In the implementation of select () under Linux operating system, a) will call epollCtl (epfd, opcode, fd, events) to register the events that have been registered in Initiation Dispatcher into Linux system, where fd means Handle and events means Handle events that we are interested in; B) Synchronize the occurrence of a blocked wait registered event by calling the epollWait method. Events on different event sources may occur at the same time. Once an event is triggered, the epollWait method will return. C) Finally, find the associated SelectorKeyImpl object by the event that occurred, set the event that occurred to the ready state, and then put the SelectorKeyImpl into the selectedSet. In this way, we can get the event-ready SelectorKeyImpl collection through the Selector.selectedKeys () method.消防和救护人员的工作，由烈焰火场、暴风水灾，到荒山野岭、高空水底…一般人迴避之处，却往往成為他们奋力救援的地方；险境中，施救者和被救者，生命经已在无形中紧紧相繫。香港电台电视部与香港消防处联手製作的《火速救兵IV》，继续以真实个案為蓝本，改编成十集半小时的电视剧。故事涉及一些近年备受关注的消防事故和议题，包括十号颱风下上山搜救行山人士、大型交通运输事故及旧式工厦防火安全问题等。对於普罗大眾而言，可能很多平日在火海、灾场中救火救人的消防和救护人员，都不过是「无名英雄」。这些在灾场中英勇救人的錚錚铁汉，其实和你我一样有血有肉，在肩负重任的背后，随时隐藏著一些不為人知，但却扣人心弦的动人故事和情感。透过真人真事改编的《火速救兵》剧集，却反映了这些「无名英雄」更為真实、有血有肉的一面。2018年刚好亦是香港消防处成立一百五十周年，新一辑《火速救兵》，正好让大家了解最新的消防资讯，加强防火意识。Since http is based on tcp, You need to complete a three-way handshake to establish a tcp connection before you can start http communication, Therefore, when http flood attacks are carried out, it is not possible to use forged source ip addresses to launch attacks. An attacker will typically use an http proxy server, Not only can the source be hidden from being traced, It also improves attack efficiency-after the attacker connects to the proxy server and sends the request, You can directly disconnect from the proxy server and start connecting to the next proxy server, At this time, the http connection between the proxy server and the target web server is still maintained, and the web server needs to continue to accept and process data. An efficient http flood attack should continuously send http requests for different resources and pages, and request resources that cannot be cached as much as possible (such as keyword search.
