Thanks Magnus, and that works
BUT, it does not make sense to me.
errrrr, Mac, why don't you work like others?

If it uses native lookups we can assume that getaddrinfo is broken when it is called from the detached node.
This narrows down the search for the cause of this issue to a more general problem with getaddrinfo on os-x,
leading us to this thread:
You could try just adding nohup to the command that you're executing using ssh. Although i have a hard
time seeing how this would work. An erlang node started with -detached should ignore HUP signals (afaik).

I don't see any difference from outputs from the following commands.
It both uses native lookup.
Anyway, it is not a big deal since I do not use Mac for staging nor production. it's only for development.
However, I hope it's better to be consistent on all kind of *nix environment.
Or, it could be me only.
Any Mac user who what to test this?
