nmap [Scan Type(s)] [Options] {target specification} 命令参数分为三个部分，Scan Types 指探测类型，如 -PS 指 TCP SYN Ping，-PA 指 TCP ACK Ping，-PU 指 UDP Ping 等等；Options 指探测选项，如 -n 指不对活动的 IP 地址进行反向域名解析，用以提高扫描速度，-R 指对活动的 IP 进行反向域名解...
1. Intense scan (详细扫描) nmap -T4 -A -v 192.168.1.101 2. Intense scan plus UDP (UDP扫描经典使用) nmap -sS -sU -T4 -A -v 192.168.1.101 3. Intense scan, all TCP ports (TCP扫描) nmap -p 1-65535 -T4 -A -v 192.168.1.101 4. Intense scan, no ping (无Ping扫描) nmap -T4 ...
在准备了必要的IP地址文件,并对主机发现参数优化后,我们就得到最终的扫描命令: nmap -S [srcip] -d –max-scan-delay 10 -oAlogs/tcp-allports-%T-%D -iL tcp-allports-1M-IPs –max-retries 1–randomize-hosts -p- -PS21,22,23,25,53,80,443 -T4 –min-hostgroup 256 –min-rate175 –max-...
Scan a specific port instead of all common ports: sudonmap-p80scanme.nmap.org Copy To scan for TCP connections, nmap can perform a 3-way handshake (explained below), with the targeted port. Execute it like this: sudonmap-sTscanme.nmap.org Copy To scan for UDP connections, type: sudonmap...
The simple default scan above will check the 1000 most well known ports for each IP address. What if you want to scan ALL ports of the IP range under scope. Let’s see how to run this: Assume we want to find all open ports in class C subnet 192.168.10.0/24 1st way nmap -p- 19...
nmap --scanflags SA target # 可以组合使用,SA=SYN+ACK # 进行“IDLE扫描”。IDLE扫描利用目标主机上的开放端口来隐藏扫描者的身份,从而实现匿名扫描。 nmap -sI zombie_host target # 执行SYN扫描。响应一个RST(复位)数据包,表示该端口是关闭的;如果目标主机不响应,或者响应一个SYN/ACK数据包,表示该端口是开...
details when version detection has been requested. When an IP protocol scan is requested (-sO), Nmap provides information on supported IP protocols rather than listening ports. #nmap根据不同的输入选项,输出不同的扫描结果列表。列表列出了端口、协议、服务名称和状态,状态有开放、过滤、已关闭、未过滤,...

This behavior can be changed by modifying or removing the Exclude directive in nmap-service-probes, or you can specify --allports to scan all ports regardless of any Exclude directive. --version-intensity intensity (Set version scan intensity) . When performing a version scan (-sV), Nmap ...
