Dabei sollten gerade Manager und Führungspersonen in Politik und Wirtschaft darauf achten ausreichend Schlaf zu bekommen wie eine aktuelle Studie von Wissenschaftlern der Universität Zürich ergeben hat.

Raspberry Pi – installing configuring running Mosquitto Server (MQTT)

Samstag, September 9th, 2017

Installation of MQTT V3.1

# apt-get update
# apt-get upgrade -y
# apt-get autoremove
# apt-get install mosquitto
# wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
# apt-key add mosquitto-repo.gpg.key
# rm mosquitto-repo.gpg.key
# cd /etc/apt/sources.list.d
# wget http://repo.mosquitto.org/debian/mosquitto-stretch.list
# apt-get update
# apt-get install mosquitto
# apt-get install mosquitto-clients
# service mosquitto Status
# netstat -tln | grep 1883

# mosquitto_sub –d –t Topic
# mosquitto_pub –d –t Topic –m “Hello world!”
# mosquitto_sub -h 192.168.1.10 -t Topic
# mosquitto_pub -h 192.168.1.10 -t Topic -m „Hello world!“

Now that the MQTT broker is installed so we can add some basic security features

# cd /etc/mosquitto/conf.d
# vi mosquitto.conf
    allow_anonymous false
    password_file /etc/mosquitto/conf.d/passwd
    require_certificate false
# mosquitto_passwd -c /etc/mosquitto/conf.d/passwd <first user>
# mosquitto_passwd -b /etc/mosquitto/conf.d/passwd <second user> <password>

Secure IoT healthcare solution – to securely transmit data from a heart-monitoring device to an on-premises healthcare system

Samstag, September 9th, 2017

MQTT (MQ Telemetry Transport) – it is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things (IoT)” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium
