the stand-alone mode, xinted mode is also called Internetsuper-server (Super Server). XINETD can listen to multiple specified ports at the same time, when accepting user requests, he can initiate different network service processes to handle these user requests depending on the port requested by the user. You can think of xinetd as a Management server that manages the startup service, decides to hand over a client request to that program, and then in

xinetd. For example: To start the Auth service, open the/etc/xinetd.d/auth profile, change the "Disable=no", and save the exit.Run/etc/rc.d/init.d/xinetd restartTo stop the Auth service, open the/etc/xinetd.d/auth configuration file, change the "Disable=yes", and save the exit.Run/etc/rc.d/init.d/xinetd restart3.

Management of I/O Ports and I/O memory in Linux Port is the address of the register that can be directly accessed by the CPU in the interface circuit. Almost every type of peripherals is performed by reading and writing registers on the device. The CPU sends commands to registers in the interface circuit through these addresses to read the status and transmit data. A peripheral register, also known as an "I/O port", usually includes three categories:

Associating processes and ports is a very useful function. You can clearly know which programs are using which ports are helpful for trojan detection and removal. However, although we can use the task manager to browse the process list and use Netstat to view the port usage, no command can be directly associated with the process and port WinXP to add the new NetStat function, allows you to directly view the

market. If the network administrator finds this need, they can also configure one to prevent the problem. In practice, we often connect the serial port of our laptop to the secondary port of the router through a dedicated configuration connection line for router configuration and maintenance. Tip 2: Use the Auxiliary port as an asynchronous serial interface On Some routers, do you have to configure asynchronous serial interfaces. In this case, the network administrator needs to configure the Au
