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 --------------- --------------- Query Willing Request Accept Manage Manage Manage (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. ------ Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 1.10.2.0 OS: Windows 7 Service Pack 1 [Windows NT 6.1 build 7601] (WoW64) Package: version 1.10.2-2 built 2011-07-07 XWin was started with the following command line: xwin -nodecoration +xinerama -screen 0 @1 -screen 1 @2 -from 10.3.12.47 -query 10.3.147.22 ddxProcessArgument - Initializing default screens winInitializeScreenDefaults - primary monitor w 1680 h 1050 winInitializeDefaultScreens - native DPI x 96 y 96 winInitializeScreens - 1 winInitializeScreen - 0 ddxProcessArgument - screen - Found Valid ``@Monitor'' = 1 arg winInitializeScreens - 2 winInitializeScreen - 1 ddxProcessArgument - screen - Found Valid ``@Monitor'' = 2 arg [719859.484] (II) xorg.conf is not supported [719859.484] (II) See http://x.cygwin.com/docs/faq/cygwin-x-faq.html for more information [719859.484] LoadPreferences: /cygdrive/c/Users/alpokluda/.XWinrc not found [719859.484] LoadPreferences: Loading /etc/X11/system.XWinrc [719859.484] LoadPreferences: Done parsing the configuration file...
