获取目标ip/活动udp连接的端口? [英] Get Destination Ip/Port of active udp Connection?
问题描述
我能够使用iphlpapi检索活动的TCP和UDP连接. TCP连接显示源信息(ip/端口)，目标信息(ip/端口)，状态和进程ID. 但是对于UDP连接，它没有提供远程IP和端口.那就是我想要得到的. 在Delphi或c ++中使用源信息或进程ID获取目标信息的任何方法.

But for UDP Connection its no giving remote IP and port. That what i want to get. Any way to get destination information using source information or process id in Delphi or c++.
推荐答案
UDP是无连接协议.您只能获取已打开的本地端口.
UDP is a connectionless protocol. You can only get the local port that has been opened.
更新: 这适用于静态查看端口使用情况.但是，如果您有活动的UDP流量，您仍然可以检索远程端点.
UPDATE: This applies for a static look at the port usage. However, if you have active UDP trafic you can still retrieve the remote endpoint.
用户Ishmeet在评论中建议使用uIP或LwIP.
