拦截来自特定程序或特定端口的TCP数据 [英] Intercept TCP data from a specific program or to a specific port

问题描述

我正在寻找一种捕获TCP通信的方法.这是通过PC软件发送到工业控制的以太网数据.软件工程师不在附近聊天.如果我可以捕获tcp的内容(只是ascii)，那么我可以来回理解代码.

I am looking for a way to capture tcp traffic. This is ethernet data sent to an industrial control by PC software. Software engineer is not around to talk with. If I can capture the tcp stuff (it''s just ascii) I can understand the codes back and forth. Traffic exchanged is very minimal and we control exactly when it is sent/received.

推荐答案

如果只想捕获并查看特定端口上的数据，请使用 Wireshark [ ^ ].或者，如果要创建捕获特定TCP流量的程序，请使用 Winpcap [

If you want to just capture and see the data on a specific port, use Wireshark[^]. Or if you want to create a program that captures specific TCP traffic, use Winpcap[^] library.
