Your client should select the socket for read events.
- as soon as the answer from the server is received, select shall return and you may further process, or
- select shall block until the timeout expires. In this case, you may conclude that the server is possibly not running, and terminate the processing.
Since you're using UDP, you may also want to connect to the server using connect(). On some systems, you'll get possible error (like ICMP "port unreachable"), though asynchronously.
