咕噜。Diamond Sweetheart's doll socks, which I just bought recently, like that everything in their house has its own logo. It doesn't feel soft, but this pair of socks is easy to hook and break, but are there any super cute ones?For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~Physically speaking, firewalls can be divided into hardware firewalls and software firewalls.Well, we've reviewed the concept of rules, And it has been understood that, A rule consists roughly of two logical units, Match conditions and actions, It is useless to say so much, Let's define a rule by hand. Here, we still take the INPUT chain in the filter table as an example, because the filter table is responsible for the "filtering" function, and if all messages sent to the local machine need to be filtered, they will first pass through the INPUT chain (PREROUTING chain has no filtering function), which is very similar to the "entry" scenario we refer to. Therefore, using the INPUT chain in the filter table as an example is helpful for us to understand.Use the following command to append a rule to the INPUT chain of the filter table, which means to accept all messages from 192.168. 1.146 destined for the local machine.到那时候可就真的成了人为刀俎我为鱼肉，他田荣也算英勇一世，怎么可能任人鱼肉？所以现在绝对不能离开临淄，至少到现在为止，还掌控着原来齐国的大部分土地，经过两年的恢复，实力壮大不少。
