python———scapy库（数据包发送）

Scapy的是⼀个强⼤的交互式数据包处理程序（使⽤python编写）。它能够伪造或者解码⼤量的⽹络协议数据包，能够发送、捕捉、匹配

请求和回复包等等。它可以很容易地处理⼀些典型操作，⽐如端⼝扫描，tracerouting，探测，单元测试，攻击或⽹络发现（可替代

hping，NMAP，arpspoof，ARP-SK，arping，tcpdump，tethereal，P0F等）。最重要的他还有很多更优秀的特性——发送⽆效数据

帧、注⼊修改的802.11数据帧、在WEP上解码加密通道（VOIP）、ARP缓存攻击（VLAN）等，这也是其他⼯具⽆法处理完成的。
