Android SDK 国内镜像及配置方法(2025最新，包好使！) android sdk 国内镜像配置方法，纯小白避坑指南，2025最新，亲测包好使！还有包奉上！阅读详情

最近需要用ACE来写实现ping功能的程序，不知如何入手。请各位达人帮忙。
我看了ACE自带的例子，它需要一个ping的服务端才可以实现，我想写一个不需要服务端的。就像win下的ping 一样。
先谢谢各位。

可以使用ACE_ICMP_Socket。自己仔细看看。

ping 是一个很简单的命令，
目标收到这么一个 icmp 包自然会回复你需要的，
不需要服务端。

这个是在 TCP/IP 协议中规定的。

ping会有什么服务端,用raw socket收发icmp包就行了。

ACE好像没有原始socket的

谢谢各位，但是不是我要的。 C的不好移植到我的系统中去。因为我的系统基于ACE 。只想用ACE库来实现这一ping 。达人继续。我会给分的，放心拉。

请教！用ACE库写ping程序
