Bug#235331: xserver-xfree86: [core system] X -query doesn't connect to XDM 4.1.0
Package: xserver-xfree86
Version: 4.3.0-0pre1v4
Severity: normal
Since some week, my testing machine cannot connect to debian stable machine
running XDM.
I connect to that machine in this way:
sudo X :1 vt8 -query 05-as001 -fp tcp/05-as001:7100
The remote machine has X 4.1.0 installed and the connection was working from
testing up to two week ago.
When I execute the command, then I get a new DISPLAY, I get the dotted
background and nothing more. so I have to close X using the keys combination.
The connection works as espected if I connect to a debian testing machine.
I did try connecting from a powerpc machine to many different i386 machines.
Using ethereal I found that the packet exchanged are:
XDMCP Query
XDMCP Willing
XDMCP Request
XDMCP Accept
XDMCP Manage
The last packet is sent many times from my machine to the XDM server, until I
stop the DISPLAY, so maybe this is a bug (a denial of service) against the
4.1.0 version.
Bye,
Giuseppe
