How to advertise a sub-type

[cmcqueen]

Reading through the code, it looks as though a sub-type (such as _craig._sub._http._tcp.local.) could be advertised as follows:

info = ServiceInfo("_craig._sub._http._tcp.local.",
                   "Craig._http._tcp.local.",
                   address=socket.inet_aton("192.168.1.100"),
                   port=80,
                   properties=desc, server="craig.local.")

It seems to nearly work, but it doesn't necessarily show up when another PC browses the main type (_http._tcp.local. in this case).

Also, how would it be possible to advertise multiple sub-types?

Hi,

Thanks for the message.

To tell you the truth, I don't remember trying to advertise a service... but I think it should work...

I am a bit confused by you message...

Your code is just showing that you create a service, not that you start a task with "service_register", so do you?

When you say " it doesn't necessarily show up when another PC", do you mean it "sometimes does", "it always does" or it "never does".... also it the listening PC using aiozeroconf or something else?

Cheers

I just quoted the one essential line, which I was testing in the context of the registration.py example. The essential point is that the first parameter can be "_craig._sub._http._tcp.local", which advertises that sub-type. But, it doesn't also advertise the type "_http._tcp.local".

When you say " it doesn't necessarily show up when another PC", do you mean it "sometimes does", "it always does" or it "never does".... also it the listening PC using aiozeroconf or something else?

If I do a query in Windows using dns-sd -B _http._tcp, then it doesn't appear. But querying the sub-type using dns-sd -B _craig._http._tcp does find it. With avahi on Linux, using avahi-browse _http._tcp it also doesn't appear. Running avahi-browse _craig._sub._http._tcp, it does. The only thing that does kind-of work is, running the avahi-discover GUI, it shows up in the tree under Web Site.

So, a service should be able to be advertised with one type such as _http._tcp, as well as one or more sub-types.
