[erlang-questions] erlang gen_tcp:connect/3 not working with rpc:call/4, anyone knows why?

[Allen Kim]

Is it environmental issue?
I see the same error on my Mac OS X laptop.

~/open_source/EMG/loadtesterl$ssh
  'erl -name
 -detached -setcookie loadtest'
~/open_source/EMG/loadtesterl$erl -name
 -setcookie loadtest
