Windows Server 2008 Disables local ports
Windows system By default many ports are open. By shutting down certain ports, you can improve the security of your Windows system to some extent, especially for servers.
The command "Netstat-an" allows you to know which port the system is currently listening on.
On Windows Server 2008 systems, there are two ways to dis
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

The network software is composed of the client and the service side, and the server listens to the specified port to process the received data, and the client sends the data to the server-side listening port, and the data is processed by the server side, then the processing result is returned to the client.so how do we see on Linux what ports we are listening to, and which clients are connecting to my server? first of all we need to know what protocol
Daemon Service Program". The network daemon used by Redhat Linux 9.0 is xinted (eXtended Internet daemon). The xinted mode is also known as the Internet super-server (super server) compared to the stand-alone mode. 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.
