[erlang-questions] Erlang inter node communication issue

[David Chamard]

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,

David
