Open ports

I did a scan against myself and found:

PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
111/tcp open rpcbind
631/tcp open ipp
674/tcp open acap
6000/tcp open X11

I don't mind having port 22 open, but I don't see the need for the
other ports. How do I turn all that crap off? Is any of it necessary?

Thank you.

Open system-config-services and disable anything you're not running. Also be sure most ports are closed in system-config-securitylevel.
