请教！用ACE库写ping程序

[lwqcny]

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。

[lwqcny]

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。

[xlsue]

ACE好像没有原始socket的

[qgw_2000]

ping会有什么服务端,用raw socket收发icmp包就行了。

[jixingzhong]

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。

可以使用ACE_ICMP_Socket。自己仔细看看。
