linux trace network traffic

Http://www.vpser.net/manage/iftop.htmlIn 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

[Blog recommendations] Analysis of the principles of the Linux TC (Traffic Control) Framework This blog post is from the Bkjia blog dog250 blogger. If you have any questions, go to the blog homepage for an interactive discussion!Blog: http://dog250.blog.51cto.com/2466061/1568267 Recently, my work is more or less related to Linux throttling.

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 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 t

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.
