SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.Second, the main differences between the two are as follows:你说，这个折腾劲儿，谁敢沾上去？要是我们这边在议亲，周家死了人，人家不得说是我张家逼死的？泥鳅姑姑忽然怒道：死了好。在我国北方某地国境线上，发生了一起越境敌特被我击毙的案件。公安局侦察科长李欣等奉命赶到现场，他们认定敌人搞的是双线派遣，另一特务已潜入境内。潜入的特务沿途布雷，老魏爷在追捕中触雷负伤。李欣奋不顾身跳崖排雷，跟踪追击敌人。潜入江城的特务，冒充转业军人，化名周英杰，与潜伏特务“紫貂”挂上了钩。“紫貂”通过“熊钟”这个联络工具，控制着代号叫“银狐”的特务康一挺，巧妙地指挥周英杰的活动。“紫貂”通过周英杰，与某国驻我国大使馆以外交官身份出现的间谍取得联系，又通过康一挺，借“八一四”战备工程总工程师夏明非之手，把周英杰安插在该工程当汽车司机。为了搞清敌人活动的来龙去脉，李欣以“安全检查员”身份，深入到“八一四”工程里去。“五一”游园会上，李欣以“上司”身份从康一挺口中知道敌人“上司”的代号叫，“紫貂”，同时知道敌人已把窃听器通过夏明非带到了市委战备工作汇报会上...《与神的约定》讲述为了救活垂死的孩子做出超越世界伦理道德的选择的两对夫妇的人情爱情电视剧。
