At present, the internal LAN of many enterprises has been established, and many have also established the internal MIS System and email server on the basis of the LAN, the system even carries out services with large data traffic, such as on-demand video streaming. How to use it has become a topic of interest. Let's take a look at the specific application instances of Linux

In Linux, IP commands implement part of the functions implemented by most professional routers. The other command TC implements almost another function on professional routers, the remaining functions are all-inclusive. If you run another zebra, the Linux host will be an advanced router, and its speed will no longer depend on the software, however, it depends on your hardware. Although a complete

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 use Iftop.First, Iftop What is it? The iftop is a real-time traffic monitoring tool similar

The network environment of a server in the company is too high. when the server is connected to the source server for download, it runs to 400 M-500 M. in order to control the server, we studied TC. To control traffic. to control it to a small point, do not let this one occupy all the networks. TC is very powerful. many so-called hardware routes... The network environment of a server in the company is too high. when the server is connected to the sou

How to crawl HTTP traffic packets under Linux (Httpry)September 5, 2014 North For some reason you need to sniff HTTP web traffic (that is, HTTP requests and responses). For example, you might test the performance of a Web server, or X-Uy debug a Web application or restful service, or try to resolve a PAC (Proxy auto-configuration) problem, or check for any malici

As we all know, in the beginning of the Internet are all universities and scientific research institutions to communicate with each other, and there is no network traffic control considerations and design, the principle of IP protocol is as good as possible for all data flow services, the different data flow is equal. However, years of practice have shown that this principle is not ideal, some data streams should be given special care, for example, re

Recent work more or less with Linux flow control a bit of a relationship, since a few years ago know have TC such a thing and some understand its principle, I did not move it, because I do not like TC command line, is too cumbersome, iptables command line is also more cumbersome, But the TC command line is more intuitive than the TC command line, which is too technical. Maybe I don't have a deep understanding of the NetFilter framework for the TC fram

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

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.
