1, Port scanPort scans are often used by system administrators and hackers to discover ports that are open on some machines to help them identify vulnerabilities in the system.NC-ZVN 172.16.160.111 21-25Can be run in TCP or UDP mode, by default the Tcp,-u parameter is adjusted to UDP. # #udp测试 No matter what port is detected successedThe z parameter tells Netcat to use 0 IO, Close the connection immediately after the connection is successful, and no data exchangeThe V parameter refers to the use
host, because there is a difference between a simple (basic) scan and a pre-scan. We need to use some advanced technologies to bypass firewalls and intrusion detection/defense systems to obtain the correct results. Below are some basic commands and their usage examples: scan a single host, the command is as follows:
The Code is as follows:

Nmap depends on the target host, as there is a simple (basic) scan and the difference between pre-scanning. We need to use some advanced techniques to bypass firewalls and intrusion detection/defense systems to get the right results. Here are some basic commands and examples of their usage: Scan a single host with the following command:The code is as follows:#nmap

What is a firewall?A firewall is software or hardware used to control network access. There are two types: 1. Host-Based firewall; 2. Network-based firewall.Host-Based FirewallThis software runs on a single host to control inbound traffic (from network to host) and outbound traffic (from host to network ). These software are installed on the operating system. Common

NMAP is a network detection and security scanning program. System Administrators and individuals can use this software to scan a large network and obtain information about the host running and what services it provides. NMAP supports many scanning technologies, such as UDP, TCP connect (), tcp syn (half-open scan), and FTP Proxy (Bounce Attack), reverse flag, ICMP, FIN, Ack Scan, Christmas tree (Xmas tree),
