The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.In addition, As Zhang Xiaobo said, On the front line at that time, Wearing or not wearing a helmet is a "choice", Because Vietnam is located in Southeast Asia, The climate is hot and humid, Helmets are heavy and airtight, Wearing it is very easy to cause heatstroke, Particularly in fast maneuvers, This is the easiest way to do strenuous activities such as running. Therefore, in order for the troops to fight more efficiently, There would be no mandatory order for everyone to wear a helmet, If you don't want to wear it, you can choose to wear a cloth cap with eaves. So in the vast majority of relevant historical photos, Among our troops participating in the war, The highest percentage of helmets is worn by artillery, It is mainly used to defend the fragments of enemy artillery and various hard objects brought up by explosions in artillery warfare. Even some border militiamen wore helmets in large numbers, On the contrary, the impact is at the forefront, Infantry units carrying out a large number of mobile combat missions are rarely worn, Investigate its reason, It is for the infantry troops to carry out large-scale interspersed operations frequently. Exercise is enormous, It is really inconvenient to wear helmets, This approach has both advantages and disadvantages, It is not good to judge right or wrong here, but when facing such a horrible "killer bee" on the ground on 149, it is regrettable and regrettable that the heavy casualties caused by the low wearing rate of helmets have to be said. If they had worn helmets instead of military caps like Zhang Xiaobo, the casualties caused by the sting attack of "killer bee" would have been much smaller.一对年轻夫妇4岁的儿子被谋杀，他们努力进行着曲折而又艰难的斗争，想要找到逍遥法外的凶手。幸福家园四号楼三单元201、202和三单元的门头房里，盘踞着老马家爷孙四口，每个人都有自己心中向往的桃花源。爷爷马天明希望攒更多养老钱，给窝囊废孙子孙女婿一条后路；孙子马岱想靠自由职业程序员之路，永远大门不出却衣食无忧；姐夫范程远梦想走出家门，成为知名学者；姐姐马桃想要让企业做大做强，创业合力电器…日子一天天过去，每个人都在一本正经地与自己的心愿背道而驰…加上爷爷推拿馆的徒弟金大海、求合租的淘宝主播彭薇薇、楼上楼下形色各异的邻居们，回迁房小区里，上演着一宅家族最普通的琐碎日常，却也是最令人向往的生生不息……5.
