關於DHCP Server幾個疑問 - Linux

debian(jessie)下
我的做法是這樣

# apt-get install isc-dhcp-server //安裝
# vi /etc/network/interfaces
/*
auto eth0
iface eth0 inet static
address 192.168.x.y //x = 0~255 , y = 0 ~253
netmask 255.255.255.0

auto eth0:0
iface eth0:0 inet static
address 192.168.x.254 //要和上面的x相同
netmask 255.255.255.0
*/
# /etc/init.d/networking restart //重啟網路
# vi /etc/default/isc-dhcp-server //變更 INTERFACES="" -> INTERFACES="eth0"
# vi /etc/dhcp/dhcpd.conf
/*
subnet 192.168.x.0 netmask 255.255.255.0 { //要和上面的x相同
range 192.168.x.a 192.168.x.b; //要和上面的x相同 ，a&b 為要給的範圍 0~253
option domain-name-servers 168.95.192.1, 168.95.1.1; //dns 這邊用中華的
option domain-name "********.org"; //改要用的
option routers 192.168.x.254; //要和上面的x相同
option broadcast-address 192.168.x.255; //要和上面的x相同
default-lease-time 60000; //看需要調
max-lease-time 720000; //看需要調
}
*/
# systemctl restart isc-dhcp-server.service //重啟服務
如果有重覆的設定記得註解
