Linux DDOS and CC attack SolutionBackgroundNowadays, DDOS attacks are becoming more and more frequent. DDOS Denial-of-Service can be implemented without any technology. Some webmasters often report mysql 1040 errors on their websites, and their online users are less than one thousand, mysql configuration is fine. Gener

Recently, the server has been frequently attacked by DDoS, so it can only be solved temporarily by IP source. IP is not the source of changeable, light by hand to add is simply a nightmare, think of a method, with the shell to do.Relatively simple, but very useful:) The following content according to the author's original text to make appropriate changes:)1.

Anti-DDoS: CC attack defense system deployment1. System effect this DDOS Application Layer defense system has been deployed on the http://www.yfdc.org site (if access fails, please directly access the server in China http: // 121.42.45.55 for online testing ). The defense system is at the application layer, which effectively prevents the abuse of server resources
After a series of recent retaliatory attacks caused by the closure of the file sharing website Megaupload, Anonymous's Denial-of-Service "Cannon" has greatly reduced the number of shells fired later.
Although Anonymous members intend to break the INTERPOL website in February 28 (mainly through the online version of the "low-track Ionic Gun" Denial-of-Service tool ), moreover, some vulnerable websites (including most recently websites affiliated with
