Dear players, how do you do?
In the example above, the-R option means modifying the specified chain, Using-R INPUT 1 means modifying rule 1 of the INPUT chain, Using-j REJECT means that the action of changing the first rule in the INPUT chain to REJECT. Note: In the above example, the-s option and the corresponding source address cannot be omitted. Even if we have already specified the number corresponding to the rule, when modifying a rule with the-R option, we must specify the original matching condition corresponding to the rule (if there are multiple matching conditions, we need to specify them).

B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).
