that's because the first parameter of pahopub is the topic to
publish on, and it's mandatory as it stands, so it's taking "--host"
as the topic name. I'll look into fixing that parsing. If you use:
./a.out /test/abcd <publish_topic> --host iot.eclipse.org
it should work, it does for me.

I am trying to connect to an online broker

compile (gcc pahopub.c -lpaho-mqtt3c) and then run it (./a.out

connect, with a return code of 1 (0x01
Connection Refused, unacceptable protocol version). I have
tried the same with other online brokers as well.
is to be done when “the server does not support the level of
the mqtt protocol requested by the client”?
