- Reply-to: cygwin-xfree at cygwin dot com
I have run into a problem again where I am unable to start a session
using XDMCP. I am trying to connect to multiple remote machines
running CentOS 5.5 using XWin 1.10.2.
When I run the command
xwin -nodecoration +xinerama -screen 0 @1 -screen 1 @2 -from
10.3.12.47 -query 10.3.147.22
I get two black windows (with no titlebars) that do nothing for a
while and then eventually close and reopen. If I watch what's
happening using Wireshark, I see
Local Machine Remote Machine

Willing

(many more times)
If I look in the XWin log, I see
[...]
[719987.046] XDM: too many retransmissions, declaring session dead
[...]
(the full log is pasted below). Oddly, for some remote machines, I
occasionally see this behaviour while most of the time it works but
for others, I seem to get this behaviour all the time and it never
seems to work.
Any help would be greatly appreciated.
