I found the cause:
cat /etc/resolv.conf# Generated by NetworkManagerdomain localdomainsearch localdomainnameserver
After it I tested with DNS server (local server) - and everithing is ok.
so DNS...
Thanks You

 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.

I haven't responded earlier, because I am currently struggling with my Ubuntu 16.04 system at home, which I only installed some days ago. This system is a default fresh desktop setup, without any changes so far. It was quite a surprise, that invoking erl with "-name" results in a crash with a dump file being created. I haven't seen such a behaviour for quite some time now.

Well, this "new" problem currently keeps me distracted from Yours.

Actually what is interesting for me - if I do hostname = localhost.localdomain,
erl -name foo will show localhost.localdomain.
i am going to install DHCP/DNS and wil try to get hostname via DHCP

 Have You tried to ping "kazootest2.localdomain"? It would be interesting which IP shows up, if any at all. Maybe this gives a hint.Did You also have a look at "/etc/networks"?
