XDMCP phenomenon

[Dirk H. Schulz]

Hi Folks,

I am using Cygwin for more than a year now to log into several machines via 
XDMCP.


No I am transferring my admin workstation. And with cygwin on the new 
machine there is a problem I did not have before:


- using "X -broadcast" gives me the login screen of one of my servers, and 
I can work with it as usual.
- using "X -query HOSTNAME" in all variants I know leads to a blank grey 
screen with no login of my servers, even if I substitute HOSTNAME with the 
one that always wins the race at "X -broadcast".


So all of the normal cures against the "no login" problem (like allowing 
XDMCP on the server you want to log into) are of no use - all thas has been 
solved a year before when I started using Cygwin.


I have looked into netstat on the cygwin box. After the "X -query ..." 
there is a connection on port 6000.


Now googling for this phenomenon brought nothing enlightening, googling for 
"XDMCP no login cygwin" only leads to 2 million variants of "enable XDMCP 
on your server".


I am quite stuck. Any hint or help is appreciated.

Dirk

did you try X -query numeric.ip.address -from x.server.address ?

Hi Holger,

thanks! That brought me onto the right track.

I had checked for name resolution to work on the Cygwin box (nslookup in 
DOS window), so I never tried using the ip address directly; but in 
Windows' hosts file (which Cygwin symlinks) there was a wrong entry for my 
servers.


Stupid mistake, sorry for disturbing, I should have found THAT on my own.

Thanks for your help!

Dirk

XWin.exe will not exit gracefully on Vista

[Mike Knope]

I finally have cygwin running nicely on Vista, however when I select 
exit then xwin.exe goes to almost 100% cpu and just stays there.  I have 
to use task manager to kill it.  I am using startxwin.bat to start up.  
The xwin line looks like this:

run XWin -multiwindow -clipboard -silent-dup-error

Everthing else seems to work just fine except for exiting.  Any clues?
Thanks,
Mike
