如何在Mac上从Java读写原始IP数据包? [英] How do I read and write raw ip packets from java on a mac?

问题描述

能够发送和接收原始网络数据包的最简单方法是什么.我是否必须编写自己的某些c API的JNI包装，在那种情况下，我要寻找什么API?

What would be the easiest way to be able to send and receive raw network packets. Do I have to write my own JNI wrapping of some c API, and in that case what API am I looking for?

我希望能够做Wireshark所做的事情，即在接口上记录所有传入的数据包，并且还能够发回我自己创建的数据包.我想在Mac上做.

I want to be able to do what wireshark does, i.e. record all incomming packets on an interface, and in addition be able to send back my own created packets. And I want to do it on a mac.
