Тестирование и диагностика Samba и ActiveDirectory

Проверка устойчивости имени хоста (Check hostname persistance)

   local retval=0
   local static_host=

   transient_host="$(hostname)" || retval=1

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.
