socket programming in C + multiple socket, same port num

[boddah]

Hi all,
I was trying to create 2 sockets to be able to establish 2 connections to a client. The first socket supposedly to facilitate the DH algo which I wanted to implement and the second socket to only accept byte streams as input. I always get "unable to bind" even though I've used the close() and shutdown() function to close the first socket. Can anyone help show me the way here?

Ususally shutdown shuld be called from server side and close from client side.
As u cal shutdown you shuld be able to use the same port.

Yes Raghul, I'm aware of that. But still I'm unable to bind the socket to the port.

After calling shutdown tru to run netstat and see whether the port is released or some other process is using that port.

After creating the 1st socket, a client successfully connects to it and closed its connection. When the server tries to bind for the second socket, it fails and the app exits. Hence, the 2nd client unable to connect. Any way i can solve this?

Hi,
i am getting ur question.
Usually after shutdown this behaviour dosent happen.
So to understand whats happenening after running the first application run netstat and see whats happening to the port or somebody is using it.

Then run the second program if the port is not used by any body.

I'm quite new to the use of sockets but I think this might have to do with the "TIME-WAIT" state (which often takes up to 4 minutes, and is there to deal with wandering packages etc.)
