I currently have a http server implemented in python using flask. The service is registered using the zeroconf module:
info = ServiceInfo('_http._tcp.local.',
'MyServer._http._tcp.local.',
inet_aton(host), port, properties={})
zc = Zeroconf()
zc.register_service(info, allow_name_change=True)
Also, I have a go application browsing the available services using zeroconf. The problem is that if I start the go program after the python server the go program never discovers the server. If I start the go program first there's no issue. I even try extending the ttl on the register_service function with no results.
I'm trying that the go program discovers the python servers that where already running when it gets started.
I recently discover that the go part functions perfectly, I register the service using avahi-publish and go discover it correctly. So I guess the python module is the problem. I know now that I can run avahi but I would like a python implementation of the protocol, having dependencies only in python.
