Linux的前身是BackTrack Linux发行版。Kali Linux是一个基于Debian的Linux 发行版，包括很多安全和取证方面的相关工具。它由Offensive Security Ltd维护和 资助，最先由Offensive Security的MatiAharoni和Devon Kearns通过重写Back Track来完成。Back Track是基于Ubuntu的一个Linux发行版。 Kali 以SD卡为内存硬盘。为了方便携带，在树莓派上安装Kali Linux是一个不错的选 择。本小节将介绍在树莓派上安装Kali Linux操作系统。 （1）从http://www.offensive-security.com/kali-linux-vmware-arm-image-download/ 网站下载树莓派的映像文件，其文件名为kali-linux-1.0.6a-rpi.img.xz。 （2）下 http://mirrors.neusoft.edu.cn/kali/ kali main non-free contrib deb http://mirrors.neusoft.edu.cn/kali-security kali/updates main contrib non-free 添加完以上几个源后，将保存sources.list文件并退出。在该文件中，添加的软件源 是根据不同的软件库分类的。其中
