该模拟的UNIX文件系统应该有以下功能： 多级目录的结构，第一目录为用户名，其余的为它的子目录； 多用户的功能，有8个用户使用同一块数据区； 具有用户登录和注册的功能，如果用户没有用户名和密码就应该注册，如果有了用户名和密码就应该登陆； -simulation of the UNIX file system should have the following features : multi-level directory structure, the first directory to the user name, the rest are in a subdirectory; Multi-user functions, eight users with a data area; With user login and registration functions, if users do not have a user name and secret the codes would be registered, if we have a user name and password should landing;

当前不少单位在进行系统改造升级时，面临着如何将各个独立部门开发的应用所采用的数据库统一，以便适应数据大集中的需求，方便将来进行数据挖掘等更高层次的应用。在数据库统一的过程中，如何快速、高效的将已有的基于异种数据库的程序，特别是采用C/C 开发的运行于linux/unix下的程序转换到现有数据库下，成为不少单位面临的问题。当然了，基于RAD开发的程序，基本上不需要进行修改，就能达到目的。 -Many units in the current system upgrades are faced with how to integrate all the independent sector to develop applications using a unified database in order to meet the data needs of large centralized to facilitate future data mining and other higher level applications. The process of reunification in the database, how to quickly and efficiently will have been based on heterogeneous database procedures, in particular the use of C/C development running on linux/unix procedures under the switch to an existing database, became quite a number of units the problems faced. Of course, RAD-based development process, basically do not need to be modified, we can achieve the objectives.

bsd-airtools是一个包，为无线802.11b审计提供了一个完整的工具集。也就是它目前包含了一个基于BSD的WEP程序，被称为dweputils (以及为NetBSD, OpenBSD, 和FreeBSD提供的内核补丁)。它也包含了一个基于curses的类似于netstumbler (dstumbler)的AP检测程序，可以用于检测无线访问点和连接的节点，查看到噪音图像的信号，通过被扫描的APs的交互式的滚动，以及查看每一个的统计信息。-bsd- airtools is a package for wireless 802.11b audit provides a complete set of tools. It is currently contains a BSD-based WEP procedure, called dweputils (as well as NetBSD, OpenBSD, and the FreeBSD kernel patch). It also contains a curses based on the similar netstumbler (dstumbler) AP detection procedures can be used to detect wireless access points and connecting nodes to see images of the noise signal, the APs were scanning the interactive rolling, and a check every statistical information.
