karmacoma,
aMule must be running at the machine (in your case Moebius) *before* you run amulecmd. (Don't get me wrong, some people do that mistake, just checking

). The connection between amulecmd and aMule is usually done through TCP port 4712, which is the default external connection port. Unless you have changed that, this should work.
Well, seems to me that you are using rc5, and maybe amulecmd-rc5 does not accept the -f parameter, but that is just to make users life easier... You can always type the password by hand

Connecting to TCP port 4662 will not work. With the configuration parameters you have, you would have to do $ amulecmd -p 4672, which is not default.
Do the following in your configuration:
Preferences->Remote_Controls->External_Connection_Parameters:
Change the External TCP port to 4712.
That way you have default values right and will not need -p .
Anyway, I would advise you to use a recent cvs tarball instead of rc5, because there have been *many* changes to that code and many bug fixes.
