Possible to use localhost/127.0.0.1 as KnownPeers in lsl_api.cfg? #86

Closed balpeaux closed 3 years ago

balpeaux commented 3 years ago

Hello,

I'm trying to use the settings on lsl_api.cfg, however, I'm not sure that they are actually read. Is there a way to check if the settings are being loaded?

Finally, I want to be able to run lsl without any real network interfaces up. Is it possible to use only the local host 127.0.0.1 to send and receive packages?

Thank you in advance

I mostly add an invalid setting in the lsl_api.cfg and check for the error message.

Yes, but with a big disclaimer. KnownPeers sends unicast requests to all configured ports, so this isn't ideal. You can, however, add a multicast route to the loopback interface to make it work (see also #92).
