This typically implies the sender may not be listening on the correct IP
address, I would suggest replacing "eth1" with the IP address you wish to
I have embarked on a new campaign to improve the feedback the API provides
when setting up connectivity as this continues to be an ongoing common
problem and entirely non-obvious on new platforms like OS X El Capitan.
Today there are multiple levels of logging but the interesting pieces
require compile time configuration.
Enable trace logging to see which interfaces are in use with the
environment variable PGM_MIN_LOG_LEVEL=TRACE
Trace: Binding receive socket to INADDR_ANY
Trace: Join multicast group 184.108.40.206 on interface index 4
Trace: Multicast send interface set to 10.208.0.98 index 4
