Hi All,
I use at work Rflection X to access Server Running on Solaris 10. There are applications running there so what we do is just connect to that using IP address. Then comes login windows and starts GUI

I can login to commandline via putty but cannot start the CDE session to start GUI. Is this possible? Yes, How?

Quick summary for : PuTTY + an X server on Windows can forward individual X applications (xterm, xclock) over SSH (X11 forwarding). That will not create the CDE/dtlogin screen — a full remote desktop login uses XDMCP (or a VNC/Xvnc desktop) rather than SSH X11 forwarding. (documentation.help)

If you want the CDE login window from Solaris you must run an X server on Windows in XDMCP mode (the server issues an XDMCP Query to the Solaris display manager). Xming/XLaunch supports this with the -query option, but the Solaris display manager (dtlogin) must have XDMCP enabled and UDP port 177 reachable. Many people see the dtlogin window but then “hang” because Solaris expects particular fonts/bit depths or needs a font server — that can explain the Xming behavior you reported. (straightrunning.com)

Practical options and next steps:

  • For single apps keep using PuTTY + an X server (start Xming/VcXsrv or use MobaXterm) and enable “X11 forwarding” in PuTTY.
  • To get the full CDE login: try Xming/XLaunch with -query <solaris-ip> after confirming XDMCP is enabled on Solaris and firewalls allow UDP/177.
  • If the site will not enable XDMCP (common for security), run a VNC desktop on Solaris (Xvnc/vncserver) and connect with a VNC client — that is the simplest way to get a full remote CDE session. (straightrunning.com)

Example commands (Windows side):

"C:\Program Files\Xming\Xming.exe" -query 192.168.1.10 -clipboard

Example command (Solaris side to start a VNC desktop):

vncserver :2

If XDMCP gives the login but apps never appear, try pointing the X server at the Solaris font server or adjust the display bit depth (CDE on Solaris can be picky). If security/firewall rules prevent XDMCP, use VNC or keep X11 forwarding for individual GUI apps. (x.cygwin.com)

I got putty to work with Ximing though ximing is having problems as I can't start my apps. Is there another X-server for windows?
