Thanks, NetPacket::ICMP looks great and I know I will need to decode the ICMP packet once I can figure out how to recv() it...
in reply to Re: udp recv question
in thread udp recv question
My question is a UDP->ICMP question.
I am sending out a UDP packet, which in the examples I have seen is valid and my example works correctly (when viewed from a sniffer type product).
When a UDP port isn't available on the remote machine a ICMP unreachable packet is sent back.
I can't figure out how to "read" that packet...and that is my question.
