Those ports are probably X Windows. At least that's what port
6000 is. That will be there even if you are not logged in and just
have xdm/gdm/kdm graphical logins up (since they need X up).
If you are using ssh, you also get ports in this range when ssh
is forwarding X connections. That may be what your port 6010 is but
I'm not totally sure on that one. I generally see ports 6001 and/or 6002
on forwarded connections but they are merely additional "display" numbers
so 6010 is certainly within range and reason.
Having these ports open allows you to connect to your X display
from other systems. This you may or may not want to do. Most people
who have multiple systems do want this enabled. There is an option to
X to disable it and a config option for ssh not to forward X11 connections.
You can also block it using the firewall code. As long as you haven't
allowed external connections by running xhost, you probably don't have to
worry too much about these ports.
If you want to track down what process has these ports open, try
running fuser or lsof. I personally prefer lsof. It generally doesn't
get installed by default, but it should be on your distribution install
CD if it's not already on your system.
