Isn't this just behaviour of RPCbind which selects some random sockets
by default? the -h is used to bind it to a specific IP address, not to
bind it to specific ports (as far as i can recall), so what you are
printing is really what I would expect it to be.
Matteo, you worked on this recently, can you shed a light on this? and
if my reasoning above is correct, can you please close the ticket since
it's desired behaviour?
Thanks
