I have successfully installed and configured VNC on RedHat 7.1, but when I do
the same IDENTICAL changes on RedHat 7.2 I only get the grey screen. It
appears that I am unable to figure out how to enable the xdm as a daemon
(listening on port 177?).
Here is a list of the things I changed on the 7.2 box.
1) COMMENTED OUT the line 'DisplayManager.requestPort: 0' (should be the last
line) in '/etc/X11/xdm/xdm-config'
2) UNCOMMENTED the line '# * #any host can get a login window' in
'/etc/X11/xdm/Xaccess'
3) REMOVED the '-nodaemon' option in 'x:5:respawn:/etc/X11/prefdm -nodaemon'
from the last line in /etc/inittab.
4) ran gdmconfig and enabled XDMCP
I only performed item #1 and #2 above on my RedHat 7.1 box and got it to work
just fine (with valid xinetd setup). I also ran 'su -c "nmap -sU localhost"'
and no udp port existed for XDMCP. I've tried setting user=root
(/etc/inetd.d/vncserver service arg) with no change. There appear to be no
errors when loading the xinetd service. I don't know if/where Xvnc logs any
errors. I haven't been able to find any yet at least. Can anyone offer any
advice? How do I enable XDMCP w/ the xdm/kdm/gdm shipping w/ RH 7.2?
Thanks,
Jeff
FYI, my vnc binaries are in /usr/local/bin. Here are the lines from my
/etc/services:
vnc-640x480x24 5970/tcp
vnc-800x600x24 5971/tcp
vnc-1024x768x24 5972/tcp
vnc-1280x1024x24 5973/tcp
vnc-1600x1200x24 5974/tcp
I also have the following entries in the file '/etc/xinetd.d/vncserver':
service vnc-640x480x24
