Basically you want a keep-alive signal?

Do you have the server source? If you do, you could create a linked-link and hold the times in there, checking every once in a while...

Do you have the client source? You can do the same in it really...

With the points you've listed above, you must consider this a very difficult problem, so I'm probably missing the whole picture. Would you be more detailed please?

How are you keeping track of the clients, and which IO strategy are you using  ? Asynchronous ? blocking ? or event based ? completion ports ?.

Depending on that it might be trivial or a bit difficult to implement what you are trying to do. You need to keep track of in-active time for each client, after it hits a threshold send a signal to the client and reset the in-active time (if the need be). This would be easily accomplished in non-blocking modes.

>> how to find out the port is ideal for some time?

What eactly do you mean by that ?

Dear srinivasanmr

I think you forgot this question. I will ask Community Support to close it unless you finalize it within 7 days. You can always request to keep this question open. But remember, experts can only help you if you provide feedback to their questions.
Unless there is objection or further activity,  I will suggest to

     "PAQ at zero points"

since you never gave more feedback.

PLEASE DO NOT ACCEPT THIS COMMENT AS AN ANSWER!
