Ok. thats a pretty cool after you use the stop command it says done. But how would you do that on these two ports below?

PORT STATE SERVICE
111/tcp open rpcbind
6000/tcp open X11


Example:
Code:
 thermalscript@linux:~> su
Password:
linux:/home/thermalscript #

Code:
 rcrpcbindd stop
bash: rcrpcbindd: command not found

Code:
 rcX11d stop
bash: rcX11d: command not found

These are giving me trouble, how would you do those?
