1、fedora8 配置单个作用域和多个作用域的 DHCP 服务一、单个作用域假设 dhcp 服务器地址在 192.168.0 网段，网关：192.168.0.1，dns：202.100.64.68本人水平有限，请高手指点-#先查看 dhcp 的安装情况，貌似 Fedora8 里没有 dhcp 安装包，请自行下载或 yumrootlocalhost # rpm -qa | grep dhcplibdhcp6client-0.10-51.fc8libdhcp-1.27-3.fc8dhcpv6-client-0.10-51.fc8libdhcp4client-3.0.6-10.fc8dhcp-3.0.
2、6-10.fc8#先查看一下 dhcp 的主配文件，需要咱们自己来写，这样很麻烦，我们可以从主配文件中看到有 sample 的位置，用 sample 吧，很方便。rootlocalhost # cd /etcrootlocalhost etc# more dhcpd.conf-# dhcp Server Configuration file.# see /usr/share/doc/dhcp*/dhcpd.conf.sample#-rootlocalhost etc# cd /usr/share/docrootlocalhost doc# ls *dhcp*dhcp-3.0.6:api+pro
