Does anybody knows how to implement the echo service with arduino? I need to retransmit all the received packets. Thanks.
How can you retransmit an ICMP echo packet? It would be addressed to yourself, or? What is the purpose of your system?
(search for ICMP ping and UDP in the upper right might give some hints)
I have an equipment to test Ethernet link quality that sends ICMP packets to analize the errors. I have to use two equipments, one in a point of the link to send the packets and analyze them and one in the other link to resend the packets using the ICMP echo service. I'd like to replace the second equipment with the arduino. Thanks.
