Thank you everyone , I really appreciate the time you took to answer my question.
The issue was the additional port needed to be open.
The cluster is up and running.

Dear David

Each nodes will need another port (or range of ports) available, and a full name.

I had the same trouble:


Best wishes

Hi Everyone,

I am unable to get 2 erlang nodes to talk to each other through net_adm:ping.
I am running on centos 6.3 and I am on amazon ec2.

Port 4369 is open and I can telnet to it from both servers

The cookies are the same when I do a get_cookie.
When I try to do a net_adm:ping it hangs for a while and return a pang.
I can resolve the hostname properly.

Anyone could guide me on what the issue could be?

Thank you,
