However, SYN flooding is very different from other TCP spoofing attacks. SYN flooding attacks the services of the new connection without affecting the established connection, while other spoofing attacks break the established connection and cannot block the new connection from the beginning. SYN attacks can be stopped only by modifying the initial handshake program, while other spoofing attacks require checking every piece of data throughout the connection life cycle. What SYN flooding and other TCP spoofing attacks have in common is that they all depend on the attacker's ability to send IP packets that disguise the source address, while the same way to defend them is to deploy more address filtering or use IP Security Protocol (IPsec).陈启坐在一边，他早就和何薇没有一点瓜葛，叶琳琳的话只会让他感到好笑，但是林白的表现，却让他有些感动。尹旭淡淡道：汉王一片美意寡人心领了，想来那位吕伊小姐才不过十四五岁的年纪，尚且年幼啊。希望渺茫，不服输的麦昆能否重新取得胜利的荣光……大明洪武年间，少年马和从云南被征入宫为太监，分到燕王府当随从。燕王朱棣胸有大志，在守边岁月中经受了磨炼，尤其结识高僧姚广孝后，更是开阔了胸襟。他与父皇朱元璋的海禁政策越来越不合拍。在跟随朱棣守卫北平和边陲的日子里，马和逐步成长起来，其良好的素质，为以后的建功立业打下了基础。皇长孙朱允炆君临天下，为巩固皇权开始削藩，燕王朱棣首当其冲。为了生存，朱棣被迫装疯，饱受屈辱。郑和的结拜姐姐宋莲芯，也被奸臣所谋。朱棣在绝境中毅然率领八百壮士起兵，展开了争夺皇位的“靖难”之役。战争中，马和与姚广孝、张玉等人一样功勋卓著，尤其在郑村坝一役，他奋勇救朱棣于危难，从此更被燕王视为心腹。朱棣开元登基后，为洗清自己的“篡逆”之名，决心直追汉武唐宗，开创一代盛世。登基之初，他赐马和姓“郑”，随之，悄然改变朱元璋的禁海国策，任命35岁的郑和为统率大明宝船队下西洋的钦差总兵官。永乐三年(1405年)7月11日，郑和率二万七千八百余人，从南京、太仓一带至福建长乐太平港扬帆出海。庞大的大明船队，从此开始长达28年的海外宣这种性格，真得可以和杨过擦出火花，以至于演绎出一场生死绝恋？很多人表示怀疑。
