rndc-python 0.1.1

Python client for ISC BIND's RNDC

rndc-python

Python client library for talking to ISC BIND's RNDC service.

Requirements

• Python 3.10+

Installation

pip install rndc-python

Or using uv:

uv add rndc-python

Command-line Interface

The package includes a CLI tool rndc-python-cli:

# Using CLI options
rndc-python-cli -s 127.0.0.1 -p 953 -a sha256 -k <base64-secret> status

# Using environment variables
export ZPAPI_RNDC_HOST=127.0.0.1
export ZPAPI_RNDC_PORT=953
export ZPAPI_RNDC_ALGORITHM=sha256
export ZPAPI_RNDC_SECRET=<base64-secret>
rndc-python-cli status

# Mix of both (CLI options override env vars)
rndc-python-cli --port 954 reload

Configuration

The client can read its settings from environment variables (or a .env file):

• ZPAPI_RNDC_HOST
• ZPAPI_RNDC_PORT
• ZPAPI_RNDC_ALGORITHM (e.g. hmac-sha256)
• ZPAPI_RNDC_SECRET
• ZPAPI_RNDC_TIMEOUT
• ZPAPI_RNDC_MAX_RETRIES
• ZPAPI_RNDC_RETRY_DELAY

You can also configure the client directly in Python:

from rndc_python import RNDCClient, TSIGAlgorithm

client = RNDCClient(
    host="127.0.0.1",
    port=953,
    algorithm=TSIGAlgorithm.SHA256,
    secret="your-base64-secret-here",
    timeout=10,
    max_retries=3,
    retry_delay=2,
)

All parameters are optional if you have configured environment variables or a .env file.

Usage

Python API

from rndc_python import RNDCClient

with RNDCClient() as rndc_client:
    print(rndc_client.call("status"))
