Related background: Why and whatIn recent years, Linux system has been widely concerned and applied by computer industry because of its excellent performance and stability, the flexibility and expansibility of open Source feature, and the lower cost. But in terms of security, the Linux kernel only provides
In linux, snmptrap sends and receives requests to the managed server every five minutes because you need to manage server parameters, such as CPU usage and IOwait metrics. This type of indicator is a business indicator. It is a required parameter and an alarm indicator is required. However, because the alarm information is generally triggered by the managed server, the managed server cannot actively use snmpwalk
When we manage servers, the ipvsw system is more intuitive, including cpu usage, memory usage, and so on, as long as the task manager in the Remote Desktop is clear at a glance. However, in a linux environment, it is not that easy. In particular, large websites run on servers or vps. If server performance consumption cannot be detected in a timely manner, the website may be accessed during peak hours, I don't know what the problem is. Today we will in

First, copy the required basic network commands to a Linux instance.Copy Ping and ifconfigTo add a network function, you must be driven by the NIC. The NIC Driver is pcnet32.However, pcnet32 has a dependency module that is MII, and MII has no dependency module,So we only need to copy the two modules to ourIn Linux, chec

Recently, I have made up my mind to take a good look at this book, and I plan to write some study notes to record some gains an
