About Erlang system nodes

I just don't find any clues in otp source code that the primitive command "!" is related to the communication module selected through -proto_dist option.

I can sniff the ip packet to see what happens if we run erlang/mnesia over SSL.

    communication between Mnesia nodes even if SSL is employed. Is that correct?

    Thanks a lot,
    Renyi.

  Hmm..I don't know about that. I never tried erlang dist over SSL. When you say you found out, how did you find out? Did you sniff the IP traffic between the nodes and successfully decode them?
