:!: ACHTUNG: Server stürzt ab, wenn kein UUID tag angegeben wird.

Setup in iTerm: (cd /Users/Thomas/LIFX/demo):

  • Links: mqtt/LIFX bridge (./mqtt)
  • Mitte: mqtt_publisher (send json)
  • Rechts: mqtt_subscriber (mosquitto_sub -d -h localhost -p 1883 -t „#“)
  • Unten: /usr/local/sbin/mosquitto -c ./mqtt.conf

Terminal:

Virtenv starten:

source python-virtenv/bin/activate

NETCONF/MQTT bridge:

python -i netconf_Server.py   # Achtung: MQTT Broker muss vorher gestartet sein!

ncclient:

from ncclient import manager
from ncclient import xml_
for capability in m.server_capabilities:
...             print(capability)
m = manager.connect_ssh('ios-xe-mgmt.cisco.com', port=10000, username="root", password='C!sc0123',allow_agent=False,hostkey_verify=False,look_for_keys=False)
