Applications unable to display

[Patrick Murphy]

Several applications running on a new C3600 using HP-UX 11.00 are unable to open their displays when launched from a remote login session using Exceed (V7.1.0) from a PC. A message like "Display not Found" or "Unable to display is found" Other applications work just fine. The work around is to assign the DISPLAY variable to acutal PC's IP address instead of the name assigned to that IP (i.e. export DISPLAY=WWW.XXX.YYY.ZZZ:0.0 instead of Some-silly-name:0.0) Using nslookup we find that the name is resolved properly to the IP and vise versa. I have found that making the following assignment at login gets around this DISPLAY=`who -u am I | awk '{print $8":0.0"}'` I would assume that something is wrong and I should not have to do this. Your thoughts would be greatly appreciated

Hi,

I believe the problem lies in the name resolution.

Where are you trying to nslookup from?.

Once the remote login is established and if you do a 'nslookup some-silly-name', does it print correct IP address?.

It is not recommended to hardcode the DISPLAY variable into .profile unless you check for the variable "DT". Look at .dtprofile for more information.

We are performing the nslookup on the C3600 using both the name and the IP. In both cases the correct resolution is obtained. Name resolution seems to be working properly. Another method we utilized is ping from the C3600. I have been told that even if nslookup works, ping may not. This activity works also.


I would agree that hard coding the Display is not desirable and should not be necessary.
