问题描述

谁能告诉我生成UDP，TCP和IP数据包的基本步骤是什么.以及如何使用Python生成它?

Can anyone tell me what is the basic step to generate UDP, TCP and IP Packets. And how can i generate it using Python?

推荐答案

根据jokeysmurf的建议，您可以制作带有鱼尾的数据包

as suggested by jokeysmurf you might craft packets with scapy

如果您要发送/接收普通数据包，则应使用套接字或套接字服务器

if you you want to send/receive usual packets then you should use socket or socketserver

使用以下命令将TCP发送到Google的端口80

to send TCP to google's port 80 use

    import socket
    HOST = 'google.com'    # The remote host
    PORT = 80              # The same port as used by the server
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((HOST, PORT))
    s.send('GET / HTTP/1.1\r\nHost: google.com\r\n\r\n')
    data = s.recv(1024)
    s.close()
    print 'Received', repr(data)

使其变为udp，将SOCK_STREAM更改为SOCK_DGRAM

to make it udp change SOCK_STREAM to SOCK_DGRAM
