the size of the Ip works, but when I get the tcp packet, things don't work
as planned--it gives invalid ports.
I see:
tcp = (tcp_hdr *) ((packet + sizeof (ether_hdr)) + ip_size);
cout << "Source port: " << tcp->th_sport << "\t\tDestination port: " << tcp->th_dport <<

Hello list,
I'm still working on this for college.
I rewrote my callback function to work a bit differently, but it's still giving
