Are you running xinetd or inetd?

As for X
edit your startx script

which startx

will give you the location

near the top you will see something like

defaultserverargs=""

change it to look like

defaultserverargs="-nolisten tcp"

is there a command in ssh that can do it

Any non-gui text editor will do it.
Try pico or nano. My favorite "easy" editor is joe.

nano `which startx`

will get you going.
notice that those are back ticks not apostrophes.

use iptables to block all ports you dont need open.
blocking is even more secure than just closed.

iptables is the linux firewall.
