USING P4_INT

[euclidesfjr]

Hi, good morning, can you help me? Because in the test that I am working on I can not make the system work properly, because I do not know how to use the * .py commands below, since I can only generate send packets, receive packets do not generate and consequently do not generate the network analysis when I use this program. Can you help me?

Because I can not generate * .pcap files for IN (input), only OUT (output). Can you help me? Since I can not get the network to communicate between IP addresses.

Hi @euclidesfjr, Please run the send_udp.py file on the h1 host and receive_udp.py script on the h8 host. Also please ensure that before running p4 code your hosts are able to ping each other.

Hi, good morning, thank you very much for your attention, but I'm not able to execute. Maybe I did not understand the program send_udp.py and the program send_tcp.py, because when running it does not work, even though I see the arguments it asks, see how I executed it.

Okay, but how to do this ?? "Also please ensure that before running your hosts are able to ping each other."

Thanks very much for the help, I need to be able to do an article about it.
