1、I基于基于 LinuxLinux 的的 DHCPDHCP 服务器配置服务器配置摘 要随着互联网的普及，人们的工作、学习和生活与网络联系越来越紧密，搭建了许多不同的网络，如企业网、校园网和城区网等。网络管理是大型计算机网络成功的关键因素，利用 DHCP 服务已经显得相当流行。动态主机分配协议（DHCP）的运用也显得越来越重要。在实际的操作过程中，构建 DHCP 服务器也越来越常见。而采用 DHCP 技术动态地为主机配置参数，可以有效解决目前 IP 地址资源不足和用户的移动性等问题，并能极大地减轻大型网络管理员的工作量，减少手工网络配置的错误，有利于快速地搭建一个大型网络或修改其网络配置。构建 D
2、HCP 服务器需要一个稳定的操作系统和服务器软件。在操作系统的竞争之中，Linux 以“免费、高效率、稳定性、跨平台”的特点，加上功能强大，对硬件配置需求低等优势，迅速地占领了一些其它商业操作系统市场，而且还在持续蔓延和发展。而 Red hat Linux 操作系统经过一段时间的发展已经成为一个主要的 Linux 发行版本，越来越多的企业和个人开始采用它来进行工作,学习和娱乐。同时，Red Hat Linux 中附带的 DHCP 服务也是目前 Internet 上最受欢迎的动态 IP 地址分配服务器。本文以企业网的 DHCP 服务器为基础，一步步地描述了 DHCP服务器的构建过程。关键词：企业

4、 computer networks, a key factor in the success of the use of DHCP service has become very popular. Dynamic Host Allocation Protocol (DHCP) use has become increasingly important. In the actual operation, building a DHCP server is also becoming more common. Technological developments and the use of D
