Hello sluggers,
I am a little outside of my element with fedora and am running into a
problem getting a fresh install to allow me to enable the XDMCP broadcast
enabled. There are a few wrinkles that may or may not be important though.
The main one is that this is a fedora image running on a VMWARE GSX server.
I don't think there are any network driver or addressing issues though since
I can ssh into the os running on the virtual machine. I have tried
following this basic how-to as found at:

Enable XDMCP under Linux

*Fedora Core 5*
If implementing a default intallation of FC5, it needs to add the xdm
(xorg-x11-xdm) package
into FC5 before enabling XDMCP.
1. Enable xdmcp in gdm configuration by editing the file
"/etc/gdm/custom.conf" and set xdmcp=ture.
2. Set xdmcp listen in "/etc/X11/xdm/xdm-config" by comment out the line "
DisplayManager.requestPort: 0" (add ! in the head)
3. Set the access control in "/etc/X11/xdm/Xaccess"
* #any host can get a login window
OR
192.168.0.* #any host can get a login window
4. Enable xdmcp in firewall. The simplest solution is to turn off the
firewall. Otherwise you need to edit the file "/etc/sysconfig/ipchains" with
the following in its' head
-A input -p udp -s 0/0 -d 0/0 177 -j ACCEPT
-A input -p tcp -s 0/0 -d 0/0 telnet -j ACCEPT
-A input -p tcp -s 0/0 -d 0/0 ssh -j ACCEPT
-A input -p tcp -s 0/0 -d 0/0 login -j ACCEPT
-A input -p tcp -s 0/0 -d 0/0 exec -j ACCEPT
-A input -p tcp -s 0/0 -d 0/0 shell -j ACCEPT
-A input -p tcp -s 0/0 -d 0/0 7100 -j ACCEPT
5. reboot the system to run new configuration.
_____________________________________________________________________
I actually turned off the firewall for the tesing purposes using "service
iptables stop" for the purposes of this testing.
After rebooting I still am not able to connect to the server using X-Win32.
It doesn't even seem to see any remote XDMCP server out there. I did a ps
-ef |grep -i dm to see if gdm/xdm was running and got the following output:
[root@lnxdevsvr xdm]# ps -ef |grep -i dm
root 1357 1 0 04:01 ? 00:00:00 rpc.idmapd

root 2964 1947 0 04:28 pts/1 00:00:00 grep -i dm
I noticed this "---nolisten tcp vt7--" in the output that concerned me and
didn't know if it was part of the problem I was facing.
Any help would be appreciated
Thanks,
Keith
