Re: Using XWin.exe to connect to a linux X Server



Not to leave you hanging, the problem was the xdmcp was not enabled. But there is another problem, which has nothing to do with cygwin. Somehow, my userID has something weird. Other co-workers are connecting fine, but my user ID is not working from any machine. They can login from my cygwin setup with their logonID without any problem, but my userID just does not work. From my setup and their setup.


This is a Gentoo x86 server running gdm. In case anyone has heard anything about it.

Thanks for the help.

don't seem to be able to open an xterm. All I get is a full screen
without anything. I am running this command:


XWin -query d-tuxedo

Are you sure XDMCP is enabled on this server? Try Xwin -query gentoo.numeric.ip -from windows.nummeric.ip
I did that and I get the same thing. I get the Cygwin X Window with the
title,


Cygwin/X - d-tuxedo.na.xde3.xerox.org

Because I think I am connecting, but I am not getting anything yet.


What you get if you try to connect with XDMCP (that's the protocol you
are using if you chose -query) is completely depending on the settings
of the gentoo Server.
Usually that would be a login window.
If you don't get anything, i assume xdmcp is not enabled on the
gentoo box. Check if a process is listening to udp port 177
(netstat -unlp |grep 177).

So, here is what I get,


d-tuxedo 10:14:06-> su
Password:
d-tuxedo jicman # netstat -unlp |grep 177
d-tuxedo jicman #


so, I guess so, maybe XDMCP is not enabled. But I am able to get into
gnome when I am in front of the machine...

Yes, looks like xdmcp is not enabled. If you sitting at the machine you don't need xdmcp, only if you want to connect via the network.
Enable xdmcp or use ssh tunneling. I recommend the first.

ssh is enabled, though. That's how I connect to it from windows. I use putty or cygwin.


let me enable xdmcp.

Ok, so I enabled xdmcp and now I have a beautiful gnome signon screen. But,
after login on, the screen disappears and the gnome signon screens appears
again. Here is the output of the cygwin command line:

So, I don't know where this DISPLAY above is from. Is that the correct display?

Tahnks so much for the help and we are almost there, folks. :-)
