote node, and outputs the received data to the local audio card.

    66 Now you are ready to start exploring the COSMOS K--12 educational labs. To connect to the web interface of sdr2-s1-lg1 press the following link [https://localhost:8081], and to connect to the web interface of sdr2-md1 press the following link [https://localhost:8081]
     71After setting up the nodes, we can now start exploring the COSMOS K--12 STEM educational labs. To connect to the web interface of sdr2-s1-lg1 press the following link [https://localhost:8081], and to connect to the web interface of sdr2-md1 press the following link [https://localhost:8082]

     73=== Experiment Execution ===
     74First, you need open the web interface of either node. Let's open [https://localhost:8081]. If you did all the above steps correctly you should be able to see the following,
