下面开始构造HTTP数据包，

IP层和TCP层使用python的Impacket库，http内容自行填写。

复制代码 代码如下:

#!/usr/bin/env python

#-------------------------------------------------------------------------------

# Name: raw_http.py

# Purpose: construct a raw http get packet

import sys

import socket

from impacket import ImpactDecoder, ImpactPacket

def main():

if len(sys.argv) < 3:

print "Use: %s <src ip> <dst ip>" % sys.argv[0]

print "Use: %s <src ip> <dst ip> <cnt>" % sys.argv[0]

sys.exit(1)

elif len(sys.argv) == 3:

src = sys.argv[1]

dst = sys.argv[2]

cnt = 1

elif len(sys.argv) ==4:

src = sys.argv[1]

dst = sys.argv[2]

cnt = sys.argv[3]

else:

print "Input error!"

sys.exit(1)

#print src, dst

ip = ImpactPacket.IP()

ip.set_ip_src(src)

ip.set_ip_dst(dst)

# Create a new ICMP packet of type ECHO.

icmp = ImpactPacket.ICMP()

tcp = ImpactPacket.TCP()

tcp.set_th_sport(55968)

tcp.set_th_dport(80)

tcp.set_th_seq(1)

tcp.set_th_ack(1)

tcp.set_th_flags(0x18)

tcp.set_th_win(64)

tcp.contains( ImpactPacket.Data("GET /att/DIYLife/41264/528 HTTP/1.1rnHost: 192.168.111.1rnAccept-Encoding: identityrnrn"))

ip.contains(tcp)

# Open a raw socket. Special permissions are usually required.

s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_TCP)

s.setsockopt(socket.IPPROTO_IP, socket.IP_HDRINCL, 1)

seq_id = 0

while cnt >= 1:

# Calculate its checksum.

seq_id = seq_id + 1

tcp.set_th_seq(seq_id)

tcp.calculate_checksum()

# Send it to the target host.

s.sendto(ip.get_packet(), (dst,80))

cnt= cnt -1

if __name__ == '__main__':

main()

运行后抓包如下：
