-====== Ping - Block TCP ping ======
-You can easily block tcp ping from nmap using a stateful firewall like iptables.  tcpping in nmap works by sending an ACK packet, for which a RST packet is send back by the host.
-Now this ACK packet send is not part of any previously made connection to the host.  This kind of packets can be easily blocked by iptables.
