1. Linux Power Management Global architectureLinux power management is very complex, involving system-level standby, frequency-voltage transformation, System idle processing, and each device driver support for system standby and runtime power management for each device, which can be say and every device driver in the s

I. Preparatory work1.I. LFS TARGET architectureLFS's primary target architecture is Intel's 32-bit architecture. The 32-bit computer architecture is the most widely supported Linux system, while the 32 architecture enables open source and non-open source software to work harmoniously.In order to build the system, the prerequisite is that, in addition to the

on. These tasks are initialized to a specific session and can therefore be referred to as session Init. There are two modes for users to use Linux: Character mode and graphical interface. In character mode, session initialization is relatively straightforward. Only one shell can be started after the user logs on, using the system through the shell command. Various shell programs support a startup script th

(command # Make Dep bzimage ).4.3.2 daemon process reduction The squid daemon is used as an example. In addition to the configuration file (squid. in conf), you can further remove some of the cache supported by the program. In version 2.4.stable1, three cache storage formats are provided: UFS, aufs, and null. The last one indicates that the cache is not used, so it meets the requirements. Then, use the configuration program to set (command #./configu

relationship between kernel functions and system calls. We do not think of the kernel function is too complex, in fact, they are similar to ordinary functions, but only in the kernel implementation, so to meet some kernel programming requirements. System call is a layer of user access to the kernel of the interface, which itself is not a kernel function, after e

Kernel, is the core of an operating system. It is responsible for managing the system's process, memory, device driver, file and network system, which determines the performance and stability of the system. Linux as a free software, with the support of a wide range of enthusiasts, the kernel version is constantly updat

If you want to use a CD, USB flash drives should generally install them to a specific location in the directory. Proc: This directory is a virtual directory of memory shadow, which contains a lot of system field data, suchProgramNumber, interrupt status, CPU information, etc. The information

controlled by intruders. Because of the openness of the code, we can get a lot of the original code of the Linux application, and modify it according to our needs. Therefore, bugs can be easily found and quickly fixed. However, when a vulnerability is revealed, the system administrator is negligent in patching the vulnerability, which can easily cause intrusion. What's worse, hackers can obtain the root sh

addition, the annotations in the Firestarter script file are very clear, which makes it easy for you to modify and redefine some parameters. In general, Firestarter firewall is applicable to the security protection of stand-alone workstations, servers, small network servers, and home Linux systems. it is competent for general system security tasks in Linux.
