CENG 781 - Network Security - Term Project

Let's compile blindbox.p4 and bring up a switch in Mininet to test its behavior.

1. In your shell, run:

   pip install -r requirements.txt
   

   This will install the dependencies needed for the project.

2. In your shell, run:

   make run

   This will:

   • compile blindbox.p4, and
   • start a Mininet instance with a single switch (s1), connecting three hosts
     (h1, and h2).
   • The hosts are assigned IPs of 10.0.1.1, and 10.0.2.2.

3. You should now see a Mininet command prompt. Open two terminals for h1 and h2, respectively:

   mininet> xterm h1 h2

4. Each host includes a small Python-based messaging client and server. In h2's xterm, start the server:

   python -m client.receiver

5. In h1's xterm, send a message to h2:

   python -m client.sender "This is a safe message."

   The message will be received.

6. In h1's xterm, send a message to h2:

   python -m client.sender "This is a malicious message."

   The message will be received but will be marked as malicious.

7. Type exit to leave each xterm and the Mininet command line. Then, to stop mininet:

   make stop

   And to delete all pcaps, build files, and logs:

   make clean

Cleaning up Mininet

In the latter two cases above, make run may leave a Mininet instance running in the background. Use the following command to clean up these instances:

make stop
