[erlang-questions] where to find correct documentation for erlang distribution over SSL?

Hi Kris,

I hadn't seen that release note. Excellent. So it is supposed to work. 
Thanks OTP peoples :-)

So, have you tcpdump'd the communications? Is anything happening?

You've done all the normal cookie stuff that you need for non-SSL 
distribution or in other words can you get non-SSL distribution working 
(perhaps locally...)?

What does epmd say about the nodes it knows about? I think you can run 
it in debug or console mode, or otherwise get it to dump the known nodes.

Cheers,
Bruce
