nmap使用小结

 更细节的知识请看nmap的manpage,这里主要是解释nmap的一个GTK前端Zenmap中的默认几个扫描命令的选项:

intense scan:

nmap -T4 -A -v www.rickyzhang.me

-T<0-5>: Set timing template (higher is faster)

-A: Enable OS detection, version detection, script scanning, and traceroute

-v: Increase verbosity level (use -vv or more for greater effect)


intense scan plus udp:

nmap -sS -sU -T4 -A -v www.rickyzhang.me

-sS/sT/sA/sW/sM: TCP SYN/Connect()/ACK/Window/Maimon scans

-sU: UDP Scan

-sN/sF/sX: TCP Null, FIN, and Xmas scans


Intense scan, all TCP ports:

nmap -p 1-65535 -T4 -A -v www.rickyzhang.me

-p <port ranges>: Only scan specified ports
               Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080,S:9


Intense scan, no ping:

nmap -T4 -A -v -Pn www.rickyzhang.me

-Pn: Treat all hosts as online -- skip host discovery


Ping scan:

nmap -sn 192.168.1.0/24

-sn: Ping Scan - disable port scan

注:这个用来检测一个子网内有多少机器是在线的


Quick scan:

nmap -T4 -F www.rickyzhang.me

-F: Fast mode - Scan fewer ports than the default scan

注:一般默认nmap会扫描常用的1000个端口,当使用-F后就变成常用的100个端口


Quick scan plus:

nmap -sV -T4 -O -F --version-light www.rickyzhang.me

-sV: Probe open ports to determine service/version info

-O: Enable OS detection

--version-light: Limit to most likely probes (intensity 2)

注:probe:探针 intensity:强度

--version-intensity <level>: Set from 0 (light) to 9 (try all probes)
