By default, many windows ports are open. When you access the Internet, network viruses and hackers can connect to your computer through these ports. To change your system to a copper wall, close these ports. Next we will introduce how to disable these Network Ports in WINXP/2000/2003: Step 1, click "start" menu/setting

[Editor's note: if we find that the network is disconnected on weekdays, we will use the ping command to see what went wrong. However, many hackers are using the ping command to see which computers are suitable for BOTs .]As campus networks become more and more popular, and users have improved their awareness of network knowledge, many people download some hacking tools online or use Ping commands to scan ports and IP addresses to find bots, it has a

The 1-gigabit layer-3 switch is quite common, so I have studied the 1-gigabit layer-3 Switch with high port flexibility. Here I will share it with you and hope it will be useful to you. After the success of the Gigabit center switch gmt7324, NETGEAR recently launched a more advanced layer-3 gmt7312 switch with more flexible port configurations. GSM7312 provides advanced features such as GSM7324's rich layer-2 switching, layer-3 routing, and QoS of service quality management. It has the same soft

There were few problems when publishing Web sites on IIS, because the ports are configured on their own, but recently encountered such a problem, less nonsense, see Pictures: After the launch of the site, can not start, when the error, prompting the process can not access.

To monitor the performance of mysqlserver, it is estimated that many people use the mysql-cacti-templates template in cacti, but its default configuration only supports monitoring of the standard mysql3306 port. In fact, its script supports multiple ports, but the configuration in the template is not supported by default. The script parameters are as follows: Usage: phpss_get_mysql_stats To monitor the performance of mysql server, it is estimated that

I/O Completion Ports I/O Completion Ports are the mechanisms by which an application uses a pool of threads that was created when the application was started to process asynchronous I/O requests. these threads are created for the sole purpose of processing I/O requests. applications that process logs concurrent asynchronous I/O requests can do so more quickly and efficiently by using I/O Completion

1. The server has 65,535 ports, which is the variable that records the server port, is two bytes and is a short int. Its two-byte storage space determines that it can only open 65535 ports.2. What is the port for? The port is used to listen for TCP connections. That is, the client HTTP connection is communicated using the IP address + server port number.3. That the client comes in HTTP connection request, w

Reprinted from: https://linux.cn/article-4243-1.htmlIf you want to provide services on the server, Enterprise Linux distributions such as CentOS or Rhel contain built-in powerful firewalls, which are strictly the default firewall rules. Therefore, if you install any custom services (such as Web servers, NFS, and Samba), then their traffic is likely to be blocked by firewall rules. So you need to open the necessary ports on the firewall to allow traffi

Environment: Tomcat7.0.55Tomcat to build multiple sites with different IP ports Tomcat is used in the development environment, but sometimes also in production environments. In a production environment, you will encounter multiple sites that need to be placed under one tomcat. Sometimes it is also necessary to open multiple different ports at the same time to accept multiple domain name requests. Typic
