Hello,
I have an issue in the part 4 of the lab 3, when we are trying to send multicast messages. When I run both my receiver.py and my sender.py in the VM, I'm able to see the input message (along with the SCIPER) I send in the receiver's terminal.
However, when I submit it for grading on the grading system, I get 1/5 and all the tests that fail tell me that they can't find the message beginning with the chosen SCIPER. In the logs, I can see that all tests result in an "OSError: [Errno 98] Address already in use", despite having clearly set "sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)" before binding the socket. Do someone know here it may come from?
Thanks!
