UDP port unreachable / destination unreachable

1 post in this topic

Hello!

I try to send an UDP-Packet to a machine xx port yy.

UDPsend always returns the number of bytes sent, wether the target-Port on the server-side is listening, or not. (thats ok, just like stated in AutiIT-Help)

When the Target-Port is not listening, the Target alway sends back an ICMP-packet containg "destination unreachable" and "port unreachable" .

My question is, how to deal with this message to take action in autoit-script?

How can i get a handle to this ICMP-message,?

tnx!
