Software-defined networking (SDN) has recently attracted both researchers in academia and big players in communication technologies, and is currently probably the 'hottest' topic in computer networking. This course is a continuation of the "Introduction to SDN" course and we will focus on gaining an advanced knowledge of SDN. | Software-defined networking (SDN) has recently attracted both researchers in academia and big players in communication technologies, and is currently probably the 'hottest' topic in computer networking.

* Exercise IX: | * Exercise IX: Pyretic Debugging (Exempt: Omar, Martin, Thomas, Sameer, Eeran) | ||
'''HINT:''' You might have to use the "$ dpctl dump-flows tcp:127.0.0.1:6634" or "mininet> dpctl dump-flows" command frequently. | |||
** In this debugging exercise, we take solutions available in the Internet for the gardenwall problem and try to fix bugs in it. | |||
** We have done kinetic firewall in exercise VII and imitated the same firewall using pox in exercise VIII. Now, we will imitate the same firewall using pyretic. | |||
** The basic solution is taken from the Internet [https://dl.dropboxusercontent.com/u/1652374/SDN_Course/Exercises/pyretic_gardenwall_internetsolution1.py], test if it is able to block h1 when "infected". Note that we will only use the "infected == True" for this exercise. | |||
*** Copy the above code into /home/mininet/pyretic/pyretic/examples as gardenwall_internetsolution.py | |||
*** start controller (in /home/mininet/pyretic folder): pyretic.py pyretic.examples.gardenwall_internetsolution | |||
*** start mininet: sudo mn --controller=remote --topo=single,3 --mac --arp | |||
*** check h1 ping h2 | |||
*** Now infect h1 (in /home/mininet/pyretic/pyretic/kinetic folder): python json_sender.py -n infected -l True --flow="{srcmac=00:00:00:00:00:01}" -a 127.0.0.1 -p 50001 | |||
*** check h1 ping h2. We should be able to observe that this traffic is blocked. | |||
*** Now, we move on to the debugging part | |||
**** check h2 ping h3, what happens? | |||
**** Now, modify the given code to allow h2 traffic to pass through to h3, when h1 is "infected". | |||
** Now, check if the "exempt" case is working fine too | |||
** if time permits, check and improve code to allow h1 to ping h2 | |||
** If time permits, try fixing [https://dl.dropboxusercontent.com/u/1652374/SDN_Course/Exercises/pyretic_gardenwall_internetsolution.py this] code for the "infected" case. | |||
