Many network services use Linux and install Apache server software. Attackers can use NMAP to scan web sites. Now they share their defense experience. In this example, we can set it to make Linux ignore NMAP scanning. The iptables tool is used to filter network information and prevent the system from responding to scan requests. To To improve the security of the server. Run the following command: www

Specifically, it means that a full TCP handshake is completed, but the remote host closed the connection without Receivin G any data.It is import
