Hi Phil, re: > Of course, projects like these result in the domino effect. :-) > I have > tried to do something similar with our NEXRAD imagery, and have hit a > snag. To test, the script, I ran it from the LDM and get the error: > > Xlib: connection to "twister.sbs.ohio-state.edu:0.0" refused by server > Xlib: No protocol specified > > [GEMPLT -83] NDISP - DISPLAY not set or invalid The script you are running evidently needs to be able to connect to a running X server. This is a much different situation than the simple script you sent in before. > When I log into the LDM via Shell, I notice the Display variable is > not set... but it shouldn't matter since it's set in the script, > right? I've also tried localhost:0.0 and still have the same problem. > Interestingly, when I log into shell in Gempak and then log into the > LDM via su, it works. > > I have tried running the NEXRAD script as a gempak user from the shell > and passing the command line variables as the LDM would and it works > fine. I think the best thing for this effort is to send in a new inquiry to address@hidden. Steve Chiswell should be able to give you ideas on how best to address your script(s) that require an X server (I am not the GEMPAK support person). > Thanks again for your help Tom, No worries. I will close this inquiry in the expectation that you will open a new inquiry that is related to GEMPAK.
