        我已经使用了近半年了，唯一的感觉就是真后悔没有早一点发现这个工具。
        其实这是一个Sourceforge的一个开源项目，最近刚刚更新到2.1，支持Windows NT全系列操作系统。下面给出项目链接，有兴趣的可以去看看。

Each language has its purpose, however humble. Each language expresses the Yin and Yang of software. Each language has its place within the Tao, But do not program in COBOL if you can avoid it.

Thus spake the master programmer:
"After three days without programming, life becomes meaningless."

A novice asked the Master: "Here is a programmer that never designs, documents, or tests his programs. Yet all who know him consider him one of the best programmers in the world. Why is this?"
The Master replies: "That programmer has mastered the Tao. He has gone beyond the need for design; he does not become angry when the system crashes, but accepts the universe without concern. He has gone beyond the need for documentation; he no longer cares if anyone else sees his code. He has gone beyond the need for testing; each of his programs are perfect within themselves, serene and elegant, their purpose self-evident. Truly, he has entered the mystery of the Tao."

A manager went to the master programmer and showed him the requirements document for a new application. The manager asked the master: "How long will it take to design this system if I assign five programmers to it?"
"It will take one year," said the master promptly.
"But we need this system immediately or even sooner! How long will it take it I assign ten programmers to it?"
The master programmer frowned. "In that case, it will take two years."
"And what if I assign a hundred programmers to it?"
The master programmer shrugged. "Then the design will never be completed," he said.

"A well-written program is its own heaven; a poorly-written program is its own hell."

A program should be light and agile, its subroutines connected like a strings of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little nor too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity.

A program, no matter how complex, should act as a single unit. The program should be directed by the logic within rather than by outward appearances.

Does a good programmer refuse to maintain his code?

Thus spake the master programmer:
"Without the wind, the grass does not move. Without software, hardware is useless."]]> http://www.gmxpsoft.com/default.asp?id=49 <![CDATA[2009年全国大学生信息安全竞赛]]> Gmxp http://www.gmxpsoft.com/ gmxp@gmxpsoft.com 2009-08-19T16:35:44+08:00 2009-08-19T16:35:44+08:00         To 一个郁闷中的人：如果暂时没有看到回报，可能是努力的还不够，不要灰心，继续加油啊~

Restrictions on Indicating Receive Packets
        A connectionless miniport driver must not indicate a receive packet to a protocol driver while the miniport driver’s packet filter for that protocol driver is set to zero. When a miniport driver’s MiniportInitialize function is called, the miniport driver’s packet filter should be set to zero. When the packet filter is zero, receive indications are disabled. After a miniport driver’s MiniportInitialize function has returned, a protocol driver can set OID_GEN_CURRENT_PACKET_FILTER to a nonzero value, thereby enabling the miniport driver to indicate receive packets to that protocol.
......
         A driver’s Protocol(Co)ReceivePacket or ProtocolReceive function can be called as soon as the protocol sets up a packet filter with OID_GEN_CURRENT_PACKET_FILTER for the binding. For the NULL filter, receive indications are enabled on return from a successful call to NdisOpenAdapter.

        翻译成中文，大概就是在绑定完下层网卡后，必须向它发送一个OID_GEN_CURRENT_PACKET_FILTER的Request来指定要接收的数据包的类型，而不发送Request的话，默认是不接收任何数据包。自己向下层网卡正确发送完Request后，就可以收到你想要的数据包了。
        让人很郁闷的是，对于协议驱动这么重要的步骤，DDK中仅仅在一个“很角落”的地方提到，而我正在看的网络驱动的那本书更是只字不提，把WinPcap的协议驱动翻了个遍也没有特别提及，网络上更加没有相关消息，似乎大家都认为只要绑定网卡成功就能收到数据了。]]> http://www.gmxpsoft.com/default.asp?id=45 <![CDATA[Dr.COM密码查看器]]> Gmxp http://www.gmxpsoft.com/ gmxp@gmxpsoft.com 2009-01-03T21:41:06+08:00 2009-01-03T21:41:06+08:00


        在Dr.COM 3.481 + Windows XP SP3下测试通过，其他的版本估计也差不多。
        不过，代码不能贴，bin不能放，思路不能说，就贴张图留下自己逆向工程学习过程中的一点脚印而已。这么做是有原因的，望大家理解~]]> http://www.gmxpsoft.com/default.asp?id=44 <![CDATA[网站全新更换]]> Gmxp http://www.gmxpsoft.com/ gmxp@gmxpsoft.com 2009-01-02T16:30:47+08:00 2009-01-02T16:30:47+08:00 PJBlog系统，功能挺完善的，主题也很丰富，可惜是用asp开发的。

        考试结束了，按照既定的计划准备，应该没什么问题；
        360game的比赛结束了，不过今天才公布赛果，嗯，PSP是我的了，不过360似乎没有这么容易给我，要我亲自去北京拿- -！过完年再说吧，顺便参观一下360和见识一下某些大牛长什么样，呵呵；
        某些事情顺利通过验收；
        课程设计已经搞定，可以专心学习了；
        悄悄的说一声，我要开始学习RING0的网络方面啦，继续努力。
        新年新开始，预祝大家新的一年里开开心心，学业所成/事业有成/永远年轻~]]> http://www.gmxpsoft.com/default.asp?id=3
