Network, closing socket... timewait.

Ok, I have a tinsy problem.

I am trying to interact with an existing server (I have NO CONTROL over the server)  it is a temporary tcp stream connection, only meant to send and receive a single command (think of it like a web server, but it isn't)

Now, I need to get an update from this server once every second (sometimes even more frequently).

My problem is, this is what is showing up in my netstat...

tcp        0      0 localhost.localdo:34373 localhost.localdo:20000 TIME_WAIT
tcp        0      0 localhost.localdo:34372 localhost.localdo:20000 TIME_WAIT
tcp        0      0 localhost.localdo:34375 localhost.localdo:20000 TIME_WAIT
tcp        0      0 localhost.localdo:34374 localhost.localdo:20000 TIME_WAIT
tcp        0      0 localhost.localdo:34369 localhost.localdo:20000 TIME_WAIT

And this goes on and on and on.

I am closing my end of the connection, and I'm fairly sure the server is closing its end of the connection.  What can I do to prevent this time wait issue?

Here is the meat of the section of code that might be causing the problem.

I am sending the request.  I am then waiting for a response (up to a certain period) (check sock does a select to see if there is data to be read) then I am returning the results.

do {
                Invalid = CheckSocket(sock);
                Counter++;
        } while ((Counter<5) && (Invalid == 1));

        if (Invalid)
                sprintf(IBuffer,"Server is Busy, please try again later.\n");
        else
        if (read(sock, IBuffer,( sizeof(unsigned char)*FEEDBACK_BUFFER_LENGTH))
< 0) {
                perror("receiveing on stream socket");
                close(sock);
                exit(1);
        }

        //*********************************************************************
        //      Close this connection, since the stream isn't persistent
        //*********************************************************************
        close(sock);

Now, my program is operating normally, but those TIME_WAIT's are stacking up.  is there any way to not have those happen, or to reduce the length of time of the wait so it won't stack up so fast?
