Does my system have a worm?

[Jim Byrnes]

I have Apache2 installed using localhost on my desktop and have been 
trying to figure out how to configure it so I can access it from other 
machines on my network.  As part of this I used the Network Tools to run 
a port scan.  I recognize all the open ports except port = 2002, state = 
open, service = unknown.

I googled port 2002 and the first hit was 
http://www.f-secure.com/v-descs/worm_linux_slapper.shtml. I don't have 
any process running called .bugtraq or any of the files them mention, so 
I guess I'm ok, but how do I find out what has port 2002 open?

Thanks,  Jim
