Installed via RPM on RH 7.2 CD

Done!  I know that XDMCP is working because it is allowing X connections
from thin clients (diskless NCDs)

I did not receive this file, however this is what my /etc/services looks

vnc-640x480x8   5950/tcp                        # vnc server IP
vnc-800x600x8   5951/tcp                        # vnc server IP
vnc-800x600x16  5952/tcp                        # vnc server IP

I did not recieve this file, however this is what my
/etc/xinetd.d/vnc-640x480x8 file looks like

service vnc-640x480x8
        disable                 = no
        socket_type             = stream
        protocol                = tcp
        wait                    = no
        user                    = root
        server                  = /usr/bin/Xvnc
        server_args             = -inetd -broadcast -once -geometry
640x480 -depth 8
        log_on_success          += USERID
        log_on_failure          += USERID

When I do this xinit restart command I get some errors:

_XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running

Fatal server error:
Cannot establish any listening sockets - Make sure an X server isn't
already run

When reporting a problem related to a server crash, please send
the full server output, not just the last messages.
This can be found in the log file "/var/log/XFree86.0.log".
Please report problems to xfree86 "at"

Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
giving up.
xinit:  unable to connect to X server
xinit:  No such process (errno 3):  Server error. 

These errors seem to occur whether the vnc files are in the
/etc/xinetd.d direcotry or not :-(
