【转】Ubuntu DHCP server 设置笔记

安裝dhcp-Server

sudo apt-get install dhcp3-server 安裝dhcp server相關套件

設定dhcp Server使用的網路卡

sudo cp /etc/default/dhcp3-server /etc/default/dhcp3-server_backup 複製一預設的dhcp server網卡設定檔 sudo gedit /etc/default/dhcp3-server 修改dhcp server的網卡設定檔 INTERFACES="" => INTERFACES="eth2" 將dhcp server網卡設為eth1

修改dhcp Server設定檔

sudo cp /etc/dhcp3/dhcpd.conf /etc/dhcp3/dhcpd.conf_backup 複製一預設的dhcp server設定檔 sudo gedit /etc/dhcp3/dhcpd.conf 修改dhcp server的網卡 # A slightly different configuration for an internal subnet.

subnet 192.168.1.0 netmask 255.255.255.0 {

range 192.168.1.0 192.168.1.255;

option domain-name-servers 140.112.254.4,140.112.2.2;

option domain-name "ubtw.net";

option routers 192.168.0.1;

option broadcast-address 192.168.1.255;

default-lease-time 600;

max-lease-time 7200;

} 設定dhcp server的對內網卡(eth2)

重新啟用dhcp Server

將對內網卡eth2設一個固定IP: dhcp Server sudo /etc/init.d/dhcp3-server restart 重新啟動dhcp Server
