[erlang-questions] Making rpc calls from escript

I believe you probably need to start net_kernel in order to make that
rpc call. Without net_kernel running, there is no distributed Erlang.

You should be able to do something like:

net_kernel:start([foobar, longnames]).

(Assuming your hostname is properly configured).

Hope that helps,
