OS X - 'Nameserver not responding on ...'

[jordan0day]

I'm on OS X Yosemite and having an issue connecting to a node I'm running locally. I can connect the nodes using net_adm:ping, but erlyberly complains with "Nameserver not responding on Jordans-MacBook-Pro.trea..."

$ erl -name test -setcookie test_cookie
Erlang/OTP 18 [erts-7.2.1] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Eshell V7.2.1  (abort with ^G)
(test@Jordans-MacBook-Pro.trea.local)1>

...


$ erl -name test2 -setcookie test_cookie
Erlang/OTP 18 [erts-7.2.1] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

(test2@Jordans-MacBook-Pro.trea.local)1> net_adm:ping('test@Jordans-MacBook-Pro.trea.local').
pong

As per the troubleshooting section in the README, I've verified that epmd is running:

$ ps aux | grep epmd
jordan           9581   0.0  0.0  2497076    468   ??  S     2May16   0:01.23 /usr/local/Cellar/erlang/18.2.1/lib/erlang/erts-7.2.1/bin/epmd -daemon

I'm guessing this is probably something configured wrong on my system or domain or something, but I'm really not sure what I should look at next, troubleshooting-wise?

According to the comment below the java erlang driver does not allow full stops in the node name. Could you try with a node name without the full stop?

Yes, it works if I have a nodename without any period in it.

It also works for a node name with an IP (like test@127.0.0.1), but, interestingly, it also works when I start my node with

erl -name test2@Jordans-MacBook-Pro.local -setcookie test_cookie

So it's not necessarily the presence of a period that causes the issue. This makes me think it is most likely some kind of issue with my local network/os x's hostname configuration stuff.

Great, I have updated the trouble shooting section with this issue in e0c09c0.
