This module is deprecated. For a description of the Magic Cookie system, refer to Distributed Erlang in the Erlang Reference Manual.
Use erlang:get_cookie() in ERTS instead.
Use erlang:set_cookie(node(), Cookie) in ERTS instead.
Returns yes if communication with Node is authorized. Notice that a connection to Node is established in this case. Returns no if Node does not exist or communication is not authorized (it has another cookie than auth thinks it has).
Use net_adm:ping(Node) instead.
