When I run nmap on my enterprise box I get a list of ports (see below). Sunrpc I presume is used for an NFS mount I have to another box, ncd-pref is also related to caching of the mount (I'm guessing) ... but what is sometimes-rpc3 and do I need it open? Also ... why is X11 open like that twice when I run X on another box and use it with vnc etc without having to leave a port open specifically for X11 or X11:4.
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on pblade2 (127.0.0.1):
(The 1593 ports scanned but not shown below are in state: closed)
Port State Service
22/tcp open ssh
80/tcp open http
111/tcp open sunrpc
443/tcp open https
5977/tcp open ncd-pref-tcp
6000/tcp open X11
6004/tcp open X11:4
32770/tcp open sometimes-rpc3
I do appreciate your time and advice.
Thanks.
