Тестирование и диагностика Samba и ActiveDirectory

Проверка постоянства имени хоста (Check hostname persistance)

Постоянство имени хоста - это сохранение имени компьютера после перезагрузки. 

check_hostnamectl() {
   local retval=0
   local static_host=
   local transient_host=
   transient_host="$(hostname)" || retval=1
   static_host="$(hostnamectl --static)" || retval=1
   _command hostnamectl || retval=1
   test "$static_host" = "$transient_host" || retval=1
   return $retval
}

Если значение:

  • 0, то постоянство не настроено
  • 1, то постоянство работает корректно

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. 

test_hostname()
{
    local host="$HOSTNAME_COMMON"
    echo $host
    echo
    test "$host" != "${host/.}" || return 2
}

Если значение:

  • 0, то ...
  • 2, то ...

Использование связки ключей в качестве кеша учетных данных Kerberos (Using keyring as kerberos credential cache)

 local ccache=
   ccache=$(/usr/sbin/control krb5-conf-ccache)
   _command /usr/sbin/control krb5-conf-ccache
   _command test -n "$ccache" -a "$ccache" == "keyring" || return 2

Проверка состояния поиска DNS kerberos KDC (Check DNS lookup kerberos KDC status)

local retval=0
   echo -n "/etc/krb5.conf: dns_lookup_kdc "
   if grep -q '^\s*dns_lookup_kdc\s*=\s*\([Tt][Rr][Uu][Ee]\|1\|[Yy][Ee][Ss]\)\s*$' /etc/krb5.conf; then
       echo "is enabled"
   else

           echo "is enabled by default"
           retval=2
       fi
   fi
   echo
   return $retval

Проверка существования кэша учетных данных компьютера (Check machine crendetial cache is exists) +

ls -l /etc/krb5.keytab

Если файл будет найден, кэш доменных учетных данных существует, если нет, то используются локальные учетные записи.

Проверка списка учетных данных компьютера в keytab-файле (Check machine credentials list in keytab)

klist -ke

    echo "HOSTNAME_SHORT = '$HOSTNAME_SHORT'"
    echo
    test "$netbios" = "$host" || return 1

Чтобы проверить, что у Вас установлены все общие пакеты, выполните следующие команды: 

# rpm -q alterator-auth
# rpm -q libnss-role
# rpm -q libkrb5
# rpm -q libsmbclient

Все вышеуказанные пакеты должны быть установлены.

Проверка пакетов групповых политик (Check group policy packages) +

 # rpm -q local-policy
 # rpm -q gpupdate

Если обе команды сработают, то у Вас установлены пакеты для групповых политик.

Проверка пакетов SSSD AD (Check SSSD AD packages) +

# rpm -q task-auth-ad-sssd

Если команда сработает, то у Вас используется Samba с AD-SSSD.

Проверка пакетов SSD Winbind (Check SSSD Winbind packages) +

# rpm -q task-auth-ad-winbind

Если команда сработает, то у Вас используется Samba с WinBind.
