Задание:
- Основной DNS-сервер реализован на HQ-SRV
- Сервер должен обеспечивать разрешение имён в сетевые адреса устройств и обратно в соответствии с таблицей 3
- В качестве DNS сервера пересылки используйте любой общедоступный DNS сервер(77.88.8.7, 77.88.8.3 или другие)
| Устройство | Запись | Тип |
| HQ-RTR | hq-rtr.au-team.irpo | A |
| BR-RTR | br-rtr.au-team.irpo | A |
| BR-FW | br-fw.au-team.irpo | A |
| HQ-SRV | hq-srv.au-team.irpo | A,PTR |
| HQ-CLI | hq-cli.au-team.irpo | A |
| BR-SRV | br-srv.au-team.irpo | A,PTR |
| ISP (интерфейс направленный в сторону HQ-RTR) | docker.au-team.irpo | A |
| ISP (интерфейс направленный в сторону BR-RTR) | web.au-team.irpo | A |
Вариант реализации 1:
- Устанавливаем пакет dnsmasq
apt-get update apt-get install dnsmasq
mcedit /etc/dnsmasq.conf
Запускаем dnsmasq и добавляем его в автозапуск
systemctl enable --now dnsmasq
HQ-CLI:
- Проверяем работу DNS:
