基于嵌入式Linux的裁减方法设计与实现

Design and Implementation of Cut Down Method Based on Embedded Linux System

本文首先分析Linux2．6．6内核新特性的基础，探讨对Linux进行实时化和嵌入式化，即通过配置内核，裁减shell和嵌入式C库对系统定制．使整个系统能够存放到容量较小的FLASH中。然后简单介绍了防火墙的概念，深入地分析了Linux 2．6、6版新型内核防火墙netfilter框架的工作机制及其实现的方式。

This paper first Linux2.6.6 kernel characteristics of the new foundation, Discussion of Linux for real-time and embedded, that is configured kernel, reduction Embedded C shell and the customization of the system, so that the whole system can be kept to the smaller capacity Flash China. It then introduces the concept of firewall, in-depth analysis of the new version of the kernel Linux2.6.6 firewall netfilter framework for the mechanism and the way to achieve.
