Recent work is somewhat related to the Linux flow control. Since I knew about TC a few years ago and more or less understood its principle, I did not move it, because I do not like the TC command line, it is too cumbersome. iptables command line is also more cumbersome, but more intuitive than the TC command line, and the TC command line is too technical.Perhaps I have no understanding of the TC framework for the NetFilter framework. Yes, maybe. Iptab

TC IntroductionIn Linux, TC has two kinds of control methods CBQ and HTB. HTB is designed to replace CBQ. HTB is more flexible than CBQ, but CPU overhead is also greater, and usually high-speed links use CBQ, generally HTB used more broadly. HTB's rules are essentially a tree-like structure, consisting of three basic constituent blocks: The queue specifies Qdisc (queueing discipline), classes (Class), and Classifiers (classifiers).QdiscQueueRules(queu

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
