No system has yet been discovered - no UDP packets #886

Open Sroose opened 4 months ago

Sroose commented 4 months ago

I'm trying out this software on Ubuntu (without docker). My sonos (S2) is on the same network as the ubuntu (both ethernet). I get the error "No system has yet been discovered".

When I perform a tcpdump, I can see absolutely 0 UDP packets related to sonos. My ufw rules are open for the local network. I can in fact see other UDP packets from network devices in the dump.

I've already tried the "disableIpDiscovery" setting, as well as setting the IP in the config.

I would expect to see at least outgooing UDP broadcasts from this tool. What more can be tried?

Is this a barebone ubuntu install? No VM or similar?

You should definitely see outgoing udp destined for port 1900 if it is scanning for systems.

I don't really have any ideas if that isn't the case. I haven't tested this with later node versions on Linux in a while, but I wouldn't expect any changes to the socket code that would cause this.

Maybe there is some SELinux stuff that blocks untrusted applications to do anything with sockets?

yes this is a plain ubuntu 22.04 install. No SELinux installed. The only 'special' config is that I also have a tunnel and docker network interfaces. But, I've set the IP to the eth interface. Also, when I do a tcpdump over all interfaces, none of them pick up outgoing UDP requests.
