Attaching a shell to a running node.

[Serge Aleynikov]

In the embedded mode you need to start the node using "run_erl" command, 
and use "to_erl" to attach to the node's console.

See:
http://www.erlang.org/doc/doc-5.5/erts-5.5/doc/html/index.html

This is a preferred way for running embedded systems in production. 
Another benefit here is that all console activity gets logged in this 
mode, and run_erl takes care of file rotations.

If you don't need to access the node's console, but just need to run a 
shell on a remote node, you can start a non-embedded node and use the 
-remsh option:

$ erl -sname b -remsh a@REDACTED
Erlang (BEAM) emulator version 5.5 [source] [async-threads:0] [hipe] 
[kernel-poll:false]

Eshell V5.5  (abort with ^G)
(a@REDACTED)1>
