Re: Newbie question: vncserver running on port :25, need to attach Perl script to this when it executes

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
