Cygwin on a Windows 7 Box.
Start Cygwin Bash Shell and issue startxdmcp command:
startxdmcp.bat 10.12.13.14 # where 10.12.13.14 is the IP of the remote Linux Box # you are trying to get a login window from # try it raw aswell, no change XWin.exe -ac -query 10.12.13.14
Windows 7 Cygwin XWin displays black / blank screen
Make sure the DNS Record for you local computer is correct
rem Find out what the dns server thinks the IP Address is C:\Users\jmuser>nslookup mypc Server: dnsserver.home.local Address: 10.12.13.4 Name: mypc.home.local Address: 10.12.13.20 REM This differs from what the actual address is 10.12.13.107 REM Issue ipconfig command to re-register the workstations REM DNS Record REM You have to be an administrator to do this I think. C:\Users\jmuser>ipconfig /registerdns Windows IP Configuration Registration of the DNS resource records for all adapters of this computer has b een initiated. Any errors will be reported in the Event Viewer in 15 minutes. REM Check that it's worked. C:\Users\jmuser>nslookup mypc Server: dnsserver.home.local Address: 10.12.13.4 Name: mypc.home.local Address: 10.12.13.107
So as far as I can tell if the DNS record for you XDMCP client is wrong the remote Linux computer serving the XDMCP login screen will resolve the wrong IP and the login screen won’t appear on the local computer.
startxdmcp.bat 10.12.13.11 # working now
