c# - How to check what connections a given process has created to the internet

Question

I mean, if you use tools like NetLimiter, they let you know that a given process that connections to IP1, IP2, etc. I am using packet sniffing for my application, but I only need to packet sniff one application, so I'd like to know to what ip addresses that application is connected. Any easy way to do this? I am using a wrapper for WinPCap.

edit: After googling I came to know about the -netstat -bno command. It seems to do what I want, but I'd like to know if there are any specific functions do do it. Otherwise, I'll use this.

edit2: w i n d o w s !

Answer 1

正如你所建议的，使用windows等价物；

netstat -abnot 

Answer 2

Take a look at GetExtendedTcpTable(), and it's related listed functions. C or C++, I imagine the VB equivs have similar names if your taste is VB.

如果您在 Linux 上，您可以说“netstat -nap”，它将列出打开的网络和 UNIX 域套接字。

你也可以从 /proc/net/tcp 和 /proc/net/udp 中读取这样的信息。此页面http://linuxdevcenter.com/pub/a/linux/2000/11/16/LinuxAdmin.html应该可以帮助您入门。
