P40f

To run in Mininet on the P4 tutorials VM:

1. Change directory to ./src, then run make.
2. In another terminal window, run the controller: python controller.py. This installs fingerprinting rules onto the switch.
3. To replay a packet capture through the switch, open h1's terminal by running xterm h1 in Mininet, then run tcpreplay -x 0.1 -i "h1-eth0" [PCAP FILENAME].pcap in h1's terminal. The replay speed 0.1 can be adjusted if necessary.
4. We can produce a text file p4_result.txt containing an OS label for each TCP SYN packet in the capture as follows:
   • Run grep "Action entry is MyIngress.set_result" logs/s1.log > grep_result.txt.
   • Run python p4_result.py > p4_result.txt.
