AW: [mapserver-users] Troubleshooting a cascading mapserver install.

[Eichner, Andreas - SID-NLKM]

Just tried a simple request on a WMS server you're cascading: http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?layers=nexrad-n0r-m05m&STYLES=&FORMAT=image/png&width=512&height=512&bbox=-180,-90,+180,+90

resulted in the following error:
msSaveImageGD(): Unable to access file. Unable to open file /mesonet/www/html/tmp/nexrad_base_reflect129828395630777.gif for writing

Looks like the cascaded ones already have a problem. Check that first.

Hi all, I've recently setup a mapserver install on a linux machine. So
far the mapfile is written to pull other images from other servers. But
unfortunately I get a blank return image and using google earth to
display shows a big red "X"!

Here's the mapfile:

END # Map File

Testing with shp2img works and I get some nice outputs from my mapfile.
But once I pop it into a wms client, nothing seems to show. Is it my
extents boundaries?
