Denial of Service (DoS) and Distributed Denial of Service (DDoS) have become one of the greatest threats to network security. How to defend against DDoS attacks is currently a hot topic. However, the current defense mechanism barely monitors DDoS attacks in real time. This paper describes a
monitoring | design
Summary: This paper presents a real-time monitoring system based on OS kernel service and multithread technology, which solves the problem that the previous monitoring system can not recover the abnormal webpage in time. The Transmission control part and monitoring part of the system are introduced emphatically.
Key Words:
the modification: When the new interface appears, there is no hint or feedback in the field of vision.
Figure 8: After the modification: when the new interface is ready to load, the system responds, but does not interfere with the process through an automatic response.
Instance: framework Template
The display layout frame indicates that you are going to jump to the new interface and switch the layout ahead to fill the blanks. There is also a benefit that makes the program look more "respon

In fact, this is the function of rsync, he will only output a difference need to sync the file information. Do not believe you to take this line of Rsync run to try.

First of all, the introduction of Rsync and INotify, are found on the Internet information. First of all, the following rsync and inotify introduction is not my own writing.

Recently need to implement a dynamic backup of the files on the server, I do not want to do a manual backup every time, find a lot of information on the Internet, found that using rsync can be achieved, if you want to achieve real-time synchronization, you can also use the rsync+inotify combination, this article is don
regular data mirroring. With the scale of application system expanding, the data security and reliability also put forward higher requirements, rsync in the high-end business system also gradually exposed its shortcomings. First, when rsync synchronizes data, it needs to scan all the files before doing the comparison, then the difference is transmitted. If the number of files reaches millions or even tens, scanning so the file will be very time consu
Inotify: An efficient, real-time Linux file System event Monitoring Framework Overview-Why do I need to monitor the file system?In daily work, people often need to know that there are changes in some files (clips), such as:

Second, the first knowledge inotify
Inotify is a powerful, fine-grained, asynchronous file system event monitoring mechanism, the Linux kernel from 2.6.13, joined the Inotify support, through the Inotify can monitor the file system to add, delete, modify, move and so on

The increasing development and popularization of computer network technology provides a global high-speed channel for information sharing. However, the current TCP/IP protocol family has potential security vulnerabilities, and its security mechanism is not sound, how to protect the resources and information in the enterprise's internal network from being arbitrarily damaged or stolen by external attackers is an important issue for enterprise network security. When we are worried about hacking or
