But, as we know, The Linux network component creates two special purpose sockets for use by the AF_INET protocol family. The tcp socket is used to send resets when a TCP packet is rejected, since there may be no local socket corresponding to the packet. The icmp socket is used to send ICMP messages. Then, Why did you say that ping replies (ICMP echo replies) were not associated with a socket? Is there any difference between the special purpose socket and the socket you mentioned above?
