Ubuntu 18.04.1 настройка ping по имени по сети

Проблема не пингуется сервер ud1804 по имени с винды.
Фича Ubuntu18.04 в том, что при обращении по имени к серверу, например ud1804,  для ping, ssh, (имя сервера 1С)  добавляем к имени .local, т.е. ud1804.local . 
Samba share works with IP but not with hostname from Windows 7
Что делает «.local»?

$ grep 'wins' /etc/nsswitch.conf
user@u1804:~$ ps aux | grep 'winbind\|nmbd\|avahi' | grep -v 'grep'

Увидел u1804.local , так пингуется.
Ниже полезные команды:

$ grep -c 'u1804' /etc/hosts
1
$ sudo nano /etc/hosts
127.0.0.1       localhost.localdomain   localhost
::1             localhost6.localdomain6 localhost6
192.168.0.53    u1804
