如何编程实现TCP/UDP下面各种端口的disable/enable？

[juqiang]

netbios
wsock2

我都没找到相应的method，大家救命啊！！！

采用ping 方法.

[juqiang]

ping能够disable吗？请痞子兄弟详细说一下吧！

ping????????????????

ping->dos攻击？->TCPIP饯崩溃?

void __fastcall TForm1::Button1Click(TObject *Sender)
{
TServerSocket *Socket = new TServerSocket(this);
FSocketEvent = Socket->Socket->OnSocketEvent;
Socket->Socket->OnSocketEvent = SocketEvent;
Socket->Port = StrToInt(Edit1->Text);
Socket->Open();
ListBox1->Items->AddObject(Edit1->Text, Socket);
}
//---------------------------------------------------------------------------


void __fastcall TForm1::SocketEvent(System::TObject* Sender, TCustomWinSocket* Socket,
TSocketEvent SocketEvent)
{
if (SocketEvent == seLookup)
{
int Reuse = 1;
setsockopt(Socket->SocketHandle, SOL_SOCKET, SO_REUSEADDR,
(char*)&Reuse, sizeof(Reuse));
}
Socket->OnSocketEvent = FSocketEvent;
}

自已去delete那些new的socket啦

上面是TCP的，如果是UDP的话。。。UDP没用过，但道理是一样的，只在reuseaddr就行了，因为Active，发现如果有Port使用的话，会throw，所以做这个是在:
s = socket(...);
setsocktopt(..., SOL_REUSEADDR, ...);

goon socket config...

就这么回事。不清楚的话，看看setsockopt的帮助，：）

呵呵，和我一个哥们说得差不多！就是“占用”这个端口，别人就没法用啦！好了，结账了，谢谢！！！
