Article Title: Linux server site traffic limit solution. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. #! /Bin/sh # Simple bandwidth limiter- # Change this to your link bandwidth # (For cable modem, DSL links, etc. put the maximal bandwidth you can # Get, not the speed

You can then start Vnstat: Vnstatd-dThis method has a problem, that is, occasionally stop statistical traffic, especially under the CentOS, when the traffic database is large, there will often be bugs, where we recommend the use of source i

Sometimes we need a more real-time view of the network card traffic on the server, here I wrote two small script, one with the shell (first, only one network card can be viewed at a time), another in Python (after writing, can view more than one network card). In the script all use the while true "dead loop", every 10s from "/proc/net/dev" to take a value and calculate 10s within 10s according to the diffe

The main reasons for the large flow of traffic are as follows: Site size (such as portals, network mall, etc.), that is, the site itself needs to visit the volume, view the site's page view value, hits value, daily traffic is very high. Site page design is unreasonable, the page contains large pictures or audio, video files and other documents, resulting in a Web page too large. The website content is ho

HTTP Strict transport Security (HSTs) is a security feature that Web servers use to tell browsers to communicate with them using HTTPS only, rather than using HTTP. This article explains how to enable HSTs on Apache2, Nginx, and LIGHTTPD. Tested on mainstream Web servers: Nginx 1.1.19, Lighttpd 1.4.28, and Apache 2.2.22, the environment is Ubuntu 12.04, Debian 6 7, and CentOS 6, only some of the parameters need to be adjusted Can work on other distributions.What is HTTP strict transmission secu

Currently, many DDoS attackers use php shell to initiate packets and then launch ddos attacks. The cost is very low. Some people say that, if we control thousands of servers to send packets to a ddos system, we can buy them with a few hundred pieces and press on one of my G-port American servers, it's basically seckilling ....... Cry, now this network situation, alasChatting .......The following describes how to change the security settings of linux servers and php to prevent trojans from becomi

Now that Azure traffic manager has a new feature, it's time to look at the relevant content during the weekend, and take a note to summarize this.First 1th, the author does not agree that the traffic

streaming server deployment structure brings up the following issues:1 due to the high cost of the core network, the traffic expense of the source media server is higher;2 Intermediate multistage Streaming Media server increases the end-to-end delay, Reduced user experience;3 backbone network core room is stable, but

, many weather forecasting programs will also generate traffic black spots. Generally, after we set the location, the weather forecasting program will automatically update the data on a regular basis. In order to know the time for updating data, we should disable the automatic update function of the weather forecast program and use manual update control to manually update the program when you need to query the weather conditions, to avoid unnecessary

1. unlimited bandwidth and traffic restriction:That is, Mb is exclusive and the traffic is limited to GB. If the traffic exceeds 2000 GB, another traffic fee is required. 2. limited bandwidth, Unlimited Traffic:That is, 10 m exclusive bandwidth, unlimited traffic. By simple

, you really need to find a solution. Maybe, just like the core idea of e-mail, you can control sending perfectly, but have no control over receiving. if you absorb this idea, you can understand the difficulty of ingress queue traffic control. However, it is only possible. Linux implements a simple flow control by using a non-queue mechanism at the position of ingress. Aside from the disadvantages of the non-queue mechanism over the queue mechanism, t
