When I did a NMAP port scan, I get the following message:
Starting nmap 3.50 ( http://www.insecure.org/nmap/
) at 2004-05-27 08:22 CDT
Interesting ports on localhost.localdomain (127.0.0.1):
(The 1657 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE VERSION
111/tcp filtered rpcbind
6000/tcp open X11
Nmap run completed -- 1 IP address (1 host up) scanned in 3.705 seconds
I use X11 applications at work, so I set my DISPLAY to my home PC and
run those, when I work from home.
What are the consequnces of closing these ports? My PC is behind a NAT
router. Is this even an issue? When I did internet security vulnerability
test at http://www.grc.com
, it gave my PC a clean chit of security.
