based on Windowssocket in the Windows environment. Windows Sockets provides two different IP multicast implementations: Windows Sockets provides two different ways to implement IP multicast: Winsock1 and Winsock2. The VC 6.0 development tool is implemented in Windows2000 platform, and the programming of multicast communication based on Winsock2 is realized in this system.Send side (front end, client) implementation steps:(1) Load the Winsock2 library

multiple CPUs, this parameter can display the CPU status on demand, for example:-C 0,1 is the information that displays cpu0 and CPU1.-D: Displays the disk read and write data size.-D hda,total:include hda and total.-N: Displays the network status.-N eth1,total: Specifies the network card to display when there are multiple NICs.-L: Displays system load conditions.-M: Displays memory usage.-G: Displays the

The Linux system administrator should know the monitoring tool. if you want to monitor the performance of the Linux server, try the built-in shell commands and some additional tools. Many Linux distributions have tons of monitoring tools. These tools provide measurable information for observing the activities of the system and finding the resulting system... The

to locate the problem? Atop Introduction Atop is a tool used to monitor Linux system resources and processes. It records the running status of the system at a certain frequency, the collected data includes the usage of system resources (CPU, memory, disk, and network) and the running status of processes, and can be saved to the disk as a log file. When a server encounters a problem, we can obtain th

In Unix-like systems, you can use top to view information such as system resources, processes, memory consumption, and so on. View network status You can use Netstat, nmap and other tools. To see real-time network traffic, monitor TCP/IP connectivity, and so on, you can use Iftop.What is Iftop?The iftop is a real-time traffic monitoring
