Alarm systemThe SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.故事发生在上个世纪50年代末至本世纪初，讲述的是北京广播专科学校女大学生文艺秋与同学万声、同事宋绍山、苏联功勋播音员卡佳等人之间的曲折爱情故事。由于特殊的时代背景，这段跨国恋纠缠了几十年，主人公之间历经着离别、相思、等待、重逢等重重磨难，但是每一个人都没有放弃对于爱情的执着与追求。在杂志社担任专栏记者的女主在发现她的男票劈腿她的同事兼好友，并且厚着脸皮来跟她求和后，为躲开痴缠的前男票，伤心地跟闺蜜一起去东京旅行。在东京的黑帮混乱中被黑帮老大的男主小劫持了下，的女主把男主带回酒店帮他包扎伤口。两人在东京小吵小闹地度过愉快的一周后，在新年那天男主不辞而别.2个月后女主在泰国再次与男主不期而遇，女主采访了此时身份为成功商人的男主。接着就是言情小说里霸道总裁爱上小白兔的经典剧情和桥段了。男二是白虎帮的老大.警校毕业的优秀生何睦,以卧底方式将走私枪支的在押人员“老枪”救出,找到藏匿枪支的地点，却没想到被前来买枪的“海子”认出，随后被“老枪”等人劫持；逮捕过“老枪”的老刑警袁大志凭借自己的足智多谋及何睦的里应外合，终将“老枪”等人绳之以法……该剧以刑侦小组办案为主线,以幽默诙谐的风格充分展现了新时期年轻刑警的风采与魅力，情节曲折离奇，惊心动魄又悲喜交集。《寻找喜剧人》无缝接档《欢乐喜剧人》第五季，16组喜剧人将通过舞台竞演模式争夺《欢乐喜剧人》第六季认证席位。
