ISC DHCP服务器和客户端简单测试

步骤一：源码下载和安装

执行./configure & make; make install

mkdir -p /usr/local/var/db

touch /usr/local/var/db/dhcpd.leases

mkdir -p /usr/local/var/run

touch /usr/local/var/run/dhcpd.pid

步骤二：dhcpd.conf简单配置

default-lease-time 600;

max-lease-time 7200;

subnet 172.16.128.0 netmask 255.255.255.0 {

range 172.16.128.110 172.16.128.120;

}

配置的子网需要和服务器上网口监听的地址同网段。

步骤三：给ens33添加监听地址

ip addr add 172.16.128.10/24 dev ens33

步骤四：启动dhcpd和dhclient

dhclient -d ens37请求分配地址

得到地址如下：

DHCPDISCOVER on ens37 to 255.255.255.255 port 67 interval 5

DHCPOFFER of 172.16.128.110 from 192.168.100.21

DHCPREQUEST for 172.16.128.110 on ens37 to 255.255.255.255 port 67

DHCPACK of 172.16.128.110 from 192.168.100.21
