1. Установить пакет

apt install isc-dhcp-server |
2. Указать прослушиваемый интерфейс для DHCP сервиса
|
1 |
nano /etc/default/isc-dhcp-server |
значение:
|
1 |
INTERFACES="" |
меняем на:
|
1 |
INTERFACES="enp1s8" |
где enp1s8 интерфейс на котором раздавать dhcp
3. Настроить DHCP, привести к виду файл конфигурации

cat /etc/dhcp/dhcpd.conf | grep -v ^# | grep -v ^$ default-lease-time 600; max-lease-time 7200; log-facility local7; subnet 192.168.10.00 netmask 255.255.255.192 { range 192.168.10.21 192.168.10.62; option domain-name-servers 192.168.1.2, 192.168.1.3; option domain-name "specnix.org"; option subnet-mask 255.255.255.192; option routers 192.168.10.1; option broadcast-address 192.168.10.63; default-lease-time 600; max-lease-time 7200; } |
4. Сделать, то что забыл маинтейнер пакета
|
1 2 |
