Hi Phil,
Thanks so much for the reply, however I think I didn't explain my
problem clearly. The script is already on the same server, I just need
the Perl script to attach to a display port (localhost:25 in this
case) when it is run nightly via cron, as the script creates images
that need an X window to process in. The point of me showing I can
successfully attach to the port via vncviewer was purely to
demonstrate that I have everything related to VNC working in a stable
environment.
After trawling the VNC mailing list archives all day yesterday I saw a
couple of threads about Xvfb - which might be all I need. However, I
cannot pass my Perl script a display argument, so I need to somehow
force the script to use the localhost:25 port. Hence why I had been
attempting to export the DISPLAY variable in my wrapper script
(attached again below).
hostname{user}1% cat mywrapper.sh
#!/bin/sh
DISPLAY=localhost:25.0
export DISPLAY
/path/to/myperlscript.pl -args
DISPLAY=localhost:0.0
export DISPLAY
However, it is still not working.
Best regards,
- Rob
