Python端口侦听器

[英]Python Port Listener

原文 2012-08-12 02:40:10 2 2 python

I would like to code a Python program that listens on a range of ports for incoming sin requests (possibly ack and fin as well). 我想编写一个Python程序，该程序在一定范围的端口上侦听传入的sin请求（也可能是ack和fin）。 I then want this program to log the time, ip, and port of these sent packets. 然后，我希望该程序记录这些已发送数据包的时间，ip和端口。

Only thing is I really don't know where to start. 唯一的事情是我真的不知道从哪里开始。 I don't want anyone to hold my hand here, but I do need someone to point me in the right direction 我不想有人在这里牵着我的手，但我确实需要有人将我指向正确的方向

You are probably looking for raw sockets, see http://docs.python.org/library/socket.html 您可能正在寻找原始套接字，请参阅http://docs.python.org/library/socket.html

If you just want to capture received packets on a port range and log it, you should probably save yourself the trouble and use Wireshark http://www.wireshark.org/ 如果您只想在端口范围内捕获接收到的数据包并将其记录下来，则可以避免麻烦并使用Wireshark http://www.wireshark.org/

if it is for educational purposes; 如果是出于教育目的； you could use scapy as a network sniffer. 您可以将scapy用作网络嗅探器。 Otherwise just configuring your firewall to log appropriate events might be enough. 否则，仅将防火墙配置为记录适当的事件就足够了。
