Chooser failing
For years I have had two linux machines (inside firewall) using the X
chooser so that I could log in either to self or other machine. This
has worked with kdm or xdm.
Now I am failing to get this to work with Debian Lenny on both machines
(last worked with Sarge). It allows login to self, but choosing the
other machine gives only the gray screen. If I don't use the chooser
and do "X -query" to the other machine, I get the remote login window
with no problems. I have tried whatever I could think of in kdm and
xdm. I even added
LoginMode=DefaultLocal
to the [X-*-Greeter] section in kdmrc because the manual says the
default is LocalOnly.
Probing packets, I see:
Query ->
Willing <-
to populate the Chooser. When I choose the other machine, I get
ForwardQuery ->
three times and no response. This surprised me because the XDMCP
protocol led me to expect
Request ->

Searching, all I could find was a page of unknown date that says xdm
does not follow XDMCP protocol.

Another strange thing: I set
ARG="$ARG -debug 0x9FF"
(or 255) in /etc/init.d/kdm but I am not getting debugging information.
Does anyone have a suggestion?
