tl;dr

If you are trying to detect if core is running, either run up Sooloos config (PC only) or sniff the LAN for UDP multicast messages on several ports - iirc they are all around 90xx and very obvious when they are being broadcast - iirc one was core beacon, can’t remember what the others were for (possibly store and audio endpoint). It’s long time ago so cannot be sure on exact port numbers - memory very sketchy on the old Sooloos protocols.

You should see the multicast transmissions several times a second, and one of your originators should be your core (and iirc store should be same), but by nature of multicast, which applies to Sooloos config which is looking for same messages.

The UDP multicast messages may be significantly filtered or even dropped altogether. If you don't see evidence of the multicast messages within a few tens of seconds, then assume core is not running or your network is dropping all of them - but as iirc you once had this up and running on a different core device, you must have had a network that at the very least passed these occasionally.

Without the presence of a full set of the UDP multicast messages, Sooloos will not work.
