Добрый день уважаемые коллеги. Проблема на ВМ, слейв ноде кластера. На него не доходят ntp запросы c IP телефонов, но как выяснилось и ping Не знаю важно ли это, но, переносил машину на новый хост, интерфейсы переименовались с enp2s0 на eth0 и enp4s0 на eth1 при переносе. Я переименовал обратно с помощью ip ... Firewall отключен. Iptables прозрачный По ssh подключаюсь к этой машине
