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

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

For more information about Linux technology and applications, use Ubuntu to connect to an isolated island. No practical desktop is an isolated island. With Linux, network communication, file sharing, printing and other functions are much easier to implement than imagined. Using Linux to run a PC only solves half of the problem, because no computer is isolated. F

How to configure point-to-point VPN and linuxvpn on Linux A Traditional VPN (such as OpenVPN and PPTP) is composed of a VPN Server and one or more clients connected to this server. When any two VPN clients communicate with each other, the VPN Server needs to relay the VPN data traffic between them. The problem with such a central radiation VPN topology is that when the number of connected clients increases,

Sharp speed There may be many friends have not heard, not only can speed up Web Access, the official note for the sharp speed (serverspeeder) acceleration software is a ZETATCP acceleration engine software, can play a significant acceleration of the TCP acceleration technology, enhance the stability of vps/server connection, and effectively improve the bandwidth utilization of the server. But a lot of friends are based on Linux system CentOS 6.8, some

Create an iptables file in the/etc/network/if-up.d/directory with the following content:#! /Bin/sh Iptables-restore Add the execution permission to the script:Chmod + x/etc/NET/if-up.d/iptables Modify/etc/sysctl. the conf content is as follows: There are two items not listed above. You can simply add them directly. Other projects mainly remove comments. In fact, you can directly copy the following content to the configuration file:Net. ipv4.ip _ forward = 1 Net. ipv4.conf. all. send_r

installation, this file downloads additional plug-ins and stores them in a hidden encrypted file system. These plug-ins allow attackers to use newly infected servers to attack and infect other websites. In February July, Yandex researchers estimated that the botnet had approximately 1400 infected servers linked to two independent command control servers. Researchers from the independent research company Malware Must Die (MMD) reported earlier this week that Mayhem writers have added the Shellsh

adopted this statement, admittedly, the argument is not important, the key is to facilitate people to understand. So I try to explain it in a different way, essentially the same, just a little bit more verbose.As I have always said, this article will not go to large sections of the analysis of the source code, that is, do not go to the source annotated work, but hope to draw a blueprint on this topic, as before the analysis of OpenVPN and NetFilter.1
