I am wondering wha port does amule use?

OS:RH9
I gona close ssh,sunrpc and by the way can anyone tell me how to close port 985.
After i close this port will it affect amule downloading speed?

And is there any accelerator for amule, coz it seems kinda slow.... 0.6KB......


Port State Service
22/tcp open ssh
111/tcp open sunrpc
985/tcp open unknown
6000/tcp open X11
