学习Nmap端口扫描的高级技术,例如空扫描、FIN扫描、Xmas扫描和空闲(僵尸)扫描、数据包欺骗,以及FW(防火墙)规避、IDS规避等。
在Nmap中有四种类型的规则,prerule用于在Nmap没有执行扫描之前触发脚本执行,这类脚本并不需用到任何Nmap扫描的结果;hostrule用在Nmap执行完毕主机发现后触发的脚本,根据主机发现的结果来触发该类脚本;portrule用于Nmap执行端口扫描或版本侦测时触发的脚本,例如检测到某个端口时触发某个脚本执行以完成更详细的侦查。postru...
postrule 此案例中,重点介绍portrule。portrule能够在执行操作前,检查host和port属性。portrule会利用nmap的API检查TCP80端口。 The Action Section 该部分定义脚本逻辑。此处案例中,检测到开放80端口,则打印“HelloWorld”。脚本的输出内容,会在nmap执行期间显示出来。
Use Cases for UDP Port Scan Allows you to discover which UDP ports are open on your target host, identify the service versions, and detect the operating system. Network Penetration Testing The scanner is helpful for quick port scans but also for lengthy scans which can take multiple hours. ...
The scans can be scheduled for any hour during the day. Port scans are then queued on that hour, and will run in sequence. If you scheduled 20 scans for 13:00 UTC they will not all run simultaneously right on 13:00, they will be queued at 13:00 and run as scan servers are availa...
This online port scanner allows testing of open ports and firewalls. With Nmap Online you can scan a single IP address or a range of IPs. Test IPv4 or IPv6.
top-ports"number"扫描开放概率最高的number个端口,出现的概率需要参考nmap-services文件,ubuntu中该文件位于/usr/share/nmap.nmap默认扫前1000个--port-ratio"ratio"扫描指定频率以上的端口服务版本识别-sV 开放版本探测,可以直接使用-A同时打开操作系统探测和版本探测--version-intensity"level"设置版本扫描强度,强度...
Traceroutes are performed post-scan using information from the scan results to determine the port and protocol most likely to reach the target. It works with all scan types except connect scans (-sT) and idle scans (-sI). All traces use Nmap's dynamic timing model and are performed in ...
-sN/sF/sX: 指定使用TCP Null, FIN, and Xmas scans秘密扫描方式来协助探测对方的TCP端口状态 -sS/sT/sA/sW/sM:指定使用 TCP SYN/Connect()/ACK/Window/Maimon scans的方式来对目标主机进行扫描 -sU: 指定使用UDP扫描方式确定目标主机的UDP端口状况 -sP: Ping扫描 快速发现网络 -sR:PRC扫描 定位PRC,对成功...
