Avahi локальная коллизия имени

Я определил подсеть на своем сервере, с помощью IP псевдонимов для единственной платы Ethernet. Сегодня, после перезагрузки, avahi демон не разрешает имена хостов больше.

Хосты определили в/etc/avahi/hosts:

172.17.0.10 loki.local
172.17.0.11 thor.local
172.17.0.12 odin.local
172.17.0.13 brunhild.local
172.17.0.14 heimdall.local
172.17.0.15 baldr.local
172.17.0.16 freyja.local
172.17.0.17 tyr.local

и daemon.log после avahi перезапущен:

Так, похоже, что avahi запускается хорошо и затем удаляет хосты впоследствии. Это также загружает много интерфейсов, в которых я не нуждаюсь (IPv6 и мостовая схема докера), но я не знаю, является ли это частью проблемы, и как отключить их.

Это было в порядке перед последней перезагрузкой (было только 2 хоста, loki и Тор), и единственное существенное изменение - то, что я установил vsftpd на хост-машине.
