TCB (TCP? Transport Control Block is a transport protocol data structure that contains all the information of the connection (in fact, in many operating systems, it is a queue used to process inbound connection requests. The queue holds TCP connection items that are in a half-open state and items that have established a full connection but have not yet been extracted by the application through an accept () call). The amount of memory occupied by a single TCB depends on the implementation of TCP options and other functions used in the connection. Usually a TCB has at least 280 bytes, which in some operating systems has exceeded 1300 bytes. The SYN-RECEIVED state of TCP is used to indicate that the connection is only half open, and the legality of the request is still questioned. An important aspect worth noting here is that the size of TCB allocation space depends on the SYN packets received-before the connection is fully established or the return reachability of the connection initiator is verified.

1949年3月5日，中共中央七届二中全会在这里召开。毛泽东在报告中指出：“夺取全国胜利，这只是万里长征走完了第一步。……中国的革命是伟大的，但革命以后的路程更长，工作更伟大，更艰苦。这一点现在就必须向党内讲明白，务必使同志们继续地保持谦虚、谨慎、不骄、不躁的作风，务必使同志们继续地保持艰苦奋斗的作风。”

The plot I remember was said when I hit the master of the object room, that is, when I grabbed the last headband.
In the above figure, when deleting the corresponding rules, the-D option is still used.-D INPUT means deleting the rules in the INPUT chain. The remaining options are the same as when we added the rules.-s means taking the corresponding source address as the matching condition, and-j ACCEPT means the corresponding action is accepted. Therefore, the above command means deleting the rules with the source address of 192.168. 1.146 and the action is ACCEPT in the INPUT chain.

The specific structure diagram is as follows:
