cmxreceiver-python

A basic web service to accept CMX data from a Cisco Meraki network

• Accept a GET request from Meraki and respond with a validator
• Meraki will POST to server, if validated.
• POST will contain a secret, which can be verified by the server.
• JSON data will be in the req.body.data. This will be available in the cmxData function's data object. *note: CMX is now called Scanning API in Meraki documentation

cmxreceiver.py

-- The basic app will only place the data received on the console.

cmxreceiver-mongodb.py

-- Extends the basic app by placing data into a local MongoDB database.

Prerequisites

• Flask must be installed http://flask.pocoo.org/docs/0.12/

• Cisco Meraki Network with CMX/Scanning API enabled and configured to point to this server

• Option 1 - Basic Receiver

python3 cmxreceiver.py -v <validator> -s <secret>'

• Option 2 - Receiver with MongoDB

python3 cmxreceiver-mongodb.py -v <validator> -s <secret>'

flask run -h 0.0.0.0
 * Running on http://0.0.0.0:5000/

• Port: 5000
• CMX Post URL: http://yourserver:5000/
