README for openntpd openntpd expects to have a user and group dedicated to it. By default, _ntp. To create them, use the following or similar commands, edited to your needs. # groupadd -g 83 _ntp # useradd -g _ntp -u 83 -c "NTP Daemon" -d /var/empty -s /bin/false _ntp *NOTE* A post-install script has been added to the port which takes care of the above.
