Service Configuration - FreeTAKServer

Overview

FreeTAKServer provides multiple network services for TAK clients and applications:

TCP CoT Service: Unencrypted Cursor on Target message service
SSL CoT Service: TLS-encrypted Cursor on Target message service
REST API Service: RESTful HTTP API for programmatic access
HTTP TAK API Service: HTTP endpoint for TAK protocol operations
HTTPS TAK API Service: Secure HTTPS endpoint for TAK protocol operations

Each service can be configured independently through MainConfig settings.

TCP CoT Service

The TCP CoT service handles unencrypted TAK Cursor on Target (CoT) messages over TCP.

Configuration

integer

default:"8087"

TCP port for unencrypted CoT connectionsEnvironment variable: FTS_COT_PORTYAML: Addresses.FTS_COT_PORT

integer

default:"1024"

Buffer size in bytes for receiving CoT data from clientsEnvironment variable: FTS_DATA_RECEPTION_BUFFERYAML: System.FTS_DATA_RECEPTION_BUFFER

integer

default:"4"

Maximum time in seconds to wait for data reception before timeoutEnvironment variable: FTS_MAX_RECEPTION_TIMEYAML: System.FTS_MAX_RECEPTION_TIME

Service Constants

Defined in FreeTAKServer/services/tcp_cot_service/configuration/tcp_cot_service_constants.py:

SERVICE_NAME = 'tcp_cot_service'
XML = 'XML'
DATA_RECEPTION_BUFFER_SIZE = 1024

Message Types

SEND_TO_ALL (0): Broadcast message to all connected clients
SEND_TO_SOME (1): Send message to specific clients

Example Configuration

YAML:

Use the SSL CoT service for production deployments to ensure encrypted communications and client certificate authentication.

REST API Service

The REST API provides programmatic HTTP access to FreeTAKServer functionality.

Configuration

integer

default:"19023"

Port for the REST API serviceEnvironment variable: FTS_API_PORTYAML: Addresses.FTS_API_PORT

Authentication

The REST API uses Bearer token authentication with HTTPTokenAuth. From FreeTAKServer/services/rest_api_service/controllers/authentication.py:

from flask_httpauth import HTTPTokenAuth

auth = HTTPTokenAuth(scheme='Bearer')

Tokens are validated against:

APIUser table for API users
SystemUser table for system users

Successful authentication logs API calls to the database with:

User ID
Timestamp
Request content
Endpoint URL

API Endpoints

The REST API provides blueprints for:

Data Packages: Upload and manage data packages
Emergencies: Create and manage emergency notifications
ExCheck: Checklist management
GeoObjects: Create and manage geographic objects
Missions: Mission planning and coordination
User Management: User administration

Example Configuration

YAML:

Addresses:
  FTS_API_PORT: 19023
  FTS_API_ADDRESS: "0.0.0.0"

System:
  FTS_OPTIMIZE_API: true

Environment Variables:

export FTS_API_PORT=19023
export FTS_API_ADDRESS="0.0.0.0"
export FTS_OPTIMIZE_API=true

API Usage

# Authenticate and get token
curl -X POST http://server-ip:19023/api/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"password"}'

# Use token for authenticated requests
curl -X GET http://server-ip:19023/api/users \
  -H "Authorization: Bearer YOUR_TOKEN_HERE"

Best Practices

Always use encrypted services (SSL CoT, HTTPS TAK API) for production deployments to protect sensitive tactical data.

Configure DataPackageServiceDefaultIP and UserConnectionIP to match the IP address or domain name that clients use to connect.

Use SSL/TLS services for production environments
Keep certificate files secure with appropriate filesystem permissions
Regularly rotate certificates and passwords
Monitor service logs for connection issues
Use different ports for each service to avoid conflicts
Configure firewalls to allow only necessary service ports
Set appropriate buffer sizes based on your network conditions
Use the REST API for automated monitoring and management
