If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.但他不愿当汉奸，故而出逃以致身陷匪巢，却意外受到匪首之女金山娇的青睐。这个忠肝义胆女强人，给喜来乐的命运带来了巨大的改变，因为喜来乐，她闯皇城、入军营、劫法场，又随其到西安为太后和皇上治病。期间她与已成为喜来乐正室夫人的赛西施发生摩擦，最终由抵触到接受。捣乱的来了。而此时，惨剧的主人公戚继光，却好像已经忘了一切，他在做一件很不耻的事情，不过在这个时代其实也是很正常的事情——进言献媚。不然遇见那死不改的烂货，天天打我，难不成我要去上吊跳河么？黄爷爷说对不对？黄夫子见她警觉失言，微微点头，意味深长地捻须笑道：你不会倒八辈子血霉的。一边说，一边对板栗使眼色放心，侄儿一定不会偏袒。
