Another advantage is speed. If each of the target port to a linear manner, the use of separate connect () call, it would take a very long time, you can open multiple socket, thus speeding up the scanning. The use of non-blocking I/O allows you to set up a low exhaustion of the time cycle, while observing a number of sockets. But the shortcomings of this method is very easy to be found, and to filter out. The computer logs
