Functions

cookie() deprecated

Use erlang:get_cookie() in ERTS instead.

is_auth(Node) deprecated

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).

node_cookie([Node, Cookie]) -> yes | no

Sets the magic cookie of Node to Cookie and verifies the status of the authorization. Equivalent to calling erlang:set_cookie(Node, Cookie), followed by auth:is_auth(Node).
