Thanks for the feedback. We are still running into a roadblock.. and
perhaps it is something simple in the setting up of the display
environment. here is what we have troubleshot so far:
- We are using Xvfb for an X-server.
- We have invoked the latest GLX for Xvfb (as far as we know)
- We are starting Xvfb from the command line using "Xvfb :9 -screen 0
1280x1280x24 &" as described in
this post (
http://www.unidata.ucar.edu/mailing_lists/archives/idvusers/2010/msg00002.html
)
-We made a duplication of runIDV called runIDV2 where we include the
following lines at the beginning of the file
DISPLAY=:9
export DISPLAY
-We execute runIDV2 using our test.isl file to create a graphic and we now
end up with the following error:
"client 1 rejected from local host"
Are these the correct steps to do this? It seems like we are doing
something wrong.
