我有一个Python项目,我需要将简单的TCP SYN消息发送到IPv6地址并使用原始套接字.我的脚本可以无误地执行,但没有发送syn包.我在我的脚本中不确定IPv6标头,TCP标头或IPv6原始套接字出错了.网络配置为IPv6,因此可以排除网络问题.

这是我的脚本,我在RHEL 5上使用Python 2.4:

import socket, sys
from struct import *

# checksum functions needed for calculation checksum
def checksum(msg):
    s = 0
    # loop taking 2 characters at a time
    for i in range(0, len(msg), 2):
        w = (ord(msg[i]) << 8) + (ord(msg[i+1]) )
        s = s + w

    s = (s>>16) + (s & 0xffff);
    s = ~s & 0xffff

    return s

def init_tcp_syn_packet_v6(source_port,dest_port, source_ip, dest_ip):
    packet = '';
    # ip header fields
    version     = 6                       #4 …
