I see that on my currently working master, when I 'ping builder', I
get a log message that says, "2017-04-10 11:55:10-0700 [Broker,client]
SlaveBuilder.remote_print(linux-64-bit-bat): message from master:
ping"

And also I get messages to the effect of, "2017-04-10 11:51:32-0700
[Broker,client] SlaveBuilder.remote_print(poky): message from master:
attached", but on this new server, I do not get those messages.

Certainly feels like some security/port issue... but I'm not sure where to look.

Thanks,
