This document describe the fundamental concept of network simulator-2, a simulation environment for computer networking field of engineering. It covers the description of basic tools and components used in network simulations.

本次实验的目的在于将nachos中的锁机制和条件变量的实现补充完整，并利用这些同步机制实现几个基础工具类。实验内容分三部分：实现锁机制和条件变量，并利用这些同步机制将实验一中所实现双向有序链表类修改成线程安全的；实现一个线程安全的表结构；实现一个大小受限的缓冲区（详细内容请看nachos-labs.pdf）。-the purpose of the experiment is to the nachos lock mechanism and conditions for the realization of supplementary variables integrity, Using these synchronization mechanism based tool for achieving several categories. Experiment three parts : achieving lock mechanism and variable conditions, Using these experimental synchronization mechanism as a bidirectional orderly objectlist revise the security thread; the realization of a security thread table structure; the realization of a limited size of the buffer zone (for details, please see nachos- labs.pdf).

在Linux系统的/etc目录下有这样一个文件passwd，该文件里包含系统中所有用户信息的记录，记录里包含每个用户的如下信息：用户名、密码、用户ID、组ID、用户全名、用户主目录和用户登录所用的shell。请设计一个脚本（shell）程序能实现增加、删除、查找和显示特定用户信息的功能。你们可以通过创建一些UNIX/LINUX shell 脚本文件来满足以上需求。-In the Linux system,/etc directory there is such a file passwd, this file contains all the user information system, records, record where each user that contains the following information: user name, password, user ID, group ID, user" s full name , the user" s home directory and the user logged in with the shell. Please design a script (shell) program enables to add, delete, search and display information on a specific user function. You can by creating a number of UNIX/LINUX shell script file to meet the above requirements.
