Today's network is very developed, many users are very concerned about the use of network traffic, especially the use of wireless network is more so. However, as with the previous Win7 64-bit flagship version there is no small difference, so many people do not know the new WIN8 system

What should I do under the command line? Obviously there are some methods. For example, ifconfig will have such output:RX Bytes: 1224128649 (1.1 Gib) TX Bytes: 34114947 (32.5 MIB) After a w

The dev Displays the network interface information, Edev displays statistics about network errors, NFS Statistics active NFS Client information, NFSD statistics Server for NFS, sock displays socket information, all shows all 5 switches. They can be used alone o

Sometimes we need a more real-time view of the network card traffic on the server, here I wrote two small script, one with the shell (first, only one network card can be viewed at a time), another in Python (after writing, can view more than one

When the application is running, we can use the following method to view the port traffic information of the hca nic: 1) Clear the status of the port in use. Assume that the port is port1.# Cd/proc/IBA/mt23108/1/port1/# Echo> stats2) run the application3) Check the status of port1 and run the following command:# Cat/proc/IBA/mt23108/1/port1/statsOr directly use the command "p1stats" In addition, we can

In a class Linux system, 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 u

Nload is a very useful traffic monitoring tool with powerful functions. it can monitor network card traffic in real time, including Incoming and Outgoing, that is, inbound and outbound traffic CentOS. NloadIt is a very useful traffic monitoring tool with powerful functions.

　　[It168]As we all know, at the beginning of the Internet, colleges and research institutions communicate with each other, and there is no consideration or design for network traffic control. The principle of IP protocol is to serve all data streams as well as possible, different data streams are equal. However, many years of practice show that this principle is not the most ideal, and some data streams sho

Ntopng Introduction:Ntopng is the original ntop next-generation version for real-time network traffic monitoring display. Ntopng is similar to the RMON Remote network Monitoring agent, with built-in Web service capabilities that use the Redis key value service to store statistics on a time series basis. You can install Ntopng on any designated monitoring server,

The first step:because the process information is not available in NDIS, you can get the information to the portmaintains a table locally on the TDI, storing the correspondence between processes and ports. (Getting process information and ports is not difficult, I've done it, just need to correlate)Step Two:NDIS uses functions to query the TDI for this process and port table, and then to limit the traffic information for a port (difficulty: Figuring o
