Xmanger "XDMCP connection failed" on my Redhat AS 5.0

Hi All,


i config linux step by step with the following way provide by

Netsarang

For XDMCP connection to Red Hat 5 EL
1. XDM Configuration
1. Change runlevel to 5

Open/etc/inittab and set the initial runlevel to 5 as following:
id:5:initdefault:

2. Enable XDMCP

For GDM:

Open /etc/gdm/custom.conf and set the Enable entry to 1 in the [xdmcp] section as following.
[xdmcp]
Enable=1

For KDM:

Open /usr/share/config/kdm/Xaccess and remove the initial "#" character for the following line:
#* #any host can get a login window ==>
* #any host can get a login window
Open /usr/share/config/kdm/kdmrc and set the Enable entry to true in the [xdmcp] section as following.
[xdmcp]
Enable=true


2. Firewall (TCP/UDP Ports) Configuration
Open UDP port 177 from the PC to the remote host direction.
Open incoming TCP ports 6000~6010 from the remote host to your PC.
3. Reboot the remote host and start Xmanager
# init 3; init 5


But when i I use Xmanager connect to Redhat As 5.0,

i got the error "XDMCP connection failed,try again?"

Have the same issue, can any1 pls help me ?

Thanks

Anyone been able to resolve this?

Resolved.. I needed to add this:


1. Edit the /etc/sysconfig/desktop file to define GNOME as the X desktop environment that loads on connection.
1. Open the /etc/sysconfig/desktop file.
2. Locate the DESKTOP= entry. Note: The entry may need to be created and it is case sensitive.

Change this setting to: DESKTOP="GNOME"

3. Save the file.
