摘要： GRUB是多系统引导管理器，简单的说既能引导Linux，同时也能引导Windows；从LinuxSir.Org 讨论区近四年的观察来看，大多初学者并不能在短时间内掌握GRUB的用法，为了解决初学者在最短时间内掌握GRUB，重写GRUB入门文档还是有必要的；
本文重点介绍了GRUB的men]]>https://blog.youkuaiyun.com/ff110698662/article/details/5969657https://blog.youkuaiyun.com/ff110698662/article/details/5969657ff110698662Wed, 27 Oct 2010 16:47:00 +0800结合"hello world"探讨gcc编译程序的过程
 
1. gcc简介
 
gcc/g++是GNU工程的C和C++编译器。都要用四个步骤中的一个或多个处理输入文件。
·         预处理(preprocessing)
·         编译(compilation)
·         汇编(assembly)
·         连接(linking)

1、概述
 
  L7-filter (Application Layer Packet Classifier for Linux), 是 Linux netfilter 的一个外挂模块, 它能使 Linux 的 iptables 支持 Layer 7 (OSI应用层) 过滤功能, 限制封杀 P2P、即时通讯(MSN、QQ、AIM)软件。

第一步： 更改smb.conf
我们来实现一个最简单的功能，让所有用户可以读写一个Samba 服务器共享的一个文件夹；我们要改动一下smb.conf ；首先您要备份一下smb.conf文件；
