pkt.summary() 显示一个一行的报文摘要
|
>>> a[0].summary() ‘Ether / IP / TCP 172.31.100.222:ssh > 172.31.100.149:57386 PA / Raw’ |
pkt.show() 按照层次显示报文内容
|
>>> a[0].show() [ Ethernet ] dst= a0:1d:48:b3:80:83 src= 00:0c:29:ac:89:2f type= 0x800 [ IP ] version= 4L ihl= 5L tos= 0x10 len= 92 id= 4551 flags= DF frag= 0L ttl= 64 proto= tcp chksum= 0x713 src= 172.31.100.222 dst= 172.31.100.149 \options\ [ TCP ] sport= ssh dport= 57386 seq= L ack= dataofs= 5L reserved= 0L flags= PA window= 242 chksum= 0x2201 urgptr= 0 options= [] [ Raw ] load= ‘\x95\xf6\x96q\xe1u\x1ee\x90\xf2\xa6\x97&\x1a\xc3\x96M\xb9[FhAA\x14U\xf6\xa9z\xc3H\xa7o\xd8\x8a\x1e\x07\xb8\xab\xe8\xc7\xce\x94\r\xca*c\xe0\xf9xu\x1f2’ |
pkt.show2() 与show方法类似，但是针对组装好的报文（例如报文的校验和已经计算完毕）
|
>>> a.show2() [ IP ] version= 4L ihl= 5L tos= 0x0 len= 20 id= 1 flags= frag= 0L ttl= 64 proto= hopopt chksum= 0x1d0a src= 111.111.111.111 dst= 127.0.0.1 \options\ |
构造多层数据报文
|
>>> a = Ether()/IP()/TCP() >>> a |
组装报文
|
>>> a = Ether()/IP()/TCP() >>> a >>> str(a) ‘\xff\xff\xff\xff\xff\xff\x00\x00\x00\x00\x00\x00\x08\x00E\x00\x00(\x00\x01\x00\x00@\x06|\xcd\x7f\x00\x00\x01\x7f\x00\x00\x01\x00\x14\x00P\x00\x00\x00\x00\x00\x00\x00\x00P\x02 \x00\x91|\x00\x00’ |

查看报文中某层协议的内容
|
>>> a = Ether()/IP()/TCP() >>> a[IP] |
查看报文的16进制编码：

使用rdpcap读取.cap包
|
>>> a = rdpcap(“/root/server.cap”) >>> a >>> a[TCP] >>> ctr = 0 >>> for tcppacket in a[TCP]: >>> if tcppacket[IP].src == “172.31.100.222”: >>> ctr+=1 >>> ctr 19 |
pkt.command() 显示构建pkt的scapy命令
|
>>> a >>> a.command() “IP(src=’111.111.111.111′)” |
通过指定子网掩码的方式，可以一次指定多个IP
|
>>> a = IP(dst=”172.31.100.0/24″)/ICMP() >>> send(a) WARNING: Mac address to reach destination not found. Using broadcast. …..WARNING: Mac address to reach destination not found. Using broadcast. .WARNING: more Mac address to reach destination not found. Using broadcast. .WARNING: Mac address to reach destination not found. Using broadcast. .WARNING: Mac address to reach destination not found. Using broadcast. .WARNING: more Mac address to reach destination not found.

Using broadcast. .WARNING: more Mac address to reach destination not found. Using broadcast. .WARNING: Mac address to reach destination not found. Using broadcast. .WARNING: Mac address to reach destination not found. Using broadcast. |
|
>>> a = IP(dst=”172.31.100.0/24″)/ICMP() >>> [p for p in a] [ |
也可以通过指定多个IP，多个端口来构建数据包
例如下面的例子一共可以构建4(4src IPs) X 6(6 sports) X 2(2 dports) = 48个报文
|
>>> a = IP(src=”172.31.100.0/30″)/TCP(sport=[(50000,50005)],dport=[80,443]) >>> [p for p in a] [ sport=50000 dport=https |>>, |

conversations()方法可以绘制出网络会话的情况（需要安装对应插件，Kali默认已安装）
>>>a = sniff()
>>>a.conversations()
summary()方法打印所有报文的summary
|
>>> a = sniff() >>> a >>> a.summary() Ether / IP / TCP 172.31.100.222:ssh > 172.31.100.149:57386 PA / Raw Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59163 RA Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59163 RA Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59163 RA Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59164 RA Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59164 RA Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59164 RA Ether / IP / TCP 172.31.100.222:http > 172.31.100.149:59165 RA …… |
nsummary()方法与summary()类似，只不过多打印出报文序号
|

filter()用一个lambda表达式对报文进行过滤（不会对原报文集合进行修改）
|
>>> a = sniff() >>> a >>> b = a[IP].filter(lambda x:x[IP].src==”172.31.100.149″) >>> b >>> c = a[TCP].filter(lambda x:x[TCP].dport==80) >>> c |
