[erlang-questions] erl -name foo and hostname

Well my problem is resolved now: I just needed a missing host entry (with
the proper IP and FQDN) on my Ubuntu 16.04 systems and it is running now. I
also tested the connection between different machines, and they can "find"
each other without any problems now.


Regards,
Boris
