anubi.mdns

This module is a pure python implementation of a mDNS responder. It provides DNS functionalities into a small network that uses the mDNS protocol.

The version number follow the following pattern: MAJOR.MINOR.PATCH.TAG.

• MAJOR version increment on backword incompatible changes
• MINOR version increment on addition of new features
• PATCH version incement on bug fixing and minor changes
• TAG indicates project state (currently alpha)

Status

The project is currently in its alpha state. It used only by me in a small home environement. Right now the mDNS responder listen only on IPv4 mDNS addrress and support only type A resource records.

How to use anubi.mdns

Here 's an example of starting a mDNS responder that resolve some host names.

import signal
import anubi.mdns as mdns

# Create the responder instance
responder = mdns.mDNS()

# Create a SIGINT handler
def sigint_handler(sig_num, stack):
    #just to be sure
    if sig_num == signal.SIGINT:
        #stop the responder on SIGINT signal
        responder.stop()
        print('mDSN responder stopped')

# Register the signal handler
signal.signal(signal.SIGINT, sigint_handler)
# Create records for DNS
responder.add_record(DnsRRecordA('test.local.', 120, '127.0.0.1'))
# Start the responder
responder.start()
# Instruct the user how to stop the application
print('mDSN responder started.\nPress CTRL + C to stop it.')
#  Wait untill the responder terminates
responder.join()
