isc-dhcp-server -y
                      
                    

配置DHCP Server

                                            
$ 
sudo
vim 
/etc/dhcp/dhcpd
.conf
                      
                    

新增下面內容：

                                            
default-lease-time 600;
max-lease-time 7200;
option domain-name "mydomain.example";
subnet 192.168.1.0 netmask 255.255.255.0 { 
  
range 192.168.1.10 192.168.1.100;
  
range 192.168.1.150 192.168.1.200;
  
option subnet-mask 255.255.255.0;
  
option broadcast-address 192.168.1.255;
  
option routers 192.168.1.1;
  
option domain-name-servers 192.168.1.1, 192.168.1.2;
}

修改/etc/default/isc-dhcp-server

                                            
$ 
sudo
vim 
/etc/default/isc-dhcp-server

找到INTERFACES=""這行並修改，指定DHCP Server所使用的網路卡：

INTERFACES="eth2"

修改/etc/network/interfaces

                                            
$ 
sudo
vim 
/etc/network/interfaces

配置eth2網路卡，新增下面內容：

                                            
auto eth2
iface eth2 inet static
    
address 192.168.1.1
    
netmask 255.255.255.0

讓eth2網路卡設定生效

                                            
# Ubuntu 14.04
$ 
sudo
ifdown eth2; 
sudo
ifup eth2

DHCP Server 啟動|停止|狀態

                                            
$ 
sudo
service isc-dhcp-server start|stop|status

開機不要啟動DHCP Server

                                            
# Ubuntu 16.04
$
