Hi  
  
 I'm running several boxes on Gentoo. I just didn't get xdmcp working, thou I 
proceeded all the steps I can think of.  
  
 I am trying to get kdm's remote login to work using xdmcp.  I have set  
 [Xdmcp]  
 enable=true  
 on /usr/kde/3.3/share/config/kdm/kdmrc.    
 In /usr/kde/3.3/share/config/kdm/Xaccess, I have  
 *                                       #any host can get a login window  
 *               CHOOSER BROADCAST       #any indirect host can get a chooser  
  
 I've tried to connect 3 ways using xdmcp.  
  
 (1) Using kdm remote login:  
 When I ask for a remote login in kdm, I get a nice chooser window with a  
 list of computers.  But when I try to select one, X restarts TWICE and  
 brings me back to my local kdm login.  I also get this error in  
 /var/log/kdm.log  
  
 Fatal server error:  
 XDMCP fatal error: Session declined No valid address  
  
 Why doesn't it work the ordinary way???  
  
 (2) direct query from command line:  
 If I run  
 X -query foo  
 I get a remote kdm login windows on another computer (foo).  I can login and  
 everything works perfectly.  
  
 (3) indirect query from command line -> remote computer  
 If I run  
 X -indirect foo  
 I get a chooser which I think is being provided by computer foo.  When I  
 select a computer from the list, X restarts ONCE, and then I get a nice  
 login window on whichever computer I want.  I can login and everything  
 works perfectly.  
  
 (4) indirect query from command line -> local computer  
 If I run  
 X -indirect localhost  
 I also get a chooser. Selecting foo although simply gets me no connection neither 
errors. Just starring at the awful grey background from the X server that dosn't do 
even less than nothing.  
  
 So it seems that there is something wrong with the way that kdm is  
 envoked, and that whatever is causing the problem is local.  
  
 I don't know where to start looking for the error.
