v4 v5 15 15 == Ssh'ing into nodes from the GENI Desktop == 16 16 17 To open an ssh session, you must first launch the ssh tool. You can launch the ssh tool by clicking the '''SSH''' [[Image(wiki:GEMINI/Tutorial/Images:modules.png)]] button in the upper lefthand corner of the GENIDesktop This will create an ssh button [[Image(wiki:GEMINI/Tutorial/Images:ssh.png)]] near the task bar on the bottom. To ssh into nodes, select the node in the topology by left-clicking on the node. Once selected, press the ssh button to ssh into your network. You may need to accept the security certificate if prompted by your browser. You can iconify the ssh button or de-iconify the ssh button by clicking ssh in the task bar.17 To open an ssh session, you must first launch the ssh tool.

Iperf needs to be run on both the source and destination node. Iperf should first be started at the destination in server mode using the command "iperf -s." To run iperf on the source, type "iperf -t 60 -b 100M -c destination" where destination is the IP address (or name) of the node where the iperf server is running. This will tell iperf to generate traffic for sixty seconds, sending at a rate of one hundred megabits per second. The names of the hosts in your topology can be found in the /etc/hosts.33 The iperf program can be used to generate traffic. Iperf needs to be run on both the source and destination node.

'''Task 1:''' Ssh into VM-0 and VM-1.40 a. '''Task 2:''' Use iperf to generate traffic between VM-0 and VM-1.41 a. '''Task 3:''' View the traffic between VM-0 and VM-1.38 a. '''Task 1:''' Ssh into Node-0 and Node-1. 39 a. '''Task 1:''' Install iperf on each node (Hint : use command "apt-get update;apt-get install iperf;") 40 a. '''Task 2:''' Use iperf to generate traffic between Node-0 and Node-1. 41 a. '''Task 3:''' View the traffic between Node-0 and Node-1.
