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.Move70年代末期，自小在农村长大的杨柿红，和村里的牛旺相爱，后来两人家庭因为彩礼而闹翻，牛旺入赘到了邻村，杨柿红为了和他赌气嫁给了王长安，起初柿红觉得王长安窝囊，但经历了一段时间的生活，杨柿红慢慢成熟了起来，深深的被王长安的儒雅和走出大山的梦想感动，后来王长安因车祸去世，将一整个家留给了杨柿红，杨柿红为了对得起丈夫，也为了将孩子们教育成材走出大山，在煎熬与困苦中独自承担起了责任，一家人就这样艰难的向前走着，虽然有过机会走出大山改变命运，但柿红为了家人，最终还是留了下来，后来小儿子牺牲，柿红唯一一次走出大山却是为了迎回小儿子的骨灰。柿红历尽了悲欢离合的故事，告诉我们留守也是一种勇气，留守也同样高尚和伟大。The second floor is mine"It 's a flying bee, Wings are particularly numerous, He was covered in yellow and black, It is the way yellow and black are arranged in such a way.
