Connection attempt from disallowed node 'ejabberdctl-1@localhost'

Question

The title is what appears in my ejabberd log files after an unsuccessful start. I did some googling and have noticed it is probably related to my cookies..

Running get_cookie() in the erlang shell prints 'nocookie'. Is this typical for a fresh install of erlang? How should I ideally go about setting the cookie?

Answer 1

nocookie would likely mean that the node hasn't been started in distributed mode. All distributed nodes otherwise have a cookie.

You will have to make sure your node is started in distributed mode (through -name or -sname arguments) for things to work.

In case the node is already started and you have access to a shell, you can start the distributed kernel by hand with net_kernel:start([Name, shortnames]) or net_kernel:start([Name, longnames]).
