howto test emit receiver locally?

[NeroBurner]

Is there a way to emit receive on localhost?

I tried the following

./vban_receptor -i localhost -p 23232 -s test -l 4
./vban_emitter -i localhost -p 23232 -s test -l 4 -b pulseaudio

but got the following error for the emitter

./vban_emitter version 2.1.0

Info: socket_open: opening socket with port 23232

I get the same error for the emitter if I use another random port like 23230

Emitter and receptor only accept ip v4 addresses. So, it works with 127.0.0.1 instead of localhost.
