思科路由器交换机中的access-list(访问列表)最基本的有两种,分别是标准访问列表和扩展---- access-list 1 permit host 192.46.27.8
---- access-list 1 permit host 192.46.27.12
---- 注意,因为所有的访问列表会自动在最后包括该语句.
---- 顺便讨论一下标准型IP访问列表的参数“log”,它起日志的作用.一旦访问列表
作用于某个接口,那么包括关键字“log”的语句将记录那些满足访问列表放在所有其它VLAN上直接.

Any machine connected to the Internet is a potential target for malicious attacks. There is a tool called Fail2Ban that can be used to mitigate illegal access on the server. What is Fail2Ban?

The EXPLAIN command in Oracle is used to analyze the execution plan of a SQL statement. The method of use is to add the EXPLAIN keyword before the SQL statement. EXPLAIN results contain information such as ID, operator type, row count estimate, cost estimate, output row count estimate, access predicates, and filter predicates, which can be used to optimize query performance, identify costly operators, and tables that may benefit from optimization techniques.
