Its biggest advantage is that it will be started all the time. when the outside world has requirements, the corresponding speed is faster, such as httpd and other processes; www.2cto.com Super daemon process: when the system starts, a unified daemon, xinet, is responsible for managing some processes. when a request arrives, it must be transferred through xinet to wake up the processes managed by xinet. Only the xinet daemon occupies system resources, and other internal services do not occupy system resources. only when data packets arrive will the xinet administrator wake up. In addition, we can also use xinet to set some access permissions for the processes it manages, which is equivalent to an additional management mechanism.
