Newbie server Question

[Stephen Hinton]

Ok,
    I am trying to get VNC to run as an on-demand service because I
would ultimately like to remove the monitor and keyboard from my
server and administer it remotely in entirety.  However, I'm not savvy
enough yet to be confident I can do that without my GUI crutches.  I
am running into a very simple problem that is probably more linux
related than VNC related, but I still need help.  I'm running Fedora. 
I can get VNC operational on a 'per-user' basis using the nice GUI
'desktop sharing' interfaces.  However, I cannot find any GUI setup
that will allow VNC to run 'on-demand' to provide a remote login
screen, etc.  So I found and followed the very nice, very explicit
"VNC on UNIX-like systems - step by step guide." that are found
reproduced on several websites
(http://www.mythic-beasts.com/~hobb/main/index.php?pagename=VncOnLinux
).  However, I cannot for the life of me get Xvnc to 'listen' on a
port.  Which obviously prevents anything else from working as far as
vnc goes.  I have created the entries in /etc/services, I have created
the corresponding vncservers file in /etc/xinetd.d/ .  I have enabled
XDMCP (which should be beside the point).  I restarted xinetd.  When I
do a 'netstat -tl' i do NOT see any service listening on my 595x
ports.  It should be listed as listening even if no one is connected
right?  In fact, I would think it would be listening just from the
entry in the /etc/services file even if I screwed up the server
settings in xinetd.  But then again I am a noob.  So someone tell me
what obvious mistake I am making here.
