What is the filter expression to only sniff ICMP packets given the source IP address is 18.104.22.168 and the destination IP address is 22.214.171.124? The filter order must start with the protocol name first, source IP then destination IP.
I tried to use the following expression:
tcpdump icmp src net 126.96.36.199 dest net 188.8.131.52
But it did not work. Could I please have some help?
