Тестирование и диагностика Samba и ActiveDirectory
Проверка устойчивости имени хоста (Check hostname persistance)
Устойчивость имени хоста - это ...

local static_host=
local transient_host=
transient_host="$(hostname)" || retval=1
static_host="$(hostnamectl --static)" || retval=1
_command hostnamectl || retval=1

}
Если значение:
- 0, то ...
- 1, то ...
Проверка имени хоста в FQDN [не короткое] (Test hostname is FQDN [not short])
FQDN (от англ. Fully Qualified Domain Name — «полностью определённое имя домена», иногда сокращается до «полное имя домена») — имя домена, не имеющее неоднозначностей в определении.

Если значение:
