DISPLAY problems
xhost: unable to open display
I have set my DISPLAY to the IP of my workstation and tried to run xhost +, but xhost + returns the same error.
I have been able to do this from a B class CDE workstation and a PC workstation running Exceed.
I would like to use Power Term because of the CDE-like features, but I've tried everything I know and still can't run GUIs from this terminal.
I researched other issues concerning DISPLAY, but they were all regarding NNM or CDE, which doesn't appear to apply to my situation.

Re: DISPLAY problems
Please verify that the xserver is running on your PC by telnetting to port 6000 (xwindows) it is possible that it is not running the xserver and so there is nothing for the N class x client to connect to:
telnet yourpc 6000
(you should be able to type a couple of characters before it closes the connection)

Re: DISPLAY problems
First of all, make sure that your HP box knows your PC name.
nslookup your_pc_name
ping your_pc_name
if both work OK, set your DISPLAY variable to 'your_pc_name:0'
'xhost +' is only necessary if your workstation is a unix box, it's not needed by a X11 emulator like Exceed. Its purpose is to authorise a remote host to 'talk' to the local X11 Server.
Best regards,
Dan

Re: DISPLAY problems
I used to have to tell exceed to run the command on the remote host to have the display thrown back to the PC, or use XDMP to grab X:1 from the UNIX box. This may be the case with your app.
From the UNIX side, all you ever need to do is set the DISPLAY variable. I.E.
>export DISPLAY=2.2.2.3:0
#safest to use the PC's IP than hostname because windows can not resolve itself most of the time.
If the DISPLAY is not correct, or has no access then GUI commands will fail. Contact the vendor of the Winblows app to find out how to open the Xdisplay on the PC.
Regards,
Shannon

Re: DISPLAY problems
All of you gave good advice, but it boils down to privledeges being locked down on the NT side. So much for trying to stay productive...

Re: DISPLAY problems
Does PTP contain any log files ?
On the nclass do you have dtlogin running or simiar X or window manager processes ?
More detail required on your setup .....
FYI : If you have access to a bitmapped display/ Xsession on the PC =>
1. telnet to N class
2. export DISPLAY=N class_ip:0.0
3. run xhost+
4. export DISPLAY=pc_ip:0.0
5. run sam, xclock (-displayname) etc .... ? Results ?
Also be aware of X user based authentication, i don't think relevant yet as you can't even open the display net alone get access to it.
Check nslookup between PC's and N-class is working correctly ... good luck
