Hi all,

I am using Fedora Core3 on my system.
I have completed the procedure twice outlined in many XDMCP-HowTo documents.

When I attempt to connect to my system from my friend's one who is also running Fedora Core through XDMCP, the connection time out error pops up.

I have revised all X server configuration on my system, but failed. I am using XDM. The problem that I figure out is the output of the command:
netstat -l | grep xdmcp

There is no line I get; it means UDP port 177 is not open on my system. My system is simply a system just like anyother system on the local network.

We have dedicated server on our local network, and when i try to connect server through XDMCP from my system or my friend's one, it allows to connect. Its means X server is correctly configured on the server machine.

I don't understand why X server is not working on my system????

Any idea to turn on UDP explicitly? How should i tackle this problem???

Thanks in advance,

Did you flush the firewall rules with iptable -f?
Can you ping?
Have you changed the Xaccess to allow everybody?
Also, do not trust netstat. xdmcp may not be registered. It is not on my system.

Thanks for your prompt reply....

Yes, i have issued command iptables -F.

I can ping my system from any other system on the network

I have changed /etc/X11/xdm/Xaccess to allow every one to connect to X server running on my machine.

Any thing else.......I would like to hear more from you....as I have tired to figure out why????

What does "X -query hostname > help" have in it exactly?
