===> SECURITY REPORT:
    This port has installed the following files which may act as network
    servers and may therefore pose a remote security risk to the system.
/usr/local/bin/mosquitto_passwd
/usr/local/sbin/mosquitto
/usr/local/lib/libmosquitto.so.1.4.10

    This port has installed the following startup scripts which may cause
    these network services to be started at boot time.
/usr/local/etc/rc.d/mosquitto

    If there are vulnerabilities in these programs there may be a security
    risk to the system. FreeBSD makes no guarantee about the security of
    ports included in the Ports Collection. Please type 'make deinstall'
    to deinstall the port if this is a concern.

Конфигурационный файл находиться /usr/local/etc/mosquitto/mosquitto.conf

С помощью утилиты mosquitto_passwd создаю файл паролей passwd с логином и паролем для подключения к серверу.

# mosquitto_passwd -c /usr/local/etc/mosquitto/passwd esp8266
Password:
Reenter password:

Запускаю mosquitto.

# /usr/local/etc/rc.d/mosquitto onestart

Проверяю

ps -ax | grep mosquitto
10552 ??  Ss       3:47,77 /usr/local/sbin/mosquitto -c /usr/local/etc/mosquitto/mosquitto.conf -d

sockstat | grep 1883
nobody   mosquitto  10552 3  tcp4   10.215.130.1:1883     *:*
nobody   mosquitto  10552 4  tcp4   10.215.130.1:1883     10.215.130.186:3387

Для запуска mosquitto при старте системы в rc.config добавил строку

mosquitto_enable="YES"

Для добавления в топики информации с датчиков температуры написал скрипт

#!/bin/sh
while true
do
term0=`/usr/local/bin/digitemp_DS9097 -t 0 -q -c /usr/local/etc/digitemp.conf`
term1=`/usr/local/bin/digitemp_DS9097 -t 1 -q -c /usr/local/etc/digitemp.conf`
term2=`/usr/local/bin/snmpwalk -v1 -c ччччч_ro ХХХ.ХХХ.ХХХ.ХХХ .1.3.6.1.4.1.2021.2000.6.4.1.2.5.116.101.109.112.48.1 | awk -F'["]' '{ print $2 }'`

/usr/local/bin/mosquitto_pub -h localhost -t sensors/ds18b20_0 -u temp -P pft,bcm -m $term0
/usr/local/bin/mosquitto_pub -h localhost -t sensors/ds18b20_1 -u temp -P pft,bcm -m $term1
/usr/local/bin/mosquitto_pub -h localhost -t sensors/ds18b20_2 -u temp -P pft,bcm -m $term2
  sleep 6
done

Конструкция -F'[«]' изменяет разделитель awk с пробела по умолчанию на двойные кавычки.

Чтобы скрипт стартовал как демон написал с папке /usr/local/etc/rc.d ещё одни скрипт

#!/bin/sh

# PROVIDE: mqtt
# REQUIRE: DAEMON
# BEFORE: LOGIN
# KEYWORD: shutdown

#
# Add the following lines to /etc/rc.conf to enable mqtt:
#
# mqtt_enable="YES"
#
#

. /etc/rc.subr

name=mqtt
rcvar=${name}_enable
pidfile="/var/run/${name}.pid"

command=/scripts/mqqt-temp
start_cmd="${name}_start"
stop_cmd="${name}_stop"
status_cmd="${name}_status"

mqtt_start() {
  /usr/sbin/daemon -P ${pidfile} -r -f  $command
}

mqtt_stop() {
  if [ -e "${pidfile}" ]; then
    kill -s TERM `cat ${pidfile}`
  else
    echo "${name} is not running"
  fi
}

mqtt_status() {
  if [ -e "${pidfile}" ]; then
    echo "${name} is running as pid `cat ${pidfile}`"
  else
    echo "${name} is not running"
  fi
}

load_rc_config ${name}
run_rc_command "$1"

rc скрипт не демонизирует процесс, для демонизации используется строка /usr/sbin/daemon
