Problem with asyn icmp ping?

A problem you might be having is due to the fact that ICMP is layer 3 of the OSI model and does not use a port for communication. In short, ICMP isn't really designed for this. The desired behavior is still possible but perhaps the IP Stack you are using is getting in the way and if this is on a Windows system then 100% sure this is your problem.

I would fire up Wireshark to make sure you are actually getting incoming packets, if this is the case then I would use libpcap to track in ICMP replies. If the problem is with sending then you'll have to use raw sockets and build your own ICMP packets.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
