问题描述
是否有一个实现独立TCP堆栈的python库?
Is there a python library which implements a standalone TCP stack?
我无法使用通常的python套接字库，因为我正在通过套接字接收数据包流(它们正在通过此套接字传送给我).当我收到发送到特定端口的TCP SYN数据包时，我想接受连接(发送一个syn-ack)，然后获取另一端发送的数据(适当的确认).
I can't use the usual python socket library because I'm receiving a stream of packets over a socket (they are being tunneled to me over this socket). When I receive a TCP SYN packet addressed to a particular port, I'd like to accept the connection (send a syn-ack) and then get the data sent by the other end (ack'ing appropriately).
我希望已经编写了某种可以利用的TCP堆栈.有任何想法吗?过去，我曾在C项目中使用过lwip －在python中遵循这些原则是很完美的.
I was hoping there was some sort of TCP stack already written which I could utilize. Any ideas? I've used lwip in the past for a C project -- something along those lines in python would be perfect.
推荐答案
您没有说您正在使用哪个平台，但是如果您正在使用linux，我会打开调整/点击接口并获取IP数据包作为真正的网络接口进入内核，因此内核可以完成所有棘手的TCP任务.
You don't say which platform you are working on, but if you are working on linux, I'd open a tun/tap interface and get the IP packets back into the kernel as a real network interface so the kernel can do all that tricky TCP stuff.
(例如) OpenVPN 的工作方式-它接收原始IP数据包UDP或TCP，然后通过tun/tap接口将它们通过隧道传输回内核.
This is how (for example) OpenVPN works - it receives the raw IP packets over UDP or TCP and tunnels them back into the kernel over a tun/tap interface.
我认为现在Windows也有一个tun/tap接口，它是为Windows的OpenVPN端口开发的.
I think that there is a tun/tap interface for windows too now which was developed for the OpenVPN port to windows.
