Linux traffic monitoring tool usage Summary-iftop allows you to use top in Unix-like systems to view system resources, processes, memory usage, and other information. To view the network status, you can use tools such as netstat and nmap. To view real-time network traffic and monitor TCP/IP connections, you can use iftop. I. What is iftop? Iftop is a real-time

host, press p to toggle to show port information, toggle to suspend/resume display by P, toggle to show average flow graph bar by B; Press B to calculate the average flow rate of 2 seconds or 10 seconds or 40 seconds; press T to toggle whether the total flow of each connection is displayed; Press L to turn on screen filtering, enter the characters to filter, such as IP, press ENTER, the screen will only display this IP-related traffic information, pr

Linux View network traffic Below the GUI, there is a lot of tools to show network traffic, so what to do under the command line.It is obvious that there are, for example, Ifconfig, there will be such output:RX bytes:1224128649 (1.1 GiB) TX bytes:34114947 (32.5 MiB)After a while, the values change, and the difference between the two is the amount of

Installing Darkstat in Linux: web-based traffic analyzer Darkstat is a simple web-based traffic analysis program. It can work on mainstream operating systems such as Linux, Solaris, MAC, and AIX. It continues to work in the background as a daemon, constantly sniffing network data, and displaying it on its webpage in a

Because many VPS or server are limited traffic, but many service providers do not provide a detailed flow chart, such as daily traffic table, so it is certain that some people would like to know how much traffic on their servers.Vnstat is a very useful server traffic statistics command. I'll get a few pictures to show

The Semget (), Semctl (), Semop () and its basic experiments of signal traffic This signal is not easy to understand, ah, I read the book several times before I know what is going on. In this section of the signal before, I still want to say a few small knowledge points, this is my final understanding after learning the "essence", haha! What does the semaphore do? Semaphore is a kind of interprocess communication mechanism to solve the problem of s

TC is very powerful ah, a lot of so-called hardware routers, are based on this.TC IntroductionIn Linux, TC has two control methods CBQ and HTB.HTB are designed to replace CBQ. It is a hierarchical filtering framework. TC consists of three basic constituent blocks: Queue rules Qdisc (queueing discipline), Class (classes), and classifiers (classifiers)Queue (queueing discipline): Used to control the network transmit and receive speed. With queues,
