When trying to start rabbitmq server, I get the following error:

I tried erl -sname foo command and it gave a similar error.
Then (as suggested here: http://permalink.gmane.org/gmane.comp.networking.rabbitmq.general/23204) I tried
epmd -debug and it gave the following output:
epmd: Mon Sep 29 11:56:16 2014: epmd running - daemon = 0
epmd: Mon Sep 29 11:56:16 2014: error opening stream socket: Address family not supported by protocol
Tried to google for epmd error Address family not supported by protocol, but couldn't find anything.
It might be that you are using IP6 address which might be not supported by epmd in your Erlang version. This mail might shed some light on issue (or just force IP4 if you can).
