/usr/ports/net/samba410
make install clean

Если в процессе установки получаю ошибку

===>  llvm80-8.0.1_3 needs Python 3.6 at least, but 2.7 was specified.
*** Error code 1

Stop.
make[8]: stopped in /usr/ports/devel/llvm80
*** Error code 1

В файле /etc/make/conf добавляю строку

PYTHON_VERSION=python3.6

перехожу в /usr/ports/devel/llvm80 и запускаю установку

cd /usr/ports/devel/llvm80
make install clean

Создаю в папке /usr/local/etc/ создаю файл smb4.conf

cat /usr/local/etc/smb4.conf
