使用DVL Linux练习Linux安全攻防

　　Damn Vulnerable Linux (DVL)是一份用于Linux安全攻防的Linux发行版，不是用来作为桌面系统的Linux。它的开发者打造它的目的就是使得改发行版易于受到攻击，它是为系统安装的学生和爱好者所设计的。

　　Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn't. Its developers have spent hours stuffing it with broken, ill-configured, outdated, and exploitable software that makes it vulnerable to attacks. DVL isn't built to run on your desktop -- it's a learning tool for security students.

　　DVL is a live CD available as a 150MB ISO. It's based on the popular mini-Linux distribution Damn Small Linux (DSL), not only for its minimal size, but also for the fact that DSL uses a 2.4 kernel, which makes it easier to offer vulnerable elements that might not work under the 2.6 kernel. It contains older, easily breakable versions of Apache, MySQL, PHP, and FTP and SSH daemons, as well as several tools available to help you compile, debug, and break applications running on these services, including GCC, GDB, NASM, strace, ELF Shell, DDD, LDasm, LIDa, and more.

　　DVL was initiated by Thorsten Schneider of the International Institute for Training, Assessment, and Certification (IITAC) and Secure Software Engineering (S²e) in cooperation with Kryshaam from the French Reverse Engineering Team.
