xdm

[Tatar Kolos <tk123 hszk bme hu>]

Hi all.

I'm afraid this is not the proper place to ask this question, but i think
you guys could help me.

My problem is this:
I started xdm, and then from another machine, i tried to login to my
machine with this command 
X -query my_machine_name :0
This should have worked, but is hasn't.
So what should i take a look at?
Of, and the error message was: Host unwilling, manager unwilling...
