First, could you please avoid MIME messages to the list? Please...

Second, I guess you need some book on networking and UNIX system calls.
Killing the server means sending some signal to the process, like SIGINT.
To shut server cleanly, you have to close() socket before exit().
Use signal() to create a handler for a specific signal for that.

AS for the server dying on client closing the connection, I guess this is
more then acceptable behavior. (you are doing fork() upon accepting a
connection, don't you? in this case only child serving the connection will
die).
