I'm using a raspberry pi image that has the mosquitto broker installed. To troubleshoot, instruction was to run:
pi@raspberrypi:/ $ mosquitto_sub -v -t "gateway/+/rx"
However that resulted in:
-bash: mosquitto_sub: command not found
Even though mosquitto was running:
pi@raspberrypi:/ $ sudo service mosquitto status ● mosquitto.service - LSB: mosquitto MQTT v3.1 message broker Loaded: loaded (/etc/init.d/mosquitto; generated; vendor preset: enabled) Active: active (running) since Sun 2018-09-30 21:43:51 UTC; 5h 14min ago Docs: man:systemd-sysv-generator(8) Process: 347 ExecStart=/etc/init.d/mosquitto start (code=exited, status=0/SUCCESS) CGroup: /system.slice/mosquitto.service └─432 /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
Searching the problem did not produce easy to find answer.
