Step 3: View Results:
For this example experiment we used the install script facility to automatically install the necessary software and kick-off the experiment. In this very simple setup, we have installed and launched a
web server as well as an iperf server, on the server host. On the client, we have started some processes to test both of these services. To view the results of this experiment:
- Follow these instructions and log in to the server node. Get the control interface IP address by typing ifconfig. This IP address should be accessible from the internet. In a web browser, type the IP address found from ifconfig.
- Click the Web Server Statistics link to look at statistics. Refresh the page a couple of times to see how the statistics change as the client requests documents.
- Click the Logs from the iperf Server link to see the statistics from the iperf transfers.

Optional Step 4: Manually generate traffic:
While conducting experiments in GENI, you will often want to run commands directly on the nodes. In this optional step, you will log in to a node and issue commands directly to it.
- Follow these instructions and log in to the client node
- When you have successfully logged in, run this command:
iperf -c server -P 2
This task shouldn't take more than 30 seconds. Change the number after the ` -P ` argument and watch how the performance is affected while you change the number of parallel TCP connections.
- Scroll all the way down the server iperf log, and look at the logs for your transfers
