本文主要是利用scapy包编写了一个简易扫描工具,支持ARP、ICMP、TCP、UDP发现扫描,支持TCP SYN、UDP端口扫描,如下:
usage: python scan.py <-p ping扫描类型> <-s 端口发现类型> [-t target] [--port ports]
简单扫描工具,可以进行存活扫描及端口扫描.
存活扫描包括:ARP扫描、ICMP扫描、TCP扫描、UDP扫描.
端口扫描包括:TCP SYN扫描、TCP ACK扫描、TCP FIN扫描.
optional arguments:
-h, --help show this help message and exit
-v, --version show program's version number and exit
target group:
用于设置IP、PORT参数
--target TARGET target为IP或IP段,如192.168.1.1,192.168.1.x,或1
92.168.1.1-254
--port PORT port为待扫描的端口,如21,80,...或21-80
ping group:
用于开启存活扫描相关选项
-p 开启存活扫描
--ARP 启动ARP扫描
--ICMP 启动ICMP扫描
--TCP 启动TCP扫描
--UDP 启动UDP扫描
port scan group:
用于开启端口扫描相关选项
-s 开启端口扫描
--SYN 开启SYN扫描
--ACK 开启ACK扫描
--FIN 开启FIN扫描
--UPORT 开启UDP端口扫描
utils group:
用于开启扫描过程中的一些实用选项
--timeout TIMEOUT 设置发包超时时间,默认0.5秒
--retry RETRY 设置发包重试次数,默认不重试
以上做为说明,祝好运!
一、发现扫描
1.首先进行ARP扫描
python scan.py -p --target 192.168.1.1-254 --ARP
[+]IP: 192.168.1.1 => MAC: 14:75:90:xx:xx:xx
[+]IP: 192.168.1.111 => MAC: c6:36:55:xx:xx:xx
[+]总共耗时9.84091806412秒.
通过retry参数增加发包尝试次数,如下:
python scan.py -p --target 192.168.1.1-254 --ARP --retry 2
[+]IP: 192.168.1.1 => MAC: 14:75:90:xx:xx:xx
[+]IP: 192.168.1.111 => MAC: c6:36:55:xx:xx:xx
[+]IP: 192.168.1.102 => MAC: 58:1f:28:xx:xx:xx
[+]IP: 192.168.1.114 => MAC: 6c:8d:c1:xx:xx:xx
[+]IP: 192.168.1.103 => MAC: 84:38:38:xx:xx:xx
[+]总共耗时20.429942131秒.
2.使用ICMP扫描,若没有指定任何扫描类型参数,默认会启用ICMP扫描,如下:
python scan.py -p --target 192.168.1.1-254
[+]没有指定任何ping扫描方式,默认选择ICMP扫描
[+]IP:主机192.168.1.1 echo-reply.
[+]IP:主机192.168.1.111 echo-reply.
[+]总共耗时10.7177450657秒.
通过timeout参数,设置较长的超时,可以防止网络状况不好造成的丢包,如下:
python scan.py -p --target 192.168.1.1-254 --timeout 2
[+]没有指定任何ping扫描方式,默认选择ICMP扫描
[+]IP:主机192.168.1.1 echo-reply.
[+]IP:主机192.168.1.111 echo-reply.
[+]IP:主机192.168.1.114 echo-reply.
[+]总共耗时10.7566649914秒.
3.使用TCP扫描
python scan.py -p --target 192.168.1.100-120 --TCP --timeout 1

python scan.py --target 192.168.1.110-115 -s --SYN
[+]没有指定任何扫描端口,默认扫描1-1024
[!]扫描... 192.168.1.110
