And the second part of the test is sending a bad UDP datagram.
Compile this code and run it on a different computer, as root, specifying the IP address of the first computer as the command-line parameter.
Wireshark shows a UDP datagram coming in with a bad checksum.
The first computer will print out: poll() reported readability but recvfrom got EAGAIN
Theory proven.
