It "looks like a connection issue between"... or your windows firewall denies connections to port 6000. Add an exception.

You can test of course using the same procedure (telnet) from HP-UX. If this is not working, check the firewall from Windows(disable temporary until you will add the exception), check any firewall between HP-UX and Windows. If you have a firewall between HP-UX and Windows and you can not manage it (it is not yours/etc...) you should implement a VPN between those using an open port in the firewall.

Best regards,
Horia.

Xwindows is often blocked by netywork administrators as it is not a secure protocol. However, you don't need an Xserver running on your HP-UX system at all unless youabsolutely want to replace your PC desktop with the CDE desktop from HP-UX. This is what Reflection/X does out of the box when you use one of the connection dialogs.

After you install Reflection/X, run the optimizer then configure Reflection/X to start minimized. Now the Xwindow emulator is running on your PC and you can start an X application. Just ssh (or telnet) to the HP-UX box, then run xclock like this:

export DISPLAY=:0.0
/usr/bin/X11/xclock &

This should pop up the xclock window on your PC (it might start minimized). This all assumes that ssh or telnet to the HP-UX box works OK and that Xwindow ports are not blocked on your network routers.

Once xclock runs OK (and you really want all that CDE stuff on your desktop) you can configure CDE. NOTE: CDE desktop utilities may not have been installed automatically as they were on previous versions of HP-UX. Use your Install DVD to add the CDE code to your system.

You don't need an X server running on your
HP-UX system unless you have
keyboard-pointer-graphics hardware on your
HP-UX system. An X server is the thing with
the display, not the thing which tells the X
server what to display. The _display_ (with
its keyboard-pointer stuff) is what gets
served by the X server. The X client is the
system which lacks its own display (or isn't
using the one it has), so that when it runs
xclock (or CDE, or whatever), it needs to use
a display which is served by some other
system (the X server).
