Cannot connect to Elixir instance (Elixir 1.5.2 & Erlang 20.1.5) #156

Closed ghost closed 6 years ago

ghost commented 6 years ago

Tried connecting to a running iex instance - GUI Message "Cannot connect to peer node"

But confirmed the node could be ping'd etc.

(test@127.0.0.1)3> net:ping('blah@127.0.0.0.1').
pong
iex(blah@127.0.0.0.1)3> :net.ping(:'test@127.0.0.1')
:pong
iex(blah@127.0.0.0.1)5> :erlang.get_cookie          
:test_cookie
iex(blah@127.0.0.0.1)6> :erlang.node                
:"blah@127.0.0.0.1"

Steps to run - and exception on CLI. 

git pull origin && ./mvnw clean compile install assembly:single && java -jar target/*runnable.jar

Incidentally, I'd attach a screenshot but github's telling me, "Something went really wrong, and we can't process that file??" ha ha.

Anyway, I could connect to an Erlang instance 'test@127.0.0.1' - worked great - but 'blah@127.0.0.1' it just doesn't like.

ghost commented 6 years ago

Can't reproduce it again.. weird.

You have an extra zero in your node name ip.

iex(blah@127.0.0.0.1)6> :erlang.node
:"blah@127.0.0.0.1"

ghost commented 6 years ago

??? how did it ever resolve? thanks @andytill

andytill commented 6 years ago

No worries, maybe it parsed as a hostname because it didn't fit the 4 char format.
