filtering icmp traffic to/from specific host
$ sudo tcpdump -n icmp and host 10.16.100.5
also we can use the parameter -c[0-9] for only capture a defined number of packets
others parameters like port when we are setting tcp/udp are also useful
$ sudo tcpdump -i any -c5 -nn "port 80 and (src 192.168.10.125 or src 154.24.4.231)"
other useful parameter is A, that one can show us the package content, it doesn't have any decrypt functionality
