TR-069 simulator

A CPE simulator for TR-069 protocol. It supports both TR-098 and TR-181 datamodel formats.

Warning

This project is under active development.

All required TR-069 operations are implemented. Current work focuses on optimizations and compatibility.

Installation

Give it a serial number, point to a datamodel file and the ACS and it should work out of the box.

See server/config.go for available configuration options.

Docker Compose

Add a service to the docker-compose.yml file:

services:
  tr069sim:
    image: ghcr.io/localhots/simulatr69:latest
    volumes:
      - /path/to/datamodel.csv:/app/datamodel.csv
      - sim_state:/state
    ports:
      - 7547
    environment:
      SERIAL_NUMBER: G3000E-9799109101
      DATAMODEL_PATH: /app/datamodel.csv
      STATE_PATH: /state/state.json
      ACS_URL: http://myisp/acs
      LOG_LEVEL: debug

volumes:
  sim_state:

Use

All required methods are supported and should behave realistically, except Upload currently don't do anything. There are quirks though.

Parameter Normalization

NORMALIZE_PARAMETERS when set to true will make the simulator attempt to normalize datamodel parameters. Normalization will bring parameter types to common xsd: prefixed format with values checked against their types: negative unsigned integer numbers will be corrected to zeroes, boolean "yes" will be normalized to "true".

Default is false.

Connection Requests

All connection requests are accepted and trusted. This is done for convenience. If the ACS will set the following parameter values they will be ignored:

• ManagementServer.ConnectionRequestUsername
• ManagementServer.ConnectionRequestPassword

Firmware Upgrades

The simulator supports firmware upgrades in a simple JSON format:

{"version": "123.45"}

If the provided URL can't be loaded or if the firmware file has a different format the simulator will respond with a fault.

If everything is fine the simulator will change DeviceInfo.SoftwareVersion parameter value in its state and pretend to take time to upgrade and reboot.
