Some seemingly unnecessary ports can disclose sensitive information about many operating systems to hackers, such as the IIS services that Windows Server defaults on to tell each other that your operating system is Windows 2000. Port 69 tells the hacker that your operating system is most likely a Linux or Unix system, because 69 is the port used by

The difference between interviewing and talking on the phone is that the interview can immediately know if the other person died (crash, SIGCHLD), and the phone talk can only be judged by the periodic heartbeat to see if the other person is still alive. With these metaphors, the design of distributed systems can take "role playing", and several people in the team play a process in which the role of the person is det

So our communication thread for the Epoll server is enough. The basic
